title	A strategy for complex-curved building design:Design structure with Bi-lateral contouring as integrally connected ribs
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 465-469
summary	Shapes in designs created by architects such as Gehry Partners (Shelden, 2002), Foster and Partners, and Kohn Peterson and Fox rely on computational processes for rationalizing complex geometry for building construction. Rationalization is the reduction of a complete geometric shape into discrete components. Unfortunately, for many architects the rationalization is limited reducing solid models to surfaces or data on spread sheets for contractors to follow. Rationalized models produced by the firms listed above do not offer strategies for construction or digital fabrication. For the physical production of CAD description an alternative to the rationalized description is needed. This paper examines the coupling of digital rationalization and digital fabrication with physical mockups (Rich, 1989). Our aim is to explore complex relationships found in early and mid stage design phases when digital fabrication is used to produce design outcomes. Results of our investigation will aid architects and engineers in addressing the complications found in the translation of design models embedded with precision to constructible geometries. We present an algorithmically based approach to design rationalization that supports physical production as well as surface production of desktop models. Our approach is an alternative to conventional rapid prototyping that builds objects by assembly of laterally sliced contours from a solid model. We explored an improved product description for rapid manufacture as bilateral contouring for structure and panelling for strength (Kolarevic, 2003). Infrastructure typically found within aerospace, automotive, and shipbuilding industries, bilateral contouring is an organized matrix of horizontal and vertical interlocking ribs evenly distributed along a surface. These structures are monocoque and semi-monocoque assemblies composed of structural ribs and skinning attached by rivets and adhesives. Alternative, bi-lateral contouring discussed is an interlocking matrix of plywood strips having integral joinery for assembly. Unlike traditional methods of building representations through malleable materials for creating tangible objects (Friedman, 2002), this approach constructs with the implication for building life-size solutions. Three algorithms are presented as examples of rationalized design production with physical results. The first algorithm [Figure 1] deconstructs an initial 2D curved form into ribbed slices to be assembled through integral connections constructed as part of the rib solution. The second algorithm [Figure 2] deconstructs curved forms of greater complexity. The algorithm walks along the surface extracting surface information along horizontal and vertical axes saving surface information resulting in a ribbed structure of slight double curvature. The final algorithm [Figure 3] is expressed as plug-in software for Rhino that deconstructs a design to components for assembly as rib structures. The plug-in also translates geometries to a flatten position for 2D fabrication. The software demonstrates the full scope of the research exploration. Studies published by Dodgson argued that innovation technology (IvT) (Dodgson, Gann, Salter, 2004) helped in solving projects like the Guggenheim in Bilbao, the leaning Tower of Pisa in Italy, and the Millennium Bridge in London. Similarly, the method discussed in this paper will aid in solving physical production problems with complex building forms. References Bentley, P.J. (Ed.). Evolutionary Design by Computers.

title	Applying Genetic Algorithms to Establish Disaster Decision Support System for Flooding Evacuation Path of Hsichih Area in Taiwan
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Developments in Design & Decision Support Systems in Architecture and Urban Planning, Eindhoven: Eindhoven University of Technology, ISBN 90-6814-155-4, p. 63-75
summary	Because of the special geography features and subtropics weather in Taiwan, we need to provide correct information to help people making decision when they are in disaster. So the disaster decision support system must offer proper information of evacuation path to people. This research has shown the difficulties associated with the GIS and the flooding evacuation path search through the huge searching space generated during the network analysis process. This research also presents an approach to these problems by utilizing a search process whose concept is derived from natural genetics. Genetic algorithms (GAs) have been introduced in the optimization problem solving area by Holland (1975) and Goldberg (1989) and have shown their usefulness through numerous applications. We apply GA and GIS to choice flooding evacuation path in metropolitan area in this study. We take the region of Shiji city in Taiwan for case. Firstly, we establish the node relationship of GA calculation, the level of the weight is the standard of the date that is exported by Disaster Database. Secondly, we apply GA to calculate different evacuation path in different time series. Finally, we build the model of choosing flooding evacuation path.

title	What’s Happening to Architectural Sketching? - Interviewing architects about transformation from traditional to digital architectural sketching as a communicational tool with clients
doi	https://doi.org/10.52842/conf.ecaade.2022.1.389
source	Pak, B, Wurzer, G and Stouffs, R (eds.), Co-creating the Future: Inclusion in and through Design - Proceedings of the 40th Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2022) - Volume 1, Ghent, 13-16 September 2022, pp. 389–398
summary	The paper discusses 23 interviewed architects in practice about the role of traditional and digital sketching (human-computer interaction) in communication with the client. They were selected from 1995 to 2018 (the interval of graduation) from three different countries: the Czech Republic (CR), Slovakia (SR), Netherland (NR). To realize three blending areas that impact the approach to sketching: (I) Traditional hand and physical model studies (1995-2003). (II)Transition form - designing by hand and PC (2004–2017). (III) Mainly digital and remote forms of designing (2018–now). Interviews helped transform 31 “parameters of tools use” from the previous theoretical framework narrowed down into six main areas: (1) Implementation; (2)Affordability; (3)Timesaving; (4) Drawing support; (5) Representativeness; (6) Transportability. Paper discusses findings from interviewees: (A) Implementation issues are above time and price. (B) Strongly different understanding of what digital sketching is. From drawing in Google Slides by mouse to sketching in Metaverse. (C) Substantial reduction of traditional sketching (down to a total of 3% of the time) at the expense of growing responsibilities. (D) 80% of respondents do not recommend sketching in front of the client. Also, other interesting findings are further described in the discussion.

summary	At the last conference we emphasized, that the presentation had to transport the whole project. This time we will present adequate methods of computer aided spatial simulation in education and practice that promote spatial imagination in the design process and the suggestive power of a presentation, while we still bear in mind the unity and the reciprocal influence of the design process and the presentation, that is spatial imagination and spatial simulation. Working on the computer first of all means to choose the appropriate software tool to exploit different aspects of specialized software from mathematical constructions to emotional experiences and from interaction to immersion.

title	A computer Based System for the Design and Fabrication of Tensegrity Structures
doi	https://doi.org/10.52842/conf.acadia.2004.100
source	Fabrication: Examining the Digital Practice of Architecture [Proceedings of the 23rd Annual Conference of the Association for Computer Aided Design in Architecture and the 2004 Conference of the AIA Technology in Architectural Practice Knowledge Community / ISBN 0-9696665-2-7] Cambridge (Ontario) 8-14 November, 2004, 100-109
summary	Tensegrity structures are composed of tension compression components, where the compression components (bars) are discontinuously enclosed within continuous tensile components (cables). From an engineering point of view, a tensegrity structure is characterized by geometric non-linearity and large displacements under loading. Therefore, its prestressed shape and deformation under loading are the result of the combined effect of the geometric parameters that determine the initial configuration of the structure, the level of prestress applied to cables, and the material properties of the component members of the structure. A method for generating the initial geometric configuration of tensegrity structures composed of tensegrity units and a parametric expression of this geometry have already been developed. A novel technology that makes possible the construction of tensegrity structures from the on-site assembly of deployable tensegrity units, which are furnished with a simple mechanism that permits bar-elongation, and, as a result, an increase of the prestress applied to the cables of each unit, is also under development. Also under development is a static analysis method that takes into account the above method for prestressing cables. This paper discusses the features of a system that supports the combined geometric and structural design of tensegrity structures, and integrates a graphical interface to display: a) models of initial geometry, b) geometry of the structure after prestress and loading are applied, and c) magnitude of forces applied to the structure’s component members (bars and cables). The system also provides numerical data to be used in component fabrication, and is therefore expected to become a very valuable tool for the design and construction of tensegrity structures.

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	Computer Visualizations in Planning
source	eDesign in Architecture: ASCAAD's First International Conference on Computer Aided Architectural Design, 7-9 December 2004, KFUPM, Saudi Arabia
summary	A wide range of visualizations have been developed and implemented as tools for urban simulations and visual impact assessment. These include: plans, diagrams, elevations, perspective sketches, renderings, modified photographs (photo renderings and photomontages), slide projections, scale models, movies, videotapes and computer graphics. In the last decade, graphical computer applications have proven to be an increasingly supportive tool in visualization and manipulation of graphical material. This study presents the state of the art of computer visualization in planning. More specifically, the use of web-based computerized visualizations for landscape visual simulation, with the aim to develop a system of visualization techniques as an aid to communicating planning and design scenarios for historically important landscapes and urban places, with particular attention to the city of Nablus in Palestine. This has led to the evaluation of possibilities and potentials of computer use in this field, and to the definition of the visual problems and challenges of the city of Nablus. This study will argue what extra one can draw from computerized visualizations, what is likely to be its impact on future planning and design research, and what this visualization experience really means for historical important locations as in Nablus. The study demonstrates that computerized visualizations can be a powerful tool in representing a cityscape in three-dimensions from different angels. Visualizations will allow better understanding of the components of the city, its landscapes, city features and the process of change. In this way it may provide new and better platforms for public participation in planning.

summary	This study focuses on road environment around robbed convenience stores and elucidates the road characteristics that are conducive to convenience store robberies by using GIS and indexes of graphs and networks. The method of this study is as follows: Five convenience store robberies, which occurred in Metropolitan Tokyo, were selected from newspaper reports. Then, road networks within a 1-kilometer radius of the robbed convenience stores were extracted from digital maps with a scale of one-twenty five hundredth (Geographical Survey Institute and Bureau of City Planning Tokyo Metropolitan Government). After adding the road networks and the attributes such as road width, we investigate the road characteristics using GIS and indexes of graphs and networks. Finally, we demonstrate several factors associated with convenience store robberies based on this compiled information.

summary	Mesh segmentation has become an important and well-researched topic in computational geometry in recent years (Agathos et al. 2008). As a result, a number of new approaches have been developed that have led to innovations in a diverse set of problems in computer graphics (CG) (Sharmir 2008). Specifically, a range of effective methods for the division of a mesh have recently been proposed, including by K-means (Shlafman et al. 2002), graph cuts (Golovinskiy and Funkhouser 2008; Katz and Tal 2003), hierarchical clustering (Garland et al. 2001; Gelfand and Guibas 2004; Golovinskiy and Funkhouser 2008), primitive fitting (Athene et al. 2004), random walks (Lai et al.), core extraction (Katz et al.) tubular multi-scale analysis (Mortara et al. 2004), spectral clustering (Liu and Zhang 2004), and critical point analysis (Lin et al. 20070, all of which depend upon a weighted graph representation, typically the dual of a given mesh (Sharmir 2008). While these approaches have been proven effective within the narrowly defined domains of application for which they have been developed (Chen 2009), they have not been brought to bear on wider classes of problems in fields outside of CG, specifically on problems relevant to generative architectural design. Given the widespread use of meshes and the utility of segmentation in GAD, by surveying the relevant and recently matured approaches to mesh segmentation in CG that share a common representation of the mesh dual, this paper identifies and takes steps to address a heretofore unrealized transfer of technology that would resolve a missed opportunity for both subject areas. Meshes are often employed by architectural designers for purposes that are distinct from and present a unique set of requirements in relation to similar applications that have enjoyed more focused study in computer science. This paper presents a survey of similar applications, including thin-sheet fabrication (Mitani and Suzuki 2004), rendering optimization (Garland et al. 2001), 3D mesh compression (Taubin et al. 1998), morphin (Shapira et al. 2008) and mesh simplification (Kalvin and Taylor 1996), and distinguish the requirements of these applications from those presented by GAD, including non-refinement in advance of the constraining of mesh geometry to planar-quad faces, and the ability to address a diversity of mesh features that may or may not be preserved. Following this survey of existing approaches and unmet needs, the authors assert that if a generalized framework for working with graph representations of meshes is developed, allowing for the interactive adjustment of edge weights, then the recent developments in mesh segmentation may be better brought to bear on GAD problems. This paper presents work toward the development of just such a framework, implemented as a plug-in for the visual programming environment Grasshopper.

summary	The proposal of "Urbamedia" is to undertake the development of 3D virtual and interactive models of historical areas of Latin-American cities. The selected zone is the "Mayo Avenue" including the "Mayo Square", an historical place of the city of Buenos Aires, Argentina; this project is financed by the National Agency of Scientific and Technological Development of Argentina and the University of Buenos Aires.We are presenting the first experimental model of the "Mayo Square" that has been developed at ABACUS, Department of Architecture & Building Aids Computer Unit, University of Strathclyde UK. combined with a system analysis of urban activities using the “Atlas.ti” CAQDAS software.This particular use of the “Atlas.ti” software is under experimental applications to this type of urban analysis procedures; allowed us the possibility to analysed a set of activities by means of graph theory as result of a series of interviews to the people working in the area. We are also looking to include historical areas of three cities: Mar del Plata, Rosario and Santa Fe (Argentina) and eventually other cities from Latin América as Rio de Janeiro and Habana.Due that ABACUS has a strong experience in city modelling plus the powerful software and hardware used there, we must develop a VRML customized menu to be adapted to our low cost PC equipment. The 3D model will be used mainly in urban design simulation procedures and the idea is to extend to other type of simulations of the environmental parameters.

title	GEOMETRY AND ARCHITECTURE: NURBS, DESIGN AND CONSTRUCTION
source	Proceedings of the Fourth International Conference of Mathematics & Design, Special Edition of the Journal of Mathematics & Design, Volume 4, No.1, pp. 135-139.
summary	Geometry regarded as a tool for understanding is perhaps the part of Mathematics which is the most intuitive, concrete and linked to reality. From its roots as a tool to describe and measure shapes, geometry as ‘the space science’ , has grown towards a theory of ideas and methods by means of which it is possible to build and study idealised models, not only from the physical world but also from the real world. In graphic architecture thought, geometry usually appears as an instrumental support for project speculation. Geometric procedures are presented as representational resources for the graphic testing of reflection and for the exposition of ideas in order to build a logical order as regards representation and formal prefiguration. The fast rise of computing in the last decades has made it possible for architects to work massively and in a graphic and intuitive way with mathematical representations of tridimensional geometry, such as the NURBS . These organic surfaces of free shapes defined by vectorial curves have allowed access to a rapid generation of complex shapes with a minumum amount of data and of specific knowledge. The great development of modelling achieved by the digital media and the limitations in the technical and building areas and in the existence of materials which are coherent with the resultant shapes reveal a considerable distance between the systems of ideation and simulation characteristic of the computing era and the analogous systems of production inherited from the slow industrial development. This distance has been shortened by CAD/CAM systems, which are, however, not very accessible to the architectural field. If we incorporate to the development of these divergent media the limitations which are distinctive of the material resources and procedures of the existent local technology, the aforementioned distance seems even greater. Assuming the metaphor of living at the threshold of two ages (industrial-computing, analogical-digital, material-virtual) and the challenge of the new conceptual and operational tools in our field, we work in the mixture, with no exclusions or substitutions, proposing (by means of the development of informational complements) some alternatives of work to approach the issue under discussion from the Architecture Workshop.

title	Artificial intelligence and emergence in architecture: A multi-agent based model for design processes
source	SIGraDi 2004 - [Proceedings of the 8th Iberoamerican Congress of Digital Graphics] Porte Alegre - Brasil 10-12 november 2004
summary	The purpose of this paper is to provide an alternative approach to traditional design process formulation and elaboration. In contrast to traditional models of design process fundamentally defined by the abstract manipulation of objects, this study recognizes that the resources available for rethinking architecture are to be found in a reformulation of its theory and practice. This reformulation should be based on non-linear design processes in which dynamic emergence and invention take the place of a linear design process fixed on a particular object evolution. Design is possible to be defined in two different and commonly confused ways; one as the process of designing or design activity and the second as the product of designing. In this study, we are concerned with design as a process to emphasize the misconceptions, derived from studying design products solely. Therefore, we propose a change from a design knowledge based on objects to a one focused on design as a network of processes.

summary	Our research objective is searching for a model of an projection process that appropriately involves digital systems and analog proceedings of Industrial Design projection by taking advantage of each medium. Aim is to amplify projection abilities of students by increasing their expressive and cognitive possibilities. For this reason, we have finished an experimentation within a class of digital graphics. We have found that analog means are a motivation in learning with digital tools, assuming that the technique is guided by the concept already defined by means of software experimentation. In addition, we have concluded that students learned more dynamic, because it was focused to practice and not to pure theory, which can be easily forgotten by students.

title	Understanding Pre-Construction Simulation Activities to Adapt Visualization in 4D CAD Collaborative Tools
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 477-492.
summary	Increasing productivity and efficiency is an important issue in the AEC field. This area is mainly characterized by fragmentation, heterogeneous teams with low lifetimes and many uncertainties. 4D CAD is one of the greatest innovations in recent years. It consists in linking a 3D model of the building with the works planning in order to simulate the construction evolution over time. 4D CAD can fill several needs from design to project management through constructivity analysis and tasks planning (Tommelein 2003). The literature shows that several applications have been proposed to improve the 4D CAD use (Chau et al. 2004; Lu et al. 2007; Seok & al. 2009). In addition, studies have shown the real impact of 4D CAD use in construction projects (Staub-French & Khanzode 2007; Dawood & Sika 2007). More recently, Mahalingam et al. (2010) showed that the collaborative use of 4D CAD is particularly useful during the pre-construction phase for comparing the constructability of working methods, for visually identifying conflicts and clashes (overlaps), and as visual tool for practitioners to discuss and to plan project progress. So the advantage of the 4D CAD collaborative use is demonstrated. Moreover, several studies have been conducted both in the scientific community and in the industrial world to improve it (Zhou et al. 2009; Kang et al. 2007). But an important need that remains in collaborative 4D CAD use in construction projects is about the adaptation of visualization to the users business needs. Indeed, construction projects have very specific characteristics (fragmentation, variable team, different roles from one project to another). Moreover, in the AEC field several visualization techniques can represent the same concept and actors choose one or another of these techniques according to their specific needs related to the task they have to perform. For example, the tasks planning may be represented by a Gantt chart or by a PERT network and the building elements can be depicted with a 3D model or a 2D plan. The classical view (3D + Gantt) proposed to all practitioners in the available 4D tools seems therefore not suiting the needs of all. So, our research is based on the hypothesis that adapting the visualization to individual business needs could significantly improve the collaboration. This work relies on previous ones and aim to develop a method 1) to choose the best suited views for performed tasks and 2) to compose adapted multiple views for each actor, that we call ‚Äúbusiness views‚Äù. We propose a 4 steps-method to compose business views. The first step identifies the users‚Äô business needs, defining the individual practices performed by each actor, identifying his business tasks and his information needs. The second step identifies the visualization needs related to the identified business needs. For this purpose, the user‚Äôs interactions and visualization tasks are described. This enables choosing the most appropriate visualization techniques for each need (step 3). At this step, it is important to describe the visualization techniques and to be able to compare them. Therefore, we proposed a business view metamodel. The final step (step 4) selects the adapted views, defines the coordination mechanisms and the interaction principles in order to compose coordinated visualizations. A final step consists in a validation work to ensure that the composed views really match to the described business needs. This paper presents the latest version of the method and especially presents our latest works about its first and second steps. These include making more generic the business tasks description in order to be applicable within most of construction projects and enabling to make correspondence with visualization tasks.

title	A model proposal for digitisation and recording data on architectural heritage in Poland based on European guidelines and best practices.
source	University of Strathclyde, Dept. of Architecture and Building Science, Glasgow UK
summary	The aim of the research is an adoption of digital technology in the recording and management of architectural heritage of Poland. The current documentation practice does not fit to the present needs. The existing system of built heritage recording and protection in Poland was developed during the 1960s and the 1970s. It is based on a database of paper fiches. Although the documenting template allows the collection of comprehensive information on historic buildings, the whole system of heritage protection remains petrified. The database verification and upgrade is usually delayed, and moreover, the records do not include some information crucial for successful protection and regeneration of historical buildings. The lack of computer aided documentation system causes, furthermore, inadequate management of the heritage. Central to the research methodology is the belief that a computer aided documentation system for built heritage in Poland should be compatible and harmonised with similar European projects as a response to the needs of the emerging Information Society. To achieve that standards and best practices in Europe were identified, analysed and compared with the current Polish system of heritage protection and management. Activities of Scottish organisations from the cultural heritage sector, being in the forefront of European achievements, were studied in detail. It was observed that Scottish advancements might be a source of valuable lessons and guidelines for similar activities in Poland. The issues crucial to designing a framework model for digitisation and recording data on architectural heritage in Poland were given particular attention. These included aspects related to content, technology, legislation, and project organisation. As a result a number of recommendations were formulated and supported with necessary tables and diagrams. This specification is intended as a starting point for implementation of digital technology in recording and management of architectural heritage of Poland. It is believed that the research outcomes may become useful not only for the architectural heritage documentation and management, but also in the wider cultural heritage sector in Poland. The thesis concludes with a statement that the validity of any guidelines related to the digital technology has a limited lifespan, and therefore the proposed model for digitisation and recording data on architectural heritage in Poland, to be successful, requires constant, diligent review of the technology development.

source	SIGraDi 2004 - [Proceedings of the 8th Iberoamerican Congress of Digital Graphics] Porte Alegre - Brasil 10-12 november 2004
summary	The virtual reconstruction of the archeological site of Madinat al-Zahra. in Córdoba (Spain) has permitted a new approach to the study and comprehension of this palatine city as well as to the typologies of Islamic architecture in Al-Andalus during the 10th century. Starting from fieldwork and from a photogrammetric survey of the site, the digital model has become a highly qualified tool in the research process. Through virtual navigation, it allows to learn new aspects about spatial configuration of this characteristic constructions that configure the basis for the development of further architectures during the following centuries. Furthermore, being conscious that knowledge is basic for cultural heritage preservation, this 3D reconstruction model is an important instrument for general dissemination and for implementing a visit to this significant case of Islamic architecture in Spain.

title	Virtual Architecture as Representation for Creative Design Process - Through a Collaborative eDesign Studio
doi	https://doi.org/10.52842/conf.ecaade.2005.037
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 37-45
summary	Using Virtual Architecture (VA) as a general scheme for representations to sustain the reflection activities involved in the design process can help students to initiate creative design ideas. Because of its implicit abstract nature, VA can be used, to represent original ideas or processes, or well-known architectural theories to articulate design ideas. Furthermore, VA as a mean of expression, turn out to be a source of inspiration for students who perceive it as medium with very few limits with which to develop, explore and express their design intuitions. A recent collaborative edesign studio experience is reported to illustrate the benefit observed. Using three examples out of ten student projects, we show how designs and design process have been characterized by those virtual representations. In fall semester 2004, the edesign studio took place between the Schools of Architecture of Toulouse and Université Laval in Québec. VA was both an academic and a studio topic at Laval while the other school students had a traditional design task to tackle, namely the rehabilitation of Chapou University Residences for students in Toulouse. Students from both schools composed each edesign team. In addition, three common architectural themes were web-documented and introduced to both classes: room, as defined by Louis Kahn: “a space which knows what it wants to be is a room”; color, as an architectural medium in dialectic with structure; and body-space relationships, as articulated by Gilles Deleuze and its projection to cyberspace. From the edesign studio results, we are arguing that virtual architecture should be looked at not only as new domain to be investigated by architects and taught in academic studios but also as a new medium of design to develop and explore design intuitions through virtual representations.

title	COMPUTER DESIGN OF REPEATING HYPERBOLIC PATTERNS
source	Proceedings of the Fourth International Conference of Mathematics & Design, Special Edition of the Journal of Mathematics & Design, Volume 4, No.1, pp. 83-90.
summary	From antiquity, humans have created 2-dimensional art on flat surfaces (the Euclidean plane) and on surfaces of spheres. However, it wasn't until about 50 years ago that designers have created art in the third "classical geometry", the hyperbolic plane. Inspired by a diagram from the mathematician H. S. M. Coxeter, the graphic artist M. C. Escher became the first person to design such patterns, performing all the needed constructions laboriously by hand. In order to exhibit the true hyperbolic nature of such art, the pattern must exhibit symmetry and repetition. It seems natural to use a computer to avoid the tedious hand constructions performed by Escher. This was our goal: to design and implement a computer program to create repeating hyperbolic patterns.

title	MORPHOGENESIS – EVOLUTION OF SHAPE; IMAGINATION AMPLIFIER VERSION 1.0
source	ETH postgraduate studies final thesis, Zurich
summary	The advent of computer technologies in the design-processes has already taken place, is meanwhile ordinary. New design perspectives are opened, and an almost inexhaustable form repertoire is available, even buildable - ‘Nothing is impossible‘. This thesis work deals only with a small clip from there. Essentially it consists of two parts: » MORPHOGENESIS – Evolution of Shape « describes the present situation of generating shape with the help of computers. Some of the technologies that are used for, as comupter-morphing or evolutionary programming, are examined more closely here. »IMAGINATION AMPLIFIER Version 1.0« is an interactive Form-Generator for houses - a House-Machine. The program deals with the possibilities of interpolation and morphing between two, 3 dimensional, states (Startand Target-House) configured by the user. As an output–result, the generator depicts the put in number of steps in between, with characteristic values like cubical contents (V), surface quadrature (A) and the relation between V/A. All the results are stored in a database, where it is possible to select from for new morphing operations, to get in the end closer to a more optimized shape.

title	O uso do ciberespaço na visualização da forma arquitetônica de espaços internos em fase de projeto [The Use of Cyberspace in Architectural Form Visualization in Interior Spaces during the Design Process]
source	SIGraDi 2004 - [Proceedings of the 8th Iberoamerican Congress of Digital Graphics] Porte Alegre - Brasil 10-12 november 2004
summary	The architecture graphics presentation, showing three-dimensional space designed by the architect from bidimensional elements, besides being insufficient. But, just the three-dimensional presentation of this space does no guarantee its total visualization. It is necessary a way in which the observer can visualize and interact with it. For that reason it is needed to use the digital space. But, it can not be limited to the presentation of three-dimensional objects, because it brings the possibility of communication and information transmission through cyberspace. So, an investigation was done through bibliographical references and questions to architects to study how and what the graphics elements should be demonstrate for the correct visualization. Next, with those information, it was developed a prototype site to the visualization of the internal spaces of a design used as an example and after that this prototype was verified in a group of architects and a group of non-expert people.
