summary In this paper we present an approach to the qualitative representation of shape and its use. We use a qualitative coding scheme founded on landmarks in the shape. The scheme encodes a qualitative representation of angles, relative side lengths and curvatures at landmarks. We then show how such a representation can be used as a basis for reasoning about shapes using extracted shape features. We conclude with a preliminary analysis of 12 sketches of the architect Louis Kahn and show how they may be categorised based on these shape features.

title Feature-Based Qualitative Modeling of Objects
source Proceedings of the Eighth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-8536-5] Atlanta, 7-8 June 1999, pp. 309-320
summary Objects represent fundamentally important ways with which to perceive and reason about the world. There are very few adequate representations for use at the early stages of designing. Feature- based approaches founded on qualitative representations have been used. This paper extends the qualitative representation developed for two-dimensional shapes to three-dimensional objects. It uses the qualitative representation to detect features. An example of the application of this representation is presented.

summary Computer applications in design have pursued two main development directions: analytical modelling and information technology. The former line has produced a large number of tools for reality simulation (i.e. finite element models), the latter is producing an equally large amount of advances in conceptual design support (i.e. artificial intelligence tools). Nevertheless we can trace rare interactions between computation models related to those different approaches. This lack of integration is the main reason of the difficulty of CAAD application to the preliminary stage of design, where logical and quantitative reasoning are closely related in a process that we often call 'qualitative evaluation'. This paper briefly surveys the current development of qualitative physical models applied in design and propose a general approach for modelling physical behaviour by means of Bayesian network we are employing to develop a tutoring and coaching system for natural ventilation preliminary design of halls, called VENTPad. This tool explores the possibility of modelling the causal mechanism that operate in real systems in order to allow a number of integrated logical and quantitative inference about the fluid-dynamic behaviour of an hall. This application could be an interesting connection tool between logical and analytical procedures in preliminary design aiding, able to help students or unskilled architects, both to guide them through the analysis process of numerical data (i.e. obtained with sophisticate Computational Fluid Dynamics software) or experimental data (i.e. obtained with laboratory test models) and to suggest improvements to the design.

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".

summary A series of experiments that investigate and demonstrate the visual logic of three-dimensional representation in animated form through the use of computers is presented. Perspective systems are designed to construct pictures that, when viewed, produce in the culturally trained viewer the experience of depicted objects that match perceivable objects. Panofsky wrote about how our capacities to see are constrained by the perspective system that we use, that is, by our way of depicting what we see. The kind of pictorial spaces are expressed through geometrical models. Each model is expressed as a geometrical transformation applied to Euclidean/Cartesian shapes of the physical environment. These transformations show how shapes are projected in pictorial space.

title Modelling architectural design information by features : an approach to dynamic product modelling for application in architectural design
source Eindhoven University of Technology
summary Architectural design, like many other human activities, benefits more and more from the ongoing development of information and communication technologies. The traditional paper documents for the representation and communication of design are now replaced by digital media. CAD systems have replaced the drawing board and knowledge systems are used to integrate expert knowledge in the design process. Product modelling is one of the most promising approaches in the developments of the last two decades, aiming in the architectural context at the representation and communication of the information related to a building in all its aspects and during its complete life-cycle. However, after studying both the characteristics of the product modelling approach and the characteristics of architectural design, it is concluded in this research project that product modelling does not suffice for support of architectural design. Architectural design is characterised mainly as a problem solving process, involving illdefined problems that require a very dynamic way of dealing with information that concerns both the problem and emerging solutions. Furthermore, architectural design is in many ways an evolutionary process. In short term this is because of the incremental approach to problem solving in design projects; and in long term because of the stylistic development of designers and the continuous developments in the building and construction industry in general. The requirements that are posed by architectural design are concentrated in the keywords extensibility and flexibility of the design informationmodels. Extensibility means that designers can extend conceptual models with definitions that best suit the design concepts they wish to utilise. Flexibility means that information in design models can be structured in a way that accurately represents the design rationale. This includes the modelling of incidental characteristics and relationships of the entities in the model that are not necessarily predefined in a conceptual model. In general, product modelling does not adequately support this dynamic nature of design. Therefore, this research project has studied the concepts developed in the technology of Feature-based modelling, which originates from the area of mechanical engineering. These concepts include the usage of Features as the primitives for defining and reasoning about a product. Features have an autonomous function in the information model, which, as a result, constitutes a flexible network of relationships between Features that are established during the design process. The definition of Features can be specified by designers to formalise new design concepts. This allows the design tools to be adapted to the specific needs of the individual designer, enlarging the library of available resources for design. In addition to these key-concepts in Feature-based modelling as it is developed in the mechanical engineering context, the project has determined the following principles for a Feature-based approach in the architectural context. Features in mechanical engineering are used mainly to describe the lowest level of detail in a product's design, namely the characteristics of its parts. In architecture the design process does not normally follow a strictly hierarchical approach and therefore requires that the building be modelled as a whole. This implies that multiple levels of abstraction are modelled and that Features are used to describe information at the various abstraction levels. Furthermore, architectural design involves concepts that are non-physical as well as physical; Features are to be used for modelling both kinds. The term Feature is defined in this research project to reflect the above key-concepts for this modelling approach. A Feature is an autonomous, coherent collection of information, with semantic meaning to a designer and possibly emerging during design, that is defined to formalise a design concept at any level of abstraction, either physical or non-physical, as part of a building model. Feature models are built up entirely of Features and are structured in the form of a directed graph. The nodes in the graph are the Features, whereas the arcs are the relationships between the Features. Features can be of user-defined types and incidental relationships can be added that are not defined at the typological level. An inventory in this project of what kind of information is involved in the practice of modelling architectural design is based on the analysis of a selection of sources of architectural design information. This inventory is deepened by a case study and results in the proposition of a categorisation of architectural Feature types.

summary Applications of information technology (IT) in the architectural profession have greatly increased in the past decades, ranging nowadays from concept design to automated construction. There are countless applications in the architecture practice that go well beyond representation, such as BIM software, generative design systems, and rapid prototyping and fabrication. For this reason, IT has been a frequent graduate research topic. In the present research academic graduate theses that dealt with IT in architecture since 1999 were surveyed and categorized, with the purpose of comparing the topics, applications and methods that are studied in Brazil and abroad. We hope that the differences found will help Brazilian architecture schools to update their IT curriculum, overcoming old prejudices against the use of computers in the creative phases of design.

title Digitally Mediated Design: Using Computer Programming to Develop a Personal Design Process
source Massachusetts Institute of Technology, Department of Architecture
summary This thesis is based on the proposal that the current system of architectural design education confuses product and process. Students are assessed through, and therefore concentrate on, the former whilst the latter is left in many cases to chance. This thesis describes a new course taught by the author at MIT for the last three years whose aim is to teach the design process away from the complexities inherent in the studio system. This course draws a parallel between the design process and the Constructionist view of learning, and asserts that the design process is a constant learning activity. Therefore, learning about the design process necessarily involves learning the cognitive skills of this theoretical approach to education. These include concrete thinking and the creation of external artifacts to develop of ideas through iterative, experimental, incremental exploration. The course mimics the Constructionist model of using the computer programming environment LOGO to teach mathematics. It uses computer programming in a CAD environment, and specifically the development of a generative system, to teach the design process. The efficacy of such an approach to architectural design education has been studied using methodologies from educational research. The research design used an emergent qualitative model, employing Maykut and Morehouses interpretive descriptive approach (Maykut & Morehouse, 1994) and Glaser and Strausss Constant Comparative Method of data analysis (Glaser & Strauss, 1967). Six students joined the course in the Spring 1999 semester. The experience of these students, what and how they learned, and whether this understanding was transferred to other areas of their educational process, were studied. The findings demonstrated that computer programming in a particular pedagogical framework, can help transform the way in which students understand the process of designing. The following changes were observed in the students during the course of the year: Development of understanding of a personalized design process; move from using computer programming to solve quantifiable problems to using it to support qualitative design decisions; change in understanding of the paradigm for computers in the design process; awareness of the importance of intrapersonal and interpersonal communication skills; change in expectations of, their sense of control over, and appropriation of, the computer in the design process; evidence of transference of cognitive skills; change from a Behaviourist to a Constructionist model of learning Thesis Supervisor: William J.

title Let's Improvise Together
source International Conference on Generative Art
summary The creators of ‘Let's-Improvise-Together’ adhere to the idea that while there is a multitude of online games now available in cyberspace, it appears that relatively few are focused on providing a positive, friendly and productive experience for the user. Producing this kind of experience is one the goals of our Amusement Project.To this end, the creation of ‘Let's Improvise Together’ has been guided by dedication to the importance of three themes:* the importance of cooperation,* the importance of creativity, and* the importance of emotion.Description of the GameThe avatar arrives in a certain area where there are many sound-blocks/objects. Or he may add sound "property" to existing ones. He can add new objects at will. Each object may represents a different sound, they do not have to though. The avatar walks around and chooses which objects he likes. Makes copies of these and add sounds or change the sounds on existing ones, then with all of the sound-blocks combined make his personalized "instrument". Now any player can make sounds on the instrument by approaching or bumping into a sound-block. The way that the avatar makes sounds on the instrument can vary. At the end of the improvising session, the ‘composition’ will be saved on the instrument site, along with the personalized instrument. In this way, each user of the Amusement Center will leave behind him a unique instrumental creation, that others who visit the Center later will be able to play on and listen to. The fully creative experience of making a new instrument can be obtained connecting to Active Worlds world ‘Amuse’ and ‘Amuse2’.Animated colorful sounding objects can be assembled by the user in the Virtual Environment as a sort of sounding instrument. We refrain here deliberately from using the word musical instrument, because the level of control we have on the sound in terms of rythm and melody, among other parameters, is very limited. It resembles instead, very closely, to the primitive instruments used by humans in some civilizations or to the experience made by children making sound out of ordinary objects. The dimension of cooperation is of paramount importance in the process of building and using the virtual sounding instrument. The instrument can be built on ones own effort but preferably by a team of cooperating users. The cooperation has as an important corolary: the sharing of the experience. The shared experience finds its permanence in the collective memory of the sounding instruments built. The sounding instrument can be seen also as a virtual sculpture, indeed this sculpture is a multimedial one. The objects have properties that ranges from video animation to sound to virtual physical properties like solidity. The role of the user representation in the Virtual World, called avatar, is important because it conveys, among other things, the user’s emotions. It is worth pointing out that the Avatar has no emotions on its own but it simply expresses the emotions of the user behind it. In a way it could be considered a sort of actor performing the script that the user gives it in real-time while playing.The other important element of the integration is related to the memory of the experience left by the user into the Virtual World. The new layout is explored and experienced. The layout is a permanent editable memory. The generative aspects of Let's improvise together are the following.The multi-media virtual sculpture left behind any participating avatar is not the creation of a single author/artist. The outcome of the sinergic interaction of various authors is not deterministic, nor predictable. The authors can indeed use generative algorythm in order to create the texture to be used on the objects. Usually, in our experience, the visitors of the Amuse worlds use shareware programs in order to generate their texture. In most cases the shareware programs are simple fractals generators. In principle, it is possible to generate also the shape of the object in a generative way. Taking into account the usual audience of our world, we expected visitors to use very simple algorythm that could generate shapes as .rwx files. Indeed, noone has attempted to do so insofar. As far as the music is concerned, the availability of shareware programs that allow simple generation of sounds sequences has made possible, for some users, to generate sounds sequences to be put in our world. In conclusion, the Let's improvise section of the Amuse worlds could be open for experimentation on generative art as a very simple entry point platform. We will be very happy to help anybody that for educational purposes would try to use our platform in order to create and exhibit generative forms of art.

title Infographic: Its Incorporation and Relativity in Architectural Design Process
source III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 313-318
summary This paper is about an architectural design workshop regularly held at a public university in Santa Fe, Argentina. The class is about 150 students large, with different informatic capabilities and hardware facilities. The design problem of the workshop, which is one year long, is the relationship between architectural project and the construction of the urbanity. This implies both a physical intervention and a cultural expression. Pedagogy seeks students to overcome individualism, characteristic that is hardly induced by PCs, making a socialized design experience. A complementary and simultaneous use of graphic and infographic data is one of the main criteria of the workshop. The idea is to look for students to reach a wide vision by means of the use of different representation systems and means of information. Digital graphic is introduced early in the design process as an electronic model of urban context. It is considered as a one among many other graphic resources and is used together with ordinary models, geometric drawings, aerial and regular photography and hand made sketches. This paper relates the results that have been obtained when students were asked to make an analytic and sensitive approach to the relationship site - urban situation. This relationship has a great importance for the workshop since its goal is to make students to understand the the value of designing in and for the city.

summary Throughout known architectural history, representation, media and design have been recognized to have a close relationship. This relationship is inseparable; representation being a means for engaging in design thinking and making and this activity requiring media. Interpretations as to what exactly this relationship is or means have been subject to debate, disagreement and change along the ages. Whereas much has been said about the interactions between representation and design, little has been elaborated on the relationship between media and design. Perhaps, it is not until now, surrounded by all kinds of media at the turn of the millennium, as Johnson argues (1997), that we have enough context to be able to see and address the relationship between media and human activities with some degree of perspective.

summary Art historians and critics have defined the style as common features appeared in a class of objects. Abstract common features from a set of objects have been used as a bench mark for date and location of original works. Common features in shapes are identified by relationships as well as physical properties from shape descriptions. This paper will focus on how the computer recognises common shape properties from a class of shape objects to learn style. Shape representation using schema theory has been explored and possible inductive generalisation from shape descriptions has been investigated.

title Virtual components consisting of form, function and behavior
source Automation in Construction 8 (3) (1999) pp. 351-367
summary Software can produce a product model of a building as a consequence of the designers' actions in drawing and evaluating the design. The actions of the designer include interpreting, predicting and assessing the emerging design and describe the building in terms of forms, functions and behaviors. A software prototype has been implemented that incorporates this understanding of the design process in the field of building design. It employs object-oriented classes to represent forms, functions and behaviors. As a software user draws and interprets the design for multiple evaluation issues, the software creates a unique `virtual component' for each entity. During automated reasoning to evaluate the emerging design, virtual components collect and organize form, function and behavior instances to describe the parts of the building. In comparison to other product models, our approach, which we refer to as a `Virtual Product Model', better accommodates change, provides increased support for the design process and enriches the product representation by including function and behavior.

summary It is undeniable that infotechnology has brought significant changes into architectural representation. Whether these changes has altered design conception proccess or are only media matters, is a discussion concerned with the role of graphic expression in architects designs. Is it just a language, or a design thinking tool, fully engaged with the formal solution? Thus, the investigation of the role of represententional systems in the design thinking proccess and the analysis of their intrinsic relationship will approach traditional methods facing the widespread use of Computer Aided Design. There are polemics about the issue: on the one hand, seductive simulations and a plethora of rendering choices available, on the other hand, impersonal expression, to name a few arguments for and against CAD use. Computers have not replaced the straight reciprocity between the acts of conceiving and drawing, between mind and image, which results in manual sketches, quite effective in embodying a design idea. Yet, we have to admit that manipulating complex forms such as Gehry's Guggenheim Museum quickly would not be feasible before CAD advent. We have been faced with new paradigms challenging the graphic expression of architects and urban designers. Besides the consequences of this new reality to design thinking, a crucial point to be stressed at this discussion is the possibility of achieving a balance between the cherished mind-hand intimacy and the available technological resources.

title The Front of the Stage of Vitruvius' Roman Theatre - A new Approach of Computer Aided Design that Transforms Geometric Operators to Semantic Operators
source Proceedings of the Eighth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-8536-5] Atlanta, 7-8 June 1999, pp. 321-333
summary The driving force of all researches where the systems of computation are used, is the utilization of an intelligent method for the representation of building. The use of computer, in design process, is often limited to technical functions (tekhne), and what one usually calls computer-aided design is often no more than computer-aided drawing. In this research paper we continue a reflection on the architect's work methods, and suggest an approach to design based on the semantic properties of the object (i.e. semantic operators), rather than by geometric operators. We propose a method of computer aid design using procedural models where the initial state of design is vague and undefined. We operate from a paradigm that leads to represent a building by means of parametric functions that, expressed algorithmically, give a procedural model to facilitate the design process. This approach opens new avenues that would permit to add the logos (semantic properties) and lead to a metaphorical representation. By means of procedural models, we show that, from a generic model we can produce a four dimensional model that encapsulate a volumetric model with semantic characteristics. We use a meta-functional language that allows us to model the actions and encapsulate detailed information about various building elements. This descriptive mechanism is extremely powerful. It helps to establish relations between the functions, contributes to a better understanding of the project's aim, and encapsulates the building properties by recalling characteristics of common classes which give rise to a new configuration and a completely original design. The scientific result of this experiment is the understanding and confirmation of the hypothesis that it is possible to encapsulate, by means of computing process, the links between design moves during conceptual and figural decisions and transform the geometric operators in semantic operators.

title Coding and Modelling Communication in Architectural Collaborative Design
doi https://doi.org/10.52842/conf.acadia.1999.152
source Media and Design Process [ACADIA ‘99 / ISBN 1-880250-08-X] Salt Lake City 29-31 October 1999, pp. 152-166
summary Although there has been some research done on collaborative face-to-face (FTF) and video-conferencing sessions involving architects, little is know about the effects these different mediums have on collaborative design in general and collaborative communication and design representation in particular. In this paper we argue that successful computer-mediated collaborative design (CMCD) does not necessarily mean emulating close proximity environments. In order to investigate this view, we carried out experiments examining the effect and significance of different communication channels in collaborative sessions between architects. The experiments were conducted in different environments and classified into three categories. The first category is FTF. The second computer mediated collaborative design sessions with full communication channels CMCD-a. The third category was conducted also through computer mediated collaborative design sessions but with limited communication channels CMCD-b. A custom coding scheme is developed using data, external and theoretically derived coding categories as a base. Examples of how the proposed coding scheme works are given from all three categories of experiments. The coding scheme provides the basis for modeling and understanding communication in collaborative design.

title A comprehensive computational environment for performance based reasoning in building design and evaluation
source Automation in Construction 8 (4) (1999) pp. 427-435
summary This paper introduces a comprehensive computational implementation effort toward the incorporation of simulation-based performance evaluation in building design. Specifically, the computational design support system `SEMPER' will be described. SEMPER's main objectives are: (i) a methodologically consistent (first-principles-based) and flexible performance modeling approach through the entire building design and engineering process; (ii) provision of comprehensive, i.e., multi-domain building performance evaluation support; (iii) seamless and dynamic communication between the simulation model and the general building representation in an object-oriented space-based design environment; and (iv) active convergence support via a bi-directional inference mechanism that provides not only the conventional design-to-performance mapping option but also a `preference-based' performance-to-design mapping technology.
