title	Digital Design - Research and Practice
source	Proceedings of the 10th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-1210-1 / Tainan (Taiwan) 13–15 October 2003, 464 p.
summary	The use of computers in the design of the built environment has reached a watershed. From peripheral devices in the design process, they have in recent years come to take centre stage. An illustration is immediately at hand. Just as the entries to the competition for the Chicago Tribune Tower in 1922 defined the state-of-the-art at the beginning of the twentieth century, we have a similar marker at the end of the century, the competition in 2002 to replace the World Trade Centre towers in Lower Manhattan offered us a range of architectural solutions that exemplified the state-of-the-art eighty years later, setting forth not only architectural statements but also illustrating clearly the importance of computers in the design of the built environment. In these entries of 2002, we can see that computers have not only become essential to the communication of design but in the investigation and generation of structure, form and composition. The papers in this book are the current state-of-the-art in computer-aided design as it stands in 2003. It is the tenth in a series sponsored by the CAAD Futures Foundation, compiled from papers presented at the biennial CAAD Futures Conferences. As a series, the publications have charted the steady progress in developing the theoretical and practical foundations for applications in design practice. This volume continues in that tradition; thus, this book is entitled Digital Design: Research and Practice. The papers are grouped into three major categories, reflecting thrusts of research and practice, namely: Data and information: its organisation, handling and access, including agents; Virtual worlds: their creation, application and interfaces; and Analysis and creation of form and fabric. The editors received 121 abstracts after the initial call for contributions. From these, 61 abstracts were selected for development into complete papers for further review. From these submissions, 39 papers were chosen for inclusion in this publication. These papers show that the field has evolved from theoretical and development concerns to questions of practice in the decade during which this conference has showcased leading work. Questions of theoretical nature remain as the boundaries of our field expand. As design projects have grasped the potentials of computer-aided design, so have they challenged the capabilities of the tools. Papers here address questions in geometric representation and manipulation (Chiu and Chiu; Kocaturk, Veltkamp and Tuncer), topics that may have been considered to be solved. As design practice becomes increasingly knowledge based, better ways of managing, manipulating and accessing the complex wealth of design information becomes more pressing, demanding continuing research in issues such as modelling (Yang; Wang; Zreik et al), data retrieval and querying (Hwang and Choi; Stouffs and Cumming; Zreik, Stouffs, Tuncer, Ozsariyildiz and Beheshti), new modes of perceiving data (Segers; Tan). Tools are needed to manage, mine and create information for creative work, such as agents (Liew and Gero; Smith; Caneparo and Robiglio; Ding et al) or to support design processes (Smith; Chase). Systems for the support and development of designs continue (Gero; Achten and Jessurun). As progress is made on some fronts, such as user interfaces, attention is again turned to previously research areas such as lighting (Jung, Gross and Do; Ng et al; Wittkopf; Chevier; Glaser, Do and Tai) or services (Garcia; Chen and Lin). In recent years the growth of connectivity has led to a rapid growth in collaborative experience and understanding of the opportunities and issues continues to mature (Jabi; Dave; Zamenopoulos and Alexiou). Increasing interest is given to implications in practice and education (Dave; Oxman; Caneparo, Grassi and Giretti). Topics new to this conference are in the area of design to production or manufacture (Fischer, Burry and Frazer; Shih). Three additional invited papers (Rekimoto; Liu; Kalay) provide clear indication that there is still room to develop new spatial concepts and computer augmented environments for design. In conclusion, we note that these papers represent a good record of the current state of the evolving research in the field of digital 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,

title	A generative design system based on evolutionary and mathematical functions
source	International Conference on Generative Art
summary	Previous work by Professor John Frazer on Evolutionary Architecture provides a basis for the development of a system evolving architectural envelopes in a generic and abstract manner. Recent research by the authors has focused on the implementation of a virtual environment for the automatic generation and exploration of complex forms and architectural envelopes based on solid modelling techniques and the integration of evolutionary algorithms, enhanced computational and mathematical models. Abstract data types are introduced for genotypes in a genetic algorithm order to develop complex models using generative and evolutionary computing techniques. Multi-objective optimisation techniques are employed for defining the fitness function in the evaluation process.

title	Resource-Adaptive 3D Maps for Location Based Services
source	UMDS '02 Proceedings, Prague (Czech Republic) 2-4 October 2002, I.29-I.38
summary	In this paper, we present a database driven approach for managing and visualizing 3D urban city models and related multimedia content. Such a 3D database is a core component of a 3D Cadastre system (Coors 2002a). In the TellMaris project (IST 2000- 28249, www.tellmaris.com), we will make use of the 3D database to generate 3D maps. The objective of TellMaris is the development of a generic 3D-map interface to tourist information on mobile computers. The interface provides a new concept for creating value added information services on mobile computers for the European citizens related to geographical information. The interface is in the project used for accessing tourist information relevant for boat tourism in the Baltic Sea and Aegean Sea area in the Mediterranean. In this paper we focus on the online generation and compression of 3D-maps in order to make use of these maps in a mobile enviroment.

title	Architectural Window - Computer networks as planning and integration tools
doi	https://doi.org/10.52842/conf.ecaade.2002.302
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. 302-305
summary	As building projects become increasingly more complex, the number of project participants increases as does their spatial distribution. An effective decentralised work process and co-operation is of increasing importance. The global computer network, the internet, has great potential and recent times have seen the development of a variety of techniques in this field. The project proposal described here is based upon this approach and also takes it a step further. A specific analysis of the subject and the subsequent identification of potential approaches formed the basis for an architectural application that brings the architect in contact with other project participants using the internet as a powerful yet simple and easy to use medium. The project is currently (2002) undergoing practice tests and academic investigation and is installed on a freely-accessible server.

title	Diseño de Interfase - Metodología de acercamiento a la construcción de entornos virtuales [Interphase Design - Methodology of Approach to the building of Virtual Environments]
source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 175-179
summary	The project we are presenting is based on our professional experience in virtual interface design of multimedia, in CD-ROM and Web format, which has been developed in our design workshops. Our project methodology has one common basis: The metaphorical and conceptual argument for the creation of virtual environments is supported by the observation of the physical environment of human beings and the objects that surround them.The research we have carried out is aimed at establishing a project methodology for interface design based on the hypothesis that observation and knowledge of the relationship between man and environment (architectural and urban), man and object (literacy and symbolic representation) is the basis for the design of recognizable virtual environments. These are functional, representative and efficient elements for the achievement of communicative objectives of such virtual environments. The project reference that supports our research is the outcome of academic and professional project analysis. These projectswill support the demonstration of the suggested methodology which, in the course of the presentation, will be applied to a project to be developed and whose metaphorical basis is the city of Valparaiso.The objective is to use the urban environment as a metaphorical argument for the design of a virtual environment for the Cultural and Historical Registry of Literature, Plastic Arts and Chilean Architecture where Valparaiso has served as reference, source of inspiration and object of study. Together with the methodological project, we will present the instruments that have been created for reference analyis with the purpose of interface design and in order to facilitate a mechanism to evaluate interface design projects.

title	Virtual Reality/Space Visualization in Design Education: The VR-Desktop Initiative
doi	https://doi.org/10.52842/conf.ecaade.2002.064
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. 64-71
summary	Although virtual reality (VR) is a fast-growing field, utilization of its potential within an affordable environment in the early years of architectural education has been limited. Currently, we are in the process of exploring the educational potential of virtual reality in the creation and understanding of space as a set of dynamic volumes that can be experienced. The VR-Desktop initiative is an effort to bring the salient features of projection-based VR to second-year architecture students in a way that is more generally accessible than the many canonical, first-generation, projection-based VR systems. The VR-Desktop has been implemented in the teaching of the architectural design studio in the second year of a fiveyear curriculum, as part of the physical architectural studio. Through the VR-Desktop system in the studio, students immediately start working in an immersive environment. They create space by manipulating solids and voids while evaluating the anthropometric relations of the proposed solution. The students are able to study and test conceptual details in a virtual environment from the very beginning of their architectural design project. In order to assess student perception of the usefulness of various system attributes for diverse tasks, we have begun a usability study. Thirty-five surveys were collected from the students who had used the lab during the two semesters for which the two-screen system was available. Preliminary observations indicate that within the architectural context, virtual reality techniques involving depth perception can convey relevant information to students more efficiently and with less misrepresentation than traditional techniques. This paper suggests that full field of view, motion, stereoscopic vision, and interactivity are possible components of the 3D visualization techniques that are necessary to enhance architectural education

title	Experiments in Architectural Form Generation Using Cellular Automata
doi	https://doi.org/10.52842/conf.ecaade.2002.552
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. 552-555
summary	These experiments are based on previous work in developing cellular automata in three dimensions and to suggest architectural forms. Current research is extended by including explicit architectural considerations, such as, individual space units, supporting structure, floor plates, and the development of an envelope. A basic spatial shape is demonstrated in both linear and curved configurations. Also included is a discussion to not only explicitly use mathematically based concepts for form generation but more importantly their interpretation into architectural forms, as well as, the concept of considering architectural elements from the very start of the generative process.

title	Shapes, Numbers, Perception: Aspects and Dimensions of the Design-Performance Space
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 design-performance space denotes a virtual space that can be constructed based on discretized design variables and performance indicators. For an n-dimensional design-performance space, n = d + p,whereby d = the number of discrete design variables, and p = the number of discrete performance indicators. Once constructed, this space can be visualized and used by the designer to explore the relationship between design variables and corresponding performance attributes. We present, for the building design domain, an approach to generation and exploration of the design-performance space. In this approach, an initial design is used to generate a set of alternative designs that collectively constitutethe design space. One way of doing this relies on the "scalarization" of design variables. The scalarization leads to the representation of a building as a point in a d-dimensional design space. Each coordinate ofsuch a space accommodates a salient (semantic or geometric) design variable. Subsequently, the entire corpus of design alternatives is subjected to performance modeling. Based on the modeling results, an ndimensionaldesign-performance space is constructed. We specifically address the potential for and limitations of describing building geometry in terms of a continuous scalar dimension of the design space. We introduce the concept of "Relative Compactness", which is derived by comparing the volume tosurface area ratio of a shape to that of a (compact) reference shape with the same volume. We present the results of an empirical study, which shows a significant correlation between the numeric values of relativecompactness and the subjective evaluation of the compactness of architectural shapes.

title	Hybridized Measurement: Interpreting historical images of Sagrada Família Church in Barcelona using CAD-based digital photogrammetry
doi	https://doi.org/10.52842/conf.ecaade.2002.448
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. 448-455
summary	This paper gives an account of the extrapolated use of digital photogrammetry undertaken by the Spatial Information Architecture Laboratory (SIAL) in the pursuit for new interpretations of historical images at the Sagrada Família Church. The work is an extension of the research activities undertaken as part of the Australian Research Council (ARC) Strategic Partnerships with Industry – Research and Training (SPIRT) project New onto Old : 3D flexible computer modelling to aid heritage building restoration, recycling and extension, where digital photogrammetry was first explored as a measurement tool for non-specialist implementation. The research makes use of the link between Computer Aided Design (CAD) and digital photogrammetry in a reverse manner, using built spatial data to produce orthographic rectified images of what was intended from the historical drawings and models of the architect Antoni Gaudí (1852-1926).

summary	In the paper-based world, CAAD-associations, such as eCAADe, and scientific publishers aim at getting the right people together and for making sure their work gets distributed to their peers. Electronic networks, such as the Internet, are providing scientists with the means to pursue those activities on their own. In this paper we present the goals of an EU project called SciX. The goal of SciX is to analyze the business processes of scientific publishing, to invent new publication models and through a series of pilots to demonstrate how this should work. In the envisioned scenarios, professional associations such as eCAADe play an important role. Their members are the potential users of SciX’s platforms, authors and readers of the papers. Associations could also become the publishers and archivists of the knowledge created within their respective community. The objectives of this contribution focus on involving the eCAADecommunity in the developments in SciX, on fine-shaping the goals as well as on defining the requirements and monitoring the usability of the pilots.

source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 94-96
summary	This paper describes and illustrates three very different uses of Information and Computing Technology (ICT) to represent, interpret and provide access to the city of Glasgow, Scotland’s largest city. The first application is a web-based three dimensional model of the city centre comprising the topography of the landform, the road and river networks and around 10,000 individual buildings. The model provides the interface to a number of different databases and search engines help the user explor the city. The second application is a recently completed CD-ROM illustrating, from an aerial perspective, the growth of the city from pre-historic times to the present. It comprises 230 images, 140,000 words of text, 5 video clips and 35 sound clips. The third application is to create a web-based massive archive of images (around 10,000) and historical events, personalities, objects and themes that can be updated and enlarged inexpensively and made available on-line to the widest possible audience.

title	Using Social Interaction in Generative Design of Shared Virtual Spaces
source	International Conference on Generative Art
summary	The proposed paper outlines research findings in the field of generative design of visual virtual chat spaces. It discusses social interaction as a central determining factor in the generation of virtual spaces through and for chat communication on the World Wide Web. Social interaction in a chat room is based on communication using written text. The research and design results of this project involve the translation of chat statements into three-dimensional virtual objects according to - criteria derived from theories of virtual and social space, - the production of space through action and interaction of the users of the interface and - the translation of the components of written text (words and characters) into three-dimensional virtual forms. The generation of a dynamic, virtual, social structure is based on criteria deduced from systems of interaction within social space. The visual social structure, reflected in the shape and spatial relation of the three-dimensional objects, evolves as source for feedback processes and therefore as “re-generation” of social interaction. This paper documents the design, implementation and evaluation of the described system. It represents an outset and a first manifestation of a new project in cultural-differentiated user-interaction-centred generative approaches in interface design of chat room applications.

title	Space-related Content-Management
doi	https://doi.org/10.52842/conf.ecaade.2002.400
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. 400-403
summary	Establishing virtual city models (“digital cities“) has become an important planning tool for configuring the future of our cities and vital spaces. The present contribution discusses the concept of “Space-related Content-Management” and its interlaceable possibilities of implementation in the planning and configuration process. The activities of those acting in space and their impacts on space, e.g. leading to new, additional and renovation of buildings, to the demolition of buildings, to alterations regarding vegetation stock, traffic infrastructure, etc., do not result from a static conception of physical space, but exclusively suggest a dynamic one. Real space is subject to continuous changes. The constant changing of physical space thus represents a considerable factor concerning the conception of the virtual image (virtual city model). The dynamics of space suggests the development of “data-pipelines“ as core elements of virtual city models. Only this pipeline-concept can account for the dynamics of space. It is suggested to embed “datapipelines“ in “Content-Management-Systems (CMS)“ thus promoting the concept of “Space-related Content-Management“ including all kinds of space-related information enriched with metainformation that might be useful during the planning- and configuration process. “Space-related Content-Management-Systems (SCMS)“ are considered as navigation systems through complex space-related data sets supporting a broad range of questions during the planning- and configuration process. The application fields of “Space-related Content Management-Systems“ are supposed to integrate the complete planning process starting with the space-related analysis and model generation via characterization of space and winds up at the development of space-related concepts to be passed on to those involved in the space under consideration.

title	Reinterpretation or replacement? The effects of the information and communication technologies on urban space
source	CORP 2002, Vienna, pp. 345-349
summary	The timid question “Virtual spaces or real places?” forms the core of many debates within the spatial sciences addressing theconsequences of the rapid development of information and communication technologies1 on existing spatial structures. So far several opinions rival each other for the interpretation of current and the prediction of future spatial developments. The spacelessness ofcomputer networks and the possibility to transmit data in real-time have lead visionaries to predict a far-reaching devaluation of timeand space, so questioning the future importance of traditional spatial structures: The “annihilation of distance and time constraints [incomputer networks] could undermine the very rationale for the existence of the city by dissolving the need for physical proximity”(Graham and Marvin 1996: 318). The disappearance of the city into the net, therefore, seems to become a distinct possibility.

title	Possibilities and Constraints of using Virtual Reality in Urban Design
source	CORP 2002, Vienna, pp. 457-463
summary	This study aims at exploring the rapid growth of the use of Virtual Reality techniques in the field of Urban Design. Currently, VirtualReality —the ultimate representation— and Virtual Environments are the most growing fields of information technology and have agreat media attention. This research discusses the possibilities and limitations of applying Virtual Reality (VR) technology inenvironmental simulations for urban design practice. There is evidence to suggest that the use of such technology will enhanceconceivable image of any proposed project at any urban setting for users, designers and clients. Therefore, city officials andadministrators (clients) and the public (users) can reach better decisions regarding proposed projects within their towns and cities.Specifically, this research structured in several interdependent parts: the first part is concerned with the definition of VR as well as abackground of its history and current achievements. Types and components of VR systems are described and traditional simulationtechniques are reviewd. In addition, a discussion of current attempts in incorporating VR in urban design disciplines are presented.This discussion raises the question of appropriateness of the VR techniques in urban design projects. An assesment of both potentialsand limitations of aplying this technique, i.e. VRML (Virtual Reality Modelling Language), are discussed. This study definespotentialities, constraints and problems of using this technique, and recommends future research efforts in the field of using theVirtual Reality as a medium for delivering real content for those interested in the design of the built environment.

summary	For various purposes, virtual city applications have been developed around the globe to provide users with online resources and services over the Internet. Following our research on the Sheffield Urban Contextual Databank (SUCoD) project, this paper presents an alternative framework for building virtual cities, which goes beyond conventional static urban modelling. A three-tier system framework is described in conjunction with the design and implementation of the SUCoD prototype. We demonstrate SUCoD's novel functionalities by showing that complex urban contextual information sets, including three-dimensional interactive models, multilayer interactive maps, and hypermedia documents, can be retrieved dynamically by user-specified urban contextual attributes, spatial loca- tions, and boundaries. The three-tier framework also facilitates system development in an extensible way, allowing continuous parallel extensions of system functionalities, user-interface components, and contextual data resources. SUCoD's dynamic capabilities are considered crucial in its future uses for urban contextual modelling on demand in relation to the past, present, and future of the City of Sheffield.
