summary	3-D models and computer graphics with its visual characteristics enables easier understanding of various information. Up until now 3-D models and computer graphics has not been used for the analysis of city information due to its high cost and the need for special techniques. Currently, we have discovered new technology in hyper medium based on network technology and lower costs. This paper focuses on the construction of an interactive and visual 3-D city information system, aiming at the ‘idea processor’ for research and analysis of city planning and market research. We have discovered the requirements necessary for the City Information Visualizer system. Using this technology we will construct the prototype system of the 3-D City Information Visualizer. This system is based on the personal computer and the Client/Server system. The system is then applied to practical city analysis. This paper presents the prototype system and its evaluation in a real project.

title	Computer Graphics: Assistance for Archaeological Hypotheses

summary	This paper is a contribution to the domain of computer tools for architectural and archeological restitution of ancient buildings. We describe an application of these tools to the modeling of the 14th century AD. Thermae of Constantin in Arles, south of France. It was a diploma project in School of Architecture of MarseilleLuminy, and took place in a context defined in the European ARELATE project. The general objective of this project is to emphasize the archeological and architectural heritage of the city of Arles; it aims, in particular, to equip the museum of ancient Arles with a computer tool enabling the storage and consultation of archaeological archives, the communication of information and exchange by specialized networks, and the creation of a virtual museum allowing a redescription of the monuments and a “virtual” visit of ancient Arles. Our approach involves a multidisciplinary approach, calling on architecture, archeology and computer science. The archeologist’s work is to collect information and interpret it; this is the starting point of the architect’s work who, using these elements, suggests an architectural reconstruction. This synthesis contains the functioning analysis of the structure and building. The potential provided by the computer as a tool (in this case, the POV-Ray software) with access to several three-dimensional visualizations, according to hypotheses formulated by the architect and archaeologists, necessitates the use of evolutive models which, thanks to the parametrization of dimensions of a building and its elements, can be adapted to all the changes desired by the architect. The specific contribution of POV-Ray in architectural reconstruction of thermae finds its expression in four forms of this modeling program, which correspond to the objectives set by the architect in agreement with archeologists: (a) The parametrization of dimensions, which contributes significantly in simplifying the reintervention process of the architectural data base; (b) Hierarchy and links between variables, allowing “grouped” modifications of modelized elements in order to preserve the consistency of the architectural building’s morphology; (c) The levels of modeling (with or without facing, for example), which admit of the exploration of all structural and architectural trails (relationship form/ function); and, (d) The “model-type,” facilitating the setting up of hypotheses by simple scaling and transformation of these models (e.g., roofing models) on an already modelled structure. The methodological validation of this modeling software’s particular use in architectural formulation of hypotheses shows that the software is the principal graphical medium of discussion between architect and archaeologist, thus confirming the hypotheses formulated at the beginning of this project.

title	The Impact of Virtual Reality on the Design Process
doi	https://doi.org/10.52842/conf.acadia.1998.138
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. 138-163
summary	Sketching, either hand or computer generated, along with other traditional visualization tools such as perspective drawing have difficulty in correctly representing three dimensional objects. Even physical models, in architecture, suffer in this regard because of inevitable scaling. The designer finds himself cut off from the reality of the object and is prone to misinterpretations of the object and its surrounding space and to resulting design errors. These are sometimes not perceived until too late, once the object has been constructed. Traditional tools use 2D media to represent 3D objects and only manage to introduce the third dimension in a limited manner (perspectives, not only tedious to construct, are static). This scenario affects the design process, particularly the cycle of proposal, verification and correction of design hypotheses as well as the cognitive aspects that condition the designer’s visualization of the designed object. In most cases, computer graphics mimic, through its interface, the traditional way of doing things. The architectural model is parametricized with little regard for visualization. No allowance is made for the change in the medium of graphic representation. Moreover, effort is not made to capitalize on the advantages of numerical calculation to propose new interfaces and new dimensions in object visualization. Virtual Reality (VR), seen not only as technology but as experience, brings the 3D object, abstractly viewed by traditional means, into clearer focus and provides us with these new dimensions. Errors due to abstracted representation are reduced since the interface is always three dimensional and the interactions intuitively made in real time thus allowing the designer to experience the presence of the designed object very quickly. At the École de design industriel of the Faculté d’aménagement, we have run tests using non-immersive VR–one passive (comprehension) and another active (design). This project, involving a group of 72 students during a period of six weeks (6h/week), aimed at analyzing the impact of VR as a visualization tool on the design process versus traditional tools. The results, described in this presentation, shed light on the effect of VR on the creative process as such, as well as on the quality of the results produced by that process.

title	A Model for Integrated Spatial and Structural Design of Buildings
doi	https://doi.org/10.52842/conf.caadria.1998.123
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. 123-132
summary	Recent advances in computer graphics and 3D user interfaces have enabled the emergence of 3D sketch modeling as a viable approach to architectural design, especially in the early schematic phase. This paper describes how a system can be built and used which integrates the capabilities of a good structural analysis system in the user-friendly working environment of a design-oriented modeling program. The structure of a building model as seen by finite element algorithms is a schematic idealization of the building's physical structure into nodes, elements, internal releases, boundary conditions, and loads. The more familiar architectural model used for design visualization represents spatial elements such as roofs, floors, walls, and windows. Rather than treat these models independently, the structural model can be defined in relation to the architectural as a virtual model with inherited common characteristics and additional relational and attribute information, using feature-based geometry data structures to organize topological intelligence in the spatial model. This provides the basis for synchronous modification of structural and architectural aspects of the design.

summary	Particular design approaches must be taught in order to take advantage of the strengths of computers in design rather than attempting to make computers conform to methods developed as by-products of manual design techniques. For the last three years our team of faculty teaching the second year design studio has been trying different approaches to the use of computers in design, in order to find the advantages and opportunities especially suited to electronic media. There are several projects during the semester which use computers at different stages of the design process. One of these projects, called “A Spatial Sequence,” uses information from a previous project as well as the knowledge from the computer class in parallel to design studio. The project asked students to create spatial archetypes based on the work of well-known architects. They explore the following topics as represented in the work of one particular architect: relationships of major spaces/minor spaces, approach/entry, and transition/threshold. Following the analysis, they create digital models to explore the spaces formed by their archetypes. Before committing to a physical study model, they look at the transitions between spaces by creating a sequence using the digital model and producing a series of shots through the digital model to show the flow of spaces. The use of computer through the process accelerates the options available to explore a sequence of elements, while simultaneously giving them a window to look into the spaces they have created. This hybridized approach of precedent analysis, digital modeling, and physical modeling was uniquely suited to the studio problem.

title	Making Models Architectural: Protean Representations to Fit Architects’ Minds
doi	https://doi.org/10.52842/conf.acadia.1998.354
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. 354-365
summary	A rich vocabulary has evolved for describing architecture. It serves not only as a means of communication, but also as an embodiment of concepts relating to form, space, structure, function, mood, and symbolism. We architects not only speak in terms of walls, rooms, roofs, arches, etc., we see in terms of them and think in terms of them, as well. Such concepts are integral to our ability to design. Typical CAD representations, however, are based on geometric/mathematical elements like points, lines, planes, and symbols. Even more experimental approaches like parametric shapes or procedural assemblies correspond poorly to architectural elements, and seldom lend themselves well to making conceptual changes that would allow exploration of design alternatives. Small wonder some architecture schools experience a division between computer and studio courses, or even between computer and studio faculty. Different ways of talking and thinking are involved. The concepts involved are often mutually exclusive. This paper discusses an attempt to address this conceptual mismatch, using what are termed “protean” (meaning “very changeable”) elements. These are high-level elements corresponding to architectural concepts like “wall,” or “dome.” They each have parameters appropriate for the particular type of element they represent, and produce the polyhedra necessary for graphics based on these parameters. A system is being implemented to allow models to be constructed using these elements. The protean elements form a loosely structured model, in which some elements hierarchically contain others, and some elements are essentially freestanding, being created and manipulated independently of other elements. Characteristics of protean element are discussed, including the underlying object-oriented structure, the relationship between elements and graphics, and functions associated with the objects. A scheme is explained whereby all parts of a design can be represented even when the design includes extremely unusual forms not conforming to predictable classes of elements. The necessary support framework is also discussed; general flow of the system and mechanisms for viewing the model and editing subcomponents are explained. The current status of the project, and intentions for future work are discussed. The project has been partially implemented, and the necessary framework to support the system is mostly complete.

summary	VRML offers a high potential for product presentation: Instead of regarding flat, static pictures, configurable and animated 3D models embedded in entertaining environments provide a new way of product presentation. But seriously using VRML for this application domain means facing several challenges. We discuss these issues by using the Virtual Design Exhibition as a showcase. In this exhibition seven interior design companies show products with high aesthetic quality. We discuss how these aesthetics influence the VRML presentation and give some guidelines resulting from our experience.

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	DTS Printer: Spatial Inkjet Printing
doi	https://doi.org/10.52842/conf.acadia.2021.454
source	ACADIA 2021: Realignments: Toward Critical Computation [Proceedings of the 41st Annual Conference of the Association of Computer Aided Design in Architecture (ACADIA) ISBN 979-8-986-08056-7]. Online and Global. 3-6 November 2021. edited by S. Parascho, J. Scott, and K. Dörfler. 454-459.
summary	Inkjet printing has become abundantly available to businesses, offi ces, and households ever since its commercialization in the late 1980s. Although roughly forty years have passed, the desktop printer is still limited to printing on thin fl at surfaces, mainly paper (Mills 1998). On the other hand, while larger fl atbed printing technology does offer printing on a wide-range of substrates of various thicknesses, it is limited to 2-axis printing and is mainly used for large scale commercial applications due to high machine costs. Motivated by the ambition of printing on irregular surfaces of varied mediums, improving upon high price points of existing fl at-bed printing machines, and contributing to the public knowledge of distributed manufacturing, the Direct-To-Substrate (DTS) printer is an exploration into an integrated z-axis within inkjet printing. To realign a familiar technology used by many and hack it for the purposes of expanded capabilities, the DTS allows a user to manufacture a three-dimensional artifact and later print graphics directly upon said geometry using the same machine. To remain as accessible as possible, the DTS printer is a computer-numerically-controlled desktop machine made from common, sourceable hardware parts with a tool-changeable end effector, that currently accepts a Dremel tool as a router, and a hacked inkjet cartridge

title	Possible Futures in Computer Art Generation
source	International Conference on Generative Art
summary	Years of trying to create an "Image Idea Generator" program have convinced me that the perfect solution would be to have an artificial artistic person, a design slave. This paper describes how I came to that conclusion, realistic alternatives, and briefly, how it could possibly happen. 1. The history of Repligator and Gliftic 1.1 Repligator In 1996 I had the idea of creating an “image idea generator”. I wanted something which would create images out of nothing, but guided by the user. The biggest conceptual problem I had was “out of nothing”. What does that mean? So I put aside that problem and forced the user to give the program a starting image. This program eventually turned into Repligator, commercially described as an “easy to use graphical effects program”, but actually, to my mind, an Image Idea Generator. The first release came out in October 1997. In December 1998 I described Repligator V4 [1] and how I thought it could be developed away from simply being an effects program. In July 1999 Repligator V4 won the Shareware Industry Awards Foundation prize for "Best Graphics Program of 1999". Prize winners are never told why they won, but I am sure that it was because of two things: 1) Easy of use 2) Ease of experimentation "Ease of experimentation" means that Repligator does in fact come up with new graphics ideas. Once you have input your original image you can generate new versions of that image simply by pushing a single key. Repligator is currently at version 6, but, apart from adding many new effects and a few new features, is basically the same program as version 4. Following on from the ideas in [1] I started to develop Gliftic, which is closer to my original thoughts of an image idea generator which "starts from nothing". The Gliftic model of images was that they are composed of three components: 1. Layout or form, for example the outline of a mandala is a form. 2. Color scheme, for example colors selected from autumn leaves from an oak tree. 3. Interpretation, for example Van Gogh would paint a mandala with oak tree colors in a different way to Andy Warhol. There is a Van Gogh interpretation and an Andy Warhol interpretation. Further I wanted to be able to genetically breed images, for example crossing two layouts to produce a child layout. And the same with interpretations and color schemes. If I could achieve this then the program would be very powerful. 1.2 Getting to Gliftic Programming has an amazing way of crystalising ideas. If you want to put an idea into practice via a computer program you really have to understand the idea not only globally, but just as importantly, in detail. You have to make hard design decisions, there can be no vagueness, and so implementing what I had decribed above turned out to be a considerable challenge. I soon found out that the hardest thing to do would be the breeding of forms. What are the "genes" of a form? What are the genes of a circle, say, and how do they compare to the genes of the outline of the UK? I wanted the genotype representation (inside the computer program's data) to be directly linked to the phenotype representation (on the computer screen). This seemed to be the best way of making sure that bred-forms would bare some visual relationship to their parents. I also wanted symmetry to be preserved. For example if two symmetrical objects were bred then their children should be symmetrical. I decided to represent shapes as simply closed polygonal shapes, and the "genes" of these shapes were simply the list of points defining the polygon. Thus a circle would have to be represented by a regular polygon of, say, 100 sides. The outline of the UK could easily be represented as a list of points every 10 Kilometers along the coast line. Now for the important question: what do you get when you cross a circle with the outline of the UK? I tried various ways of combining the "genes" (i.e. coordinates) of the shapes, but none of them really ended up producing interesting shapes. And of the methods I used, many of them, applied over several "generations" simply resulted in amorphous blobs, with no distinct family characteristics. Or rather maybe I should say that no single method of breeding shapes gave decent results for all types of images. Figure 1 shows an example of breeding a mandala with 6 regular polygons: Figure 1 Mandala bred with array of regular polygons I did not try out all my ideas, and maybe in the future I will return to the problem, but it was clear to me that it is a non-trivial problem. And if the breeding of shapes is a non-trivial problem, then what about the breeding of interpretations? I abandoned the genetic (breeding) model of generating designs but retained the idea of the three components (form, color scheme, interpretation). 1.3 Gliftic today Gliftic Version 1.0 was released in May 2000. It allows the user to change a form, a color scheme and an interpretation. The user can experiment with combining different components together and can thus home in on an personally pleasing image. Just as in Repligator, pushing the F7 key make the program choose all the options. Unlike Repligator however the user can also easily experiment with the form (only) by pushing F4, the color scheme (only) by pushing F5 and the interpretation (only) by pushing F6. Figures 2, 3 and 4 show some example images created by Gliftic. Figure 2 Mandala interpreted with arabesques Figure 3 Trellis interpreted with "graphic ivy" Figure 4 Regular dots interpreted as "sparks" 1.4 Forms in Gliftic V1 Forms are simply collections of graphics primitives (points, lines, ellipses and polygons). The program generates these collections according to the user's instructions. Currently the forms are: Mandala, Regular Polygon, Random Dots, Random Sticks, Random Shapes, Grid Of Polygons, Trellis, Flying Leap, Sticks And Waves, Spoked Wheel, Biological Growth, Chequer Squares, Regular Dots, Single Line, Paisley, Random Circles, Chevrons. 1.5 Color Schemes in Gliftic V1 When combining a form with an interpretation (described later) the program needs to know what colors it can use. The range of colors is called a color scheme. Gliftic has three color scheme types: 1. Random colors: Colors for the various parts of the image are chosen purely at random. 2. Hue Saturation Value (HSV) colors: The user can choose the main hue (e.g. red or yellow), the saturation (purity) of the color scheme and the value (brightness/darkness) . The user also has to choose how much variation is allowed in the color scheme. A wide variation allows the various colors of the final image to depart a long way from the HSV settings. A smaller variation results in the final image using almost a single color. 3. Colors chosen from an image: The user can choose an image (for example a JPG file of a famous painting, or a digital photograph he took while on holiday in Greece) and Gliftic will select colors from that image. Only colors from the selected image will appear in the output image. 1.6 Interpretations in Gliftic V1 Interpretation in Gliftic is best decribed with a few examples. A pure geometric line could be interpreted as: 1) the branch of a tree 2) a long thin arabesque 3) a sequence of disks 4) a chain, 5) a row of diamonds. An pure geometric ellipse could be interpreted as 1) a lake, 2) a planet, 3) an eye. Gliftic V1 has the following interpretations: Standard, Circles, Flying Leap, Graphic Ivy, Diamond Bar, Sparkz, Ess Disk, Ribbons, George Haite, Arabesque, ZigZag. 1.7 Applications of Gliftic Currently Gliftic is mostly used for creating WEB graphics, often backgrounds as it has an option to enable "tiling" of the generated images. There is also a possibility that it will be used in the custom textile business sometime within the next year or two. The real application of Gliftic is that of generating new graphics ideas, and I suspect that, like Repligator, many users will only understand this later. 2. The future of Gliftic, 3 possibilties Completing Gliftic V1 gave me the experience to understand what problems and opportunities there will be in future development of the program. Here I divide my many ideas into three oversimplified possibilities, and the real result may be a mix of two or all three of them. 2.1 Continue the current development "linearly" Gliftic could grow simply by the addition of more forms and interpretations. In fact I am sure that initially it will grow like this. However this limits the possibilities to what is inside the program itself. These limits can be mitigated by allowing the user to add forms (as vector files). The user can already add color schemes (as images). The biggest problem with leaving the program in its current state is that there is no easy way to add interpretations. 2.2 Allow the artist to program Gliftic It would be interesting to add a language to Gliftic which allows the user to program his own form generators and interpreters. In this way Gliftic becomes a "platform" for the development of dynamic graphics styles by the artist. The advantage of not having to deal with the complexities of Windows programming could attract the more adventurous artists and designers. The choice of programming language of course needs to take into account the fact that the "programmer" is probably not be an expert computer scientist. I have seen how LISP (an not exactly easy artificial intelligence language) has become very popular among non programming users of AutoCAD. If, to complete a job which you do manually and repeatedly, you can write a LISP macro of only 5 lines, then you may be tempted to learn enough LISP to write those 5 lines. Imagine also the ability to publish (and/or sell) "style generators". An artist could develop a particular interpretation function, it creates images of a given character which others find appealing. The interpretation (which runs inside Gliftic as a routine) could be offered to interior designers (for example) to unify carpets, wallpaper, furniture coverings for single projects. As Adrian Ward [3] says on his WEB site: "Programming is no less an artform than painting is a technical process." Learning a computer language to create a single image is overkill and impractical. Learning a computer language to create your own artistic style which generates an infinite series of images in that style may well be attractive. 2.3 Add an artificial conciousness to Gliftic This is a wild science fiction idea which comes into my head regularly. Gliftic manages to surprise the users with the images it makes, but, currently, is limited by what gets programmed into it or by pure chance. How about adding a real artifical conciousness to the program? Creating an intelligent artificial designer? According to Igor Aleksander [1] conciousness is required for programs (computers) to really become usefully intelligent. Aleksander thinks that "the line has been drawn under the philosophical discussion of conciousness, and the way is open to sound scientific investigation". Without going into the details, and with great over-simplification, there are roughly two sorts of artificial intelligence: 1) Programmed intelligence, where, to all intents and purposes, the programmer is the "intelligence". The program may perform well (but often, in practice, doesn't) and any learning which is done is simply statistical and pre-programmed. There is no way that this type of program could become concious. 2) Neural network intelligence, where the programs are based roughly on a simple model of the brain, and the network learns how to do specific tasks. It is this sort of program which, according to Aleksander, could, in the future, become concious, and thus usefully intelligent. What could the advantages of an artificial artist be? 1) There would be no need for programming. Presumbably the human artist would dialog with the artificial artist, directing its development. 2) The artificial artist could be used as an apprentice, doing the "drudge" work of art, which needs intelligence, but is, anyway, monotonous for the human artist. 3) The human artist imagines "concepts", the artificial artist makes them concrete. 4) An concious artificial artist may come up with ideas of its own. Is this science fiction? Arthur C. Clarke's 1st Law: "If a famous scientist says that something can be done, then he is in all probability correct. If a famous scientist says that something cannot be done, then he is in all probability wrong". Arthur C Clarke's 2nd Law: "Only by trying to go beyond the current limits can you find out what the real limits are." One of Bertrand Russell's 10 commandments: "Do not fear to be eccentric in opinion, for every opinion now accepted was once eccentric" 3. References 1. "From Ramon Llull to Image Idea Generation".

title	Replacement and Transformation as a Key to Schematic Design Thinking - 3-D Modeling System which Supports Design Thinking
doi	https://doi.org/10.52842/conf.caadria.1998.365
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. 365-374
summary	This paper analyses a prototype of a 3D modeling system that can support schematic design development and begins with very abstract representation elaborates it step by step into a detailed representation. Using Mitchell's concept of a TOPDOWN system for 2D sketches as the basis, the authors proposed a design process model and a prototype that allows both bottom up additive processes in exploring the design frame and top down processes for the design refinement of each building element. Various utilities of replacing and transforming graphic objects as well as those that can control shapes and the location of those objects with construction lines have been proposed. The authors discussed possible use of the system and topics for future study by reviewing case studies.

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	The paper discusses conceptual issues, goals and preliminary results of an on-going research which aims at building a Decision Support System for public housing environmental oriented maintenance and management in a city in Southern Italy, Bari. Traditional post-war Italian housing policies are compared with more recent approaches in the field, pointing out the change from quantitative, aggregated, more simple building problems and relatedapproaches to qualitative, differentiated, complex ones integrating social, economic and environmental dimensions with the aim of regenerating deteriorated residential areas. The paper claims for the need shift, both in the human and computer areas, from traditional quantitative models to new approaches able to manage also qualitative variables, temporal dynamics, emergencies, and intentionality, since they appear key aspects of the real world to be modelled. The housing estate of Bari and its needs of maintenance and management are examined, eliciting essential related knowledge using the interview technique. The clear orientation towards sustainable policies for urban regeneration, at a local, national, and Community level, is also considered. The innovative and collaborative nature of such policies and the attention to be paid to the social aspects ofthe problem require a complex DSS, integrating various kind of hypertexts, information systems and case-based fuzzy expert systems, whose main aims, functions, software and general organisation are outlined in the paper.

source	II Seminario Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings / ISBN 978-97190-0-X] Mar del Plata (Argentina) 9-11 september 1998, pp. 212-217
summary	The present work is part of the exposition "Francesco Tamburini, La ConstrucciÛn del Espacio del Poder I", exhibited in Rivadavia Cultural Center ( Rosario city), and in Casa Rosada Museum during 1997. The Exposition is based on an investigation program of the space that involves Casa Rosada, determining this space as the first piece of its collection. In 1995, when a group of argentines where visiting the picture gallery Pianetti (Jesi, Italy) there have been found some watercolours of Francesco Tamburini (1846-1890), planner of the main faÁades of the Government and author of many works. These watercolours have great value for architecture, and unknown by public, they have been the starting point of the Exposition. Among these argentines was Roberto De Gregorio architect, historian teacher of this school of architecture, and in charge of the historical investigation. C.I.A.D.'s specific work consists in converting in digital data Casa Rosada's faÁades. The two first stages, already completed, finished on the digital data conversion of facades, in front of Plaza de Mayo and Rivadavia street, with presidential access esplanade. Actually the work is centred on the two facades left and on the elaboration of an electronic model for the edition of a CD-ROM containing the information of the exposition.

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.

summary	Neighborhood scale planning and design in many areas of the United States has been evolving toward a system of negotiated priorities and agreements. Common models include public workshops and design 'charrettes' which bring diverse stakeholders (citizens, land owners, developers, consultantsand public officials, for example) together to develop a mutually acceptable plan. Crucial to the quality and effectiveness of the outcome are decision support tools that help this diverse audience understand, communicate, collaborate and make decisions about complex and often emotional issuesof land use and design. Net Energy Communities (NEC), the project summarized in this paper, creates a suite of computer based tools for this purpose. NEC links three types of computer software — the spatial data manipulation, modeling and visualization capabilities of Geographic Information Systems (GIS), the illustration and information retrieval capabilities of multimedia relational databases and, the simulation and comparison capabilities of spreadsheet-based calculation models;into four tools — a site modeller, an elements of neighborhood database, a scenario modeller and ascenario calculator. This paper reports on the NEC project as an example of decision support tools for public participation using illustrations and examples from a 420 acre demonstration neighborhood design in progress for the City of Corvallis, Oregon, USA.

source	II Seminario Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings / ISBN 978-97190-0-X] Mar del Plata (Argentina) 9-11 september 1998, pp. 192-197
summary	Colonia del Sacramento (capital of Colonia department, in Uruguay) has been registered in the list of the Convention Heritage concerning the protection of worldwide cultural and natural heritage. The registration on this list (December 6th 1995) confirms the exceptional and universal value of a cultural or natural places which deserves protection for the whole humanity. The ancient Colonia del Sacramento founded in 1680 by Portugal, was a commercial and military site leading role of the historical controversy between Spain and Portugal. Main place of wars and treaties during a century, it keeps an urban design, unique in the area and valuable architectonical testimonies of different periods of this rich past, with a simple, popular profile. This work has been effected within the Clemente Estable Found 1996, which is promoted by National Council of Scientific and Technical Research (CONICYT). Through virtual reality techniques, a three-dimensional model of Colonia del Sacramento city was built as it was in its period of prosperity (around 1762). For the achievement of this digital maquette, a great deal of written and graphic information was compiled and processed. This information was organized in an inventory way (with numerous readings and searches). The inventory and the digital maquette were joined in a multimedia application (CD-ROM) which allows potential users to move through virtual city and friendly and interactively consult images, graphics and texts.

summary	Computers have helped bring architectural education to a digital crossroads. This new tool is effecting architectural education on numerous levels, from the simplest word processing of research papers to more complex interactive modeling. This casestudy paper will focus on the new and changing role of the computer in the design studio. In this case, the approach to integrating the computer into the studio revolves around its application simply as another tool for a designer’s use. Clearly, the use of computers in design studios is not a new development. However, as the computer’s use in design education is not yet widespread, a dialogue about methods of application is valuable for design educators. The intent behind computer use in this case was not to replace traditional design methods but to complement and enhance them. In this spirit, this case study focuses on the use of computers to investigate two aspects of design that are challenging to model: light and time. In the studios to be examined here, students were required to explore their designs with both traditional tools (sketches on trace, physical study models as well as final finish models, etc.) and with newer digital tools (lighting simulation programs, threedimensional modeling programs, and animation). Students worked in teams in most cases. The computer was used both as a design tool as well as a representational tool, with varying degrees of success, depending on the student’s expertise, comfort using the computer as a design tool and access to appropriate hardware and software. In the first studio case study, the “new” medium of the computer was a perfect complement for the focus of the studio, entitled “Space and Light.” In addition to utilizing large scale physical models traditionally used for lighting design, three-dimensional computer models using Lightscape enriched the design results. Both sets of tools were vital for the design processes of the studio assignments. In the second studio case study, a traditional fourth year studio was required to use the computer to explore the dimension of time in their designs, which in this case translated into animation modeling. Integrating the computer into the design studio promises to be a complex task. As these examples will illustrate, the advantages and the disadvantages require continual balancing. Philosophical disagreement, potential discomfort, or a general lack of knowledge of digital tools may inhibit design educators from testing the potential of these ever-changing tools. Despite the challenges, this case study reveals the educational value of continued experimental use of digital tools in the design studio.

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. 276-288
summary	Increasingly, we find ourselves spending more time on a daily basis engaged in a variety of virtual environments, ranging from those discovered when using the stand-alone computer, to more complex distributed networks such as the World Wide Web. Virtual environments are not restricted to the popular and hyped notion of immersive Virtual Reality systems, though, in immersion, such systems provide a dimension of experience sorely lacking in most human-computer interfaces. The design of a diverse range of virtual environments, from textual through to three dimensional, would seem to require insight from those who habitually create immersive experiences, whether real or virtual. The former include architects, the latter the authors of computer games. Virtual environments such as the Internet, and the World Wide Web in particular, are becoming increasingly confusing to navigate. Exploratory behaviour in these environments requires extensive cognitive effort, and often results in disorientation and a sense of anxiety. This paper attempts to address issues of cognitive mapping in virtual environment design, and the exciting role that architects should occupy in the creation of better virtual environments. A virtual environment tool, called WOMBAT, has been developed to discover more about the relationship between real environment and virtual environment navigation and cognitive mapping, and consequently the degree to which concepts and theories from real environment design and cognitive mapping research can be translated to the virtual environment domain. Both a natural environment and an information environment are being investigated using WOMBAT, with the primary interest being the cognitive mapping and wayfinding activities that are exhibited during exploration.
