title Evolution of Media for Early Design Stages
source Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary In this paper the evolution of media used at early design stages will be considered. In traditional methods of searching and presenting the design idea, the basic tool used was the graphic representation. Implementation of new digital techniques in 60s - 70s focused on the mathematical way ofrepresentation. These methods were “not architect friendly” (lack of graphic representation traditionally used by architects). As a result, the development of methods for digital support of form searching was terminated. The computer was used as a tool for drafting. Creative usage of computers for form searching through sketching on the display was extremely difficult. The computer could be described as an “incompatible pencil”. Only in recent years can we see new efforts in this area ofdesign methodology. Thanks to new technical possibilities we have a new chance for changing the process of designing. New kinds of software and hardware let us use the computer not as a pen, but as a medium. In this paper different new ways of form searching will be considered (from very simple method as the scansketches to very complicated ones, such as the generic algorithms). At the end, the influence of new media on the process of design will be presented.

title A Java3D Tool for Real-Time Collaboration in a Virtual Reality CAADEnvironment
source Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary Today the development of network-based virtual communities and the use of avatars have brought a new level of complexity to the meaning of virtuality, providing the technology for remote presence and collaborative experiences. In this project the intention was to pursue this articulated vision of VR in order to assist the design profession during the early stages of the design process. The objective was to provide a tool that is capable of creating 3D shapes in a shared VR environment, thus allowing thedesign and its evolution to be shared. The use of the Java programming language was a natural choice for this project. Because of Java’s performance scalability and hardware independence the concept ofCAAD has been extended, making it possible to create a VR environment that can co-exist between high-end supercomputers and standard PCs. The project is currently being tested using PCs and an SGI system running a Reality Centre. The research reported in this paper describes the architecture and application of software that aims to increase the opportunity for collaboration within virtual worlds and enable effective and transparent information exchange.

title Beyond Representation: Real Time Form Finding of Tensegrity Structures with 3d ‘Compressed’ Components
doi https://doi.org/10.52842/conf.ecaade.2009.021
source Computation: The New Realm of Architectural Design [27th eCAADe Conference Proceedings / ISBN 978-0-9541183-8-9] Istanbul (Turkey) 16-19 September 2009, pp. 21-30
summary Tensegrity structures are of interest to architecture and engineering as a practical means to explore lightweight and rapidly deployable modular structures that have a high degree of geometric freedom and formal potency. The notion of tensegrity structures with 3D ‘compressed’ components is introduced and their feasibility is demonstrated through selected physical models. Attempts to further explore the architectural potential of tensegrity structures within a computational environment have proven difficult, as they are statically indeterminate and require form finding procedures to “find a geometry compatible with a self-stress state” (Motro 2002). An overview of tensegrity ‘capable’ software that can be used for architectural design is followed by a discussion that introduces an additional computational method based on particle-spring systems. This approach enables real time manipulation of tensegrity networks. Two projects that utilize this unique tool are described.

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.

title Models of Design Requirement
source Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary Case studies show that significant proportions of design errors and failures are linked to poor requirement specification during both early stages of design and as changes occur. Computational requirements engineering as a front-end to design iterations is a promising area addressing theseproblems. In other design disciplines, such as in software engineering, requirement engineering has given significant product improvements. In this paper, we present a state-space representation of requirement models for architectural design. The purpose of requirement modeling in design is tocreate a process by which requirements can be converted into working design solutions through frontend validation. We suggest three models of requirement specification, co-evolutionary [CoM], multiple domain [MDM] and single domain [SDM] models, that can facilitate this effort. Taken together all three models provide a full set of logical permutations of requirement-solution “worlds” and “operations.” We compare each model against the others in terms of facilitating change management and computability.

title From 2D Base Map To 3D City Model
source UMDS '02 Proceedings, Prague (Czech Republic) 2-4 October 2002, I.17-I.28
summary Since 1997 Helsinki City Survey Division has proceeded in experimenting and in developing the methods for converting and supplementing current digital 2D base maps in the scale 1:500 to a 3D city model. Actually since 1986 project areas have been produced in 3D for city planning and construction projects, but working with the whole map database started in 1997 because of customer demands and competitive 3D projects. 3D map database needs new data modelling and structures, map update processes need new working orders and the draftsmen need to learn a new profession; the 3D modeller. Laser-scanning and digital photogrammetry have been used in collecting 3D information on the map objects. During the years 1999-2000 laser-scanning experiments covering 45 km2 have been carried out utilizing the Swedish TopEye system. Simultaneous digital photography produces material for orto photo mosaics. These have been applied in mapping out dated map features and in vectorizing 3D buildings manually, semi automatically and automatically. In modelling we use TerraScan, TerraPhoto and TerraModeler sw, which are developed in Finland. The 3D city model project is at the same time partially a software development project. An accuracy and feasibility study was also completed and will be shortly presented. The three scales of 3D models are also presented in this paper. Some new 3D products and some usage of 3D city models in practice will be demonstrated in the actual presentation.

title Modeling architectural design objectives in physically based space planning
source Automation in Construction 11 (2) (2002) pp. 213-225
summary Physically based space planning is a means for automating the conceptual design process by applying the physics of motion to space plan elements. This methodology provides for a responsive design process, which allows a designer to easily make decisions whose consequences immediately propagate throughout the design. It combines the speed of automated design methods with the flexibility of manual design methods, while adding a highly interactive quality and a sense of collaboration with the design itself. In our approach, the designer creates a space plan by specifying and modifying graphic design objectives rather than by directly manipulating primitive geometry. The plan adapts to the changing state of objectives by applying the physics of motion to its elements. For design objectives to affect a physically based space plan, they need to apply appropriate forces to space plan elements. Space planning can be separated into two problems, determining topological properties and determining geometric properties. Design objectives can then be categorized as topological or geometric objectives. Topological objectives influence the location of individual spaces, affecting how one space relates to another. Geometric objectives influence the size and shape of space boundaries, affecting the dimensions of individual walls. This paper focuses on how to model a variety of design objectives for use in a physically based space planning system. We describe how topological objectives, such as adjacency and orientation can be modeled to apply forces to space locations, and how geometric objectives, such as area, proportion, and alignment, can be modeled to apply forces to boundary edges.

title Faculties of Architecture
source Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary In order to be inscribed in the European Architect’s register the study program leading to the diploma ‘Architect’ has to meet the criteria of the EC Architect’s Directive (1985). The criteria are enumerated in 11 principles of Article 3 of the Directive. The Advisory Committee, established by the European Council got the task to examine such diplomas in the case some doubts are raised by other Member States. To carry out this task a matrix was designed, as an independent interpreting framework that mediates between the principles of Article 3 and the actual study program of a faculty. Such a tool was needed because of inconsistencies in the list of principles, differences between linguistic versions ofthe Directive, and quantification problems with time, devoted to the principles in the study programs. The core of the matrix, its headings, is a categorisation of the principles on a higher level of abstractionin the form of a taxonomy of domains and corresponding concepts. Filling in the matrix means that each study element of the study programs is analysed according to their content in terms of domains; thesummation of study time devoted to the various domains results in a so-called ‘profile of a faculty’. Judgement of that profile takes place by committee of peers. The domains of the taxonomy are intrinsically the same as the concepts and categories, needed for the description of an architectural design object: the faculties of architecture. This correspondence relates the taxonomy to the field of design theory and philosophy. The taxonomy is an application of Domain theory. This theory,developed by the authors since 1977, takes as a view that the architectural object only can be described fully as an integration of all types of domains. The theory supports the idea of a participatory andinterdisciplinary approach to design, which proved to be awarding both from a scientific and a social point of view. All types of domains have in common that they are measured in three dimensions: form, function and process, connecting the material aspects of the object with its social and proceduralaspects. In the taxonomy the function dimension is emphasised. It will be argued in the paper that the taxonomy is a categorisation following the pragmatistic philosophy of Charles Sanders Peirce. It will bedemonstrated as well that the taxonomy is easy to handle by giving examples of its application in various countries in the last 5 years. The taxonomy proved to be an adequate tool for judgement ofstudy programs and their subsequent improvement, as constituted by the faculties of a Faculty of Architecture. The matrix is described as the result of theoretical reflection and practical application of a matrix, already in use since 1995. The major improvement of the matrix is its direct connection with Peirce’s universal categories and the self-explanatory character of its structure. The connection with Peirce’s categories gave the matrix a more universal character, which enables application in other fieldswhere the term ‘architecture’ is used as a metaphor for artefacts.

title DIAL-Europe: New Functionality’s for an Integrated Daylighting Design Tool
source Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary The European project DIAL-Europe started in April 2000 and intends to enhance and to enlarge the capabilities of the LesoDIAL software. The aim of this “Swiss” tool was to give architects relevant information regarding the use of daylight, at the very first stage of the design process. DIAL-Europe focuses on European standards and climatic data. Further, a Heating & Cooling evaluation module and an Artificial Lighting module will be added. The objective of the Heating & Cooling module is to indicate the implications of the user’s design on heating and cooling energy and on thermal comfort.The objective of Artificial Lighting module is to develop a tool that will give an estimation of illuminance values on the work plane and provide guidance on qualitative aspects and visual comfort as well as on switching control and integration with daylight based on generic light sources and luminaires. Furthermore, the scope of the examples of simulated rooms will be increased in order to allow the user to compare their design with more similar cases. This paper will present the state of achievement and give an overview of the first version of the DIAL-Europe software, which will beavailable at the beginning of 2002.

title Conformance Checking by Capturing and Simulating Human Behaviour in the Built Environment
source Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary In order to model natural human behaviour, it is necessary to capture this behaviour. First, we will start out by modelling behaviour for specific situations, such as taking a seat in a theatre. To capture humanbehaviour, the following experiment is performed: Given a virtual environment, a sufficient number of subjects (real humans) are asked to execute a human task in this virtual environment (e.g. take a seat inthe theatre). Whenever the subject deviates from the shortest path, the system will ask for a clue why this is done. The hypothesis is that the combination of the motion paths and the clues for making/changing decisions will provide decision rules to make reliable predictions about human behaviour under the same conditions when using virtual persons. To test the hypothesis, we propose to use the university’s main conference and presentation hall as a test case. A 3D model and a motion pathgraph are constructed that enables a virtual person to find its way to a selected chair. The clues from the experiment are implemented as decision rules that determine a virtual person’s behaviour. Running thesimulation will result in the following data: Time per person to find a chair, Deviation from the shortest path, Distance covered per person to find a chair, Distribution of seated persons over time and Relocation of persons. To validate the test case, the process of people entering the hall and finding a chair is recorded on videotape. The walking behaviour of the people observed on the video is analysed and compared with the data from the simulation.

title The Virtual Campus: A new place for (lifelong) learning?
doi https://doi.org/10.52842/conf.ecaade.2002.472
source Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 472-477
summary 472 eCAADe 20 [design e-ducation] Modeling Real and Virtual Worlds Session 13 In the early spring of 2001 a collection of German universities founded a virtual faculty of architecture, which was named „Liquid Campus“. Current thinking about future forms of education in the field of architecture combined with over 4 years of experience with net-based design studios, led to questions about the future of existing universities, their buildings and their use. This problem was put to 43 students in the form of a design exercise to create a place for a virtual university. In the current situation, in which the administration of knowledge is more and more located on the internet, and even the so-called meeting places themselves can be virtualised through the help of video-conference-software, the exercise was to design a virtual campus in the framework and to carry out this design work in a simulation of distributed practice. Initial criticism of the project came from the students in that exemplary working methods were not described, but left for the students to discover on their own. The creation of a concept for the Liquid Campus meant that the participants had to imagine working in a world without the face to face contacts that form the basis (at present) of personal interaction. Additionally, the assignment to create or design possible links between the real and the virtual was not an easy task for students who normally design and plan real physical buildings. Even the tutors had difficulties in producing focused constructive criticism about a virtual campus; in effect the virtualisation of the university leads to a distinctive blurring of its boundaries. The project was conducted using the pedagogical framework of the netzentwurf.de; a relatively well established Internet based communication platform. This means that the studio was organised in the „traditional“ structure consisting of an initial 3 day workshop, a face to face midterm review, and a collective final review, held 3,5 months later in the Museum of Communication in Frankfurt am Main, Germany. In teams of 3 (with each student from a different university and a tutor located at a fourth) the students worked over the Internet to produce collaborative design solutions. The groups ended up with designs that spanned a range of solutions between real and virtual architecture. Examples of the student’s work (which is all available online) as well as their working methods are described. It must be said that the energy invested in the studio by the organisers of the virtual campus (as well as the students who took part) was considerably higher than in normal design studios and the paper seeks to look critically at the effort in relation to the outcomes achieved. The range and depth of the student’s work was surprising to many in the project, especially considering the initial hurdles (both social and technological) that had to overcome. The self-referential nature of the theme, the method and the working environment encouraged the students to take a more philosophical approach to the design problem. The paper explores the implications of the student’s conclusions on the nature of the university in general and draws conclusions specific to architectural education and the role of architecture in this process.

title Computation-Universal Voxel Automata as Material for Generative Design Education
source International Conference on Generative Art
summary This paper is a report on the educational application of a voxel automata system for massively parallel execution of computation-universal cellular units in the generative design field. The software, designed and co-developed by the author to enable developmental strategies in generative design - for example with respect to 3D design generation, semantic self-evaluation and self-replication - was applied in teaching at the School of Design at The Hong Kong Polytechnic University to achieve two goals: to teach programming as part of the School’s Interactive Systems Design stream and to teach generative concepts at a theoretical, yet hands-on and highly intensive level. An introduction to the software, its development and its functions as well as a discussion of the teaching/learning experience is given, highlighting design educational aspects and student design work. The paper concludes with an analysis of how student approaches to generative concepts have been affected by the tool and how ideas and feedback from students have supported the ongoing development of the voxel automata system and its documentation.

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 The Quantum Matrix:A Three Dimensional Data Integration and Collaboration ToolFor Virtual Environments
source Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary If a picture is worth a thousand words, what if they could walk and talk? How would you like to bring a whole new dimension to your ideas; to use visualization to convey a sense of time and motion, to use imagery to give your ideas vividness; to use sound to give them voice and view them threedimensionally. The Matrix allows you to do all of this and much more. The Matrix resembles Rubik’s cube, but its purpose is to store, manage and access data of all types and to view them in three dimensions in virtual environments such as the CAVE and on your desktop. The current version can store, access and view almost anything that is in digital form, including:Text files Pictures Video Clips Sound Files Spreadsheets URL’s HTML pages Databases CAD drawings Gantt Charts Business Graphics VRML modelsExecutable Programs OLE (Object Link & Embedded) The Matrix is a three-dimensional multimedia and document management tool. The Matrix anticipates the convergence of electronic media into one consistent environment for analysis and representation. the Matrix uses VMRL and OpenGL technologies to allow the user to be immersed in their data as withCinerama, IMAX and Virtual Reality Environments. The Matrix allows the user to exercise their creativity by interactively placing and organizing their data three dimensionally and navigating through and viewingdata and documents in 3D (monocular and binocular – stereo). The Matrix user interface is simple to use. Employing the now familiar “drag and drop” method to manage data and documents. Items can be placed into the matrix grid at a user selected matrix cube location. Upon dropping a document on a cube it appears as a mapped image onto the surface. Navigating through the 3D Matrix-space is fun. All navigation uses real-time animation giving you instant feed back as to where you are. Data drilling is as simple as mouse click on a Matrix cube. Double clicking the on an object in the matrix activates that object. Data dreams was an image that preexisted the program by several years. The dream was to create a new way oforganizing and exploring data. The Qube image was created using Microstation by Bentley Systems, Inc. The figure was modeled using Poser by MetaCreations and composited using Adobe Photoshop.

title Formulation of an Urban and Regional Planning System Basedon a Geographical Information System and its Application- A Case Study of the Ishikawa Prefecture Area of Japan -
source Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings Avegoor, the Netherlands), 2002
summary An Urban and Regional Planning System based on a geographical information system was developed using four sub-systems consisting of a digital map system, a database system, an analysis and forecast system and a planning system. In this case ARCVIEW GIS software was used as a development tool. The digital map system is formulated by the planar orthogonal coordinate system. The data is converted from digital maps issued by the Geographical Survey Institute of Japan (GSI). The database system has layers of data sets, which consist of statistical data, attribute data of geographical points and characteristics of natural features and the built environment. Several sets of principal census data havebeen converted to mesh data. These kinds of data sets are also utilized to this system. LANDSAT TM data is converted into vector data and linked to the same coordinate system. The analysis and forecast system consists of statistical or mathematical analysis, forecasts and visual presentations of the results. The planning system consists of some planning models and reviewing techniques to evaluate alternatives. As an example, this paper examines the relationship between land use and the temperatureon the ground level in built-up areas.

title OBJECT-ORIENTED DATA MODELING AND WAREHOUSING TO SUPPORT URBAN DESIGN
source Ph.D. Dissertation, School of Architecture, Carnegie Mellon University
summary All over the world, local authorities are moving towards managing and storing urban data in digital form. But the data storage devices used are heterogeneous and typically include relational database management systems (DBMS), GIS and CAD files. As a result, data are present in different locations on different platforms and under different schemas. This poses a problem for software applications meant to support decision-making in urban design that require input from more than one data source. This dissertation demonstrates how data warehousing—combined with object-oriented data modeling—is able to provide a general solution for this problem. Data warehousing is a technique initially developed for business applications, but is equally useful for urban design: The data warehouse constitutes a communication layer between the urban design applications and data sources. It makes the data available through a unified interface that hides the sources themselves and represents that data in terms of a general-purpose, preferably object-oriented, model. The dissertation also describes an implementation prototype of the data model and the data warehouse. The test case of this research is the city of Makkah in Saudi Arabia, which faces significant urban design and planning issues in connection with the pilgrimage (Hajj) that brings millions of visitors to the city every year.

summary All over the world, local authorities are moving towards managing and storing urban data in digital form.

As a result, data are present in different locations on different platforms and under different schemas. This poses a problem for software applications meant to supportdecision-making in urban design that require input from more than one data source. We demonstrate in our paper how data warehousing—combined with object-oriented data modeling—is able to provide a general solution for this problem. Data warehousing is a technique initially developed for businessapplications, but is equally useful for urban design: The data warehouse constitutes a communication layer between the urban design applications and data sources. It makes the data available through a unified interface that hides the sources themselves and represents that data in terms of a general-purpose, preferably object-oriented, model. We also describe an implementation prototype that supports different applications. The City of Makkah in Saudi Arabia provides us with real-world data and a context to test our prototype.

title Urbamedia Desarrollo de una base de datos de fragmentos urbanos de ciudades argentinas y latinoamericanas utilizando tecnología digital “VRML” (Virtual Reality Modelling Language) [“Urbamedia” Database Development of urban fragments of Argentinean and Latin cities utilizing the digital technology of VRML (Virtual Reality Modeling Language)]
source SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 112-115
summary The proposal of “Urbamedia” is to undertake the development of a 3D virtual and interactive model of an historical area of the city of Buenos Aires. The selected zone is the “Mayo Avenue” including the “Mayo Square”; this project is financed by the National Agency of Scientific and Technological Development of Argentina and the University of Buenos Aires.We are presenting and experimental model of the “Mayo Square” that has been developed at ABACUS, Department of Architecture & Building Aids Computer Unit, University of Strathclyde UK. We are also looking to include histórical areas of three cities (Mar del Plata, Rosario and Santa Fe) and eventually other cities from Latin América. 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 simulationsof the environmental parameters.

title Development of a Visual Simulation System Synchronized with Walking Motion - An application for a study of distance perception
source Environmental Simulation - New Impulses in Planning Processes [Proceedings of the 5th European Architectural Endoscopy Association Conference / ISBN 3-922602-85-1]
summary Conventional visual simulators allow observers to move in the simulated space by using a mouse or a joy-stick without the kinesthetic feeling of motion. However, the link between visual image and body motion is important to perceive the environment, especially when people are walking. In this paper, a visual simulation system was designed to synchronize the subject's walking motion on a treadmill with the video image shown on a HMD. In order to detect the walking motion, sensors were attached to both subject’s ankles. According to the detected motion, the treadmill rotates and a CCD camera moves in a model space. Because of the sensors’ low sensitivity and the time lag between the detected motion and treadmill rotation, the subjects couldn’t walk smoothly. Therefore, the walking speed which synchronizes with the video image was kept constant for each subject and the experimenter started up and stopped the simulator. The validity of this simulation system was examined by comparing the accuracy of distance estimation using the new simulator with that using the conventional system without walking motion. The “distance reproduction” method was applied to measure the perceived distance: subjects walked 25 meter in a real setting without being told the distance, and were asked to move the same distance in different conditions. Since the distance estimation became accurate in the condition with the walking motion, the validity of this simulator was secured. The following experiment was intended to investigate the influence of physical environmental features on perceived distance by using the simulation system. We operated some features using a scale model of a route and examined their influences. Subjects were asked to "walk" through a path consisted of two spaces with different physical features, and to respond by showing the proportion of the length of those two spaces. The result revealed that the distance of a narrower and lower ceiling path where people perceive clearer line perspective and faster optical flow tends to be perceived longer.

title Real Teaching and Learning through Virtual Reality
doi https://doi.org/10.52842/conf.ecaade.2002.072
source Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 72-79
summary This paper addresses an articulated vision of Virtual Reality which lends itself to design collaboration in teaching, learning and communication of architectural design ideas among students, design professionals and client body during the early stages of the design process. Virtual Reality (VR) has already acquired a new degree of complexity through development of network-based virtual communities and the use of avatars. The intrinsic quality of VR technology is to support collaborative design experience. The design tools developed for this experiment are capable of creating 3D objects in a shared VR environment, thus allowing the design and its evolution to be shared. The choice of programming language (JavaTM) reflects the desire to achieve scalability and hardware independence, which in turn allows for creation of a VR environment that can co-exist between high-end supercomputers and standard PCs. The prototype design environment was tested using PC workstations and an SGI system running a Reality Centre. The research and teaching/learning experience in the collaborative design environment reported in this paper describe the development and application of software that aims to increase the opportunity for architects to collaborate within virtual worlds which enable effective and transparent information exchange.
