summary This paper evaluates the possibilities for the use of computer aided design and desktop virtual reality technologies as tools for architectural composition. An experimental teaching programme involving undergraduate architectural students at the University of Luton, in which aspects of compositional theory are explored through the direct creation of architectural form and space in digital formats is described. In the programme principles of architectural composition, based upon the ordering and organisation of typological architectural elements according to established rules of composition are introduced to the students through the study of recognised works of design theory. CAD and desktop virtual reality are then used to define and manipulate architectural elements, and to make formal and spatial evaluations of the environments created. The paper describes the theoretical context of the work, assesses the suitability of the software used for performing compositional manipulations, and evaluates the qualities of immersion and intuitive feedback which virtual reality based modelling can offer in the design visualisation process. The teaching programme utilises standard software packages, including AutoCAD, and 3D Studio, as well as Superscape VRT, a PC based desktop VR package.

title Collage, Technology, and Creative Process
source International Conference on Generative Art
summary Since the turn of the twentieth century artists have been using collage to suggest new realities and changing concepts of time. Appropriation and simulation can be found in the earliest recycled scraps in Cubist collages. Picasso and Braque liberated the art world with cubism, which integrated all planes and surfaces of the artists' subjects and combined them into a new, radical form. The computer is a natural extension of their work on collage. The identifying characteristics of the computer are integration, simultaneity and evolution which are inherent in collage. Further, the computer is about "converting information". There is something very facinating about scanning an object into the computer, creating a texture brush and drawing with the object's texture. It is as if the computer not only integrates information but different levels of awareness as well. In the act of converting the object from atoms to bits the object is portrayed at the same conscious level as the spiritual act of drawing. The speed and malleability of transforming an image on the computer can be compared to the speed and malleability of thought processes of the mind. David Salle said, "one of the impulses in new art is the desire to be a mutant, whether it involves artificial intelligence, gender or robotic parts. It is about the desire to get outside the self and the desire to trandscend one's place." I use the computer to transcend, to work in different levels of awareness at the same time - the spiritual and the physical. In the creative process of working with computer, many new images are generated from previous ones. An image can be processed in unlimited ways without degradation of information. There is no concept of original and copy. The computer alters the image and changes it back to its original in seconds. Each image is not a fixed object in time, but the result of dynamic aspects which are acquired from previous works and each new moment. In this way, using the computer to assist the mind in the creative processes of making art mirrors the changing concepts of time, space, and reality that have evolved as the twentieth century has progressed. Nineteenth-century concepts of the monolithic truth have been replaced with dualism and pluralism. In other words, the objective world independent of the observer, that assumes the mind is separate from the body, has been replaced with the mind and body as inseparable, connected to the objective world through our perception and awareness. Marshall Mcluhan said, "All media as extensions of ourselves serve to provide new transforming vision and awareness." The computer can bring such complexities and at the same time be very calming because it can be ultrafocused, promoting a higher level of awareness where life can be experienced more vividly. Nicholas Negroponte pointed out that "we are passing into a post information age, often having an audience of just one." By using the computer to juxtapose disparate elements, I create an impossible coherence, a hodgepodge of imagery not wholly illusory. Interestingly, what separates the elements also joins them. Clement Greenberg states that "the collage medium has played a pivotal role in twentieth century painting and sculpture"(1) Perspective, developed by the renaissance archetect Alberti, echoed the optically perceived world as reality was replaced with Cubism. Cubism brought about the destruction of the illusionist means and effects that had characterized Western painting since the fifteenth century.(2) Clement Greenberg describes the way in which physical and spiritual realities are combined in cubist collages. "By pasting a piece of newspaper lettering to the canvas one called attention to the physical reality of the work of art and made that reality the same as the art."(3) Before I discuss some of the concepts that relate collage to working with computer, I would like to define some of the theories behind them. The French word collage means pasting, or gluing. Today the concept may include all forms of composite art and processes of photomontage and assemblage. In the Foreword on Katherine Hoffman's book on Collage Kim Levin writes: "This technique - which takes bits and pieces out of context to patch them into new contexts keeps changeng, adapting to various styles and concerns. And it's perfectly apt that interpretations of collage have varied according to the intellectual inquiries of the time. From our vantage point near the end of the century we can now begin to see that collage has all along carried postmodern genes."(4) Computer, on the other hand is not another medium. It is a visual tool that may be used in the creative process. Patrick D. Prince's views are," Computer art is not concrete. There is no artifact in digital art. The images exist in the computer's memory and can be viewed on a monitor: they are pure visual information."(5) In this way it relates more to conceptual art such as performance art. Timothy Binkley explains that,"I believe we will find the concept of the computer as a medium to be more misleading than useful. Computer art will be better understood and more readily accepted by a skeptical artworld if we acknowledge how different it is from traditional tools. The computer is an extension of the mind, not of the hand or eye,and ,unlike cinema or photography, it does not simply add a new medium to the artist's repertoire, based on a new technology.(6) Conceptual art marked a watershed between the progress of modern art and the pluralism of postmodernism(7) " Once the art is comes out of the computer, it can take a variety of forms or be used with many different media. The artist does not have to write his/her own program to be creative with the computer. The work may have the thumbprint of a specific program, but the creative possibilities are up to the artist. Computer artist John Pearson feels that,"One cannot overlook the fact that no matter how technically interesting the artwork is it has to withstand analysis. Only the creative imagination of the artist, cultivated from a solid conceptual base and tempered by a sophisticsated visual sensitivity, can develop and resolve the problems of art."(8) The artist has to be even more focused and selective by using the computer in the creative process because of the multitude of options it creates and its generative qualities.

title The ideological basis of generative expression in design
source International Conference on Generative Art
summary This paper will discuss issues concerning the design ideology supporting the use and development of generative design. This design ideology is based on the unique qualities of craft production and on the forms or ideas from nature or the natural characteristics of materials. The main ideology presented here is the ideology of the 1980´s art craft production in Finland. It is connected with the general Finnish design ideology and with the design ideology of other western countries. The ideology for these professions is based on the common background of design principles stated in 19th century England. The early principles developed through the Arts and Crafts tradition which had a great impact on design thinking in Europe and in the United States. The strong continuity of this design ideology from 19th century England to the present computerized age can be detected. The application of these design principles through different eras shows the difference in the interpretations and in the permission of natural decorative forms. The ideology of the 1980ïs art craft in Finland supports the ideas and fulfilment of generative design in many ways. The reasons often given as the basis for making generative design with computers are in very many respects the same as the ideology for art craft. In Finland there is a strong connection between art craft and design ideology. The characteristics of craft have often been seen as the basis for industrial design skills. The main themes in the ideology of the 1980´s art craft in Finland can be compared to the ideas of generative design. The main issues in which the generative approach reflects a distinctive ideological thinking are: Way of Life: The work is the communication of the maker´s inner ideas. The concrete relationship with the environment, personality, uniqueness, communication, visionary qualities, development and growth of the maker are important. The experiments serve as a media for learning. Taste and Aesthetic Education: The real love affair is created by the non living object with the help of memories and thought. At their best objects create the basis in their stability and communication for durable human relationships. People have warm relationships especially with handmade products in which they can detect unique qualities and the feeling that the product has been made solely for them. Counter-culture: The aim of the work is to produce alternatives for technoburocracy and mechanical production and to bring subjective and unique experiences into the customerïs monotonious life. This ideology rejects the usual standardized mass production of our times. Mythical character: There is a metamorphosis in the birth of the product. In many ways the design process is about birth and growth. The creative process is a development story of the maker. The complexity of communication is the expression of the moments that have been lived. If you can sense the process of making in the product it makes it more real and nearer to life. Each piece of wood has its own beauty. Before you can work with it you must find the deep soul of its quality. The distinctive traits of the material, technique and the object are an essential part of the metamorphosis which brings the product into life. The form is not only for formïs sake but for other purposes, too. You cannot find loose forms in nature. Products have their beginnings in the material and are a part of the nature. This art craft ideology that supports the ideas of generative design can be applied either to the hand made crafts production or to the production exploiting new technology. The unique characteristics of craft and the expression of the material based development are a way to broaden the expression and forms of industrial products. However, for a crafts person it is not meaningful to fill the world with objects. In generative, computer based production this is possible. But maybe the production of unique pieces is still slower and makes the industrial production in that sense more ecological. People will be more attached to personal and unique objects, and thus the life cycle of the objects produced will be longer.

title A Model of Land use Conversion and Its Application
source Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary A quantitative model for analyzing the spatial distribution of land use utility is proposed. This model is based on the random bidding theory in which location behavior is decided according to the size of utility to be obtained. The utility function used here consists of the benefit and the cost in the process of land use transition. The benefit is described as the positive utility that can be obtained by doing the corresponding land use at the place. The cost is described as the negative utility that is necessary forchanging the land use from one state to the others. The most likelihood method is generally employed to estimate the parameters of this kind of models. However, we attempt to propose the other statistical method through the mathematical consideration. Using this model, it is possible to obtain the spatial distribution of land use utility that differs with the places and with the land use states. We can also evaluate the effects of a change of land-price or construction costs on our utility. Namely, our locationbehavior can be estimated numerically relating with the social or economic factors. As numerical examples, we apply the proposed model to the actual land use data and access the effectiveness of the model.

title Virtual Reconstruction of Synagogues Systematic Maintenance of Modeling Data
doi https://doi.org/10.52842/conf.ecaade.2002.512
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. 512-517
summary Computer-assisted reconstruction of no-longer existent (architectural) objects and their surroundings practically amounts to a “virtual comeback”. Irreversible destruction having removed identity-establishing buildings from the urban surface for all times is the principal cause for the attempt of renewed imaginating. Following the destruction of the so-called “Reichskristall-Night” of November 1938 the synagogues of the Jewish community in Vienna surely are to be considered for a virtual reconstruction. 60 years later, in the commemorative year of 1998 the first synagogue reconstruction was initiated. The medium-range goal, however, aims at the reconstruction of at least ten further synagogues within a project to be carried out in stages to be pursued over a period of several years. Fluctuations concerning the people involved in handling also call for a structure to be tracked down later on. This contribution deals with handling of modeling in a systematic manner aiming at a traceable data structure being of utmost importance for subsequent use and following-up work.

title Grammars and Pedagogy - Towards new Media Art and Design Education Strategies
doi https://doi.org/10.52842/conf.caadria.1998.385
source CAADRIA ‘98 [Proceedings of The Third Conference on Computer Aided Architectural Design Research in Asia / ISBN 4-907662-009] Osaka (Japan) 22-24 April 1998, pp. 385-394
summary The impact of computational grammatical design on pedagogy has received little attention in art education due to the dominant modes of traditional approaches to art and design education. This paper explores the pedagogical implications of grammatical strategies using computers for judgements of design within an art educational setting. Grammatical strategies are studied for their effect on the judgements of novice artists in a new media educational context. It is argued that concepts of grammar and views of contingency are used in a variety of senses in the conception and form making of artists; that finding methods for discussing and utilising complex visual information is aided by grammatical formalisation; that these strategies are evidently effective at both early and mature stages of the realisation of a project. The research explores the relation between computer and art on three levels in which grammar is used: as a sense of grammar, as a computational paradigm and as a description of a kind of computer program. Grammatical formalism is apparent in two dimensional linear and non-linear animations using Photoshop, Premiere and Director, and in solid modelling programs such as Extreme 3D, Form Z, Strata Studio Pro, 3D Studio Max and SoftImage. Web site construction also impacts on the judgements of 2D and 3D design. Computational grammatical programs generate forms that reflect alternative understandings of art and design. Art practise is defined in terms of developing consistent and appropriate design language for the contingency at hand. Form making using grammatical tools, both recursive and array types, is discussed in terms of their applicability and educative value. Reference is made to formal qualities for critique and strategic capability of alternative pedagogy for generation of forms. Examples provided show how simple rule sets develop into complex derivational sequences that challenge traditional strategies for computer imaging. The paper demonstrates the value of a sense of grammars for novice art and design practitioners by using first hand examples of experimental work at the South Australian School of Art, University of South Australia. For novice artists and designers, grammars in conjunction with reflective practice is offered as a useful mind set that supports an interest in actively defining a new kind of art. Illustrations provided show the utility of a contingent sense of grammar for pedagogy and highlights the significant role of grammar in pedagogy.

title Representation, Realism and Computer Generated Architectural Animation
source Cyber-Real Design [Conference Proceedings / ISBN 83-905377-2-9] Bialystock (Poland), 23-25 April 1998, pp. 241-249
summary This paper documents a simple architectural form which, but for computer generated animation, has no ready alternative explanatory process for its complex generation. The subject is a column in the nave of the Sagrada Familia Church in Barcelona conceived by Gaudí at the beginning of this century without the contemporary opportunities for animated design exploration. The column is based on a set of counter-rotating mutually interfering profiles. As the column gains height, the profiles increase in interference with each other resulting in an increasingly fluted cross section, a tendency towards the Doric Order. For most, however, there is no easy access to a plausible explanation of the inherent rationale for the column. Animating the generation of the column reveals a unique and concealed sublimation of natural patterns of growth. Animation aids an understanding of the effect of the fourth dimension on design itself by releasing a meaning of time from an otherwise inanimate object. Here animation is used to decipher one aspect of the mystery of Gaudí's design while strengthening another: the source and conceptual power of Gaudí to anticipate this phenomenon. Rather than trivialising this design mystery, the explanatory role of the animation enriches comprehension of the formal concept of mutation through displacement or an evolutionary design paradigm. The paper discuss the implications of this ability to show transition, translation and dislocation without delving too deeply into how the animation was made, nor indeed the subject which, after all, requires animation to fully represent its less tangible qualities.

source Digital Design Studios: Do Computers Make a Difference? [ACADIA Conference Proceedings / ISBN 1-880250-07-1] Québec City (Canada) October 22-25, 1998, pp. 290-299
summary A primary lesson of a beginning design studio is the development of a fundamental design competence. This entails acquiring skills of integration, projection, exploration, as well as critical thinking–forming the basis of thinking “like a designer.” Plaguing the beginning architectural design student as she develops this competence are three typical problems: a lagging visual intelligence, a linking of originality with creativity, and the belief that design is an act of an individual author instead of a collaborative activity. We believe that computation support for design learning has particular attributes for helping students overcome these problems. These attributes include its inherent qualities for visualization, for explicitness, and for sharing. This paper describes five interactive multi-media exercises exploiting these attributes which were developed to support a beginning design studio. The paper also reports how they have been integrated into the course curriculum.

title The Artist´s Intentions and Genetic Coding in Algorithmically Generated Drawings
source International Conference on Generative Art
summary Art-work, based on line drawings, is challenging for a number of reasons. It is a very much reduced art form relying on and exploiting the calligraphic qualities of lines only. It is more related to writing than to painting and it has a transient element in it, which is attributed to the movements of the pen equipped hand. With the aid of computer programs line drawings can be produced, exhibiting very specific qualities. In asking what a single line is composed of, we may draw analogies to genetic coding and generate variations within a population of lines belonging to the same family. An artist can cast his intentions into the definition of such a genetic code and the drawings produced accordingly will populate a specific domain of the universe of machine generated drawings.

title The Role of Artifacts in Collaborative Design
doi https://doi.org/10.52842/conf.caadria.1998.271

summary With the proliferation of digital technology, a new category of design artifacts, usually described with the term virtual, has emerged. Virtual artifacts have gained further prominence due to the advances made in collaboration software and networking technologies. These technologies have made it easier to communicate design intentions through the transfer and sharing of virtual rather than physical artifacts. This becomes particularly true in the case of long-distance or international collaborative efforts. This paper compares the two major categories of artifacts – the physical and the computer-based – and places them in relationship to an observed collaborative design process. In order to get at their specific roles in collaboration, two case studies were conducted in which designers in academic and professional settings were observed using a methodology which focused on participation in the everydayness of the designer as well as casual discussions, collection of artifacts, note-taking, and detailed descriptions of insightful events. The collected artifacts were then categorized according to the setting in which they were created and the setting in which they were intended to be used. These two attributes could have one of two values, private or public, which yield a matrix of four possible categories. It was observed that artifacts belonging in the same quadrant shared common qualities such as parsimony, completeness, and ambiguity. This paper finds that distinguishing between physical and virtual artifacts according to their material and imagined attributes is neither accurate nor useful. This research illustrates how virtual artifacts can obtain the qualities of their physical counterparts and vice versa. It also demonstrates how a new meta-artifact can emerge from the inclusion and unification of its material and imagined components. In conclusion, the paper calls for a seamless continuity in the representation and management of physical and virtual artifacts as a prerequisite to the success of: (1) computer-supported collaborative design processes, (2) academic instruction dealing with making and artifact building, and (3) executive policies in architectural practice addressing the management of architectural documents.

source Cyber-Real Design [Conference Proceedings / ISBN 83-905377-2-9] Bialystock (Poland), 23-25 April 1998, pp. 141-145
summary In a chain of "real - perceived - imagined space" the computer reduces to a uniform model of only real and imagined space. It cannot undertake man's function or it cannot build the perception model. However, perception assumes physiological perception, psychological estimation and understanding, and emotional ho-experience. For a person the seizing of space during perception is constructing temporary spatial images and their development. The communicative relations of the person with environment are established during revealing internal and external structural communications and the interior represents the message, unwrapped in space and perceived in time. The real space is formed under influence of the sum of conceptual restrictions. The character of these restrictions depends on a super idea, a type of an initial situation, character of installations and on social-cultural stereotypes of the author. Without this stage transition to real architectural object is impossible. Result of activity of an architect at this stage becomes creation hypothetical cyberspace, with its own peculiarities and laws.

title Extending spatial DSS with spatial choice models of multipurpose shopping trip behaviour
source Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary Spatial choice or interaction models have been widely used in spatial DSS or customised GIS for analysing the impacts of retail location plans. The models typically used, however, do not account for spatial agglomeration effects on spatial choice behaviour. This study develops a model system for analysing the impacts of retail plans based on a choice model of multipurpose behaviour developed in earlier work. The model system is implemented in the spatial DSS called Location Planner. An empirical study demonstrates the empirical estimation and use of the model for analysing the impacts of an expansion of floor space in the major shopping centre of a middle-sized city in The Netherlands. The results indicate that agglomeration effects as predicted by the model can have substantial impacts on the performance of retail systems. Therefore, it is argued that when incorporated in a spatial DSS, the more complex models have the potential to improve the use of these systems for impact analysis.

title Putting It All Together: Towards a Pattern Language for Interaction Design Reports
source ACM SIGCHI Bulletin 1998 v.30 n.1 pp.17-23
summary Pattern languages are representations that have been used in architecture and urban design for about twenty years. They focus on the interaction between physical form and social behavior, and express design solutions in an understandable and generalizable form. But pattern languages are not simply set of patterns intended to be universally applied; instead, they are actually meta-languages which, when used in a particular situations, generate situated design languages. This report describes a CHI 97 workshop which explored the utility of pattern languages for interaction design. We discuss the workshop's rationale, the structure and process of the workshop, and some of the workshop's results. In particular, we describe some patterns developed as part of the workshop, and our consequent reflections on the use of patterns and pattern languages as lingua franca for interaction design. This report concludes with a bibliography on pattern languages and related matters that spans architecture, software design, and organizational design.

title Cooperation Between Reactive 3D Objects and a Multimodal X Window Kernel for CAD
source Bunt, H., Beun, R.J., Borghuis, T. (Eds.). Multimodal Human-Computer Communication : Systems, Techniques, and Experiments. Berlin : Springer
summary From the early steps of sketching to final engineering, a frequent and very important activity in designing objects is to perform graphical and spatial simulations to solve the constraints on the objects which are being designed. But when we analyse work situations involving the use of CAD systems, it is today an acknowledged fact that these tools are not helpful to perform these types of simulations. While knowledge modeling based on form feature concepts already offers some possibilities for attaching behaviour to objects, the simulation activity requires in addition a `real time' and `intelligent' management of the interactions between the 3D virtual objects and the CAD user. Our general purpose is to study how future CAD systems could be improved to achieve the simulation steps of object design. In this context we present some issues concerning the cooperation between a model of reactive 3D objects and a multimodal X Window kernel. We have developed a prototype of a system where objects with reactive behaviour can be built, and with which the user can interact with a combination of graphical actions and vocal commands. This prototype is used to evaluate the feasability and the usefulness of the integration of such techniques in futur applications that would be used by object designers in a real working context. We describe the current state of this system and the planned improvements.

title The architectural aspect of designing space in virtual environments
source University of Strathclyde, Dept. of Architecure and Building Science
summary This thesis deals with the architectural aspect of virtual environment design. It aims at proposing a framework, which could inform the design of three-dimensional content for defining space in virtual environments, in order to aid navigation and wayfinding. The use of such a framework in the design of certain virtual environments is considered necessary for imposing a certain form and structure to our spatial experience in there.

Firstly, this thesis looks into literature from the fields of architectural and urban design theory, philosophy, environmental cognition, perceptual psychology and geography for the purpose of identifying a taxonomy of spatial elements and their structure in the real world, on the basis of the way that humans think about and remember real environments. Consequently, the taxonomy, proposed for space in the real world is adapted to the intrinsic characteristics of space in virtual environments, on the basis of human factors aspects of virtual reality technology. As a result, the thesis proposes a hypothetical framework consisting of a taxonomy of spatial and space-establishing elements that a virtual environment may comprise and of the possible structure of these elements.

Following this framework, several pilot virtual environments are designed, for the purpose of identifying key design issues for evaluation. As it was impossible to evaluate the whole framework, six specific design issues, which have important implications for the design of space in virtual environments, are investigated by experimental methods of research. Apart from providing answers to these specific design issues, the experimental phase leads to a better understanding of the nature of space in virtual environments and to several hypotheses for future empirical research.

title Supporting information navigation in generative design systems
source Camegie Mellon University, School of Architecture
summary Generative design systems make it easier for designers to generate and explore design altematives, but the amount of information generated during a design session can become very large. Intelligent navigation aids are needed to enable designers to access the information with ease. Such aids may improve the usability of generative design systems and encourage their use in architectural practice. This dissertation presents a comprehensive approach to support navigation in generative design systems. This approach takes account of studies related to human spatial cognition, wayfinding in physical environments, and information navigation in electronic media. It contains a general model of design space, basic navigation operations, and principles for designing navigation support. The design space model describes how the space may grow and evolve along predictable dimensions. The basic operations facilitate navigation activities in this multi-dimensional design space. The design principles aim at guiding system developers in creating navigation utilities tailored to the needs of individual design systems. This approach is validated through prototype implementations and limited pilot usability studies. The validity of the design space model and basic navigation operations is examined through the development of a design space navigation framework that encapsulates the model and operations in a software environment and provides the infrastructure and mechanisms for supporting navigation. Three prototype navigation tools are implemented using this framework. These tools are subjected to usability studies. The studies show that these tools are easy to leam and are efficient in assisting designers locating desired information. In summary, it can be demonstrated that through the prototype implementations and usability studies, this approach offers sufficient support for the design and implementation of navigation aids in a generative design system. The research effort is a pioneer study on navigation support in generative design systems. It demonstrates why navigation support is necessary; how to provide the support; and what types of user interaction it can offer. This research contributes to information navigation studies not only in the specific domain of generative design system research, but also in the general field of human-computer interaction.

summary Architectural design teaching using computers has been a preoccupation of CECA since 1991. All design tutors provide their students with a set of models and ways to form, and we have explored a set of approaches including cellular automata, genetic programming ,agent based modelling and shape grammars as additional tools with which to explore architectural ( and architectonic) ideas.This paper discusses the use of genetic programming (G.P.) for applications in the field of spatial composition. CECA has been developing the use of Genetic Programming for some time ( see references ) and has covered the evolution of L-Systems production rules( coates 1997, 1999b), and the evolution of generative grammars of form (Coates 1998 1999a). The G.P. was used to generate three-dimensional spatial forms from a set of geometrical structures .The approach uses genetic programming with a Genetic Library (G.Lib) .G.P. provides a way to genetically breed a computer program to solve a problem.G. Lib. enables genetic programming to define potentially useful subroutines dynamically during a run .* Exploring a shape grammar consisting of simple solid primitives and transformations. * Applying a simple fitness function to the solid breeding G.P.* Exploring a shape grammar of composite surface objects. * Developing grammarsfor existing buildings, and creating hybrids. * Exploring the shape grammar of abuilding within a G.P.We will report on new work using a range of different morphologies ( boolean operations, surface operations and grammars of style ) and describe the use of objective functions ( natural selection) and the "eyeball test" ( artificial selection) as ways of controlling and exploring the design spaces thus defined.

title Spatial Orientation and Wayfinding in Large Scale Virtual Spaces
source Presence: Teleoperators and Virtual Environments, 7 (2), pp. 101-107
summary Just as the Pathfinder used the lake and the oak tree to reconstruct his environment, so do we structure our environment with streets and houses, landmarks and guiding principles to aid spatial orientation and wayfinding. The basic process of navigation-extracting information, forming mental representations, and using that representation for route planning and moving about-transcends the physical elements of the environment itself. In practice, we use whatever the environment gives us to solve navigation problems as they arise, in the process, continually refining and updating our internal model of the external environment. Although the virtual environments we speak of may be vastly different in their appearance from the Pathfinder's world, the principles underlying spatial orientation and wayfinding in large-scale virtual spaces have many commonalities.

title A Case Study on a Neighbourhood unitPlanning in Ankara-Turkey
source Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary In this study a neighborhood unit which contains 700 dwelling of 6 different types is planned in Ankara- TURKEY. The site is at the outside of the boundaries of the main city and it is designed with regard toall daily facilities exept the workplace. This case study is limited to neighborhood units of 3500 persons and incorporates a kindergarden, primary school, health center, shopping center, playgrounds, playfieldand library within the housing area. The proposed settlement is planned or the middle, and uppermiddle socio-economic classes. The housing project provides its users 6 types of dwellings for their choice: 2 from the houses and 4 from the appartment blocks. They can decide the most suitable typeconsidering the finance and use. The houses are clustered together to encourage social and economical relation of the people living in them.

title Visual Communication in Urban Planning and Urban Design
source Working Paper 2; Centre for Advanced Spatial Analysis Working Papers; London; June 1998
summary This Case Study documents the current status of visual communication in urban design and planning. Visual communication is examined through discussion of standalone and network media, specifically concentrating on visualisation on the World Wide Web (WWW). First, we examine the use of Solid and Geometric Modelling for visualising urban planning and urban design. This report documents and compares examples of the use of Virtual Reality Modelling Language (VRML) and proprietary WWW based Virtual Reality modelling software. Examples include the modelling of Bath and Glasgow using both VRML 1.0 and 2.0. The use of Virtual Worlds and their role in visualising urban form within multi-user environments is reviewed. The use of Virtual Worlds is developed into a study of the possibilities and limitations of Virtual Internet Design Arena's (ViDA's), an initiative undertaken at the Centre for Advanced Spatial Analysis, University College London. The use of Virtual Worlds and their development towards ViDA's is seen as one of the most important developments in visual communication for urban planning and urban design since the development plan. Secondly, the role of photorealistic media in the process of communicating plans is examined. The process of creating photorealistic media is documented, and examples of the Virtual Streetscape and Wired Whitehall Virtual Urban Interface System are provided. The conclusion is that, although the use of photo-realistic media on the WWW provides a way to visually communicate planning information, its use is limited. The merging of photorealistic media and solid geometric modelling in the creation of Augmented Reality is reviewed. Augmented Reality is seen to provide an important step forward in the ability quickly and easily to visualise urban planning and urban design information. Third, the role of visual communication of planning data through GIS is examined in terms of desktop, three dimensional, and Internet based GIS. The evolution to Internet GIS is seen as a critical component in the development of virtual cities that will allow urban planners and urban designers to visualise and model the complexity of the built environment in networked virtual reality. Finally, a viewpoint is put forward of the Virtual City, linking Internet GIS with photorealistic multi-user Virtual Worlds. At present there are constraints on how far virtual cities can be developed, but a view is provided on how these networked virtual worlds are developing to aid visual communication in urban planning and urban design.
