title Tangible Computing - Manufacturing of Intertwined Logics
source Fioravanti, A, Cursi, S, Elahmar, S, Gargaro, S, Loffreda, G, Novembri, G, Trento, A (eds.), ShoCK! - Sharing Computational Knowledge! - Proceedings of the 35th eCAADe Conference - Volume 2, Sapienza University of Rome, Rome, Italy, 20-22 September 2017, pp. 115-122
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.

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.

title Designing a Building envelope using parametric and algorithmic processes
source SIGRADI 2015 [Proceedings of the 19th Conference of the Iberoamerican Society of Digital Graphics - vol. 2 - ISBN: 978-85-8039-133-6] Florianópolis, SC, Brasil 23-27 November 2015, pp. 797-801.
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.

title Trambolho: Interface híbrida para negociaç?o espacial de grupos remotos [Trambolho: Hybrid interface for remote spatial negotiation]
source SIGraDi 2016 [Proceedings of the 20th Conference of the Iberoamerican Society of Digital Graphics - ISBN: 978-956-7051-86-1] Argentina, Buenos Aires 9 - 11 November 2016, pp.808-815
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.

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 This paper describes current research on the computational modeling of change phenomena in design. In particular it introduces a tutorial view of the moel of design situations (DS) as a methodological basis for experimentation with change processes at the individual and the collective levels of an agent society. Creativity in the DS model takes place within the situated interaction of individuals in a social environment transcending its conventional characterization as purely a cognitive process.

summary This paper explores some aspects of group divergence based on principles of design disciplines and social dissemination. Extensions to an elementary model are used to explore the fundamental relation between divergence and social influence mechanisms previously employed to explain group convergence. The possible role of a change agent is investigated supporting the notion that there is no need to invoke any extraordinary mechanism other than convergence to trigger social change.

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.

title Parametric Performative Systems: Designing a Bioclimatic Responsive Skin
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.

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.

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.

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.

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 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.

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’.

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.

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.

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.

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.

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.

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.

title Generating a scalar logic: producing the "it's a SMALL world" exhibition
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.

source International Journal of Architectural Computing vol. 2 - no. 1
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.

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.

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

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

title Simplified Steel Compression Member Design
source Dynamics of Structures ASCE Structures Congress Proceedings. 1987. American Society of Civil Engineers, vol. D: pp. 352-367. CADLINE has abstract only
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

title Spike : A Generic Design Standards Processing Expert System
source Southampton, UK: Computational Mechanics Publications, pp. 241-257. Also published in : Applications of Artificial Intelligence in Engineering International Conference Proceedings (2nd. : 1987 : Boston, MA.)
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. An implementation of this architecture is presented and described

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

title A Knowledge-Based Approach to Engineering Information Retrieval and Management
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

title A Structure-Based Model of Semantic Integrity Constraints for Relational Databases
source International Journal of Engineering with Computers. Springer-Verlag, Spring, 1987. vol. 2: pp. 31- 39
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

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.

title Shape-Sensitive Configurational Descriptions of Building Plans
source International Journal of Architectural Computing vol. 10 - no. 1, 33-52
summary While the traditional graph-theoretic techniques of space syntax are able to provide a rich description of the spatial configuration of buildings, they are not sufficiently shape sensitive. Therefore, techniques are proposed to describe building plans as configurations of spaces taking into consideration the elements of shape explicitly. First, the traditional space syntax techniques are applied to a more shape-sensitive partition of a plan in order to find out if these techniques would reveal any interesting shape property of the plan. Following this, a technique to characterize the spatial units of a plan is suggested taking into consideration how surfaces become visible from these units. Finally, a plan is described as the configuration of triangles defined by the vertices of the shape of the plan, and triangulation is used as a technique for a shape-sensitive description of spatial configuration.

summary CNC cutting machines have become essential tools for designers and architects enabling rapid prototyping, model-building and production of high quality components. Designers often cut from new materials, discarding the irregularly shaped remains. We introduce ProjecTables, a visual augmented reality system for interactive packing of model parts onto sheet materials. ProjecTables enables designers to (re)use scrap materials for CNC cutting that would have been previously thrown away, at the same time supporting aesthetic choices related to wood grain, avoiding surface blemishes, and other relevant material properties. We conducted evaluations of ProjecTables with design students from Aarhus School of Architecture, demonstrating that participants could quickly and easily place and orient model parts reducing material waste. Contextual interviews and ideation sessions led to a deeper understanding of current work practices and sustainability issues with CNC cutting-machines, and identified useful features for interactive packing to reduce waste while supporting aesthetic concerns for exhibition quality design projects.

summary The use of 3D printing in architectural research, education and practice has been almost exclusively destined to produce physical representations – models— of designed building. Recent advances in Additive Manufacturing (AM) have exponentially increased the mechanical properties of 3D printed parts, opening new opportunities for this technology to be directly applied to functional architectural components at an increasingly larger scale. Thus, this paper examines the design, structural and aesthetic implications, as well as the feasibility of advanced 3D printing technologies in the production of functional architectural components through the design and prototyping of a customized, non-regular spatial frame system.

summary In order to design adaptable systems, the requirements include flexible models to generate a range of alternative configurations, analytical engines to evaluate performance, and well-defined selection criteria to identify suitable options. In most cases, design processes driven by performance concentrate on environmental or structural parameters; fabrication often remains disconnected from the generative process. Nonetheless, as design-to-fabrication methods become more robust, it is possible to extend the digital process to introduce fabrication variables to the definition of the project. The main focus of the research presented in this paper is the development of a digital and material workflow that connects design, structural and climate-specific topics (such as sun lighting and water drainage) toward producing a range of efficient structural and spatial assemblies.A case study serves as the main support for this investigation. Miguel Fisac’s “bones” is a light-weight roof system developed during the 1960’s, which had a very well-calibrated structural, natural-lighting, drainage and construction performance, as well as a highly refined spatial output. The system, despite its intelligence, lacked the flexibility possible today: using digital technologies, it can adapt to a significantly wider range of applications. Using “bones” as a starting point, this research develops a design-to-fabrication workflow that attempts to move forward tools, material systems and processes to enable an adaptable tectonic system.This paper describes the background research, concept, form-finding, construction process, methodology, results and conclusions of the investigation.

summary The promise of robotic fabrication as an enabler for mass-customization in Architecture has been hindered by the intricate workflow required to go from parametric modelling to CNC fabrication. The lack of integration between highly-specialized proprietary software, normally required to operate the machines, and most of the design tools constitutes a major limitation. One way to tackle this constraint is by developing simple tools that directly link parametric modelling to robotic coding. Accordingly, “Fisac Variations” develops an uninterrupted digital workflow from form-generation to robotic fabrication. This innovative approach to Computer Aided Design and Manufacturing was tested by studying and reengineering a specific historic construction system -Miguel Fisac’s Bones System was used as a case study- and by enabling it to address problems of contemporary architectural agenda such as flexibility, variability and mass-customization. The proposed workflow threads form-finding, structural analysis, geometric definition, CNC code generation and digital fabrication within the same open-source computational environment. In this way, this innovative procedure aims to increase design freedom while ensuring fabrication feasibility. This paper describes background research, concept, form-finding, construction process, methodology, results and conclusions.

summary Why computers are not yet used in the early phases of architectural design? This question requires a closer examination of the sketching process itself. Looking it from the hermeneutical point of view, it becomes quite obvious that sketching really is and probably should remain the last fortress resisting the computerization of design. Sketching is an intimate dialogue between drawings and language. It is a dynamic and circular process of understanding. Also its intrinsic methods to search solutions cause wicked problems for computer programming. Nevertheless, computers could be used more for assisting sketching. Their proper role would be in validating tentative solutions.

summary Computational Fluid Dynamics (CFD) simulations are used to predict the fluid behavior and particle systems-in-action in three-dimensional space, allowing experts to evaluate a series of environmental decisions in designing buildings. Although computing power has increased in the past decade, detailed CFD simulations introduce time-delay that defeats the notion of real-time data visualization. A method that can bypass the time-consuming simulations and generate results comparable to detailed CFD simulations will allow such visualizations to be constructed. This paper discusses a pilot project that utilizes a Reinforcement Learning (RL) algorithm coupled with a simplified fluid dynamics equation to generate thermal performance data for real-time visualization.

summary Computational Fluid Dynamic (CFD) simulations are used to predict indoor thermal environments and assess their response to specific internal/external conditions. Although computing power has increased exponentially in the past decade, CFD simulations are time consuming and their prediction results cannot be used for real-time immersive visualization in buildings. A method that can bypass the time consuming simulations and generate .acceptable. results will allow such visualization to be constructed. This paper discusses a project that utilizes Artificial Neural Network (ANN) as a learning algorithm to predict post-processed CFD data to ensure rapid data visualization. The technique has been integrated with an immersive Augmented Reality (AR) system to visualize CFD results in buildings. ANN was also evaluated against a linear regression model. Both models were tested and validated with datasets to determine their degree of accuracy. Initial tests, conducted to evaluate the user.s experience of the system, indicated satisfactory results.

The design process is integrated with other variables such as: participative design, directed self-build and the integration of tangible and intangible aspects. Parametric modeling was used as a strategy to create an integrated process of design, production and assembly based on a code created in grasshopper. Once finished, the housing unit will be handed over to a rural family. This will allow for doing follow-up and evaluation.

summary Capitalism does play a decisive role in the planning and generation of countless generic typologies in the urban landscape to a certain extent. This also includes the planning and generation of housing models. As a result of conventional planning that is based on ‘entrepreneurship subdivision’, only similar housing model for a specific income group is sometimes offered. In the long term, this kind of development occupies massive land, which is not suitable for sustainable growth and creates social segregation. This paper suggests an alternative approach of ‘associative design’. Parametric design software is utilized to generate the housing diversity. It aims to construct a population of housing units that together form a new neigh­borhood model based on the land specificity that emphasizes its economic and ecological factors.

summary Time is central to architectural design, but to date has not been fully investigated through computational media. The works of Heidegger, Bergson, Virilio and Deleuze suggest that the study of the elusive concept of time has more to contribute to an understanding of the human condition than space. One can argue that contemporary society is being governed increasingly by temporal structures, as the space of the town square is replaced by time-based broadcasting and digital communications. This shift from space to time is commonly associated with the ideal of smoothing boundaries and developing seamless environments. Contrary to this supposition, we propose that the putative “collapse” of time and space exposes disjunction and disruption. We develop the notion of “distressed space” as part of a design strategy in the context of time-based media. We draw on examples from real-time 3D animation using the MAX/MSP/Jitter programming environment and discuss some of its implications for design.

title Implicit Learning and Tacit Knowledge: An Essay on the Cognitive Unconscious
source New York: Oxford University Press
summary In this new volume in the Oxford Psychology Series, the author presents a highly readable account of the cognitive unconscious, focusing in particular on the problem of implicit learning. Implicit learning is defined as the acquisition of knowledge that takes place independently of the conscious attempts to learn and largely in the absence of explicit knowledge about what was acquired. One of the core assumptions of this argument is that implicit learning is a fundamental, "root" process, one that lies at the very heart of the adaptive behavioral repertoire of every complex organism. The author's goals are to outline the essential features of implicit learning that have emerged from the many studies that have been carried out in a variety of experimental laboratories over the past several decades; to present the various alternative perspectives on this issue that have been proposed by other researchers and to try to accommodate these views with his own; to structure the literature so that it can be seen in the context of standard heuristics of evolutionary biology; to present the material within a functionalist approach and to try to show why the experimental data should be seen as entailing particular epistemological perspectives; and to present implicit processing as encompassing a general and ubiquitous set of operations that have wide currency and several possible applications. Chapter 1 begins with the core problem under consideration in this book, a characterization of "implicit learning" as it has come to be used in the literature. Reber puts this seemingly specialized topic into a general framework and suggests a theoretical model based on standard heuristics of evolutionary biology. In his account, Reber weaves a capsule history of interest in and work on the cognitive unconscious. Chapter 2 turns to a detailed overview of the experimental work on the acquisition of implicit knowledge, which currently is of great interest. Chapter 3 develops the evolutionary model within which one can see learning and cognition as richly intertwining issues and not as two distinct fields with one dominating the other. Finally, Chapter 4 explores a variety of entailments and speculations concerning implicit cognitive processes and their general role in the larger scope of human performance

source Technical Note no. 559, SRI International, Menlo Park
summary This paper describes the representation and navigation of large, multi-resolution, georeferenced datasets in VRML97. This requires resolving nontrivial issues such as how to represent deep level of detail hierarchies efficiently in VRML; how to model terrain using geographic coordinate systems instead of only VRML's Cartesian representation; how to model georeferenced coordinates to sub-meter accuracy with only single-precision floating point support; how to enable the integration of multiple terrain datasets for a region, as well as cultural features such as buildings and roads; how to navigate efficiently around a large, global terrain dataset; and finally, how to encode metadata describing the terrain. We present solutions to all of these problems. Consequently, we are able to visualize geographic data in the order of terabytes or more, from the globe down to millimeter resolution, and in real-time, using standard VRML97.

summary The graphic intention is a peculiarity of the architectural drawing. It is enough to compare the ground plan of an unifamiliar housing insulated of Le Corbusier with another of Mies van der Rohe to realise the diversity of graphic styles, but is important to take conscience of the complexity that carries to interpret the symbols that appear in those documents, because as architects we either realize plans that the instructions are described or measures to be able to execute the work and in other occations representations for his edition aimed to a especialized public.

For this reason, and because not always is arranged the best possible documentation, we consider that the majority of vectorisations they exist in the market don’t plenty satisfied our needs as teaching staff of graphic expression and CAD, althoug we can always be using the same systems of projection or codified representations, it is imposed a lot of times to interpret acording the context the different signs and graphic registers used.

We know experimental applications that go beyond, they even arrive to generate a 3D model from a lifted hand draw that represents three orthogonal projections of it, but it isn’t less certain that its utility is restricted to fields very specialised and the option that we propose, there is not knowledge at least to us that it exist; commercially speaking.

Our porpose has been to develope a symple metedology of vectorisation but adapted to the special idiosyncrasy of the needs of an architecture student that with frequency for his formation requires to generate with CAD models 2D and 3D of architectural projects from the information contented in magazines, and with them create several formas analysis.

The most important difference in the matter to other systems is the interactivity of the procedure that let personify the exit file, even the wide diversity of graphic registers that it exist in the entrance, being the user only once has to identify and interpret the signs to detect, and then the process is realized automatically to any plant of the building or equivalent projection.

summary A painting is always a potential form of collage. The discovery made by Braque and Picasso was already implied in the carefully-done executions of tapestries backgrounds and mural decorating of all the italian and flemish paintings which started to be produced since Giotto's, where the represented and the presented were mixed up. And also, in a more pedantic way, in a famous painting of Courbet "L'Atelier du Peintre, allegorie reelle" (1885). In this work, the artist is shown sitting in front of his work, grasping a brush with his right hand while holding a palette, which is at the centre of the composition, in his left hand. There are some figures surrounding the master, some nearer, others further away; in the corners of the atelier one can still see silhouettes which we don't really know whether they belong to real characters or to painted ones on the master's canvases. This ambiguity brings us back to the foreground, to this central palette where the colours, distributed in heaps are, simultaneously, concretion and representation, real matter and figurative matter.

summary Nous qui devons enseigner à nos élèves les techniques du dessin traditionnel avons trop souvent recours à des recettes et normes mnémotechniques venues des ateliers et studios d'art traditionnels. De telles stratégies, souvent personnelles et intransférables, s'appuyant sur de longues heures de pratique, sont difficilement assimilables pour des élèves qui ne disposent pas de tant de temps pour s'entraîner, ni d'une telle expérience perceptive; dans le meilleur des cas, il en résulte un dessin stéréotypé ou, s'il est brillant, c'est que l'élève savait déjà dessiner. Comme nous considérons que le dessin traditionnel et le CAD sont les deux outils fondamentaux qui permettent à tout architecte d'exprimer ses idées, il nous a semblé opportun de chercher les points communs entre ces deux disciplines. Dans un discours illustré de dessins d'auteurs divers, nous essaierons de démontrer comment, si nous utilisons exactement les mêmes critères que ceux qui régissent un ordinateur dans l'interprétation de ce qu'il voit, le résultat de la représentation est pleinement expressif et efficace. Si nous sommes capables de rationaliser cette méthodologie et de la transmettre à nos élèves, nous aurons répondu à notre double objectif: leur enseigner à dessiner par des techniques traditionnelles, dûment rationalisées et comprendre un peu mieux le fonctionnement des ordinateurs.

summary Sustainable architecture is high-tech, energy and resource conserving architecture that sustains and increases the human and natural carrying capacity of the host environment. This paper presents a computer assisted design process to teach sustainable architectural design.

The energy performance of a base case building in each of four climates and cultures is presented. The climates are: Phoenix (hotdry), Minneapolis (cold-dry), Boston (cold-humid), and New Orleans ( hot- humid). Keeping the host climate, site, building size and function constant: but varying materials, shape and design concepts, each base case is iterated through a series of computer assisted re-designs to transform each base case building into an architecture representative of its regional climate and culture.

Traditional technologies and concepts produce traditional regional architecture. New technologies and concepts produce forms expressive of an emerging high-tech, high-touch, low energy society.

The paper presents computer generated work by the author and his students. It also presents an interim evaluation of the successes and difficulties of conducting a 'paper free' design studio.

title Computational Situated Learning in Designing - Application to Architectural Shape Semantics
source The University of Sydney, Faculty of Architecture
summary Learning the situatedness (applicability conditions), of design knowledge recognised from design compositions is the central tenet of the research presented in this thesis. This thesis develops and implements a computational system of situated learning and investigates its utility in designing. Situated learning is based on the concept that "knowledge is contextually situated and is fundamentally influenced by its situation". In this sense learning is tuned to the situations within which "what you do when you do matters". Designing cannot be predicted and the results of designing are not based on actions independent of what is being designed or independent of when, where and how it was designed. Designers' actions are situation dependent (situated), such that designers work actively with the design environment within the specific conditions of the situation where neither the goal state nor the solution space is completely predetermined. In designing, design solutions are fluid and emergent entities generated by dynamic and situated activities instead of fixed design plans. Since it is not possible in advance to know what knowledge to use in relation to any situation we need to learn knowledge in relation to its situation, i.e. learn the applicability conditions of knowledge. This leads towards the notion of the situation as having the potential role of guiding the use of knowledge.

Situated Learning in Designing (SLiDe) is developed and implemented within the domain of architectural shape composition (in the form of floor plans), to construct the situatedness of shape semantics. An architectural shape semantic is a set of characteristics with a semantic meaning based on a particular view of a shape such as reflection symmetry, adjacency, rotation and linearity. Each shape semantic has preconditions without which it cannot be recognised. Such preconditions indicate nothing about the situation within which this shape semantic was recognised. The situatedness or the applicability conditions of a shape semantic is viewed as, the interdependent relationships between this shape semantic as the design knowledge in focus, and other shape semantics across the observations of a design composition. While designing, various shape semantics and relationships among them emerge in different representations of a design composition. Multiple representations of a design composition by re-interpretation have been proposed to serve as a platform for SLiDe. Multiple representations provide the opportunity for different shape semantics and relationships among them to be found from a single design composition. This is important if these relationships are to be used later because it is not known in advance which of the possible relationships could be constructed are likely to be useful. Hence, multiple representations provide a platform for different situations to be encountered. A symbolic representation of shape and shape semantics is used in which the infinite maximal lines form the representative primitives of the shape.

SLiDe is concerned with learning the applicability conditions (situatedness), of shape semantics locating them in relation to situations within which they were recognised (situation dependent), and updating the situatedness of shape semantics in response to new observations of the design composition. SLiDe consists of three primary modules: Generator, Recogniser and Incremental Situator. The Generator is used by the designer to develop a set of multiple representations of a design composition. This set of representations forms the initial design environment of SLiDe. The Recogniser detects shape semantics in each representation and produces a set of observations, each of which is comprised of a group of shape semantics recognised at each corresponding representation. The Incremental Situator module consists of two sub-modules, Situator and Restructuring Situator, and utilises an unsupervised incremental clustering mechanism not affected by concept drift. The Situator module locates recognised shape semantics in relation to their situations by finding regularities of relationships among them across observations of a design composition and clustering them into situational categories organised in a hierarchical tree structure. Such relationships change over time due to the changes taken place in the design environment whenever further representations are developed using the Generator module and new observations are constructed by the Recogniser module. The Restructuring Situator module updates previously learned situational categories and restructures the hierarchical tree accordingly in response to new observations.

Learning the situatedness shape semantics may play a crucial role in designing if designers pursue further some of these shape semantics. This thesis illustrates an approach in which SLiDe can be utilised in designing to explore the shapes in a design composition in various ways; bring designers! attention to potentially hidden features and shape semantics of their designs; and maintain the integrity of the design composition by using the situatedness of shape semantics. The thesis concludes by outlining future directions for this research to learn and update the situatedness of design knowledge within the context of use; considering the role of functional knowledge while learning the situatedness of design knowledge; and developing an autonomous situated agent-based designing system.

summary Architects and designers are normally interested in situations where differences make a difference. This paper presents the results of the developed system of intelligent design agents that supports design exploration and creativity within the domain of architectural shapes. Creativity in architectural design compositions can be viewed as an emergence of new forms and shapes or relationships between forms and shapes from which new concepts can be discovered.

source Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 133-140
summary 3D Virtual Environments (VEs) have the potential to reach beyond the limitations of CAD systems and can be utilised as design tools for architecture. This paper introduces a framework of semantic-based Virtual Design Environment(VDE) that aims to provides designers of VEs with virtual observers of designers’ actions (intelligent design agents and collaborative assistant agent) to investigate the current design and respond to these actions when the need arises. The paper presents the development of a representation structure of building-objects and their relationships to be used in constructing building designs in the 3D VDE and outlines sets of design semantics to be incorporated within the VDE.

summary Designers recognise or make sense of objects in the context "situations" of other things. Design cannot be predicted and you have to be “at a particular set of states” in order to decide what to do. The inability to determine a priori all design states implies that any design process cannot be pre-planned and design actions cannot be pre-defined. Situated learning is based on the notion that knowledge is contextually situated and is fundamentally influenced by the context in which it is used. We propose a situated learning approach in the domain of architectural shapes design. This paper elaborates the concept of situated learning and demonstrates what it produces in the domain of shape semantics.

title Situatedness: A New Dimension for Learning Systems in Design
source Architectural Computing from Turing to 2000 [eCAADe Conference Proceedings / ISBN 0-9523687-5-7] Liverpool (UK) 15-17 September 1999, pp. 252-261
summary In this paper we adopt the approach that designing is a series of situated acts, ie designing cannot be pre-planned to completion. This is based on ideas from situated cognition theory that claims that what people perceive, how they conceive and what they do develop together and are adapted to the environment. For a system to be useful for human designers it must have the ability to associate what is learned to its environment. In order for a system to do that such a system must be able to acquire knowledge of the environment that a design constructs. Therefore, acknowledging the notion of situatedness is of importance to provide a system with such capability and add on a new dimension to existing learning systems in design. We will call such a learning system within the design domain a Situated Learning Design System (SLDS). A SLDS should be able to create its own situational categories from its perceptual experiences and modify them if encountered again to link the learned knowledge to its corresponding situation. We have chosen architectural shapes as the vehicle to demonstrate our ideas and used multiple representations to build a platform for a SLDS to learn from. In this paper the notion of situatedness and its role in both designing and learning is discussed. The overall architecture of a SLDS is introduced and how the potential outcome of such a system will support human designers while designing is discussed.

The approach is implemented in SLiDe (Situated Learning in Designing) and integrated as SLiDe-CAAD, to provide interactive support in designing exemplified within the composition of architectural shapes. SLiDe-CAAD is proposed to assist in maintaining the integrity of shape semantics or desired design concepts of interest in the design composition.

summary The advancements in digital design and communications are reshaping the economics of architecture and design practices. Designing with computers is based on establishing a fruitful dialogue between the designer and the tool. The "digital imperative" to switch from analogue to digital mode have already begun to manifest itself at the schools of design and architecture in the form of the paperless Design Computing Studio (DCS). This paper describes and reflects on the designing and teaching approach implemented in a paperless DCS within the domain of architectural design. The paper presents the implementation of this approach, on the first year students of the new degree of Design Computing at the University of Sydney and analyses the students’ design learning experience in the DCS.

summary Concept invention refers to the act of discovering new concepts for the first time. Concept invention may require a new interpretation that motivates new mappings of the situation prior to the discovery of a new concept. This paper is concerned with developing intelligent design agents that would be capable of inventing creative concepts of design forms, shapes and compositions while involved in the design process. A new approach of exploiting the old notion of "displacement of concepts" with regard to concept invention in designing in the form of mobile design agents is adopted and utilised in developing the structure of intelligent mobile agentbased system.

summary This paper addresses the utilization of Data Mining as an advanced technique of information technologies to investigate and identify the patterns of architectural features of contemporary architecture in Saudi Arabia in two suggested building types: houses and commercial office buildings. Such patterns will help in developing a model of patterns of architectural features that can be utilized to augment the architectural context of Saudi Arabia. The paper presents a constructed framework that provides a comprehensive analysis of recognition criteria for identifying each architectural feature of the nominated set of nine features. These architectural features include: spatial relationships, space allocation, circulation, building form, façade treatment, building structure, external finishes, environmental aspects, and cultural features. The recognition criteria for these architectural features are expressed in the attribute-value format. Such criteria are extracted for houses and commercial office buildings specifically within the context of Saudi contemporary architecture based on extensive case analysis that represents the diversity of architectural designs of houses and commercial office buildings. The paper also, introduces a process model of applying Data Mining for investigating patterns of contemporary architecture.

summary This paper presents some of the results of my work in the area of architectural education and color application. "Constructive Learning" techniques are the framework within which a course in color theory and application has been developed for architectural students and professionals. Constructive learning theory designates three main learning phases: introductory, advanced and experienced; each of which has a unique set of requirements that must be addressed by those seeking to teach or develop meaningful tools for a given task. The introductory level is represented by those who posses little if any prior skills or knowledge in the subject area. Here it is advantageous to carefully guide the knowledge acquisition process in order to help build a knowledge foundation upon which a personalized learning process can take place. Advanced students are those that are ready, through a more focused, context related approach, to expand their capabilities. Finally, experienced learners can be defined as those capable of critically applying and innovatively using the knowledge, skills and tools that they have obtained through the introductory and advanced phases of the learning process. Because computers introduce the issue of color at a much earlier stage of design than might previously have been the case, a new set of skills and tools are needed. The proposed course seeks to define an appropriate learning methodology for designers that can provide them with not only knowledge of the subject area being covered, but also skills with which to approach it.

summary This article describes VRAM, short for Virtual Reality Aided Modeler. VRAM is a conceptual design tool supported by Virtual Reality technology and an ongoing testbed for theory and methodology in the field of three dimensional user interfaces (3DUIs). The outcomes from the project should consist of an intuitive and comprehensive immersive surface modeler, next to a set of taxonomies and guidelines for the development of 3DUIs. Based on a modular structure, VRAMs program architecture allows the easy extension of functionality. The application consists of the seamless integration of four main functionality modules, namely system control, viewing & browsing, editing and modeling. Based on the premise of portability, the software environment runs on both SGI Irix and MS Windows NT platforms. To be relatively independent in developing 3DUI techniques, the VRAM environment supports a multiplicity of input and output devices. Due to the focus on immersive modeling, tracking devices, head mounted displays and stereoprojection devices are the main I/O channels. In this article, we will primary focus on the functionality of the virtual modeller.

summary The author describes a novel way for generating line drawings of 3-dimensional objects and describes a computer program that he used in plotting such drawings. Instead of being confined by the rules of linear perspective, which governs retinal and photographic images, he employs a more general mathematical model that provides a family of perspectives. Each member of the family is designated individually by a numerical value (between 0 and 1) for its index i. The lowest value, i=0, leads to the linear equation that applies to linear perspective; application of the highest value, i=1, results in axonometric projection. Sometimes linear perspective leads to a drawing or to a photographic image that seems grossly distorted in comparison with what one perceives in looking at an object. The author's method, employed with fractional values for i and with the same viewpoint, may be used to produce more acceptable drawings

summary The digital animation provides the exploration of virtual expression making it possible to undertand complexities in architectural design. The purpose of this research was to verify user perception of the architectonic project through computerized animation. An experiment was developed to identify the user architectonic perception when watching the project animation compared to the reality of the accomplished kitchen project. Two kinds of digital animation were experimented: a simplified animation (using standard shading and render preview) and a realistic animation (using scanline resource for digital scenes rendering). It was verified that the simplified digital animation presents satisfactory cost-benefit relation in order to obtain design understanding for both, user and designer. Based on this experiment, directives were specified for the creation and aplication of a questionary together with design digital animation in order to verify architectonic program requeriments, for increased design compreehation.

We envision thiseffort expanding to facilitate collaboration and process archival for distributed design and manufacturing teams.CAD knowledge-bases are vital to engineers, who search through vast amounts of corporate legacy data and navigate on-line catalogs to retrieve precisely the rightcomponents for assembly into new products. This research attempts to begin addressing the critical need for improved computational methods for reasoning about complexgeometric and engineering information. In particular, we focus on archival and reuse of design and manufacturing data for mechatronic systems. This paper presents adescription of the research problems, an overview of the initial architecture of the testbed and a description of some of our preliminary results on conceptual design anddesign retrieval.

summary Continuing with our research in free-form surface models, this paper proposes a methodology that analyzes the basic entities of architectural forms to generate virtual models with a high range of accuracy. We use NURBS technology because this kind of entities has very large characteristics of generation, transformation and modification in front of mesh’s entities.

summary This paper explains the three-dimensional representation procedure of one fragment of Mil· house elevation designed by the architect Antoni GaudÌ. The generation process of an architectonic virtual model constituted by free form surfaces like this, represents a paradigm of high level difficulty in CAD modeling. The main objective of our research has been not only construct a model that shows the complex form of its architecture, but also verify the performance of the different tools supported by computer aided design programs in the management of surface modeling.We obtained an accurate information of the real surface elevation with a photogrammetric survey using contour lines. The transformation of this kind of data in a three-dimensional model was not immediately Thus, we have had study different ways to generate the three-dimensional model solution. The process began with the construction of different surface models supported by analytic functions, but the obtained surfaces made with this system were deficient and not too much satisfactory. That's why, we use a polyhedron mesh surface method in order to improve these results.in spite of this methodology reductive performance, (compared with analytic function systems), the obtained surface demonstrated that this technique was the best way to satisfy the requirement of a free form surface previously established as we want to construct. From this point the principal problem was generate a surface defined by two-dimensional data, (contour lines), applying an automatic process sufficiently fast to compete with the analytic function systems.To satisfy the demand was necessary make complementary software to improve the process and allow more fluidity to resolve this typology of surfaces. We achieved this phase thanks to Joan Miquel Quilez collaboration and the constant dedication in the elaboration of complementary software to computer aided design. Finally, the introduction of render systems with lights, shadows, textures and reflected images, allowed show the studied elevation area of Mil· house with more accuracy. Thus, the limits and contours of the finally surface were more evident and help us to known the properties of a non- materialized free form surface successfully.

summary Pittsburgh, PA: Engineering Design Research Center, CMU, 1988. EDRC 05-22-88. This paper presents a new system for computer-aided mechanical design known as CASE, which stands for Computer- Aided Simultaneous Engineering. CASE was developed to support mechanical design at the project level, and serve as a means of integrating into the design process concerns from other parts of the lifecycle of a product. CASE is composed of an integrated framework of synthesis, analysis, and translation programs, and is designed to serve as a testbed for research in representation, problem-solving, and systems integration for computer-aided mechanical design. A prototype version of CASE has been applied to the domain of window regulator design, and is capable of automatically synthesizing regulators to meet a set of specifications and performing tolerance and stress analysis on developing designs

First generation expert systems suffer from two major problems: they are brittle and their development is a long, effortful process. Few successful expert systems for real world problems have been demonstrated. In this paper, learning, the key to intelligent behavior and expertise, is described as the answer to both expert systems deficiencies. Machine learning techniques are described, with their applicability to expert systems. A framework to organize machine learning techniques is provided.

summary Computational models of solid objects are potentially useful in a variety of scientific and engineering fields, and in particular in the field of design and manufacturing automation for the mechanical industries. In recent years a multitude of modelling systems have been implemented both by research laboratories and commercial vendors, but little attention has been paid to the fundamental theoretical issues in geometric modelling. This has led to severe difficulties in assessing current and proposed systems, and in distinguishing essential capabilities and limitations from user conveniences and efficiency considerations. This paper seeks a sharp mathematical characterization of 'rigid solids' in a manner that is suitable for studies in design and production automation. It draws heavily on established results in modern geometry and topology. Relevant results scattered throughout the mathematical literature are placed in a coherent framework and presented in a form accessible to engineers and computer scientists. A companion paper is devoted to a discussion of representational issues in the context set forth by this paper

summary This paper is about the merging of two software applications that allows building decision makers to consider code compliance and to use performance simulation tools from the early, schematic phases of building design. By making the capabilities of a code compliance tool available at the early schematic phases of building design, the hope and expectation is that users will use this software to address the mandatory code compliance issues and thus have an opportunity to address other performance issues as well.

summary The photorealistic visualisation of lighting-scenarios with the help of virtual 3d city models is gaining importance as a tool, helping to make decisions in the process of planning. This form of presentation makes sense to every spectator very quickly and in a definite way, thus it makes collaboration easy especially in interdisciplinary planning teams. Moreover the light-planner has the possibility to check his design in a virtual surrounding and therefore gain additional reliability for his planning. The displayed, exemplary, workflow and the techniques belonging to it, allow to show situations during the course of planning and to present the current state of planning realistically. Hence the quality of planning can be enduringly improved, through experimental use of new materials and ideas. Moreover alternative planning that does not show the right results can be eliminated very early in planning process, with not need for special investments to do so.

title Cultural formations in text-based virtual realities
source University of Melbourne
summary Beginning with an understanding of virtual reality as an imaginative experience and thus a cultural construct rather than a technical construction, this thesis discusses cultural and social issues raised by interaction on 'MUDs', which are text-based virtual reality systems run on the international computer network known as the Internet. MUD usage forces users to deconstruct many of the cultural tools and understandings that form the basis of more conventional systems of interaction. Unable to rely on physical cues as a channel of meaning, users of MUDs have developed ways of substituting for or by-passing them, resulting in novel methods of textualising the non- verbal. The nature of the body and sexuality are problematised in these virtual environments, since the physical is never fixed and gender is a self-selected attribute. In coming to terms with these aspects of virtual interaction, new systems of significance have been developed by users, along with methods of enforcing that cultural hegemony through power structures dependent upon manipulation of the virtual environment. These new systems of meaning and social control define those who use MUDs as constituting a distinct cultural group.

summary When working on urban planning projects there are usually multiple aspects to consider. Often these aspects are contradictory and it is not possible to choose one over the other; instead, they each need to be fulfilled as well as possible. Planners typically draw on past experience when subjectively prioritising which aspects to consider with which degree of importance for their planning concepts. This practice, although understandable, places power and authority in the hands of people who have varying degrees of expertise, which means that the best possible solution is not always found, because it is either not sought or the problem is regarded as being too complex for human capabilities. To improve this situation, the project presented here shows the potential of multi-criteria optimisation algorithms using the example of a new housing layout for an urban block. In addition it is shown, how Self-Organizing-Maps can be used to visualise multi-dimensional solution spaces in an easy analysable and comprehensible form.

summary The paper discusses an interdisciplinary exchange between parametric design and acoustic simulation. It reviews a strategic development of temporary dynamic structures that can be manipulated by intersecting variations of formation in generative architecture with acoustic simulation. The research investigates drivers that interface knowledge between parametric design, structural engineering and fabrication, interaction design and acoustics, and theatre and performance. It reviews the simulation of a temporary theatre installation into an existent industrial hall, whereby different formation of a modular structure are explored, and the acoustic effects of this installation are evaluated in relation to an enhancement of the audiences spatial and acoustic experience. The research goes beyond the morphological, aesthetic or structural values that have become key aspects of contemporary digital architecture, and relates them to the field of auralisation (forecasting acoustic behaviour). In that manner, the simulation and analysis of a future (material, spatial) objects is developed through the communication of an interdisciplinary team, thus exploring synergetic qualities of the physical and the digital.

summary Randomness can introduce degrees of variation as part of a highly controlled design process, which can be of particular significance in the context of acoustic performance in architecture. This paper presents research into robotic fabrication of surfaces with acoustic micro-patterns that can change the acoustic response of space. It explores the design affordances for acoustically efficient 1:10 scale model prototypes, from parametric modeling to scale model production to physical evaluation. Acoustic reflective properties of surface patterns are investigated for scattering coefficients, in order to derive statistical data on acoustic properties of these surfaces, and to deduce design rules. The robotic subtractive process particularly invests variations and disturbances to originally coded fabrication sequences that lead to different pattern outcomes. Changes to protocols and workflows change the equations of design through shuffling of multiple criteria: from multiple sequences in a production process to intuitive impacts of the designer on a preset tooling and workpath; from computational design code to acoustic effect.

summary This paper presents empirical research into the acoustic performance of randomized robotically fabricated patterns. Randomness is introduced as degrees of variations in code, both supported by quasi-predictable variations in a computational process, and the select changes through multiple variables in precise robotic fabrication that extend the spectrum for manufacturing diversity in micro-geometries that can change the acoustic response of space. Through physical acoustic testing of scale model 1:10 prototypes in a scale model reverberant box, and consecutive re-modelling of sound discs based on root mean square and depth comparison, a tendency for acoustic behaviours both for scattering and absorption could be demonstrated that relates low spatial frequency magnitude of surface modulation closely to scattering coefficient in a limited case study of six samples. As a result, the study presents a mathematical model that links form and material for sound scattering.

summary This paper addresses the acoustic performance of complex curved surface geometries that are commonly known to pose problems of sound concentration, thus affecting speech intelligibility and audience experience in spaces of temporal arts performance. It reviews an open system of design research in which parametric design process, structural analysis and acoustic analysis are deployed to improve the sound of ellipsoidal structures in relation to sound source and audience positions, by adapting the height, dimension and centre point of a dome structure, consequently improving the acoustic behaviour of the performance space. The paper discusses an iterative design, analysis and optimization processes, in which a number of generative form variations were developed in Grasshopper, and reworked in McNeel Rhino, tested in engineering software (Strand7), and evaluated in acoustic simulation (ODEON). This allowed an interdisciplinary team to develop, test and evolve a design proposal that shows one solution for avoiding sound concentration and consequently improving acoustic performance in complex intersecting and curved geometries of a multifunctional building.

summary A variety of distributed algorithms are presented and proven correct in this book. A (Petri net based) technique to model and to analyze distributed algorithms is coincidently presented. This technique focusses on local states, independent actions, and synchronization of distributed threads of control. This book's scope is modest, as it sticks to a choice of small and medium size distributed algorithms. Compositionality, stepwise refinement, interface specification, abstraction, etc., are not covered. Nevertheless, this book's claims are ambitious: Just as PASCAL-like programming structures and Hoare-style proof techniques appear optimal for a wide class of sequential algorithms, this book's formalism is suggested to be optimal for a wide class of distributed algorithms. Particular preliminary knowledge is not assumed in this text, besides basics in formal concepts and a general intuitive understanding of computer science. The text provides a basis for university courses and can help the practitioner to design distributed algorithms. The hurried reader may just study the pictures.

summary This project . presented in the form of an artistic installation . focuses on the social, economic and political causes of hunger, its challenges, consequences and possible solutions. Those issues are discussed through the views, ideas and perceptions of 100 people we interviewed. People who live in diverse economic contexts, who face different challenges, eat different types of food . or who don.t have anything to eat. They discuss their different needs, desires, requisites and willingness. They talk about their awareness (or their lack of knowledge) of the dramatic figures of hunger, they share their thoughts and ideas on how we can reduce or eliminate hunger, on what are they doing for that to happen, and on what they believe can be done. We believe that a more realistic framework of understanding of hunger enables people to make real choices, choices that can contribute to ending this spreading human suffering.

summary The production of concrete structure components is often a backbreaking process due to the inconvenient and time-consuming process of producing the formwork. Depending on the geometry, this can be a very time-consuming activity. A trial will be made to solve these problems within the manufacturing process using adapted binder jetting technology. First of all, the research will deal with the behavior of concrete as well as the bond between the cement paste and the aggregate. Various additives and grain sizes will be determined to find an appropriate result. On the other hand, different spray and drop systems will be analyzed to compare the new method and the common binder jetting setup. After fabricating some geometrical shapes manually the study is going to be continued using computer-aided manufacturing.

summary As technology affine urban landscape architects, working in Asian mega cities, we conduct research on urbanity beyond prime premises and nice neighbourhoods with maximum tourist potential. We roam through crowded and super narrow, widely informal city layouts, where we apply our digital fieldwork equipment and conduct design work. In these places we test low cost cameras and camera drones, tools that had been developed as documentation equipment for outdoor sportspersons respectively playthings for all the world. Technically limited, if not insufficient and physically labile, these basic tools help us to experiment in the field without problematic loss risks and without scaring people on site. In this paper, we describe a method of on-site data and image gathering, which allows the processing of 3D models of labyrinthine informal city spaces. The result of our study is a three-dimensional puzzle of sufficient precision, making a widely inaccessible and undocumented piece of city terrain visible, understandable and designable.

Great part of the current examples of memorization structures applications in spacialities design are related to experimental virtual environments, mainly tied with the artistic production and/or the studies of design of user-computer interfaces. Our research suggests a new look at this subject, considering to investigate, beyond the virtual spacialities, applications in the concrete and hybrid spaces. In this article we propose to argue the subject from two metaphors related to the theater: the metaphor proposal for Brenda Laurel in Computer as a Theatre and the boarding of Giulio Camilo [ 1480-1544 ] in its Theater of the Memory.

summary The paper is dedicated to conceptual design stage in AEC projects since this stage defines most of further design and even construction. Conceptual design is less automated and more human depended part of a complex design process. It is reasonable to link modern construction design software with ideas generation techniques in order to enhance and automate design creativity and effectiveness. In the article we propose computer-aided automation of searching for new conceptual ideas and nontrivial solutions during early design stage in AEC projects using such TRIZ tools as Function Modelling and Trimming in BIM technology. For description of our approach we consider framed buildings.

summary This paper describes a conceptual framework for modeling activity interactions between household heads in conducting out-of-home maintenance activities. It is comprised of several steps; generation of household activities, task allocation of household activities, trip-chaining choices, resource allocation and mode choice. The models are specified for different household types: worker and non-worker households, with or without children. The purpose of this paper is to introduce the modeling framework for household travel activity decision making processes so that it can capture interactions between household heads.

summary In Belgium there are two possibilities to study architecture, it can either be done at a higher institute or academy, or at a university. At the higher schools of architecture the computer equipment has just been installed during the last years, and teaching of CAAD is not yet integrated. There exists only a general computer course. At the universities hardware has been available since several years, and software has been developed. The following programs have been implemented in Liege : LPB1, LPB2, LPB3, LPB4 (energy analysis), FEASIBILITY (to obtain acceptable values for the main global parameters of a design), VOLUME, (3D modelling for building modelisation and manipulation) and TYPOLOGIE (for the determination of classes for the energetic behaviour of residential buildings).

title Constructive Solid Geometry
source November, 1977. [3] 36 p. : ill. includes bibliography: p. 31-33
summary The term 'constructive solid geometry' denotes a class of schemes for describing solid objects as compositions (usually 'additions' and 'subtractions') of primitive solid 'building blocks.' The notion of adding and subtracting solids has been used by mechanical designers and others for generations, but attempts to embody it in computer-based modelling systems have been hindered by the absence of a firm mathematical foundation. This paper provides such a foundation by drawing on established results in modern axiomatic geometry and point set topology. The paper also initiates a broader discussion, to be continued in subsequent papers, of three seminal topics: mathematical modelling of solids, representation of solids, and calculation of geometrical properties of solids

title Representations for Rigid Solids : Theory, Methods, and Systems
source Computing Surveys December, 1980. vol. 12: pp. 437-464 : ill. includes bibliography.
summary Computer-based systems for modeling the geometry of rigid solid objects are becoming increasingly important in mechanical and civil engineering, architecture, computer graphics, computer vision, and other fields that deal with spatial phenomena. At the heart of such systems are symbol structures (representations) designating 'abstract solids' (subsets of Euclidean space) that model physical solids. Representations are the sources of data for procedures which compute useful properties of objects. The variety and uses of systems embodying representations of solids are growing rapidly, but so are the difficulties in assessing current designs, specifying the characteristics that future systems should exhibit, and designing systems to meet such specifications. This paper resolves many of these difficulties by providing a coherent view, based on sound theoretical principles, of what is presently known about the representation of solids. The paper is divided into three parts. The first introduces a simple mathematical framework for characterizing certain important aspects of representations, for example, their semantic (geometric) integrity. The second part uses the framework to describe and compare all of the major known schemes for representing solids. The third part briefly surveys extant geometric modeling systems and then applies the concepts developed in the paper to the high-level design of a multiple- representation geometric modeling system which exhibits a level of reliability and versatility superior to that of systems currently used in industrial computer-aided design and manufacturing

title Pianos Not Stereos: Creating Computational Construction Kits
source Interactions, 3 (6)
summary The stereo has many attractions: it is easier to play and it provides immediate access to a wide range of music. But "ease of use" should not be the only criterion. Playing the piano can be a much richer experience. By learning to play the piano, you can become a creator (not just a consumer) of music, expressing yourself musically in ever-more complex ways. As a result, you can develop a much deeper relationship with (and deeper understanding of) music. So too with computers. In the field of educational technology, there has been too much emphasis on the equivalent of stereos and CDs, and not enough emphasis on computational pianos. In our research group at the MIT Media Lab, we are developing a new generation of "computational construction kits" that, like pianos, enable people to express themselves in ever-more complex ways, deepening their relationships with new domains of knowledge.

summary The paper will discuss two projects which explore the territory of discrete or digital material organisations in an architectural context. Taking inspiration from the field of Digital Materials, this paper presents an approach to architectural design which is fundamentally "digital" - not just in the process but also in its physical organisation. The use of discrete and digital materials in architecture is argued for from both an architectonic point of view, as well as from efficiencies related to automation of construction. Experiments with robotic assembly are caught between on the one hand the desire to increase speed, and on the other hand increased complexity. This paper argues that robotic assembly on the scale of architecture is only feasible and scalable in the context of digital materials and discrete computation, which has a limited set of connectivity problems. The two projects are a first attempt to translate the concept of Digital Materials to the domain of architecture. The result is an architecture which is digital in its physical organisation. It demonstrates how differentiated, complex and heterogeneous spaces can be achieved with just serialised, discrete elements.

summary The research presented in this paper is part of a larger, emerging body of research into large-scale 3D printing. The research attempts to develop a computational design method specifically for large-scale 3D printing of architecture. Influenced by the concept of Digital Materials, this research is situated within a critical discussion of what fundamentally constitutes a digital object and process. This requires a holistic understanding, taking into account both computational design and fabrication. The intrinsic constraints of the fabrication process are used as opportunities and generative drivers in the design process. The paper argues that a design method specifically for 3D printing should revolve around the question of how to organize toolpaths for the continuous addition or layering of material. Two case-study projects advance discrete methods as efficient ways to compute a continuous printing process. In contrast to continuous models, discrete models allow users to serialize problems and errors in toolpaths. This allows a local optimization of the structure, avoiding the use of global, computationally expensive, problem-solving algorithms. Both projects make use of a voxel-based approach, where a design is generated directly from the combination of thousands of serialized toolpath fragments. The understanding that serially repeated elements can be assembled into highly complex and heterogeneous structures has implications stretching beyond 3D printing. This combinatorial approach for example also becomes highly valuable for construction systems based on modularity and prefabrication.

title Design As Argumentation and Power-Acting - Theory and Methods
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary The process of design is seen as the generation, transformation and communication of knowledge in the brains of the professional designers and other persons and groups, who are interested in or concerned by the design output and who would or should participate in the design process. Only if it is known how these kinds of information and communication processes work, computer support is possible. Design thinking follows a microstructural scheme. A steady change of the understan-ding of the problem also changes the sight of the solution and also changes the need for knowled-ge contributing to the solution. In all stages of the design process alternatives or alternative ways of action are generated. The participants communicate about questions feasibility, the distribution of advantages and disadvantages, expected consequences, and other possibilities. They exchange positions and arguments, upon which finally they base their weighting of aspects and their personal judgement. The process of argumentation and evaluation is considered, it can be formalized and supported by formal methods. The decision about a design alternative by different people is not only based on explicit argumentation and/or formal evaluation procedures, but also on the use of power. Different means of power are stated. Some decision making procedures which control the misuse of power, are discussed.

summary "Unpersonified displacements" deals with the question of virtualization of individuals. We argue that virtual worlds are a combination of both physical and electronic environments that focus especially on processes and actions, rather than on objects and perceptual signs. Our piece is more contemplative than interactive. Indeed, it has been designed to run indefinitely. Simple shapes with simple behavior may provoke unlimited semiosis in persons. We believe this fact is because we identify ourselves within the process of movement, not with the media that conveys the action.

summary The awareness about the gap between general design theory and design practice is increasing. Design practice is not really served with the results of current design theory. To build a bridge between theory and practice, design researchers should know what is really going on in practice. To explore design practice and to find the most important characteristics of design situations, I have chosen an empirical approach based on case studies in which design projects in different disciplines are compared. In each case study, an individual designer is interviewed and the design documents are analysed. The results in this article are based on two architectural projects, two software-engineering projects and two mechanical-engineering projects. The cross-case analysis has resulted indescriptions of design situations in these disciplines. A preliminary design frame to describe design situations in different disciplines has been derived. Based on similarities and differences in the descriptions, conclusions concerning design theory, design education and design practice are given. The most important conclusions are the following. First, designers are often not aware of their design process, but focus mainly on the product. Second, software designers more often than architects andmechanical engineers use methods to structure their overall design process.

title Improving design processes through structured reflection : a domain-independent approach
source Eindhoven University of Technology
summary In the world of designing, three fields of attention can be recognised, namely design research, design practice, and design education. Gaps exist between these three fields. In this thesis about designing, the focus is on the gap between design research and design practice. Design practice includes many design disciplines and an increasing number of multidisciplinary teams. Main problems in design practice are the communication between designers with a different background and the integration and co-ordination of important aspects during a design process. By tackling these problems, the effectiveness and efficiency of design processes in practice can be improved. The study of similarities and differences between design processes in several design disciplines and the development of support for reflection on design processes are topics that can improve design practice and that deserve more attention in design research. The goal of my research is to decrease the gap between design research and design practice in order to improve design processes. Reflection on design processes can help designers to improve their design process, its results, and the designer’s proficiency: By reflecting explicitly on the current design situation and on the performed design activities, in a systematic way and on a regular basis, designers can plan next design activities that can be performed effectively and efficiently given the design goal at that moment. In this thesis, the combination of systematic and regular reflection is called structured reflection. To improve design processes in various design disciplines in practice, the study of similarities and differences between design processes in several disciplines can be useful. Similarities between design processes are the basis for domain-independent design knowledge (as distinguished from domain-specific design knowledge). To reach the goal of my research, I have chosen to combine, in a broad explorative study, the development of support for structured reflection on design processes and the development of domain-independent design knowledge. This thesis describes a domain-independent approach to improve design processes through structured reflection. My research process can be summarised as follows. I studied three design disciplines, namely architecture, mechanical engineering, and software engineering. To get input from design practice, I did qualitative empirical research: I performed twelve case studies in the three disciplines to inventory characteristics of design processes and I compared the cases for similarities and differences. The similarities, together with the results of a literature study, have been the basis for the development of domain-independent descriptive design knowledge. The developed descriptive knowledge, in turn, formed the basis for developing domain-independent prescriptive design knowledge. At the end of the project, I confronted all results with design practice to get feedback on the results in another empirical study and I performed a literature study to position the results in the design literature. My design philosophy and design frame are the descriptive results developed to answer the first research question, namely “How to describe design processes in a domain-independent way?”. My design philosophy is a set of domain-independent concepts and terms for describing a design process. The concepts and terms are based on an application of the general theory of state-transition systems to the context of designing; the concepts of state and state transition correspond to the main concepts of design situation and design activity in my design philosophy. The answer to the first research question given by the design philosophy is refined in a design frame: The design frame offers a means to structure the description of a design process in a domain-independent way. Major structuring concepts of the design frame are dimensions and subjects. I define three dimensions, namely level, perspective, and time. These dimensions define a three-dimensional space, called a positioning space, in which important aspects of design processes can be positioned. A positioning space must be defined for each subject, being the three parts of a design situation: the product being designed, the design process, and the design context. My design frame is a domain-independent structure formed by the combination of the three dimensions for each subject. My design method is the prescriptive result developed to answer the second research question, namely “How to support structured reflection on design processes in a domain-independent way?”. My design method is a domain-independent aid that offers designers support for reflecting on design processes in a structured way. Reflection on design processes is defined as an introspective contemplation on the designer’s perception of the design situation and on the remembered design activities. A reflection process is described as a process that consists of three steps that are called preparation, image forming, and conclusion drawing. The design method is based on two main concepts: The first concept is the systematic description and analysis of design situations and design activities by means of forms and checklists; only systematic support for the preparation step of a reflection process is developed. The second concept is the idea of design sessions, introduced to stimulate designers to reflect regularly during a design process. A design session is defined as a period of time during which one or more designers are working on a subtask of a certain design task, for example, one afternoon, a whole day, or a week. Both concepts are combined to support structured reflection on design processes. The complete design method consists of five steps for each design session, namely planning a design session, defining the subtask of the design session, reflecting at the beginning of a design session, designing during the core of a design session, and reflecting at the end of a design session. A prototype software tool, called ECHO, has been developed to explore the benefits of using a software system to facilitate the use of the design method. Together, the design philosophy and the design frame offer concepts, a vocabulary, and a structure to describe design processes in a domain-independent way. The design method is a first proposal of a method that supports structured reflection on design processes. My results are thus possible answers to the mentioned research questions and are starting points to improve the effectiveness and efficiency of design processes. Based on the feedback I collected, I am optimistic about the applicability of my results in design practice. By asking input from design practice and by developing results that are useful for design practice and that contribute to design research, I contribute to decrease the gap between design research and design practice. The most important recommendations for further research are to test all results extensively in design practice and to investigate how to apply the results in design education.

title An information management model for concurrent construction engineering
source Automation in Construction 5 (4) (1996) pp. 343-355
summary Projects in the construction industry are increasingly characterised by large numbers of actors working concurrently at different locations and using heterogeneous technologies. In order to support this kind of collaborative engineering, project information needs to be conceptually modelled throughout its lifecycle, along with the events that impact upon it by causing state changes. There exists, therefore, an urgent need to provide a flexible framework in which the highly interleaved and interactive events and transactions inherent in complex construction projects can be managed effectively. This paper addresses these issues by proposing such a conceptual framework consisting of four levels of abstraction and functionality governed by the COMMIT (Construction Modelling and Methodologies for Intelligent inTegration of information) Information Management Model (CIMM). A comprehensive presentation of the CIMM (which tackles issues such as versioning, notification, object rights and ownership) is given. The CIMM also facilitates the recording of the intent behind construction project decisions, thereby providing a complete project history. Finally, the model is illustrated through two proposed scenarios dealing with selected objects' lifecycles during design stages and actor transaction management.

title The Virtual Community

summary Cyberculture authority Howard Rheingold was the first to write about online communities in this style that is part-travelogue and part-anthropological guide. This groundbreaking classic explores the entire virtual community, beginning with a selective but probing look at the author's original online home, The Well. Rheingold relates plenty of anecdotes that demonstrate the upsides of online life, such as how he was able to get information on removing a tick from his child before his doctor could respond to his phone call. But the bulk of the material relates to how individuals interact online much as they do in a face-to-face community. Rheingold speaks to how both friendships and enmities are formed online and how people come together to support each other through misfortune. He gives the example of how computer-moderated communication enabled members of one Well community to send vital medical aid to a friend hospitalized halfway around the world. Rheingold goes on to show how communities can form by various electronic communication methods, using the conferencing system of The Well as one example. He also examines how people interact through mailing lists, live chat, and the fantasy cyberenvironments of online role-playing games. In the process, he questions what kind of relationships can really be formed in a medium where people can change their apparent identity at will. This book questions whether a distinction between "virtual" communities and "real-life" communities is entirely valid. The Virtual Community argues that real relationships happen and real communities develop when people communicate upon virtual common ground. Rheingold also shares his far-reaching knowledge of how technology effects our social constructs. If you are involved in an online community, here is your cultural heritage.

summary In many three-dimensional imaging applications random shaped objects, reconstructed from serial sections, are isolated to display their overall structure in a single view. This paper presents an algorithm to control an ordered search strategy for locating all contours of random shaped objects intersected by a series of cross-section image planes. Classic search techniques in AI problem solving and software for image processing and computer graphics are combined here to aid program initialization and automate the search process thereafter. Using three-dimensional region growing, this method isolates all spatially connected pixels forming a structure's volume and enters image planes the least number of times to do so. An algorithmic description is given to generalize the process for controlling search in 3-D image data where little core memory is available. Phantom and medical computer tomographic data are used to illustrate the algorithm's performance

Both arts, when abstracted intellectually (through mathematics) or emotionally (through phenomenological experience), share a number of ordering principles, having the same notion of crescendo in sequence and progression. Many have sought to unlock this hidden dimension to create artwork that lets our souls transcend up to the heavens. There are five different methods where architects have used music in their design approach: there are those who use harmonic proportions found in musical consonances as room dimensions to create harmonic spaces, flowing into each other like musical chords (Palladio, Steven Holl); those who believe that music is ‘design in time’ use rhythmic elements of music and apply it to their vertical surfaces and structural grids (Iannis Xenakis, Le Corbusier); those who use architecture as a musical instrument experiment with sound and acoustics to create a phenomenological environment (Bernhard Leitner, Peter Zumthor); those gifted with synethsesia (stimulating one sensory preceptor with another, e.g. seeing colors by listening to music, or vice versa) use certain musical pieces as an inspiration for form generation (Wassily Kandinsky, Steven Holl); and there are those who deconstruct an element in music and reconstruct it to architectural form, highlighting common themes between both arts (Iannis Xenakis, Daniel Libeskind). These five different methods have been the topic of research of many architectural scholars using western music as reference. The question becomes what if the musical reference is changed? Classical, rock, pop, country, jazz, and blues music are very different from one another, yet they share similar foundational musical structures. One may go further and experiment with various world music as reference, which is very different than western music in terms of musical structure. Linguists and musicologists have discussed the origins of music in relation to language. They hypothesize that cognitive elements found in language are somehow carried into the region's music. This paper documents the research of the author in this topic, discussing the digital modeling applications adopted that make such an investigation possible. The interest here is exploring how the visual space is altered when the musical reference is changed, and whether properties of the musical reference are evident in the architectural visualization. The musical references will be limited to Western Classical and Arabic music.

summary Displaying the progress of projects has been achieved by the use of planning outputs. Planning software, namely the well known WinProject™ , Time Line™ or Primavera™, allow chart displays, generally in the form of bar charts, logic diagrams and schedule reports to show it.

The aim of linking Planning and CAD systems is to display in real-time the progress of engineering projects, according its planning and control through their 2D or 3D architectural and engineering models.

This paper describes and illustrates, the development of an innovative software, that, in this way, links data from any Planning software to the popular AutoCAD producing colored 2D or 3D models of the multiple activities of an engineering project according the foreseen or real stages - not yet done, being done, completely done.

Same application examples to different engineering projects through some screen-shots of this software use, are illustrated.

summary The purpose of this paper is to reflect on the emergence of new forms, on the possibility of the new. We propose a reflection on the poetics of disruption, like creating strategies to break from the predictable, and we analyze devices adopted in art, media art and architecture. We understand a device as the set of practices that trace imbalanced processes that may create the new. Thus, by broaching the creative process, one must realize that thinking devices already represent a notable strategy of the arts, and that such devices, engendered by new media, are gradually incorporated by contemporary architects.

summary This paper aims at discussing how computational environments could give support to complex approaches of architectural design process. Focusing on generative design, the main goal is to allow the perception of architecture more as system than as object: form, structure and organization as emergences in non-linear, autoorganizational processes. It involves the interaction of a vast universe of factors and flows that performs as attractors or repellers for the architecture-systems evolution in time. The ideas presented here are results of the Master Research in Architecture and Complex Thought of Clarissa Ribeiro, and are part of a larger questioning about the relation of architectural design process and digital culture, discussed in our research group Nomads.USP [Center for Interactive Living Studies, http://www.eesc. usp. br/nomads].

source SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 453-458
summary In this article we investigate how the Archigram Group used computer logics and concepts as inspiration for architectural projects without ever actually using computers. By developing principles as varied and as pop as expendable architecture, customization, individualism, consumerism and mutation, the architects managed to work with concepts like software architecture, space of flux and dematerialization. When compared to the writings of contemporary theorists and designers of computer-mediated architecture, we see that the Archigram Group has been able to forecast much of the current concerns of the architecture that deal with digital and virtual spaces. Without literally digitalizing their projects or spaces, they have been able to achieve information-based architectural design. [Full paper in Portuguese]

summary The Archigram Group produced a number of design projects on the subject of computers, either imagining how computers might affect the life of city dwellers, or investigating what changes such machines would bring to architecture. Working with analogical tools and thinking about an abstract digital future, the Archigram architects deployed concepts that would have come to be crucial in recent discussions in architecture based on digital reality. Their research into things digital - without the aid of computers - led them into inquiring about individuality, expendability, interactivity, customisation and even virtualisation. Rendered in some of their design projects we find a number of architectural proposals which offer a new approach towards the relationship between time, space and architecture - an approach which is currently central for contemporary architecture conceived in cyberspace.

However, BIM has rarely been really assessed and its benefits are often described in generic terms. In this paper we describe an experiment in which such benefits are identified from a comparison between two design processes of the same airport building, one run in a conventional way and the other in a BIM-based approach. The practical advantages of BIM to airport design were remarkable.

summary Designers and design managers are interested in gaining a deeper understanding of the complexities of creativity and innovation (Langdon and Rothwell 1985). These two phenomena can be seen as complementary dimensions of a differentiation cycle where design plays a key value-adding role that gradually reduces through commoditisation. However, there is a lack of relevant evidence to explain the link between creativity and innovation. Creativity is increasingly considered as occurring in the interaction between the individual generator of an idea and a group of evaluators (Sawyer et al 2003). However, most studies have regarded the generation of a solution -and not its social impact- as the outcome of the creative process (Runco and Pritzker 1999). Accordingly, computational modelling of creativity has been mainly conducted in a social void (Boden 1999).

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. 515-524
summary Performative design can be understood as the combined usage of spatial analysis simulations and form generation procedures to imbue architectural form with material characteristics and behaviours which define desirable structural, environmental and economic performance. However, to date, design processes that facilitate the integration of ‘form generation’ and ‘spatial analysis’ remain under-developed, making existing performative design methodologies highly reliant upon the manual execution of analysis and evaluation procedures. This paper presents an evolutionary design process that uses integrative computational pipelines and generatively defined component-based assemblies to produce performative structures in response to solar performance. The resulting structures demonstrate how performative composite behaviour can emerge within ‘disassociated’ componential assemblies and produce complex formal interrelationships which surpass simplistic parametric logics. This offers new possibilities for conceiving highly integrated ‘morphogenetic assemblies’ and suggests trajectories for further research within the field of morphogenetic design.

summary Interactive Rendering combines the geometrical precision of classical computer graphics with the representational freedom of a paint program. It is more sympathetic to the ways in which designers use images, and overcomes many of the frustrations experienced in rendering from CAD models. The scene is generated in a standard viewing application, but saved as a specially enhanced raster image. The extra information allows the Interactive Renderer to apply brushed-on rendering effects which are sensitive to the perspective of the image. Effects can be applied locally or overall, and may be overlaid, blended and erased to create complex combinations. A huge range of treatments are obtainable, both photorealistic and not.

GDS started as a 2D drafting system, and proved more effective and marketable. Specialized applications and 3D capabilities were added gradually. Current interest is in simplifying the software, especially its user interface.

summary The Martin Centre CADLAB has recently been established to investigate software techniques that could be of practical importance to architects within the next five years. In common with most CAD researchers, we are interested in the earlier, conceptual, stages of design, where commercial CAD systems have had little impact. Our approach is not Knowledge-Based, but rather focuses on using the computer as a medium for design and communication. This leads to a concentration on apparently superficial aspects such as visual appearance, the dynamics of interaction, immediate feedback, plasticity. We try to avoid building-in theoretical attitudes, and to reduce the semantic content of our systems to a low level on the basis that flexibility and intelligence are inversely related; and that flexibility is more important. The CADLAB became operational in January 1992. First year work in three areas – building models, experiencing architecture, and making drawings – is discussed.

source Architectural research quarterly 1: 1 Autumn 1995. London, Emap press, pp. 82-95
summary Interactive Rendering combines the geometrical precision of classical computer graphics with the representational freedom of a paint program. It is more sympathetic to the ways in which designers use images, and overcomes many of the frustrations experienced in rendering from CAD models. The scene is generated in a standard viewing application, but saved as a specially enhanced raster image. The extra information allows the Interactive Renderer to apply brushed-on rendering effects which are sensitive to the perspective of the image. Effects can be applied locally or overall, and may be overlaid, blended and erased to create complex combinations. A huge range of treatments are obtainable, both photorealistic and not.

title Beyond Photorealism
source Architects’ Journal, 12/6/97
summary Computer rendering has come a long way in the last twenty years. But is it going in the right direction? Is the glossy photo-realistic image the only goal worth pursuing? And does the process of making it contribute enough to the design, or the ongoing dialogue with the client? There certainly are alternative modes of image-making. Frank Lloyd Wright, according to legend, could conceive a whole building in his head, and set it down rapidly, in plan and section. He would leave these drawings overnight to his assistant, who would set up a perspective. In the morning, FLW would spend an hour or two completing the rendering, ready for a lunch-time meeting with his clients. Today, many architects use their computers in the same way as FLW used his night-staff, to set-up an outline perspective, over which a rendering is produced by hand. Students, we observe, will often attempt to complete the rendering using a paint program such as Photoshop to apply textures and entourage in a kind of electronic collage.

title Computer-aided Art Direction
source F. Penz and M. Thomas (Eds.) , Cinema & Architecture: Méliès, Mallet-Stevens, Multimedia, British Film Institute, London
summary Computer-aided design for architects began to be possible about 25 years ago; in the last five it has become commonplace. In a few years time, it will be as ubiquitous as the word-processor is today. But the construction industry as a whole is not a sophisticated user of Information Technology. The state of affairs in the film industry is quite different; computer graphics of the utmost sophistication plays an increasingly important part in the production of film, but very little in their design. Is it possible that an opportunity is being missed? This paper is written from the standpoint of a designer of architectural CAD software, and seeks to explore the extent to which computer graphics techniques, which have proved useful in architecture, could be used in Production Design, and the simulation of Cinematography. Several experiments, using commercial software of the sort that architects find useful, have lead to the realisation that much is possible, but that a full realisation of the benefits would require software specially adapted to the task. The bulk of this paper describes the nature of this adaptation; it is in the nature of a preliminary specification for software for Computer-aided art direction. The initial investigation centred on the needs of film students; it has since broadened to look at the needs of established practitioners.

summary Photorealistic rendering requires special skills to achieve, but the result is not necessarily ideal for architectural communication. The Piranesi software provides an alternative way of producing a much wider range of images from the same geometrical model. Piranesi appears to be a 2d paint program for editing raster images, but its input includes a z-buffer. This allows painting and and pasting to reflect the perspective of the image, and many other depthrelated effects. The result is a new, and enjoyable, way of producing architectural images.

summary In the course of a study into the origins of the Ionic order, a group of fragmentary early capitals of historic importance were measured by short-range laser-scanning, and then reconstructed in their original state by means of NURBS surface modelling. Drawings, renderings and scaled facsimiles were produced from both types of model, and proved invaluable in the formal analysis of the objects by architectural historians. It is suggested that these digital methods are more objective and accurate than traditional drawings and plaster reconstructions, and the resulting datasets more sustainable and of greater value to subsequent researchers.

summary This paper presents the results of a detailed analysis of systems and concepts which make use of case-based reasoning, a paradigm from artificial intelligence (AI). The analysis focuses on the use of this paradigm in the support of design and education processes, so-called “case-based design aids”. The research aims to discover problem areas in current approaches and identify potential areas for further research with a view to improving the practical suitability of existing systems, which offer promising potential yet are rarely implemented in practice.

summary In the early and mid 1990s the idea to apply CBR to the task of designing — in short Case-Based Design (CBD) — led to a considerable number of research initiatives across the world. Several promising CBD tools and prototypes were developed and enthusiastically celebrated within the research community, seemingly announcing a promising future for CAAD. However, because the predicted breakthrough failed to appear, an in-depth evaluation of six CBD tools was conducted in 2001 in search of reasons for this limited success. At first sight the situation has not changed much since then, yet a closer look reveals CBD research still to be quite active, be it sometimes disguised. This observation, combined with our belief in CBD’s potential for aiding professional and student architects, motivated an expanded issue of the 2001 study. This issue determines the position of current CBD research within the CAAD domain and uncovers focal points set by CBD researchers and the tools they created. Additionally it analyses the role of emerging technologies in overcoming earlier identified drawbacks of CBD tools in architecture.

summary The illusion of the contents or the contents of the illusion. Our sensory universe is stimulated before a growing and unstoppable manifestation of visual communications in which a language complexity is noticed, where with too much frequency is observed an unpunished use of “ pyrotechnics and visual artifices “ for a quite dissimilar audience between which are some to be eager for noise and others of superficial sensations. When analyzing habitually good part of the production of the present design we found associate the adjectives experimental, transgressor, postmodern, fashion, funny and unstructured. The perplexity appears when analyzing those productions we only found that the order of the design is so chaotic and that he is so insubstantial, that surely it has some relation with the crisis of the language and of the content.

title Computers Graphics, and Learning
source Brown & Benchmark, Madison
summary The first of the topics begins with an overview of instructional computer graphics. This leads into an overview of the status of instructional visual research including discussions on visual perception, visual cognition, and theories on storing visual information in short-term and long-term memory. More practical application information is found in the next few chapters covering when and how static and animated graphics should be integrated into computer based instruction. The book concludes with a consideration of the role visuals play with multimedia. The useful information of each chapter is delivered with a cautious and wise nature. Rieber introduces his book with the first principle of instructional graphics, which I found to be very insightful. It reads, "There are times when pictures can aid learning, times when pictures do not aid learning but do no harm, and times when pictures do not aid learning and are distracting." The general premise throughout the book is that learning is paramount and should take center stage. He further warns the instructional designer about becoming "technocentric" (this is where technology dictates decision making) and recommends that media decisions not be made untilother instructional decisions are made. Again and again, from chapter to chapter, the reader is reminded of this underlying premise which made this book particularly effective. Another strength was the comprehensive nature of the book. There was an excellent balance of theory, research, and application to ensure the reader will gain the knowledge for appropriate integration of graphics into instructional materials. The theoretical information covers the role of visuals in communication and education, quoting many research sources for validation. There is an overview of three types of instructional graphics (representational, analogical, and arbitrary) and an analysis of their possible use in Gagneís domains of learning. Rieber states that the design of instructional graphics is strongly influenced by the inter-relationships and interdependency of the five domains. To help the reader choose the correct graphic for the job intended, a section describing the five applications of instructional graphics (cosmetic, motivation, attention-gaining, presentation, and practice) is included. It is recognized that these applications originated from Gagne's nine events of instruction.

summary This paper describes a domain-specific software development method for the creation of building simulators. The method is based on object-oriented modeling, design patterns and code generation principles. The goal is to provide customizable building simulators that exactly simulate those physical effects an application demands. The numerical accuracy and different algorithms to be used can be tailored to the application's needs. By using object models and preconfigured design patterns, a well-structured simulator model can be created. From this model, the complete product code of a simulator is generated. The patterns help to develop a complete and correct model. Each pattern describes a certain functionality and knows how to generate code to implement this functionality.

summary The focus of this paper is the process of knowledge acquisition (KA) and which role virtuality plays in this context. We argue that there are three different modes of knowledge acquisition which can be identified both in the domains of cognition and science: the empirical, the "constructive", and the "synthetic" mode. We show that the method of constructing knowledge in the virtual domain (i.e., the synthetic mode of KA) is not only a principal mode of KA in our cognition (e.g., thought experiments, making plans, etc.). It becomes increasingly important in the field of (natural) science in the form of simulations and virtual experiments. The attempt to find an answer to the question of whether simulation can be an information source for science, and to validate the computational approach in science, leads to a new interpretation of the nature of virtual models. This new perspective renders the problem of "feature extraction" obsolete.

title Computational Analysis of the Environmental Impact of Building Designs
source Carnegie Mellon University, Pittsburgh
summary Concem for the environmental implications of human activities is becoming increasingly important to society. The concept of current development that does not compromise future generations! abilities to meet their needs is a goal for many communities and individuals (WCED 1987). These concerns require the evaluation and assessment of the potential environmental impact of human activities so that informed choices can be made. Building construction and operation activities are of significant importance in view of a) national and intemational economies, 6) resource consumption, c) human occupancy, and d) environmental impact. For example, in the United States the built environment represents an extensive investment, both as an annual expenditure and as an aggregate investment. In the mid-l980’s, up to 30% of new and remodeled buildings had indoor air quality related complaints. Buildings also consume approximately 35% of the primary energy in the U.S. every year, resulting in the release of 482 million metric tons of carbon in 1993. I Methods developed to assess the environmental impact of buildings and development patterns can and have taken multiple strategies. The most straightforward and simple methods use single factors, such as energy use or the mass of pollutant emissions as indicators of environmental performance. Other methods use categorization and weighting strategies. These gauge the effects of the emissions typically based on research studies and use a weighting or effect formulation to normalize, compare, and group emissions so that a scalar value can be assigned to a single or a set of emissions. These methods do not consider the characteristics of the context where the emissions occur.

title Environmental Life Cycle Assessment in an Integrated CAD Environment: The Ecologue Approach
source Proceedings of the Eighth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-8536-5] Atlanta, 7-8 June 1999, pp. 351-363
summary Construction and operation of buildings is a major cause of resource depletion and environmental pollution. Computational performance evaluation tools could support the decision making process in environmentally responsive building design and play an important role in environmental impact assessment, especially when a life cycle assessment (LCA) approach is used. The building domain, however, presents notable challenges to the application of LCA methods. For comprehensive environmental impact analysis to be realized in a computational support tool for the building design domain, such tools must a) have an analysis method that considers the life cycle of building construction, operation, and decommissioning, b) have a representation that is able to accommodate the data and computability requirements of the analysis method and the analysis tool, and c) be seamlessly integrated within a multi-aspect design analysis environment that can provide data on environmentally relevant building operation criteria. This paper reviews the current state of assessment methods and computational support tools for LCA, and their application to building design. Then, the implementation of an application (ECOLOGUE) for comprehensive computational assessment of environmental impact indicators over the building life cycle is presented. The application is a component in a multi-aspect space-based CAD and evaluation environment (SEMPER). The paper describes the use and typical results of ECOLOGUE system via illustrative examples.

summary Computational building simulation tools have historically viewed buildings as artefacts isolated and disconnected from their contexts. At most, the external environmental conditions have been viewed as outside influences or stressors encapsulated in, for example, weather files for energy simulation or sky models for lighting simulation. In the field of environmental assessment, life cycle analysis (LCA) has followed a similar path of isolating the artefact under analysis from its context. Modeling the building artefact as a participant in multiple contexts over time so that the interactions and dependencies between the regions and the building can be adequately explored in the design process requires support for the modeling of regional areas, as well as the artefact and the related life cycle processes. Using computational design and evaluation tools can provide the computing capability required for effective design decision support. This paper presents the implementation of the affordance impact assessment method and the regional environmental simulation in Ecologue. Ecologue is the computational tool for life cycle environmental impact assessment in the SEMPER integrated building design and simulation system. Ecologue contains a building model and an environmental model. The building model is automatically derived from the shared building model of the SEMPER system. The environmental model is a combination of a representation of the processes and emissions occurring in the life cycle of buildings and an impact assessment model. The impact assessment model is a combination of a context model of the physical characteristics of a region and a sub-regional fate and transport model based on the fugacity concept.

title Inside Case-based Reasoning
source Lawrence Erlbaum Associates, Hillsdale, NJ
summary Case-based reasoning, broadly construed, is the process of solving new problems based on the solutions of similar past problems. An auto mechanic who fixes an engine by recalling another car that exhibited similar symptoms is using case-based reasoning. A lawyer who advocates a particular outcome in a trial based on legal precedents is using case-based reasoning. It has been argued that case-based reasoning is not only a powerful method for computer reasoning, but also a pervasive behavior in everyday human problem solving. Case-based reasoning (CBR) has been formalized as a four-step process:N 1. Retrieve: Given a target problem, retrieve cases from memory that are relevant to solving it. A case consists of a problem, its solution, and, typically, annotations about how the solution was derived. For example, suppose Fred wants to prepare blueberry pancakes. Being a novice cook, the most relevant experience he can recall is one in which he successfully made plain pancakes. The procedure he followed for making the plain pancakes, together with justifications for decisions made along the way, constitutes Fred's retrieved case. 2. Reuse: Map the solution from the previous case to the target problem. This may involve adapting the solution as needed to fit the new situation. In the pancake example, Fred must adapt his retrieved solution to include the addition of blueberries. 3. Revise: Having mapped the previous solution to the target situation, test the new solution in the real world (or a simulation) and, if necessary, revise. Suppose Fred adapted his pancake solution by adding blueberries to the batter. After mixing, he discovers that the batter has turned blue -- an undesired effect. This suggests the following revision: delay the addition of blueberries until after the batter has been ladled into the pan. 4. Retain: After the solution has been successfully adapted to the target problem, store the resulting experience as a new case in memory. Fred, accordingly, records his newfound procedure for making blueberry pancakes, thereby enriching his set of stored experiences, and better preparing him for future pancake-making demands. At first glance, CBR may seem similar to the rule-induction algorithmsP of machine learning.N Like a rule-induction algorithm, CBR starts with a set of cases or training examples; it forms generalizations of these examples, albeit implicit ones, by identifying commonalities between a retrieved case and the target problem. For instance, when Fred mapped his procedure for plain pancakes to blueberry pancakes, he decided to use the same basic batter and frying method, thus implicitly generalizing the set of situations under which the batter and frying method can be used. The key difference, however, between the implicit generalization in CBR and the generalization in rule induction lies in when the generalization is made. A rule-induction algorithm draws its generalizations from a set of training examples before the target problem is even known; that is, it performs eager generalization. For instance, if a rule-induction algorithm were given recipes for plain pancakes, Dutch apple pancakes, and banana pancakes as its training examples, it would have to derive, at training time, a set of general rules for making all types of pancakes. It would not be until testing time that it would be given, say, the task of cooking blueberry pancakes. The difficulty for the rule-induction algorithm is in anticipating the different directions in which it should attempt to generalize its training examples. This is in contrast to CBR, which delays (implicit) generalization of its cases until testing time -- a strategy of lazy generalization. In the pancake example, CBR has already been given the target problem of cooking blueberry pancakes; thus it can generalize its cases exactly as needed to cover this situation. CBR therefore tends to be a good approach for rich, complex domains in which there are myriad ways to generalize a case.

summary This project takes advantage of a dynamic structural quality found in high-density polymers in the development of a self-supporting lightweight structural envelope for the Nuit Blanche pavilion. The pavilion was developed to display a series of interactive art projects as part of the annual Nuit Blanche Festival in Paris. The project combines concepts from biology with digital design and fabrication methods to speculate on a new relation between structure, geometry, material and appearance. Before discussing the design research of the pavilion the paper will elaborate on our larger research goals in using digital technology to promote more environmentally responsible construction methods and the research values of projects at the scale of a pavilion.

summary Digital media, with the capacity to master complexity, has permitted an unprecedented ability to reinterpret natural processes. An infinite number of realities can emerge from their interpretations that can be developed into physical structures or spatial models that can further be appropriated to inform the design of architecture. In this paper the potential of these digital interpretations to inform architectural design processes will be discussed. Demonstrating how digital media can operate as an interface that couples information with cognitive processes I will show how digital media can be constructed in order to intensify our perception of our natural environment. Examples from projects that were developed with students during the spring semester of 2008 at Georgia Institute of Technology will be used to support the argument.

summary With Information Technology such as smart phones we use public urban space differently. For example prior to cell phones people would meet in a public space by agreeing on a specific meeting location and time. Using cell phones people meet more spontaneous. Cell phones also allow people to be engaged in a very private phone conversation in the middle of a public space. In spite of information technology creating new uses for public space urban planners are still relying on old paradigms in designing and constructing it. A workshop was formulated around the question: How can we design urban spaces for a digital culture? The achieved outcome of the workshop was the design and realization of a public space that addresses this challenge. To do that students were asked to come up with new functions for public spaces, test materials, help seeking for funding and creating partnerships with the city, the industry and nonprofit organizations. During the duration of a one-semester timeframe the studio was facing a series of challenges dealing with the design, fabrication and realization of an urban space. This paper will describe the challenges of designing urban spaces for a digital culture, the structure of the workshop, the interventions made during the process and the final project, an urban landscape titled “Urban Blanket” that was build in Midtown Atlanta.

summary Tensegrity structures are not commonly found within the current discourse of architecture. The reason may be that they can only be designed through physical form finding processes. This paper will show how architects can gain the ability to design these structures digitally utilizing physics engines that simulate these form finding processes in real time. To demonstrate this, the paper will use the Underwood Pavilion as a case study to describe a design process that replaces traditional methodologies by digital methods, suggesting a new parametric design approach for lightweight structures and envelopes.

title Digital Girih, A Digital Interpretation of Islamic Architecture
source International Journal of Architectural Computing vol. 10 - no. 1, 1-12
summary The relation between texture, pattern and massing is a fundamental question in architecture. Classical architecture, as Leon Battista Alberti states in De Re Aedificatoria, Book VI, Chapter 2, is developed through massing and structure first; texture is added afterwards to give the bold massing and structure beauty [I]. This hierarchy has of course been challenged throughout architecture history. This paper will provide a different thinking of the relationship of massing and texture in Islamic Architecture from a digital point of view. An analysis of Islamic patterns challenged this relationship in Islamic architecture. Digital design and fabrication methods for a series of studies and an installation were used to respond to the findings of the analysis.

summary During the summer of 2014, a unique pedagogical prototype was initiated and tested through a short five-week digital design build workshop lead by Professors Gernot Riether and Andrew John Wit at Ball State University in Muncie, Indiana. Unlike the typical design studio typology where projects are initiated through a series of top down predetermined project frameworks, this studio allowed for projects to emerge through student’s navigating an area of research in digital design and fabrication. The studio was supplied by nothing more than an entrepreneurial mindset, initial budget and the requirement that an architectural project would be realized at full-scale by the end of the semester. Over the course of the semester, students tested, stumbled and pressed through a series of follies and prototypes that resulted in the realization of the Underwood Pavilion. This paper explores a novel design pedagogy, through the lens of this Digital Design Build Studio.

source Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary The main goal of this paper is to investigate, through some space configurational based tools, a quite common phenomenon found in many different locations in Brazil, concerning the process of urban changes individually introduced by dwellers of public housing estates. A significant number of housing estates, particularly those designed according to rationalist concepts, seem to be unable to support space related social requirements and are then widely transformed when compared to the original layouts. Beyond the quantitative features, the morphological changes that take place in those housing estates mean a fundamental new approach to understand how completely new urban structures can arisefrom the space produced by a comprehensive urban design, took as a starting point for the transformations made by the dwellers of those settlements. As a case study is analysed the Rubem Berta Housing Estate which was built in Porto Alegre/RS, Brazil, for 20,000 people in the late 70’s. Since the begining of its occupation in 1986 and the invasion that took place in 1987, the urban transformations there have never stopped. It’s possible to realize that the dwellers individually use some constant physical rules to define the new settlement which are very similar within the estate itself and, at the same time, very similar to those found in other transformed housing estates of this sort. The physical rules introduced change the features of the entire settlement in two different levels: a) locally, through the transformations introduced in order to solve individual needs; b) globally, the local rules of physical transformations produce a new overall structure for the whole urban complex. The knowledge of this process makes it possible to bring to the surface of architectural theory some generic configurational codes that can be used as a tool for designing public housing estates in Brazil.

summary This research started with of a literature review about the importance of drawings as a design and a thinking tool, and the changes introduced by digital media in the production of drawings and in the design process. The study led to a discussion about how digital media interferes in the architectural practice, and how digital tools have reduced the use of hand drawings. A pedagogical experiment was developed with senior architecture students in a studio course during one semester. The experiment was preceded by a pilot study, in which the equipment was tested. The equipment used in the experiment was a frontal projection interactive white board. We expect that the results of the experiment will help establishing the systematic use of interactive displays in the studios in our school and elsewhere.

title Technologies for interactive displays [Tecnologias de displays interativos no processo de projeto arquitetônico]
source SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary This paper aims to discuss the possibilities of interactive displays in architecture´s design, the article starts discussing how the computational methods transformed the way of thinking architecture. Then are presented and analyzed some technologies that can be built into the workshop of the project architecture, among them: opaque and LCD tablets, chambers of immersion, whiteboards and interactive screens and equipment´s of tangible digital information (Tangible Bits). It appears that the trend of technological innovations is a mix of traditional and digital, facilitating the manipulation and production of drawings by architects through direct touch, some of the technologies are already considered viable, providing low cost and good results during the practice of design.

title Methods of control for robotic brick masonry
source Automation in Construction 4 (4) (1996) pp. 281-292
summary The major use of brick masonry units in the U.S. is in facades for office buildings and single family homes. The traditional method for building masonry walls is on-site by bricklayers. An alternative method is panelization or prefabrication of brick panels in a plant environment. While many mechanical problems exist, the real-time control represents a challenging aspect of robotizing brick masonry work. This paper presents an effort to study the development of an experimental robotic masonry system and its relevant control modules. It also describes two control frameworks for different levels in a robotic brick masonry prototype: (a) local control, and (b) global control. The local control system includes three work cells: (a) gripping and handling, (b) quality control, and (c) brick placement. First, the components and equipment used in a work cell are listed, then the experimental work performed with them is discussed to show how sensors are used for dehacking, brick placement, brick color detection, and brick size measurements. The paper then continues to describe a global control system that will integrate the three local work cells utilizing a hierarchical structure.

summary In a public design, such as a landscape, it is important that the information on the design process be shared among the planners, the administration, and the citizens, and to continue the design work with consensus. A landscape design proposal cannot be reasonably evaluated from only the result of a design since the decision making process would not be sufficiently explained. Therefore, designers are required to record and store several design documents during the design process. The development of a knowledge management technique is desirable in order to facilitate the sharing of the project information in the designer’s group. The authors have researched knowledge management in a landscape design process, developed a heuristic knowledge-sharing tool that aids decision-making by consensus in a design process. This tool is a sheet system based on XML (extensible markup language). It allows the user to retrieve knowledge from a similar design project, and to customize the formats of a sheet according to the design process.

title The Genetic Code of Drawing: A systemic – functional approach to the semiotics of visual language
source International Conference on Generative Art
summary The many varied drawing conventions, invented by human cultures world-wide to depict experience of their world on a two-dimensional surface, all derive from the two fundamental processes of selection and combination of marks and surfaces. Here is the DNA of drawing – a dialectically entwined pair from which spirals the luxuriant diversity of human visual representation. Recent work by visual semioticians Michael O’Toole, Gunther Kress and Theo van Leeuwen has extended earlier insights of the linguist Michael Halliday to arrive at a powerful means of analysing painting, sculpture, architecture and graphics. Such analysis is known as systemic-functional semiotics because it identifies from within a visual grammar and vocabulary the systems of choices which enable the social functions of all human communication to be articulated. Those functions are: 1. to represent aspects of our physical and emotional experiences of the world. 2. to afford both artist and viewer the means for expressing or adopting personal attitudes and moods towards those experiences. An interpersonal function. Of course, a third function is required to make the previous two visible: 3. the functon of composition in material form. This kind of semiotics recognise that ideological constraints within a society can determine the choices of visual elements and the rules of their combination; it also recognises, dialectically, that the visual work thus produced may in turn affect the society’s ideological constructs. The paper breaks new ground by extending the concept of social semiotics into the field of Drawing. It goes on to explain an ecological approach to understanding visual perception, and attempts to synthesise aspects of this perception theory and semiotic theory. The resulting synthesis becomes a way of mapping the varieties of drawing which are generated from what may be termed the ?genetic code? of drawing. But this new theoretical model proposed here not only allows us to make contextual sense of existing drawing; it also provides a means of generating new ways of drawing.

title Semiotics and Generative Art
source International Conference on Generative Art
summary The paper begins with a brief explanation of David Marr’s computational theory of visual perception, and his key terms. Marr argued that vision consists in the algorithmic transformation of retinal images so as to produce output of viewer-centred and object-centred representations from an input at the retinae. Those two kinds of output, the viewer-centred and the object-centred representations, enable us to negotiate the physical world. The paper goes on to suggest that the activity of Drawing is comparable as a process of transformation: a picture is a transformation from either viewer-centred, or object-centred descriptions, or a combination of both types of representation, to a two-dimensional drawn representation. These pictures may be described as resulting from algorithmic transformations since picture-making utilises specific geometric procedures for transforming input (our perceptions) into output (our drawings). However, a key point is made about such algorithms: they are culturally-determined. They may be defined in terms of the procedure of selecting and combining choices from the matrix of semiotic systems available within a particular social context. These systems are presented in the paper as a Chart, and are further correlated with the social functions of a communication system such as Drawing. Thus, the paper proposes a systemic-functional semiotics of Drawing, within which algorithms operate to realise specific cultural values in material form. Familiar algorithms are illustrated, such as those governing the transformation of the physics of an array of light at the eye into the set of representations known as perspective projection systems; and also illustrated in the paper are less familiar algorithms devised by artists such as Kenneth Martin and Sol LeWitt.

title Algorithms of the Mind. The generative art of drawing
source International Conference on Generative Art
summary Throughout the disciplines of art and design, interest in the possibilities of algorithmic methods for generating two- and three-dimensional visual forms grows apace. Evidence supporting this observation may be found in the increasingly diverse range of contributions to the Generative Art conferences. Two research scenarios may be identified: 1 in which the generative process itself is the object of research, 2 in which the forms generated are the objects of research. The question of what criteria may be appropriate to the evaluation of such research is addressed in this paper. Lincoln and Guba's term "criteria of authenticity" is elaborated in a case study based on the author's research into teaching drawing to fine art undergraduates. Although the drawings produced are not computer-generated, it is argued that the concept of 'algorithm' as a set of rules for the generating of visual representations may be usefully applied to the mental ontological constructions, or 'mind-set', of the student. Such mind-sets affect the ways that drawings are constructed. It is suggested that a teaching method which enables students to recognise their mental algorithms as cultural constructions, may also empower them to reconstruct those algorithms in order to generate visual representations previously unimagined.

title Drawing as Transformation: From Primary Geometry to Secondary Geometry
source International Conference on Generative Art
summary A distinction is made between primary geometry, the arrangement in space of lines of projection from a 3-D object to a plane of projection, and secondary geometry, the relationships between the points, lines and shapes of the drawn projection on a 2-D surface. Drawing projection systems, such as those classified under British Standard 1192, are illustrated, and are shown to be defined in terms of primary geometry. It is argued that a re-classification of projection systems in terms of secondary geometry enables first-year students of drawing to relate more easily such systems of geometry to their observational experiences. Student drawings illustrate the argument.

title Autopoiesis
source International Conference on Generative Art
summary Autopoiesis, is a series of fifteen musical and robotic artificial life sculptures that interact with the public and modify their behaviors based on the both the presence of the participants in the exhibition and the communication between each separate sculpture. Autopoiesis is "self making", a characteristic of all living systems. This characteristic of living systems was defined and refined by Francisco Varella and Humberto Maturana. This series of robotic sculptures talk with each other through a hardwired network and audible telephone tones, which are a musical language for the group. Autopoiesis presents an interactive environment, which is immersive, detailed and able to evolve in real time by utilizing feedback and interaction from audience/participant members. The interactivity engages the viewer/participant who in turn, effects the system's evolution and emergence. This creates a system evolution as well as an overall group sculptural aesthetic.

summary Collaborative teamwork often goes beyond same place - same time situations: new information technologies allow for distributed asynchronous cooperation. In urban planning procedures, the elaboration of a land-use or building plan may be considered as the common goal of all actors. But in general, the participants do have conflicting subgoals. Computer supported cooperative work (CSCW), therefore, must include tools that allow for discussions in distributed workgroups. GMD's Zeno system aims at structuring such argumentation processes and at mediating between opposite interests.

summary This article is a summary of a thesis project directed under the supervision of Wassim Jabi and Mehrdad Hadighi] This thesis is based on the premise that space can be created by the interaction of physical and ephemeral elements with the human body. The physical elements create a frame on which the ephemeral rely, but it is the interaction between them that produces a distinct experience of space and place. Extensive and diverse preliminary explorations range from the use of digital media in the design process, video and multimedia as a revolutionary element in 20th century art and light as a way of expression for architectural installations exploring new media. From this body of information it was conceived that certain new media add an important and particular dimension to the traditional physical medium of architecture. This constitutes a controversial and innovative approach to the creation of space and most importantly to the experience of place.

summary Through the evaluation of advantages and limitations of 3D historic city models, this paper aims to analyze the contribution of those tools to the city history representation. One should overcome limitations such as incomplete information, impediments to acknowledge hypotheses representations, intense labor requirements or difficulties to encourage a deep reflection. We identify some significant characteristics of those systems based on historical facts’ location in 3D models, different files association, dynamic databases and interaction, which should prevail over some of the limitations. Finally, we illustrate those issues through the system Rio-H that presents an alternative for historical narratives.

summary This paper aims to analyze interactive multimedia and visualization techniques for architectural theory publications. Unfortunately, the available literature about multimedia, visualization, hypertext and related systems in this area is not consistent. The majority of articles present descriptions of ideas, designs, and prototype or working systems claimed to be advantageous on the basis of the author’s intuition and lacking useful evaluation on their utility and ease of use for their intended users. The paper reviews the features of a research project outcome, which investigates an iconic building of the late 1930’s in Brazil. It examines the differences and similarities between a hypertext/multimedia system – a CD-ROM – with a comparable non-hypertext or non-computer product – a book – that deals with a specific subject: Architectural Theory.

summary The accelerated rate of change that we live nowadays, demands professionals to develop new learning skills to cope with it the rampant development of information technology opens up new horizons and challenges in the way that a human being can be formed through education. In response to the technological progress and rapid rate of change, the Tecnológico de Monterrey System has redesigned its education model, focusing on learning rather than teaching. This means not only acquiring knowledge on theory and concepts, but also learning skills, attitudes, and values that make students be committed with their community & country needs. It also means to be competitive in their area of knowledge at the international level. A central element in the new educational strategy is the technological platform where the academic courses are developed. This platform helps students and professors to do a great deal of the course activities on a lap-top through the computer the interaction between students with students, or professor with students has increased. At the Tecnológico de Monterrey System the implantation of the educational strategy has meant the creation of training programs for teachers, and technological development & support to attend over 5,000 teachers and 70,000 students.

summary At the beginning of the sixteenth century, the Aztec capital, Tenochtitlan, was one of the world's largest cities. By 1521, the Spaniards under Hernan Cortes had destroyed both the Empire and the city. Tenochtitlan was razed to its foundations and Mexico City was built on top of it (Matos, 1993).

This paper discusses the process for developing digital interpretations of the Teocalli or Ceremonial Precinct of Tenochtitlan based on historical, iconographical, and archaeological materials. To this end, digital models were constructed by taking into consideration Aztec archaeoastronomical principles and measuring systems. The result is an interactive view of the Ceremonial Precinct, perhaps the most comprehensive since Tenochtitlan was destroyed more than 500 years ago. This project has been recently published on CD-ROM.

summary This paper illustrates a shift in the fundamentals of cinema which is being augmented in social and techni- cal terms. The primary changes deal with the perception of spectator-actor and with the new digital technologies being utilized. This paper will be structured around the four "tyranny" that, as Peter Greenaway has suggested, are destroying film: The need of the camera, the current frame (screen), the text as the axis of the narrative and the importance of the actors. An augmented understanding of cinema offers a new aesthetic in terms of space, interaction and ultimately an open and generative cinematic experience.

source SIGraDi 2004 - [Proceedings of the 8th Iberoamerican Congress of Digital Graphics] Porte Alegre - Brasil 10-12 november 2004
summary Recent explorations of the concepts of form and content in virtual worlds open a new understanding of the development of novel design paradigms that can induce the sense of presence in virtual worlds. This paper presents current research in the design of presence in virtual worlds. It investigates the impact of two paradigms that integrate the components of form and content: the first is termed: “scenario- based design” and the second is termed: “performance-based design”.

title Enabling Low Cost Human Presence Tracking: Using commodity hardware to monitor human presence in workplaces
source Living Systems and Micro-Utopias: Towards Continuous Designing, Proceedings of the 21st International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2016) / Melbourne 30 March–2 April 2016, pp. 45-54
summary Finding automated methods to track the presence of hu- mans can help designers understand workplaces. Methods to under- stand the patterns of human movement in workplaces using beacons, badges and sensors are being developed. Whilst the results are promis- ing, they can be costly and may require the manual setup of expensive equipment. The Global Positioning System (GPS) is widely adopted due to its high degree of accuracy, however, is inapplicable in indoor environments due to the physical limitations of satellite attenuation. There is no comparably ubiquitous positioning system that can be used to make device-driven position tracking that is specifically adapted to indoor environments. With the increasing popularity of phones, watches and fitness tracking bands with WiFi and Bluetooth connectivity, we explore the potential of these wireless radios as a low-cost alternative to monitor human movement. As the costs of technology continue to decrease, the means to build a low-cost tracker through WiFi and Bluetooth enabled devices in an indoor environment become possible. Furthermore, is it possible to develop a low-cost tracking device using only commodity hardware that is able to accu- rately automate and record presence in space with sufficient veracity?

summary The advent of the Internet has opened up and given, particularly, the developing countries and the world in general, a transformation into collective intelligence (Levy, 1998) societies linked to digital communication (Rafi, 2001). Apart from large corporations, the rapid evolution of border-less communication has also synergise between the art and science expertise to form low-cost internet-based networks that have become multi-million dollar companies within a short period of time (e.g. Linux) (Rafi, 2001). In the context of architectural designs and construction industries, the birth of Internet-based CAD (iCAD) solutions has offered a new dimension to architectural practice. The function of CAD has expanded as a tool to communicate and collaborate as well as to better control all phases of the architectural practices. This paper will review the current available iCAD tools and explore the possible utilisation of iCAD in architectural practices. The opportunities for modifying current professional practice standards to best use iCAD will be rationalised as well as the elements in ensuring the effectiveness of iCAD implementation. The final component of the paper will be an evaluation framework to measure the value of iCAD in an architectural practice. The framework will become an early platform for an architectural practice to decide and plan their future in utilising and applying iCAD in the most efficient way.

title Perfect Distribution Phenomenon and the Origin of the Spacetime Harmony

summary Perfect Distribution Phenomenon (PDP), namely one- (t=1) and t-dimensional (t>1) Ideal Ring Relationships (t-D IRR)s are cyclic sequences of integers which form perfect partitions of a finite interval [1,s] of integers. The sums of connected sub-sequences of an IRR enumerate the set of integers [1,s] exactly R-times. Example: The 1-D IRR {1,3,2,7} containing four elements (Fig.1) allows an enumeration of all numbers 1=1, 2=2, 3=3, 4=1+3, 5=3+2, 6=1+3+2, 7=7, ... 13=1+3+2+7 exactly once (R=1).

summary Following the evolution of human-computer interaction to date, intelligent user interfaces (IUIs) seem to be one of the most important paradigms for future research. “Intelligent” or quasi-intelligent behaviour may be applied to both virtual (intelligent virtual environments) and real space (Ambient Intelligence). This paper focuses on the augmentation of physical space as a characteristic of the latter case. More specifically, this paper briefly examines Ambient Intelligence and the concepts on which it is based, documents the importance of Ambient Intelligence (AmI) technologies for the formulation of the user’s spatial experience and attempts to outline some important theoretical approaches to human behaviour and communication that need to be considered during the design, implementation, and evaluation of Ambient Intelligence systems. Ultimately, this paper aims to outline the influence of said technologies on the users’ activity within the environment and their environmental experience in general.

summary For some years ICT (Information and Communication Technology) has been worldwide a hot topic and, especially in the European academic environment, a very fashionable word. No matter where the road would lead to, almost any ICT related project was welcomed as the next step towards a brand new and even better system of education. In the meantime CAAD (Computer Aided Architectural Design) plays a role of utmost importance during a range of stages in the design process or building project.In this situation a research project is set up to develop an educational environment where CAAD meets ICT. The first application was turned down as the proposed (ICT) technology wasn’t available, according to committee judging. After proving them wrong, the second application was more successful. Even though the project was set up for local values, education in CAAD and related topics in Belgium, it was situated in a networked (internet) world.After running the project for a period of two years a list of pros and cons can be made up. Moreover, both local and on a global scale, ideas have changed.

title Why Architects Draw
source The MIT Press, Cambridge, Massachusetts
summary For nearly twenty years Edward Robbins, an anthropologist, has been studying and writing about the system of architectural education and practice in the United States and abroad. In this book he examines the social uses of architectural drawing: how drawing acts to direct both the conception and the production of architecture; how it helps architects set an agenda, define what is important about a design, and communicate with their colleagues and clients; and how it embodies claims about the architect's role, status, and authority. The centerpiece of Robbins's provocative investigation consists of case study narratives based on interviews with nine architects, a developer-architect, and an architectural engineer. The narratives are illustrated by the architects' drawings from projects in Japan, England, Italy, Germany, Spain, Portugal, and the United States, from conception through realization. Included are orthographic and axonometric projections, perspectives, elevations, plans, sections, working drawings, sketches, schematics, construction, and finished drawings. Drawings and interviews with: Edward Cullinan, Spencer de Grey, Jorge Silvetti, Renzo Piano, Alvaro Siza, John Young, Itsuko Hasegawa, William Pedersen, Rafael Moneo, Rod Hackney, Peter Rice.

summary The use of digital design and fabrication technology for the integration of joints into timber plate structures has been the subject of recent research in the field of architectural geometry. While most of research has been focused on joint geometries, assembly sequences, and the fabrication of smaller prototypes, there have been few implementations in buildings. This paper illustrates the challenges for such a process and offers our solutions for implementing it at a building scale through the example of a theater hall built from cross-laminated timber plates. The building achieves its column-free span of 20 meters with a plate thickness of only 45 mm through a form-active lightweight structure system. It combines prismatic and antiprismatic folded surfaces and a double-layered cross-section with integrated thermal insulation.

summary This paper is a report of a doctoral research seminar conducted during the Winter term, 1987. The interdisciplinary seminar investigated both theoretical and practical aspects of how design decisions are made. Participants in the seminar represented diverse interests ranging from human science to computer-aided design. The paper focuses on two of several decision making issues that emerged from this seminar: design rules and design languages. These issues are explored from a theoretical context and illustrated through design experiments and discussions that were conducted as part of the seminar. The paper concludes with several suggestions for the development of computer-aided design software.

source Education for Practice [14th eCAADe Conference Proceedings / ISBN 0-9523687-2-2] Lund (Sweden) 12-14 September 1996, pp. 381-386
summary Whilst it is often argued that computers have an positive role to play in the educational process, design tutors frequently view computer based design work as being of inferior quality to that of designs produced by traditional means. This may be no fault of the technology, but more likely a consequence of a student’s inappropriate use of that technology. It could be argued that part of the role of the design tutor is to encourage students to use technology in a more appropriate way, rather than to totally discourage the use of computers in their designs. The introduction of computer technologies has led to new ways of designing, which may be very different to the methods of design that are traditionally taught. This paper proposes that the successful implementation of CAAD in Architectural design education, can only be achieved if design tutors fully appreciate and embrace these new design methodologies, in a way which extends beyond the need to simply accept the new technology.

summary The quartet project is a four-week programme undertaken by all first year B.Sc Architecture students at the Welsh School of Architecture. It takes place early in the first semester and is designed to encourage students to develop a series of transferable skills. The cohort is divided into four groups, and the groups rotate around four different activities on a weekly basis. One of these activities is CAD/IT and aims to equip students with the necessary understanding of the potential and limitations of using computers as part of their studies, with emphasis on the creative use of the technology. Throughout the week links with the other three activities are heavily stressed and students use computers within all four activities to some extent. Using examples of students' work from the past two years, this paper aims to assess the CAD/IT element of the project, and how it connects with the other activities. It then looks at how the skills developed during the week are utilised by the students during the remainder of their time in the school.

summary This paper is based upon the premise that Computer Aided Learning (CAL) has been poorly integrated into schools of Architecture and it identifies some of the barriers that have prevented this. The Built Environment Appropriate Technology for Learning (BEATL) project aims to promote a climate of change within which these barriers can be crossed. The focus of BEATL is on providing a framework within which technology assisted teaching can be adopted for particular elements of taught courses through a process of module pairing, and collaboration between Built Environment faculties at three UK Universities. The paper discusses the early stages of the Project and outlines the methodologies developed for embedding and transferring innovations between institutions, the support of 'Educational Technology Officers' and the evaluation strategies being utilised. Early results indicate the benefits of a focus on a individual element rather than a whole module and that generic innovations tend to be more successfully transferred than 'off the shelf' Computer Aided Learning products.

source Computers in Design Studio Teaching [EAAE/eCAADe International Workshop Proceedings / ISBN 09523687-7-3] Leuven (Belgium) 13-14 November 1998, pp. 131-138
summary This paper traces the relationship of CAAD with creative studio work within a ‘year based’ school of architecture where the curriculum is founded on a series of ‘Core Projects’. These ‘Core Projects’ are structured so that undergraduates undertake a structured study of the essentials of architecture in an orderly progression. Within this pattern CAAD is not a stand-alone subject or module and as students do not work in units, it is difficult to run specialist CAAD options. The subject is regarded as another skill in communication and tuition in CAAD is provided as part of the acquisition of central architectural skills. CAAD, therefore is regarded as one of the components of skills and knowledge needed to support and the ‘Core Projects’ which account for about 70% of the course assessment. The paper will analyse the evolution of CAAD education within this kind of course in Architecture, reflecting on some of the tensions that have arisen through this and use student work to illustrate some of the lessons learnt over this period

summary This paper looks at the potential for the Virtual Reality to be used as a medium for the development of teaching tools in Architectural and Urban Design Education. It identifies examples and lessons learned from the development of teaching tools in other disciplines. The paper outlines a prototype system developed at Cardiff University to help Town Planning students understand the three dimensional nature of site planning and design. This was developed following difficulties encountered by students in using CAD which was seen as insufficiently intuitive to allow effective use within the short timespan available. The prototype system allows students to access their site through the familiar environment of a Web Browser. A number of 'Standard' house types are available which can be selected and inserted into the design space. Once in the space the houses can be viewed in three dimensions, moved and rotated in order to form any configuration that the students may wish. The system is easily customisable; it need not be limited to uses in urban design, but could be used in many situations where component parts are arranged in space.

summary The assessment of architectural design project work, which forms the majority of the work produced by students in schools of architecture, is usually assessed through the process of critical review (otherwise known as a ‚crit‘ or jury). The traditional method of critical review usually involves the student describing work displayed on a wall directly in front of a panel of critics. Difficulties emerge when students wish to incorporate dynamic, computer generated content into their presentations. Architectural practice is increasingly turning to the ‘PowerPoint’ slide show as a means to communicate their work to clients, and this technology is often better able to incorporate dynamic content. This paper describes a comparative study, whereby students work is presented in both slideshow and pin-up formats to a panel of reviewers. The reviewers were able to evaluate the value of the two forms of presentation in terms of their ability to conduct critical reviews. Results suggest that whilst the slideshow method allows the reviewers to gain a reasonable understanding of the student’s project work, they found it more difficult to provide useful feedback to the student on their design project work.

summary Visualisations are generated of diverse data and use many different techniques and visual methods. It is often beneficial to evaluate what is being visualised and how the visualisation is made up. Such an analysis may aid the developer to understand what 'tools' are available and help the user to reference and compare different realisations. Display models specifically classify the data by what type of output can be created. We review many 'display oriented models' and discuss important aspects of these methods and ideas. In presenting these models, we encourage their use. In particular, we focus on the symbolic reference model of Jacques Bertin. He used this model to describe images and 2D visualisations. We translate Bertin's scheme into algebraic form such as a method to decribe visualisations.

summary This paper presents a methodology for evaluating text editors on several dimensions: the time it takes experts to perform basic editing tasks, the time experts spend making and correcting errors, the rate at which novices learn to perform basic editing tasks, and the functionality of editors over more complex tasks. Time, errors, and learning are measured experimentally; functionality is measured analytically; time is also calculated analytically. The methodology has thus far been used to evaluate nine diverse text editors, producing an initial database of performance results. The database is used to tell us not only about the editors but also about the users - the magnitude of individual differences and the factors affecting novice learning

title Information visualization using 3D interactive animation
source Communications of the ACM 36(4): 57-7 1
summary UI innovations are often driven by a combination of technology advances and application demands. On the technology side, advances in interactive computer graphics hardware, coupled with low-cost mass storage, have created new possibilities for information retrieval systems in which UIs could play a more central role. On the application side, increasing masses of information confronting a business or an individual have created a demand for information management applications. In the 1980s, text-editing forced the shaping of the desktop metaphor and the now standard GUI paradigm. In the 1990s, it is likely that information access will be a primary force in shaping the successor to the desktop metapho. This article presents an experimental system, the Information Visualizer (see figure 1), which explores a UI paradigm that goes beyond the desktop metaphor to exploit the emerging generation of graphical personal computers and to support the emerging application demand to retrieve, store, manipulate, and understand large amounts of infromation. The basic problem is how to utilize advancing graphics technology to lower the cost of finding information and accessing it once found (the information's "cost structure"). We take four broad strategies: making the user's immediate workspace larger, enabling user interaction with multiple agents, increasing the real-time interaction rate between user and system, and using visual abstraction to shift information to the perceptual system to speed information assimilation and retrieval.

summary Recent technological advances have made it feasible to produce full color statistical maps on computer-controlled display systems. This has caused an appraisal of the use of color to represent statistical variables, and the development of a theoretical structure for the choice of suitable univariate and bivariate map coloring schemes. Realization of such schemes in an intuitive and controlled way is important to the comprehension of statistical variables from maps. Therefore, a method of generating specific color sequences within the framework of a uniform color space, allowing for the intuitive specification of color sequences and for their realization on various display systems, is presented

summary Pittsburgh, PA: Department of Computer Science, CMU, February, 1981. CMU-CS-81-106. includes some bibliographical references. The problem of retrieving multikey records via range queries form a large, dynamic index is considered. By large it is meant that most of the index must be sorted on secondary memory. By dynamic it is meant that insertions and deletions are intermixed with queries, so that the index cannot be built beforehand. A new data structure, the K-D-B-tree, is presented as a solution to this problem. K-D-B-trees combine properties of K-D-trees and B-trees. It is expected that the multidimensional search efficiency of balanced K-D-trees and the I/O efficiency of B-trees should both be approximated in the K-D-B-tree. Preliminary experimental results that tend to support this are reported

title Architectural Research : Incorporating Myth and Science
source Journal of Architectural Education November, 1990. vol. 44: pp. 20-32 : ill. includes bibliography.
summary Despite an apparently common assumption that science and myth are totally incompatible approaches to architecture, especially as related to architectural design, the author argues that science and myth are both explanations of phenomena, each different, but both valid. Positing the desirability of a research and design process that would take advantage of both approaches, it addresses the problems of existing conceptual categories and the possible productive relationship between myth and science for architecture. Anthropology is then proposed as a paradigm for an architectural research that could address both science and myth, and this is illustrated with examples of research and design studio instruction

summary This paper describes the integration of machine intelligence into an immersive architectural sculpture that interacts dynamically with users and the environment. The system is conceived to function as an architectural envelope that might transfer air using a distributed array of components. The sculpture includes a large array of interconnected miniature structural and kinetic elements, each with local sensing, actuation, and machine intelligence. We demonstrate a model in which these autonomous, interconnected agents develop cooperative behaviour to maximize airflow. Agents have access to sensory data about their local environment and ‘learn’ to move air through the working of a genetic algorithm. Introducing distributed and responsive machine intelligence builds on work done on evolving embodied intelligence (Floreano et al. 2004) and architectural ‘geotextile’ sculptures by Philip Beesley and collaborators (Beesley et al. 1996-2006). The paper contributes to the general field of interactive art by demonstrating an application of machine intelligence as a design method. The objective is the development of coherent distributed kinetic building envelopes with environmental control functions. A cultural context is included, discussing dynamic paradigms in responsive architecture.

summary Space accepts pervasive technologies as an architectural feature inherent to design. As such, architecture is developing various links to video surveillance, crafting a new use and a new user of space. Consequently, a new type and layer of interaction is taking place in architectural space. We extend the experimental nature of 3D Virtual Environments to encompass our surveillance studies, and explore the Closed Circuit Television (CCTV). This paper contributes to the thinking of the architect positioning herself as the user of space while designing, replacing her as an empowered orchestrator of all the technologies attached to buildings.

summary In 1952 the Italian Olivetti Company opened a study laboratory on electronic calculators in New Canaan, USA; in 1955 it created an electronic research laboratory in Pisa and two years later, co-founded a company to produce electronic conductors. In 1959 it presented ELEA 9003 and in 1965 the P101, respectively the first full transistorized computer and the first desktop computer. This paper aims to investigate how the Olivetti Company accomplished in such a brief period of time a pioneer vision in the field of computing. By one hand it seeks to highlight the forerunner idea of Adriano Olivetti (1901-1960) for an integrated awareness of what computing could become and on the other hand, how that wakefulness fostered an innovative agenda among architects, designers, filmmakers and scientists for the invention of the computer as an artifact expression of an epoch. This successful endeavor anticipated what would become the concept of personal computing. Moreover the paper underlines how the early commercial development of Olivetti and IBM computing flourished in the context of the Universal Exhibitions of Brussels and New York.

summary Today the computer technique is widely adopted in both real designing and architectural educational process. The computer is used as a tool that makes the designer work easier. But if a computer user has no compositional thinking even the best technique and special programmes can't help him to get an aesthetic valuable production. However, excessive and clumsy use of architectural programmes at the early stages of architectural education, attempt to replace a free-hand drawing with a machine-made one and not complying with the composition rules led to opposite results and a full disappointment.

title Versioning: Architecture as series?
source First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 157-170
summary This paper investigates the role of versioning in contemporary theory and the practice of design. The introduction of computation done by computers allowed for complex mathematical calculations and their visualization, which were for long time simply too complex. Today, differential calculus – underlying most interactive 3D modeling software – has significantly informed the production and conceptualization of architecture. The upshot of this transformation is that we are now witnessing a shift from an architecture of modularity towards an architecture of seriality, design versions. The core idea of versioning exceeds simple variation between different parameterized design iterations, versioning rather also operates at the micro-scale, within the structure and aesthetic of digital design itself.

source Computer-Aided Design, Vol. 29 (4) (1997) pp. 279-285
summary In order to construct a 3D model from a collection of 2D images of an object, an energy function is defined between the object's images and corresponding images ofan articulated mesh in three dimensions. Repeated adjustment of the mesh to minimize the energy function results in a mesh that produces images which closelyapproximate the input images, that is to say that under the appropriate conditions it realizes a preconceived object. It has implications for model building, reverseengineering and computer vision. Minimization of the energy function is a multivariate problem of large scale with many local minima. We give an approach forsolving this problem. For certain restricted, but useful applications, intuitive solutions to the minimization are consistently obtained.

title Using concept sketches to track design progress
source Design Studies 21 (5), pp. 451-464
summary Sketching is one of the most important activities in the design and development of new products. Designers produce sketches, from concept design ideas through to highly detailed representations of product artifacts, product sub-assemblies and so on, to communicate with themselves and with others. To this end, the focus of this paper is the description of a study of student designers at work in the early stages of design, with particular emphasis on the visible sketching component of the design process. The study has been carried out to firstly investigate the sketching activity and secondly to explore methods or techniques which might improve the efficiency of this activity. In particular, the paper describes a technique, based upon three types of operation, namely lateral transformations, vertical transformations and duplication, that occur between designer's sketches. These transformations can be used to help track the designer's thinking mode which, it is envisaged, will increase the efficiency of the sketching activity.

summary Designers keep a constant record of the design process through their sketches and notes. In parametric CAD, the record of design moves is implicit and can be found in the elements upon which the parametric model is built. Current systems provide designers with limited tools for recording, viewing or analyzing the design process. We propose a system's approach to capture the design narrative as an artefact for design. The Design ReExplorer was developed to test ideas on using these narratives in gaining insights towards how models are built, exploring alternatives and supporting backtracking and deferral strategies in design exploration. We evaluate its insertion and viability in real-world scenarios through an expert panel study. The results of the study are favourable with positive feedback and multiple suggestions for future work.

source III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 126-129
summary The research on CAD has been looking for a long time a creative contribution to architectural design, including recently the use of virtual-reality as an immersive modeling system, but without much practical results. However, contemporary architecture is increasingly including digital characteristics based more on cultural influences than on the use of electronic tools. This shows an evolution of the discipline in relation to digital media and apparently distant from environmental concerns. But the works and reflexions reveal a common convergence in the role of body in architecture as a pivot between virtual and local dimension of design. Based on that relationship we propose to take advantage of virtual-reality for modeling environmental conditions of the location in order to guide architectural design, using for example the potential of representing characteristics not visible in reality or to simulate time cycles. Sun displacement, wind direction, temperature ranges, topography and landscape are specific conditions in design that define energy consumption and human comfort. Such characteristics can establish optimal shapes crossing the different variables with timelines. VR-modeling and interactive control allow an spatial evaluation of environmentally efficient forms. That is showed through an exercise of housing in different locations of Chile. This merger between digital media and ecological concerns represents a crossing of contemporary cultural trends to motivate exploration of new geometries, supported on the potential of technology and on sustainable human development

source SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 338-343
summary This work deals with the process of exploiting the potentialities of Open Source software to promote distance learning of Digital Graphics. It is considered that this modality of study should offer flexibility in terms of software choices. The GRAFICA LIVRE group emerges with an interdisciplinary character to establish collaborative space of work between students and lecturers from Computer Science Course and Digital Graphics Post-Graduation Course. The hypothesis of this study refers to the possibility of identification and development of procedures to create virtual environments using open source software. The activities defined lead to the implementation of three-dimensional multi-user environment based on open source software in both senses, used to the construction of the environment and to the development of activities to distance learning on Digital Graphics. This paper describes the methodology to structure didactic material to be accessed remotely focusing on identification and enhancement of tools to develop specific activities.

title Enhancing 3DSkyView Extension Performance
source Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Recent Advances in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Kluwer Academic Publishers, ISBN: 1-4020-24088, p. 325-340
summary This paper presents a second version of the 3DSkyView extension. The purpose of that extension was to implement a calculation algorithm for assessment and visualization of sky view factors (SVF) by means of tools available in a Geographical Information System (GIS). The sky view factor is a thermal and geometric parameter pointed out in the specialized literature as one of the main causes of urban heat islands. A 3D-GIS is a powerful tool for reaching the goal of this research because it allows the storage, treatment and analysis of tri-dimensional urban data, in addition to a high level of flexibility for incorporating calculation algorithms. The objective in the 3DSkyView extension is to optimize the determination of that factor, not only reducing its demanding calculation and graphical representation time, but also generating a simplified tool for replacing expensive photographic equipment usually applied on this matter. Enhancing functions of ArcView GIS 3.2, the first version of that extension showed a very good performance allowing the automatic delineation and determination of SVF. That performance was although limited to a single observer point. The simulation of SVF for several view points in urban canyons was only possible by applying the extension as many times as the number of observers considered. Therefore, this second version was now developed in order to allow simultaneous determination of SVF for many view points. In addition, the 3DSkyView new interface is more flexible, in a way that the user may choose the kind of output wanted (graphical and/or tabular). With this new feature it is then easier to create a continuous SVF map for an entire area.

summary The aim of this research was to investigate the relationship between the object-oriented paradigm and the design process in architecture. The work was inspired by Mitchell´s (1990) comparison between architectural types and classes of objects. An analogy was set between the development of classes and the structuring of design problems based on architectural typologies. The method was then compared to Alexander´s (1964) in terms of levels of abstraction. Two classes were implemented, illustrating the application of the object-oriented paradigm in architectural design. The method developed is expected to help architects develop a new understanding of the design process.

summary The linear logic of project process is being replaced by alternative proceedings, used simultaneously. Today this option repertory signify that the architect must assume in a conscious attitude both critical reflection and free creativity. The necessity of experimental work arise with the purpose of discovering the effects and challenges generated by hypermedial resources. This idea put in action in a workshop organized by the Centro de Computacion de la Facultad de Arquitectura, deepening in heuristic relationships between analogical and digital proceedings. The workshop was leaded by Arch. Arturo Montagu and coordinated by the authors. The project theme was a concrete problem placed at Mar del Plata city, and was developed by professionals, teachers and students mixed groups, of different ages, objectives and experience. The replacement of analogical media, with all its representation power, for digital media was avoided -this was taken as mere translation-; instead both were considered on its complementary elements and potentialities applied to project ideation and its communication. Due to this experience it is observed that the generation of this project methodology is configured by a synthesis of heuristic and compositive proceedings, the interface design and the interaction strategies with the object. All this work have revealed its own internal logic, that stimulate us to continue on the research.

summary Digital technologies not only have made information accessible but also have exponentially generated new data. The continue growth of urban GIS and pervasive computing is helping us analyze human interactions in unprecedented ways. Yet, when researching urban sites, the students’ task is conventionally limited to the analysis of aggregate spatial data that does not reveal the invisible forces acting upon the site. The limitation of this approach is further evident if students cannot visit the site. This paper explores the role of information visualization to uncover uncommon site forces and to supplement students’ lack of embodiment with far distanced sites.

title REAL SCALE MODEL VS. COMPUTER GENERATED MODEL
source Full-Scale Modeling in the Age of Virtual Reality [6th EFA-Conference Proceedings]
summary Advances in electronic design and communication are already reshaping the way architecture is done. The development of more sophisticated and user-friendly Computer Aided Design (CAD) software and of cheaper and more powerful hardware is making computers more and more accessible to architects, planners and designers. These professionals are not only using them as a drafting tool but also as a instrument for visualization. Designers are "building" digital models of their designs and producing photo-like renderings of spaces that do not exist in the dimensional world.

The problem resides in how realistic these Computer Generated Models (CGM) are. Moss & Banks (1958) considered realism “the capacity to reproduce as exactly as possible the object of study without actually using it”. He considers that realism depends on: 1)The number of elements that are reproduced; 2) The quality of those elements; 3) The similarity of replication and 4) Replication of the situation. CGM respond well to these considerations, they can be very realistic. But, are they capable of reproducing the same impressions on people as a real space?

Research has debated about the problems of the mode of representation and its influence on the judgement which is made. Wools (1970), Lau (1970) and Canter, Benyon & West (1973) have demonstrated that the perception of a space is influenced by the mode of presentation. CGM are two-dimensional representations of three-dimensional space. Canter (1973) considers the three-dimensionality of the stimuli as crucial for its perception. So, can a CGM afford as much as a three-dimensional model?

The “Laboratorio de Experimentacion Espacial” (LEE) has been concerned with the problem of reality of the models used by architects. We have studied the degree in which models can be used as reliable and representative of real situations analyzing the Ecological Validity of several of them, specially the Real-Scale Model (Abadi & Cavallin, 1994). This kind of model has been found to be ecologically valid to represent real space. This research has two objectives: 1) to study the Ecological Validity of a Computer Generated Model; and 2) compare it with the Ecological Validity of a Real Scale Model in representing a real space.

summary Hypermedia Systems (HS) have deeply modified the methods for organizing and recovering information with respect to most traditional transmission methods; they are radically changing the experiences of reading, communication, comprehension and learning. This work aims at showing the results of a study on the consequences and the relationship between the presence of image and the positive attitudes generated in learning processes within HS multidimensional readings. We set to demonstrate that the presence of images, particularly digital images, has a positive influence on the singular construction of hypermedia narratives; first, from their appeal and then by facilitating the thematic decentering and the access to conceptualization. From these results, we propose guidelines to be applied in didactic HS designs.

summary The links among architecture, reality and materiality have remained basically unchanged through centuries. In the present world of mediatized, artificial and global culture, the appearance of digital technologies, among others, has led these links into an irreversible crisis. This work formulates theoretical reflections on these phenomena from dimensions of analysis which involve the concepts of plurality of new spaces and plurality of new times. Besides, it recognizes that these are non- neutral processes of transformation and mutation from one mode of being to another and that they affect the practices derived from graphic-digital culture, simulation and image synthesis, and therefore the new realities they originate. Finally, it presents some provisional conclusions which characterize virtualization processes from different angles, as: (-) Deterritorialization processes. (-) Desubstantiation processes of reality. (-) Hybrid processes. (-) Innovative processes by proposing the creation of unknown spaces and chronologies, and new interaction media.

title Digital Simulation and Inferential Systems
source III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 87-92
summary From the perspective of logic and epistemological formalizations, the processes for data elaboration relate reasoning schemes to inferential operations which enable the building, understanding and setting of criteria for knowledge validation in a complex sequence. Cognitive operations do not belong exclusively to the field of discourse thinking,' they also apply to the field of perception. Specially in the area of images, there exist inferences which are expressed and operated through other media. A particular aspect is the one of digital simulation and the links established with inferential systems. Although they are not the same thing, since simulation is a cognitive methodology, both are based on similar logic principles. It is obviously necessary to build budget or referential frameworks to support practices deriving from the graphic/digital culture. Thus, they could act as judgement instruments in order to analyze and recognize changes in project, space, morphological and expressive paradigms, and to overcome the instrumental and reductionist bias usually found in the development of these practices. The present work is oriented in this direction, studying relations established among digital simulation, inferential systems, cognitive elaboration and scientific knowledge validation. We aim at exploring and researching into the affinity, links and differences between simulation and analogic-abductive inferential systems so as to characterize: 1.) The concept of digital simulation, not only due to its strong reproductive power but to its inherent referential, cognitive and poetic functions. 2.) The nature of replacing actions projected by simulation with respect to reality in order to produce a representative act the innovative and creative power of simulation, directed both to the past and the future. 3.) The dimensions of prevision and interpretation where simulation develops its theoretical and empirical attitudes and the idea that simulation derives from the combination of hypothesis and experimentation.

summary The creation can be considered as co-creation in both shared operations from interventions linked to the presence of the other. In virtual environments and interconnected in the Web, post-digital environments, these activities are provided in a unique way. Certain proyectual practices framed in Design Thinking, are stimulated by a proactive action in this direction. In particular, as in the case of Speculative Design, which explores implications of what is not reality yet, and links new technologies, scientific applications and aesthetic trends. In this direction we present teaching practices, next to Media-Labs modalities. They were realized by architecture students. They were focused in re-inserts, re-functionalizations and re-significations of the Casa del Puente, Mar del Plata, emblematic building of latin american modernism. The experience, with mostly positive result, was analyzed and evaluated according to co-creativity indicators. We conclude that these experiences rub the expressive and creative disciplinaries boundaries of Architecture career, and are close to transdisciplinar concept of Art Thinking.

summary The technology allows to center the educative process in the student. The development of the multimedia systems and Internet facilitated this change, being tools that they make possible to create an atmosphere of interactive and colaborative learning. The remote education promotes three kinds of interactions: faculty-student, students to each other and students with other dynamic electronic resources. The Histology and the Embryology are based on the study of images. We are developing to an electronic atlas of histology and embryology with pictures of histologic material captured with a digital camera and an optical microscope. The pictures (resizables and with explanatory text) are classified by tissues or systems with optative access pages and a Link to an autoevaluation multiple option type test . There is a link to an English version. The AIH makes possible an immediate access of the images and autotesting acquired knowledgements.

summary Computers have exploded into the world of the architect, yet architects have only begun to explore the role of computers in the creative process or the effects of particular applications on design projects. Likewise, educators are seeking methods for investigating the computer as a tool which may or may not effect the thing produced. Is it a tool for representation (copying), or a key player in the generation of ideas—a tool for the production of form? This paper describes the theoretical foundations and results of a series of exercises developed for beginning design students. In three investigations students consider: Algorithms (the fundamental logic of a computer application) using Building blocks (reductive entities that act as the origins of form) by Collaging and making assemblies (techniques for experimentation and exploration). The purpose of these exercises (called ABC exercises) is to explore the relationship between the computer as a tool and the production of form and type in architecture.

summary Today buildings are increasingly responsive to the weather. In such responsive buildings an “Open System” is emerging which consists of a coupling between buildings and their temporal environments. This paper assesses whether these new technologies, in addition to potentially reducing energy consumption, can also lead to a new experiential relation between building users and the weather. The paper qualitatively assesses current examples of Responsive Facades and their effect on the user’s experience of the weather. The information structures of the facade systems are then examined. From this analysis identify potential future avenues of research –or strategies – which may be most effective in making the weather apparent. Finally some design proposals which explore the possibilities of these strategies are presented. The paper is intended to complement the current, primarily technical, emphasis of research in this area by exploring the innovative architectural potential of Responsive Facades to create new user experiences and relations to the weather.

title Mathematical elements for computer graphics
source McGraw Hill, USA
summary The second edition of this classic computer graphics book represents a major rewrite. The clear concise discussion, the detailed algorithms, worked examples and numerous illustrations make the book of special interest to students, programmers and computer graphics professionals. The numerous detailed worked examples make it especially suitable for self-study. The first edition of the book, published in 1976, was one of the earliest computer graphics books. That first edition is still a staple on the bookshelves of many of the pioneers in computer graphics. The book thoroughly covers two- and three-dimensional transformations including rotation, scaling, translation, reflection, rotation about arbitrary points and axes, reflection about arbitrary lines and through arbitrary planes and points at infinity. Plane and space curves including efficient methods for representing conic sections, cubic splines, parabolically blended, Bezier and rational and non-rational B-spline (NURBS) curves are discussed. The discussion of surfaces includes surfaces of revolution, sweep surfaces, ruled and developable surfaces, Coons surfaces, Bezier and rational and non-rational B-splines (NURBS) surfaces. As with all the topics in the book, the discussion of both rational and non-rational B-spline curves and surfaces is accompanied by numerous detailed worked examples. The appendices contain over 50 pseudocoded algorithms including over 25 algorithms for Bezier and B-spline curves and surfaces.

summary In dealing with unexpected impacts of climate change current spatial planning tools are irresponsive and inflexible. The outcomes of applications of these tools are very limited in number, producing static plans that if implemented are very vulnerable to climate hazards. Therefore, an innovative generative tool has been developed to support spatial planning which results in designs that are responsive and adjustable to unexpected, simulated changes. The development of the generative tool is informed by swarm planning theory, and by contemporary generative approaches in urban design and planning. The generative tool is modeled as an Agent-Based System and utilizes versions of the canonical flocking algorithm. The agents are abstract cubical units of space that represent building envelopes. The agents exist and work within an environment that represents a site in terms of topography, land value, and available/buildable land. The agents receive information from the environment and act upon this information. The unexpected climate impact is a simulated flood, which affects both the environment and the agents. The outputs of the tool are generated 'bottom-up' in order to study emergent spatial configurations, as massings of building units.

title Towards a Digital Design Teaching Tool - A look at the ideas that should define a digital design primer

summary Architecture in the 21st century has become an increasingly complex affair. In addition to new social and cultural norms, architects are inundated with constantly changing information regarding new materials, sustainable processes, and complex building types. This state of affairs has also affected the expectations placed on architectural education. Critics (in diverse spheres) have expressed concerns about the lack of requisite skills of graduates that characterise good design thinking strategies as well as promote responsible design. It has been proposed by this author in other forums that by using digital technology to empower design learning, we can allow students to confidently use (through reading and analysis) their sketches to develop conceptual ideas that reconcile disparate elements into a habitable, environmentally friendly and architecturally responsible whole that is fit for purpose, cost effective, sustainable and a delight to clients and users. This paper will seek to discuss one of the concepts that govern such a tool. It will start by delineating the problem (discussed earlier in the abstract) before outlining the concepts or principles that a design teaching tool should adhere to. These concepts acknowledge the importance for the tool to reflect the nature of design tasks, facilitate learning and be accessible to all learning types. The paper will then focus on one concept - the nature of design tasks. The subsequent sections will describe an information structure borne from this idea and make mention of a current prototype of the tool. The paper will conclude with a discussion of the strengths of considering this concept.

summary Over the past decade, our cities have been blanketed with digital bits. Unlike the old electromagnetic, unidirectional waves, these bits are bidirectional – they communicate – and are thus tied to human activities. Our hypothesis is that by analyzing these bits we can gain an augmented, fine-grained understanding of how the city functions - socially, economically and yes, even psychologically. Some preliminary results from different projects recently carried out at MIT senseable city lab are discussed below.

summary The development of new shapes in architecture has deeply influenced the current perception of the built environment. The analysis of the processes behind this evolution is, therefore, of great interest. At least two well known factors, influencing this development, may be pointed out: the great improvement of digital tools and the tendency toward building distinctiveness.In particular, the innovation of digital tools such as parametric modeling is resulting in an overall diffusion of complex shapes, and the phenomenon is also evident in a clear expressionistic search for architectural singularity, that some might consider as a negative effect of globalization trends.Though, if we can consider as a positive result the fact that parameterization allows a deeper control over design factors in terms of reference to cultural, historical and physical context, at the same time such control possibilities are sometimes so stark to be even auto-referential, stepping over site-specific parameterization, to create unusual shapes just for the sake of complexity.The ever-growing diffusion of generative design processes is in fact going to transform niche procedures, frequently limited to temporary decontextualized structures, into an architectural complexification as an end in itself.The hypothesis of this paper is to demonstrate that site-specific parametrization can be considered as a tool able to translate intentions into shape; it is necessary, for this aim, the widening of the meaning of the word singularity.

summary This paper investigates some possibilities of interactive design in architectural practices and presents an experiment using tools for increasing dialog with people connected to the project. The building is an Art Institute in a small city of 15,000 inhabitants at Minas Gerais State, Brazil, At first, the article describes the creation of the Institute, and the important role of the architect as someone who articulates different instances in the design process, and not just the design of the object. Then, this interactive design process is described and analysed, and some differences between "Participative Design" and "Interactive Design" are emphasized. The article concludes with a discussion about the change of architect's role, changing from "designer of products" to "designer of architectural interfaces".

title Parametric Structural Design and beyond
source International Journal of Architectural Computing vol. 8 - no. 3, pp. 319-336
summary In order to directly make insightful which implications follow from structural design changes and to be able to adapt a structural design quickly to geometrical design changes made by the architect, the structural engineer may embed a parametric and associative design approach in the structural design process. This approach focuses on parametric modelling and the development of parametric tools which serve specific needs in the structural design process, allowing designers for instance to quickly communicate and discuss alternatives or to inform design team members of structural results of changing design parameters. The paper presents multiple projects within these categories of parametric approaches. They are concentrated on design and analysis with the goal of presenting practical examples of these approaches in structural design which were integrated in the full design process in order to benefit from the qualities of a multi-disciplinary parametric and associative design process.

summary By contemplating on the Eigenchair project, we ponder upon strategies and concepts of designing by using information technologies. What are the potentials of data driven design? What happens with objects when they are abstracted and reduced to a set of data? The emphasis is no longer on the creation of physical objects, but on conceiving meta-objects in the possibility space. Furthermore, this enables us to manipulate with a whole population of objects, instead of a single object. How do we get this abstract system to relate to the real world? Information technologies have opened up a number of new ways of thinking about the world and the object and they, by far, surpassed the formally simplified expression in design and architecture. Based on intellectual heritage of history and culture, information technologies can, by utilizing and recycling various elements and information, explore the 21st century object.

summary We are beyond representation; our abstract objects are symbolic; figures, fugues, faces, masks, atoms, elements, characters, avatars, indexes. It is about infusing, narrating, doping, context, information and masterful articulations. Concepts become spectrums; they live like the memory or traces of things that have been; they are not documents - they are animate. In this context interest of this paper is to see how can an image of book in the world of data be different than Kevin Lynch's systemic image of the city (Lynch 1960). Lynch has abstracted from the physical city. He is representing cities on the level of text, grammars and structures. What if one takes his exercise seriously and starts to play with text on the level on information, data, lists and indexes? What is an image of a book, its character, mood, how many faces does it have? This is a going to be a drama.

summary The colour is a protagonist in the perception phenomenon. This article shows a method to paint popular houses, based on an analogy between colours and musical notes. The colour palette is obtained by mixing chalk to a popular pigment (pó xadrez) and then establishing equivalence between these colours and a musical scale. The chromaticism is performed according to various generative criteria, one of which adopts the plant as a piano roll, proposing each unit to be painted in the colour of its corresponding note, showing that creative solutions can be achieved including colour modular coordination principles in the design process.

source Learning from the Past a Foundation for the Future [Special publication of papers presented at the CAAD futures 2005 conference held at the Vienna University of Technology / ISBN 3-85437-276-0], Vienna (Austria) 20-22 June 2005, pp. 53-62
summary A set grammar interpreter is presented in this paper. It differs from previous interpreters in many ways: it accepts any shapes for edition, the user rather than symbols, manipulates shapes, and rules can be stored and retrieved. This tool is intended as a conceptual design tool and not as a tool for full design development. The tool has been developed in the AutoLisp language as a plug-in to AutoCAD, thereby taking advantage of the existent means of visualizations.

title Can a Computer Implementation Based on Set Grammars Allow Emergent Shapes?
source Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 507-514
summary In a previous paper, (Romão 2005) it was shown that a designer could create his own rules and combine them for application in a deterministic way using a computational device based on Set Grammars called SGtools. Using this device, the designer can assess the results in a visual manner and then change the rules without any knowledge of a programming language. This work examines whether SGtools can deal with emergence by coupling the representational abilities of Set Grammars with the search power of hybrid algorithm inspired on Genetic and Taboo search algorithms. The use of this search algorithm enhances the ability of the designer to explore solutions in practical time thereby enabling him/her to find unexpected, emergent solutions.

summary This paper explores the potential of smart, moveable building components to achieve customized shading, variable privacy properties, and introduce complex visual qualities. The research combines performative design strategies and sustainable design principles, with parametric modelling and digital fabrication, within the contemporary theoretical and cultural context. The focus of this research is on architecture where physical movement is an integral part of the primary functional and formal nature of the building component. With embedded computing using input and output devices, the systems are no longer static but dynamically move and respond. The paper presents several case studies of working prototypes.

summary To stimulate all five senses through a realistic representation, audio plays a significant role. Architectural representation in digital media primarily falls in the area of visualization. Recent developments in simulation of 3d animation, lighting effect, material options and texture quality demonstrate that technology has come to a satisfactory level for representing realistic environments. But, at the same time, designers may not have paid due attention in regards to simulation of quality audio in architectural representation, particularly in 3D animation. “Surround Sound” or technically, the Dolby Digital and DTS technology has been used for entertainment purposes in film and movie production for a long time. As realistic materials and lighting increases the value of reality, sounds and sound effects too can add value to represented virtual reality architectural environments. Surround Sound technology simply delivers different signals from a 360-degree range. The reason beneath this is to break the sense of looking towards a single direction. Ideally, the audio should come from the direction of the visuals on the scene. Synchronization of both visual and Dolby Digital audio can enhance the experiential quality of an audio-visual representation. At the same time, it can break the notion of audio coming from a single direction. This paper suggests and demonstrates the technique of combining surround sound in digital 3D architectural animation for the purpose of enhancing its visual and sensory quality.

summary Recent travel forecasting models have focussed strongly upon the fact that travel is derived from the activities in which people participate, such as work, school, shopping, sport, leisure, and social events. Participation in social activities is determined by one's friends and the groups that one is a member of, i.e., their household, their workplace/school, sporting groups, voluntary organisations and clubs. These acquaintances form part of an individual's social network: a representation of the people one interacts with. This paper presents a review of the intersection between social networks and travel behaviour, identifies the key concepts, and discusses how agent-based models could be used to explore the effects of social networks on travel behaviour.

summary The theme of this presentation which is entitled 'Education in Computing & Computing in Education' is certainly of great importance in the present climate characterized on the one hand by availability of highly efficient hardware, low-cost procedures and environments which are of great interest also as far as education is concerned. Within this topic it is of primary importance to ask oneself the question 'To learn architecture with computers must students learn computers?', and should the answer be 'yes', to ask 'To what extent? What level of complexity needs to be attained in order to realize this aim? What resources need to be dedicated to the learning of computer science? Should deep involvement be necessary, at what point should we refer to a computer scientist?' In an attempt to answer these questions, it is useful to examine the state of the art within computer science vs. engineering and computer science vs. education.

summary Twenty years of revolution, from the middle '70 to the middle '90. Many things have changed since the origins of computer graphics and computer aided design in architecture. We started teaching drafting on terminals which connected to mini computers, complex procedures or sets of graphics libraries working with keywords, vectors and storage screens. The next step was devoted to the discovery of workstations in the early '80's, where the user sat face on to the whole power of a multitasking system. At that time to use up to 16 time sharing processes running on the same work station seemed to have no practical use at all. Fortunately someone (ie Xerox PARC laboratories) at the same time started to develop the so-called GUI. Graphical user interface started a revolution in human/machine interface (ie Smalltalk). The desktop metaphor, the use of multiple windows and dialogues joined with icons and pop up menus let the user manage more applications and, even more important, created a standard in application/user interface (CUA). In the meantime focus had moved from hardware to software, systems being chosen from the software running. The true revolution we have seen starting from that base and involving an ever increasing number of users was the birth of PC based applications for CAAD. Generally speaking nowadays there are three main technologies concerning teaching: communication, multimedia and virtual reality. The first is the real base for future revolution. In the recent past we have started to learn how to manage information by computers. Now we can start to communicate and share information all over the world in real time. The new age opened by fax, followed by personal communication systems and networks is the entry point for a real revolution. We can work in the virtual office, meet in virtual space and cooperate in workgroups. ATM and ISDN based teleconferencing will provide a real working tool for many. The ever increasing number of e-mail addresses and network connections is carrying us towards the so called 'global village'. The future merger between personal digital assistant and personal communication will be fascinating. Multi & HyperMedia technology is, like a part of VR, a powerful way to share and transfer information in a structured form. We do not need to put things in a serial form removing links because we can transfer knowledge as is. Another interesting and fundamental aspect typical of VR applications is the capability to change cognitive processes from secondary (symbolic - reconstructive) to primary (perceptive - motory). In this way we can learn by direct experience, by experiment as opposed to reading books. All these things will affect not only ways of working but also ways of studying and teaching. Digital communications, multimedia and VR will help students, multimedia titles will provide different kinds of information directly at home using text, images, video clips and sounds. Obviously all those things will not substitute human relationship as a multimedia title does not compete against a book but it helps.

title An Hypermedial Object Oriented Approach to Computer Aided Architectural Design

summary This paper presents a new approach to hypermedial computer aided architectural design environments. The concept is to create a whole CAAD hypermedia environment based on object oriented approach. This was probably a dream in the past but new technologies make this possible. To introduce the subject let us think to a system based on an object oriented environment, with hypermedia capabilities and dynamic creation of data structures, all these things may be managed by a single application using OLE (Object Linking and Embedding) technology provided by MS Windows. Some years ago we were waiting for a universal browser able to manage all kind of data and formats such as text, images, movies and sounds. Let us think to an object oriented file system, we can store all objects and save relations amongst them, then we can use a browsing or quering template to read and retrieve data. Three cases of study developed by Diset are discussed in this paper: HyperMedia Design Kit, De Architectura and On Line Architectural Sites Projects.

summary The research of applications concerning design, sizing and building of computer models have been, during the last years, undoubtedly of great importance and interest. Therefore, analyzing in detail the graphic packages concerning drafting and solid modelling we can undoubtedly say that these are nowadays an integral part of our daily work. In the near future, we can of course expect from those applications, new studies and research mainly concerning an easier start up and the standardization of the graphic interface; if we analyze, for example the well known package AutoCAD we can consider a new real data-base and the redesign of the interface on a graphic base (graphic choice of drawings and blocks, icons for commands, better capability of text editing, pattern editing and stretching, loading capability and visualization of various drawings in graphic windows, full compatibility with MS WINDOWS, etc. etc.). As above mentioned, these studies work on updating well known existing applications aiming to consolidate their uses; one specific section of design not yet supported by computer application is that related to the management of technical and non-technical information, nowadays still written and stored on paper.

title BioIcons
source International Conference on Generative Art
summary BioIcons are images developed with artificial life, especially modified Cellular Automata to simulate a sort of living artistic tool. Each image is a spontaneous creation of Artificial Life: different shapes and colors are assigned to each cell of the digital being; this is done linking the “biological” state of each cell and the auto similarity existing between the cell and the digital being as a whole. The resulting picture is like a microscopic view, because we can endlessly magnify portions of the image, using this process to reach, conceptually and visually, the integration between Fractals andArtificial Life. BioIcons, as the rest of my work, is the product of my programming efforts: I think that using proprietary algorithms supports autonomy and originality. I started this work studying Cellular Automata algorithms; some of them are mutations of classic Cellular Automata, others are my own creations. After that, I studied how to force the Cellular Automata to behave like an artistic tool, introducing special parameters linked with color theory, perception and auto similarity. Finally, I studied an interface in such a way to allow interaction between the artificial artists and the user, and to transform the image into an interactive and dynamic process. The dynamic interactions between the piece of art and the public, the transformation of the artistic process into something open and free and the close connections between art and investigation are the orienting ideas of my artistic effort. Yet I’m also concerned with digital technology as it should be applied to art, mainly to discover the medium’s artistic language. I consider of great importance, for my artistic development, the opportunity to integrate my strong love for nature and life with art and mathematics, with the help of computer technologies.

title Models of the design process: integrating across the disciplines
source Design Studies, Vol 12, No 4, 215-220
summary Models of the design process in engineering have converged to a consensus, represented for example by the VDI model. However, after starting from common origins, models of the design process in architectural and industrial design have diverged from the engineering consensus, in response to criticisms from both theorists and practitioners. There now appear to be significant differences between the engineering and architectural/industrial design models. Criticisms of the consensus model of engineering design have also been made, in part reflecting the earlier criticisms of architectural and industrial design models. We discuss the similarities and differences between the two consensus models -- in engineering and architectural/industrial design -- and identify prescriptive versus descriptive emphases. We suggest that attempts should be made to re-integrate the two consensus models, in order to improve education and practice across the disciplines.

title ANALYSIS AND EVALUATION OF MATHEMATICAL LEARNING STRUCTURES
source Proceedings of the Fourth International Conference of Mathematics & Design, Spetial Edition of the Journal of Mathematics & Design, Volume 4, No.1, pp. 13-21.
summary Abstract: A series of practical tasks have been done under the general name of “Surfaces in invisible cities”. Each task was based on a story taken from the book The Invisible Cities by Italo Calvino. The research carried out allows to design a pedagogical project which makes evident , generates and connects several intentions, motivations and learning structures. It proposes the use of multi- level languages and readings. Therefore, each task takes more time than that of the proposed mathematical class. Its implementation generates a broader view than that seen at the time of design.

From the detailed analysis of the results obtained, the following diverse pedagogical aspects of this work project arise: a. The use of several multiple intelligence: Howard Gardner (1985) found that a man has several distinct intelligence types among which Logical-Mathematical; Spatial; Linguistic -oriented; Musical; Intra-personal; Kinesthetic-Corporal; Interpersonal stand out. Only those types used in the task will be analyzed, making a brief description of each type. b. The architectonic-city planning aspects: architectonic-city planning interpretation of the space imagined after reading the text, with the purpose of identifying figures, shapes, volumes and colors which are expressed via an analogous space. They consist of visual, architectonic and territorial speculations without a rigorous spatial theory and it is pretended that they possess a technical precision at mathematical concept level. c. The mathematical contents: a study of the conical and square shapes present in the designs done and used in a creative manner in students’ compositions following the reading of the story chosen is carried out. An analysis of shapes is performed and mathematical problems are posed within the design context.

Traditional sketching methods have been used in task solving and the possibilities offered by the virtual tools are analyzed.

Emphasis has been put on the vertical and horizontal interchanges in the Chair, generating changes in knowledge transmission perspectives, thus allowing the sharing of contents, abilities and resources. The architectonic work imagined and created by the students will focus on these different working lines creating a harmonious and significant whole. The work is the result of multiple connections and creative proposals.

title Use Case Driven Object Modeling with UML
source A Practical Approach. Reading, MA: Addison-Wesley
summary Combining some of today's best ideas about customer-driven object-oriented design, Use Case Driven Object Modeling with UML: A Practical Approach shows you how to use Unified Modeling Language (UML) in the real world, keeping with the author's proprietary software design process. The book begins with the genesis of the author's ICONIX Unified Object Modeling Approach, borrowing ideas and strategies from the "three amigos" who invented UML: Grady Booch, James Rumbaugh, and Ivar Jacobson. Throughout this text, the ICONIX method is used to model a stock trading system, with all the relevant UML diagrams, beginning with class definition and use cases. The author's approach to software relies heavily on customer requirements and use case scenarios for which he has a good deal of practical advice. He provides numerous hints for avoiding bogged-down diagrams. After preliminary design, he advocates drilling down into specifics with robustness diagrams, which trace how classes interact with one another. The most detailed design work comes next with sequence diagrams. Subsequent chapters offer tips on project management, implementation, and testing. Throughout this lively and intelligently organized book, the author presents numerous real-world tips (and Top 10 lists) that supply wisdom to his perspective on effective software design.

summary Most foldable structures have been designed to optimize collapsibility and structural performance. Likewise, they have been solely applied to a limited number of architectural shapes such as arches, domes or geodesics. While the constant folding process between retracted and deployed states, has been the main concern of designers, non-constant transformations and the in-between states remains unexplored. This research will study non-constant transformations in the in-between states, with the aim to find novel shapes and extend the repertoire of current applications. Initially, existing structures will be modified in order to find what type of shape transformations can be produced. Finally, a novel solution, through a digital model and a kinetic physical prototype, will be proposed.

title Designing for the unpredictable: Novel model for the design of emergence through real-world behavior
source T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 847- 860
summary Most current approaches to unpredictability, within architectural discourse, lie either in the design of unbuildable emergent shapes or in performance simulations to test already designed outcomes. Even though some recent explorations have enabled the construction of emergent shapes, the unpredictability of real-world behaviors as the rules’ source for the unpredictability of shape generation remains unexplored. This paper proposes a novel model for the desig
