title	VRML History: Storing And Browsing Temporal 3DWorlds
source	Proceedings of the fourth symposium on the virtual reality modeling language, ACM Press, pp. 153-160
summary	Spatio-temporal data are presented and explored by VR-based visualization systems which offer 3D-navigation and time-navigation for better immersion and analysis. If the visualization results are disseminated on the WWW, they are mostly transformed into videos or, recently, into animated VRML-files which neither support 3D-navigation nor time navigation nor a time-referenced data representation. In this paper, the script language VRML History is proposed which supports the description of spatio-temporal worlds on the internet by conceptually extending VRML with a new time dimension. This is realized by a set of new nodes representing temporal geometries and time references, and a set of Java-classes extending standard VRML-browsers to perform time navigation.

title	Design-Based on VR-Modeling of Environemntal Conditions
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 126-129
summary	The research on CAD has been looking for a long time a creative contribution to architectural design, including recently the use of virtual-reality as an immersive modeling system, but without much practical results. However, contemporary architecture is increasingly including digital characteristics based more on cultural influences than on the use of electronic tools. This shows an evolution of the discipline in relation to digital media and apparently distant from environmental concerns. But the works and reflexions reveal a common convergence in the role of body in architecture as a pivot between virtual and local dimension of design. Based on that relationship we propose to take advantage of virtual-reality for modeling environmental conditions of the location in order to guide architectural design, using for example the potential of representing characteristics not visible in reality or to simulate time cycles. Sun displacement, wind direction, temperature ranges, topography and landscape are specific conditions in design that define energy consumption and human comfort. Such characteristics can establish optimal shapes crossing the different variables with timelines. VR-modeling and interactive control allow an spatial evaluation of environmentally efficient forms. That is showed through an exercise of housing in different locations of Chile. This merger between digital media and ecological concerns represents a crossing of contemporary cultural trends to motivate exploration of new geometries, supported on the potential of technology and on sustainable human development

title	Computer Architectural Representation - Applying the VOIDs Framework to a Bridge Design Scheme
source	Architectural Computing from Turing to 2000 [eCAADe Conference Proceedings / ISBN 0-9523687-5-7] Liverpool (UK) 15-17 September 1999, pp. 387-394

summary	A virtual environment presents sensory information and visual feedback to the user in order to give convincing illusion of an artificial world. In the architectural profession, the spatio-temporal metaphor in itself constitutes significant information retrieval, because we understand architecture by seeing it. This paper attempts to understand, and then to analyse the characteristics of representation of architectural models in virtual environments. We will examine the use and creativity of current computer generated architectural presentation in virtual environments. Our observations will be applied to the modelling of a bridge in Castlefield, Manchester, and evaluated by a group of students within the School of Architecture at Sheffield University. The conclusion of this paper will be the presentation of a conceptual structure for representing architectural models in virtual environments. This paper also explores the tension between the correspondence and constructivist views of representation. The correspondence view of representation relies on the idea that a representation corresponds to what is out there in the world. The constructivist view of representation advocates that any actual interpretation would depend on the context of their social and cultural backgrounds. However, the authors believe there should be a combination of these two views for architectural representation in virtual environments, and a framework developed by the authors - VOIDs will be presented.

title	Envisioning Cyberspace: Designing 3D Electronic Spaces
source	McGraw-Hill, NY
summary	Free of the constraints of physical form and limited only by imagination, new environments spring to life daily in a fantastic realm called cyberspace. The creators of this new virtual world may be programmers, designers, architects, even children. In this invigorating exploration of the juncture between cyberspace and the physical world, architect Peter Anders brings together leading-edge cyberspace art and architecture ... inspiring new techniques and technologies ... unexpected unions of reality and virtuality ... and visions of challenges and opportunities as yet unexplored. More than an invitation to tour fantastic realms and examine powerful tools, this book is a hard-eyed look at cyberspace's impact on physical, cultural, and social reality, and the human-centered principles of its design. This is a book that will set designers and architects thinkingNand a work of importance to anyone fascinated with the fast-closing space between the real and the virtual.

title	Evaluation of Spatial Perception in Virtual Environments
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 145-148
summary	The 3D environments created by computers can be used as a powerful simulation tool for architecture, especially with inmersive devices, but it is necessary to know properly their spatial characteristics to use it effectively. It is also important to consider their possibilities in communication networks and their implications in contemporary architecture. For this reason, the goal of this research is to evaluate the perception of virtual architectonic spaces in relation to the perception of real architectonic spaces. This research is based on the comparison of experiences of university students in a real space (Entrance Hall of Faculty of Economy) and in the same space modeled by a computer. The evaluation considers tests with stereoscopic helmets and interactive navigation, making questionnaires to characterize the sensation of dimensions, relationships and time for an specific activity. The measuring of real and virtual spaces are made through references (furniture, textures, etc.) or by proportional relations between height, width and depth, in different patterns. The experience also reveals mental schemes to perceive the dimension of architectonic space and the orientation in a real and virtual environment. Besides, the research allows to relate the different levels of complexity and information with the understanding of real architectonic space and modeled space.

title	THE EXPERIENCE OF SPACE IN FULL-SCALE MODELS AND VIRTUAL REALITY
source	Full-scale Modeling and the Simulation of Light [Proceedings of the 7th European Full-scale Modeling Association Conference / ISBN 3-85437-167-5] Florence (Italy) 18-20 February 1999, pp. 67-74
summary	Do we experience the size and character of virtual spaces in the same way as real spaces? What impact has the meaning of a space, i.e. furniture and other clues to the use of a space, on our experience of it? This paper describes an experiment where the participants could navigate through a room, first on desktop-VR, then in full-scale VR (in a CAVE) and finally in a full-scale model. In a first phase the room was empty and only defined through walls, windows and doors. Later on furniture was added as well as colors and textures. The experiment was a pilot study and threw light on some questions which we intend to develop in further investigations. It showed that the participants used building components like doors and windows and furniture in the presentation on desktop VR for their estimation of the size of the room. In the CAVE and in the full-scale model the participants' bodies were the measure for their estimations. The experiment also hinted at that color and texture had an impact on the experience of size.

title	Arties: Meta-Design as Evolving Colonies of Artistic Agents
source	International Conference on Generative Art
summary	Meta-design, the act of designing a system or species of design instead of a design instance, is an important concept in modern design practice and in the generative design paradigm. For meta-design to be a useful tool, the designer must have more formal support for both design species definition/expression and the abstract attributes which the designer is attempting to embody within a design. Arties is an exploration of one possible avenue for supporting meta-design. Arties is an artistic system emphasizing the co-evolution of colonies of Artificial Life design or artistic agents (called arties) and the environment they inhabit. Generative design systems have concentrated on biological genetics metaphors where a population of design instances are evolved directly from a set of ‘parent’ designs in a succession of generations. In Arties, the a-life agent which is evolved, produces the design instance as a byproduct of interacting with its environment. Arties utilize an attraction potential curve as their primary dynamic. They sense the relative attraction of entities in their environment, using multiple sensory channels. Arties then associate an attractiveness score to each entity. This attractiveness score is combined with a 'taste' function built into the artie that is sensitized to that observation channel, entity, and distance by a transfer function. Arties use this attraction to guide decisions and behaviors. A community of arties, with independent evolving attraction criteria can pass collective judgement on each point in an art space. As the Artie moves within this space it modifies the environment in reaction to what it senses. Arties support for Meta-design is in (A) the process of evolving arties, breeding their attraction potential curve parameters using a genetic algorithm and (B) their use of sensory channels to support abstract attributes geometries. Adjustment of these parameters tunes the attraction of the artie along various sensing channels. The multi-agent co-evolution of Arties is one approach to creating a system for supporting meta-design. Arties is part of an on-going exploration of how to support meta-design in computer augmented design systems. Our future work with Arties-like systems will be concerned with applications in areas such as modeling adaptive directives in Architecture, Object Structure Design, spatio-temporal behaviors design (for games and simulations), virtual ambient spaces, and representation and computation of abstract design attributes.

doi	https://doi.org/10.52842/conf.ecaade.1999.418
summary	The Bartlett School of Graduate Studies, University College London (UCL), set up the first MSc in Virtual Environments in the UK in 1995. The course aims to synthesise and build on research work undertaken in the arts, architecture, computing and biological sciences in exploring the realms of the creation of digital and virtual immersive spaces. The MSc is concerned primarily with equipping students from design backgrounds with the skills, techniques and theories necessary in the production of virtual environments. The course examines both virtual worlds as prototypes for real urban or built form and, over the last few years, has also developed an increasing interest in the the practice of architecture in purely virtual contexts. The MSc course is embedded in the UK government sponsored Virtual Reality Centre for the Built Environment which is hosted by the Bartlett School of Architecture. This centre involves the UCL departments of architecture, computer science and geography and includes industrial partners from a number of areas concerned with the built environment including architectural practice, surveying and estate management as well as some software companies and the telecoms industry. The first cohort of students graduated in 1997 and predominantly found work in companies working in the new market area of digital media. This paper aims to outline the nature of the course as it stands, examines the new and ever increasing market for designers within digital media and proposes possible future directions for the course.

summary	This project investigates in the limits of the word like only means of structuring of the thought, before the appearance of new paradigms: the multimedias and the ciber-space that have transformed so much the language written as the architectural one causing unpublished situations: 1.) The transformation of a concrete container to other virtual. 2.) The transformation of the design object, of one static material to another that is a process. 3.) The transformation in the traditional ways of thinking (reversible as the formal logic of the mathematics) to new imaginarys epistemologicals. // These non alone events have caused changes in the forms of to know and to communicate the reality but rather the same one suffers a dilation process. We present for their exploration, a road synthesized in some hypotheses that were elaborated with reason of the International Competition of ACADIA 1998: 1.) The new communication systems (cibercomunication) they generate a new territory that should be colonized. This territory this conformed by objects related by infinite bonds (hipertext). 2.) The topographical form is not lineal and sequential, this it is multidirectional and multiradial. The phenomenon of the blow-up and the dilation are the mechanisms with those that the new objects are generated. 3.) These related fields generate interstitial empty spaces where it appears the desire. The interstice like existential space.

title	Toolspaces and Glances: Storing, Accessing, and Retrieving Objects in 3D Desktop Applications
source	Proceedings of the Symposium on Interactive 3D Graphics 1999. pp. 163-168
summary	Users of 3D desktop applications perform tasks that require accessing data storage, moving objects, and navigation. These operations are typically performed using 2D GUI elements or 3D widgets. We wish to focus on interaction with 3D widgets directly in the 3D world, rather than forcing our users to repeatedly switch contexts between 2D and 3D. However, the use of 3D widgets requires a mechanism for storing, accessing, and retrieving these widgets. In this paper we present toolspaces and glances to provide this capability for 3D widgets and other objects in interactive 3D worlds. Toolspaces are storage spaces attached to the user's virtual body; objects placed in these spaces are always accessible yet out of the user's view until needed. Users access these toolspaces to store and retrieve objects through a type of lightweight and ephemeral navigation we call glances.

title	Hyperarchitecture: Spaces in the Electronic Age
source	Birkhauser
summary	In an age dominated by the Internet and electronic media it is becoming increasingly clear that our perception of space is also undergoing a profound transformation. The author takes the reader on a fascinating journey, revealing who has played a part in this transformation. Avant-garde artists, including Boccioni, Duchamp and Kandinsky, the architect Gropius, philosophers such as Wittgenstein and psychoanalysts like Carl Gustav Jung all contributed to this development. Today, our awareness of traditional architectural space is changing; buildings are being rendered transparent, fleeting and intangible, enhanced by virtual potential. The author looks at works by Rem Koolhaas, Jean Nouvel, Frank Gehry, Zaha Hadid, James Wines, Daniel Libeskind, Toyo Ito, which reflect building in an age of virtual realism.

source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 197-200
summary	There is an assumption that architecture can provide an evocative vision of an artificial environment using digitalized and wireless communication technology. It is a ideal based on perception of virtual space, where distance is minimized through the continual process of breaking barriers in none visible planes. It is domain of mind, in which the object becomes real by individual choice. It is conceived in a plane known as virtual space or cyber space. Marcos Novak describes it as "space created as habitat for our imagination". I approach the topic trying to establish a connection between the boundaries of virtual space and real space through architecture. These are the objectives of my inquiry: 1) To explore an architectural form in a media of non-concrete space. Space created by a negative space (empty space, residual space, loading space). 2) To define a new technology that marks the beginning of a real virtual environment accessible to everybody. Proposing the idea of socialization through the architecture and revitalizing negative spaces comprehended as valuable public places. 3) Identification and representation of sources that make possible telecommunication technology in an enclosed space. Prototype of a new communicational platform re-interpreted by cyber space, digital images, high-speed data, mobile Internet and application based on Intranets, extranets and mobile multimedia.

title	The comparison of animation, virtual reality, and scenario scripting in design process

summary	Design media is a fundamental tool, which can incubate concrete ideas from ambiguous concepts. Evolved from freehand sketches, physical models to computerized drafting, modeling (Dave, 2000), animations (Woo, et al., 1999), and virtual reality (Chiu, 1999; Klercker, 1999; Emdanat, 1999), different media are used to communicate to designers or users with different conceptual levels¡@during the design process. Extensively employed in design process, physical models help designers in managing forms and spaces more precisely and more freely (Millon, 1994; Liu, 1996).Computerized drafting, models, animations, and VR have gradually replaced conventional media, freehand sketches and physical models. Diversely used in the design process, computerized media allow designers to handle more divergent levels of space than conventional media do. The rapid emergence of computers in design process has ushered in efforts to the visual impact of this media, particularly (Rahman, 1992). He also emphasized the use of computerized media: modeling and animations. Moreover, based on Rahman's study, Bai and Liu (1998) applied a new design media¡Xvirtual reality, to the design process. In doing so, they proposed an evaluation process to examine the visual impact of this new media in the design process. That same investigation pointed towards the facilitative role of the computerized media in enhancing topical comprehension, concept realization, and development of ideas.Computer technology fosters the growth of emerging media. A new computerized media, scenario scripting (Sasada, 2000; Jozen, 2000), markedly enhances computer animations and, in doing so, positively impacts design processes. For the three latest media, i.e., computerized animation, virtual reality, and scenario scripting, the following question arises: What role does visual impact play in different design phases of these media. Moreover, what is the origin of such an impact? Furthermore, what are the similarities and variances of computing techniques, principles of interaction, and practical applications among these computerized media?This study investigates the similarities and variances among computing techniques, interacting principles, and their applications in the above three media. Different computerized media in the design process are also adopted to explore related phenomenon by using these three media in two projects. First, a renewal planning project of the old district of Hsinchu City is inspected, in which animations and scenario scripting are used. Second, the renewal project is compared with a progressive design project for the Hsinchu Digital Museum, as designed by Peter Eisenman. Finally, similarity and variance among these computerized media are discussed.This study also examines the visual impact of these three computerized media in the design process. In computerized animation, although other designers can realize the spatial concept in design, users cannot fully comprehend the concept. On the other hand, other media such as virtual reality and scenario scripting enable users to more directly comprehend what the designer's presentation.Future studies should more closely examine how these three media impact the design process. This study not only provides further insight into the fundamental characteristics of the three computerized media discussed herein, but also enables designers to adopt different media in the design stages. Both designers and users can more fully understand design-related concepts.

summary	"Space," which has long been an important concept in architecture (Bloomer & Moore, 1977; Mitchell, 1995, 1999), has attracted interest of researchers from various academic disciplines in recent years (Agnew, 1993; Benko & Strohmayer, 1996; Chang, 1999; Foucault, 1982; Gould, 1998). Researchers from disciplines such as anthropology, geography, sociology, philosophy, and linguistics regard it as the basis of the discussion of various theories in social sciences and humanities (Chen, 1999). On the other hand, since the invention of Internet, Internet users have been experiencing a new and magic "world." According to the definitions in traditional architecture theories, "space" is generated whenever people define a finite void by some physical elements (Zevi, 1985). However, although Internet is a virtual, immense, invisible and intangible world, navigating in it, we can still sense the very presence of ourselves and others in a wonderland. This sense could be testified by our naming of Internet as Cyberspace -- an exotic kind of space. Therefore, as people nowadays rely more and more on the Internet in their daily life, and as more and more architectural scholars and designers begin to invest their efforts in the design of virtual places online (e.g., Maher, 1999; Li & Maher, 2000), we cannot help but ask whether there are indeed sensible spaces in Internet. And if yes, these spaces exist in terms of what forms and created by what ways?To join the current interdisciplinary discussion on the issue of space, and to obtain new definition as well as insightful understanding of "space", this study explores the spatial phenomena in Internet. We hope that our findings would ultimately be also useful for contemporary architectural designers and scholars in their designs in the real world.As a preliminary exploration, the main objective of this study is to discover the elements involved in the creation/construction of Internet spaces and to examine the relationship between human participants and Internet spaces. In addition, this study also attempts to investigate whether participants from different academic disciplines define or experience Internet spaces in different ways, and to find what spatial elements of Internet they emphasize the most.In order to achieve a more comprehensive understanding of the spatial phenomena in Internet and to overcome the subjectivity of the members of the research team, the research design of this study was divided into two stages. At the first stage, we conducted literature review to study existing theories of space (which are based on observations and investigations of the physical world). At the second stage of this study, we recruited 8 Internet regular users to approach this topic from different point of views, and to see whether people with different academic training would define and experience Internet spaces differently.The results of this study reveal that the relationship between human participants and Internet spaces is different from that between human participants and physical spaces. In the physical world, physical elements of space must be established first; it then begins to be regarded as a place after interaction between/among human participants or interaction between human participants and the physical environment. In contrast, in Internet, a sense of place is first created through human interactions (or activities), Internet participants then begin to sense the existence of a space. Therefore, it seems that, among the many spatial elements of Internet we found, "interaction/reciprocity" Ñ either between/among human participants or between human participants and the computer interface Ð seems to be the most crucial element.In addition, another interesting result of this study is that verbal (linguistic) elements could provoke a sense of space in a degree higher than 2D visual representation and no less than 3D visual simulations. Nevertheless, verbal and 3D visual elements seem to work in different ways in terms of cognitive behaviors: Verbal elements provoke visual imagery and other sensory perceptions by "imagining" and then excite personal experiences of space; visual elements, on the other hand, provoke and excite visual experiences of space directly by "mapping".Finally, it was found that participants with different academic training did experience and define space differently. For example, when experiencing and analyzing Internet spaces, architecture designers, the creators of the physical world, emphasize the design of circulation and orientation, while participants with linguistics training focus more on subtle language usage. Visual designers tend to analyze the graphical elements of virtual spaces based on traditional painting theories; industrial designers, on the other hand, tend to treat these spaces as industrial products, emphasizing concept of user-center and the control of the computer interface.The findings of this study seem to add new information to our understanding of virtual space. It would be interesting for future studies to investigate how this information influences architectural designers in their real-world practices in this digital age. In addition, to obtain a fuller picture of Internet space, further research is needed to study the same issue by examining more Internet participants who have no formal linguistics and graphical training.

summary	Physical models are used in order to elucidate the lack of clarity found in the two-dimensional representations of design, and digital models have provided a more effective way of differentiating curvature and space with greater accuracy. What are the fundamental differences of these two approaches that plays the most significant role in modern design? This research attempts to analyze in depth the differences by operating an experiment that would determine the factors play a relevant role and describe some of the relevant phenomenon and establish criteria to aid this analysis.

Originally designed to enable the interchange of 3-D CAD models between different systems, like SGML, it has defined and uses a general mechanism for representing and managing complex data of any type. Increasingly products are defined as solid models that are stored in product databases. These databases are not limited to shape but contain a considerable wealth of other information, such as materials, failure modes, task descriptions, product related meta-data such as approvals and much more. The product world is of course also replete with documents, from requirements through specifications to user manuals. These documents both act as input to the product development processes and are output as well. Indeed in some cases documents form part of the product and are given part numbers. It is therefore not surprising to find that there are many companies where there are very real requirements to interact and interoperate between the product data and documents, specifically in the form of SGML-based data. This paper reports on work in progress to bring the two worlds together. This is primarily being done through the SGML and Industrial Data Preliminary Work Item under ISO TC184/SC4. The need for common capabilities for using STEP and SGML together has been obvious for a long time as can be seen from the inclusion of product data and SGML-based data within initiatives such as CALS. However, until recently, this requirement was never satisfied, for various reasons. For the last year or more, a small group has been actively pursuing this area and gaining the necessary understandings across the different standards. It is this work that is reported here. The basic thrust of the work is to answer the questions: Can STEP and SGML be used together and, if so, how?
