title	Strategic Briefing A Conceptual Process Model for Building Design
source	Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary	Nowadays building design problems are divided in partial discipline related sub-problems. Through targeted and focused attention to sub problems however the awareness of the whole is lost. Each designparticipant gives his sub-problem first priority. In contrast in the past the master builder saw the whole problem as his problem first. Thus the process of seeing the design problem as a whole, as a result ofprioritizing, considering constraints, or strategizing, is lost in today’s practice, basically because this process is a mental and implicit process, that occurred in the brain of the multi-disciplinary master builder.In most cases it is the task of no one in a design team today. The aim of this paper is modeling this conceptual mental implicit process design using System Theory and Cognitive Psychology, trying to determine the structure of the design problem as it occurs intuitively in the brain. The result will provide us with a mechanism that enables us each time to refine a unique common design problem representation. This leads to more effective use of design team capabilities, and forms an essential basis for organizing efforts toward collaborative solutions. Also some kind of clarity is provided as to how proposed solutions are to be judged.

title	Interfacing Virtual & Physical Spaces through the Body: The cyberPRINT Project
doi	https://doi.org/10.52842/conf.acadia.2002.395
source	Thresholds - Design, Research, Education and Practice, in the Space Between the Physical and the Virtual [Proceedings of the 2002 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-11-X] Pomona (California) 24-27 October 2002, pp. 395-400
summary	The cyberPRINT is a fully immersive, interactive virtual environment that is being generated in rea-timebased on physiological data readings of a human body. In other words, the cyberPRINT is based oncreating interfaces between physical and digital spaces and between biology and informationtechnologies. The cyberPRINT is also an event, wherein a performer is connected to the cyberPRINTgenerator to create a self-sustaining feedback mechanism. Although using the body to electronicallydrive music and media events is not new, most of these works have paid little or no attention to thepotential of interactive 3D virtual environments. Nor have they been so technologically advanced,interdisciplinary intensive (involving architecture, choreography, modern dance, music, bioengineering,medicine and computer science), or architecturally focused as the cyberPRINT.This project covers a wide and fertile territory that goes from the very technical and design oriented tothe very theoretical and interdisciplinary. This paper is intended to (1) expand what has been alreadypublished about this project (Bermudez et al 2000a) and (2) establish potential areas for discussionbefore and after the performance

title	Orientation Strategies within Public Spaces as the Rudiments of Space Usage and Layout” – A Workshop Contribution
source	Environmental Simulation - New Impulses in Planning Processes [Proceedings of the 5th European Architectural Endoscopy Association Conference / ISBN 3-922602-85-1]
summary	Our guiding questions in research are: - how does one orient oneself in an unknown urban space, - are there typical strategies in orientation, which become visible during the search process and finally:- do men and women orientate in the same unknown urban space in the same way or are there hints that they are following different strategies?Our long-term theme in research is to find out the regularity and the rules of the processes of moving and using public spaces. In the first step we are trying to find out in which way the individual perception of urban spaces in moving depends on the design of urban spaces. Therefore in our research design we try to explore the qualities of urban spaces which become visible in moving processes. It is one of the oldest questions of urban design and – by the way – nearly every architect or planner pretends to know everything on this subject. But nobody is yet able to predict real moving or using processes while designing. On the other side: the parameters of the material frame work are well known while moving and using processes are still nearly unknown.

title	Construction of Digital City in Physical City: Cyberspatial Cognition Approach to the Project of Hsin-Chu Digital City in Taiwan
doi	https://doi.org/10.52842/conf.caadria.2002.109
source	CAADRIA 2002 [Proceedings of the 7th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 983-2473-42-X] Cyberjaya (Malaysia) 18–20 April 2002, pp. 109-116
summary	The cyberspace upon physical space forms a new spatial structure to increase the influence on the urban fabric and the concept of space in architecture. Today, digital cities are being developed all over the world. By using a city metaphor, digital cities integrate urban information and create public spaces. How do digital cities directly connect to physical cities and become an imaginable city? Therefore, we argue that a new spatial analysis theory must be established for digital city, comparing with theories of disciplines, to find the explicitly spatial structures and relations in digital city upon physical city.

title	Perception Aspects in Underground Spaces using Intelligent Knowledge Modeling
source	Delft University of Technology
summary	The intensification, combination and transformation are main strategies for future spatial development of the Netherlands, which are stated in the Fifth Bill regarding Spatial Planning. These strategies indicate that in the future, space should be utilized in a more compact and more efficient way requiring, at the same time, re-evaluation of the existing built environment and finding ways to improve it. In this context, the concept of multiple space usage is accentuated, which would focus on intensive 4-dimensional spatial exploration. The underground space is acknowledged as an important part of multiple space usage. In the document 'Spatial Exploration 2000', the underground space is recognized by policy makers as an important new 'frontier' that could provide significant contribution to future spatial requirements.In a relatively short period, the underground space became an important research area. Although among specialists there is appreciation of what underground space could provide for densely populated urban areas, there are still reserved feelings by the public, which mostly relate to the poor quality of these spaces. Many realized underground projects, namely subways, resulted in poor user satisfaction. Today, there is still a significant knowledge gap related to perception of underground space. There is also a lack of detailed documentation on actual applications of the theories, followed by research results and applied techniques. This is the case in different areas of architectural design, but for underground spaces perhaps most evident due to their infancv role in general architectural practice. In order to create better designs, diverse aspects, which are very often of qualitative nature, should be considered in perspective with the final goal to improve quality and image of underground space. In the architectural design process, one has to establish certain relations among design information in advance, to make design backed by sound rationale. The main difficulty at this point is that such relationships may not be determined due to various reasons. One example may be the vagueness of the architectural design data due to linguistic qualities in them. Another, may be vaguely defined design qualities. In this work, the problem was not only the initial fuzziness of the information but also the desired relevancy determination among all pieces of information given. Presently, to determine the existence of such relevancy is more or less a matter of architectural subjective judgement rather than systematic, non-subjective decision-making based on an existing design. This implies that the invocation of certain tools dealing with fuzzy information is essential for enhanced design decisions. Efficient methods and tools to deal with qualitative, soft data are scarce, especially in the architectural domain. Traditionally well established methods, such as statistical analysis, have been used mainly for data analysis focused on similar types to the present research. These methods mainly fall into a category of pattern recognition. Statistical regression methods are the most common approaches towards this goal. One essential drawback of this method is the inability of dealing efficiently with non-linear data. With statistical analysis, the linear relationships are established by regression analysis where dealing with non-linearity is mostly evaded. Concerning the presence of multi-dimensional data sets, it is evident that the assumption of linear relationships among all pieces of information would be a gross approximation, which one has no basis to assume. A starting point in this research was that there maybe both linearity and non-linearity present in the data and therefore the appropriate methods should be used in order to deal with that non-linearity. Therefore, some other commensurate methods were adopted for knowledge modeling. In that respect, soft computing techniques proved to match the quality of the multi-dimensional data-set subject to analysis, which is deemed to be 'soft'. There is yet another reason why soft-computing techniques were applied, which is related to the automation of knowledge modeling. In this respect, traditional models such as Decision Support Systems and Expert Systems have drawbacks. One important drawback is that the development of these systems is a time-consuming process. The programming part, in which various deliberations are required to form a consistent if-then rule knowledge based system, is also a time-consuming activity. For these reasons, the methods and tools from other disciplines, which also deal with soft data, should be integrated into architectural design. With fuzzy logic, the imprecision of data can be dealt with in a similar way to how humans do it. Artificial neural networks are deemed to some extent to model the human brain, and simulate its functions in the form of parallel information processing. They are considered important components of Artificial Intelligence (Al). With neural networks, it is possible to learn from examples, or more precisely to learn from input-output data samples. The combination of the neural and fuzzy approach proved to be a powerful combination for dealing with qualitative data. The problem of automated knowledge modeling is efficiently solved by employment of machine learning techniques. Here, the expertise of prof. dr. Ozer Ciftcioglu in the field of soft computing was crucial for tool development. By combining knowledge from two different disciplines a unique tool could be developed that would enable intelligent modeling of soft data needed for support of the building design process. In this respect, this research is a starting point in that direction. It is multidisciplinary and on the cutting edge between the field of Architecture and the field of Artificial Intelligence. From the architectural viewpoint, the perception of space is considered through relationship between a human being and a built environment. Techniques from the field of Artificial Intelligence are employed to model that relationship. Such an efficient combination of two disciplines makes it possible to extend our knowledge boundaries in the field of architecture and improve design quality. With additional techniques, meta know/edge, or in other words "knowledge about knowledge", can be created. Such techniques involve sensitivity analysis, which determines the amount of dependency of the output of a model (comfort and public safety) on the information fed into the model (input). Another technique is functional relationship modeling between aspects, which is derivation of dependency of a design parameter as a function of user's perceptions. With this technique, it is possible to determine functional relationships between dependent and independent variables. This thesis is a contribution to better understanding of users' perception of underground space, through the prism of public safety and comfort, which was achieved by means of intelligent knowledge modeling. In this respect, this thesis demonstrated an application of ICT (Information and Communication Technology) as a partner in the building design process by employing advanced modeling techniques. The method explained throughout this work is very generic and is possible to apply to not only different areas of architectural design, but also to other domains that involve qualitative data.

title	Distributed Agents for Morphologic and Behavioral Expression in Cellular Design Systems
doi	https://doi.org/10.52842/conf.acadia.2002.111
source	Thresholds - Design, Research, Education and Practice, in the Space Between the Physical and the Virtual [Proceedings of the 2002 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-11-X] Pomona (California) 24-27 October 2002, pp. 111-121
summary	After more than a century of domination by neo-Darwinian theory, biological thought is beginning to giveincreasing recognition to developmental theory. Amongst other reasons, this recent widening ofperspective is grounded on the incompleteness of the neo-Darwinian perspective in providing modelsfor the invention of novel forms or species and individual development. Evolutionary design theory hasdrawn much of its inspiration from evolutionary biology and consequently shows analogous flaws. Thispaper demonstrates an adoption of biological developmental theory to the field of design theory in orderto fill the corresponding gap. As natural developmental processes are based on the development ofcellular units, which form composite structures, this paper employs the cellular model as a means for thedevelopment of a corresponding design and construction theory. The discussion of this approachincludes possible linkages between morphologic and behavioral attributes of tissues with implicationsfor self-assembly, growth, healing and self-reproduction of man-made structures.

title	Physical and Virtual Tools: Activity Theory Applied to the Design of Groupware
source	Computer Supported Cooperative Work (CSCW), Kluwer
summary	Activity theory is based on the concept of tools mediating between subjects and objects. In this theory, an individual's creative interaction with his or her surroundings can result in the production of tools. When an individual's mental processes are exteriorized in the form of tools - termed objectification - they become more accessible to other people and are therefore useful for social interaction. This paper shows how our understanding of activity theory has shaped our design philosophy for groupware and how we have applied it. Our design philosophy and practice is exemplified by a description of the BUILD-IT system. This is an Augmented Reality system we developed to enhance group work; it is a kind of graspable groupware which supports cooperative planning. The system allows a group of people, co-located around a table, to interact, by means of physical bricks, with models in a virtual three-dimensional (3D) setting. Guided by task analysis, a set of specific tools for different 3D planning and configuration tasks was implemented as part of this system. We investigate both physical and virtual tools. These tools allow users to adjust model height, viewpoint, and scale of the virtual setting. Finally, our design practice is summarized in a set of design guidelines. Based on these guidelines, we reflect on our own design practice and the usefulness of activity theory for design.

title	Road hierarchy and speed limits in Brasília/Brazil
source	H.J.P. Timmermans, B. de Vries (eds.) 2008, Design & Decision Support Systems in Architecture and Urban Planning, ISBN 978-90-6814-173-3, University of Technology Eindhoven, published on CD
summary	This paper aims at exploring the theory of the Social Logic of Space or Space Syntax as a strategy to define parameters of road hierarchy and, if this use is found possible, to establish maximum speeds allowed in the transportation system of Brasília, the capital city of Brazil. Space Syntax – a theory developed by Hillier and Hanson (1984) – incorporates the space topological relationships, considering the city shape and its influence in the distribution of movements within the space. The theory’s axiality method – used in this study – analyses the accessibility to the street network relationships, by means of the system’s integration, one of its explicative variables in terms of copresence, or potential co-existence between the through-passing movements of people and vehicles (Hillier, 1996). One of the most used concepts of Space Syntax in the integration, which represents the potential flow generation in the road axes and is the focus of this paper. It is believed there is a strong correlation between urban space-form configuration and the way flows and movements are distributed in the city, considering nodes articulations and the topological location of segments and streets in the grid (Holanda, 2002; Medeiros, 2006). For urban transportation studies, traffic-related problems are often investigated and simulated by assignment models – well-established in traffic studies. Space Syntax, on the other hand, is a tool with few applications in transport (Barros, 2006; Barros et al, 2007), an area where configurational models are considered to present inconsistencies when used in transportation (cf. Cybis et al, 1996). Although this is true in some cases, it should not be generalized. Therefore, in order to simulate and evaluate Space Syntax for the traffic approach, the city of Brasília was used as a case study. The reason for the choice was the fact the capital of Brazil is a masterpiece of modern urban design and presents a unique urban layout based on an axial grid system considering several express and arterial long roads, each one with 3 to 6 lanes,

summary	This paper explores the relationship between place, computation, and experience. In particular, it seeksto understand the zone that exists between the digital world on the one hand, and the physical world onthe other. It is suggested that the ideal of "immersive virtual reality", by focusing on technology systemsto replace the sensory world, misses the opportunity to explore a broader range of connections. Suchconnections involve combining physical and digital components to create blended environments. Anumber of examples of such environments are examined. The term "blended reality" is proposed todescribe such digitally augmented physical environments and to distinguish between them and virtualenvironments or cybrids. A design studio series formed around the exploration, design and experienceof blended physical and digital spaces is described and selected results presented.

title	Descriptive Conventions for Shape Grammars
doi	https://doi.org/10.52842/conf.acadia.2002.365
source	Thresholds - Design, Research, Education and Practice, in the Space Between the Physical and the Virtual [Proceedings of the 2002 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-11-X] Pomona (California) 24-27 October 2002, pp. 365-378
summary	This paper introduces a new set of descriptive conventions for shape grammars, and illustrates howthey can be used to address problems with user experience. The shape grammar formalism has beenshown to be capable of generating designs such as Palladian villas, Prairie houses and Queen Annehouses. The formalism can describe the process to develop a design through the use of rules, symbols,and lines.The user’s experience in applying the rules is often neglected in the design of the grammars. Thiscreates four problems: 1) the user is unaware of the implicit sequencing of rules, 2) the user cangenerate invalid design states, 3) the user is forced to apply technical rules that do not change theoverall design, and 4) the user is only given a restricted set of design choices.To address these problems, a new set of descriptive conventions has been developed that provides alayer of abstraction built on top of the formalism. These conventions are currently being implementedusing the Visual LISP programming environment in AutoCAD. The program applies rules, whichincorporate the use of the new conventions, to produce a design.The conventions are based on two techniques. The first technique is an explicit control mechanism thatdetermines the sequencing of rules based on the success or failure of a rule application. Becausesome design changes require more than one rule, this allows the grammar to chain a sequence of rulesto create macros since. The second technique is a mechanism that demarcates an area of the drawingfor query. With this technique, a rule is able to recognize void spaces in a drawing.A comparison of the rules to construct a bi-laterally symmetrical grid in three grammars--Palladian,Yingzao Fashi, and Grid--will be used to demonstrate the advantages of the new conventions.

summary	This research is producing digital cartographic models of the urban space of Rome, NY. Workingbetween two software packages for spatial visualization that are now ubiquitous in architecture (FormZ)and geography (ArcView), the project takes an interdisciplinary approach to understanding howavailable data sources and modes of visualization enable or discourage particular understandings ofurban space. The project is designed specifically to work within, and develop, a critique of theconstraints of the two software packages. Rather than encouraging a deceptively smooth integration ofwhat may be fundamentally incommensurable forms of knowledge, this project begins with the premisethat vocabularies and conceptions of space vary considerably in various disciplines, as do the modes ofvisualization that each has developed to represent, document, examine, and produce space.

summary	Architectural design has relevance to the design of virtual worlds that create a sense of place throughthe metaphor of buildings, rooms, and inhabitable spaces. The design and implementation of virtualworlds has focused on the design of 3D form for fast rendering to allow real time exploration of theworld. Using platforms that were originally designed for computer games, some virtual worlds nowcontain preprogrammed interactive behaviors. We present an agent model of virtual worlds in which theobjects in the world have agency, that is, the objects can sense their environment, reason about theirgoals, and make changes to the environment. This agent model is presented and illustrated using a wallagent. Following from the wall agent, we generalize how agency can be attached to any 3D model in avirtual world.

title	BEYOND ANALYSIS AND REPRESENTATION IN CAD: A NEW COMPUTATIONAL APPROACH TO DESIGN EDUCATION
source	Submitted to the Department of Architecture in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the field of Architecture: Design & Computation at the Massachusetts Institute of Technology
summary	This thesis aims at changing students' attitude towards the use of computer-aided design (CAD) in architecture. It starts from the premise that CAD is used mostly for analysis and representation, and not as a real design aide, and that architecture students have a bias against learning computer programming. For this purpose, a prototypical instruction system that mixes computer-aided design and computational design theory was developed, based on a series of fundamental concepts that are common to both fields. This system was influenced by Mitchell's (1987) The Art of Computer Graphics Programming and Stiny's (1976) shape grammars. Despite being based on solid theoretical foundations, CAD has progressively become an exclusively practical tool, since its origins in the 50's and 60's, while computational design theories have been mostly restricted to the academic circles. This thesis proposes an inversion in the present situation: the study of CAD theory, and the application of computational design into practice. The system proposed provides a conceptual framework that can be adapted to different circumstances, including course formats and resources, as well as students' background and technical training. It is based on seven fundamental concepts from computational design theories that are also important to the study of shape grammars: symmetry, recursion, rule-based compositions, parameterization of shapes, generative systems, algorithmization of design procedures, and shape emergence. These concepts are introduced within a CAD context, where their practical implementation and experimentation are possible, focusing the understanding of the computational nature of design. During this research, the proposed system was tested in two case studies with students from schools that had contrary orientations in terms of the importance of CAD in the architectural curriculum. In these experimental courses, students' activities evolved from using a commercial CAD tool in an innovative way, to the use of programming techniques for creating meaningful tools. Despite not having a statistical reach, the fieldwork allowed drawing preliminary conclusions about the proposed system's efficacy, since virtually all the students reported changing their understanding of the role of CAD in architecture, while some also acknowledged a conceptual influence in other subjects and in the way they see architecture.

summary	This paper presents a new mechanism to access and interact with DYNAMO, a collective case base for architectural design developed as a Web-based tool. The system is fully operational since a few years in the context of architectural design education as well as for seminars on architectural theory. We have now developed a set of visual keys structured at the one hand according to the Vitruvian tripartition of architecture: Firmitas (structure, materials,…), Utilitas (building programme,…), Venustas (formal qualities/articulation, spatial configuration,…) to which we added Context (topography, site, budget, climate,...) as a supplementary dimension, and at the other hand including three levels of detail: single spaces, building blocks or master plan entities. Visual keys match the architect’s designerly way of thinking. The visual keys are in fact nothing else than a graphical codification of architecture within the realm of architectural composition. The software, that has been developed so far, does not only allow users to access cases via the keys we have implemented, but it also provides a tool to sketch and submit their own keys.

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

summary	This paper reports on our experiences using computer graphic visual simulations to encouragearchitecture students to examine daylighting aspects of their design solutions during conceptual stagesin undergraduate design studios. Using computers for conceptual design was the major thrust of theinvestigation of these studios where daylight was one of the issues students examined for a four-weekperiod. We present our experiences and student work with traditional CGI-based and physics-basedradiosity rendering techniques. Our experiences show that although radiosity based visual simulation iscapable of producing more realistic images, in the design process its success was limited to studyingclearly defined interior spaces. CGI-based visualization, particularly when used in conjunction withtraditional physical models, was more useful and effective in the design process, being closer to thefluid nature of the design process. Further work needs to be done to make the currently availableradiosity-based software suitable for use in the design decision-making process.

title	Time-like Architectures: The Emergence of Post-spatial Parametric Worlds
doi	https://doi.org/10.52842/conf.acadia.2002.069
source	Thresholds - Design, Research, Education and Practice, in the Space Between the Physical and the Virtual [Proceedings of the 2002 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-11-X] Pomona (California) 24-27 October 2002, pp. 69-76
summary	A new trend is emerging in architecture today: dynamic and time-like architectures (term derived fromthe language of Theory of Relativity) that are capable of moving, flexing and reconfiguring themselvesthrough globally networked control mechanisms are emerging. Such buildings maybe "pluggedinto" the information networks and can be manipulated through remote interaction. Architecture canbe published, literally. At this time there is no one theoretical framework available to address sucharchitectural efforts and the paper is aimed at providing a framework under the rubric of "TimelikeArchitectures". The paper addresses the unprecedented transformation of the spatial and temporalfoundations of architecture by a convergence of two technological developments: global real-timeinformation networks and kinetic, pneumatic tectonics. Envisioned and in some cases built by agroup of avant-garde architects, time-like architectures are poised to become a norm in a nottoo distant future. The paper will identify, define and outline few time-like works. The paper willalso outline the historical, theoretical and ethical relationships between post-spatial (authors term),post-modern and modern architectures using Charles Jencks’ structuralist classification,Evolutionary Tree.

title	Digital Surface Representation and the Constructability of Gehry’s Architecture
source	PhD Thesis MIT, Cambridge, MA
summary	This thesis presents work in the development of computational descriptions of Gehry’s architectural forms. In Gehry’s process for realizing buildings, computation serves as an intermediary agent for the integration of design intent with the geometric logics of fabrication and construction. This agenda for digital representation of both formal and operational intentions, in the context of an ongoing exploration of challenging geometries, has provided new roles for computation in architectural practice. The work described in this thesis focuses on the digital representation of surface geometry and its capacity for describing the constructibility of building enclosure systems. A particular class of paper surface forms – curved surfaces with minimal in plane deformation of the surface material – provide the specific object of inquiry for exploring the relationships between form, geometry and constructibility. An analysis and framework for the description of Gehry’s geometry is developed through existing theory of differential geometry and topology. Geometric rules of constructibility associated with several enclosure system strategies are presented in this framework. With this theoretical framework in place, the discussion turns to efforts to develop generative strategies for the rationalization of surface forms into constructible configurations.

title	Conception of Urban Space – Simulators Supporting Planning Work
source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 87-90
summary	Experimenting with “space”, joint exploring solution possibilities with all those concerned and the anticipation of the future involving as little risks as possible are important functions of space-related simulation contributing to increasing of knowledge, decision-finding and communication throughout the planning process. Questions as to conception of urban space, the modeling of urban volume and urban design, the improvement of spatial match (“fit”) and workability regarding utilization (”fitness for use”) call for suited simulators supporting planning work. All planning phases of urban-spatial planning processes are to benefit thereby: understanding is promoted, spatial characteristics developed, preservation- and renewal priorities are deduced, variants are conceived, spatial impact analysis of spatial ideas and graphic communication are to act as basis fordecision-finding. The present contribution also discusses the application possibilities of the “CAVE” (space with threedimensional image projections) as planning tool. The following questions are to be covered: qualitative and quantitative aspects of modeling of urban space, planning benefits arising from differing “levels of details” (LOD’s), “navigation in” and “interaction with urban spaces”, testing in line with requirements and examples of planning practice as well as current research- and development needs.

title	Theoretical Perspectives For The Development Of 3D City Models In Architectural Education
doi	https://doi.org/10.52842/conf.ecaade.2003.247
source	Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 247-252
summary	This paper continues the discourse of the round table session of eCAADe 2002 on the problems of existing digital city models. It reviews recent papers on the subject, suggests criteria for the improvement of digital city models, and points out some applications for a broader base of users, and particularly in the field of architectural education. it is suggested here that the design professions of architecture and urban design should be more comprehensively included by broadening the approach to 3dcms. Changes in contemporary architectural, urban planning and design theory, collaborative design practice and constructivist education, lead us to suggest a change of emphasis from 2D urban planning principles to those of 3D urban design and morphology.
