summary In this current era it is the information technologies that has set the stage for the drama of human life to be acted out. The information revolution has created global links on a scale unparalleled in human history. With exciting explorations into virtuality (the current buzz word) our life experiences, dreams and ambitions will be mapped into cyber-space and our "real" reality will become indistinguishable from our virtual reality. We are on the verge of experiencing a complete sensory immersion in this man-made cyber-dream. We will be able to enter virtual space that has as much richness and tangible quality as the world from which it sprang.

title Real Teaching and Learning through Virtual Reality
source International Journal of Architectural Computing vol. 1 - no. 1
summary This paper addresses an articulated vision of Virtual Reality, which lends itself to design collaboration in teaching, learning and communication of architectural design ideas among students, design professionals and client bodies during the early stages of the design process. Virtual Reality (VR) has already acquired a new degree of complexity through development of network-based virtual communities and the use of avatars. A key intrinsic quality of VR technology is to support collaborative design experience. The design tools developed for this experiment are capable of creating 3D objects in a shared VR environment, thus allowing the design and its evolution to be shared.The choice of programming language (JavaTM) reflects the desire to achieve scalability and hardware independence, which in turn allows for the creation of a VR environment that can co-exist between high-end supercomputers and standard PCs. The prototype design environment was tested using PC workstations and an SGI system running in a Reality Centre.

title Integrative Knowledge-Based Design Systems : A View
source The Computer Integrated Future, CIB W78 Seminar September, 1991. Unnumbered : ill. includes bibliography.
summary The paper describes a recent project whose objective was to redesign GIMSEX-PERT, an existing architectural knowledge- based design system developed in 1987. Its critical generative problems appeared to be the rigid structure and limited evaluation criteria. The project's outcome is DESTOOLS, based on the 'object-oriented-methodology' inspired by the traditional trial-and-error approach. It includes a set of interchangeable design methods that can be applied interactively by any desired sequence, producing or transforming a GIMS Building System object. Such 'moderately- loose' system structure offers flexibility in use, avoids pitfalls of knowledge-based design systems with rigid structure, and is applicable in design research, education and practice

source Architectural Computing from Turing to 2000 [eCAADe Conference Proceedings / ISBN 0-9523687-5-7] Liverpool (UK) 15-17 September 1999, pp. 33-39
summary The paper reflects on a thirteen-year period of CAAD research and development by a small group of researchers and practitioners. Starting with simple algorithmic drafting programmes, the work transcended to expert systems and distributed artificial intelligence, using computers as tools. The research cycle is about to begin afresh; computers in the next century shall not be detached entities but the extensions of man. The computer shall be the medium that will enable a designer to be what he/she really is. This future has already begun.

source The Virtual Studio [Proceedings of the 12th European Conference on Education in Computer Aided Architectural Design / ISBN 0-9523687-0-6] Glasgow (Scotland) 7-10 September 1994, pp. 15-23
summary A design studio of the future shall be based on dislocated, distributed design services, and feature the ‘design by collaboration’ enabled by the computer transmitted information. However, in a collaborative design process, computer may take an additional role, i.e., as an “ultimately structured dynamic communication medium ... based on the notion of commitment and interpretation” (Winograd and Flores 1987). Various models of ‘intelligent’ design systems based on the ideas of ‘open, distributed, artificial intelligence systems’ have shown that the computer-based design agents which act on the object-to-be-designed model could be involved in a “conversation for action” (Winograd and Flores, Ibid.). The aim of the paper is to illustrate a computer-based design system that enables ‘a-kind-of’ conversations by the design agents before the design decisions were made. After the description of a design experiment and the conversation that went on between the design agents, the traits of the applied ‘design design system’ are discussed.

summary The paper presents a progress report on a project investigating the possible application of a framework for cooperative-activities of computer design agents in the conceptual phase of architectural design. A process leading to definition of the expected performances of design agents is desribed, and some possible applications illustrated. The framework includes not only the objective, but also, the "subjective" agents. It is expected that the framework would offer an insight into the intricacies of CAAD in an educational environment, and provide the exploration paths and an efficient production of alternative solutions in an office.

summary The purpose of this paper is to present a recent design offer for design and realisation of a sizable housing development. The computers were significantly involved in both, making the offer, and organisation of project design phase. The story illustrates some interesting relationships between IT and certain types of design problems. The paper presents how the offer was prepared, discuss whether the computers would be beneficial in getting the design tasks done, and finally, pose the question whether such design tasks could be achieved without the help of computers. The explicit design tasks and use of the computer tools make this case of "computerised craftsmenhip" appropriate for presentation in educational environments.

summary The paper explores the use of in-house developed self-reconfigurable modular robotic system in civil construction activities and investigates a concept where an arbitrary Civil Engineering structure or a daily use industrial product are self-assembled from a number of self-reconfigurable composite blocks. The system extends current range of modular robot systems (mDrs) where autonomous modules self-assemble into a wide variety of forms. However, contrary to conventional mDrs, MoleMOD has not mechatronic actuating parts permanently fixed to each individual module. The MoleMOD actuators are separable and operate inside the modules, tight them together or relocate them to required configuration. It significantly reduces number of expensive mechatronics parts and the environment the actuators operate. Although MoleMOD focuses on architecture, it can take over other mDrs tasks as research and rescue. This paper describes properties, advantages, foreseen applications, and basic design specifications of the second generation prototype.

title Hands Free: A Wearable Surveying System for Building Surveying

summary Activities in the building industry in Europe concentrate increasingly on a combination of renovation and new-building. A prerequisite for comprehensive IT supported design and planning in the context of existing buildings is both the use of on-site computer- aided surveying techniques and the integration of all professional disciplines in an integrated information and communication system. The starting point is often the building survey on site. An examination of currently available IT tools and hardware shows insufficient support for planning within existing built contexts. Surveying equipment has been derived from other disciplines without being modified to cater for the specific needs of building surveying. This paper describes a concept for computer-aided digital building surveying equipment based upon a wearable computer and AR to close the gap between specialist equipment adapted for use in building surveying and the need for simple straightforward surveying equipment for architects and engineers.

source Abstract Book CIPA 2001 International Symposium, Potsdam 2001, pp. 58
summary Future tasks for the building trade in Germany will be more and more a combination of the fields of revitalization and new building projects. Prerequisite for computer-aided planing for existing buildings is both, the use of onsite computer-aided measurement and the integration of all specialists involved in the building process. Existing approaches for this problem are not yet satisfying. The aim of this research project is twofold: to design a practice-relevant software concept and to develop various prototypic systems, for a structured way of capturing and organizing building-related information about existing buildings in digital form. The research is oriented towards existing buildings, in particular residential and commercial buildings. This project is a special branch of SFB524. The project is founded by "Deutsche Forschungsgesellschaft (DFG)".

summary Activities in the building industry in Germany concentrate increasingly on a combination of renovation and new-build. A prerequisite for computer-aided planning in the context of existing buildings is both the use of on-site computer aided surveying techniques and the integration of all professional disciplines in an integrated information and communication system. Current approaches to these issues are unsatisfactory. Methods and techniques in renovation work are being investigated as part of ongoing research at the Bauhaus- Universität Weimar (SFB524 - “Collaborative research center 524 „Materials and Structure in Revitalization of Buildings”). A sub-group (SFB524 - D2 „Planning-Relevant Digital Building Surveying and Information System”) is currently investigating the possibilities of computer-aided building surveying and of joint communcation platforms for engineering disciplines (www.uni-weimar.de/sfb: May 2001). The objective is the development of a general approach for the renovation of buildings. The paper discusses concepts and requirements for a computer-aided system supporting the entire surveying process from the initial site visit to its use in a CAD system.

title Digital Building Surveying and Planning in Existing Building
source eDesign in Architecture: ASCAAD's First International Conference on Computer Aided Architectural Design, 7-9 December 2004, KFUPM, Saudi Arabia
summary For planning in existing built contexts, the building survey is the starting point for initial planning proposals, for the diagnosis and documentation of building damages, for the creation of objectives catalogues, for the detailed design of renovation and conversion measures and for ensuring fulfilment of building legislation, particularly by change of use and refitting. An examination of currently available IT-tools shows insufficient support for planning within existing contexts, most notably a deficit with regard to information capture and administration. In ongoing research at the Bauhaus-Universität Weimar (SFB524- Collaborative research center 524 “Materials and Structure in Revitalization of Buildings”) methods and techniques of revitalisation are being investigated (SFB 524, 2004). A special branch of SFB524- D2 entitled “Planning-Relevant Digital Building Surveying and Information Systems” is investigating possibilities of computer-aided building survey and communication platforms for architects and civil engineers. This paper discusses the concept for a modular surveying system (basic concept, structuring of collected data, separation of geometry from semantic data, and separation into sub-systems) and the prototypical realisation of a system for the complete support of the entire building surveying process for existing buildings. The project aims to contribute to the development of a planning system for existing buildings.

summary CA(A)D systems are nowadays a part of everyday architectural practice and have completely replaced drawing with pen and T-square. The standard functions of such systems are (usually) sufficient for the everyday needs of practical work. The question is: can CA(A)D systems be adapted to improve work efficiency for specific users or applications such as those of the architect? Most current CA(A)D systems already provide some level of support for individual adaptation however these are rarely exploited by the end users. This paper discusses the teaching of skills for adapting and extending existing CA(A)D systems in current architectural education. In addition to the teaching of programming and operational skills, the course also examines the critical examination of CA(A)D systems and the formulation of user requirements (analysis), the search for existing solutions, functions or extensions (research) and the technical adaptation or extension of the system (software development). Using examples from current coursework, the paper illustrates both process and results of teaching practice.

source Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary The application of new media is common practice in architectural offices and complements traditional forms of presentation such as drawings and physical ‘haptic’ models. Other interactive forms of presentation are also already available, for example in the realm of computer gaming, however the transfer and application of game engines to an architectural environment has not yet been explored in any depth. This paper looks at how “new media” can be used as a means of communicating architectonic information without simply emulating an already available traditional means of representation. We discuss the process of learning how “new media” (the computer as a multi media) can be used as a tool for the analysis and reconstruction of architecture. Using Mies van der Rohe’s unrealised project for a brick country house as a basis, a project was devised which communicates valuable design and analysis skills and also allowed us to explore the use of “new media” and to draw conclusions for teaching and research as well as to critically assess the opportunities, limitations and risks involved.

summary Activities in the building industry in Germany concentrate increasingly on a combination of renovation and new-build. A look at current computer aided applications reveals a serious lack of IT support for the whole architectural design process in and within existing buildings (e.g. building surveying, designing on site and the preparation of information for further use in later planning stages). An ongoing interdisciplinary research project undertaken jointly by the faculty of media and the faculty of architecture is investigating methods and techniques for the computer-aided support of the design process in and within existing buildings. The goal is to develop a hardware and software concept for a “design-toolbox” based on SAR (spatial augmented reality) and to implement aspects of this as prototypes. This paper describes the goals of the “Spatial Augmented Reality for Architecture” project and discusses possible fields of application for SAR for supporting the design process in existing buildings from a user’s perspective. This paper presents the initial results of the project, the development of a cave-like hardware and software concept called “low-cost projection in room corners” and the description of the core concept based on a client-server architecture. The project is funded by the “German Research Foundation (DFG)”.

title High-precision application of GPS in the field of real-time equipment positioning
source Automation in Construction 9 (3) (2000) pp. 299-314
summary In the frame of its research concerning real-time positioning and control of road construction equipment, the Laboratoire Central des Ponts et Chaussées, has carried out in 1996 a study to know more about the actual vertical accuracy that a real-time kinematic (RTK) global positioning system (GPS) sensor could reach, under work site conditions. This study has widely used the dedicated testing facility called SESSYL, built to perform high-accuracy and real-time evaluation tests on positioning systems. It has been performed in collaboration with the French road contractor COLAS and the Ecole Supérieure des Géomètres et Topographes (ESGT). First, there is the proposed adapted geodetic transformation procedure, compatible with the high accuracy requirements. Then, the main results of a special SESSYL tests program are presented, where the impacts of several influencing parameters on the vertical accuracy have been carefully examined. The core part of the paper is the analysis of the typical RTK GPS set of data, from which we have tried to extract two different components: a high-frequency noise, rather easy to filter, and a low-frequency bias. This bias, given its good repeatability, can be modelled and used in prediction to improve in real-time the raw accuracy of the data. As a full-scale validation of our study, a site experiment is finally described, carried out this time on a real piece of equipment (an asphalt paver) during real roadwork.

summary This paper is about the "Computer Integrated Road Construction" (CIRC) project, which is a Brite-EuRam III funded project, lasting 1997–1999, aiming at introducing a new generation of control and monitoring tools for road pavements construction. These new tools are designed to bring on the sites significant improvements by creating a digital link between design office and job site. The first part of the paper describes the background of the project, which gathers seven European partners from five different countries, and gives the objectives of the project, in general and for each of the two targeted products: one for the compactors (CIRCOM) and one for the asphalt pavers (CIRPAV). Then, the two prototypes are described, each of them being broken down into three main sub-systems: the ground sub-system (GSS), the on-board sub-system (OB) and the positioning sub-system (POS). The expected benefits for the different users are also presented and quantified. The central part of the paper is devoted to the main technical innovations that have been developed in the frame of the project: universal vector database for road equipment guidance, multi-machine functionalities of CIRCOM and the two positioning systems which are actually the technological keys of the systems. Finally, the state of progress of the developments of the two CIRC products and the first commercial success achieved in parallel are presented.

summary The first part of the paper gives a definition of positioning in the context of road work sites and stresses the advantages offered by the new generation of positioning systems. A logical classification of these systems is also proposed. The `global positioning system' (GPS) technique, as one of the most promising techniques, is detailed. The main point of the paper is the presentation of a new test facility for positioning systems which has been set up at the `Laboratoire Central des Ponts et Chaussées' (Central Laboratory of Roads and Bridges). First, its principle is described, based on the re-construction of a 6D reference trajectory to which the measurements of the system in test are compared. Then, the operation of the facility and the post-treatment software which has been specially developed for it are described. Finally, the results of some recent studies are given, results which would have been hard to obtain without using the SESSYL facility. During the first study, the facility was used to establish an accurate time-model of the vertical error and this model allowed us to propose an innovative method for improving the vertical accuracy. During the second study, SESSYL proved its capability of differentiating several state-of-the-art GPS receivers of the same category.

source Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 243–252
summary This paper is an account of the façade rationalisation strategy developed at Gehry Technologies for mitigating the tradeoffs between project constructability and the aesthetic implications of arranging flat panels over a complex surface. The strategy outlined was developed as the result of the digital building delivery of the Museo Soumaya façade in Mexico City designed by Fernando Romero LAR. This report documents the development process of a method for obtaining relevant construction information flows enabling the assembly of the façade system by a third-party sub-contractor in support of the façade system coordination. This report concludes on a method using bespoke software for extending the parametric modelling system Digital Project™ in the design support role of obtaining an aesthetically pleasing arrangement of flat hexagonal panels over a freeform surface.

title Are European cities becoming similar?
source CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary The paper discusses city specific development patterns to overcome todays transport problems. The results are based on recent andongoing research activities at TUW-IVV and ITS. At previous CORP-conferences, we presented the basics and the development of aplanning support tool to find optimal policy packages in urban transport and land use (Emberger, 1998), (Pfaffenbichler, Emberger, 2001). The core of this planning support tool is a dynamic land use and transport interaction model. This model, which we refer to as Sketch Planning Model (SPM), is embedded into an appraisal and optimisation framework. The SPM and this framework were developed in the recently finished European Union funded research project PROSPECTS1. Case studies with this planning supporttool were performed within PROSPECTS for the cities Edinburgh, Helsinki, Madrid, Oslo, Stockholm and Vienna. These cities are principally comparable in regards of their status (capitals and major business and education centres), but different in their size, population density, transport system etc. A set of policy instruments like public transport improvements, car traffic restrictions, and infrastructure provision was available to formulate strategies to reduce negative impacts of transport and to increase welfare. The overall objective was a sustainable development of the city. Although the instruments and the goals are similar in all investigatedcites, different solutions were adequate. The solutions vary in regard of spatial implementation, implementation time and level of implementation. The paper will highlight some reasons for the different development paths of the cities. As well the comparison of the do nothing scenario as the comparison of the most feasible policy strategies shows that European cities are different, need different solutions for their problems and will stay different in the future.

summary Concepts and ideas take shape in the head. Human beings think by relying on visual forms, they connect ideas and thoughts with images. Especially when we are dealing with complex processes, visualizations have always helped to increase our understanding of contents, to facilitate communication and thus to support cooperation. Communication and planning are not possible without real or imagined pictures or, as we prefer to say, images.This easily explains why computer-aided visualizations today are among the standard instruments in the field of construction and planning.

summary People are aware of objects in physical spaces to which they may act responsively. We are interested in human behavioral changes in the presence of reactive displays in shared environments. In a limited 2-week field study, using plants (both natural and artificial) as reactive displays, we observed human trash disposal/recycling behavior. We found that there is a significant increase in recycling (p=0.08) when there are reactive display with natural plants. We also noticed increase in recycling with displays with artificial plants. These findings suggest that people can and do alter their behavior in shared environments, and that such behavioral changes can be effected by the use of reactive/responsive information displays.

title Augmented Reality-Based Education and Fire Protection for Traditional Korean Buildings
source International Journal of Architectural Computing vol. 8 - no. 1, 75-91
summary This study examines an application of Augmented Reality technology (AR) for Korean Cultural Traditional Buildings, specifically, the Namdaemun Gate, "National Treasure No 1" of the Republic of Korea. Unfortunately, in February 2008, the Namdaemun Gate burned down, despite the efforts of many firemen, as the main difficulty was getting the fire under control without any structural knowledge of the wooden building. Hence, with the great advances in digital technology, an application of virtual technical information to traditional buildings is needed, and the new technology of AR offers many such advantages for digital architectural design and construction fields. While AR is already being considered as new design approach for architecture, outdoor AR is another practical application that can take advantage of new wearable computer equipment (Head-mounted display also know as HMD, position and orientation sensors, and mobile computing) to superimpose virtual graphics of traditional buildings (in this case, Namdaemun Gate) in a real outdoor scene. Plus, outdoor AR also allows the user to move freely around and inside a 3D virtual construction, thereby offering important training opportunities, for example, specific structural information in the case of firemen and mission planning in the case of a real-life emergency. In this example, the proposed outdoor AR system is expected to provide important educational information on traditional wooden building for architects, archaeologists, and engineers, while also assisting firemen to protect such special buildings.

summary Collective Design seeks to explore how new forms of Collective Intelligence, arising from the web, allows mass participation in design. Regarding design we have a wellestablished grounding for understanding how design works through the use of representations. Likewise, collective intelligence via certain crowdsourcing examples has demonstrated that a diverse crowd can trump ability groups, when the conditions are right. In the literature, crowdsourcing is the leading lens bridging design with collective intelligence. However in crowdsourcing design there is less focus on the role of shared representations, subsequently any collective diversity is mitigated by the models that govern the extraction of this intelligence. We propose that more effective design in collective intelligence lies in the crowd’s ability to generate meaningful contributions via the content of shared representations. In order to investigate this, the current paper examines data collected from a pilot study in which a representationally rich online collaborative presentation tool is used to provide a shared design space. The analysis presented applies our previously established semiotic framework to identify potential patterns in the meaningful communication of image based design information.

title Kinetic Hybrid Structure Development and Simulation
source International Journal of Architectural Computing vol. 10 - no. 1, 67-86
summary Supported through technological advances, the concept of kinetic architecture is internationally increasingly acknowledged in the past years in the development of adaptable buildings as to differing functional requirements, or external loading conditions. Most decisive factor is the structure in terms of materials and geometrical configurations, and the control system integrated within. Based on general principles of tensegrity structures, a hybrid system has been developed that consists of continuous hinge connected compression members, strengthened by an internal system of struts and continuous cable diagonals with closed loop. The kinetic mechanism is achieved through alteration of the cables length and the respective relative inclination of any adjacent compression members. In this way the transformability of the system arises primarily from the inherent integrative composition and dual capabilities of its members. Following the construction design of the prototype structure, the interactive development, as regards geometric properties and structural configurations, is presented analytically, as based on a parametric-associative design approach applied. Along this line, the specific syntax of structural development and simulation through parametric design is suggested to support in real terms the control design of the innovative structure in an integrated interactive context.

summary The quality of computer generated images of three-dimensional scenes depends on the shading technique used to paint the objects on the cathode-ray tube screen. The shading algorithm itself depends in part on the method for modeling the object, which also determines the hidden surface algorithm. The various methods of object modeling, shading, and hidden surface removal are thus strongly interconnected. Several shading techniques corresponding to different methods of object modeling and the related hidden surface algorithms are presented here. Human visual perception and the fundamental laws of optics are considered in the development of a shading rule that provides better quality and increased realism in generated images

summary Generative design system develops the purpose that is can generate a large number of design plans. Generative design system can let designer unceasingly explore the new design plans. At present generative design system, they all only have one kind of generative mechanism. Therefore, one can’t provide enough feasibility for designer to explore new plans. So, in this paper, we propose a Co-Generative Form System (COgenForm). COgenForm is a 3D form exploration system that invokes two set of generative mechanisms. This system used co-evolutional characteristics to build the steps and framework of co-generative design process. This system includes two groups of generative mechanisms and these will evolve with each other. Using this system, the form exploration and generation process can be more dynamic and more alternatives.

It is based on previous studies on architecture, art and technology on modernity and its development, as well as studies about scale in architectural design. In despite of the fact that scale can be technically considered indifferent for computer aided design, I wish to discuss how digital tools intercede in the process of clipping that selecting a specific scale eventually implies, sustaining that for architectural design, the concept of scale has to do both with representation and knowledge of reality.

The program enables students to compose structures and to experiment interactively the effects of different geometry and load configurations. It tries to identify the proposed structure and controls its stability. Upon request of the student, it also processes displacements, internal forces (moments, shear forces, etc.) and reaction forces on supports. The students can then visualise the desired information by interacting directly with the structure or its members of interest. We present different methods with which students can visualise the results of their actions and discuss their implications in the educational context.

summary This paper aims to connect a reading of Francisco Goya’s painting Vuelo de Brujo with Marco Frascari’s metaphorical exploration of the idea of ‘monstrosity’ in architecture in Monsters of Architecture (1991). It also seeks to connect these works to contemporary forms of digital monstrosity and the proposition that the existential anxiety explored within current digital representations of the monstrous have both their basis in the technical apparatus within which they are created, and current thinking on material realism in ontology. Given the emergence of complex forms of ‘life’ within Cellular Automata studies and the speculations regarding digital ontology stemming from Stephen Wolfram’s New Kind of Science, the paper also asks what the consequences of large-scale expansions of these capabilities will entail in a post-Singularity scenario.

summary This paper investigates the relationships between conventional modes of architectural design, those represented through and mediated by Cartesian schema, and the radical organization of spatial experience available through the use of NURBS modelling. This is examined particularly through a study of how game engine software and the appropriate editors are able to accommodate the properties of both. Within this software the first-person view attempts to provide a normalised experience of the VR environment (usually a game), yet there is significant scope for experiencing radically ‘other’ spatial and topological presences. Whilst considerable work has been done in the use of participatory digital spaces, there is the opportunity for examining the manner in which a highly stylised medium such as Unreal Tournament can productively assist the architectural design process.

source Computer-Aided Design, Vol. 28 (9) (1996) pp. 699-706
summary An algorithm for approximate skinning through cross-sectionalNURBS curves is presented. The method eliminates the problem of dealing with huge amounts of control points obtained during the curvecompatability process. It also allows the designer to specify large numbers of cross-sections and approximately fit a smooth surface to these curves to any given tolerance. Depending on the tolerances used, up to99% of the control points can be eliminated.

summary The paper concerns the issue of constructing flat vaults from elements topologically interlocking inspired by the Abeille blocks. One of the new ideas that are presented is constructing the vaults in an order opposite to the one considered untill now. The problem of static response on the thrust force, significant for flat vaults, is usually solved by the use of the perimeter frame, added only after arranging all the elements of the vault. The paper presents how to arrange the vault inside a previously made frame thanks to application of special components divided into parts, which are inserted at the end and play the same role as a keystone in a stone arch. The other new concept is shaping vaults based on equilateral triangles and regular hexagons, from hexagonal, romboidal and triangular elements shaped and arranged in a manner similar to the one used for shaping square vaults. The last innovative concept presented in a paper concerns shaping the perimeter frame from the components providing stiffness of the frame only due to topological interlocking. All presented ideas have been analised purely at a geometric level.

summary The emergence of a data space (Big Data and IoT) and, with it, the proliferation of communication means, led many scholars to describe the city through a series of concepts like the informational city, the intelligent city or the cybercity, all of them being characterized by a strong networked consciousness (Castells, Graham, Boyer). The hypothesis of this paper is that game methodology is now gaining momentum and can act as enabler of smarter communities by an increasing access to data infrastructures. This is why the city can be seen as a series of connected playgrounds where interactive tools can support citizen engagement and decision making processes. It does so by going through relevant theoretical background on gamification in the urban context and best practices, to finally describe two student projects developed at CHORA Conscious City, TU Berlin. The two projects are experimental and explore the capabilities of interactive tools in order to support planning processes.

title Toolspaces and Glances: Storing, Accessing, and Retrieving Objects in 3D Desktop Applications
source Proceedings of the Symposium on Interactive 3D Graphics 1999. pp. 163-168
summary Users of 3D desktop applications perform tasks that require accessing data storage, moving objects, and navigation. These operations are typically performed using 2D GUI elements or 3D widgets. We wish to focus on interaction with 3D widgets directly in the 3D world, rather than forcing our users to repeatedly switch contexts between 2D and 3D. However, the use of 3D widgets requires a mechanism for storing, accessing, and retrieving these widgets. In this paper we present toolspaces and glances to provide this capability for 3D widgets and other objects in interactive 3D worlds. Toolspaces are storage spaces attached to the user's virtual body; objects placed in these spaces are always accessible yet out of the user's view until needed. Users access these toolspaces to store and retrieve objects through a type of lightweight and ephemeral navigation we call glances.

summary This thesis research presents an integrated workflow for the design and fabrication of large-scale architectural envelopes using swarms of drones and inflatable structures as formworks. The work lies at the intersection of architecture, biology and robotics, incorporating generative design with digital fabrication techniques. The proposed approach aims to investigate the tectonic potential of computational systems which encode behavioral strategies inside an agent-based model. It is from local interactions taking place at the micro-scale of complex systems that a new set of architectural tendencies seem to emerge. The authors focused on the strategies developed by colonies of social spiders during the construction of three-dimensional webs. Their communication system and the characteristics of the material structure have been then modelled and translated in a digital environment. A physical fabrication process, in which the simulated agents become drones in a real world environment, was concurrently developed. The goal was to investigate the architectural possibilities given by an autonomous aerial machine depositing fibrous material over inflatable formworks and its potential usefulness in specific sites where overall conditions don't allow traditional construction techniques.

summary The building of a city model of Adelaide, Australia, has been as much determined by stakeholder enthusiasm and administrative context as technical questions. The present state of the model is comprehensive in area but exists with parts at very different levels of detail, determined by the various motivations behind their creation. The paper describes some examples of the use of sections of the model as a basis for student design projects, as a basis for City planning department-initiated explorations of development proposals, as a basis for the negotiation of acceptable development proposal strategies between City planners and the public, and as a means of presenting the implications of development proposals to City councillors who are members of the Planning Committee.

summary An overview of the research activities of a university simulation laboratory is presented. The mission of the laboratory is to anticipate the design and to support the evaluation process of urban design projects from a perceptual viewpoint through the use of digital and physical models. We have research and educational purposes. Founded five years ago, the laboratory has implemented different simulation tools, often combining existing techniques and finding new applications of existing ones. In particular, we focused our interest on visual perception tools, investigating the use of physical models and digital ones, and combining them in different ways in order to enhance the experience offered by the perceptual simulation.

title The Urban Simulation and Projects Evaluation Laboratory at the Politecnico di Milano: An Educational and Research Facility
source Projecting Spaces [Proceedings of the 9th European Architectural Endoscopy Association Conference / ISBN 978-3-942411-31-8 ], pp. 115-120
summary At the beginning of 2007 an Italian Urban Simulation Laboratory was founded at the Politecnico di Milano. The laboratory, coordinated by prof. Fausto Curti, has been developed thanks to the one year presence of the visiting professor Peter Bosselmann, director of the Environmental Simulation Laboratory at the University of California at Berkeley. The laboratory has an interdisciplinary approach and a threefold mission: experiment, using the laboratory setting to study urban projects at different scales; communicate, aiding public communication by making urban projects understandable to everyone; integrate and innovate, working on different kind of simulations techniques in an integrated way. In its initial experience the laboratory is primarily a didactic and research facility. Students can join the work and participate actively to the research. Until now about 40 students have worked with us, more than a half were foreign students from all over the world. The majority of the students did an internship of about 150 (three-year degree) or 300 (master degree) hours and some of them have continued working after this period developing a thesis. At the moment the case study, used as a pilot research, is about the Porta Nuova project at the Garibaldi- Repubblica area in Milan. The 300.000 mq of the total area and its well served central position make this place strategic for Milan. In this area the adopted urban transformation plan is creating a new business center that affects redevelopment projects, new infrastructures, and a park. The overall project will overhanging the surroundings city center with some of the highest buildings of its skyline. The importance of the site and the dimension of the project make this case significant to test the use of simulation for supporting evaluations about morphological aspects, comfort conditions, visual impacts, and other aspects that directly influence the quality of the new urban spaces. We are now applying different simulation methodologies in order to better understand the peculiar usefulness of each kind as a tool to support evaluation. As any kind has its own limits we work with different typologies at the same time. We are working with 1:500 scale physical model of a 1 km square of the area and different kind of static and dynamic simulations. We developed, with an external office, a micro-car to move a micro-camera in the maquette. We use this equipment to better explain the project implications to the students by producing subjective shot videos or showing a walk in real-time. To reproduce in a better way some relevant walks through the transformed site we have also produced some videos made of a superimposition of the real existing context and the virtual projects. To do this we used a rendered video of the project superimposed to the filmed promenade of the today condition, previously recorded using steadycam. A lot of static simulations has been employed to better understand the new city configuration from some representative points of view, as for example the roof of the Duomo cathedral. We are now developing some other kinds of analysis such as shadows impact; this is done by using a 1:1000 scale maquette in the Heliodon, but also with some digital tools. In the next future a work with the wind tunnel will help to understand some other comfort implications of the project at the micro-urban scale. The multilayer approach is the main aim of the laboratory and is an important tool to clarify the multidimensional project impacts to the students. In this way the laboratory can be a learning tool, it can stimulate the project process and support decision-making while improving the knowledge about the correct use of simulations for evaluating the cumulative implications of the proposed urban processes.

summary The aim of this study is to develop a novel toolkit for co-design with community stakeholders based on the use of digital interactive simulations. The toolkit is composed of a variety of tools, with a specific focus on emergent technologies. We argue that tools, especially interactive and immersive ones, can be efficiently applied for enabling citizen engagement and supporting place-making processes thanks to the natural interaction and intuitive understanding of design schemes. The occasion for testing a co-design process and simulation techniques was the redesign of a shared public space, an initiative promoted by the project Citt? Studi Campus Sostenibile, a sustainable campus program supported by the Politecnico di Milano and the Universit? degli Studi di Milano.

summary This paper presents a methodology for the integration of fabrication constraints within the architectural design process through custom written algorithms for fabrication. The method enables the translation from three-dimensional geometry, or algorithmically produced data, into appropriately formatted machine codes for direct CNC fabrication within a single CAD modeling environment. This process is traditionally one-way with part files translated via dedicated machine programming software (CAM). By integrating the toolpath creation into the design package, with an open framework, the translation from part to machine code can be automated, parametrically driven by the generative algorithms or explicitly modeled by the user. This integrated approach opens the possibility for direct and instantaneous feedback between fabrication constraints and design intent. The potentials of the method are shown by discussing the computational workflow and process integration of a diverse set of fabrication techniques in conjunction with a KUKA 7-Axis Industrial Robot. Two-dimensional knife-cutting, large-scale additive fabrication (foam deposition), robot-mounted hot-wire cutting, and robot-assisted rod-bending are each briefly described. The productive value of this research is that it opens the possibility of a much stronger network of feedback relations between formational design processes and material and fabrication concerns.

summary New operation frameworks and user-oriented design methods are needed to make better use of new innovative technologies within smart city contexts. This paper addresses the design and research of intelligent lighting and user-oriented services for smart city environments. It presents the problem setting and research and development methods of the SenCity project. The project will pilot smart lighting solutions in six Finnish cities in different kinds of urban environments. In the pilots, the target is to employ lighting infrastructure as a service platform - an Internet of Things backbone - in the intelligent city. Together, separate pilots in different cities around Finland will create a living lab ecosystem for developing and testing innovative solutions. The specific objective of this paper is to present the concept of a platform as defined and applied in SenCity project. The presented framework forms an operational model for creating intelligent lighting and digital services in smart cities by integrating relevant technologies, users' needs, and business into an interactive system. In the paper, the framework is applied to a selection of pilot cases with specific themes to introduce its usability in real world implementations.

summary This proposed paper presents the results of a real world demo of adaptive urban lighting in a pedestrian oriented street in the core centre of a northern city of 65°01’ latitude, Oulu, Finland. The case project – LightStories (Valotarina) – explores the methods to enable city dwellers to participate in the design of public urban lighting, as well as interaction and communication through urban lighting. It applies a web-based design tool which offers city dwellers the possibility to design one hour long light animations to be displayed along a pedestrian oriented street. In addition to describing the design and development process of the lighting system and the participatory design tools used in this case, the paper presents general discussion about the process and tools, and also about the role of algorithm aided methods in enabling the user participation in lighting design with the tool.

title Situation Analysis of Design Tasks for CAD Systems
source Behaviour and Information Technology 1989 v.8 n.3 p.191-206
summary There has been little empirical research on the human aspects of CAD systems. In this paper observations on the analyses of designer activities are presented, by using a systems design approach. The paper concentrates on situation analysis and subsequent allocation of system tasks. A situation analysis was carried out in two design departments. The analysis consisted of a formal system description and a reconstruction interview. During the interview the previous week's activities were reconstructed with the help of photographs of the drawing board and protocols completed by design draughtspersons. This procedure was used for six design projects. In this study the technique of the reconstruction interview proved to be very useful and informative, and enabled three general conclusions to be made. First, designers liked the initial design phase and their responsibility for the final result. Second, they disliked the activities associated with drawing as well as the project documentation phase. Third, they preferred to work with two or more drawings on the drawing board. A number of frequent tasks could be identified, for example, large scale manipulation within and between drawings. In the final section, an example of a global allocation of system tasks for the design of a CAD system is given.

summary Information Visualization is a discipline implemented on interfaces which use one sense to understand the ideas developed: sight. However, there are physical interfaces that allow users to interpret the data, either through sound or touch. The objective of this paper is to discuss the preliminary results of the research project that frames this paper, as a work in progress.

summary This paper presents an interdisciplinary work done at the Museum Oteiza near Pamplona, Spain during 2012 and 2013. The main goal is the use of low cost devices that allows natural interaction, Virtual and Augmented Realities to get the general public closer to the works and concepts of Oteiza through interactive serious games. The most difficult Oteiza’s concepts to understand are those related with the empty space or with time & space. We propose three different activities, shaped as serious game, that use the whole body to interact and play with these concepts. The result is a facility that has been installed at the entrance of the Museum and that can be used for free, before or after a visit to the museum. These activities were presented to 4 experts in Oteiza and the results are discussed. In addition, we gathered more comments after several groups of children tried the application in the museum.

title The Grammar of Crystallographic Expression
source ACADIA // 2016: POSTHUMAN FRONTIERS: Data, Designers, and Cognitive Machines [Proceedings of the 36th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-77095-5] Ann Arbor 27-29 October, 2016, pp. 236-243
summary This paper stems from a research collaboration which brings together two disciplines at different ends of the scale spectrum: crystallography and architecture. The science of crystallography demonstrates that the properties of crystalline materials are a function of atomic/molecular interactions and arrangements at the atomic level—i.e., functions of the form and structure of the material. Some of these nano-geometries are frameworks with special characteristics, such as uni-directional porosity, multi-directional porosity, and varied combinations of flexibility and strength. This paper posits that the symmetry operations implicit in these materials can be regarded as a spatial grammar in the design of objects, spaces, and environments. The aim is to allow designers and architects to access the wealth of structural information that is now accumulated in crystallographic databases as well as the spatial symmetry logics utilized in crystallography to describe molecular arrangements. To enable this process, a bespoke software application has been developed as a tool-path to allow for interoperability between crystallographic datasets and CAD-based modelling systems. The application embeds the descriptive logic and generative principles of crystallographic symmetry. Using this software, the project, inter alia, produces results related to a class of geometrical surfaces called Triply Periodic Minimal (TPM) surfaces. In addition to digital iterations, a physical prototype of one such surface called the gyroid was constructed to test potential applications in design. The paper describes the development of these results and the conclusions derived from the first stage of user testing.

title Design Evaluation Based on Virtual Representation of Spaces
source Design and Representation [ACADIA ‘97 Conference Proceedings / ISBN 1-880250-06-3] Cincinatti, Ohio (USA) 3-5 October 1997, pp. 111-120
summary When spaces are evaluated, clients and architects often discuss design proposals by looking down at scale models. This overhead perspective forces viewers to imagine themselves looking and moving about within the model. Misperceptions may well result from such a point of view. With the advancement in virtual reality (VR) technology, and with its rising popularity in architecture, it is becoming plausible to consider using VR to evaluate design projects.

The projects presented here are of three types: (1.) The first project compares people's evaluation of several slightly modified virtual models of a space. (2.) The second project compares how people evaluate a foam core model of a space to how they evaluate a virtual representation of the same space (3.) The third project compares people's evaluation of a real space to that of a virtual representation of this space. //

The wide range of results presented provides one argument in support of using VR simulations to study spaces and how they are perceived. For example, results shows that a virtual window serves to alleviate perceived crowding and that added furniture serves to make a virtual room feel slightly larger and less constraining. However, problems did emerge with using virtual reality simulations to gain information about peoples' behavioral reactions to a space. Thus, not all circumstances under which VR representations are used creates valid results. Differences appear to be in the type of evaluations measured (e.g. dimensional versus behavioral). More research is needed to clarify this issue.

Taking Weiser and Brown (1996) concepts of Ubiquitous Computing and Calm Technology as a starting point, we delimit ambient information systems as those that can be monitored without requiring the focus of our attention. Using the theoretical framework from Cognitive Psychology, we propose an evaluation model to analyze ambient information systems, considering the attentional mechanisms involved in their use. As a conclusion, we outline a set of parameters to be considered during the design of ambient information systems.

summary We will analyze a pedagogic exercise that joined together both the Informatics and Morphology Courses, required in the second year of Architecture School. The objective of the analysis is to explore the possibilities of the computer as a tool for design, and also to contribute some ideas for planning, curriculum development, and the necessary training to introduce the use of computer graphics in the Architecture School. We based our analysis on some preliminary hypotheses: (1) Students must learn to use digital models with a certain degree of simultaneity with learning design and the other techniques used to develop models. (2) Professors of Design, Representation, and Morphology are main actors in this learning process; they do not have to become experts in informatics, but have some understanding of the topic. (3) Many universities and professional associations are offering students and professionals courses based in the use of programs, instead of addressing their real needs.

The process of Design considers different dimensions, including people, technology and context, in which the prototype has a distinct role. On the way to synthesis, early solutions speculate, on a descriptive and conceptual way, about possible solutions to a given project in an early state. The importance of a clear communication between all stakeholders in the process to refine details is also studied.

summary This paper, introduces a cybernetic approach to digital design and fabrication by embracing aspects of embodied interaction, behavior and communication between designers and machines. To do so, it proposes the use of body gestures, digital/tangible interfaces and Artificial Intelligence to create a more reciprocal way of making. The goal is to present a model of designing and making as a ‘conversation’ instead a mere dialog from creator to executor of a predefined plan to represent an idea. In other words, this paper proposes a platform for interaction between two antithetical worlds—one binary/deterministic and the other perceptual/ambiguous—by focusing in the exploratory aspects of design and embracing aspects of improvisation, ambiguity, imprecision and discovery in the development of an idea.

summary Design is “something that we do” that is related to our unique human condition as creative individuals, so as “making” is related to how we manifest and impress that uniqueness into our surrounding environment. As designers, the way we impress our ideas into the material world is tightly connected to a ‘continuous creative performance’ and with concepts often missing in digital design and fabrication techniques –yet present in analog processes - such as ambiguity, improvisation and imprecision. In this paper, a model of human-machine interaction is proposed, that seeks to transcend the ‘hylomorphic’ model imperative in today’s digital architectural design practice to a more performative and reciprocal form of computational making. By using body gestures and imbuing fabrication machines with behaviour, the research seeks to embrace the concept of ‘performance and error’ as promoters of creativity and cognition about the things we create, installing human as the bond of the interrelations between designing and making.

summary In the case of designers, architects and arts, tools are part of a repertoire of cognitive, symbolic, and semiotic artifacts with which each explores and learn about design problems. Nonetheless, when using digital fabrication tools, a dichotomy between what is ideated and what is made appears as an evident problem since many of the perceptual aspects of sensing and thinking about new things in the making are neglected. It is argued that this establishes a dichotomy between what is ideated and what is executed as an outcome from that idea. How designers can think, learn and augment their creativity by using digital tools in a more relational, exploratory, interactive and creative way? Furthermore, how can we teach design using contemporary fabrication tools beyond its representational capabilities? This paper explores the richness of using digital fabrication tools through the lens of shapes grammars as a design paradigm in order to extend computational making including digital fabrication tools, gestures and material behavior as crucial actors of the design process. Through the use of discrete heuristics - that is, the elaboration of deictic rules for computation with physical objects, materials and fabrication tools in a precise yet perceptual way- this paper shows experiments inside a third year design studio to overcome the hylomorphism present in the digital design and make dichotomy.

summary Evolution and innovation in architecture are intensely related to the rise and developments of technology. Within this context, it is possible to recognize how in recent decades this milieu has fostered the development of new methodologies for urban design and architectural practice, as is, for example, the Parameterization. This paper is focused on the subject of Parametric Urbanism: discussing / questioning the emergence of this new architectural methodology; addressing the factors that contributed to its appearance; and seeking to understand whether the parametric approach has benefits and whether it may or may not be a solution or of assistance to urban planning. The paper provides a brief literature review focused on parametric urbanism and then it presents a practical case study of parametric urbanism: an Urban Plan in Beijing, developed in an academic context, at the University École Polytechnique Fédérale de Lausanne in 2012. Having as base diverse examples of parametric urbanism, it is tried to identify/justify decisions defining principles and application guidance for this project. The conclusion presents the final considerations based on opposing the case study with the theoretical approach, seeking to clarify whether this new kind of urban design methodology, Parametric Urbanism, is or not viable.

summary Computer-Aided Architectural Design Futures was conceived late one evening in the bar of the Metropole Hotel in Brighton, UK. Those present - veterans of a hundred and one CAD conferences - were bemoaning the degree to which big business was taking over the conference scene: exhibiting was replacing conferring, selling was replacing thinking, products were replacing ideas. Wouldn't it be nice, we agreed, to get back to an 'academic' conference which would take stock of current developments in CAAD and attempt to anticipate the direction of future developments and their impact on architectural practice, on the building industry and on the quality of the built environment? Four major themes are explored in CAAD Futures: (1) Systematic design; (2) Drawing and visualization; (3) Artificial intelligence and knowledge engineering; (4) Implications for practice. // Stimulus papers on these four themes were circulated prior to the Conference, and the conference papers themselves elaborated the issues raised in the stimulus papers in such a way as to encourage discussion. The resulting book, we believe, will be a major reference text for students, researchers and practitioners.

summary This paper demonstrates the process of generation of physical paper models from digital models of curved surfaces through the digital technique for approximately flattening. A collection of these models, based on works of architecture, is being produced as a didactic activity within a discipline of graphic and digital geometry in the curriculum of architecture. The study allowed the identification of parameters to improve the process of generating such models and recognize the kirigami technique as an alternative for the representation of non-developable rectilinearsurfaces, previously not included for the generation of physical models in the didactic activities in question.

title Objetos de Aprendizagem para Promover a Apreensão e Criação da Forma Arquitetônica
source 5° Congresso Nacional de Ambientes Hipermídia para Aprendizagem, UCPel e UFPel, Pelotas, Brasil
summary Em estágios iniciais de ensino/aprendizagem do projeto de arquitetura existe um interesse de que os estudantes adquiram um vocabulário geométrico preliminar que os auxilie a compreender a forma arquitetônica. Atividades apoiadas em análises de casos de arquitetura tradicionalmente vêm contribuindo com esse propósito. Entretanto, identificam-se novas abordagens, como as apresentadas pela gramática da forma, que incorporam parâmetros sob o ponto de vista geométrico que facilitam a sistematização da atividade de análise de composições formais e arquitetônicas, tais como o vocabulário e as regras empregados. Este trabalho se ocupa em produzir materiais didáticos que reúnam estruturas de saber advindas de duas abordagens de caracterização da forma: por um lado, a representação gráfica digital observando-se o seu potencial para aprofundar os conhecimentos geométricos, e, por outro, saberes da teoria da Gramática da Forma, como maneira de ampliar e fundamentar a atividade de análise, de representação da forma arquitetônica e principalmente de potencializar processos criativos de composições formais. Apoiando-se na abordagem da metacognição, considera-se que os materiais resultantes desencadeiam processos reflexivos sobre a configuração da forma arquitetônica, ativando os conhecimentos prévios dos estudantes para projetar, contribuindo ao propósito de ampliação do vocabulário e repertório geométrico para os estágios iniciais da prática projetual. A atividade de identificação de estruturas de saber, no âmbito deste estudo, demonstra-se também como estratégia para a aproximação ao conceito de objetos de aprendizagem, quanto aos aspectos de granularidade.

title IDENTIFICAÇÃO DE ESTRUTURAS DE SABER IMPLÍCITAS EM MATERIAIS DIDÁTICOS PARA A DELIMITAÇÃO DE UMA TAXONOMIA DE DOMÍNIO
source 1° Congresso Internacional de Educação a Distância da UFPel, Pelotas, Brasil
summary O aumento da produção de materiais didáticos em formato digital configura a necessidade de disponibilizar sistemas de catalogação para facilitar mecanismos de busca e recuperação dos materiais gerados. Em contextos de educação a distância, principalmente quando se trabalha com o conceito de objetos de aprendizagem, este problema pode adquirir maiores proporções, no sentido de que um mesmo material pode se decompor em várias partes, cada uma delas devendo ser indexada e ainda demonstrar as conexões inicialmente determinadas. Frente a isto, este trabalho experimenta configurar uma metodologia para a identificação de uma taxonomia que abarque um conhecimento específico, capaz de descrever e conectar objetos de aprendizagem, em diferentes níveis de granularidade e advindos de diversas abordagens. A metodologia se apóia em análises de materiais didáticos, que tratem de temas convergentes, a partir da abordagem de estruturas de saber. Através de mapas conceituais são explicitadas as estruturas de cada material, destacando-se palavras chaves capazes de delimitar uma taxonomia que no conjunto dos materiais pode ser ampliada e representar uma ampla estrutura capaz de responder às questões específicas do saber tratado. Os resultados, ainda que parciais, delimitam uma rede conceitual que expressa tais materiais, e as suas interconexões, visando facilitar sua acessibilidade, na Internet, a partir da delimitação de uma taxonomia para o domínio do conhecimento tratado.

summary This work has a didactic approach in teaching digital graphic representation for Architectural Design. Seeks to identify structures to know that support geometric concepts employed in works of contemporary architecture. Faced with technological advances and the recent insertion of parametric design in offices and schools of architecture, the study also aims to support the recognition techniques parametric modeling related to such concepts. How explicit methodology to know structures are adopted, taxonomies and ontologies, we consider the potential of these structures to explain the treaty knowledge and facilitate the association of educational materials on the topic in online systems, supporting learning processes of the agents involved (students and teachers).

source SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary Geometric knowledge increases the memory of the architect, which is formed dynamically, from new experiences on the comprehension of shape. Such process suggests the acquisition of a specific vocabulary for describing shape. With the aim of recognizing a wide geometrical and architectural terminology, experimentation is performed. The present work also describes an architectural project which uses metadata characterized by the identification of knowledge structures composed of four approaches whose geometrical and architectonical focus are present. The proposed systematization, which denotes and delimits a specific vocabulary, is considered as being able to contribute to the re-indexing of formal frameworks through the dynamic process of memory constitution to the architecture design.

summary This paper describes a process of identifying a taxonomy for describing learning materials made available in the context of a Virtual Learning Environment for Architecture and Design and produced by partner groups coming from different institutions. Paying attention to the specificity of the knowledge structure conveyed in such materials, exemplified in the case study of the digital graphic representation material, the importance of seeking by different terminologies combining concepts, techniques and technologies involved in different approaches to the same subject was observed, by allowing to characterize the structure of the teaching material and, through relationships among its terms, identify the connection between other learning objects for architectural design.

summary Creating architectural form requires much more than a moment of inspiration; it requires understanding form in its whole structure. In teaching architecture aiming for the architectural design a group of strategies is needed to prepare students for the creative process. In this process it begins with issues such as the geometry allows the students redeem their prior knowledge. This paper compares, in two different contexts of the initial stages of architectural teaching process, the results of activities of digital graphic representation of architectural structures. These activities are supported by the analysis of shape grammar in promoting the learning process in a comprehensive manner such as suggested by Wertheimer.

summary Among the many possible ways of classifying the concept of “modelling”, Maldonado refers to “homologies” when structure but not shape and function are similar; “analogies” when structure and function are similar, but not shape; and “isomorphisms” when structure and shape are similar, but function may or may not be similar. Traditional artistic representation would basically fall into the category of isomorphisms, whilst analogous models are to be found mainly in activities such as magic, play or industry. Other ways of representing reality, such as architectural models or drawings, are also traditionally regarded as isomorphisms. In the course of the last century, this panorama has been altered somewhat by the post-industrial or second industrial revolution in computing and communications. Using mathematical algorithms, the computing tool has an enormous capacity to describe things of extremely diverse nature: from the shape of everyday objects to relatively complex human behaviours, these can all be described using the common language of bits. Alongside developments in computing, the world of communications has been providing us with increasingly advanced means of transmitting information, including sophisticated systems capable of emulating our own perceptions. This paper is intended as a contribution to the theoretical debate conducted over recent years on the considerable shift that has occurred in architectural representation techniques. The analysis that follows highlights a two-fold change in traditional representation techniques: on the one hand, a change in the nature of the model (as is discussed in this paper); and on the other, a modification of the interfaces or communication and perception mechanisms of the model. The conjunction of these two factors has led to the emergence of representation modes that can no longer be regarded simply as isomorphisms of reality. Insofar as virtual spaces have the capacity for us to move, to interact, in short to inhabit them, they should be regarded as “analogous models” of architectural space. In other words, there has been a shift away from representation modes based on illusion in favour of those based on simulation.

summary Brazilian construction industry's efficiency level is very low. Within the public administration sectors responsible for the construction of public facilities, this fact is amplified by the very nature of the laws regulating the public expenditures. Transparency and active public accountability are in its initial stages, creating misinformation and opportunities to corruption. Some public initiatives of adopting BIM (Building Information Model) for public construction projects are however taking place, seeking to revert this scenario. Corruption is one of the particular problems that are to be addressed for a efficient adoption of BIM in the public sectors. In addition to the traditional corruption-fighting tools, if we comprehend all the actors and processes that lead to the construction and operation of a public building as a whole complex system, where BIM is responsible for transparent flux of information, it can provide another layer of transparency, accountability and social control over the process.

source eCAADe Conference Proceedings/ Munich (Germany) 17-19 October 1991
summary As a rising number of schools of architecture have decided to extend their curriculum with the new subject CAAD (Computer Aided Architectural Design) the questions of how to organize the education is deeply affecting the concerned faculty members. Though the general education objectives differ with crossing the borders it is of high interest and at the same time extraordinarily valuable to achieve an exchange of experience in the methods of CAAD-education - thus giving new stimulus to the "aged" CAAD-teachers and encouraging the "newcomers". The submitted papers were coming from many countries and they are covering a variety of questions dealing with education and practice. Research topics are touched, because the research work of CAAD- teachers always has some influence on the educational work.

summary The educational outlines used by the German, and most other European schools of architecture, have certain differences in comparison to an American school. This is partly due to the different tasks each group has to fulfill. Our architects not only plan their projects in detail, but in many cases they have to supervise the site as well. Most importantly, they also check on all communications between those participating in the design process. Skills of architects leaving their schools and entering into practical life generally need further training. Since CAAD is becoming more and more involved in architectural design studios of various sizes, the development of skills in this area should be shifted towards the period of studies. Thus, schools and staffs have to react to meet the needs of the present facts.

source CAAD Instruction: The New Teaching of an Architect? [eCAADe Conference Proceedings] Barcelona (Spain) 12-14 November 1992, pp. 363-376
summary Today we can look back on several years of data processing support in architecture. When computer aided architectural design - CAAD - entered the field there was a lot of utter confusion in the beginning, a lot more than usually in other more technical application-fields of CAD. The architect is a very special CAD-user, as he is a very special member of all those other very analytical and scientific faculties around. There is a lot of tradition involved, tradition that has got its roots far back in medieval and classic periods and is rich of art and creativity and intuition. Mostly lots more of this than scientific analysis, exact research, and similar stuff. We could spot a large number of architects who would have been horrified when they are confronted with the analytic research of the very basic problem as how architects are designing - the methods, the procedures and the ways of thinking. And there CAAD was entering the architects' studios. No question that this caused a lot of trouble. CAD in architecture is a very provoking subject as the new tool is going to gain ground against the tradition of centuries of handmade architectural designs and drawings. And there we don't even touch the future aspects of the computer's architectural design support - what about the imminent threat of computer support in the holy domain of architectural creativity and intuition. What about the uneasy idea of CAAD in connection with artificial intelligence? The problem of CAAD-education has been largely neglected through a number of years. If there existed a certain horror looking at the mere idea of CAD-support in architecture, horror became to outrage, when university education was discussed. In our days we can stay a good deal more relaxed, when we speak of CAAD education - we not only got used to it, we are convinced, that the whole subject is of high importance.

summary Co-operation and/or collaboration is a vital aspect in planning. Many partners have to share information and have to react - if possible - without delay. In order to get support by computers combined with modern and recently immensely improved means of communication we have to explore, how we (should) communicate and what would be necessary to support this - may be in a different or modified process - by new media. It is obvious that this investigation will be a different one, whether done by research-institutions or by highly active practitioners, who cannot afford a test-phase with non-reliable performance. This contribution tries to supply some aspects of an engineering partner within a number of project-teams.

title Parametric Modelling of Architectural Surfaces
source Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 635-644
summary Parametric modelling is gaining in popularity as both a fabrication and design tool, but its application in the architectural design industry has not been widely explored. Parametric modelling has the ability to generate complex forms with intuitively reactive components, allowing designers to express and fabricate structures previously too laborious and geometrically complex to realise. This allows designers to address a project at both the macro and micro levels of resolution in the governing control surface and the individual repetitive component. This two level modelling control, of component and overall surface, can allow designers to explore new types of form generation subject to parametric constraints. Shading screens have been selected as the focus for this paper and are used as a medium to explore form generation within a given set of functional parameters. Screens can have many applications in a building but for the purpose of the following case studies, lighting quality and passive sun control are the main functional requirement. A set of screen components have been designed within certain shading parameters to create a generic component that can automatically adapt to any given climatic conditions. These will then be applied to surfaces of varying degrees of geometric complexity to be analysed in their ability to correctly tessellate and create a unified screening array true to the lighting requirements placed on the generic component.

source Open Systems: Proceedings of the 18th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2013) / Singapore 15-18 May 2013, pp. 685-694
summary The following paper explores practice based research as a means of identifying issues within current urban design methods. It considers the application of parametric systems as a means of addressing these issues. These systems are developed and tested across both Australian and international urban design projects within Grimshaw Architects. A methodology is proposed for the development and application of these parametric tools across multiple scales of design resolution. It reports on the application of a set of parametric urban scale massing tools in real world design projects. This exploration is carried out in distinct phases of design defined by the scale of resolution. The phasing allows for discrete problems to be addressed more effectively at different stages of the design process while still encouraging a seamless, bi directional workflow through a digital master model.

summary This paper addresses the current void between social agendas, environmental criteria and design methodology in urban planning through the implementation of new computational systems. It considers the application of digital design tools such as GIS and parametric systems towards more effi cient and effective design solutions. The digital design methods have been developed and tested within Grimshaw Architects Design Technology Group on both Australian and international urban development projects. A methodology for the use of parametric design for urban design development is suggested for defi ning, simplifying and categorising planning and design strategies. The following tools are a means of generating urban design concepts as digital forms in order to better inform the designer during the design process.

summary Architectural design is a very complicated process. It contains many sequences within the design process that the architects have to take into considerations. Within the process, the architect will look for every feasible schematic to make the best decision for developing the final design process. However, the preliminary design involves both conceptual and schematic design that concern about quantitative analysis and qualitative analysis. The objective of this research is to utilize an assistant method or tool to help form a preliminary design and a thinking process by using genetic algorithm to find the feasible solutions for conceptual and schematic design.

title Auditory collision warning signals for crane operation
source Automation in Construction 5 (6) (1997) pp. 445-457
summary This study examined the effect that an auditory collision warning signal's pulse rate, pulse pattern, and onset distance had on subject braking responses in a simulated crane/overhead power line collision scenario. The experimental warning signal alerted subjects of their proximity to overhead power lines. The experimental taks required subjects to monitor a simulated auditory collision warning signal while simultaneously operating a single-axis driving simulation task. The driving task simulated an actual crane operator's mental workload required to navigate a crane and manipulate various loads. Subjects were required to initiate braking responses based on the information conveyed solely through the auditory collision warning system. No visual information was provided to the subjects to isolate the effects of the warning signal. Subjective ratings of the auditory warning signals were obtained to compare subjects' actual performance using the warning signal versus their subjective preferences. Results indicate that subjects were able to initiate appropriate braking responses while using an auditory collision warning signal with moderate onset distances and low pulse rates. The auditory pulse pattern did not have a large impact on subjects' braking responses except at extremely short onset distances. Overall, it was concluded that a pulsing auditory warning signal comprised of a moderate onset distance and low pulse rate could work effectively as a proximity warning device for mobile cranes.

summary In order to provide a range of complex forms, justifiable to be selected in different aspects, the present work developed and evaluated a parametric and generative algorithm that allows to create diversified geometric options. The development of this work occurred in four stages, initially with the collection of information in the areas of architecture, parametric design and tools. Then the algorithm was developed with the aid of visual programming software. After, the geometric result was recreated in a physical model. Finally, we verified the potentialities of the use of the algorithm, and the use of a generative method.

summary The incorporation of virtual technologies to the learning process in architectural design is still incipient, using graphic software mainly as a rendering tool late in the curriculum. This paper presents an experience carried out with first year studio students, at the School of Architecture of the University of Chile, in which the intention is to incorporate virtual learning as part of the process spatial modification thinking. Through the use of Form Z, friendly software to learn for beginners, applied for simple extrusions, geometric transformations as translation, rotation or scaling, and the transformation of geometries and proportions through the handling of topological levels of polygonal objects. Through increasingly complex exercises we developed an effective complement of a traditional design methodology.

summary In the last decades, urban design has been influenced by its relationship with landscape. This has led to a new approach formalised and called Landscape Urbanism. Defining specific reading and analysis instruments together with proper design methods, capable of a transdisciplinary dialogue with geography, plant and biological world's languages, landscape urbanism can undoubtedly obtain more performing purposes than the ones achieved by traditional urban planning. Moreover, new digital tools are appearing, providing urbanism with new instruments for an advanced and interactive way to design cities in close relationship with landscape. The process starts with the acquisition of large quantity of data, like georeferenced maps in conjunction with relevant information about the territory, such as traffic and atmospheric pollution data, important buildings and monuments or significant landscape elements (rivers, mountains, etc.). All this information is combined onto multiple layers in order to be used by different design algorithms, connected by multi-dimensional arrays, whose reciprocal relations are dynamically controlled by architects and engineers. We will present here the case study of an ecological and regenerative infrastructure for the city of Bergamo designed on the basis of these principles, using a convenient combination of parametric tools.

summary Current research treats walkability in cities as an urban asset, to be identified by formal methods in order to let people benefit from it. In this paper, we take an activity-based view on the subject, arguing that walkability is not an end in itself but must always be seen from the standpoint of a specific activity to be performed. More precisely, we look at the specific walkability when seeking to perform an activity 'a' (e.g. shopping) within a given time budget 'b' (e.g. 15 minutes). Based on these two factors, we have devised a grid-based analysis method that computes transitions between grid cells. As result, we get a walkability map that extends the traditional 'proximity-based' understanding of neighborhoods by the notion of goal-directed pedestrians. To argue for the applicability of our approach, we showcase i it in two cities with different urban structure (Yerevan and Wiener Neustadt) before concluding.

summary The title comes from two different motives. At first it is a trial of excuse and introduces the subject of my exposure. The second reason is a way of improve dramatic accents from the beginning of my presentation. Computers are changing the world. Nobody can imagine a contemporary world without a useful help of them. We got used to the presence of computers in practically each area of existence. This presence is the first way in which computers are changing the world. The second way is less spectacular, but it completes the first one. It is an influence onto the human mentality and human way of thinking and working. This influence is often difficult to see and realize, but in my opinion is more interesting. Everybody knows that the computers are making the work of architects different. Is it a difference of quantity only or maybe also of quality? Which was the influence of computers onto an architectural space? Would it be different (better? worst?) if we were not used CAAD technology?

summary Education is an authority, it is a power. The power of independence and freedom first for teachers and then for theirs students. Teachers are responsible for an intellectual formation of students, who will build the future world. The teachers decide will they become creative people or only a well instructed members of a society. We are used to treat the education as a process of discovering and extending, but it can either be a process of covering and distributing only a selected part of knowledge. In my text I am trying to present a "picture" and a "word" as symbols of two kinds of transferring information, two kinds of culture, and education. The division line goes between teaching instructions ("pictures") and teaching ideas ("words").I am undertaking that subject because of the fact, that our life is more and more dominated by consumption, subordination to technology, and overproduction of senseless information. People are loosing theirs individuality. Our civilisation becomes very superficial and "pictorial". I belong to the "books generation", probably it is the last generation for whom the books are so important. I am conscious of that, and that is why I am trying to emphasise the importance of a "word" for a contemporary world, and for education.

summary The use of digital tools in the early, creative design process is the focus of an interdisciplinary teaching and research project. Starting from the question of how a seamless connection between physical and digital tools could be made possible, the proposed method tries to bridge the gap between both methodologies and provide intuitive, visual and collaborative design coupled with advanced, real time computer simulations. A design platform has been developed which supports a seamless connection between freely shaped physical models, GIS data and Grasshopper3D. The environment combines the reconstructed physical models with the digital one (surrounding buildings) and passes the information to a custom Grasshopper3D plug-in which serves as a link to existing and custom developed simulative tools. All simulations are performed and visualized in real time to support the intuitive and iterative design process.

summary This paper reports on a multi-disciplinary building design studio where a shared IFC (Industry Foundation Classes) building model was employed to support a collaborative design process in a studio-teaching environment. This project began with the premise that the efforts over the past decade of the International Alliance for Interoperability (IAI) to develop a genuinely operational building model schema has resulted in a mature technology that is now ready to be applied. This design studio experience sought to test that premise. The paper discusses the background to the idea of design collaboration based on a shared building model, placing this current work within that context. We look at both the nature of design decision-making, as well as the process opportunities afforded by close multi-disciplinary collaboration and rapid feedback from design analysis. Although the work was undertaken in a teaching context, the paper does not discuss the pedagogical issue, but rather concentrates on the operational issues that are encountered when working with a shared building model during a design process. The paper concludes with a statement of the lessons learnt and strategies to be adopted in future projects of this nature.

title An Urban Information Framework to support Planning, Decision-Making & Urban Design
source Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 653-668.
summary This paper reports on a 2-year research project undertaken in collaboration with a state planning authority, a major city municipal council and a government-owned development organisation. The project has involved the design of an urban information model framework with the aim of supporting more informed urban planning by addressing the intersection where an individual building interfaces with its urban context. This adopted approach enables new techniques that better model the city and its processes in a transparent and accessible manner. The primary driver for this project was the challenge provided by the essential incompatibility between legacy GIS (geographic information system) datasets and BIM (building information model) representations of the built form. When dealing with urban scale information, GIS technologies use an overlay mapping metaphor linked to traditional relational database technologies to identify features or regions in the urban landscape and attach attribute data to those in order to permit analysis and informed assessment of the urban form. On the other hand, BIM technologies adopt an object-oriented approach to model the full three-dimensional characteristics of built forms in a way that captures both the geometric and physical attributes of the parts that make up a building, as well as the relationships between those parts and the spaces defined by the building fabric. The latter provides a far richer semantic structure to the data, while the former provides robust tools for a wide range of urban analyses. Both approaches are widely recognised as serving well the needs of their respective domains, but there is a widespread belief that we need to reconcile the two disparate approaches to modelling the real world. This project has sought to address that disjunction between modelling approaches. The UrbanIT project concentrated on two aspects of this issue: the development of a framework for managing information at the precinct and building level through the adoption of an object-oriented database technology that provides a platform for information management; and an exploration of ontology tools and how they can be adopted to facilitate semantic information queries across diverse data sources based on a common urban ontology. This paper is focussed on the first of those two agendas, examining the context of the work, the challenges addressed by the framework and the structure of our solution. A prototype implementation of the framework is illustrated through an urban precinct currently undergoing renewal and redevelopment, finishing with a discussion of future work that comes out of this project. Our approach to the implementation of the urban information model has been to propose extensions to ISO/PAS 16739, the international standard for modelling building information that is commonly known as IFC (Industry Foundation Classes). Our reason for adopting that approach is primarily our deep commitment to the adoption of open standards to facilitate the exchange of information across the built environment professions, but also because IFC is based on a robust object schema that can be used to construct a internet-accessible database able, theoretically, to handle the vast quantity of data needed to model urban-scale information. The database solution comes with well-established protocols for handling data security, integrity, versioning and transaction processing or querying. A central issue addressed through this work is concerned with level of detail. An urban information model permits a very precise and detailed representation of an urban precinct, while many planning analyses rely on simplified object representations. We will show that a key benefit of our approach is the ability to simultaneously maintain multiple representations of objects, making use of the concept of model view definitions to manage diverse analysis needs.

summary We report on a method that has been tested to produce the working drawings for site communication of the architectural project. The advantage of using such a method is that it allows improving the architect’s control over design while maintaining the traditional role of drawings; at the end, it will be possible the delivering of a flexible set of information more suitable to the building needs. This work is part of larger efforts to investigate the conventional methods that architects use to communicate their ideas to the builder and the potential of information technologies for partially automating this process. The research described in this paper was developed at LNEC. Funds were granted by FCT, under a Portuguese program for promoting scientific research within architecture and urbanism (PRAXIS XXI/2/2.1).

title Global Visualisation Engines – Issues for Urban Landscape Planning Participation Processes
source Digital Design in Landscape Architecture 2008, Proceedings at Anhalt University of Applied Sciences, 29-31 May 2008
summary Traditional planning processes use two-dimensional drawings, plans, sections, elevations and artists’ impressions to communicate design intent to interested parties. Three-dimensional computer visualisation technologies that support the planning process raise institutional and organisational challenges as their perceived benefits are considered. Virtual Reality (VR) models add interactivity and immersiveness to landscape visualisations but require appropriate technical input and management. This paper explores two main themes. Firstly, how interactive 3D computer simulations of planning proposals can be adopted to successfully improve the traditional process. It reports on a pilot study to examine how architects, clients, planning officers and university researchers have worked together to systematically examine and analyse this changing process. It reports on issues concerned with ownership of city models, the roles and the compatibility, accuracy and remote sharing of urban data. Secondly, we explore the emerging theme of web-based GIS applications and their impact on architectural visualisation. The process of placing urban data onto Google Earth was tested and the resulting issues emerging with this software, including IT and data management and accuracy issues for suitable architectural visualisation are discussed. The study also reports and offers an overview of placing accurate urban landscape data onto Google Earth and a discussion of using this method for online public participation and communicating technical building information.

summary Digital media and interactive technologies provide the opportunity to augment and alter the characteristic qualities of sensual and aesthetic perception. The visual and auditory senses are culturally predominant, but nevertheless the sense of touch receives nowadays increasing attention. This paper presents the perceptive potentials of touch sensations and their influences on our emotions. We will discuss how we can take advantage of these potentials using digital media and technology and how touch stimuli are forming aesthetic experiences. In this paper we are investigating the influence of an interactive "skin" - prototype on the human touch perception in the architectonical context.

A variety of software and algorithmic methods enhance our possibilities in advanced building design. Yet our build environment is perceived with our body and senses. In this paper I present an information visualization course, which gives students an analysis method to interlace and understand the complex relationship between physical phenomena and qualitative evaluation of space. The tools and methods to achieve this aim were a combination of sensor technologies, algorithmic data visualization and phenomenological inquiry.

title Sensitive Voxel - A reactive tangible surface

summary Haptic and tactile sensations, the active or passive exploration of our built surroundings through our sense of touch, give us a direct feeling and detailed information of space, a sense of architecture (Pallasmaa 2005). This paper presents the prototype of a reactive surface system, which focuses its output on the sense of touch. It explains how touch sensations influence the perception of architecture and discusses potential applications that might arise from such systems in the future. A growing number of projects demonstrate the strong impact of interaction design on the human senses and perception. They offer new ways of sensing and experiencing architectural space. But the majority of these interaction concepts focus on visual and auditory output-effects. The sense of touch is typically used as an input generator, but neglected as as a potential receiver of stimuli. With all the possibilities of sensors and micro-devices available nowadays, there is no longer a technical reason for this. It is possible to explore a much wider range of sense responding projects, to broaden the horizon of sensitive interaction concepts (Bullivant 2006). What if the surfaces of our surroundings can actively change the way it feels to touch them? What if things like walls and furniture get the ability to interactively respond to our touch? What new dimensions of communication and esthetic experience will open up when we conceive of tangibility in this bi-directional way? This paper presents a prototype system aimed at exploring these very questions. The prototype consists of a grid of tangible embedded cells, each one combining three kinds of actuators to produce divergent touch stimuli. All cells can be individually controlled from an interactive computer program. By providing a layering of different combinations and impulse intensities, the grid structure enables altering patterns of actuation. Thus it can be employed to explore a sort of individual touch aesthetic, for which - in order to differentiate it from established types of aesthetic experiences - we have created the term 'Euhaptics' (from the Greek ευ = good and άπτω = touch, finger). The possibility to mix a wide range of actuators leads to blending options of touch stimuli. The sense of touch has an expanded perception- spectrum, which can be exploited by this technically embedded superposition. The juxtaposed arrangement of identical multilayered cell-units offers blending and pattern effects of different touch-stimuli. It reveals an augmented form of interaction with surfaces and interactive material structures. The combination of impulses does not need to be fixed a priori; it can be adjusted during the process of use. Thus the sensation of touch can be made personally unique in its qualities. The application on architectural shapes and surfaces allows the user to feel the sensations in a holistic manner – potentially on the entire body. Hence the various dimensions of touch phenomena on the skin can be explored through empirical investigations by the prototype construction. The prototype system presented in the paper is limited in size and resolution, but its functionality suggests various directions of further development. In architectural applications, this new form of overlay may lead to create augmented environments that let inhabitants experience multimodal touch sensations. By interactively controlling the sensual patterns, such environments could get a unique “touch” for every person that inhabit them. But there may be further applications that go beyond the interactive configuration of comfort, possibly opening up new forms of communication for handicapped people or applications in medical and therapeutic fields (Grunwald 2001). The well-known influence of touch- sensations on human psychological processes and moreover their bodily implications suggest that there is a wide scope of beneficial utilisations yet to be investigated.

title Adaptive Pneumatic Shell Structures - Feedback-driven robotic stiffening of inflated extensible membranes and further rigidification for architectural applications

summary The paper presents the development of a design framework that aims to reduce the complexity of designing and fabricating free-form inflatables structures, which often results in the generation of very complex geometries. In previous research the form-finding potential of actuated and constrained inflatable membranes has already been investigated however without a focus on fabrication (Otto 1979). Consequently, in established design-to-fabrication approaches, complex geometry is typically post-rationalized into smaller parts and are finally fabricated through methods, which need to take into account cutting pattern strategies and material constraints. The design framework developed and presented in this paper aims to transform a complex design process (that always requires further post-rationalization) into a more integrated one that simultaneously unfolds in a physical and digital environment - hence the term cyber-physical (Menges 2015). At a full scale, a flexible material (extensible membrane, e.g. latex) is actuated through inflation and modulated through additive stiffening processes, before being completely rigidified with glass fibers and working as a thin-shell under compression.

summary Typical horizontal building types, open spaces, and human activities have yet to competently overcome or adapt to the constraints of vertically-oriented dense urban environments. Designing the built environment to the oblique, or more than two axes at once, is a required strategy for the future of city planning, the advancement of body-space interaction in architecture, and to reinforce the interconnectedness of the natural environment with human activities. With the development and increasing use of 3D modeling software, parametric and generative design processes, and the progressive investigation of complex geometry, it is likely that the oblique will be envisioned more and more as a functional architectural device. This research investigates the tessellation of minimal surface geometry to achieve a folded, multi-use surface capable of connecting disparate urban program and which can enable a city to offer amenities that are typically available in horizontally-oriented suburbs. The geometric family of the helicoid is found as the optimal formal generator because of its ability to create a continuous surface while allowing for both horizontal and vertical circulation.

summary This work presents the synthesis of a model of urban growth dedicated to accomplish simulations of urban spatial dynamics, based on integrated urban and environmental factors and promoting simultaneity among external and internal growth. The city and surrounding environment are captured and modeled in computational ambient, by application of the centrality / potential model (Krafta, 1994 and 1999), with support of graph theory, cellular automata, GIS and geocomputation. The model assumes the city as a field of opportunities for obtaining income, mediated by the space, which is composed of urban and environmental attributes, that work as attractors or as resistances for the urban growth. The space configuration and the distribution of those attributes generate tensions that differentiate qualitatively and quantitatively the space, through the centrality measure (built with the support of graphs techniques), coming to provoke growth in places with larger potential of development (built with the help of techniques of CA – cellular automata). Growths above environmental thresholds are considered problems, generated and overcome in the same process of production of the urban space. Iterations of that process offer a dynamic behaviour to the model, allowing to observe the growth process along the time. The model presents several possibilities: a) urban - natural environment integration; b) internal and external growth integration; c) variety in the scale; d) GIS integration and geocomputation; e) user interface; f) calibration; g) theoretical possibilities; and h) practical possibilities.

title Built Form Impact Assessment Method of Description
source Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings (Spa, Belgium), August 18-21, 1996
summary Continuous change in contemporary cities heve produced an urban space tipollogically diverse, particulary in fast growing South-American countries. As a result, the straight contextual analysis, usually used to assess the degree of innovation/permanence of new buildings in urban settings becomes ineffective, for the simple reason that frequently it is virtually impossible to establish what the context dominance actually is. The method proposed in this paper takes the issue of tipological analysis from a systems approach. This is carried out by a series of procedures, such as: a) identifying buildings'constitutive parts, which can be done at any degree of detail; b) listing them according to their attributes of repertory and formal composition. ;with this it is obtained a extensive catalogue of the entities taking part of the considered urban setting, from which the actual context can be depicted; c) listing each entity's participation in the landscape composition, or the role each one has in the landscape configuration. The software that operates the analysis does the rest, measuring the degree of innovation/permanence of each entity, in relation to the others, and defining what the context is made of.. From this, any inclusion/exclusion in the considered townscape is automatically evaluated in terms of impact on the pre-existing setting. The system can be used at any urban scale, as well as at the building scale.

source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary After the wide-spread use of computers as task processors, either for algorithmic operations, or for advanced interfaces, the emphasis has shifted on computers as communicators. Beyond basic serial communications, computers serve as providers of information, linking organizations and expanding the bounded rational of professionals. Based on the use of computers as communica-tors, a multiplicity of visual databases for architecture have emerged in the recent years. Building on a maturing technology, those databases address different domains of design, either aiming to provide the designers with information for making informed decisions, or aiming to document prior designs. However, a common characteristic of those visual databases is a separation between the design of the database, versus the entering of the critical amount of data that can make the databases useful. While the research has progressed in the designs, and technological problems of data presentation and data transfer have reached workable solutions, most of the efforts have not succeeded yet in providing the critical mass of information that is required to make the use of the databases desirable. Furthermore, this effort seems as having less research interest, while the necessary amounts of data, and especially the updating of those data, makes the task impossible for academic institutions, and requires interorganizational efforts. This paper focuses on the duality of the databases, either as a form of documentation, or as on-line interactive information systems. Based on that distinction, it examines the required technology and the critical success factors of each type, and proposes that these databases add value to design and they have considerable market effects, which will drive their development and diffusion.

summary The present study tries to investigate the Brazilian hackers´ artistic and communicational manifestations. We tried to understand how they use the digital technology for expression of their identities and transmission of messages in defaced homepages. The integration of different chains of thinking made it possible to build a schematic diagram and the establishment of conceptual categories for a graphic analysis and for the analysis of the messages present in the defacements by the Brazilian hackers. From these analyses we could see that the Brazilian hackers express their identities through their nicknames and defaced pages. These pages have a common underlying structure marked by the linearity, the identification of the one(s) responsible for the defacement, the message left for the administrator of the defaced page, the personal statements and the exhibition of the elements for contact with the defacer(s).

summary Differently from other regions in the Planet, since 2010, in Latin America textual programming language (Rhinoscripting) is being replaced by its visual equivalent (Grasshopper). This is a consequence of our preference for an interactive platform, and because our design problems are not as complex, so we aim to control geometrical problems or aspects belonging to an product scale instead of an architectural one. Problems emerging when creating code could be improved by modifying and reusing existing solutions as a starting point, since learning would not be centered in the object but in the process of creating it, using a suitable instrument.

A 'generic' object-oriented approach to product modelling allows multiple design representations to be described as different views of a common, gradually evolving building product model. The product model provides the capability to generate, in successive design iterations, a coherent description of the form, structure and dimensions of the building and its assemblies and components.

summary A great part of our physical environment and existence is currently undergoing an epochal transformation from a solid to a liquid state on many layers of technological evolution. Optical phenomena and radical shifts in visuality, particularly manifest through media propagation are impacting on urban space in unpredictable ways. City - space is not only perceived as a physical place but also simultaneously inhabited as a virtual site. Both conditions form the hybrid of an urban realm, construed as surveillance, simulation, distraction and a relentless proliferation of information. Ultimately, all man-machine interfaces of hardware will be adequately infinitely machined. This process however will continue beyond the now experienced level of TV, video, cellular-phones and computers, incorporating interconnected surfaces of text, music and other kind of data. The surrounding sensorium will penetrate the phenomenological tissue of our nervous system to the extent that we are unconsciously fluidly interacting. Behavioral properties of matter and their smooth transmittal of visual, sound and tactile sensations, will provide an intellectual and sensual presence which renders space and its perception as being liquefied. Also the interrelation between the exterior and interior usage will be smooth and multidimensional, as the building’s envelopes are capable to alter their properties in response to contextual changes or movements. A redefinition of the disciplines of architecture and urban planning responds to the changes in cultural, social, political and economical milieus.

summary A person is a wonderful creature. His high organization helps him not only to see and to hear the world around him, but to feel and understand, to condole and pity. A person is a sacramental creature too. His complex organization helps him to see day as light and darkness, as delivery and death, as delight and grief. Every human reaction has biological, physiological and sensitive components. That is why environment is able to call up physical an emotional associations. A human being can "see" sound and "hear" colours. All history of human culture shows that the art can affect man in different ways: unconscious effects, spontaneous associations, general symbolic or specific conventional meanings. That is why architecture can not only protect (a safeguarded aspect), but give knowledge ( an informational aspect) and set up mood (an emotional aspect). And that is why we speak about ambiguity of sense and about multiartistic works. Such as Skriabin's symphony 'Prometheus'. Two scores - musical and colouristic - are connected in this masterpiece. Let us look through two architectural disciplines—from this point of view. The programmes of these disciplines are examples of such embedment. Any architectural discipline demands computer graphics. Any architectural discipline demands multimedia aided teaching, because multimedia in computer designing is a result of human being's complexity and ambivalence.

summary There is an absolute dependence between the professional colour culture and the sphere of professional architectural tasks. From the skill to know how to handle brush up to the skill to convey one's own conception to the customer. Colour sketch, polychrom model, means of computer aided design, colour schemes and diagrams, are the means, which modern architect must wield. Actually an architect must think "by colours" from the very beginning of designing and must use colour as a compositional expedient. Architectural colour theory gives the students of the architectural department fundamental rules of colour science and methods of their practical utilization. But today the real designing demands the wider utilization computer of the graphic. There are a lot of remarkable graphic packages, which help architects to wield vector-mode graphic display and roster- mode graphic display, to work with colour and shape. That is why it is necessary to teach students to use the possibility of computer designing in the field of architectural colour science. This task determines the general matter and direction of teaching programme, defines the character and the way of its composition, The teaching programme is adapted for using the graphic package "Corel DRAW-5.0". Students work with a simple set of software tools "Corel DRAW" and at the same time acquire habit of working with the graphic package and decide problems of plane and volume colour simulation. The main practical tasks - colour on perception, psychological influence of colour people, colour harmonies, are performed by the way of "colour modelator". With the help of uncomplicated transformations it helps to receive a necessary set of simple figures for colour exercises.

summary Urbanisation carries in substantial variations in human life, such as the bad air, dirty water, heightened radiation which are the main reason of the hygienic discomfort. But this is not only ecological problem, there is one more - the visual discomfort. Human being is forced to live in the environment of huge flat areas with straight lines, right angles, and uniform painting. The visual comfort is related to natural world of trees, mountains, includes acute angles, crooked lines, colour diversity. That is an environment with a great variety of natural visual elements. Ecological expediency is obtained when colour environment possess the informational sufficiency and provides emotional and visual comfort.

title Designing the Undesigned: Emergence as a tool for design
source International Conference on Generative Art
summary Design, as an act and a result, is a natural part of the larger biological context in which we live. It is both a behavior and a tangible side effect of the organic system from which it arises. A design can be characterized as a physical exemplar of the concept of memes, the 'genetic' building blocks of ideas or units of cultural transmission. In this capacity, design has served to extend humankind's reach and ensure and enrich humankind's survival in the full range and variability of conditions the Earth has to offer. In a very real sense, design has 'evolved' its own rich ecosystem, with a robust diversity of elements, dynamics, and interrelationships rivaling that of the organic system from which it derives. In the ecology of design, designs obey laws analogous to the laws of survival and selection that organisms in nature obey. Given the recent advances in understanding and modeling of the biological and physical systems, it is not surprising that artists and designers are now turning to these models as a 'new' resource for the conceptualization and design of structured artifacts and spaces. While there are many fundamental technical issues surrounding development and application of generative models and processes, the relationship of artist to the process of creation is a central issue in the scaling up and widespread accessibility/acceptance of the generative approach. This paper will present a set of observations from the perspective of a small company of artist/ technologists trying to bridge the commercial and artistic application of generative processes. Specifically, the paper will explore some approaches to the designer/system relationship and process control metaphor, the balancing of serendipity and design convergence, the definitions and representations of design spaces, and finally, present some ideas about the future prospects and promising new techniques for generative design.

summary Propose: Costs are a major issue in low-cost housing projects. Traditional project process uses estimated cost studies and comparative methods in initial phases, but the cost itself is elaborated only at the end phases, generating significant re-working and changes in specifications and drawings. Is desirable to use tools that possibility more integration between costs and architectural projects. Some CAD software already offers these tools, but they are not use by architects. This work intention is search in these tools the integration between costs and architectural projects. Methods: To use software Vectorworks in a low-cost housing project, Residential Serra Verde; incorporate cost aspects at initial phase by parameterization of 3D model; analysis of cost and project results. Findings: validation of cost estimative with the utilization of tested procedures. Value: developing a simple methodology of cost estimation and integration with architectural project.

summary A design process is traditionally viewed as a sequential process model from the formulation of the problem to the synthesis of solutions. Simon (1981) regards design as a state-space search where a problem leads to the solution. To be more practical, there are many versions of solution generated during design, where each current one is an improvement over the previous one. This kind of synthesis of solutions can be viewed as an evolutionary system over time. We propose to apply the metaphor of "exploration” to design, and further argue that evolution occurs in the problem space as well as in the solution space. Co-evolutionary design is introduced to remove the assumption of having a fixed goal (problem). The problem is allowed to change over time. Two algorithms for co-evolution are presented. Their characteristics and differences are highlighted. The paper moves on to review the design history of the Sydney Opera House and to show how observations from this real life example confirm our co-evolutionary model.

title Ratios for cost control
source Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary The design of buildings takes place in phases representing a development from rough to precision planning. Estimates are made in order to test whether the result is still within the budget set by the client or developer. In this way, the decisions taken during the design phase can be quantified and expressed in monetary terms. To prevent blaming the wrong person when an overrun is discovered, the cost control process has to be improved. For that purpose, two new procedures have been developed: (i) a new translation activity; and (ii) ratios by which quantities can be characterized. 'Translation is the opposite of estimation. A monetary budget is converted -'translated' - into quantities, reflecting the desired quality of the building materials. The financial constraints of the client are thus converted into quantities - the building components used by the designers. Characteristic quantity figures play an important role in this activity. In working out an estimate, the form factor (i.e., the ratio between two characteristic values of a building component) has to be determined. The unit cost is then tested against that ratio. The introduction of the 'translation' activity and the use of characteristic quantity figures and form factors enhance existing estimation methods. By implementing these procedures, cost control becomes considerably more reliable.

summary We present a tool which empowers 'green' design freedom for architects by presenting ever expanding choices in components and materials and automatizing their configuration and placement. Several time- and resource- consuming initial design iterations are eliminated by optimizing the energetic efficiency of the building in the original draft phase. The smart, efficient, energy producing building of the future can thereby offer increased cost and energy efficiency, security and comfort, without any compromise in style and form - on the contrary, the proposed tool stands to open up a novel palette of creative 'green' architectural design elements, which would effectively be co-designed by architects. The proposed algorithmic CAD design tool allows direct integration of renewable sources in the architectural design phase, taking into account local meteorological and solar radiation conditions. Furthermore locally optimized evolution and modification of renewable components integrated into the building's structure is possible, leveraging an increasingly wide range of possibilities in form, finish and renewable energy generation.

summary This paper reports on some recent research carried out to develop computational generative urban design system that can be used as an alternative approach to master planning. The focus of the investigation is an 11 ha site located in the South-East edge of Auckland, New Zealand. The urban (or sub-urban) morphology is modelled as cellular automaton based on Hillier’s (1984) x-y syntax in order to resemble the morphology of the existing village. An agent based system based on Reynolds’ (1987) flocking algorithm evolves synchronously with the automaton and tests its ecological fitness. The emergent pattern of development therefore results from the mutual co-adaption of the cellular automaton and the agent based model. The outcomes are variety of spatial morphologies that connects well with adjacent existing village and at the same time take into account landscape and ecological peculiarities of the site.

title Towards an Object-Oriented Language for the Declarative Design of Scenes

summary We propose a prototype “kernel” of an object-oriented language, SOML (Scene Objects Modeling Language), intended to assist in the declarative design of scenes in image synthesis. This language is an attempt to provide the designer with a tool to facilitate the rapid prototyping of 3D scenes. It can also serve as a tool for knowledge acquisition and representation , and for communication and exchange of data with other tools in a design environment. Advantages offered by the implementation of SOML are: (a) from user’s viewpoint: the possibility of declarative description of the initial concept associated with the target scene in terms of properties and constraint vocabulary, the possibility of quantitative and qualitative reasoning on these properties, the modification of the intermediate solutions to different levels of detail, the utilisation of previous solutions; and (b) from the implementation viewpoint: the structuring of the properties and methods in the form of domain knowledge, the optimal solution generation according to heuristic causal-probabilistic criteria, the transformation of the semantic concept description of the scene in generic entry code for a geometrical CSG modeler or for rendering and visualization software, the integration of functionality for parameter generation and modification, the compilation of a scene from components of other final scenes and operations of geometrical transformations acting on groups of scenes. We present the architecture of the object-based implantation of the language and its interpreter, in the unified notation formalism UML. The utilization of the SOML language is illustrated by some examples.

source Architectural Information Management [19th eCAADe Conference Proceedings / ISBN 0-9523687-8-1] Helsinki (Finland) 29-31 August 2001, pp. 92-97
summary This paper discusses methods for information management through the rational application of IT within collaborative design. We explore the possible integration of the platforms of case-based reasoning and information structures. We examine the potential combination of existing techniques (CAD-tools, word processors, general applications, WWW) and standards (IFC, national classification systems) into a system for information management. We focus on the designers’ use of heterogeneous information and the further development of a prototype based on product-model and process-model technology. Today, XML helps us structure various kinds of information before the system performs case-based reasoning sessions. The aim is to promote efficient and flexible information management in a casebased design process. Through the use of standardized product models, this information will be sharable and suitable for reuse and feedback. The more often the information is reused, the more general and adaptable it becomes i.e. it evolves. This scenario requires, though, efficient information management in the design office: a quality system for evaluating the information for reuse, consequent use of standardized product models and IT.

title Model of Design Parts and its Use to the Design Team
source CAADRIA ‘98 [Proceedings of The Third Conference on Computer Aided Architectural Design Research in Asia / ISBN 4-907662-009] Osaka (Japan) 22-24 April 1998, pp. 233-242
summary This paper discusses the impact of the choice of representation on the final result in design and construction projects. Representation is an integrated part of the design process used by architects as a communication tool to help them present a concept to their clients and other consultants. The representation choice, in addition, reflects the professional’s perception of the design process and the architectural artefact. Architects’ offices work with a wide range of problems - aesthetic and spatial issues, detailing, choice of materials, and systems design. The multiplicity of representations enriches the understanding of these issues. Today, the model-oriented approach in design is common among both architects and leading software producers for the construction industry. While STEP (Standard for the Exchange of Product Data) aims at developing very comprehensive product models, we examine the possibility of building up a small-scale model responding to the information needs of a design team. In our research work, we view a model of design parts as a suitable carrier of information allowing the designers to store data reflecting their accumulated and refined professional knowledge and experience. Besides, the team of architects can later easily retrieve information needed for future design reuse from the model. To reuse design solutions and learn from previous work is an essential part of the professional culture. The construction industry as a whole has been slow in implementing information technology to improve the work methods. Neither have architects’ offices used the full potential of this technology to structure information and rationalize the design process. The objective of this study is to examine whether information technology makes it possible to organize all the design information in an office archive. The proposed model of design parts relates to national standards and universal models for product data representation and exchange, such as STEP. Today, the construction sector is becoming increasingly aware of the potential of the model-oriented approach both to rationalize the design and construction process and offer designers new options to store, broaden and reuse professional knowledge. We have used the information modelling language EXPRESS to describe our concept.

Mais il semble que la société moderne ait déjà omis pour toujours la première voie : au réseau télépathique, nous avons privilégié le réseau télématique. Il est difficile d'évaluer les conséquences sociales et psychologiques d'un tel choix. Néanmoins, la prudence nous oblige à garder notre autonomie de la technologie. Alors, il faut la maîtriser au fond, et surtout former la génération future de façon non seulement pratique mais aussi philosophique et critique par rapport à elle. Seule l'imagination peut surpasser les prouesses technologiques. Comme le dit Umberto Ecco «même à défaut de génie, l?imagination est toujours créatrice .

summary Do Information Technologies (IT) as a medium create and reinforce the "computerised craftsmanship" side of architectural design education to the detriment of "learned designer" side? Or do they allow these two opposite approaches to come nearer, to merge, and give rise to a new pedagogical experiment? The answer could be drawn from the various experiences and practices employed in practical teaching.

source CAAD futures ‘87 [Conference Proceedings / ISBN 0-444-42916-6] Eindhoven (The Netherlands), 20-22 May 1987, pp. 209-216
summary How we see things depends on our education and our cultural pre-suppositions. This does not allow to convey some logical form, but nevertheless makes possible a more global and less formalized understanding of the objects, their environment and their physical proprieties. In architecture, the digital image acts according to two directions: (-) representation: the fine images are a means of communication between the different parties implementing building projects. (-) modelization: in addition to its iconic qualities the layers of different models simulate the most different aspects of the ,image and the environment characteristics. // At this level our vision is directly concerned with the design of the studied object; it acts both in the design process and in the expression of our conceptual images. How does modelization work? Infographical representation deals with a more or less schematic and conceptualized world the reading of which is more typified than particularized. It deals with a schematization nearly "ideographical" of the mental image thus is produced "synthetism", a neologism similar to such expressions as realism or abstractionism.

title "To See Ideas" or The Visualizing of Programmatic Data Reading Examples in Architecture and Town Planning
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary Whether images are still in the mind, metaphors, sketches or icons, they play a crucial role. They have always been the heuristic pivot around which the process of artefact design organizes itself, particularly in architecture and town-planning. "To see ideas" through computer ideograms is to experiment an interesting and new direction for "pictural approach" supported design. Cognitive psychology emphasizes the important part played by mental images in reasoning, imagination in the working of human intelligence and the construction of mental images as cognitive factors underlying reasoning. It also points out how close computerized objects and mental schemata are. "To reason over a situation is first to remember or build some mental models of this situation; second to make those models work or simulate them in order to observe what would happen in different circumstances and then verify whether they fit the experiment data; third to select the best model, a tool meant to sustain and amplify the elaboration of mental models, which is a spontaneous activity". We introduce our exploration of the direct transmission of mental models through computer ideograms. We study the "operative" and the "expressive" aspects, and this allows us to analyze how some aspects in a field of knowledge are represented by ideograms, schemata, icons, etc. Aid to imagination, reasoning and communication by means of a graphic language must be limited to some figurative relevant aspects of the domain considered; it should not aim at a realistic simulation. Therefore, the important role played by icons and the spatial schematic representation of knowledge is emphasized. Our hypothesis is that an architectural concept does not result from an inductive process, but rather is built to solve problems through the direct representation of ideas with ideograms. An experiment was conducted with a graphic language, a dynamic scenography and actor-objects. The language allows one to build and visualize models from the various domains of knowledge of the object. The dynamic scenography can explore and simulate kinetically those models by means of staging various narrations and visual scenarios. The actor-objects play various and complementary parts in order to make the image explicit and link it with the concept. We distinguish between two parallel levels of reality in computer ideographics: one concerns the model, it represents the visualization of a graphic model at a particular moment and according to a particular representation, the other concerns the ideogram.

summary Reflection about the architectural programme starts with the analysis of its writing, its "style" which bears not only the "griffe" of the programmer but as well the structure, methodology, codes of reading, etc. particular to a programming approach. The programme structure corresponds in most cases to the different levels in the text's format and the composition modes of representing data and their relations. The choice made can either facilitate or impede the reading as interpretation of the programme. The programmer’s aim should be to open the text to reading towards a "synthetic schematic" summary, a sort of cognitive threshold which allows the reader to understand both the client's objectives and the designer's intentions enhanced by his experience. Articulating a designer's experience means focusing on his knowhow and memory. The designer's recollected knowledge and heuristic approaches to the solution of a basic design problem - types, his readings and spatial evaluations permanently feed the knowhow. It is important for the architect to have access to past examples, to the collective memory of his workplace, and a repertoire of readings, notes, sketches, influences and citations. It is therfore equally important that a computer environment also have a multimodal "architect's memory" or "project memory" module in which different forms of representation are classified, and made accessible as memory components. It is also necessary to have the possibility to access at any moment in an interactive manner to the recomposition, addition and adaptation of these mnemonic components. The information coming from the programme, classified as descriptive, prescriptive and quantitative types of data, must be able to be interrogated in different modes of representation : text, matrices, nets, diagrams, and so on, so that the pertinent information can be extraded at any given design process stage. Analysis of competition programmes show that often the description of an activity, for example, the Great Stadium competition in Paris, is described by several pages of text, a circulation diagram with arrows and legend, a topological proximity diagram with legend and as table activity - areas . These different representations, which are supposed to be complementary and give the most pertinent view of the client needs, show in fact after analysis, many description problems, incoherance, and which result in a reading difficulty.

summary Our fashion of thought is dialogic in its way to use simultaneously logic- mathematics and analogical approaches (Morin, 1986). The analogy works as well at the level of the unconscious by the construction of an analogon that permits us to recognise a face between thousand of others, despite changes intervened in time; as consciously where by an effort of constructive analogy, we establish bridges between different events or domains giving to the design a new lighting that puts it on the way to a solution. For this reason visual approach acquires a great importance in the establishment of similitude in conception. Many testimonies of scientists, philosophers, artists confirm this observation about their creative work, while underlining the danger of no founded analogies. In current life, analogy brings a support of likeness to the daily conversations, and the possibility to advance in the dialogue by a chaining of analogies having for objective to strengthen the speech.

summary Calculations are used to forecast urban flows of population, development of various activities, demography, and many other architectural programme constrains, and have been spontaneously the first field of computer intervention in urban and architectural project design. By analogy to engineering where computation is the base of decision making, architectural design process is seen as a problem solving process. <> constrains computer aided computation is seen as Computer Aided Architectural Design, CAAD. This way, a technological utopia called CAD in architecture is born. Nevertheless, the review of architectural design methods has clearly shown that programmatic models, since they are only used to evaluate spatial hypothesis, and do not have in themselves space production potentialities. In spite of the powerful methodological movement of the sixties, that have established this design constellation, the misunderstanding persists until now. Architect is a gestural and visual being. By using simultaneously metaphor, gesture and calculation, he calls for all his experiences and sensibility to realise plastic and poetic synthesis of form. To remedy to the major problem of the form synthesis, graphical instruments have been proposed. Why not utilise tools used in the field of engineering as computer aided drafting ? And so, computer aided drafting triumphaly entered the architectural design process. But, computer aided drafting is commonly seen as an instrument used on the - projection - stage, where drawings are produced for an already designed object. A new myth that assimilate architectural design to the drawing production activity arrives with the <>, containing thousands of drawings. All this aimed to facilitate, as it is proclaimed, communication between all the intervening in the project.

summary The increasing instrumentation of the design process can transform it into a site of virtual: architectural, structural, psychological, sociological, …, experimentation. Thanks to that, architecture that was never thought as a scientific discipline seems at last to enjoy a virtual laboratory of pure research. This visionary space of experimentation of potential architecture must assure the return of performances obtained in the constructed environment. But, to make such a future certain, one has to start with pedagogy, where the laboratory of potential architecture must constitute a real construction site of the imaginary.

summary The projectual disciplines must respond with some grade of originality to a approached problem. In order to products of design be creative must be implemented a creative process of design and also from the teaching. The essence of creativity are the variations over a subject. A pedagogic way for this, is the one to recognise, individualise and represent the problem attributes, building upon them an "exploration space", to analyse and create new combinatorial alternatives or restructuring of the problem. The digital media incorporation as a new proyectual environment approaches the interactivity not only of the combinatorial variables, but, also to the hypermedia's. Both the digital documents, as the creative process, have a "no linear" or a "net" structure, that allows the construction of a himself way, self-managemented into this structure. The interactivity makes possible to work, as the divergent thought does, in a "polydirectional" field, that stimulates the fluency, the flexibility and the originality. The new- media's, used as didactic tool, open to "action", allow the students to convert them in "co- author", together professors, about themself learning process. >From this educational conception and its potential enrichment with the hypermedia, we are designing a project of digitising of an exercise to our didactic proposal and its later application into the course with our students.

summary The textile surface presupposes infinite limits and contained in each one of its minimum parts the total information of the complete system, the singular sign that repeats itself with infinite criterion in a limited field. The textil proposes, simultaneously, the limit and the excess. The logic of the constructions by repetitions is based in the coordinated interaction of the part and the whole. IT CONSTITUTES A SYSTEM, with variations from simplicity to complexity, in the estructural morphology and in the surface. The recuperation of a totality/ continuity concept in a teaching- learning strategy, implicates the manage in all senses of a multidirectionel space, today indispensable, in the convivences of the analogic and the digital. Immersed into a culture that repeats the fragments on a seduction of the representation to the representation itself, the generation of a place of flexibility and interaction is the instance to the knowledge construction.

summary This paper reports on the findings of an empirical investigation into the impact of different media on design methodology. The statistical sample included 49 fourth year architecture students, divided into three groups: the drawing group, the physical model group and the computer group. They were given a problem of designing a façade in an urban context in Glasgow over a two week period. The design process of each group was monitored over that period through observations, recordings and attitude measurement via a questionnaire survey. The results were analysed using the Statistical Programme for Social Sciences (SPSS). The dendrograms from cluster analysis revealed that there were well established perceptual dimensions, or clusters, for the façade’s design variables within the three groups because of using different media. The impact of media on design creativity, both as a process and a product, was investigated. All three media types yielded a positive correlation between ‘media made design decisions more creative’ and ‘media made design scheme more creative’- with a correlation coefficient of 0.708 which was significant at the 0.01 level, p<0.05.

Users can extend virtually unlimited capabilities. For this reason we have chosen a BIM with programmability by the user to create a calculation module to validate, the heat transfer and possible condensation on both walls and ceilings. The Revit Architecture BIM was chosen using the API (application programming interface) in C#. In this paper, we analyze the experience gained and the results achieved. The objective is to create a calculation and graphing module thermal transmission and condensation.

summary This article relates a teaching experience in the discipline “InfoAU II” at the CAU/UFPE/Brasil. One of the objectives is, working with the students, reflecting about the design as a multidisciplinary knowledge integration process. The other one is opening a discussion about the importance in the Information management in the process of design teaching in Architecture, Urbanism and Landscaping within digital environments. The methodology involves a construction of  mind maps on paper and digital format (using the software Prezi) as a tool for registration of design process, which it shows the requirement to get deeply in seeking methodologies and tools for a reflexive design teaching.

summary This paper proposes a methodology that assesses in real-time the various impacts of the application of a CAD / CAM logic, to assist the designer in making objective considerations about the efficiency of a given manufacturing logic. A forecast of this nature enables the designer with the power to identify and quantify the strengths and weaknesses of a case versus others, and allows him to detect what are the configurations and processes that have potential to be optimized. The next chapters will show how the use of integration of knowledge-based-methodology (KBM) in the implementation of CAM to systematize the selection of different designs and operations, can improve the construction/fabrication practice depending on the fabrication equipment, material selection and other indicators. The adoption of the above-mentioned methodology is particularly pertinent for decision makers, since it can be deployed in a variety of different processes. It harvests information to compare and optimize the manufacture outline, and supports the screening and assortment of appropriate tool paths or combination of fabrication tools based on environmental/cost data, user-specified requirements and context characteristics.

summary The main goal of the project is to generate a framework for a knowledge-based-methodology (KBM) within a parametric software. This is accomplished through a combination of the design software and robot simulation with real-time assessment based on a process-flow-diagram (PFD) structure that compiles the main environmental parameters of the manufacture process. The intention is to create a methodology to directly report the impact of the manufacture of a specific design, from the materials embodied energy to the energy consumption of each step. This framework provides valuable information which may monitor the developer towards alterations to increase the CAD/CAM performance. In the context of this paper, this methodology was applied in the conceptual design and manufacture of a housing structural insulated panel prototype using parametric design software and robotic equipment. The purpose is to generate a quasi-automated design process linked with real-time analysis and assessment of the fabrication process, offering real time environmental and cost analysis of a panelized structure house manufacture logic. The suggested methodology outputs information to compare and optimize the manufacture outline, and supports the screening and assortment of appropriate tool paths or combination of fabrication tools based on environmental/cost data, user-specified requirements and context characteristics.

summary Technology has been an obvious solution to the increasing complexity of the built environment. As the number and specificity of use requirements increases, designers, clients and managers tend to segment the overall problem to manageable aspects only tentatively linked to each other. As a result, aspects such as ventilation and lighting tend to rely more on mechanical means than on the affordances of the overall design. Ironically this increases the complexity and opacity of the built environment probably to a greater extent than rules, regulations and requirements. The paper presents a review of available computational methods and techniques that aim at a more coherent approach by supporting integration of (day)lighting into architectural designing. It proposes that the two main courses of further action are the improvement and updating building regulations, and the combination of quantitative knowledge of good, existing daylight designs with advanced simulation-based analyses of early design proposals. Improvements in daylighting design and the integration of daylighting in design solutions depend primarily on design guidance based on the coordinated development and thorough understanding of usable measures such as the Daylight Factor, the Daylight Performance Index and function factors. A major prerequisite to both simulation and design guidance are robust and detailed geometrical 3D models that accommodate both the input and the output of design actions and transactions.

summary In the last decade Computational Building Performance Simulation (CBPS) has acquired the reputation of a solid analytical method. However, this reputation relies mostly on the admittedly advanced and robust theoretical and algorithmic basis of performance simulation techniques. On the practical side, building simulation has yet to live up to expectation. The main reason is that simulation use is not as widespread as it should. Applications are mostly academic, mainly validation studies. This has led us to the assumption that the applicability and usability of performance simulations require additional components that link them more closely to design processes and facilitate their integration in everyday design activities. In this paper we present the results of research into a working method for location-specific daylight simulation. Our method is based on the satisfication of a number of requirements common to many types of CBPS: validated simulation algorithms, flexible, fast calibration by means of real-world measurement, multiyear, location-specific environmental data, and support of both measured and mathematical environmental data models.

summary This paper examines two theories regarding the design principles of Byzantine churches through the use of 3D computer models produced by a programming language that allows the manipulation of the models parametrically to derive several instantiations by varying key dimensions. This geometry-based programming language, which is part of a larger solids modeling program, proved to be an excellent tool for determining the scope and the limiting cases of each of the two theories and the degree of their interrelationship.

summary Byzantine church design depended heavily on natural light which was used for evocative purposes. The orientation of the main axis of the church, the form of the apse and the location and size of its windows are affected by the need for sunlight to shine at the altar on a desired time and for a certain duration. Until now the process of accurately taking account of all the above parameters has been rather difficult and tedious. This paper illustrates the use of digital tools both for the analysis of the geometry of existing apse designs and the parametric generation of new ones. A sophisticated computer program was used to calculate sun angles during the Byzantine period incorporating calendar changes. In addition, Bentley System’s Generative Components software was used to construct a parametric model that allows the user to define the geometric conditions and parameters of the apse. The software would then iterate through multiple solutions to satisfy the desired conditions as well as allow the user to change the conditions at will. The tools were used to discover the geometry of the apse of the Byzantine church of Hagia Sophia in Constantinople and to analyze the apse of the Post-Byzantine church of the Xeropotamou monastery on Mount Athos in Greece. The paper concludes with a discussion of the role of parametric tools for architectural analysis and the generation of possible design solutions.

summary This paper is a contribution to the domain of computer tools for architectural and archeological restitution of ancient buildings. We describe an application of these tools to the modeling of the 14th century AD. Thermae of Constantin in Arles, south of France. It was a diploma project in School of Architecture of MarseilleLuminy, and took place in a context defined in the European ARELATE project. The general objective of this project is to emphasize the archeological and architectural heritage of the city of Arles; it aims, in particular, to equip the museum of ancient Arles with a computer tool enabling the storage and consultation of archaeological archives, the communication of information and exchange by specialized networks, and the creation of a virtual museum allowing a redescription of the monuments and a “virtual” visit of ancient Arles. Our approach involves a multidisciplinary approach, calling on architecture, archeology and computer science. The archeologist’s work is to collect information and interpret it; this is the starting point of the architect’s work who, using these elements, suggests an architectural reconstruction. This synthesis contains the functioning analysis of the structure and building. The potential provided by the computer as a tool (in this case, the POV-Ray software) with access to several three-dimensional visualizations, according to hypotheses formulated by the architect and archaeologists, necessitates the use of evolutive models which, thanks to the parametrization of dimensions of a building and its elements, can be adapted to all the changes desired by the architect. The specific contribution of POV-Ray in architectural reconstruction of thermae finds its expression in four forms of this modeling program, which correspond to the objectives set by the architect in agreement with archeologists: (a) The parametrization of dimensions, which contributes significantly in simplifying the reintervention process of the architectural data base; (b) Hierarchy and links between variables, allowing “grouped” modifications of modelized elements in order to preserve the consistency of the architectural building’s morphology; (c) The levels of modeling (with or without facing, for example), which admit of the exploration of all structural and architectural trails (relationship form/ function); and, (d) The “model-type,” facilitating the setting up of hypotheses by simple scaling and transformation of these models (e.g., roofing models) on an already modelled structure. The methodological validation of this modeling software’s particular use in architectural formulation of hypotheses shows that the software is the principal graphical medium of discussion between architect and archaeologist, thus confirming the hypotheses formulated at the beginning of this project.

title Discrete Surfacesfor Architectural Design
source Nashboro Press 2007
summary Geometric problems originating in architecture can lead to interesting research and results in geometry processing, computer aided geometric design, and discrete differential geometry. In this ar- ticle we survey this development and consider an important problem of this kind: Discrete surfaces (meshes) which admit a multi-layered geometric support structure. It turns out that such meshes can be el- egantly studied via the concept of parallel mesh. Discrete versions of the network of principal curvature lines turn out to be parallel to ap- proximately spherical meshes. Both circular meshes and the conical meshes considered only recently are instances of this meta-theorem. We dicuss properties and interrelations of circular and conical meshes, and also their connections to meshes in static equilibrium and dis- crete minimal surfaces. We conclude with a list of research problems in geometry which are related to architectural design.

summary The prime objective of this study is the analysis and the understanding of the underlying architectural principles (ideas) behind the particular seminar work that they have been given. Although this study is limited to one building its real significance lies not only in what it tells us about it, but also what it reveals about architecture itself. By distilling and comparing these buildings and stripping away the circumstances of their creation, we are shown universal principles of their design. This universality invites comparison to other buildings far removed in time and place.

summary This paper presents and discusses results related to a full-scale responsive urban lighting experiment and introduces a light design methodology inspired by reactive control strategies in robot systems. The experiment investigates how human motion intensities can be used as input to light design in a reactive system. Using video from 3 thermal cameras and computer vision analysis; people’s flow patterns were monitored and send as input into a reactive light system. Using physical as well as digital models 4 different light scenarios is designed and tested in full-scale. Results show that people on the square did not engage in the changing illumination and often they did not realized that the light changed according to their presence. However from the edge of the square people observed the light patterns “painted” on the city square, as such people became actors on the urban stage, often without knowing. Furthermore did the experiment showcase power savings up to 90% depending on the response strategy.

summary This paper presents a mixed-method research design investigation that integrates a Hybrid Digital-Analog Software-Hardware protocol referred to as the No Keyboard, No Mouse (NK-NM) platform. The NK-NM process uses both theoretical and applied research mechanisms to measure its influence on architectural design decision-making, knowledge exchange, student learning, aesthetics, and user experience in the context of an undergraduate architectural design studio. Observing a recognized gap in the current digital architectural design environments this paper details how the NK-NM protocol bridges this gap through an instructed hierarchical design process, customizable physical interface, and iterative simulation-based feedback loop.

summary 'Design Dialogues: one' was the first in an occasional series of discussion meetings on design theory sponsored by the Design Research Society. The objective of the meeting was to explore the reasons for the apparent lack of progress in design research over the last decade and in particular whether the search for an atemporal, acultural, domain independent theory of design is a reasonable or realistic goal. The meeting was held on the 17th of May at the Department of Computer Science, University College London and attracted more than 40 participants from a wide variety of disciplines including the arts, architecture, computer science, engineering and business studies.In an attempt to continue the debate in the wider design research community, we have produced the following summary of the presentations and discussion period together with some concluding remarks. While we have made every effort ensure that summaries of the speakers presentations and the discussion are accurate, readers should be aware that they are based on notes taken during the meeting itself and consequently reflect a particular interpretation of the proceedings. However, for those who wish to follow up the ideas presented by the speakers in more detail, we have included a short list of references to relevant work at the end of this meeting summary.

summary The paper doesn't intend to provide relevant innovations in the field of processing program designs or software technology. Although I respect other opinions, I feel that the uncontested aid which using computers to teach architecture means should preferably and primarily be oriented towards searching for ways to better transmit and explain what we have, up to now, been teaching through other means.

However, the novelty and advantages of reccuring to this new instrument should not make us fall into the mistake of letting it be used as a substitute of teachers' and students' work. The computer is simply another instrument; of great potential efficacy, but nevertheless just an instrument.

summary Among the didactic directions of professional training, which Architecture and Urban Science Institute includes, CAAD is set in the courses of Drawing 2 (2nd year of degree course) and Architectural Design 2 (5th year): both ones belong to the didactic turn "compositivo"(drafting + design + project). In the course of Drawing 2, CAAD is presented in a simple, first step way: the most emphasized aspects are technology and description (especially graphic, in 2D, 2.5D, 3D) of objects and places. In the course of Architectural Design 2, CAD experience becomes project appliance and therefore simulation and modelling. The didactic direction, which appears from that, suggests then to consider Drawing as description of objects (in the steps of project process) explored as knowledge, generation,valuation and decision.

summary This paper presents a computational space adjacency analysis method by integrating information and analysis from process flow methods used in the healthcare system with space syntax methods used in architecture. These methods involve similar conceptual properties related to activity, space and flow. However, their implementation in the building programming process is disconnected, and relies solely on experience and expert opinions. The basic approach for the integration was by abstracting these similar properties in the process flow diagram, space connectivity diagram, and justified plan graph into nodes and edges representations. A case study of a clinic that is currently in the construction phase was used to develop the integration procedure and comparison analysis with the actual floorplan.

title Structural Sketcher: Representing and applying well-structured graphic representations in early design
source International Journal of Architectural Computing vol. 3 - no. 1, 75-92
summary Computational drawing support has the potential to improve design support in the early phase. Much work in this area is devoted to input of design information, manipulation, and presentation. Based on a review of current work, we note that among other things, digital drawing tools should be close to the conventions and techniques already used by architects. This is, in principle, possible by processing strokes in a more or less traditional sketch approach, or by offering specialised commands that provide a direct implementation of such conventions. The latter approach is covered by Structural Sketcher. A subset of drawing conventions developed earlier, called graphic units, is adopted within the system. In order to contribute to design support, the application of such graphic units should be fast and intuitive, and the definition of internal relationships should be quick and straightforward. For intuitive manipulation, Structural Sketcher incorporates the "paper and scissors" metaphor, and introduces a novel UI-concept called the KITE. To achieve an easy and fast maintenance of relationships, a graph based on anchor-points is built-up on the fly. Performance of the system has been tested on a quantitative and qualitative basis. The system shows the benefit that graphic units can bring to drawing support, and how these can be implemented. To conclude, limitations and further work are discussed.

title STRUCTURAL SKETCHER: A TOOL FOR SUPPORTING ARCHITECTS IN EARLY STAGES
source PhD thesis, Technische Universiteit Eindhoven, The Netherlands
summary Traditionally, architects use pen and paper for the early stages. Architects have great expertise in drawing, their use is simple and has low overhead, and a high precision is not required, and even counterproductive. The last decades many systems to support architects have been developed. These are primarily suited for the production of final technical drawings. Architects do not use them in the early phases, because they do not offer the freedom, speed, and ambiguity needed there. Nevertheless, the use of a computer could offer benefits, such as ease of modification and editing as well as higher level support. The aim of the project described in this thesis was to develop a computer-sketching tool to support architects in the early design stages.

source Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 457-468
summary This paper presents an updated evaluation of an experience of applying computer graphics, virtual reality and Internet resources in the teaching of technical graphics at the University of Brasilia, Brazil. It differs from a previous paper (Pratini, 2004) for the addition of an overview of the course, the context and the new teaching methodology. It is an extended, more detailed paper, which includes examples, and closes with some results of surveys on the didactic material and the methodology. Our motivation for this experiment is the fact that most of the students have a lack of previous knowledge on the basis of drawings, resulting difficulties in both understanding and visualizing technical drawings. In this experiment, we introduced VRML 3D modeling in addition to CAD and regular pencil-and-paper drawings study and practice. To support the learning of this broad knowledge not present in the technical graphics bibliography, we first provided a website with animations and virtual reality resources. Since 2003 we are providing a CD-ROM containing all the former website material which is updated each semester. At the present time, the CD-ROM contains almost all the needed didactic material and software for the one semester technical graphics course. This experience was intended to improve and to support learning in a way that motivates the students, young people who are used to play video and computer games. Classes, website and CD-ROM material were conceived to take advantage of computers´ interactivity and animated resources. The use of computers´ technology and new media to support the learning resulted a new methodology and several new unanswered questions.

summary The 3D SketchMaker Project has developed two prototypes for a gestural 3D sketching system to be used in the earliest phases of the design process. The goal of this ongoing research is to provide architects, and other designers involved in object conception, with a 3D gestural instrument that takes advantage of new virtual reality resources and is more naturalthan using the mouse, less difficult than learning complex software and less abstract than manipulating 2D entities on orthogonal projections. The focus of this project is on the input interface, taking into consideration two factors: First, for many architects and designers, one of the main reasons for not using 3D modeling from the very beginning of the design process is that both current hardware and software are hardly appropriate to do the spontaneous and quick drawings that are used to assist in conceptualizing their objects.

summary The 3D SketchMaker Project has developed two prototypes for a gestural 3D sketching interface in a computer system to be used in the earliest phases of the design process. The goal of this ongoing research is to provide architects, and other designers involved in object conception, with a 3D gestural instrument that takes advantage of new virtual reality resources and is more natural than using the mouse, less difficult than learning complex software and less abstract than manipulating 2D entities on orthogonal projections. The focus of this project is on the input interface, taking into consideration two factors: First, for many architects and designers, one of the main reasons for not using 3D modeling from the very beginning of the design process is that both current computer hardware and software are hardly appropriate to do the spontaneous and quick drawings that are used to assist in conceptualizing their objects. Second, three-dimensional modeling packages use two-and-three dimensional elements, in a 3D environment, but usually employ 2D input devices that are not appropriate to work in 3D environments, such as mice or pen-and-tablets. The 3D SketchMaker was conceived to take advantage of a natural tendency most people have in using gesture as an aid to language when trying to describe the shape, form or volume of objects. The system is intended to assist or replace the first 2D drawing steps in the design process, generating rough 3D sketches that can be refined later. It is, in essence, a 3D modeling system (a prototype, at this time) directed to do sketching with hand movements and gestures in a virtual reality environment.

summary The process of sketching can support the sort of transformational thinking that is seen as essential for the interpretation and reinterpretation of ideas in innovative design (Suwa 2003). In this paper, the initial outputs and findings of an ongoing project called Design Synthesis and Shape Generation are described based on experimental investigations of the mechanics of sketching from practicing architects and industrial designers as they responded to a series of conceptual design tasks. Preliminary analyses of the experimental data suggest that the interactions of designers with their sketches can be formalised according to a finite number of generalised shape rules. These rules formalise the transformations and reinterpretation of shapes for example through deformation or restructuring.

summary This paper discusses the designer’s role in the process of computer interfaces production. Understood as virtual spaces, they polarize the user’s attention as they are the vague and little known territory in which user and system can, finally, communicate. For so far, a parallel will be established between the architect’s education as a designer of concrete spaces, whose wideness qualifies him to dialogue with specialized engineers about technical construction matters, and the need of being formed a (new?) professional interface designer, able to dialogue with the experts of technological aspects concerning the building of virtual spaces. The paper also analyses the education of nowadays’ interface designers - computer scientists, web designers, writers, artists, architects and information architects -, searching to identify ways of potentializing their performance.

summary A method is proposed for architectural construction of virtual spaces by using structures of mnemotechniques. Defined as belonging to the mind, it is proposed to conceive the virtual space through architectural methods by adding the use of Mnemonics, which is the art and technique of developing and strengthening the memory. The memorization process itself becomes central in the process of constructing the virtual context. Introducing examples in history and recent art applications in virtual reality, this paper proposes the introduction of mnemotechniques for the architectural spatial structuring of the virtual space.

The discussion draws on relations between the auto-organization model and the use of mnemonic techniques. These techniques of data organization – related to spatial structures, may constitute the informational organization rules: structuring the flow, storage and access, making auto-organization possible [Full paper in Portuguese]

summary Information and communication technologies bring together methods of organizing complex activities while questioning traditional ways of working, inviting to use complex approaches when it comes to design process, based on the fact that the media has the potential to alter the perceptions of whole factors involved. It enables the creation of networks, the rethinking of working methods, allowing an even more effective interaction between different actors and their activities. The starting point for the experimental exercise “Abrigo Mínimo” was to discuss a different approach of understanding the way architectural student design by including questions of context. It is proposed that, to understand the design process complexity, they should have a vision of site, subjects and design interrelations as processes rather than products and a conception of it as fields of relations rather than as arrangements of objects. This posture would change radically the students’ way of designing, providing a kind of orientation to act. [Full paper in Portuguese]

summary Environmental design implementations are generally applied within limited and specialised areas of environmental design making them difficult to use intuitively by designers (Maneesatid and Szalapaj, 2003). Building simulations have mostly focused on accurate parameters and physical properties of building elements. Such tools typically require numerous numerical data which is often only accurately known in the detail design stages. Conventional environmental building design systems (EBS) have typically required highly experienced users who are familiar with extensive qualitative input and output requirements. A successful architectural design solution that is both energy efficient and environmentally friendly, cannot be obtained simply by additively combining a set of discrete specialist analyses. A move towards better architectural design with environmental considerations can be achieved by allowing designers themselves to express relationships between salient environmental parameters that can subsequently be analysed in integrated ways. This presentation is concerned with the issues involved in developing a quick and intuitive interface for expression of relationships between environmental parameters.

summary Sunlight and skylight are rarely rendered correctly in computer graphics. A major reason for this is high computational expense. Another is that precise atmospheric data is rarely available. We present an inexpensive analytic model that approximates full spectrum daylight for various atmospheric conditions. These conditions are parameterized using terms that users can either measure or estimate. We also present an inexpensive analytic model that approximates the effects of atmosphere (aerial perspective). These models are fielded in a number of conditions and intermediate results verified against standard literature from atmospheric science. Our goal is to achieve as much accuracy as possible without sacrificing usability.

Recently, Lipton and Tarjan presented a brilliant but extremely complex point location algorithm which runs in time O(log n) on a data structure using O(n) storage. This paper presents a practical algorithm which runs in less than O(log 2n) comparisons on a data structure which uses O(n log n) storage, in the worst case. The method rests crucially on a simple partition of each edge of G into O(log n) segments

summary In an age dominated by the Internet and electronic media it is becoming increasingly clear that our perception of space is also undergoing a profound transformation. The author takes the reader on a fascinating journey, revealing who has played a part in this transformation. Avant-garde artists, including Boccioni, Duchamp and Kandinsky, the architect Gropius, philosophers such as Wittgenstein and psychoanalysts like Carl Gustav Jung all contributed to this development. Today, our awareness of traditional architectural space is changing; buildings are being rendered transparent, fleeting and intangible, enhanced by virtual potential. The author looks at works by Rem Koolhaas, Jean Nouvel, Frank Gehry, Zaha Hadid, James Wines, Daniel Libeskind, Toyo Ito, which reflect building in an age of virtual realism.

With the advent of animation and advanced methods of real time video presentation seem to have substantially upgraded the architects' tool chest. Significant advances have been made recently in bringing animation capabilities to the architectural desktop. To discover the level of integration of animation and multimedia in architectural firms, a series of interviews were conducted at five large Los Angeles firms. The interviews were structured with open-ended questions to allow the firms to emphasize their interests and capabilities.

The course tests the application of Reverse Engineering (RE) in a team configuration, Hot-Swapping (HS), and precision modelling of complex geometries with minimal programming/scripting input, taking in consideration the limited resources common to small-scale architectural practices. Reverse Engineering particularly enables students to extract information building assembly and executed details with precision, based on existing documentation. It is conducted in teams not only to emphasize and investigate efficiency of protocols but also to observe problems in developing threads in digital modelling. Hot-Swapping identifies the principle of replacing components of a building during active design processes without altering its general appearance. As a teaching methodology, it allows the investigation of required modelling accuracy, creation of prototypes and various versions of assembly alternatives. The current paper focuses mainly on 1) engaged procedures in Reverse Engineering, 2) the educational aspects of such an approach, and 3) the advantages and disadvantages of conventional tools in a collaborative modelling exercise.

title Estimating camera orientation from vanishing point location during sewer surveys
source Automation in Construction 5 (5) (1997) pp. 407-419
summary A method is presented by which camera orientation relative to the pipe axis may be recovered from a single frame of a survey video of a small-bore brick sewer. If it can be fully recovered, the pipe axis provides part of a frame of reference within which 3D descriptions of sewer shape may be expressed. The concept of the vanishing point is introduced and it is shown that the vanishing point position supplies information about the relative orientations of the camera and pipe axes. A method for the automatic detection of vanishing points is presented and used to analyse the camera motion underlying a number of sewer survey videos. The technique might form an active part of a more comprehensive image understanding system recovering pipe shape from survey videos and/or be used as an experimental tool during the design of such a system.

source II Seminario Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings / ISBN 978-97190-0-X] Mar del Plata (Argentina) 9-11 september 1998, pp. 300-309
summary A method to develop skills using digital techniques in architectural and design fields is proposed. Recursive procedures in successive cycles of abstraction are used applied for the urban layout design process. Each configurational cycle (master plan, urban modules, buildings, habitational units) is separated and exaggerated to face the process with pedagogical goals. Urban factors that conform the city are identified in order to classify repetitive urban problems. A patch of the city, in which a master plan is developed, is isolated and is submitted the measurable tests related to the Architectural and Design projecting process, enfatizating the following aspects., its systemic structures, its geometry and its growing. Alometric concepts and growing form analogies are used as scale control method in transformations and in recursive cycles. Based in two potentially recursive theories, fractals and tessellation's theories, a pedagogic procedure oriented to the use of tessellations is proposed using CAD systems tools.

title Identifying and Quantifying the Company-Wide Benefits of CAD Within the Structure of a Comprehensive Investment Program
source Computer Aided Design. Butterworth & Co. Pub., February, 1985. vol. 17: pp. 3-8 : ill. flow charts
summary This paper discusses the costs and benefits associated with introducing CAD. It is shown that by suitably defining the terms involved, all the so-called 'intangible benefits' can be quantified and used within a rigorous financial evaluation. Because 45 specific factors must be considered if a genuine investment appraisal of CAD is to be performed, a computer program has been specifically written to overcome the difficulties normally associated with the DCF evaluation of major projects. The results from the program demonstrate that not only are the benefits of CAD company-wide, but that when these benefits are quantified, the economic case for CAD is greatly strengthened. The problem of CAD systems being regarded as nothing more than a 'drawing office tool to make draftsmen redundant' is overcome. In particular, the use of the program within a number of major companies reveals that CAD systems not only give a much greater potential return on investment than has been suggested by previous authors, but that the greatest benefits accrue in areas outside the drawing office. This is illustrated by a case study

source Proceedings of the 2002 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-11-X / Pomona (California) 24-27 October 2002, 446 p.
summary The 2002 ACADIA conference finds digital tec_nology ubiquitous as the Association for Computer Aided Design in Architecture moves into its third decade. The organization of ACADIA is on the threshold of restating its mission. After 20 years, many of the organization’s initial objectives have been achieved. ACADIA members have been instrumental in the development of design software, and in bringing computers and digital technology into architectural practice and design school curriculum. At first, ACADIAns faced the debate over the appropriateness and utility of digital technology in the disciplines of architecture, planning and building science. Today the use of computers and information technology is widely accepted by architects and CAAD and digital technology have brought profound change to design practice. The debate in ACADIA has long since moved from "should we use this technology" to "how", "for what" and "why". Now that many practitioners, learning institutions and professional organizations have taken up the call, ACADIA must restate its mission, if it wishes to remain “distinct”. This does not mean that the work of ACADIA is complete. Much remains to be done and much more needs to be improved. ACADIA’s Mission Statement places particular focus on “education and the software, hardware and pedagogy involved in education.” And “(t)he organization is also committed to the research and development of computer aides that enhance design creativity, and that aim at contributing to the construction of humane physical environments.” These are the areas that continue to evolve, grow and provide for ACADIA’s continued relevance. The ACADIA 2002 conference theme reflects the state of digital technology’s application to the discipline, as much as it refers to ACADIA’s future. With the general acceptance of digital technology and CAAD, we have arrived at a place where the work of great interest and relevance lies in the space between what is digital and what is analog. The environments of real space and cyberspace have in a very short time become so intertwined that the space between real and virtual (not to be confused with reality and fantasy) is becoming indistinguishable. You cannot eat, travel, use public utilities, bank, shop, vacation or recreate without at the very least coming into contact with or passing through information space. The landscape between these two environments has become a cultural phenomenon for those societies with access to the Internet and information networks. And while the computer and World Wide Web have empowered individuals, the collective impact of the technology holds all the potential and problems that similarly emerged in other technology induced landscapes. Consider this last point in the context of ACADIA’s stated mission to “enhance design creativity while contributing to the construction of humane physical environments.” And you can see why many of the 260 initial submissions to this conference were in the area of design artifacts and design methodology, providing evidence that ACADIA’s mission remains relevant and in accord with the trends of research and professional creative activity.

summary The readers of this journal no doubt have a strong understanding of the variety and range of modeling and imaging tools available to architects and designers. Clearly the ability to use these tools often requires a substantial time investment to produce usable results. Modeling, constructing scenes, adjusting lights and materials, setting up camera angles and so forth can often amount to several hundred person-hours. Even with the shift to digital media in professional practice, the time required to model and create scenes for presentation purposes not to mention for design study and analysis is frequently not budgeted.

source ACADIA Quarterly, vol. 19, no. 1, pp. 15-16
summary After having conducted a Digital Media based design studio at Cal Poly for six years, we have developed a body of experience I feel is worth sharing. When the idea of conducting a studio with the exclusive use of digital tools was implemented at our college, it was still somewhat novel, and only 2 short years after the first VDS- Virtual Design Studio (UBC, UHK et.al.-1993). When we began, most of what we explored required a suspension of disbelief on the part of both the students and faculty reviewers of studio work. In a few short years the notions we examined have become ubiquitous in academic architectural discourse and are expanding into common use in practice. (For background, the digital media component of our curriculum owes much to my time at Harvard GSD [MAUD 1989-91] and the texts of: McCullough/Mitchell 1990, 1994; McCullough 1998; Mitchell 1990,1992,1996; Tufte 1990; Turkel 1995; and Wojtowicz 1993; and others.)

source Architectural Information Management [19th eCAADe Conference Proceedings / ISBN 0-9523687-8-1] Helsinki (Finland) 29-31 August 2001, pp. 192-200
summary Design educators attempt to train the eyes and minds of students to see and comprehend the world around them with the intention of preparing those students to become good designers, critical thinkers and ultimately responsible architects. Over the last eight years we have been developing the digital media curriculum of our architecture program with these fundamental values. We have built digital media use and instruction on the foundation of our program which has historically been based in physical model making. Digital modeling has gradually replaced the capacity of physical models as an analytical and thinking tool, and as a communication and presentation device. The first year of our program provides a foundation and introduction to 2d and 3d design and composition, the second year explores larger buildings and history, the third year explores building systems and structure through design studies of public buildings, fourth year explores urbanism, theory and technology through topic studios and, during the fifth year students complete a capstone project. Digital media and CADD have and are being synchronized with the existing NAAB accredited regimen while also allowing for alternative career options for students. Given our location in the Los Angeles region, many students with a strong background in digital media have gone on to jobs in video game design and the movie industry. Clearly there is much a student of architecture must learn to attain a level of professional competency. A capacity to think visually is one of those skills and is arguably a skill that distinguishes members of the visual arts (including Architecture) from other disciplines. From a web search of information posted by the American Academy of Opthamology, Visual Acuity is defined as an ability to discriminate fine details when looking at something and is often measured with the Snellen Eye Chart (the 20/20 eye test). In the context of this paper visual acuity refers to a subject’s capacity to discriminate useful abstractions in a visual field for the purposes of Visual Thinking- problem solving through seeing (Arnheim, 1969, Laseau 1980, Hoffman 1998). The growing use of digital media and the expanding ability to assemble design ideas and images through point-and-click methods makes the cultivation and development of visual skills all the more important to today’s crop of young architects. The advent of digital media also brings into question the traditional, static 2d methods used to build visual skills in a design education instead of promoting active 3d methods for teaching, learning and developing visual skills. Interactive digital movies provide an excellent platform for promoting visual acuity, and correlating the innate mechanisms of visual perception with the abstractions and notational systems used in professional discourse. In the context of this paper, pedagogy for building visual acuity is being considered with regard to perception of the real world, for example the visual survey of an environment, a site or a street scene and how that visual survey works in conjunction with practice.

summary Architectural design in this ‘digital age’ is becoming more embedded within virtual computer aided design environments. This study expands this virtual design environment back into physical realms through the use of microelectronic wind sensing technology. An interactive and flexible wind sensing system (open source minia- ture portable wind tunnel and wind sensors) was evaluated for its abil- ity to simulate and measure the effects of wind. Physical models of four high-rise buildings were constructed to evaluate ground level pe- destrian comfort resulting from the degree of torsional twist in the building form. The model investigation formed a case study for evalu- ating of the low-cost miniature portable wind tunnel and microelec- tronic wind sensing system for comparison with an industrial aeronau- tical wind tunnel and high precision wind sensors.

title The Role of Rest Frames in Vection, Presence and Motion Sickness
source University of Washington, HIT-Lab
summary A framework is presented for comprehending partly participants' spatial percep- tion in virtual environments. Speci c hypotheses derived from that framework in- clude: simulator sickness should be reducible through visual background manipula- tions; and the sense of presence, or of \being in" a virtual environment, should be increased by manipulations that facilitate perception of a virtual scene as a perceptual rest frame. Experiments to assess the simulator sickness reduction hypothesis demon- strated that congruence between the visual background and inertial cues decreased reported simulator sickness and per-exposure postural instability. Experiments to assess the presence hypothesis used two measures: self-reported presence and visual- inertial nulling. Results indicated that a meaningful virtual scene, as opposed to a random one, increased both reported presence and the level of inertial motion re- quired to overcome perceived self-motion elicited by scene motion. The simulator sickness research implies that visual background manipulations may be a means to reduce the prevalent unwanted side-e ects of simulators. The presence research intro- duces a procedure, possibly based on brain-stem level neural processing, to measure the salience of virtual environments. Both lines of research are central to developing e ective virtual interfaces which have the potential to increase the human-computer bandwidth, and thus to partially address the information explosion.

summary In the context of a wider inquiry on the integration of material properties and construction processes in computational models, this paper proposes a digital model for fabric formwork panels. Plaster cast in different types of fabric can produce a significant variation of resulting forms. The aim is to investigate whether data retrieved from physical models with 3D scanning techniques can improve the accuracy and efficiency of a simulation based on geometric principles, and better predict the behaviour of cast material in relation to the type of fabric. Setting up the computational model and choosing its parameters and constraints is based on the physical construction process, highlighting the relationship between material and form. As part of the cyclical exchange, evaluation of the digital model with physical testing demonstrates that the simulation can actually be trained by reducing the physical/ digital discrepancies.

summary This paper proposes a simple parametric system to generate an almost complete set of ruled surfaces that may be used to describe building geometry. The major classes of regular, named ruled surfaces can be generated from a limited set of curves. Each of these is shown to be reducible to a transformation of a single standard curve, a helix, and therefore represented by a limited set of six parameters. Six extra parameters can position each surface on a global coordinate system. The representation is designed to be flexible enough to represent both planar and curvilinear forms, producing a description of form from minimal data.

summary This paper presents and discusses a process of transferring the main features of a piece of music such as structure, notes etc., to a primarily spatial construction in architecture. The main objective of this effort was to convert the linearity of time during the hearing of a musical piece into a continuous pathway and an architectural stroll on a given site. To this end, the musical piece is used as a source of data, which, with the use of developed algorithms, are converted into spatial data. A purely instrumental piece, “Air,” from the suite for strings in D major by Bach, provided the source data used in the design of Park D, a section of a Cultural Park in the suburbs of Athens, Greece. The developed algorithms presented in the paper include: a) an algorithm for generating the shape of the path and the space defi ning elements along the path, and b) an algorithm that generates the geometry of four harmonographic structures.

summary This paper presents a novel web-based platform that supports the analysis, integration, and visualization of large-scale and heterogeneous urban data, with application to city planning and decision-making. Motivated by the non-scalable character of conventional urban analytics methods, as well as by the interoperability challenges present in contemporary data silos, the illustrated system – coined SocialGlass – leverages the combined potential of diverse urban data sources. These include sensor and social media streams (Twitter, Instagram, Foursquare), publicly available municipal records, and resources from knowledge repositories. Through data science, semantic integration, and crowdsourcing techniques the platform enables the mapping of demographic information, human movement patterns, place popularity, traffic conditions, as well as citizens’ and visitors’ opinions and preferences about specific venues in a city. The paper further demonstrates an implemented prototype of the platform and its deployment in real-world use cases for monitoring, analyzing, and assessing city-scale events.

summary One of the architectural positions characterized by a visual singularity, it has been that of Zaha Hadid. It will be their particular contribution to the renovation of the architectural representation, through different graphic techniques, analogical and digital, and scale models. Hadid has created its own visual code in which the configuration of the shape and the representation are inseparable, standing out the generating role of the architecture on the part of the representation, beyond its instrumental role, with their peculiar paintings, drawings, scale models and their sophisticated renderings. By analyzing the graphic strategies in relation to the intentions or architectural contents along several proposals, it will conclude showing, through their special graphic style, their contribution to the innovation of the expression of the contemporary project.

title Designing solid objects using interactive sketch interpretation
source Computer Graphics (1992 Symposium on Interactive 3D Graphics), 25(2):117-126, Mar. 1992
summary Before the introduction of Computer Aided Design and solid modeling systems, designers had developed a set of techniques for designing solid objects by sketching their ideas on pencil and paper and refining them into workable designs. Unfortunately, these techniques are different from those for designing objects using a solid modeler. Not only does this waste avast reserve of talent and experience (people typically start drawing from the moment they can hold a crayon), but it also has a more fundamental problem: designers can use their intuition more effectively when sketching than they can when using a solid modeler. Viking is a solid modeling system whose user-interface is based on interactive sketch interpretation. Interactive sketch interpretation lets the designer create a line-drawing of a de- sired object while Viking generates a three-dimensional ob- ject description. This description is consistent with both the designer's line-drawing, and a set of geometric constraints either derived from the line-drawing or placed by the de- signer. Viking's object descriptions are fully compatible with the object descriptions used by traditional solid modelers. As a result, interactive sketch interpretation can be used with traditional solid modeling techniques, combining the advan- tages of both sketching and solid modeling.

source Birkhauser Basel. p. 6
summary In an age dominated by the Internet and electronic media it is becoming increasingly clear that our perception of space is also undergoing a profound transformation. The author takes the reader on a fascinating journey, revealing who has played a part in this transformation. Avant-garde artists, including Boccioni, Duchamp and Kandinsky, the architect Gropius, philosophers such as Wittgenstein and psychoanalysts like Carl Gustav Jung all contributed to this development. Today, our awareness of traditional architectural space is changing; buildings are being rendered transparent, fleeting and intangible, enhanced by virtual potential. The author looks at works by Rem Koolhaas, Jean Nouvel, Frank Gehry, Zaha Hadid, James Wines, Daniel Libeskind, Toyo Ito, which reflect building in an age of virtual realism.

summary This work is based on a digital mapping of actors that build the territorial or conceptual relations between different believes, agents and identities of design. This dynamic map although they are connected with a territory, they are visible on a net that can be based on territory or not. Therefore nodes appear and not necessarily material relationships between them, building networks which will allow data to flow between new neighborhoods. From this framework, the project’s next step is to produce an interactive prototype map of design’s field in the city of Buenos Aires.

summary In this paper we present a hierarchical decision support system for the allocation of organisations to available buildings, and for the allocation of employees of an organisation to the work units of a building. For both allocation problems a mathematical model and optimisation algorithm is developed, taking into account the relevant criteria, such as the extent to which the allocated floorspace is in accordance with the standards, and the extent to which departments are housed in connecting zones of a building. The decision support system is illustrated by two practical applications.

summary The introduction of digital technologies for making models, prototypes, and buildings or building parts in the architectural research, teaching, and practice is a reality today. However, the process is sometimes jeopardized by the lack of clarity regarding the use of certain terms still found in the literature. The goal of this paper is to contribute for overcoming this flaw by providing such a clarification and a possible categorization of the available technologies. The term digital materialization is proposed as a general term to designate all the production technologies available for making physical artifacts.

Connecting two events called Road Show and Workshop, the paper shows the methods, processes and solutions achieved throughout different activities and its effects on the use of Digital fabrication and rapid prototyping as a design and materialization tools. In such case, it is a good example on how to spread the news and provide a starting point to make people more aware and train them to become future users of these technologies. The materialization of the results are shown.

source Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 431-437
summary Applications of information technology (IT) in the architectural profession have greatly increased in the past decades, ranging nowadays from concept design to automated construction. There are countless applications in the architecture practice that go well beyond representation, such as BIM software, generative design systems, and rapid prototyping and fabrication. For this reason, IT has been a frequent graduate research topic. In the present research academic graduate theses that dealt with IT in architecture since 1999 were surveyed and categorized, with the purpose of comparing the topics, applications and methods that are studied in Brazil and abroad. We hope that the differences found will help Brazilian architecture schools to update their IT curriculum, overcoming old prejudices against the use of computers in the creative phases of design.

summary The impact of new technologies as rapid prototyping and digital fabrication used throughout the design process has been a very discussed subject mainly in architecture teaching. Together with this discussion, the introduction of parametric software has a great importance in getting new perspectives and design innovation. In attempting the association of these two lines, the development of a roof project was one of the results of a subject in the postgraduate program at State University of Campinas, Brasil. The design process used those technologies, which allowed the analysis of the impacts they might have during each phase of the design process.

summary A primary aim of the Light Table project was to see if a combination of the optical laser disc, local area networks, and interactive videographic workstation technology could bring a major visual collection, (such as the Rotch Visual Collections of the Massachusetts Institute of Technology), to a campuswide population of undergraduate users. VIS (Visual Information System) is the name being given to the new genre of information technology. Much research and development effort is currently being applied to areas where the image has a special significance, for example in architecture and planning, in graphic and fine arts, in biology, in medicine, and in photography. One particular advance in the technology of VIS has been the facility to access visual information across a distributed computer system via LAN (Local Area Networks) and video delivery systems, (such as campus TV cable). This advance allows users to retrieve images from both local and remote sources, dispatching the image search through the LAN, and receiving the images back at their workstation via dedicated channels on the campus TV cable. Light Table is the title of a system that acts as a computer-based interactive videographic interface to a variety of visual information systems described in the body of this paper. It takes its name from the traditional, back- lit, translucent light table that lecturers use to assemble and view collections of slides for talks and seminars. The component of Light Table which is being reported in greatest detail here, a software outcome called Galatea, is a versatile and robust system capable of controlling video devices in a networked environment.

source Department of Architectural and Design Science, University of Sydney
summary This thesis describes an expert system for designing the layout of a single-family house using the Espansiva building system introduced by Jorn Utzon. The expert system uses two systems that are already available; the BUILD expert system shell as an automated reasoning system and the Eagle 3D modeler system for producing graphical output. Both programs run under the UNIX operating system on SUN microcomputers. The integration of BUILD, which is written in Prolog, with Eagle using one of the Eagle commands called 'weasel' is a major part of the implementation of the system.

summary Computation of the union, intersection, and difference of n- dimensional objects plays a central role in several computer- aided geometric design problems. An algorithm for computing these operations that uses a boundary classification technique is presented here. The algorithm is recursive in structure, with the recursion being on the dimensions of objects dealt with at each stage. The representation treats all entities as objects, making no distinction between faces, edges or vertices. The objects produced are 'regularized,' that is, there are no degenerate boundaries such as dangling edges. The sample application given involved hidden-surface removal

summary This paper builds towards the argument that pedestrian traffic in the city can be successfully simulated with agent-based computational models if pedestrians' movement patterns are appropriately studied first. Furthermore, such simulation models, when finely calibrated and supported by onsite observations, allow planners to evaluate different urban design scenarios.We present a pilot study carried out in the centre of Tallinn, and discuss a way of how pedestrian movement simulations can be conceived. In the pilot study we recorded some 120 traces of pedestrians' movement and developed a prototype of an agent-based computational model to simulate this movement. Additionally we investigated the possibility of including solar analysis into the computational model. Already this short exercise offered us some interesting insights into how certain spatial qualities and features can drive pedestrian traffic making urban walkers to verge off the shortest routes. The pilot study was carried out in the context of the High Street project [1] for turning the centre of Tallinn into more pedestrian friendly area by redesigning urban space, calming vehicular traffic and creating new opportunities for businesses to flourish.

summary This paper reports on the computational modelling research investigating spatial organisations often associated with unplanned settlements. Such spatial agglomerates are composed of several co-located but autonomous units (agents) that share common facilities and infrastructure (e.g. circulation). Depending on the context, units in the agglomerate represent individual dwellings, apartments or abstract spatial geometry. The paper presents early prototype models that can be interpreted at various scale, and a computational model for generating organic settlement layouts. The originality of the research resides within a new multi-agent algorithm for creating spatial organisations. The agglomeration process benefits from two distinct generative design strategies – self-organisation and adaptive development strategy. While the self-organisation accounts for the emergence of the global structure in the agglomeration, the adaptive development strategy ensures that the basic environmental and spatial requirements of each individual unit are satisfied.

title Spatial Simulations with Cognitive and Design Agents
source International Journal of Architectural Computing vol. 5 - no. 1, pp. 100-114
summary Agent based design systems could provide useful decision help for architects working on spatial planning tasks that involve large number of actors or deal with complex urban situations. These systems are especially helpful in bridging the gap between concrete design proposals and high-level design abstractions such as frequency and flow diagrams. Every attempt to use computational design agents in the planning process will automatically raise many fundamental issues about spatial perception and representation of the environment. The paper discusses these issues in the light of some recent agent based simulations. Two case studies are presented in order to demonstrate different uses of computational agents in urban design. The first study shows how a simple agent-based design system placed in an urban context becomes a creative production tool. The second one reveals analytical capabilities of an agent system in urban environments.

keywords The following research, depicts a theoretical model of producing architectural spatial layouts. This is based on a more Biological View of Architectural space and concerns it self with the way that organisms (and in-turn we) perceive and interact with our environments. The model presented here emanates from a range of different fields and not only architectural theory and design. This research touches upon the fields architecture, mathematics, biology, behavioural psychology and has been inspired and draws heavily on the work done by Tim Ireland, as well as some of the work of Gregg Lynn and Alessandro Zomparelli, as well as the theoretical work of Uexküll and Kwinter. The model has began from a simple coding exercise and has developed into a detailed organism that acts and interacts with its environment. The end results present a bottom-up approach to spatial architectural layouts that are defined by the way the organism design interacts with given spatial qualities and other similar organisms with other given spatial qualities. The results retrieved from the coding exercises represent a more abstract -at this point- representation of space and have been slightly manipulated in other Modelling Packages to receive a clearer image.

source Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 429-438
summary Designers interact with a wide range of design tools, in a variety of ways, in order to support their work. Any attempt to produce digital tools aimed at supporting ideation raises the question of the kind of information considered account and what is appropriate to the needs and expectations of designers. We developed and implemented an assessment method for digitally supported conceptual design based on reflective conversation, flow, cognitive ergonomics and activity theory. Our approach opens up the evaluation spectrum to include parameters beyond performances factors for conceiving new digital design tools. This assessment approach considers user (the designer), action (ideation) and object (the tool) in the ideation process, namely the designer’s experience interrelated to the needs of the task and the characteristics of the tool. In this paper we present the results of several research protocols in which we observed, analyzed and successively acted upon five different stages of the interface of a design tool as it was being developed, the Hybrid Ideation Space (HIS). Taken as a whole, these results suggest the limits and support of designers’ optimal relationship with an ideation interface.

summary This paper reports on an investigation of the potentials of data utilisation in Architecture from a value generation and business creation points of view, based on an ongoing PhD research by the first author. It is of crucial importance to, first, identify what data actually signifies for Architecture, and secondly to explore how the value obtained through data-driven approaches in other industries could potentially be transferred and applied in our professional context. These objectives have been achieved through a qualitative comparative analysis of various cases. Additionally, the paper discusses the multiplicity of factors which contribute to different interpretations and utilisation of data with reference to various value systems embedded into our profession (e.g. design as ideology, design as profession, design as service). A comparative analysis of the existing data utilisation methods in connection with various value systems provide crucial insights in order to answer the following questions: How can data assess values in architectural design/practice? How can data utilisation give way to the emergence of new values for the profession?

summary The primary limitation of feature-recognition approaches, namely their lack of generalization, has been addressed by the development of feature-extraction techniques. This paper presents a boundary-based procedurefor the sequential extraction of form features from CAD models of objects with planar surfaces. An object is viewed as an initial basic shape that has been iteratively altered through the introduction of form features.Form features are first classified based on their effect in changing a basic shape. Geometric reasoning is then used to obtain generalized properties of the form-features' classes. Finally, form-features' classes aresequentially extracted based on the obtained properties.

source Challenges of the Future [15th eCAADe Conference Proceedings / ISBN 0-9523687-3-0] Vienna (Austria) 17-20 September 1997
summary The paper reports on a study which examines the impact on architectural education needs arising from the changes brought about by the implications of CAD teaching/learning (CAI/CAL). The findings reflect the views of fifty-one (51) architecture schools through a world-wide questionnaire survey conducted in mid 1996. The survey was structured to cover four continents represented by seven countries, namely the USA, UK, Israel, Australia, Canada, Sweden and the Netherlands. Structurally the main findings of this study are summarised under five areas, namely: 1) General Information, 2) Program of Study (curriculum) and CAD course, 3) CAD Laboratories: Hardware, Software, 4) Departmental Current and Future Policies, 5) Multi-media and Virtual Reality. Principally, there were three main objectives for using the computers survey. Firstly, to accommodate a prevalent comprehension of CAD integration into the curriculum of architecture schools world wide. Secondly, to identify the main key factors that control the extent of association between CAD and architectural curriculum. Thirdly, to identify common trends of CAD teaching in Architecture schools world-wide and across the seven countries to establish whether there are any association between them. Several variables and factors that were found to have an impact on AE were examined, namely: the response rate, the conventional methods users and the CAD methods users amongst students, CAD course employment in the curriculum, age of CAD employment, the role of CAD in the curriculum, CAD training time in the Curriculum, CAD laboratories/Hardware & Software, computing staff and technicians, department policies, Multi-Media (MM) and Virtual-Reality (VR). The statistical analysis of the study revealed significant findings, one of which indicates that 35% of the total population of students at the surveyed architecture schools are reported as being CAD users. Out of the 51 architecture schools who participated in this survey, 47 have introduced CAD courses into the curriculum. The impact of CAD on the curriculum was noted to be significant in several areas, namely: architectural design, architectural presentation, structural engineering, facilities management, thesis project and urban design. The top five CAD packages found to be most highly used across universities were, namely, AutoCAD (46), 3DStudio (34), Microstation (23), Form Z (17), ArchiCAD (17). The findings of this study suggest some effective and efficient future directions in adopting some form of effective CAD strategies in the curriculum of architecture. The study also serves as an evaluation tool for computing teaching in the design studio and the curriculum.

summary This paper report on the findings of an empirical case study undertook at Mackintosh School of Architecture/ University of Glasgow study. The study investigated several questions concerning the efficiency of CAD teaching in the design studio in tandem with the CAD learning environment and materials. The study investigated the computer-aided learning in the AutoCAD course at Mackintosh School of Architecture using 35 students at the second year design studio as a vehicle. The methods of this investigation consisted of classroom observations and administering questionnaires to students. The objective of this study was to determine to what extent the CAD learning environment and administered materials were effective in generating supplementary strategies in the design studio. Another objective was to evaluate the computer lab as an optional design studio space in the future settings of schools of architecture. Principally, the study attempted to locate the areas where CAD teaching lapses in relation to the design studio. To arrive at this, several variables were investigated such as the levels of students? performance, attitudes and skills against the learning environment and the overall effectiveness of CAD. The findings of this study may provide some answers to the problems of CAD integration with the design studio. In addition, the questionnaire used in this case study may prove to be helpful as an evaluation tool of CAD courses when integrated with the design studio.

source AVOCAAD Second International Conference [AVOCAAD Conference Proceedings / ISBN 90-76101-02-07] Brussels (Belgium) 8-10 April 1999, pp. 189-204
summary This paper reports on a project that aims to formulate a CAAD program model in Distance Education (Learning/Teaching) framework, to be applied and implemented in future settings at Open Universities worldwide. The methodology used to establish the CAAD program model consisted of a worldwide literature review on the subject of Distance Education and Open Universities. It also involved an assessment of the methods and means used in the delivery of materials to students enrolled at Open Universities, together with an analysis of the current program of study and subject related courses. The methods of this investigation consisted of a comparative analysis between the existing models of teaching process at Open Universities and how it relates to CAAD in architecture schools. The study endeavored to examine several issues that were found to be key factors in any Open University system, namely: the methods of study, program of study, student type/body, academic/degree requirements, and residency/academic calendars. While attempting to establish a conceptual CAAD program model, this study investigated several questions concerning the efficiency of CAAD teaching in Distance Education. One of the study objectives was to determine which factors were mostly needed to effectively integrate CAAD in DE as a new program in Open Universities. In addition, how would these factors affect the design of CAAD courses in OU systems as a new DE program area? And what structural elements would be most affected by these factors? Another objective of this study was to determine to what extent the new CAAD program model in tandem with staff, learning environment, and administered materials would be effective in generating supplementary strategies in the virtual design studio. A third objective was to evaluate the personal computer station as an alternative design studio space in future settings of schools of architecture. Consequently, the principle objective of this study was to develop and establish a CAAD program model to be adopted by Open Universities as a new subject area in DE. Mainly, the study attempted to locate the areas where CAAD teaching excels in the context of virtual design studio of OU system.

title Exploiting Tools of Evaluation to Improve CAAD Teaching Methods. A Case Study of Inter & Intra ECTM Model
source Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 215-230
summary This paper reports on an ongoing research study model into the Evaluation of CAAD Teaching Methods (ECTM) of which a number of resolutions and strategies were attained via an empirical investigation. The first stage of the study findings proposed a framework for the evaluation of architecture courses in tandem with CAAD. The second stage was based on the Inter & Intra ECTM design model as a strategy for acquiring solutions to CAAD problems through the exploitation of CAAD evaluation tools. The ECTM model structure criteria: the Model Concepts, the Operational Context, Dialectic Meanings, Relational Context, Performing Methods and Level of Integration were illuminated. ECTM model has a twofold involvement junctures, which describe CAAD evaluation behaviour. The first involves the evaluator in an interdepartmental comparison of CAAD integration into the curriculum, and/or between schools of architecture. The second engages the evaluator in an intradepartmental study of CAAD integration, and within the institution. The study projected an attempt to validate the Inter & Intra ECTM design model in concert with evaluation. The paper presents an extended description of the objectives, procedures and testing designed for the two abovementioned junctures composing the proposed ECTM case studies. Sequences of methods of data collection employed as a vehicle for the ECTM were Kirkpatrick model, questionnaire survey, observation (using an ECTM checklist) and experimental studies. The paper also explores variables and indicators used, and advances to shed some light on the methods of statistical analysis employment. ECTM model as a tool to attain CAAD effectiveness might redefine the role of collaborators/ team partnerships in CAAD tuition; and induce the level of technology selection and adaptation amongst schools, e.g. tutors and coursework interconnectivity. The ECTM model may also work as a framework of strategies to augment interactivity and positive learning amongst both staff and students.

summary This paper reports on the findings of a study carried out at Glasgow University which proposes a framework for the evaluation of architecture curriculum once integrated with CAAD. This study investigated the evaluation of CAAD teaching methods (CTM) and the effectiveness of CAAD integration (CI) and explored CAAD employment suitability in the design studio, and what influences does it have on the design process tuition using the Kirkpatrick model as a vehicle. The related CAAD evaluation variables investigated were: CAAD Tutor, Course Materials & Contents, Class Environment, Use of Media, Delivery Methodologies, Administrative Briefs, and Overall Effectiveness of CAAD event. Several other variables investigated were the levels of students' performance, attitudes, knowledge, new-stand, creativity and skills. The paper covered briefly some of the findings of the case studies acquired over two years at MSA; both observations and questionnaire surveys were used as methods of data collection. Evaluation deficiency postulates the weaknesses of CAAD in architecture schools. Evaluation of CAAD tuition should be a fundamental approach to address CAAD integration efficiency and problems, to achieve effectiveness and productivity amongst architecture schools.

title The Impact of CAL Strategies on CAD
source CAADRIA ‘97 [Proceedings of the Second Conference on Computer Aided Architectural Design Research in Asia / ISBN 957-575-057-8] Taiwan 17-19 April 1997, pp. 475-489
summary This paper reports on a two fold study, which examines the impact of CAL on CAD and architectural education, and evaluates the overall effectiveness and efficiency of CAD teaching and strategies in the curriculum of architecture. The study also examined the need for a framework within which the creation of a module for applying CAL in CAD to support the curriculum of architecture can be structured and assessed. The main concern of the study was to explore the range and balance of computer assisted activities in the design studio, and the interpretation of the various roles of the CAD tutor and his/her involvement in delivering these activities. In delivering these activities two criteria, namely: teaching methods and CAD integration (which are interchangeable and yet play different roles), can have a distinct effect on the implementation of CAL in the design studio. The case study evaluated and investigated the CAL the AEC course as part of the 3rd year design studio at Mackintosh School of Architecture, to determine to what extent the AEC learning events were effective in advocating new strategies in CAD. The methods of this investigation consisted of classroom observations and administrating questionnaires. Variables such as the group and gender differences/participation, the tutor’s confidence, level of administration and strategies to help with technical problems and motivations, also the task-related activities, tangibility of the learning materials, and the minutes of lesson have been examined. The global rating of the CAL events in CAD lessons, the CAL organisation and sequence, the level of students’ confidence, the rate of students’ interest, the mode of classroom, the level of learner performance and the relationship between CAL and the overall curriculum have also been empirically examined and their interdependent relationships explored. The findings of this study may help in establishing future directions in adopting some form of effective CAL strategies in CAD. The study also serves as an evaluation tool for computing teaching in the design studio. Furthermore, the checklist used in this case study may also be used in evaluating the different courses in CAD in the curriculum of architectural schools.

source Architectural Information Management [19th eCAADe Conference Proceedings / ISBN 0-9523687-8-1] Helsinki (Finland) 29-31 August 2001, pp. 249-255
summary This paper reports on a contemporary and laborious ongoing experimental work initiated during the establishment of a new Virtual/Digital design studio “VDS” in Sept. 1999 by CAAD tutors at University of Petra “UOP”. The new VDS/DDS now works as an experimental laboratory to explore several solutions to problems of efficiency in design teaching as a new digital design studio paradigm, in tandem with CAD/Design staff, DS environment, materials and facilities. Two groups of graduating level students participated as volunteers in this experiment. The first group was comprised of three fifth-year architectural design students while the second group was comprised of two fourth-year interior design students. The media currently in use are ArchiCAD 6.5 as a design tool along with CorelDraw 9 as a presentational tool, running on Pentium III computers. The series of experiments evaluated the impression on architectural design studio tuition requirements arising from the changes brought about by the implementation of the new CAD pedagogical approach (VDS/DDS) at UOP. The findings echo several important key issues in tandem with CAAD, such as: the changes brought about by the new design strategies, adaptation in problem solving decision-making techniques, studio employment in terms of environment, means and methods. Other issues are VDS/DDS integration schemes carried out by both students and staff as one team in design studio practice on one hand and the curriculum on the other. Finally, the paper discusses the negative impact of conventional design studio hardliner teaching advocates and students alike whose outlook and impressions undermine and deplete effective CAAD integration and obstruct, in many instances, the improvement of such experiments in a VDS environment.

summary Recently digital-design techniques have influenced the way architects think and design. This extends to impact architectural edu- cation by drawing new boundary lines. Therefore, it is desirable for architectural educators and students to consider these lines and to know how to establish them within these technological trends. This will be through raising their knowledge and skills in three aspects, which are algorithms and geometry characteristics, authorship, and fabrication in digital architecture.

summary To understand the current architectural digital design techniques, architects and architecture educators and students need to know that these techniques are the new tool set. These techniques offer architects a new way of thinking and designing and enhance complexity. They will link architecture design with mathematics and computation, and they will generate and improve ideas. Giving that Saudi architectural education is still using traditional manual techniques and using technology only for drawing and montaging, this evokes the fact that there is a need to know and understand these techniques and their importance.

summary Our research aims to understand the mid-level patterns of work that recur across designers and tasks. Our users comprise active architects and civil engineers. The hypothesis is that making such patterns explicit will result in improved expert work practices, in better learning material and suggestions for improvements in parametric design. The literature shows that patterns express design work at a tactical level, above simple editing and below overall conception. We conducted a user experience study based on Bentley’s GenerativeComponents, in which geometry can be related, transformed, generated, and manipulated parametrically within a user-defined framework. After interviewing the system’s chief, we ran a participant-observer study in the January 2007 SmartGeometry workshop. We engaged designers through the role of tutor and simultaneously observed and discussed their design process. We found clear evidence of designers using patterns in the process and discerned several previously unknown patterns. In February at another 10-day workshop, we found more evidence supporting prior findings. The paper demonstrates that participant observation can be an efficient method of collecting patterns about designers’ work and introduces such new patterns. We believe these patterns may help designers work at more creative levels and may suggest new ideas of interest to CAD application developers.

summary Traditional construction site monitoring primarily relies on a human presence. Automated construction progress monitoring is expected to make this process much more efficient and precise. The planned state of construction (as-planned) must be validated by the actual state (as-built) during automated construction progress monitoring. This research uses an integrated application of high-resolution low-altitude UAV (Unmanned Aerial Vehicle) oblique photogrammetry and Building Information Modeling (BIM) technologies for construction site management. A case study was carried out for a renewable energy development program in the JiaDing District of Shanghai, China. A high-resolution 3D model of the construction site acquired by our multi-motor UAV provides data to illustrate the as-built state of the construction program. Comparison of the UAV-based 3D model (as-built) with the BIM-based 3D model (as-planned) for a specific chimney was used for dynamic construction site monitoring. Our results show 3D illustrations of construction progress. This research demonstrates that the BIM technology in conjunction with the use of UAV photogrammetry provides efficient and precise as-built data collection and illustration of construction progress.

summary Manga is a type of stylised bitonal drawings pleasing in terms of screen variety and tidy lines. In this paper, we present a method to draw architecture, spatial compositions and their details, including colours, textures, and tones, using manga drawing techniques. Given a colour image, such as photography, or drawing, our method finds the optimal solution for screening during the bi-tonal transformation, as well as a set of ideally abstracted line drawings. This offers a novel rendering appearance for the communication of architectural design. In our results we demonstrate successfully that our method generates manga-like drawings from an architectural image that preserve architectural key-elements, such as surface or material properties.

source ACADIA Workshop ‘85 [ACADIA Conference Proceedings] Tempe (Arizona / USA) 2-3 November 1985, pp. 129-141
summary Energy Graphics is a technique for determining the energy performance of buildings at the conceptual stage of the architectural design process. Unlike many energy analysis programs, which only produce results after ail of the building information has been supplied, Energy Graphics works with the designer in understanding how early decisions about building form and configuration affect energy use.

The Energy Graphics technique is currently being "computerized" on a Sun 2/120 graphics workstation, under a grant by the Inter-University Consortium for Educational Computing. The resulting software will be used in the architectural design curriculum so that students will be able to receive an immediate energy evaluation of their design explorations.

For use in the studios, the software must include a powerful graphics interface that allows students to "sketch" their design concepts interactively. The computer will then interpret these sketches as building information, organize them into an integrated database, perform the energy calculations, and inform the student of the results in a graphic format. One of the project's major goals is to provide this graphics interface in the same way that architects think about drawing, and not simply to imitate current computer "drafting" systems.

The goals of the project can only be met by developing the software on a powerful workstation system, which provides fast processing time, large memory, multitasking capabilities and high-resolution graphics. This progress report describes our efforts to date on the development of this important software.

summary This paper explores the process of digital materialization through robotic fabrication techniques by presenting three wooden projects. The analysis of the case studies is oriented to underline the impact that computation had on architectural construction due to its methodological and instrumental innovations over the last decades. The absorption of computing and digital fabrication logics within the discipline is explored from either an architectural point of view and from the improvements related to automation of the constructive process. On the one hand the case studies are caught because of the desire to expand material complexity and, on the other hand because of the integration with other technological systems. The narrative allows gathering pros and cons in three different investigative macro areas: material culture, methodological oversights, and operative setbacks coming from digital machine and communicational constraints. This analytical investigation helps the definition of a new pathway for future researches, looking forward the assimilation of digital materiality learning in building construction.

title New enchantments: design, hypermedia, and motivation
source SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 69-74
summary From the analogy between computer and theater, such as proposed by Brenda Laurel, this paper aims to introduce a discussion on the possibility of contemporary dramaturgies’ contributions to the project of hypermedia interfaces that are able to motivate the users action. Some of Bertolt Brecht’s concepts, although namely opposed to Aristotle´s poetics, are briefly introduced as they refer to the idea of commitment with audience motivation. This approach requires the presentation of some key issues regarding the idea of engaging human-computer experiences. These issues evolve from Laurel’s theory, published in the early 1990s and focussed in the computer as a medium for action representation, to contemporary concerns that start to address the urge for new study fields related to the design of human-computer activities.

source FUTURE CITIES [28th eCAADe Conference Proceedings / ISBN 978-0-9541183-9-6] ETH Zurich (Switzerland) 15-18 September 2010, pp.557-564
summary This paper highlights the use of ubiquitous technology to effectively enable location estimation in a system that promotes the display of surrounding information during a sightseeing cruise. The proposed system stands on the applicability of WiFi signal strength to grasp current location and on the use of web-tagged place information on the contents of riverfront places and its revival processes. The effectiveness of system in both technical and social aspects was verified promoting a river cruise in downtown Osaka in cooperation with volunteer citizens, experts and a cruise company. The accuracy provided by the WiFi location estimation presented some failures at certain points but was satisfactory enough to guarantee the display of nearby information at certain level. The proposed web navigation was testified positive by respondents, although additional adjustments of its design and improvements of the WiFi server were pointed out as necessary steps.

summary This article presents a case study on a vertical building envelope design considering Recife ?s climatic conditions. It consists of the utilization of parametric and algorithmic processes to distribute sun shading devices. The study uses computational tools such as Grasshopper and the DIVA for Grasshopper. The latter is a thermal energy simulation tool that uses the Energy Plus 7.0 and Daysim for calculations. The model uses incident solar radiation simulation on the envelope as basis for distribution of shading devices. The result is a parametric model that automatically responds to urban and climatic characteristics, through simulations integrated to the 3D model.

source First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 323-328
summary The “action” of design is an integration process, in which values, information of different kinds and data leads to a physical object of “design”. This integration process is non-linear and multiple objectives aimed, producing complex requirements to computer programs. RID systems intend to develop a new tool for the design process, using an evolving structure in the perspective to introduce basic levels of “self-awareness” in the design process to relate analogue and digital tools. This paper proposes an interpretation of the design process, a model for it and the first ideas for a possible new generation of “self awareness” design software.

summary This paper aims to highlight the educational potential of the association between the architectural typology of temporary pavilions and digital fabrication process for architecture and urban planning courses. The pavilion theme is being increasingly exploited in various universities in the world, in order to work new paradigms of computational algorithmic architecture and new construction process, through digital fabrication labs. In this sense, these exercises can become a privileged and highly effective learning tool, due the impact of the integrated experience between creating (design), construction (to build) and experience (to appropriate the spaces).

title Conservation of Architectural Heritage:The Role of Digital Documentation Tools:The Need for Appropriate Teaching Material
source International Journal of Architectural Computing vol. 5 - no. 2, pp. 240-253
summary Currently, a wide range of digital sensors for capturing our architectural heritage are available. They offer the opportunity to acquire large sets of information in a relatively short time. These sensors include digital photography (photogrammetry-scaled rectified photography), total stations, laser scanners, high-resolution panoramic devices, etc. A lot of effort has been put in the application of these tools in the field of conservation, however a significant gap exists between the information needed by professionals working in the field of conservation and manufacturers claims of these new technologies. The realistic application of these tools for heritage documentation products needs to be addressed. Offering the architectural heritage community didactic material on how and when to use these tools appropriately can address this gap. This paper presents the teaching material being prepared under the CIPA/RecorDIM initiative to overcome these issues and begins to address the need for a common framework of standards in heritage documentation.

summary The dialogue between people from different social groups (class, gender, race or sexual orientation) could help develop a sense of empathy, reduce discrimination and catalyze socio-spatial transformations. However, the space usually acts segregating these groups or suggesting how they should behave. Architects, usually unconsciously, reinforce this through their practice, labeling otherwise abstract spaces to determine users behaviour and so reproducing social norms. The aim of this article is to investigate how space shapes human interaction and to introduce Trambolho, an interface that is not attached to any previous meaning, which people can use to negotiate and build a shared space.

source SIGraDi 2011 [Proceedings of the 15th Iberoamerican Congress of Digital Graphics] Argentina - Santa Fe 16-18 November 2011, pp. 118-122
summary The ongoing research is focused on the development of a low-cost solar tracking system to improve domestic fixed PV installations which performance is dramatically diminished due to the absence of reorientation mechanisms to maximize solar energy capture. A straightforward way to reduce fabrication and maintenance costs of a domestic solar tracking system is to avoid the use of photoresistors. Most solar trackers use photoresistors to reorient their PV panels. However, the daily and seasonal solar path is well known and its variation is negligible when comparing photoresistorbased and preprogrammed reorientation against the amount of solar energy that is captured.

summary We present a novel CAD/CAM apparatus and method for single-pass cutting of double-curved expanded polystyrene formworks. A rationalization approach was implemented using generic solvers in a popular free visual programming environment integrated into a well-known commercial CAD software, which allows finding elastica curve sections for processing double-curved NURBS surfaces. This procedure allows us to convert bending curves geometry into G-code coordinates for numerically controlling a flexible cutting hot-blade. A prototype 7-axis machine was experimentally validated in a series of cutting processes of EPS formworks to build a double-curved concrete pony wall.

summary This paper aims to study the potential impact of Virtual, Augmented and Mixed Realities (VAM) technologies on the built environment and to understand how immersive environments can be used to enhance the human experience within the built environment. In order to investigate and test how these technologies may improve our experience of the city, an augmented reality app is being developed in partnership with Victoria University of Wellington, the Wellington City Council and NEC, New Zealand. The research aims to explore ways in which VAM helps users in exploring cities. The philosophical driver of this project aims to focus on supporting the experience of moving between two points on a map rather than achieving the shortest route to a destination. Once developed, the project proposes the CityAR app which is to be distributed to the general public in order for them to test its functionality and in return, provide user feedback.

Glocalization. The Common Good. Buzz phrases like "global village" or "global information society" are misleading. The concept of "global" is not itself global, in other words globalization is not "universal", it does not affect everybody in the same way. Exactly like the very concept of "universality" is not itself "universal". I am referring here to some Asian voices raising concerns about the "occidental" flavour of the "Universal Declaration of Human Rights" and supporting the idea that "Asian values" were not taken properly into account and might even be in contradiction with it (for instance the confucean predominence of the Society over the rights of the Person).

summary In recent years, citizen participation has begun to progress in administration plan development. However, preparations for argument are not enough so that the citizen who is non-expert participates to administration plan development. In addition, arguments among experts are not understandable to citizens. In sum, experts cannot explain to citizens plainly. They often show only a result and a conclusion of their argument. Therefore the result of their argument cannot obtain sympathy of citizens. As a result the effectiveness of the administration plan has been deteriorated. For citizen participation, it is necessary to represent the process of an argument by arranging the information and ranking them for an argument. The purpose of this research is to adopt the knowledge management in planning a city master plan and to develop the systematic tool for the consensus decision-making in planning a city master plan. This tool supports a resident group for making a city master plan.

summary CAM systems traduce design information from CAD systems in to different manufacturing routines in order to produce NC code for CNC machinery. The output from the CAM software is usually a simple text file of G and M code, usually containing thousand of lines of code. Later this code is transferred to a machine tool using a direct numerical control (DNC) program. This translation process becomes extremely important in developing a digital design and fabrication approach. Consequently the aim in this research is; to investigate CAD-CAM workflow; to analyze final product deviation from design intent; and to determine where in the workflow, and how design strategies and design decisions correlates to manufacturing results.

summary Urban plan and architecture require the use of VR systems. We adapted the buildings into a VR system, and then performed a virtual realization in the world’s largest dome at Matsushita Electric Works, Ltd. Walking or flying through life-size space was enabled. We viewed the planned future scenes that featured real size, space composition, and a simulated environment. The construction, the materials and colors of the building were examined. In addition, VR system on PC was applied to city planning and architectural design and a number of novel functions were added to the VR system by plug-in, which assisted and facilitated the design process. The stereoscopic thinking mode in 3-D space can inspire and comprehend more directly the ideas of design, and confirm the intended effects. We accordingly carried out a further study on users operating the VR system to investigate their responses of “like” or “dislike” towards the real time adjustments of design effect at identical viewpoints. Fractals analysis was conducted to demonstrate physically the influence of real time 3-dimentional design and presentation on the psychological trends of subjective judgment. Our findings pave the way for future research on monitoring psychological impacts on observers of VR system during design process.

summary The aim of this paper is to understand the outcomes of parametric methods in beginning design projects and their impact on rethinking digital technology in current design education. In order to realize comprehensive results, in this paper i) conceptual and formative projects are presented to describe specifications of a parametric design at OSU School of Architecture; ii) for OSU SOA, we plot pedagogical objectives and evaluate how we have interpreted and applied novel digital technology into the design process; and iii) Cultivate parametric design as systemic and organizational design. Along with unit-based, component design, expand the use of digital tools to become the discipline and domain of the creative culture. How digital tools are integrated into early design education through a collaborative studio project will be the focus of the study. Through the experimental exercises, we can begin to explore how the digital process can be integrated at a fundamental level.

summary Utilization of computer-aided architectural design CAAD in architectural design studio has its problems. Recently, CAAD has been over used within education, , and applied, presumably, more efficiently in professional contexts.. Noticeably, time available for the application of CAAD in architectural firms outweights that of academy. Consequently, it has to be utilized effectively and efficiently in the design studio. The current study proposes and discusses techniques to expand and consolidate CAAD utilization in the design studio by analysing stages of work of design professionals, as well as the utilization of CAAD in architectural firms, in the first phase. The second phase looks at the stages of work in the design studio academically. Later, we conduct a survey and categorization of the Egyptian schools of architecture, to identify the mechanisms of their CAAD applications. We aim to improve the synergies between academia and professional practice and, in this respect, we hold a comparison between the professional context and the academic context with emphasis on the pedagogical aspects of architecture in design studio. The third part makes proposals to bridge the gap between the professional practices in the applications of CAAD and academic practices via enhancement of architectural technology-based learning milieu. The proposed techniques are applied and examined in the design studio. They aim to establish the parallelism between academic objectives and professional and technological objectives.

title A COMPUTATIONAL SYSTEM FOR ENRICHING DISCOVERY IN ARCHITECTURAL DESIGN
source CAADRIA 2006 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Research in Asia] Kumamoto (Japan) March 30th - April 2nd 2006, 169-177
summary This paper presents a computational system for enriching design discovery in the external 2D representation of architectural plans. Enriching discovery is achieved through an interpretative search process that involves emergent findings. The developed computational system employs a twofold discovery process, generative phase and an interpretative or explorative phase. In the generation phase the system allows designers to depict an initial building design in the form of 2D plans as a set of lines. The system recognizes possible components of the initial design by generating different forms of bounded shapes that are both explicit and implicit using the Hamiltonian circuit approach. In the interpretation phase the discovery process using the quest mechanism is invoked by selecting a geometrical semantic identified in the recognized shapes to generate possible alternative interpretations of the complete representation of initial design. This plays an important role in enriching discovery in the architectural design of buildings and provides a set of new moves and directions for the designer to pursue.

title Spatial Forms Generated by Music – The Case Study
source International Conference on Generative Art
summary This paper resulted from the first stage of an ongoing collaborative research between a multi-senses artist (R. T.) from New Zealand and an architect interested in generic architecture (M. D.) from Yugoslavia. The research examines potential relations between music and architecture and explores the ways music could be a source for generation of spatial forms, and vice versa, whether architecture might generate music. In the first stage of the research two different existing generic principles were combined. The graphical interpretation of the music served as a pattern for creating the spatial forms. In this experiment the Brahms’s Hungarian Dance No1 has been used as an initial generator. The music is transformed into the sequence of linear drawings. Every single drawing potentially defines a spatial composition, while each single line represents an axis of the future spatial form. Together with geometric definitions there are some ambient values, like color, transparency and many others, that can be determined by music. After an overview of results, paper concludes with perspectives for future research that will include time as an additional dimension towards generating dynamic spatial concepts based on music.

summary To deviate from conventional metallic structural elements is not an easy achievement, especially if free forms with curved surfaces are wanted. One approach that makes sinuous volumetric metallic shapes accessible is curved folded sheet metal.The aim of the current application is to create a reinterpretation of the classical column, an architectural element which is both decorative and structural. This is achieved through curved crease folding of steel sheet metal. To aid the form-finding process, a virtual simulation of the bending process is done using computational means.

title The Computer Methods of Construction Spiral Structures
source Proceedings of the 8th European Architectural Endoscopy Association Conference
summary The object of our research is geometric characteristics of spiral structures which are widely spread in nature (cones, sunflower beds…). It is a well-known fact that there is a proportional intercommunication according to the “golden section”. The correlation of the quantity of “right” and “left” spirals ties to have an irrational coefficient of “golden section” through the correlation numbers of 1,618… from Fibbonacci series ( 5/3, 8/5, 13/8, 21/13, 34/21, 55/34 …). When the proportion of “golden section” was found in the natural objects since the middle of the 19-th century (A.Zeizing), there began to appear a lot of hypotheses about some special aesthetic and technological characteristics of this proportion. The proportion of “golden section” became the most important architectural instrument in the first half of the 20-th century. This instrument made it possible to design beautiful and comfortable buildings (Le Corbusier). We tried to find a geometric way of building spiral structures which would be similar to natural ones. We solved this problem with the help of the developed algorythm the geometric characteristics of the cells of which spiral structures are built were investigated. It was found out that the cells of “golden” spiral structures don't have any special characteristics if compare with the cells of other spiral structures. During our work we found some spiral structures which have optimal geometric characteristics. These structures let's call them radial-hexagonal, have maximal area of a cell, though they have minimum perimeter. We also defined the main difference in the growing strategy of animate and inanimate structures. Inanimate structures grow by means of addition external elements. Animate structures grow by means of constant pushing of new elements which appear in the centre towards periphery. The optimal filling of the plane in the process of such growing is possible only by “golden section” of “right” and “left” spirals.

summary The creation of building components that can be seen as sustainable, inexpensive, stronger, recyclable, customizable and perhaps even reparable to the environment is an urgent, and critical focus of architectural research. In the U.S. alone, the construction industry produced 143.5 million tons of building-related construction and demolition debris in 2008, and buildings, in their consumption of energy produce more greenhouse gasses than automobiles or industry.Because the inherent nature of 3D printing opens new possibilities for shaping materials, the process will reshape the way we think about architectural building components. Digital materiality, a term coined by Italian and Swiss architects Fabio Gramazio and Matthias Kohler, describes materiality increasingly enriched with digital characteristics where data, material, programming and construction are interwoven (Gramazio and Kohler, 2008). The research aspires towards this classification through the use of parametric modeling tools, analytic software and quantitative and qualitative analysis. Rapid prototyping, which is the automatic construction of physical objects using additive manufacturing technology, typically employs materials intended for the immediate analysis of form, scale, and tactility. Rarely do the materials used in this process have any long-term value, nor does the process - except in rare cases with expensive metal prototyping - have the ability to create actual and sustainable working products. This research intends to alter this state of affairs by developing methods for 3D printing using concrete for the production of long-lasting performance-based components.

summary This paper presents an experimental study on strategies of utilizing wind as an architectural element, proposing the reconfiguration and projection of wind patterns to produce vaults of wind as regions of shelter in the outdoor environment. It shows an aerodynamic analysis and exploration of barriers, deflectors and porous screens in an existing urban wind canyon for a hypothetical urban shelter in a tram stop area. Computational Fluid Dynamics (CFD) software and physical tests in a wind tunnel using microelectronic hot-wire anemometry are the methods utilised. The experiments involve a comparison between screens with impermeable surfaces and porous membranes and their ability to project wind as architecture. The experiments showed that the use of porous membranes improves the mitigation level of wind speed and turbulence intensity in the wind vaults regions.

source International Journal of Architectural Computing vol. 8 - no. 3, pp. 279-300
summary This paper assumes the façade as an innovative element of interaction between the inside and the outside: the architectural skin. As in nature, one of its most significant functions is the energy exchange with the environment. Similarly, efficiency increases by passive and active responses to climate conditions and site orientation. This research explores the potential of parametric techniques, programming and digital manufacturing, to design and build a Bioclimatic Responsive Skin (BRS). Firstly, we designed a bio-component applicable to any surface due to its parametric nature. Secondly, we fabricated two non-reactive working prototypes to study the manufacturing and construction details. Thirdly, we integrated the physical and the digital interfaces by using Generative Components™, Arduino, and Ubimash to generate a kinetic responsive model. This prototype was presented at SmartGeometry Workshop and Conference 2010. Finally, Lem3a architecture used this BRS in a real design project for a Sustainable house in New Hope, PA.

summary This paper presents a research on the techniques of traditional Malay ‘shadow play’ used in developing new concepts for representing interactive media. This funded research by the Selangor State Library is developed based on a book collection on the aural history of Sabak Bernam, one of the counties in Selangor located in the West Peninsular of Malaysia. It considers the domain of conceptual spaces within the shadow play setting and spaces by addressing the typology of the design. Representation of different character and environmental styles related to the Malay cultures were developed as multimedia content involving more than fifty local villages. It suggests form for background consideration of possible metaphors, the space arrangement of the elementary and actors, spatial relationships, audiences and the techniques of puppetry in the design for multimedia environments.

title Virtual environments in architecture and planning design: 4 possible approaches
source International Journal of Design Computing
summary Advancements in information retrieval (IR), local and wide area networks (LAN, WAN) and the Internet, human-computer interaction (HCI), and virtual reality (VR) technologies have enabled the emergence and availability of affordable real-time computer data visualisation and manipulation systems that can be deployed and interfaced to most Computer Aided Design (CAD) software systems. However, the rapid advancement and adoption of information visualisation in different areas is currently challenging VR system designers to formulate and deploy strategies and tools to effectively visualise, navigate and effectively communicate various types of information within a virtual environment (VE). A further problem relates to the fact that even within a single area or application the requirements are still diverse to the extent that different approaches and technologies still need to be employed before a satisfactory solution is reached.

This paper presents four possible approaches in identifying and designing effective VR systems for architecture and planning design to allow the user to effectively communicate and share their experiences and ideas in a collaborative manner. It is also proposed that VEs should look beyond plain representations and reproductions of the real world environments that they portray and bear higher interpretation and expression values. The value of eliciting structuring and interfacing information and knowledge to a VE is also highlighted, as is the need for efficient database systems and CAD systems capable of exchanging information and data with VEs. Current efforts in prolonging the lifetime of VEs are being examined through four case studies that highlight the ever-escalating requirements that currently face VR researchers.

title Improving spatial ability using a Web-based Virtual Environment (WbVE)
source Automation in Construction
summary Spatial ability is one of the cognitive means used in problem solving activities particularly when manipulating and processing visuo-spatial information. With the increasing use of network communication, conventional teaching and learning has shifted towards the development of network environments, online learning, real-time interaction and high quality multi-user collaboration. This paper presents our experiment using a Web-based Virtual Environment (WbVE) that has improved a group of pre-service teachers' spatial ability understanding for teaching Engineering Drawing for secondary school subjects. The experiment is carried out in Universiti Pendidikan Sultan Idris (UPSI) comprising of 98 pre-service teachers taking the Computer Aided-Design (CAD) course. Selected subjects were pre-tested at the beginning of the semester with spatial tests focusing on mental rotation and spatial visualization to provide the baseline measurement. A desktop WbVE, which was employed and tested in the CAD laboratories to improve their spatial ability for five weeks of instructional treatment, will be demonstrated. Post-testing of spatial tests revealed significantly the overall spatial ability improvements as measured by the test scores. This paper concludes with a discussion on the impact of WbVE spatial learning that will be used as a precedent in the development of the VE teaching and learning prototypes for secondary school in Malaysia.

source Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 87-94
summary This paper reviews several theoretical frameworks of visual analysis used in computer-based Visual Impact Assessment (VIA) for design decisions in architecture, urban landscape and urban planning. The discussion will focus on the underlying issues of preferences and predictions between designer and lay-public, methodologies of visual analysis, and computing media technologies due to fact that these components primarily contribute towards the result of VIA. Two different sets of visual analysis (i.e. designer’s and layman’s points of view) are presented based on Sanoff’s (1991) arguments that lay-public preferences are always become a second opinion compared to the judgments by designers. These theories will then be developed and used in the VIA experiments to understand the impact of the visuals in different media for viewers’ understanding. This paper concludes with a discussion and suggestion of analysis framework to be used for the visual experiments.

source Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 301-304
summary This research presents our progress of the second phase of City Administration System (CAS) (Rafi and Fazidin, 2001). It covers the terrain generation of Kuala Lumpur’s Central Business District about 30km x 30km at 1 meter resolution using the latest stereoscopic satellite data and survey data from Mapping Department of Malaysia’s Ministry of Science, Technology and Environment. CAS will be designed to have three main functions, namely: Flood Crisis Management (FCM), Architectural and Town Planning Management, and City Services and Administration. At a 1meter resolution, CAS will be able to predict, manage and visualise flash and major floods within the city with a very high degree of accuracy. It has been identified for CAS that there is a need to share information through collaborative environment in a more centralised manner that allows collective decisions, facilitates continuous updates, communicates effectively and permits the sharing of experiences and ideas.

title The relationship of spatial experience, previous mathematics achievement and gender with perceived ability in learning engineering drawing
source Journal of Technology Education, 18(2), 52-66.
summary This study examined the relationships among three factors namely spatial experience, previous mathematics achievement and gender, with students’ perceived ability to learn Engineering Drawing at the foundation year. A correlational and regressional descriptive design was utilized involving 224 students of secondary schools. Two survey instruments comprising Spatial Experience Questionnaire (SEQ) and Student Questionnaire (SQ) were administered to elicit participants’ demographics and their perceived ability to learn the course. Correlational analysis found a significant correlation between perceived ability and spatial experience. Perceived ability was slightly correlated with previous mathematics achievement and gender. Regressional analysis attested spatial experience as the only variable to have a strong predictive power to account for variation in perceived ability.

title On Improving Spatial ability through computer-mediated engineering drawing instruction
source Journal of Educational Technology and Society 9 (3), 149-159.
summary This study investigates the effectiveness of computer-mediated Engineering Drawing instruction in improving spatial ability namely spatial visualisation and mental rotation. A multi factorial quasi experimental design study was employed involving a cohort of 138, 20 year old average undergraduates. Three interventional treatments were administered, namely Interactive Engineering Drawing Trainer (EDwgT), conventional instruction using printed materials enhanced with digital video clips, and conventional instruction using printed materials only. Using an experimental 3 x 2 x 2 factorial design, the research has found statistical significant improvements in spatial visualisation tasks. There appears to be no improvement in reaction times for Mental Rotation. The authors also have investigated the gender differences and the influence of prior experience of spatial ability.

title High dynamic range images: Evolution, applications and suggested processes
source Proceedings of the 11th International Conference on Information Visualization (IV07), ETH Zurich, Switzerland, 4-6 July, 877-882.
summary Three dimensional (3D) and Computer Graphics (CG) industries nowadays require ‘instant’ realism and extreme special effects while imposing the balance in cost, time and solution acceptance standard. It has been known that realistic rendering is time consuming, difficult to use, complex, expensive and often produces insufficient digital output to predict particularly in the early visualization process. This paper focuses on one of the emerging technologies, High Dynamic Range Image (HDRI) and how it can be developed in achieving effective solution, while maintaining ‘realism’ or required result based on a specific application. We firstly introduce the overall HDRI processes before continue to present a framework of captured Low Density Range Image (LDRI) source sequence effectively in HDRI environment. This paper concludes with discussions and lists the application of HDRI.

title Design creativity in emerging technologies
source In Von, H., Stocker, G. and Schopf, C. (Eds.), Takeover: Who’s doing art of tomorrow (pp. 41-54), New York: SpringerWein.
summary Human creativity works best when there are constraints – pressures to react to, to shape, to suggest. People are generally not very good at making it all up from scratch (Laurel, 1991). Emerging technology particularly virtual reality (VR) Multimedia and Internet is yet to be fully discovered as it allows unprecedented creative talent, ability, skill set, creative thinking, representation, exploration, observation and reference. In an effort to deliver interactive content, designers tend to freely borrow from different fields such as advertising, medicine, game, fine art, commerce, entertainment, edutainment, film-making and architecture (Rafi, Kamarulzaman, Fauzan and Karboulonis, 2000). As a result, content becomes a base that developers transfer the technique of conventional medium design media to the computer. What developers (e.g. artist and technologist) often miss is that to develop the emerging technology content based on the nature of the medium. In this context, the user is the one that will be the best judge to value the effectiveness of the content.

The paper will introduce Global Information Infrastructure (GII) that is currently being developed in the Asian region and discuss its impact on the Information Age society. It will further highlight the ‘natural’ value and characteristics of the emerging technologies in particular Virtual Reality (VR), Multimedia and Internet as a guidance to design an effective, rich and innovative content development. This paper also argues that content designers of the future must not only be both artist and technologist, but artist and technologist that are aware of the re-convergence of art and science and context in which content is being developed. Some of our exploration at the Faculty of Creative Multimedia, Multimedia University will also be demonstrated. It is hoped that this will be the evidence to guide future ‘techno-creative designers’.

title Design computing: A new challenge for creative synergy
source In Saito, N. (Ed.), Creative digital media: Its impact on the new century (pp. 132-136), Japan: Keio University Press
summary As content becomes increasingly significant in giving ‘face’ to information technology (IT), the need to train and produce content designers has also become more and more important. The development of powerful computer technologies and the complexity of design have demanded designers to re-examine the design process and consider the adaptation of tools that will provide for creativity, improve the overall design process and, at the same time, reveal new insights (Rafi and Karboulonis, 2000). This paper gives an overview of the relationship between art and science through the ages, and discusses their relatively recent re-convergence. This text further argues that a re-convergence between art and science is currently occurring, highlighting the need to accelerate the process. It is suggested that re-convergence is a result of new technologies being researched, namely related to effective visualisation and communication of ideas and concepts, subsequently adopted by practitioners. Such elements, with tools that offer increased power and new abilities, are widely found today in the multimedia and the Virtual Environment (VE) as scientists and designers venture into each other’s domain. This paper also argues that content designers of the future must not only be both artist and technologist, but artist and technologist that are aware of the context in which content is being developed. The presentation will be a showcase of our exploration at the Faculty of Creative Multimedia, Multimedia University for the last 4 years, in integrating design and computer skills – the synergy that we called DESIGN COMPUTING.

summary This paper reports on Malaysian’s experience in suggesting and maintaining two cybercities (i.e. Putrajaya and Cyberjaya) or Intelligent Cities. The advantage of the convergence of technology has been implemented at national level as a means to increase human participation and to prosper in the Digital Age, in their daily life, business, education and other urban activities. It starts with an overview of ‘High-tech Corridors’ in Asia countries namely Philippines, Thailand, South Korea, and Singapore and its impact to these countries. The foundation of this study presents the criteria of Intelligent Community (IC) that makes a city intelligent without excluding the value of the citizen quality of life, culture and religion by associating with the Information and Communications Technology (ICT). We introduce and present www.i-Putra.com.my, a portal of digital soft city of Malaysia’s new administrative Capital, Putrajaya. This national project is funded by Putrajaya Holdings Sdn. Bhd. Malaysia and was originally developed by the Multimedia University before finally executed by I-Design Sdn. Bhd. It is designed to be an interactive channel to provide the services for different level of target audiences of the civic and urban activities. The guiding principle for i-Putra.com.my portal is content, context, community and commerce in which they will be integrated with the city information such as residential, commercial, service and public areas. It is hoped that this paper gives an example of good intelligent city concepts through a clear vision and planning, effective management, implementation and sustainable approach.

summary This paper explains the results of a collaborative research project between Multimedia University (Malaysia) and Innotive Corporation (Korea) to manage, design a multimedia archiving system and visualising knowledge for the students or the users in the Faculty of Creative Multimedia, Multimedia University. This research introduces InnotiveBrowser technology, a high performance multimedia display software that enhances the ability of user to search and discover digital content. The unique result of this method is that the images to be viewed are not limited to available RAM, instead the content utilises the available storage directly from the disk (hard drives). In other words, the larger the size of the hard disk, the greater the number of content information can be stored and displayed. This system is employed with Virtual Reality (VR) techniques particularly imparting viewing technology (pixel-ondemand) and navigation strategy to increase the viewing speed of multimedia information in real-time over the Internet, broadband and even via PDA platforms. This research hopes to set the benchmark for multimedia archiving system that can be applied in other CAD, CAAD or most of the design or production-based teaching and learning environment. The early findings of this research have been patented and this paper will demonstrate the research ideas and explain how we implement and customise the technology and content development in the Faculty of Creative Multimedia, Multimedia University.

title Creative Multimedia: The Commodity of the 21st Century
source International Conference on Generative Art
summary The Digital Revolution has turned individuals, institutions, and businesses into a new form of collective wealth and prosperity. This revolution has effected a creativity burst that goes far beyond an increase in the number of those involved in design tasks and challenges, in both professional and amateur settings. The Internet in particular are not only distributing media but most importantly it is a reference platform in which ideas, talents and capabilities emerge and are refined, enhanced and perfected through the inspiring interplay of collaboration and competition. This paper briefly examines the relationship between art and science through the ages, discusses their recent re-convergence, and examines their current relationship via real world applications and productions. The study of such productions, their successes and the impact they have had in the marketplace based on designs and aesthetics instead of advanced technology appear to support the argument. It also highlights the need for accelerating this process and suggests that the re-convergence is a result of new technologies adopted by practitioners that include the effective visualisation and communication of ideas and concepts. These elements are widely found today in multimedia, which offers increased power and new abilities to both scientists and designers. This paper also highlights the need for the employment of emerging computer-based interactive technologies which will enhance the design process, better decision-making, increase the quality of communication and collaboration, lessen the errors and reduce the design cycles. A Multimedia Palette is proposed as a design platform to expose one's imagination, creative and innovative ideas, and provide a richer and more creative multimedia content design and development. Following encouraging first round results, an expanded version of the suggested platform has been experimented in the Faculty of Creative Multimedia, Multimedia University for the last 5 years, in integrating design and computer skills in the teaching and learning projects.

summary This paper presents our experiment and development of i.Putra.com - a digital soft city of Malaysia's new administrative Capital Putrajaya. This project is funded by Putrajaya Holdings Sdn. Bhd. Malaysia and was originally developed by the Multimedia University before finally executed by I-Design Sdn. Bhd. It is designed to be an interactive channel for the civic and urban activities that parallel, enhance, compliment, and sometimes 'compete' with physical Putrajaya. Putrajaya's goal is to be the administrative capital for the governance of cyber communities where digital bits rather than physical assets are the primary scarce resource (Putrajaya Holdings, 2002). The guiding principle for i.Putra.com is content, context, community and commerce in which they will be integrated with the city information such as residential, commercial, service and public areas. As the city is being built, i.Putra.com will expand to provide an interactive channel for those who live in, work in, or visit Putrajaya.

summary This paper suggests a method known as High Dynamic Range Image (HDRI) to pre-visualise architectural elements in three-dimensional (3D) environment used by Computer Graphic Imaging (CGI) film-makers to integrate 3D models and characters into live action background (special effect). This Intensification Research Priority Area (IRPA) grant project was developed to suggest ways to achieve effective rendering solution and composition of the final output. It will focus on experimental modelling of local cultural elements that provides solutions for radiosity-type effects and dirt shadings. A set of data from an established site (i.e. environment) was captured and represented in High Dynamic Range (HDR) file. This data is integrated with architectural elements (e.g. 3D objects) and then pre-rendered to get the 3D visualisation of the actual environment. Several different exposures were also captured and tested to establish the correct rendering and lighting condition. This earlier result shows that HDRI method provides accurate visualisation and drastically reduces the rendering time without compromising the data (images) with accurate lighting. This paper will demonstrate the process of HDRI, compare the visual impact with ‘radiosity’ technique and other related rendering solutions and present the results, which are useful for architectural animation, simulation and other modelling developments.

summary This paper presents the i-putra business channel, a portal that has been completed with a comprehensive database of information relating to commercial and residential properties, and other on-going development components of Putrajaya, one of Malaysia’s intelligent cities. Designers were provided with multimedia-rich information of spaces before making a selection through the Interactive Land Use Database System (ILUDS) which hosted more than 67,000 units of residential and commercial areas in Putrajaya. The database was developed based on category searching features that aimed to be the one-stop brief explanatory system on the Internet. ILUDS depicts an innovative idea for city and urban development to prepare information and virtual interactivities for a better usage in a ‘soft city’ design. The system has the underlying structure that allows for partitioning and ease of handling within which the data can be structured under a graphical interface that facilitates editing, manipulation, attribution and updating. This attribute of city information and associate data offers users a different level of interactivity and provides effective use on architectural and city information.

source CAADRIA 2008 [Proceedings of the 13th International Conference on Computer Aided Architectural Design Research in Asia] Chiang Mai (Thailand) 9-12 April 2008, pp. 445-451
summary This paper presents our attempts on virtual reality curriculum development for the past four years as one of the multimedia-based degrees. It will give an overview, goals and outcomes of the virtual reality (VR) curriculum with varieties of virtual reality systems, interactions and design theories used at different level of studies. It also highlights issues related to designing virtual spaces and the approach used to suggest a good storytelling. This paper will also explore, report and demonstrate the use of non-immersive virtual reality system based on a study in a problem-based learning environment of a virtual reality majoring. Following early encouraging first round results this paper concludes that experiential design could be one of the effective approaches for a problem-based learning and richer content creation of virtual environment (VE) design. It also suggests that the presence of motions, different field of views, interactivities and stereoscopic visions are attributes of three-dimensional (3D) visualization that contribute to better understanding and designing virtual environments.

title Simulation of architectural lighting in a virtual environment - A case study on real and fake High Dynamic Range Images (HDRI)
source Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 566-572
summary The early findings of this research were presented in eCAADe 2005 International Conference, Lisbon primarily to highlight the concept of High Dynamic Range Images (HDRI) when representing architectural spaces in the form of still images. An experiment had been carried out to compare the results between HDRI rendering and ‘conventional’ lighting simulation algorithms namely ray tracing and radiosity. The results were based on static and using the same exposure factors, when capturing HDRI. This project, funded by Intensification Research Priority Area (IRPA) grant continues to present and report HDRI results in a simulation environment. In this paper, we first briefly explain on the concept of real and fake HDRI. Then a comparison experiment is conducted to compare these two methods and discuss the impact and effectiveness of the illumination computation in architectural simulation environment. In order to carry out the experiment, a few models of the architectural scenes were developed. These models were then textured with real photos and manipulated with ‘shaders’, and further rendered using fake and real HDRI techniques. As for the fake HDRI, two methods were developed. The first was using an image as the ambient map and different exposures were created by increasing the value of Hue, V of HSV and saturation. The second involved a series of digital photos with the selection of the brightest and darkest area using Adobe Photoshop to establish the scale of luminosity. A few camera movements were triggered and position for ‘real-time’ rendering simulation. The result of the experiment has shown a significant improvement on the rendering time and quality of the rendering. Finally this paper suggests the selection criteria for choosing real and fake HDRI, and how each technique can be best utilized for architectural representations in a simulation environment.

summary This paper discusses the visualization tools and methods used to examine human perception in Visual Impact Assessment (VIA). One of the key conservation areas in Kuala Lumpur was selected in the study to measure the impact of different types of visualization tools. This paper recommends that human perception contributes towards the improvements of the visualization tools for VIA. The study found out that the common visualization tools used were not the most preferable tools among respondents. On the contrary most respondent preferred interactive visualization that offered more visual possibilities leading to a better understanding of landscape design. Apart from this, the study identified that the visual perception between the respondents who have different formal education background have similar concerns on the visualization tools tested to them.

It then continues with the fundamentals of virtual heritage (VH) metadata structure adopted from the UNESCO guidelines. The key highlights to the content of e-Warisan SENIBINA will be demonstrated via techniques to reconstruct heritage buildings towards a collaborative architectural virtual heritage experience as closely to originally design features. The virtual reconstruction will be based on the techniques suggested by the research team tested earlier in a smaller scale of advanced lighting technique for virtual heritage representations. This research will suggest (1) content preparation for creating collaborative architectural heritage, (2) effective low-polygon modelling solutions that incorporate global illumination (GI) lighting for real-time simulation and (3) texturing techniques to accommodate reasonable detailing and give the essence of the VH.

title Interpreting digital heritage: considering the end-user’s perspective
source Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 93-102
summary Present virtual heritage projects are mostly focused either on ‘process’ or ‘product’ but rarely consider ‘user’ (end user’s perception of the content) with project contents predominantly developed with an ‘ocular-centric’ tendency. There is no significant interpretation method or principles for interpreting digital heritage unlike other disciplines such as archaeology. This paper argues that, for better interpretation and experience of a digital heritage site, a comprehensive interpretation method is required, which should address multicultural background of end-users and overcome the linearity and subjectiveness in content creation. This paper also argues that instead of pre-determined instructional sequences or descriptive interpretation, the interaction setting can be participatory and contributive, where the visitor and environment may interplay mutually with each other. As a methodology, ‘Interpretation’ is first conceptualized by assimilating definitions from heritage scholars and organizations. Notions of interpretation-practice and level of interaction were identified from reviewing some online digital heritage projects. By identifying weaknesses, this paper finally proposes a few suggestions for overcoming and possibly developing a comprehensive interpretation method for future digital heritage projects.

There is no significant interpretation method or principle for interpreting digital heritage like other disciplines such as archaeology. This paper argues that, for better interpretation and experience of a digital heritage site, a comprehensive interpretation method is required, which should address end-users with various background, overcome the linearity in narrative level and subjectiveness in content creation. This paper also argues that instead of predetermined instructional sequences or descriptive interpretation, the interaction setting can be participatory and contributive, where the end-users and environment may engage in ‘dialogic-interaction’. In terms of methodology, ‘Interpretation’ is first conceptualized by assimilating definitions from various heritage scholars and interpretation organizations. Notions of interpretation-practice and level of interaction are identified from reviewing some online digital heritage projects. By identifying weaknesses, this paper finally proposes a conceptual model for developing a comprehensive interpretation method for future digital heritage projects.

title A Comparative Study of Digital and Traditional Tools for Participative Design
source Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary Computer tools have been used by experts for a wide range of activities including design and planning, historical conservation, urban management, education, and marketing and promotion. However, the difficulty of using these tools has meant that they have only been used by experts and their benefits have not been available to the public when engaged in participative design exercises. This paper reviews the extent of computer tool usage within urban design and goes on to propose a new way of utilizing digital tools in order to involve non-experts. The work that is presented here takes the form of an experiment which compares the traditional participative design approach with one that employs a three-dimensional digital approach. The setting for the experiment is based on the design of student housing on the University of Bath campus in the United Kingdom. Findings from the experiment demonstrate that the digital toolkit that is proposed has considerable potential to aid the process of participatory design.

title The Realities of Introducing IT/CAD in Architectural and Interior Design Education: A Case Study at the Polytechnic of North London
source CAAD: Education - Research and Practice [eCAADe Conference Proceedings / ISBN 87-982875-2-4] Aarhus (Denmark) 21-23 September 1989, pp. 4.1.1.-4.1.9
summary This paper is an attempt to illustrate the realities of introducing Information Technology at a school of Architecture and Interior Design. The department, under the auspicies of the Polytechnic of North London, comprises of 520 full/part time students working towards various professional and postgraduate degrees and diplomas in Architecture and Interior Design. For the last 18 months, the department has undertaken a rapid IT/CAD implementation programme. This has involved developing a strategy, formulating resource needs and implementing teaching. The strategy is based on the concept of application of IT as a tool for design and a medium for representation, management, use and exchange of design information. A course outline has been developed suggesting what could be taught and who could be taught what, how, when and for how long. At the same time, different types of teaching methods are being experimented upon. On the basis of these factors, attempts are being made to meet resource needs for software, hardware, teaching and technical support. Various issues and problems have been brought to light e.g. overcoming cost of hardware and software, lack of teaching and technical support, finding time slots in overloaded curriculums, changing existing attitudes towards IT,etc. We have approached these problems in various ways. We liaise closely with architects' offices, and try to use student skills and expertise within the polytechnic. We try to overcome time-slot problems by joint teaching and assessment with other subjects and try to integrate IT/CAD with studio-based design projects by locating computlng facilities inside studios. This paper is a story of how we have set for ourselves a path to follow. This path is by no means rigid and will continuously change with new experiences and the demands of a volatile industry. We have only just begun.

summary In the process of building design, energy performance is often simulated using physical principles of thermodynamics and energy behaviour using elaborate simulation tools. However, energy simulation is computationally expensive and time consuming process. These drawbacks limit opportunities for design space exploration and prevent interactive design which results in environmentally inefficient buildings. In this paper we propose Energy Model Machine (EMM) as a general and flexible approximation model for instant energy performance prediction using machine learning (ML) algorithms to facilitate design space exploration in building design process. EMM can easily be added to design tools and provide instant feedback for real-time design iterations. To demonstrate its applicability, EMM is used to estimate energy performance of a medium size office building during the design space exploration in widely used parametrically design tool as a case study. The results of this study support the feasibility of using machine learning approaches to estimate energy performance for design exploration and optimization workflows to achieve high performance buildings.

summary The demand for sustainable buildings with minimal environmental impact and efficient energy use is increasing. The most effective design decisions for sustainable design can be made in the early design phases, but appropriate tools to explore design alternatives and understand their impacts on building energy performance are not available at this stage of the project. The integration of Building Information Modeling (BIM) and parametric modeling is the new trend of building modeling, which can greatly benefit sustainable building design. This research introduces an innovative tool to facilitate integrated parametric BIM and to enhance its applications towards creative, sustainable building design through simulation and optimization. The created tool, Revit2GBSOpt, integrates parametric BIM and building energy performance simulation and enables designers to generate alternative options in BIM to explore the energy performance simulation results automatically. Finding the optimized solution, the BIM model will be updated.

title Interdisciplinary Intersections: New roles for digital technologies and landscape architecture in the design of large scale infrastructures

summary The introduction of BIM is assumed to introduce higher degrees of collaboration and efficiencies within design and construction practices. The potentials of this collaboration tend to focus on architecture, engineering and construction (AEC). Landscape architecture is rarely discussed within this model, technically nor conceptual. This paper explores the potentials of landscape architecture’s contribution to this new model of digitally driven collaboration. Drawing on interviews with the architects, landscape architects and engineers we explore the role of landscape architecture in the conceptualization, design and construction of the Victorian Desalination Plant, a highly political project located on an ecological sensitive coastal site. This paper highlights the centrality of the landscape digital model in mediating the critical intersection between the design parameters, physical attributes of the site, performative qualities of the design and the disciplines of architecture, landscape and engineering. This model also formed the dominant method for communicating the complex project to stake holders and clients. Significantly, this model was not developed into a BIM model, with content instead integrated into the architectural and engineering models. This research highlights one of the major difficulties in conceptualizing the positioning of landscape architecture within a BIM driven collaborative process. To operate effectively, landscape architecture must engage across the multiple scales and disciplinary intersections. Consequently, landscape architects must understand the digital and spatial languages of architecture and engineering, and conceptualise where their contribution lies within ‘paperless’ design and construction processes. This outcome differs significantly from current debates within landscape architecture which instead focus on the identification of ‘the’ specialist BIM software most appropriate to the discipline, as distinct from understanding BIM as a collaborative process.

summary Symmetry plays a key role in simplifying the control of legged robots and in giving them the ability to run and balance. The symmetries studied describe motion of the body and legs in terms of even and odd functions of time. A legged system running with these symmetries travels with a fixed forward speed and a stable upright posture. The symmetries used for controlling legged robots may help in elucidating the legged behavior of animals. Measurements of running in the cat and human show that the feet and body sometimes move as predicted by the even and odd symmetry functions

source Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 268-275
summary The paper describes a process where digital measuring survey data is transferred into 3D building model to be used as a foundation for renovation design. The process and method is tested in a case study of an office building of 8 floors. Measuring survey data is more often documented to 2D plan drawings, whereas 3D-modelling was more preferable in the case project. The final aim of the case project is to further test building product model or building information model (BIM) based design methods in building renovation. Product modelling is one emerging framework to manage building related information in contemporary design & construction. Model based methods are more commonly used in new buildings, whereas renovation is usually done with more traditional techniques. Case project results underline the importance of measuring and modelling definition phase. Measuring and documenting objectives for 3D-model based design work are different than for traditional design work. Measuring survey has to be done under the coordination of the designer participants. Selecting and informing the proper and capable surveying partners is also important.

summary Exploring the duality of pervasive computing and architecture in order to propose new models of interaction between people and their built environment. One of the unique "affordances" of digital media is interactivity. This word has come to stand for all manners of engagements between people and things but as McCollough (2004) reminds us the word implies deliberation over the exchange of messages. "Objects" or architecture would be exempt from this mode of communication since, in a likewise manner, we don't interact with a door, we simply open it. However, computing provides a reflexive twist for it is not only the means through which we indirectly communicate with others but also a subject with which we can directly interact. They solicit information and based on the deliberation we ask them for return responses. This quality of computing, especially as it becomes pervasive, has profound implications for architecture and urbanism. When computation becomes embedded into the very materials we build, they along with their nature as inanimate objects become questionable. Our environment itself becomes the interactive subject through which we can inquire about our condition, perform diagnostic tasks or most significantly converse to discover more about our surrounding and ourselves.

summary This paper presents an experiential design concept as one of the approaches to design a good storytelling in VEs. We tested this concept and related it within cubism art to understand spaces based on its original form particularly the shapes, planes and volumes. This experiment revealed elements of expression and abstractions through layers of intrinsic knowledge within the VEs that were extremely difficult to understand when viewed in their original forms. New spaces were also discovered within the VEs thus suggesting evidence on the stories within the art form. This paper also suggested that VEs provide a better understanding of spaces and abstract spaces, scale through different depth of illusions and spatial representation.

summary Designers work in groups. They need to share information either synchronously or asynchronously as they work with parametric modeling software, as with all computer-aided design tools. Receiving information from collaborators while working may intrude on their work and thought processes. Little research exists on how the reception of design updates influences designers in their work. Nor do we know much about designer preferences for collaboration. In this paper, we examine how sharing and receiving design updates affects designers’ performances and preferences. We present a system prototype to share changes on demand or in continuous mode while performing design tasks. A pilot study measuring the preferences of nine pairs of designers for different combinations of control modes and design tasks shows statistically significant differences between the task types and control modes. The types of tasks affect the preferences of users to the types of control modes. In an apparent contradiction, user preference of control modes contradicts task performance time.

summary Cities are growing out of control and with unforeseen complexity, with a lavish energy waste and an increasing life-quality loss. A possible approach to cope with these difficulties is the use of Urban Dynamic Analysis, a multidisciplinary body of knowledge allowing the holistic study of time-relationships between city structures and their related distinctive functions. A set of computer-aided tools is being developed following these guidelines. They are intended for the assessment of the behaviour of morphological layouts as regards to energy saving. Three such tools are described, using different pixel-counting approaches in order to simplify and facilitate their use.

summary Urban sprawl and complexity are increasing at an alarming rate causing huge energetic waste and affecting the quality of life of people and life on earth in general. This paper proposes Urban Dynamic Analysis as a feasible approach to address this negative phenomenon. Urban Dynamic Analysis is a multidisciplinary holistic method that inquires into temporal relations between structures and related characteristics in cities. A range of simulation tools are being adapted and developed aiming to assess different morphological configurations of urban spaces, to improve the welfare of citizens and to optimise energy consumption. All these tools are based on digital image utilization, with simple computational techniques.

title A perceptually based physical error metric for realistic image synthesis
source Alyn Rockwood, editor, SIGGRAPH 99 Conference Proceedings, Annual Conference Series, ACM SIGGRAPH, Addison Wesley
summary We introduce a new concept for accelerating realistic image synthesis algorithms. At the core of this procedure is a novel physical error metric that correctly predicts the perceptual threshold for detecting artifacts in scene features. Built into this metric is a computational model of the human visual system's loss of sensitivity at high background illumination levels, high spatial frequencies, and high contrast levels (visual masking). An important feature of our model is that it handles the luminance-dependent processing and spatiallydependent processing independently. This allows us to precompute the expensive spatially-dependent component, making our model extremely efficient. We illustrate the utility of our procedure with global illumination algorithms used for realistic image synthesis. The expense of global illumination computations is many orders of magnitude higher than the expense of direct illumination computations and can greatly benefit by applying our perceptually based technique. Results show our method preserves visual quality while achieving significant computational gains in areas of images with high frequency texture patterns, geometric details, and lighting variations.

summary The approximation of arbitrary two-dimensional curves by polygons is an important technique in image processing. For many applications, the apparent ideal procedure is to represent lines and boundaries by means of polygons with minimum number of vertices and satisfying a given fit criterion. In this paper, an approximation algorithm is presented which uses an iterative method to produce polygons with a small-but not minimum-number of vertices that lie on the given curve. The maximum distance of the curve from the approximating polygon is chosen as the fit criterion. The results obtained justify the abandonment of the minimum- vertices criterion which is computationally much more expensive

summary The rapid development of digital technology has made architecture a succession of different evolutionary design methodologies. As a result, the rise of computationally driven processes has gain popularity in research and shows a great potential to dramatically improve the design process and productivity that evoke innovations in design practices wherein computer-based project plays a vital role. However, as these technologies rapidly develops and increasingly used in practice, there is a realization that substantial organizational and technological barriers exist that inhibit the effective adoption of these technologies in architectural practices wherein complex projects are being handled. Undeniably it happens in small architectural practices whereby resources are very limited. Relevant literature of the subject shows that research in innovations in manufacturing, product design, technology, construction and engineering practices is substantially conducted but research in digital innovation in design practices is very limited. This paper investigates the factors that impede the effective adoption of emerging digital technologies for the efficient delivery of design projects that are computationally and digitally driven. This involves evaluating digital technologies, technical, financial and organizational barriers when digital innovation is implemented. In order to gain insights of these issues, a pilot study was conducted from several small architectural organizations, and found out relevant attributes and pattern of variables that can be used in establishing a framework for digital innovation.

summary In the era of communication, the participation in internet-communities has grown to become a motor for innovation in software and community platforms. The paper describes the hypothesis that, by creating a virtual city (or a second city) a new type of social, economic and scientific network is established, which is supported through visual communication technologies. The various users bring, per se, their own intrinsic motivation and requirements to the system. Nonetheless, a personal identification with a city/neighbourhood/house/apartment can be used to awake awareness and to foster participation. This is especially important when dealing with the city inhabitants. City modelling itself has been carried out for over a decade. Projects such as the city model of Graz have shown how city models can be established so as to be scalable for new information (Dokonal et al 2000). Furthermore, these city models have been used in the education of future architects and urban planners. The project described here moves in the opposite direction: the model moves out of the classroom to an interdisciplinary city-model-platform. The work described here is the conceptual model for a multi-dimensional data set that models the city. This has spawned a host of other projects using the model as a foundation for further interactivity development and the extension of the model itself. The paper describes the structure of the conceptual model and the first experience of incorporating diverse projects such those mentioned above. The model also is structured so as to be compatible with the XML standards being developed for city information (CityGML). The goal of the project is to create a data set describing the city that not only describes the geometry, but also the history (including planned histories) and nature of the city. In contrast to virtual realities, which attempt to create a separate world (e.g. Second Life), the Second City is intended as an interdisciplinary repository for the geometrical, historical and cultural information of the city.

summary Architectural discourse has recently suggested a new material practice derived from advances in the field of synthetic biology. As biological organisms can now be designed and engineered for specific purposes, it is expected that, in the near future, it will be possible to program even more complex biologically based systems. One potential application is to literally grow buildings by programming cellular organisms to fabricate and deposit material into architecturally relevant patterns. Our current design methods do not anticipate the potentially challenging material practice involved in a biologically engineered architecture, where there is a loose and emergent relationship between design and material articulation. To tackle this conflict, we developed SynthMorph, a form-finding computational tool based on basic biological morphogenetic principles. A reflection is offered on its use, discussing the effect of multicellular morphogenesis on the production of shape. We conclude that such a strategy is an adaptive design method in two ways: (a) the mechanics of design using morphological constraints involve a practice of dynamic and continuous negotiation between a design intent and material emergence, and (b) the proposed design strategy hints at the production of a biologically produced architecture, which would potentially behave as an adaptive organism.

title Bacterial Hygromorphs: Experiments into the Integration of Soft Technologies into Building Skins
source ACADIA // 2016: POSTHUMAN FRONTIERS: Data, Designers, and Cognitive Machines [Proceedings of the 36th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-77095-5] Ann Arbor 27-29 October, 2016, pp. 244-253
summary The last few years have seen an increase in the interest to bring living systems into the process of design. Work with living systems, nonetheless, presents several challenges. Aspects such as access to specialists’ labs, samples of living systems, and knowledge to conduct experiments in controlled settings become barriers which prevent designers from developing a direct, material engagement with the material. In this paper, we propose a design methodology which combines development of experiments in laboratory settings with the use of what we call material proxies, which refer to materials that operate in analogue to some of the behaviors observed in the target organism. We will propose that combining material proxies with basic scientific experimentation constitutes a form of direct material engagement, which encourages richer exploration of the design domain. We will develop this argument by reporting on our experience in designing and delivering the primer component of a themed design studio, structured around bacterial spores as hygroscopic components of building facades. The six-week design project asked students to consider the behavior of bacterial spores, and to imagine a number of systems in which they could be employed as actuators of a membrane system that responded to fluctuations in humidity. The module is interesting in that it negotiates some of the challenges often faced by designers who want to develop a material engagement with living systems, and to produce informed speculations about their potential in architectural design.

summary This article describes the methods of an inclusive design project developed by FACAMP’s NIEDA , as demanded by the UNICAMP Science Museum (Brazil). The objective was to create a multi-sensorial interface that would be capable of describing the process of energy generation and distribution in a hydro-power plant. It began with a scheme based on images and a narration was built out of audible and tactile systems so that it would be comprehensible for the blind public as well, without compromising the aesthetic and informative aspects. It also reveals the challenge of combining the use of multiple technological resources, such as 3D printing and laser cutting.

title Do Analógico ao Digital? [From analog to digital?]
source SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary After admitting that the immersion of Architecture in digital environment happened in the last decade of the XX Century, this paper argues about the (im)possible links established between analogical and digital worlds. Discarding the possibility of a “transition” between them, the paper points the existence of a “jump” that, more than to tie, unlinks them leaving an emptiness that has to be analyzed. Coexisting in this emptiness we find hybrid structures of pragmatic approach, ruptures of paradigms and sprouting of new forms to project and to make architecture. Clarify this panorama is a basic task we need to do before facing the future, not only in a professional way, but also in the field of architectural education, because we have to know which architecture we desire to transmit.

source International Journal of Architectural Computing vol. 9 - no. 2, 115-132
summary This paper presents the design project “it’s a SMALL world”, an exhibition design developed for the Danish Design Centre in 2009.The project investigates the making of a generative design environment by which multiple design parameters as from program, site or the subsequent digital fabrication and assembly process can be negotiated. In this paper we discuss methods for understanding the emergent interrelationships between encoded parameters, how to manage these and their impact on design.The implementation of the design necessitated a novel design method that allowed to blend the qualities of a generative design approach, that can adapt through recursion gradually to local requirements, with explicit definitions.The project showcases with its new developed manufacturing system for non- standard element how customized digital design and production tools allow for a novel nearness to material and new ways of production and collaboration of architects, engineers and the crafts.

title An Architecture Model for Multimodal Interfaces with Force Feedback I.14 Virtual Reality 2
source Proceedings of the Sixth International Conference on Human-Computer Interaction 1995 v.I. Human and Future Computing pp. 455-460
summary Multimodal interfaces with force feedback pose new problems both in terms of their design and for hardware and software implementation. The first problem is to design and build force-feedback pointing devices that permit users both to select and manipulate interface objects (windows, menus and icons) and at the same time feel these objects with force and precision through their tactile and kinesthetic senses. The next problem is to model the interface such that it can be returned to the user via force-feedback devices: the task is to define the fields of force corresponding to interface objects and events, and to design algorithms to synthesize these forces in such a way as to provide optimum real-time operation. The final problem concerns the hardware and software architecture to be used to facilitate the integration of this technology with contemporary graphic interfaces. An architecture model for a multimodal interface is presented: it is based on the notion of a multiagent model and breaks down inputs and outputs according to multiple modalities (visual, auditory and haptic). These modalities are represented by independent software components that communicate with one another via a higher-level control agent.

summary This paper proposes the application of some well known two-dimensional geometrical shape descriptors for the visualisation of the structure of architectural open spaces. The paper demonstrates the use of visibility measures such as distance to obstacles and amount of visible space to calculate shape descriptors such as convexity and skeleton of the open space. The aim of the paper is to indicate a simple, objective and quantifiable approach to understand the structure of open spaces otherwise impossible due to the complex construction of built structures.

summary The first great consideration in design is that the human world is irreducibly phenomenal; we are immersed in the overwhelming richness and sensuousness of the physical environment. And the first great task of design education is to put the student of design into a disciplined awareness of that phenomenal world, by development of categories of discrimination. The introductory experiences bring the student into vivid contact with compelling phenomena. The associated exercises structure and differentiate perception of nuance within these.

There is little doubt that texture, surface, extension, value, and color are in one sense basic categories of physical phenomena, constituting in essence a fundamental stratum of experience and the sensible world. Modern psychology and epistemology, however, cohere in saying that this stratum is not the sense world of everyday, the primary datum of the functioning societal member. Neither is the abstract world of the physicist's concepts an everyday world. What is given in our day-to-day life is neither very abstract, nor very concrete, but a sort of functionally-bound middle world of norms and stereotypes.

It takes the disciplined seeing characteristic of foundational training in the arts to drive this bourgeois view of physical reality back to elemental sense data. Just as it requires the supremely abstract language of mathematics and the rarified "experience" of modern scientific experimentation to drive that same view offcenter in the direction of abstraction. The first exercises of a program of design education begin to perform the former role.

title From Ramon Llull to Image Idea Generation
source International Conference on Generative Art
summary Our minds follow familiar well trodden paths, and we sometimes need mechanical help to find new, undiscovered thoughts and ideas. Ramon Llull was a Christian philosopher who used a mechanical way of investigating truth, a set of concentric wheels on which words were written. By rotating the wheels, the words were combined in unexpected ways. A similar technique has been (re-)invented, randomised and changed by Edward de Bono and is called Lateral Thinking. Can we apply this technique to image idea generation? This paper describes a first attempt at building an image idea generator for use by artists and non-artists alike, and sets out plans for a new a more powerful version. An image idea generator takes no (or very few) instructions from the user and creates a set of images from which the user chooses those he likes best. The purpose of an image idea generator is to easily create previously un-thought of images, to easily explore the 2D world of color and form.

title Possible Futures in Computer Art Generation
source International Conference on Generative Art
summary Years of trying to create an "Image Idea Generator" program have convinced me that the perfect solution would be to have an artificial artistic person, a design slave. This paper describes how I came to that conclusion, realistic alternatives, and briefly, how it could possibly happen. 1. The history of Repligator and Gliftic 1.1 Repligator In 1996 I had the idea of creating an “image idea generator”. I wanted something which would create images out of nothing, but guided by the user. The biggest conceptual problem I had was “out of nothing”. What does that mean? So I put aside that problem and forced the user to give the program a starting image. This program eventually turned into Repligator, commercially described as an “easy to use graphical effects program”, but actually, to my mind, an Image Idea Generator. The first release came out in October 1997. In December 1998 I described Repligator V4 [1] and how I thought it could be developed away from simply being an effects program. In July 1999 Repligator V4 won the Shareware Industry Awards Foundation prize for "Best Graphics Program of 1999". Prize winners are never told why they won, but I am sure that it was because of two things: 1) Easy of use 2) Ease of experimentation "Ease of experimentation" means that Repligator does in fact come up with new graphics ideas. Once you have input your original image you can generate new versions of that image simply by pushing a single key. Repligator is currently at version 6, but, apart from adding many new effects and a few new features, is basically the same program as version 4. Following on from the ideas in [1] I started to develop Gliftic, which is closer to my original thoughts of an image idea generator which "starts from nothing". The Gliftic model of images was that they are composed of three components: 1. Layout or form, for example the outline of a mandala is a form. 2. Color scheme, for example colors selected from autumn leaves from an oak tree. 3. Interpretation, for example Van Gogh would paint a mandala with oak tree colors in a different way to Andy Warhol. There is a Van Gogh interpretation and an Andy Warhol interpretation. Further I wanted to be able to genetically breed images, for example crossing two layouts to produce a child layout. And the same with interpretations and color schemes. If I could achieve this then the program would be very powerful. 1.2 Getting to Gliftic Programming has an amazing way of crystalising ideas. If you want to put an idea into practice via a computer program you really have to understand the idea not only globally, but just as importantly, in detail. You have to make hard design decisions, there can be no vagueness, and so implementing what I had decribed above turned out to be a considerable challenge. I soon found out that the hardest thing to do would be the breeding of forms. What are the "genes" of a form? What are the genes of a circle, say, and how do they compare to the genes of the outline of the UK? I wanted the genotype representation (inside the computer program's data) to be directly linked to the phenotype representation (on the computer screen). This seemed to be the best way of making sure that bred-forms would bare some visual relationship to their parents. I also wanted symmetry to be preserved. For example if two symmetrical objects were bred then their children should be symmetrical. I decided to represent shapes as simply closed polygonal shapes, and the "genes" of these shapes were simply the list of points defining the polygon. Thus a circle would have to be represented by a regular polygon of, say, 100 sides. The outline of the UK could easily be represented as a list of points every 10 Kilometers along the coast line. Now for the important question: what do you get when you cross a circle with the outline of the UK? I tried various ways of combining the "genes" (i.e. coordinates) of the shapes, but none of them really ended up producing interesting shapes. And of the methods I used, many of them, applied over several "generations" simply resulted in amorphous blobs, with no distinct family characteristics. Or rather maybe I should say that no single method of breeding shapes gave decent results for all types of images. Figure 1 shows an example of breeding a mandala with 6 regular polygons: Figure 1 Mandala bred with array of regular polygons I did not try out all my ideas, and maybe in the future I will return to the problem, but it was clear to me that it is a non-trivial problem. And if the breeding of shapes is a non-trivial problem, then what about the breeding of interpretations? I abandoned the genetic (breeding) model of generating designs but retained the idea of the three components (form, color scheme, interpretation). 1.3 Gliftic today Gliftic Version 1.0 was released in May 2000. It allows the user to change a form, a color scheme and an interpretation. The user can experiment with combining different components together and can thus home in on an personally pleasing image. Just as in Repligator, pushing the F7 key make the program choose all the options. Unlike Repligator however the user can also easily experiment with the form (only) by pushing F4, the color scheme (only) by pushing F5 and the interpretation (only) by pushing F6. Figures 2, 3 and 4 show some example images created by Gliftic. Figure 2 Mandala interpreted with arabesques   Figure 3 Trellis interpreted with "graphic ivy"   Figure 4 Regular dots interpreted as "sparks" 1.4 Forms in Gliftic V1 Forms are simply collections of graphics primitives (points, lines, ellipses and polygons). The program generates these collections according to the user's instructions. Currently the forms are: Mandala, Regular Polygon, Random Dots, Random Sticks, Random Shapes, Grid Of Polygons, Trellis, Flying Leap, Sticks And Waves, Spoked Wheel, Biological Growth, Chequer Squares, Regular Dots, Single Line, Paisley, Random Circles, Chevrons. 1.5 Color Schemes in Gliftic V1 When combining a form with an interpretation (described later) the program needs to know what colors it can use. The range of colors is called a color scheme. Gliftic has three color scheme types: 1. Random colors: Colors for the various parts of the image are chosen purely at random. 2. Hue Saturation Value (HSV) colors: The user can choose the main hue (e.g. red or yellow), the saturation (purity) of the color scheme and the value (brightness/darkness) . The user also has to choose how much variation is allowed in the color scheme. A wide variation allows the various colors of the final image to depart a long way from the HSV settings. A smaller variation results in the final image using almost a single color. 3. Colors chosen from an image: The user can choose an image (for example a JPG file of a famous painting, or a digital photograph he took while on holiday in Greece) and Gliftic will select colors from that image. Only colors from the selected image will appear in the output image. 1.6 Interpretations in Gliftic V1 Interpretation in Gliftic is best decribed with a few examples. A pure geometric line could be interpreted as: 1) the branch of a tree 2) a long thin arabesque 3) a sequence of disks 4) a chain, 5) a row of diamonds. An pure geometric ellipse could be interpreted as 1) a lake, 2) a planet, 3) an eye. Gliftic V1 has the following interpretations: Standard, Circles, Flying Leap, Graphic Ivy, Diamond Bar, Sparkz, Ess Disk, Ribbons, George Haite, Arabesque, ZigZag. 1.7 Applications of Gliftic Currently Gliftic is mostly used for creating WEB graphics, often backgrounds as it has an option to enable "tiling" of the generated images. There is also a possibility that it will be used in the custom textile business sometime within the next year or two. The real application of Gliftic is that of generating new graphics ideas, and I suspect that, like Repligator, many users will only understand this later. 2. The future of Gliftic, 3 possibilties Completing Gliftic V1 gave me the experience to understand what problems and opportunities there will be in future development of the program. Here I divide my many ideas into three oversimplified possibilities, and the real result may be a mix of two or all three of them. 2.1 Continue the current development "linearly" Gliftic could grow simply by the addition of more forms and interpretations. In fact I am sure that initially it will grow like this. However this limits the possibilities to what is inside the program itself. These limits can be mitigated by allowing the user to add forms (as vector files). The user can already add color schemes (as images). The biggest problem with leaving the program in its current state is that there is no easy way to add interpretations. 2.2 Allow the artist to program Gliftic It would be interesting to add a language to Gliftic which allows the user to program his own form generators and interpreters. In this way Gliftic becomes a "platform" for the development of dynamic graphics styles by the artist. The advantage of not having to deal with the complexities of Windows programming could attract the more adventurous artists and designers. The choice of programming language of course needs to take into account the fact that the "programmer" is probably not be an expert computer scientist. I have seen how LISP (an not exactly easy artificial intelligence language) has become very popular among non programming users of AutoCAD. If, to complete a job which you do manually and repeatedly, you can write a LISP macro of only 5 lines, then you may be tempted to learn enough LISP to write those 5 lines. Imagine also the ability to publish (and/or sell) "style generators". An artist could develop a particular interpretation function, it creates images of a given character which others find appealing. The interpretation (which runs inside Gliftic as a routine) could be offered to interior designers (for example) to unify carpets, wallpaper, furniture coverings for single projects. As Adrian Ward [3] says on his WEB site: "Programming is no less an artform than painting is a technical process." Learning a computer language to create a single image is overkill and impractical. Learning a computer language to create your own artistic style which generates an infinite series of images in that style may well be attractive. 2.3 Add an artificial conciousness to Gliftic This is a wild science fiction idea which comes into my head regularly. Gliftic manages to surprise the users with the images it makes, but, currently, is limited by what gets programmed into it or by pure chance. How about adding a real artifical conciousness to the program? Creating an intelligent artificial designer? According to Igor Aleksander [1] conciousness is required for programs (computers) to really become usefully intelligent. Aleksander thinks that "the line has been drawn under the philosophical discussion of conciousness, and the way is open to sound scientific investigation". Without going into the details, and with great over-simplification, there are roughly two sorts of artificial intelligence: 1) Programmed intelligence, where, to all intents and purposes, the programmer is the "intelligence". The program may perform well (but often, in practice, doesn't) and any learning which is done is simply statistical and pre-programmed. There is no way that this type of program could become concious. 2) Neural network intelligence, where the programs are based roughly on a simple model of the brain, and the network learns how to do specific tasks. It is this sort of program which, according to Aleksander, could, in the future, become concious, and thus usefully intelligent. What could the advantages of an artificial artist be? 1) There would be no need for programming. Presumbably the human artist would dialog with the artificial artist, directing its development. 2) The artificial artist could be used as an apprentice, doing the "drudge" work of art, which needs intelligence, but is, anyway, monotonous for the human artist. 3) The human artist imagines "concepts", the artificial artist makes them concrete. 4) An concious artificial artist may come up with ideas of its own. Is this science fiction? Arthur C. Clarke's 1st Law: "If a famous scientist says that something can be done, then he is in all probability correct. If a famous scientist says that something cannot be done, then he is in all probability wrong". Arthur C Clarke's 2nd Law: "Only by trying to go beyond the current limits can you find out what the real limits are." One of Bertrand Russell's 10 commandments: "Do not fear to be eccentric in opinion, for every opinion now accepted was once eccentric" 3. References 1. "From Ramon Llull to Image Idea Generation".

summary This paper is situated in a specific research by design setting, where the realised work of architecture has been generated with digital tools operated by analogue minds of designers. It examines the relation- ship between the two entities, the designer and the tools, in an attempt to understand their specific roles better, trusting that this can lead to anew ways of enhancing the design process. Through revisiting the processes, methods, techniques and tools employed within various design-cycles of the project, authors present their own /designerly/ experience, pointing to both the potentials and limitations of the digital tools used. The attention is drawn to the importance for a human designer to have a critical awareness of the true nature of the computational systems and the capacity of both to adapt to the given context, in order to be able to embrace them and use to their full potentials.

The author looks at how predication is represented in such a system when it is used for cognitive modeling and natural- language understanding and generation. In particular, the author discusses issues in the representation of fictional entities and the representation of propositions from fiction, using SNePS. A brief survey is given of four philosophical ontological theories of fiction and sketch an epistemological theory of fiction (implemented in SNePS) using a story operator and rules allowing propositions to 'migrate' into and out of story 'spaces.'

summary The continuing development of Rapid Prototyping technologies and the introduction of Concept Modelling technologies means that their use is expanding into a greater range of applications. The primary aim of this paper is to give the reader an overview of the current state of the art in Layered Manufacturing (LM) technology and its applicability in the field of architecture. The paper reports on the findings of a benchmarking study, conducted by the Rapid Design and Manufacturing (RDM) Group in Glasgow [G.J. Ryder, A. McGown, W. Ion, G. Green, D. Harrison, B. Wood, Rapid Prototyping Feasibility Report, Rapid Prototyping Group, Glasgow School of Art, 1998.], which identified that the applicability of LM technologies in any application can be governed by a series of critical process and application specific issues. A further survey carried out by the RDM group investigated current model making practice, current 3D CAD use and current use of LM technologies within the field of architecture. The findings are then compared with the capabilities of LM technologies. Future research needs in this area are identified and briefly outlined.

summary This paper presents a new computer model for city skyline simulation. It works by shaping medium and high-rise buildings to their best performance. This new tool was conceived to simulate and analyze cities where tall buildings are emerging on pre-existing urban schemes with irregular geometry and where inter-building spacing is proportional to the height of built blocks. The model is based on two main inputs, namely: the description of the network formed by land subdivision of the actual or irregular urban schemes, and the building regulations quantitative parameters based on solar obstruction angles and maximum usability rates. By combining data from these inputs, the computer model presents the dimensions of the building envelop for maximum profitability of each plot. That way the architect will immediately know the number of floors that leads to the maximum built area, for certain plots. In addition to this, the built blocks images are presented in the screen, as well as corresponding tables and Cartesian graphs. Furthermore, this model can also be used for analyzing city skyline for large urban areas. This analysis can range from a mere visual inspection of the variety of images built blocks will take under different legal constraints, to a more intricate analysis of how city skyline and built area, amongst others, are affected by different the regulations.

summary Systems of feedback loops and cybernetic methods have influenced for decades the production and consumption networks and supply and demand chains in computer-integrated manufacturing. These mechanisms contribute to the increased efficiency of production, expanding the ability of both manufacturers and production engineers to create a workplace with smoother supply-chain management, as well as economies of scale and scope that are contingent on increased capitalism in a networked, globalized world. Mobility and flexibility are both physical and philosophical imperatives, aided by new small-scaled controls such as handheld wireless devices, which also contribute to a rising culture of nomadism. The shrinking scale of technologies and facilities has provided the mobile worker with numerous opportunities within complexly networked systems, forming a new paradigm for urban production spaces of the future. This paper is an investigation of how technology is changing and reshaping the architectural potentials for the contemporary industrial workplace.

title Design Specification Representation and Analysis

summary The conventional structures of decision tables, information networks, and outlines define the current methodology for the representation and use of design specifications. This paper explores the relationships at the interfaces between these three representational tools. New analysis strategies are presented that provide flexibility at the lower boundary of the information network by converting decision tables to subnetworks within the information network and by compressing multiple subtables into larger tables representing higher- level nodes in the network. Both generation and compression of the information network provide flexibility in organizing a specification. The ability to both generate and compress nodes and subnodes establishes a mean of representing all the relations among the data items of a specification and gives one more direct control over the level of detail of the information network. As a direct consequence of the ability to generate new nodes, new classifiers can be progressively attached to the nodes of the subnetwork, as well as to the nodes in the information network. As a result, specification requirements are more logically identified by the outline and requirements and data items which were previously hidden within decision table conditions and actions are now directly accessible from the outline. Conversely, items inconsequential to the outline can be compressed into nodes and removed from the outline. A computer program is presented that implements these network transformations. The program accurately represents the interface between the network and the decision table

source Electronic Computation Conference Proceedings (8th : 1983 : Houston, TX). American Society of Civil Engineers, pp. 559-571. CADLINE has abstract only
summary This paper proposes a database schema that supports structural engineering design of buildings. An evaluation and comparison of hierarchical, network, and relational databases shows that relational databases are especially suited to a structural engineering design database. The proposed database schema represents the complex relationships between the components of a building-design database. The schema consists of a structural system hierarchy that relates abstract database components to basic building elements. In addition, it combines topology with attributes to achieve an integration that allows the representation of a broad range of common building configurations and structural systems. The user can combine a basic set of constructs to generate either a general or a very detailed description of a structure. The high degree of integration of topology and attributes yields a database that possesses desirable relational characteristics. The database provides efficient access to components based both on their location and on their attribute values. It also allows the user to add, delete, retrieve, and modify database components and values. The versatility and flexibility of the relational model make it a useful tool for managing building engineering data

title Constraint Enforcement in a Structural Design Database
source Journal of the Structural Division. American Society of Civil Engineers, December, 1986. vol. 112: pp. 2565-2577
summary During the design of a commercial structure, large amounts of information pertaining to all aspects of the design must be stored, accessed, and operated upon. A database management system (DBMS), composed of a central repository of data and the associated software for controlling accesses to it, provides one way to generate, represent, manage, and use this information. However, DBMSs are not presently structured in such a way that they can flexibly represent complex engineering constraint relationships, including those defined by codes, standards, and specifications. This paper examines structural design constraints and addresses the question of how they can be incorporated into DBMSs. It presents four representations of engineering constraints: the text of a design specification, the equations extracted from the specification, the dependency network among the constrained data items, and a relational DBMS model. The database model was implemented using a commercially available DBMS and the limitations of the implementation are explored. What is new in this DBMS model is that a constraint dependency subnetwork is associated directly with the stored data that it constrains. The implemented result is a new abstraction, consisting of a relation and a set of computations and checks, that enforces the relationships embodied in the dependency network. The database user need only initially define a set of rules and computed attributes. These are then used by the DBMS to automatically perform the appropriate checks and assignments. The database user is, to a significant degree, free of constraint checking concerns because the system itself knows what to do

summary The American Institute of Steel Construction 'Specification for the Design, Fabrication, and Erection of Structural Steel Buildings' has made manual steel column design exceedingly time consuming and difficult. The objective of this paper is to present a simplified method of designing steel columns subjected to axial loads and moments for use in situations where automated design methods are inappropriate. Steel column design is based on the interaction equations of the AISC Specification. These equations are presented in terms of actual and allowable stresses and much time is required by a designer to manually determine the stresses and solve the equations. To simplify their solution, the interaction equations were reformulated and a set of parameters (multipliers) was introduced into them. The parameters were investigated to determine their validity, limits, and ranges of significant influence. They were then tabulated to provide quick and easy access for use. The modified interaction equations and the tabulated parameters constitute the results of this study. They are the physical tools that enable a designer to rapidly select initial steel column sections to satisfy design requirements and specification constraints. The analysis confirms that these tools can realistically and accurately be determined. The equations were algebraically derived and the tables were generated as a function of the properties of the sections. Thus, a new design method, combining the use of tabulated parameters with algebraically modified interaction equations, has been developed. This method greatly simplifies and speeds up the column section selection process

title Maintenance of Integrity During Concurrent Access in a Building Design Database
source Computer Aided Design. Butterworth Scientific Ltd., July, 1982. vol. 14: pp. 201-207. includes bibliography
summary This paper proposes a building design database model that insures database integrity in a highly flexible relational structure while supporting disciplinary and interdisciplinary concurrent use. The model strongly supports designer-database interaction by providing extremely versatile data access mechanisms and an associated concurrency control mechanism. Building design components are represented in terms of their location, their attribute values, and combinations of the two. Both the logical and physical database models are illustrated. The relational model is vital for achieving the greatest flexibility in representing and accessing building design data. Its standard relations are ideal for information representation. In addition, the operators provided by the model enable the engineer to readily restructure the database to support building design needs. This paper introduces a database structuring mechanism referred to as catalogs. Catalogs provide a highly versatile mechanism for accessing database information by grouping building components into data units called modules. The modules provide convenient access to multiple design entities. Also included is a protection relation that provides a concurrency control environment for the catalog relations. The module concept is particularly important in design because it enables the ad hoc groupings of data which are so often necessary to support the design process. The module is recommended as the level to which a locking concurrency control mechanism be applied. It is a small enough data unit to support concurrency for interdisciplinary design activities, yet not so small as to require extensive overhead in the concurrency control implementation. Two different modes of locking are recommended for the catalog relations of a building design database to achieve maximum concurrency and efficiency of access by designers

title Natural Language Prototypes for Analyzing Design Standards
source Southampton, U.K: Computational Mechanics Publications, 1987. pp. 147-160
summary CADLINE has abstract only. This paper addresses the use of natural language processing for acquiring, processing, and representing knowledge from design standards. A standard is a set of provisions providing principles, models, rules, limits, and particulars that are established by some authority for some purpose. In their textual form as written documents, design standards cannot directly be used in computer-aided design (CAD) systems. This paper demonstrates how standards can be transformed, using natural language processing techniques, from their textual form to alternative representations that more readily lend themselves to use in computer-aided design systems, supporting a variety of design applications. The language being transformed is the Building Officials and Code Administrators Building Code, one set of requirements that govern the design of buildings. Prototype computer subsystems have been developed that transform natural language sentences to case-grammar format and finally to subject-relationship- object triplets. The three prototypes that achieve these transformations are described: a parser, a semantic analyzer, and a query system. During one processing cycle, the system identifies that data items in a provision and the relationships between the data items. It also interacts with the user to add new data items to its knowledge bases, to verify data items found, and to add to its vocabulary. Alternatively, it responds to natural-language questions about the contents of the standard by identifying the relevant provisions within the standards. Processing formal documents requires knowledge about vocabulary, word-order, time, semantics, reference, and discourse. Despite the relative clarity of formal writing as it occurs in standards, the difficulties of implied responsibility, multiple meanings, and implied data items remain. A long-term research program at North Carolina State University has been defined that builds on these prototypes to further investigate knowledge acquisition and representation for standards

summary Of all the contributions of artificial intelligence (AI), expert systems show some of the most significant promise for engineering applications. An expert system provides a framework for acquiring, representing, and using knowledge about a particular application's domain. The role of knowledge in engineering design merits closer attention so that AI-oriented computer-aided engineering (CAE) systems can be developed and maintained systematically. Because 'knowledge' in engineering applications is loosely defined, it is necessary to identify knowledge types and the correlations between them before widespread engineering design applications can be achieved. The types of domain knowledge; facts, procedures, judgments, and control; differ from the classes of that knowledge; creative, innovative, and routine. Feasible engineering tasks for expert systems can be determined based on these types and classes of knowledge. Prototype expert systems have been developed for civil engineering applications to assist with interpretation, design, planning, diagnosis, control, and other engineering system functions. A number of these are described herein. Interpretive tasks require reasoning about a task in light of the knowledge available, while generative tasks create potential solutions to be tested against constraints. Only after classifying the domain by type and level can the engineer select an appropriate knowledge-engineering tool for the domain being considered. The critical features to be weighed after problem classification are knowledge representation techniques, control strategies, interface requirements, compatibility with traditional systems, and economic considerations. After considering all of these factors in the selection of the expert system took, the engineer can then proceed with the acquisition of knowledge and the construction and use of the expert system

title Generative Engineering Databases - Toward Expert Systems
source Computers and Structures. Pergamon Press, 1985. vol. 22: pp. 11-15
summary CADLINE has abstract only. Engineering data management, incorporating concepts of optimization with data representation, is receiving increasing attention. Research in this area promises advantages for many engineering applications, particularly those which use data innovatively. This paper presents a framework for a comprehensive, relational database management system that combines a knowledge base (KB) of design constraints with a database (DB) of engineering data items to achieve a 'generative database' - one which automatically generates new engineering design data according to the design constraints stored in the knowledge base. Thus, in addition to the designer and engineering design and analysis application programs, the database itself contributes to the design process. The KB/DB framework proposed here requires a database that is able to store all of the data normally associated with engineering design and to accurately represent the interactions between constraints and the stored data while guaranteeing its integrity. The framework also requires a knowledge base that is able to store all the constraints imposed upon the engineering design process. The goal sought is a central integrated repository of data, supporting interfaces to a wide variety of application programs and supporting processing capabilities for maintaining integrity while generating new data. The resulting system permits the unaided generation of constrained data values, thereby serving as an active design assistant. This paper suggests this new conceptual framework as a means of improving engineering data representation, generation, use, and management

summary Pergamon Press, 1985. --- Also Published in : Proceedings of the Symposium on Advances and Trends in Structures and Dynamics, Pergamon Press, George Washington University and the National Aeronautics and Space Administration, Washington, D.C. pp. 11-15, Oct.1984. The rapid advances occurring in interactive micro-computing and computer science have provided the engineer with a powerful means of processing, storing, retrieving, and displaying data. The effective use of computer technology in engineering processes and applications is recognized by many as the key to increased individual, company, and national productivity. The implications of this observation for the academic community are clear: we must prepare our students to use computer methods and applications as part of their fundamental education. The proper tradeoff between engineering fundamentals and computer science principles and practices is changing with many of the concepts of engineering now being packaged in algorithms or on computer chips. The components of an education should include operating system fundamentals, data structures, program control and organization, algorithms, and computer architectures. It is critically important for engineering students to receive an education that teaches them these fundamentals. This paper suggests that to convey the essentials of computer science to future engineers requires, in part, the addition of computer courses to the engineering curriculum. It also requires a strengthening of the computing content of many other courses so that students come to treat the computer as a fundamental component of their work. This is a major undertaking, but new engineers graduating with advanced computing knowledge will provide potentially significant future innovations in the engineering profession

summary The role of computer science is increasing in nearly every engineering discipline. One of the dilemmas in engineering education today is how future engineers can best assimilate the advanced, yet fundamental, knowledge of computer science appropriate for their professional engineering career. This paper suggests that the role of the academic community must be to prepare engineering students to use computer methods and applications as a part of their fundamental engineering education. It is the responsibility of colleges and universities to incorporate contemporary computing fundamentals into their academic curriculum to improve the professional qualifications of their engineering graduates. This paper discusses current educational practices and their shortcomings as well as new options to reinforce and enhance the role of computing in engineering. The key ingredients, operating system fundamentals, data structures, program control and organization, algorithms, and computer architectures (relative to concurrent processing) are discussed. The paper suggests that to convey the essentials of computer science to future engineers requires in part, the addition of computer courses to the engineering curriculum. It also requires a strengthening of the computational content of many others so that the student comes to treat the computer as a fundamental component of his work. Indeed this is a major undertaking but the benefits of advanced computer knowledge by new engineering graduates promises to provide significant future innovations in the engineering profession. The proper tradeoff between engineering fundamentals and computer science is changing with many of the concepts of engineering now being packaged in algorithms or on computer chips. The impact of advances in computer technology on engineering education are therefore discussed. Several of the benefits of enhanced computational expertise by engineers are enumerated and case studies of recent NASA initiatives whose success required that engineers possess an in-depth knowledge of computer science are presented

summary This paper describes a mechanism that enables one to automatically monitor and evaluate the use of engineering design data. The framework, associated with a relational database management system, combines a database with a set of constraints on the use of engineering data. This requires a database that stores all of the data normally associated with engineering design as well as all of the domain-dependent constraints imposed upon the use of the design data. Such a framework has been successfully constructed and is described in this paper. An example, based on constraints extracted from the AISC Specification, is presented and the performance of the framework is discussed. The proposed framework resides between a DBMS and its users and serves as an experienced expert consultant to the users. It embodies the knowledge of the specific domain of interest; in this case, allowable stresses in steel members. Whenever a user retrieves data from the database, the mechanism is activated. It interprets data request, applies the appropriate constraints, and provides the correct data. Its understanding of the semantics of both the data request and its own constraints insures the validity of data it selects to return to the user. All previous database integrity research concentrated on maintaining the integrity of the stored data, i.e., on guaranteeing the integrity of any static state of the database. This paper advocates a mechanism for checking data being retrieved from the database as well as for checking data being inserted into the database. It deals, therefore, with the correctness of data being selected for use

summary Database management systems (DBMS) are an essential component of the computer integrated manufacturing (CIM) environment. A database management system provides a powerful functionality for the storage, management, and use of engineering data. It is lacking, however, in its ability to deal with engineering constraints. In the past, constraint checking was performed by application programs. More recently DBMS's have been incorporating into their structure specifications for enforcing a limited set of integrity constraints and the mechanisms for invoking them automatically. To ensure the correctness of engineering data, an effective constraint management capability must be incorporated into any proposed engineering DBMS. This paper demonstrates how this can be done, proposes a systematic way to classify constraints so that integrity can be maintained efficiently, and discusses a prototype called CDIS which implements the concepts. This paper uses the relational database model to represent both engineering data and engineering constraints. Data integrity is defined and its enforcement through the use of engineering constraints is described. Existing methods for handling constraints are discussed. A new model that enables the engineer to associate design constraints with a relational database is presented and an example is given that demonstrates the model. Extensions to a DBMS to implement the concepts presented are described. No currently available DBMS provides the much needed capabilities proposed here

summary Standards, codes, and specifications play an important role in the design of buildings, bridges, and other engineering systems. A design configuration must be checked against all standards to ensure that it is acceptable. This process of design conformance checking using standards is often very tedious. The successful automation of conformance checking is one of the components of a comprehensive computer-aided design system. In that past, standards were interpreted and converted into application programs written in procedural programming languages such as FORTRAN. This approach is extremely inflexible and often error-prone. To support a fully automated computer-aided design system, standards must be incorporated into the design process in a more generic and flexible manner. This paper investigates the feasibility of alternatively casting standards in a form suitable for processing in a knowledge-based expert system environment. The emergence of expert systems from artificial intelligence research has provided a technology that readily lends itself to the automation of design standards. Knowledge-based expert systems have become a powerful tool in tackling domains like design where some of the problem-solving knowledge is diverse and ill-structured. Using an expert system tool, a standard can be represented and processed independent of a CAD application program. Two prototype standards processing systems utilizing the production system approach have been constructed and are presented herein. Although the obvious direct translation casting the provisions of a standard as rules in a production system has its advantages, a more generic and flexible representation scheme is proposed herein. The approach advocated in this paper is to represent standards as databases of facts which can be readily and generically processed by an expert system. The database representation is derived from a unified view of standards obtained by using the standards modeling tools proposed by previous researchers in this field during the past decade. Building on this existing technology resulted in a knowledge- based standards processing architecture which is generic, modular, and flexible.

summary The operation of a manufacturing organization often depends on its underlying design and manufacturing databases. In a manufacturing environment, many users, both individuals and application programs, must have access to one or more of the organization's databases to provide, use, or modify data, to control information flow, and to facilitate information management. Such databases routinely undergo dynamic changes in both their content and their structure. These changes commonly result from the design of new products, the introduction of new materials, and the introduction of new machines and processes on the shop floor. Such continuing changes must be reflected in the database schemas and subsequently require that application programs be updated and that online users be educated on a continuous basis. The problem addressed in this paper is that it is difficult for users and application programs to get the information that they need, when they need it, from the multiple heterogeneous database management system (DBMS) environments that have evolved in design and manufacturing organizations. The solution proposed here is to build a general, extendable interface between database users and the many sources of data available to them. This in itself is not a new suggestion; a number of researchers have addressed portions of this problem. In general, the interfaces that they have developed to date are best suited to environments where the structure of the database is static and does not change over time. One of the things that this paper proposes that is different from existing work is an interface which handles the dynamic restructuring nature of manufacturing databases, enabling a user to obtain the most accurate and up to date information as the structure and content of the underlying databases change. Another unique aspect of the DBMS interface proposed herein is that the interface attempts to capture the knowledge that an experienced human user incorporates in his search for data in a database, i.e., it seeks to identify and use the generic knowledge needed to operate a DBMS. This knowledge is used by the interface to enable both the online users and the application programs to request data without knowing the data's location or precisely how to ask for it. Further, the interface makes use of mechanisms that allow the user to request data without knowing the exact identity of the required entities that are stored in the database

source London, UK: Chapman and Hall Ltd., 1987. pp. 267-295
summary Building design, construction, operation, maintenance, and control are all processes that have achieved various levels of computer use. Although the degree of computerization varies significantly, one common aspect of the computing needs of each process is an abundance of data in the form of tables, standards, project definition information, catalogs, etc. In most cases this data is stored in files which are independently used for input to stand-alone single-process application programs, such as a structural analysis application. The utility of these independent files is therefore limited to a single application. As concepts of integration of engineering applications evolved, the use of databases and database management systems (DBMS) increased. A number of issues of significant concern emerged. First, there is a need to retrieve data from many independent, possibly widely distributed databases. Second, there is a need for a uniform means of doing so. Third, such databases routinely undergo dynamic change. Changes in a database schema commonly result from the evolution of a design, from changes in the design process itself, and from changes in other subsequent downstream processes. Such continuing changes must be reflected in the database schemas and they subsequently require that application programs be updated and that online users be educated on a continuing basis. This chapter describes a knowledge-based expert system that provides access to and integration of the many underlying databases needed to support the building design/construction process. The unique aspect of the expert system presented in this chapter is its capture of the knowledge that an experienced human user incorporates in his search for data in a database, i.e., it seeks to identify and use the generic knowledge needed to operate a DBMS to retrieve data. This knowledge is used by the interface to enable both the online users and the application programs to request data without knowing the data's location or precisely how to ask for it. Further, the interface makes use of mechanisms that allow the user to request data without knowing the exact name by which it is stored in the database. In doing so it formalizes the levels of complexity of that knowledge and points out the multidisciplinary applications of the research results

summary Database management systems (DBMSs) are in widespread use because of the ease and flexibility with which they enable users to access large volumes of data. The use of DBMSs has spread from its origin in business applications to scientific and engineering applications as well. As engineers rely more and more on the computer for data storage, our ability to manually keep track of relationships between data and to ensure data accuracy is severely limited. The inherent fluctuations in engineering design data as well as its large volume, increase the difficulty of doing so. Ensuring data accuracy through the use of integrity constraints which limit or constrain the values of the data is a central aspect of DBMS use. Enforcing constraints (to the extend possible) is a job for the DBMS. This alleviates some of the burden placed on the user and database administrator to maintain the integrity of the database. In addition, it enables integrity constraints to be conceptually centralized and made available for inspection and modification instead of being scattered among application programs. Despite their importance, however, capabilities for handling integrity constraints in commercial DBMSs are limited and they lack adequate integrity maintenance support. In addition, a comprehensive theoretical basis for such support-the role of a constraint classification, representation, invocation, and use methodology-has yet to be developed. This paper presents a formalism that classifies semantic integrity constraints based on the structure of the relational database model. Integrity constraints are characterized by the portion of the database structure they access, whether one or more relations, attributes, or tuples. Thus, the model is completely general, allowing the identification, definition, and arbitrary specification of any constraint on a relational database. It also provides a basis for the implementation of a database integrity subsystem. Examples of each type of constraint are illustrated using a small engineering database, and various implementation issues are discussed

summary This paper discusses the use of a relational database for representing the data gathered and derived during the building design process. In doing so, it considers the complexity of the relationships among a structure's topology, geometry, and attributes, and the critical requirements they impose on the development of a building design database. In the broad arena of computer-aided design, relational database management systems are establishing themselves as useful engineering tools. This is occurring at a time when engineers and architects are moving toward centralized and integrated databases of design information. In such a database, information is directly and readily available to all members of the design team, allowing them to work concurrently on an accurate representation of a wide variety of engineering design data. This paper presents the use of a relational database to model building design data and shows that the relationships among topology, geometry, and attributes can be successfully modeled relationally. The feasibility of interaction between engineering applications programs and the database is also indicated. Although the paper concentrates on structural design data for buildings, the relational model can also be used to represent the data of other engineering design disciplines as well as the data for other structures, assemblies, systems, and processes

summary Of all the contributions of artificial intelligence (AI), expert systems show some of the most significant promise for engineering applications. Expert systems provide a framework for acquiring, representing, and using knowledge about a particular application's domain. The role of knowledge in engineering design merits closer attention so that AI- oriented computer-aided engineering (CAE) systems can be developed and maintained systematically. Because 'knowledge' in engineering applications is loosely defined, it is necessary to identify knowledge types and the correlations between them before widespread engineering design applications can be achieved. The types of domain knowledge; facts, procedures, judgments, and control; differ from the classes of that knowledge; creative, innovative, and routine. Feasible tasks for expert systems can be determined based on these types and classes of knowledge. Interpretive tasks require reasoning about a task in light of the knowledge available, while generative tasks create potential solutions to be tested against constraints. Only after classifying the domain by type and level can the engineer select an appropriate knowledge-engineering tool for the domain being considered. The critical features to be weighed after problem classification are knowledge representation techniques, control strategies, interface requirements, compatibility with traditional systems, and economic considerations. After considering all of these factors in the selection of the expert system tool, the engineer can then proceed with the acquisition of knowledge and the construction and the use of the expert system

title Extending Database Management Systems for Engineering Applications
source Computers in Mechanical Engineering (CIME). American Society of Mechanical Engineers, March, 1987. vol. 5: pp. 62-69
summary During the design of a manufactured component, large amounts of information pertaining to all aspects of the design must be stored, accessed, and operated upon. A database management system (DBMS), composed of a central repository of data and the associated software for controlling accesses to it and operations on it, provides one way to uniformly store, manage, and use this information. This paper presents a framework for an extension to relational database management systems that combines a set of engineering constraints with a database of engineering data items. The representation requires a database that is able to store all of the data normally associated with engineering design as well as the constraints imposed upon the engineering design process. A powerful and flexible constraint processing system is needed to adequately ensure that engineering data conforms to the limitations imposed upon it by the design process. Such a system must be capable of allowing constraints to be invoked at a variety of times, and provide numerous options for the user when violations are detected. This paper introduces a concept called structured constraints that integrates state- of-the-art advances in DBMSs and current research in engineering constraint processing to further enhance CAD system capabilities. It discusses the extensions to relational database theory that are needed to achieve such a constraint handling capability for mechanical engineering applications. The goal sought is a managed repository of data supporting interfaces to a wide variety of application programs and supporting processing capabilities for maintaining data integrity by incorporating engineering constraints. The Structured Constraint model is a general method for classifying semantic integrity constraints. It is based on the structure of the relational model and is therefore independent of any particular query language. In addition, it is a formalism that possesses conceptual clarity and generality which make it useful for representing and communicating arbitrary constraints. The key contribution of this formalism is its basis for a completely definable implementation of an engineering integrity system

title Virtual Museum: Towards a new typology of the museum in the future

summary Architecture is affected by the information technology, one must consider two conditions: that the physical spaces of architecture as we have always known it (enclosure, form and permanence) will without a doubt persevere, and that it will exist alongside the virtual architecture, surfacing in the digital domain of the internet. Museums are now being constructed, navigated, experienced, comprehended, and altered in their virtual states by countless people across global networks. This new architecture of liquidity, flux and mutability is predicated on technological advances and fuelled by basic human desire to probe the unknown. The path that both types of architecture, the real and the virtual, take will be one of convergence. VR seems to be the next logical step in the path laid by CAD, but it will have a more extensive impact, since it not only transforms the way architects design and visualize, but can also be integrated into the final product of architecture itself: such as museums. The main goal of this paper is to emphasize the new typology of museums of the future in which digital technologies support all kinds of museum activities such as gathering, preserving, researching, exhibiting, and educating. Also, to introduce digital technologies for the digital museum such as media and new human interface technologies for novel exhibition styles and data processing technologies for digital archiving of cultural or historical artifacts. The paper highlights the technology used in this new typology of museums; the virtual museum. It also discusses the advantages and the disadvantages of the virtual museum.

summary We are in the very early stages of a digital revolution whose direction we will not be certain of for sometime, much in the same way that Enlightenment-era architects, theologians, and thinkers did not quite comprehend the profound changes taking place in their own time. Today’s digital technologies are having profound effects on many different aspects of our contemporary understanding from the human genome to the mapping of the cosmos. Digital manipulations that use virtual-reality technologies form a major part of this revolution. As architects we are responding in a number of ways, by conceiving of entirely new geometric principles, new methodologies, and entirely novel approaches to representation beyond perspectival geometry.
