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.

title Computer Graphics and Architecture: State of the Art and Outlook for the Future
source Computer Graphics, Vol 32, No 1, Feb 1998. pp. 45-48
summary During the three decades since Ivan Sutherland introduced the Sketchpad system, there has been an outpouring of computer graphics systems for use in architecture. In response to this development, most of the major architectural firms around the world have embraced the idea that computer literacy is mandatory for success. We would argue, however, that most of these recent developments have failed to tap the potential of the computer as a design tool. Instead, computers have been relegated largely to the status of drafting instruments, so that the "D" in CAD stands for drafting rather than design. It is important that future architectural design systems consider design as a continuous process rather than an eventual outcome.The advent of computer graphics technology has had an impact on the architectural profession. Computer graphics has revolutionized the drafting process, enabling the rapid entry and modification of designs. In addition, modeling and rendering systems have proven to be invaluable aids in the visualization process, allowing designers to walk through their designs with photorealistic imagery. Computer graphics systems have also demonstrated utility for capturing engineering information, greatly simplifying the analysis and construction of proposed designs. However, it is important to consider that all of these tasks occur near the conclusion of a larger design process. In fact, most of the artistic and intellectual challenges of an architectural design have already been resolved by the time the designer sits down in front of a computer. In seeking insight into the design process, it is generally of little use to revisit the various computer archives and backups. Instead, it is best to explore the reams of sketches and crude balsa models that fill the trash cans of any architectural studio.In architecture, as in most other fields, the initial success of computerization has been in areas where it frees humans from tedious and mundane tasks. This includes the redrawing of floor plans after minor modifications, the generation of largely redundant, yet subtly different engineering drawings and the generation of perspective renderings.We believe that there is a largely untapped potential for computer graphics as a tool in the earlier phases of the design process. In this essay, we argue that computer graphics might play a larger role via applications that aid and amplify the creative process.

title A digital Procedure of Building Construction: A practical project
source AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary In earlier times in which computers have not yet been developed well, there has been some researches regarding representation using conventional media (Gombrich, 1960; Arnheim, 1970). For ancient architects, the design process was described abstractly by text (Hewitt, 1985; Cable, 1983); the process evolved from unselfconscious to conscious ways (Alexander, 1964). Till the appearance of 2D drawings, these drawings could only express abstract visual thinking and visually conceptualized vocabulary (Goldschmidt, 1999). Then with the massive use of physical models in the Renaissance, the form and space of architecture was given better precision (Millon, 1994). Researches continued their attempts to identify the nature of different design tools (Eastman and Fereshe, 1994). Simon (1981) figured out that human increasingly relies on other specialists, computational agents, and materials referred to augment their cognitive abilities. This discourse was verified by recent research on conception of design and the expression using digital technologies (McCullough, 1996; Perez-Gomez and Pelletier, 1997). While other design tools did not change as much as representation (Panofsky, 1991; Koch, 1997), the involvement of computers in conventional architecture design arouses a new design thinking of digital architecture (Liu, 1996; Krawczyk, 1997; Murray, 1997; Wertheim, 1999). The notion of the link between ideas and media is emphasized throughout various fields, such as architectural education (Radford, 2000), Internet, and restoration of historical architecture (Potier et al., 2000). Information technology is also an important tool for civil engineering projects (Choi and Ibbs, 1989). Compared with conventional design media, computers avoid some errors in the process (Zaera, 1997). However, most of the application of computers to construction is restricted to simulations in building process (Halpin, 1990). It is worth studying how to employ computer technology meaningfully to bring significant changes to concept stage during the process of building construction (Madazo, 2000; Dave, 2000) and communication (Haymaker, 2000).In architectural design, concept design was achieved through drawings and models (Mitchell, 1997), while the working drawings and even shop drawings were brewed and communicated through drawings only. However, the most effective method of shaping building elements is to build models by computer (Madrazo, 1999). With the trend of 3D visualization (Johnson and Clayton, 1998) and the difference of designing between the physical environment and virtual environment (Maher et al. 2000), we intend to study the possibilities of using digital models, in addition to drawings, as a critical media in the conceptual stage of building construction process in the near future (just as the critical role that physical models played in early design process in the Renaissance). This research is combined with two practical building projects, following the progress of construction by using digital models and animations to simulate the structural layouts of the projects. We also tried to solve the complicated and even conflicting problems in the detail and piping design process through an easily accessible and precise interface. An attempt was made to delineate the hierarchy of the elements in a single structural and constructional system, and the corresponding relations among the systems. Since building construction is often complicated and even conflicting, precision needed to complete the projects can not be based merely on 2D drawings with some imagination. The purpose of this paper is to describe all the related elements according to precision and correctness, to discuss every possibility of different thinking in design of electric-mechanical engineering, to receive feedback from the construction projects in the real world, and to compare the digital models with conventional drawings.Through the application of this research, the subtle relations between the conventional drawings and digital models can be used in the area of building construction. Moreover, a theoretical model and standard process is proposed by using conventional drawings, digital models and physical buildings. By introducing the intervention of digital media in design process of working drawings and shop drawings, there is an opportune chance to use the digital media as a prominent design tool. This study extends the use of digital model and animation from design process to construction process. However, the entire construction process involves various details and exceptions, which are not discussed in this paper. These limitations should be explored in future studies.

summary The last thirty years have seen the development of powerful new tools for architects and planners: CAD, 3D modeling, digital imaging, geographic information systems, and real time animated walkthroughs. That’s just the beginning. Based on our experience with CAD tools, analysis of design practice, and an understanding of computer hardware and software, we’re out to invent the next generation of tools. We think architects should be shakers and makers, not just consumers, of computer aided design. We started the Sundance Lab (for Computing in Design and Planning) in 1993 with a few people and machines. We’ve grown to more than a dozen people (mostly undergraduate students) and a diverse interdisciplinary array of projects. We’ve worked with architects and planners, anthropologists, civil engineers, geographers, computer scientists, and electrical engineers. Our work is about the built environment: its physical form and various information involved in making and inhabiting places. We cover a wide range of topics – from design information management to virtual space, from sketch recognition to design rationale capture, to communication between designer and computer. All start from the position that design is a knowledge based and information rich activity. Explicit representations of design information (knowledge, rationale, and rules) enables us to engage in more intelligent dialogues about design. The following describes some of our projects under various rubrics.

summary Information Technology, IT, has already submerged all human activities. The last three decades architectural design has been in the continuous whirlpool of technological innovation. Philosophers and researchers have wrote about the influence of IT on our everyday space perception. Architectural space, mainly changed on a social, technical, and phenomenological levels. It is great time to take a halt, and have an architect's look on how far all these information megabytes, megahertz, giga systems, world web, etc. have influenced architectural design and space production.

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 Modeling the Digital Earth in VRML
source Technical Note no. 559, SRI International, Menlo Park
summary This paper describes the representation and navigation of large, multi-resolution, georeferenced datasets in VRML97. This requires resolving nontrivial issues such as how to represent deep level of detail hierarchies efficiently in VRML; how to model terrain using geographic coordinate systems instead of only VRML's Cartesian representation; how to model georeferenced coordinates to sub-meter accuracy with only single-precision floating point support; how to enable the integration of multiple terrain datasets for a region, as well as cultural features such as buildings and roads; how to navigate efficiently around a large, global terrain dataset; and finally, how to encode metadata describing the terrain. We present solutions to all of these problems. Consequently, we are able to visualize geographic data in the order of terabytes or more, from the globe down to millimeter resolution, and in real-time, using standard VRML97.

doi https://doi.org/10.52842/conf.acadia.1998.316
summary We propose a prototype “kernel” of an object-oriented language, SOML (Scene Objects Modeling Language), intended to assist in the declarative design of scenes in image synthesis. This language is an attempt to provide the designer with a tool to facilitate the rapid prototyping of 3D scenes. It can also serve as a tool for knowledge acquisition and representation , and for communication and exchange of data with other tools in a design environment. Advantages offered by the implementation of SOML are: (a) from user’s viewpoint: the possibility of declarative description of the initial concept associated with the target scene in terms of properties and constraint vocabulary, the possibility of quantitative and qualitative reasoning on these properties, the modification of the intermediate solutions to different levels of detail, the utilisation of previous solutions; and (b) from the implementation viewpoint: the structuring of the properties and methods in the form of domain knowledge, the optimal solution generation according to heuristic causal-probabilistic criteria, the transformation of the semantic concept description of the scene in generic entry code for a geometrical CSG modeler or for rendering and visualization software, the integration of functionality for parameter generation and modification, the compilation of a scene from components of other final scenes and operations of geometrical transformations acting on groups of scenes. We present the architecture of the object-based implantation of the language and its interpreter, in the unified notation formalism UML. The utilization of the SOML language is illustrated by some examples.

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 Computer animation for architectural visualisation
source University of Strathclyde
summary This thesis critically reviews the state of architectural animation, and relates this specific field to the more general motion-based representations, particularly traditional film-making techniques. It identifies key elements from traditional filmmaking and shows how these elements can improve computer-based architectural animation. The process of identification of the key elements from traditional film-making starts with a critical survey of the use of motion-based representation in local architectural practices and an empirical analysis of several architectural-based documentary films and past and present computer animations. All of the key ideas are illustrated on video by comparing real shooting clips to digital sequences focusing on production and post-production works. Some of these were implemented in two live projects ( Ministry of Finance, Malaysia and Damansara Parade ) for architects to understand the real problems and potentials in each process. These sets of illustrations expand the architect ideas to make full use of the motion-based process to improve the skill of combining architectural information in a good animation. The overall production process becomes more efficient when the motion-based footage is edited using a non-linear editing platform as it enhances the professional appearance as well as vastly saving most of the production time. The thesis concludes with specific recommendations relative to the stage at which the animation is produced. This technology can be best utilised with the right skills (a gained from film-making) and an understanding of each stage that requires a different level of input and gives a certain impact to the viewers.

title From Real to Cyber Reality
source Cyber-Real Design [Conference Proceedings / ISBN 83-905377-2-9] Bialystock (Poland), 23-25 April 1998, pp. 11-19
summary Human activity takes place in two planes, at two levels. Practical activity is present in one of the planes, the other level is occupied by purely cognitive activity. When observing sufficiently long sequences of practical and cognitive activities, one notices transitions between them, which prove true the suspicions of their functional relationship. Because on both of these planes of human activity there is always one and the same element present - an informative element - which on the first plane functions as subordinate, and in the other as an independent one, one can search for a common characteristic for both planes. Such common characteristic for both levels of human activity can be perceived in the fact that in both situations the activity of a human is based on CREATION. Human thinking is based on transitions between what is accessible through experience and what is referred to conceptually. The human thought exists only and exclusively in the vertical motion: from the phenomenal level to the structural level direction of abstraction) and from the conceptual level to the empirical level direction of concretisation). All human activity is multilayered or, more precisely, it is an activity within many layers: the sensual one as well as the structural one. The appearance of conceptual thinking has created a qualitatively new type of a situation. This novelty can be easily seen both in the sphere of the practical cognitive activity as well as in the sphere of the pure cognitive activity. In both cases, the cognitive activity of a human is of a "double-decker" character: image and concept. It is necessary to note here that the "image" does not only mean structural, concrete, but also one which is purely visual, abstract, of no physical form. Therefore, the human experience, being the result of the cognitive activity, is being expressed, becoming objective, materialising in two different but compatible ways. Firstly, in the material structures of practical significance - this way the material culture is created. Secondly - in material structures which have no practical meaning but are solely used for expressing the spiritual contents - thus creating the spiritual culture. Humans have developed an extraordinarily strong need for spiritual activity, which is manifested by the material activity, redundant from the point of view of the material needs.

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.

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.

summary Development of net-based tools initiate a new architecture-computer science junction, offering a possibility to investigate distant exchange and updating of research work on architectural artefacts. Tools such as CAD platforms, rendering software and DBMS are integrated to the every day work of more and more architects and conservationists. Computer tools, which have been introduced in the process of analysing architecture as drawing and data management platforms, now bring to the fore a deeper change: distant analysis. The development of web technologies and the object oriented approach to knowledge representation give us an opportunity of research in the fields of collaborative work on architectural data models. The research presented in this paper focuses on a first set of network operative tools for a co-operation program aimed at developing web-enabled architectural data models referring to the evolution of Cracow's Old Town Hall.

title Generative music composition in practice - a critical evaluation
source International Conference on Generative Art
summary This critical evaluation will discuss 4 computer based musical works which, for reasons I shall explain, I describe as non-linear or generative. The works have been constructed by me and publicly performed or exhibited during a two year period from October 1998 to October 2000. ‘In the beginning…’ interactive music installation, strangeAttraction, Morley Gallery, London. July 1999 ‘jnrtv’ live generative dance music May 1999 to Dec 2000 ‘jazz’ interactive music installation, another strangeAttraction Morley Gallery, London. July 2000-09-26 ‘the street’ architectural interactive music installation, University of Westminster Oct 2000 Introduction I have always loved the practice of composing, particularly when it means scoring a work to be played by a live ensemble. There is something about taking a fresh sheet of manuscript , ruling the bar lines, adding clefs, key and time signatures and beginning the gradual process of adding notes, one at a time to the score until it is complete that is gratifying and compensates for the enormous effort involved. The process of scoring however is actually one distinct act within the more general task of creating music. Recently, the notion of ‘composing’ has met challenges through an increased interest in non-linear compositional methods. It is actually the presence of Chaotic or uncontrolable elements which add real beauty to music and many if not all of the things we value. If we think of a sunset, waves lapping on the shore, plants, trees a human face and the sound of the human voice, these things are not perfect and more importantly perhaps, they are transient, constantly changing and evolving. Last year and again this year, I have organised an exhibition of interactive , non-linear music installations called 'strangeAttraction'. The title refers to what Edward Lorenz called a ‘strange attractor’ the phenomenon that despite vast degrees of Chaos and uncertainty within a system, there is a degree of predictability, the tendency for chaotic behaviour to ‘attract’ towards a probable set of outcomes. Composition that deals with 'attractors' or probable outcomes rather than specific details which are set in stone is an increasingly intriguing notion.

title Displacement feature modelling for conceptual design
source Computer-Aided Design, Vol. 30 (1) (1998) pp. 19-27
summary Although the support of surface features, where a surface feature represents a local geometric detail imposed on a surface, is well-defined on prismatic objects, this is notthe case for sculptured surface models. Current methods often lead to data-explosion, high polynomial results, or procedural solutions. In this paper a method isdescribed that allows explicit modelling of protrusions and depressions in free-form B-spline surfaces. As this functionality is intended to be used by industrial designersduring conceptual design, distinct requirements are formulated to allow its use in this early stage of design. A method is described that calculates a blending geometryapproximating G1 cross-boundary smoothness effectively. Using these requirements and approximations, protrusions and depressions can be modelled with real-timeresponse, and with unprecedented flexibility.

summary Computer catalogues, files, digital maps and data bases are more and more widely used in planning studies not only in the world, but in Poland as well. They successfully replace manual and time- consuming elaboration of cartographic materials or uphill collecting of data, among others. The developing computerisation in architectural offices, physical planning or other area management centers will assure a studies results' transfer in the form of digital maps or computer data bases in the near future Computer technology forces changes of work technics and generates in the next step the demand for mathematical models used for examining of eco-social-economic systems functioning. The speed of data processing influences on the profitability of common usage of the source data available on magnetic recording media. Thus data processing and data aggregation according to the designers' needs are more simply and generating of new information essential for creating of updated constructive solutions is possible too. Sharply increasing information resources (like Internet) require the adoption of such techniques and models, which make easier to control still increasing number of over-complicated- structure data bases.

title Data Visualization Methods for the Blind using Force Feedback and Sonification
source Stein, M. (Ed.). Telemanipulator and Telepresence Technologies V. Vol. 3524
summary Research in the field of scientific visualization has begun to articulate systematic methods for mapping data to a perceivable form. Most work in this area has focused on the visual sense. For blind people in particular, systematic visualization methods which utilize other sense need further development. In this work we develop methods for adding aural feedback to an existing haptic force feedback interface to create a multimodal visualization system. We examine some fundamental components of a visualization system which include the following: characterization of the data, definition of user directives and interpretation aims, cataloging of sensual representations of information, and finally, matching the data and user interpretation aims with the appropriate sensual representations. We focus on the last two components as they relate to the aural and haptic sensor. Cataloging of sensual representations is drawn form current research in sonification and haptics. The matching procedure can be thought of as a type of encoding which should be the inverse of the decoding mechanism of our aural and haptic systems. Topics in human perception are discussed, and issues related to the interaction between the two sensor are addressed. We have implemented a visualization system in the from of a Windows NT application using a sound card and a 3 DOF point interaction haptic interface. The system present a 2D data set primarily as a polygonal haptic surface although other capabilities of the haptic sensor are utilized such as texture discernment. In addition, real time aural feedback is presented as the user explores the surface. Parameters of sound such as pitch and spectral content are used to convey information. Evaluation of the system's effectiveness as an assistive technology for the blind reveals that combining aural and haptic feedback improves visualization over using either of the two senses alone.
