title	Producción colaborativa de material de enseñanza-aprendizaje de Gráfica Digital con aportes multidisciplinarios [Collaborative production for taught-learning materials for digital graphic with multidisciplinary contributions]
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 117-121
summary	For a contribution to problem solving processes at different areas, this paper presents the use of Digital Graphics as a knowledge object for a distance teaching/learning workshop. At the Learning Management System, different theoretical subjects with supporting tools were proposed, and exercises requiring collaborative work. An specific didactic situation using available technologies at Internet for 3D modelling, combined with satellite images and geographic information program was proposed. The final works were then shared by a 3D models repository. As a complement of this experience and in relation with their professional work, every student proposed a new didactic situation including Learning Objects, sharing them with the others members of the group, through conceptual maps built up in a co-operative way.

title	Structural Performance Modelling in Architectural Design Education
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	In architectural education the process of design has evolved with the development of CAD technology. In many design schools throughout the world, the computer has extended its role beyond that of a drafting machine to become a tool for performance modeling. Applications currently used by students test lighting, thermal conditions, and structural validity, to name a few. However the goals in education are not identical to those in practice, and digital modeling can support learning in many ways that are not particularly useful or appropriate in professional practice. In the design of structures there are three fundamental levels of understanding: behavior, form, and performance. Each has its place in design education and uses digital modeling in different forms. This paper describes various pedagogical models that incorporate computer aided drawing and performance modeling in the teaching of structures. Examples of student exercises and projects are discussed.

title	Parametric Modeling as a Design Representation in Architecture: a process account
source	Third CDEN/RCCI International Conference on Education, Innovation, and Practice in Engineering Design, Toronto, ON, Canada, 24-26 July 2006. Canadian Design Engineering Network. Published on CD.
summary	Disciplines outside of engineering, for instance, architecture, are adopting parametric modelling as a design representation. This paper reports on three aspects of the adoption process, which is largely being conducted through multi-day workshops outside of formal university course settings. Fist, the structure and process of such workshops may be a model for interdisciplinary learning and university-industry liaison. Second, students learning parametric modelling must master skill different from that required for non-parametric representation. Third, the parametric modelling strategies being developed in architecture may have both similarities and differences to those used in engineering.

summary	Learning Management Systems (LMS) embody spaces that combine Virtual Classrooms, learning communities, repositories of educational resources and communication devices. The use by faculty members and students, in a campus containing the schools of Architecture, Design and Geography, of Open Source LMS MOODLE, during the years 2005-2006, was assessed. An analysis of the Digital Vestiges, the metadata in the logs database, distinguished between the levels of informative and communicational interaction. The results draw attention to a trend, similar to previous measurements in Latin America, of more use of ICT educational resources for informational purposes than communicational interactions between teachers and students.

summary	Automated recognition of sketch drawings can provide the means for a natural interface between the designer and a design support system. Sketch drawing recognition is knowledge-intensive in the sense that the system must know what to look for in a drawing. In earlier work, we identified 24 different types of representations, termed graphic units. For recognition of graphic units we combine a multi-agent approach and online recognition. Each agent is specialised for one graphic unit. It continuously parses the online input stream for stroke features that fall within its scope. When an agent-specific threshold is reached, the agent puts a claim. Each agent has a specific cluster of features that can be viewed as distributed over a decision tree. The activation pattern of feature clusters over the decision tree is an indication which graphic unit is likely to be identified by the system. In this paper, we present the exhaustive set of features for agents and a binary decision tree over which the features are distributed.

title	Sensor-based Aware Environment
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	This paper provides an overview of the requirements for a computational model of a Sensor-Based Aware Environment (SBAE) that integrates sensor technologies with the Building Information Modelling (BIM) in order to sense ambient and physical aspects of the built environment. Wireless sensors sense ambient data of a built environment, process, and communicate these data through an ad-hoc wireless network. The BIM, on the other hand, is based on International Foundation Classes (IFCs) and contains data about the physical infrastructure (i.e. Walls, Windows, doors) and abstract entities (i.e. Spaces, Relationships) and relationships between those entities. Therefore, the proposed computational model could sense real time data that are related to the as-built information model allowing for holistic building state information.

source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 656-663

summary	Representational approaches have always played an important role in the design-driven development of built environments, the analytical study of architectural compositions and their effects. With the introduction – and successive steady development – of computer-based platforms of visualization, the professional and intellectual palette of designers, as well as researchers, have expanded considerably. Nonetheless, in recent years the opportunities for systematic scrutiny and understanding of the expressive qualities of design proposals and artefacts have all too frequently been overshadowed by high-flying conceptual developments and seductive representation modes. It is time that the objective description and unravelling of architectural compositions – so to speak the discipline of Ekphrasis in design practice, education and research – is once again given more prominence in architectural discourse and debate. The central idea behind this contribution is that, by linking instruments of design with the methods of formal composition and decomposition, renewed opportunities for representation-driven study in a scholarly context, focusing upon elusive compositional attributes and their workings, may be given a new impulse. The project that is presented here concerns a case-based explorative study into the domains of aesthetic convention and invention, making use of a variety of virtual and physical representation techniques. These include digital as well as tangible modelling and sketching approaches (separately and in combination), in conjunction with computer-based image manipulation techniques, making use of systematic data identification and denotation. The opportunities, merits and shortcomings of the computer-based and physical visualization approaches, which were applied and tested, are discussed on the basis of results and findings from the ongoing AA Variations project.

source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 258-262
summary	Based on study of recent projects develop by reputed architectural firms, this paper reviews the role of digital techniques in the conception of design, describing mainly the proposals for Philarmonic Orchestra of Copenhagen by Jean Nouvel and the Harbour of Tenerife by Herzog and De Meuron, Both projects state innovative architectural concepts with diverse graphic resources. Digital media is not used as a specific tool, but as an integrated repertoire related to design issues, Image processing, photo-collages, 3D modelling, renderings, colored layouts and graphic sequences are applied to explore novelty shapes, spatial qualities, functional arrangements and constructive strategies. In these cases computer technologies are participating in design generation supporting overall architectural creativity. In order to benefit from new design media that approach express the relevance of firms' culture related to innovation and development (I+D).

summary	This research presents the new orientation of the combination of digital modelling with generative programming and joint method of traditional wood structure for manipulating Rapid Prototyping to explore the assembling of free form objects. The presenting of the example indicates that the edition of Maya scripts defines the purpose of design. Through the discussion on scripts developing the assembly of the free-form objects of frames and surfaces and through the achievement that RP produces and examines objects, we bring out the possibilities of the new form developed from the old structure and illustrate how to develop our hypothesis. The developed result could provide the possible new way for free-form assembly. We expatiate our research process and final achievement and provide a new thinking direction in the education field.

title	The Digital Design Process: reflections on architectural design positions on complexity and CAAD
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	These instructions are intended to guide contributors to the Second Architecture is presently engaged in an impatient search for solutions to critical questions about the nature and the identity of the discipline, and digital technology is a key agent for prevailing innovations in architectural design. The problem of complexity underlies all design problems. With the advent of CAD however, Architect’s ability to truly represent complexity has increased considerably. Another source that provides information about dealing with complexity is architectural theory. As Rowe (1987) states, architectural theory constitutes “a corpus of principles that are agreed upon and therefore worthy of emulation”. Architectural theory often is a mixed reflection on the nature of architectural design, design processes, made in descriptive and prescriptive terms (see Kruft 1985). Complexity is obviously not a new issue in architectural theory. Since it is an inherent characteristic of design problems, it has been dealt with in many different ways throughout history. Contemporary architects incorporate the computer in their design process. They produce architecture that is generated by the use of particle systems, simulation software, animation software, but also the more standard modelling tools. The architects reflect on the impact of the computer in their theories, and display changes in style by using information modelling techniques that have become versatile enough to encompass the complexity of information in the architectural design process. In this way, architectural style and theory can provide directions to further develop CAD. Most notable is the acceptance of complexity as a given fact, not as a phenomenon to oppose in systems of organization, but as a structuring principle to begin with. No matter what information modelling paradigm is used, complex and huge amounts of information need to be processed by designers. A key aspect in the combination of CAD, complexity, and architectural design is the role of the design representation. The way the design is presented and perceived during the design process is instrumental to understanding the design task. More architects are trying to reformulate this working of the representation. The intention of this paper is to present and discuss the current state of the art in architectural design positions on complexity and CAAD, and to reflect in particular on the role of digital design representations in this discussion. We also try to investigate how complexity can be dealt with, by looking at architects, in particular their styles and theories. The way architects use digital media and graphic representations can be informative how units of information can be formed and used in the design process. A case study is a concrete architect’s design processes such as Peter Eisenman Rem Koolhaas, van Berkel, Lynn, and Franke gehry, who embrace complexity and make it a focus point in their design, Rather than viewing it as problematic issue, by using computer as an indispensable instrument in their approaches.

title	A Computational Approach to the Reconstruction of Surface Geometry from Early Temple Superstructures
source	International Journal of Architectural Computing vol. 3 - no. 4, 471-486
summary	Recovering the control or implicit geometry underlying temple architecture requires bringing together fragments of evidence from field measurements, relating these to mathematical and geometric descriptions in canonical texts and proposing "best-fit" constructive models. While scholars in the field have traditionally used manual methods, the innovative application of niche computational techniques can help extend the study of artefact geometry. This paper demonstrates the application of a hybrid computational approach to the problem of recovering the surface geometry of early temple superstructures. The approach combines field measurements of temples, close-range architectural photogrammetry, rule-based generation and parametric modelling. The computing of surface geometry comprises a rule-based global model governing the overall form of the superstructure, several local models for individual motifs using photogrammetry and an intermediate geometry model that combines the two. To explain the technique and the different models, the paper examines an illustrative example of surface geometry reconstruction based on studies undertaken on a tenth century stone superstructure from western India. The example demonstrates that a combination of computational methods yields sophisticated models of the constructive geometry underlying temple form and that these digital artefacts can form the basis for in depth comparative analysis of temples, arising out of similar techniques, spread over geography, culture and time.

title	Physical or Digital:Alternative Approaches to Modelling for a Participatory Design Environment
source	International Journal of Architectural Computing vol. 4 - no. 4, pp. 57-70
summary	Many of those who are advocating the use of computers in planning and design are promoting the internet as a way of involving non-experts. Although there is a great deal to be said for such an approach, the role of direct face-to-face communications remains important and yet relatively little has been done to investigate how computers can be of assistance in such a setting. This paper will present the results of an experiment in which a commercially available, but relatively inexpensive, computer-aided architectural design (CAAD) package has been used to facilitate participatory design. The results indicate that such an approach can significantly improve the quality of design and also enhance the experience of those who have participated in the design process.

summary	Simulating the development and the image of architecture and urban design means to show how the environment of the future and the living conditions could develop. At the same time it is part of our task to explain our work to local people and to the public and to passion skills in methods, instruments and knowledge in planning to the next generation of architects, planners and last but not least to discuss and to renew them once more for ourselves. Our aim was also to reflect what we have done since starting the look through the key-hole of endoscopy. Meanwhile this look has been completed since the beginnings in 1993 much more by computer and monitor. It is not the question to take the endoscope or the computer as a methodical and instrumental approach. Nowadays we normally decide to take the endoscope and the computer. In preparing the conference and the workshop we thought that this should now also be the moment not only to inform each other and the participants on methods, tools and best practices in simulating and designing the environment but also to focus on the social and human consequences of perception, movement and use the present urban spaces and the urban space in future. So we proposed the theme “MOTION, E-MOTION and URBAN SPACE” and we invited a scientific expert in experimental psychology to give us some serious reflections and one or another hint on our research themes and methods. The contributions and discussions in the conference showed that the proposal has not only been accepted but has also been completed and enriched especially concerning the theme urban space, it’s processes of usage and it‘s atmosphere. Also in the themes of endoscopy and the research on modelling urban spaces and architecture, meanwhile nearly “traditional” ones, remarkable results were presented and discussed. A very important point of contributions and the following discussions was how to present our subjects to the interested public and to improve our own internal exchange. An object could be to enforce the research tasks in researching together even more.

title	MultiCAD – MOGA A System for Conceptual Style Design of Buildings
source	Conference Proceedings of the 9th 3IA (2006) International Conference on Computer Graphics and Artificial Intelligence, p73-84
summary	The synthesis of the three-dimensional morphology of a building is one of the most important tasks in architecture. Space planning and morphology are of the most interesting and complex of architectural design problems. Architectural design is guided by the constraints on the spatial composition and the morphology of the final building. During the conceptual phase problems are characterised by fuzziness and complexity. Building requirements are ill-defined and contradictory. The designer should explore the solution space for alternative building solutions while refining requirements and style preferences. In this paper we present the development and implementation of an Evolutionary Declarative Design system prototype for the aid of conceptual style design of buildings. The system is a specific MultiCAD prototype system including architectural knowledge, architectural style and a multi-objective genetic algorithm. Two design cases are presented for two different architectural styles. The applicability and efficiency of the system prototype are discussed.

summary	The choice of a chord and its execution should be regarded as a must and not left to arbitrary wish or superficial speculation. (Johannes Itten, 1961) The paper describes a modular concept for the IT-support of planning practice using BIM (Building Information Modelling) and a parameterized building model. The platform used is the modularized software concept for architectural planning in existing built contexts (prototype software FREAK). The current progress in the development of a reasoned support of planning tasks is described in this paper in more detail. The system consists of a series of software prototypes which are linked to the BIM, utilize the specific data within and demonstrate the value of a consistent and extendable CAD-model. The “Colored Architecture” software prototype is one such design-support module of the software platform and enables the designer to experiment with the parameters colour, light and materials in architectural space. This module supports experimentation, assessment and realization of colours and materials in the architectural design process on a new quality. For instance, the integration of “live radiosity” light simulation allows a qualified and interactive assessment and evaluation of colours and materials in near-real lighting conditions. The paper also details further software prototypes, modules and concepts including building surveying and the design of self-supporting domed structures.

title	Generation of alternative designs in architectural problems using Shape Grammars defined with animation tools - A computer implementation of shape grammars using modelling and animation software
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 302-307
doi	https://doi.org/10.52842/conf.ecaade.2006.302
summary	We present a model of generation of alternative designs to selected architectural and spatial configurations of small complexity. Specifically we present a production pipeline of architectural / spatial configurations using the context of animation and time based design tools. Our model consists of time and space design constraints of boundaries / objects affecting a given architectural design, thus producing an alternative solution for every timeframe of the animation cycle. The alternative designs vary from the original according to their temporal and/or spatial distance from the original object on the animation time-line. The constraints placed upon the objects , used as actuators of Shape Grammars, are defined informally by the user/designer while their influence can vary according to time, speed, location, configuration of the object and/or the constraint itself. However the constraints further function as formal rules for the Shape Grammar creation so that our model tries to predict ahead of time the emergence of alternate designs. The employ of animation tools [shape driven curves, speed and time-line functions,parent child relationships] in the shape generation of our model empowers the user/designer to configure whole sets of shapes and designs interactively and without the need to define every solution independently. Simultaneously, a different, time-focused view of our model describes its use on designs that develop different configurations over time. Thus a duality of our model is established: either the animated schema may be a sum or family of various designs or the animated time-line represents a single design which changes over time. Finally the possibility of an automated analysis of every design is discussed, using Space Syntax diagrams so the designer can quickly evaluate the various spatial configurations produced by a single original.

summary	Subject of study is the possible organisation of the Olympic Games of 2028 in the Netherlands, as seen from an urban development viewpoint. The project focuses on the decision-making process in the initiative phase. Aim of the project is the development of a decision support tool for the complex, interdisciplinary decision-making process which should result in an optimum interorganisational design. The methodology used to find the optimum choice is the combination of sub-solutions. Preference Measurement modelling based on a multi-criteria decision analysis is the technique employed. The group decision is a choice out of a number of Olympic urban development combinations, which is made in such a way that the preferred combination is the 'best' among the possible candidates for all relevant stakeholders.

summary	In this paper, we present a method that allows designers to interactively create partially self-similar manifold surfaces without relying on shape grammars or fractal methods. The modellers that are based on traditional fractal methods or shape grammars usually create disconnected surfaces and restrict the creative freedom of users. In most cases, the shapes through conventional fractal or shape grammar methods are defined by hard coded schemes that allow limited interactivity for the design process. We present a new approach for modelling such shapes. With this approach, we have developed a simple generative tool with given adjustable parameters to achieve variety of conceptual forms. Using this tool, designers can interactively create a variety of partially self-similar manifold surfaces.

title	Evolving Urban Structures using Computational Optimisation
source	Proceedings of the Generative Arts conference, Milan, 2006
summary	This paper investigates the use of computer analogies for naturally inspired optimisation techniques as an aid to developing the site layout and massing for the new World Trade Centre development in Pristina Kosovo, which is being designed and developed by 4M Group architectural company, in conjunction with the Advanced Modelling Group Aedas. The development of a genetic algorithm will incorporate various techniques, that have been developed in the field of multi-objective optimisation, to create three dimensional massing models, and site layout solutions which partially fulfil the Prisina brief requirements, which are taken from specifications created by 4M Group. Genetic algorithms are based on natural evolutionary principles which are explained in this paper. It will incorporate Pareto concepts to manage the optimisation of the various objective functions. For example, these will include volume and position of units, which will ensure that the different and sometime conflicting needs of the site are balanced throughout the optimisation. This type of problem is often known as an NP-complete (non-determinate polynomial time) problem. This will provide architects and planners with a number of Pareto optimised site massing solutions as an aid to the design process. An initial investigation into the specifics of the Pristina site requirements, will be followed by an investigation into the the genetic algorithm which is created in Visual Basic for Applications (VBA) linked with AutoCAD as the graphical output of the code. The embryology (development) of the various solutions from the genetic information incorporates an ‘ant’ pheromone trail model, which simulates the action of ants during food foraging, as a tool for initial route planning within the site. Diffusion and cellular automata are used during the development of the solution to construct the massing for the site.
