summary It is all too common for technology companies to seek a new route to solving the same problem but for the most part the solutions address the effect and not the cause. The good old-fashioned pencil is the perfect example where inventors have sought to design-out the effect of the inherent brittleness of lead. Traditionally different methods of sharpening were suggested and more recently the propelling pencil has reigned king, the lead being supported by the dispensing sleeve thus reducing the likelihood of breakage. Developers convinced by the Single Building Model approach to design development have each embarked on a difficult journey to create an easy to use feature packed application. Unfortunately it seems that the two are not mutually compatible if we are to believe what we see emanating from Technology giants Autodesk in the guise of Architectural Desktop 3. The effect of their development is a feature rich environment but the cost and in this case the cause is a tool which is far from easy to use. However, this is only a small part of a much bigger problem, Interoperability. You see when one designer develops a model with one tool the information is typically locked in that environment. Of course the geometry can be distributed and shared amongst the team for use with their tools but the properties, or as often misquoted, the intelligence is lost along the way. The effect is the technological version of rubble; the cause is the low quality of data-translation available to us. Fortunately there is one company, which is making rapid advancements on the whole issue of collaboration, and data sharing. An old timer (Graphisoft - famous for ArchiCAD) has just donned a smart new suit, set up a new company called GDL Technology and stepped into the ring to do battle, with a difference. The difference is that GDL Technology does not rely on conquering the competition, quite the opposite in fact their success relies upon the continued success of all the major CAD platforms including AutoCAD, MicroStation and ArchiCAD (of course). GDL Technology have created a standard data format for manufacturers called GDL Objects. Product manufacturers such as Velux are now able to develop product libraries using GDL Objects, which can then be placed in a CAD model, or drawing using almost any CAD tool. The product libraries can be stored on the web or on CD giving easy download access to any building industry professional. These objects are created using scripts which makes them tiny for downloading from the web. Each object contains 3 important types of information: · Parametric scale dependant 2d plan symbols · Full 3d geometric data · Manufacturers information such as material, colour and price Whilst manufacturers are racing to GDL Technologies door to sign up, developers and clients are quick to see the benefit too. Porsche are using GDL Objects to manage their brand identity as they build over 300 new showrooms worldwide. Having defined the building style and interior Porsche, in conjunction with the product suppliers, have produced a CD-ROM with all of the selected building components such as cladding, doors, furniture, and finishes. Designing and detailing the various schemes will therefore be as straightforward as using Lego. To ease the process of accessing, sizing and placing the product libraries GDL Technology have developed a product called GDL Object Explorer, a free-standing application which can be placed on the CD with the product libraries. Furthermore, whilst the Object Explorer gives access to the GDL Objects it also enables the user to save the object in one of many file formats including DWG, DGN, DXF, 3DS and even the IAI's IFC. However, if you are an AutoCAD user there is another tool, which has been designed especially for you, it is called the Object Adapter and it works inside of AutoCAD 14 and 2000. The Object Adapter will dynamically convert all GDL Objects to AutoCAD Blocks during placement, which means that they can be controlled with standard AutoCAD commands. Furthermore, each object can be linked to an online document from the manufacturer web site, which is ideal for more extensive product information. Other tools, which have been developed to make the most of the objects, are the Web Plug-in and SalesCAD. The Plug-in enables objects to be dynamically modified and displayed on web pages and Sales CAD is an easy to learn and use design tool for sales teams to explore, develop and cost designs on a Notebook PC whilst sitting in the architects office. All sales quotations are directly extracted from the model and presented in HTML format as a mixture of product images, product descriptions and tables identifying quantities and costs. With full lifecycle information stored in each GDL Object it is no surprise that GDL Technology see their objects as the future for building design. Indeed they are not alone, the IAI have already said that they are going to explore the possibility of associating GDL Objects with their own data sharing format the IFC. So down to the dirty stuff, money and how much it costs? Well, at the risk of sounding like a market trader in Petticoat Lane, "To you guv? Nuffin". That's right as a user of this technology it will cost you nothing! Not a penny, it is gratis, free. The product manufacturer pays for the license to host their libraries on the web or on CD and even then their costs are small costing from as little as 50p for each CD filled with objects. GDL Technology has come up trumps with their GDL Objects. They have developed a new way to solve old problems. If CAD were a pencil then GDL Objects would be ballistic lead, which would never break or loose its point. A much better alternative to the strategy used by many of their competitors who seek to avoid breaking the pencil by persuading the artist not to press down so hard. If you are still reading and you have not already dropped the magazine and run off to find out if your favorite product supplier has already signed up then I suggest you check out the following web sites www.gdlcentral.com and www.gdltechnology.com. If you do not see them there, pick up the phone and ask them why.

title Perception Aspects in Underground Spaces using Intelligent Knowledge Modeling
source Delft University of Technology
summary The intensification, combination and transformation are main strategies for future spatial development of the Netherlands, which are stated in the Fifth Bill regarding Spatial Planning. These strategies indicate that in the future, space should be utilized in a more compact and more efficient way requiring, at the same time, re-evaluation of the existing built environment and finding ways to improve it. In this context, the concept of multiple space usage is accentuated, which would focus on intensive 4-dimensional spatial exploration. The underground space is acknowledged as an important part of multiple space usage. In the document 'Spatial Exploration 2000', the underground space is recognized by policy makers as an important new 'frontier' that could provide significant contribution to future spatial requirements.In a relatively short period, the underground space became an important research area. Although among specialists there is appreciation of what underground space could provide for densely populated urban areas, there are still reserved feelings by the public, which mostly relate to the poor quality of these spaces. Many realized underground projects, namely subways, resulted in poor user satisfaction. Today, there is still a significant knowledge gap related to perception of underground space. There is also a lack of detailed documentation on actual applications of the theories, followed by research results and applied techniques. This is the case in different areas of architectural design, but for underground spaces perhaps most evident due to their infancv role in general architectural practice. In order to create better designs, diverse aspects, which are very often of qualitative nature, should be considered in perspective with the final goal to improve quality and image of underground space. In the architectural design process, one has to establish certain relations among design information in advance, to make design backed by sound rationale. The main difficulty at this point is that such relationships may not be determined due to various reasons. One example may be the vagueness of the architectural design data due to linguistic qualities in them. Another, may be vaguely defined design qualities. In this work, the problem was not only the initial fuzziness of the information but also the desired relevancy determination among all pieces of information given. Presently, to determine the existence of such relevancy is more or less a matter of architectural subjective judgement rather than systematic, non-subjective decision-making based on an existing design. This implies that the invocation of certain tools dealing with fuzzy information is essential for enhanced design decisions. Efficient methods and tools to deal with qualitative, soft data are scarce, especially in the architectural domain. Traditionally well established methods, such as statistical analysis, have been used mainly for data analysis focused on similar types to the present research. These methods mainly fall into a category of pattern recognition. Statistical regression methods are the most common approaches towards this goal. One essential drawback of this method is the inability of dealing efficiently with non-linear data. With statistical analysis, the linear relationships are established by regression analysis where dealing with non-linearity is mostly evaded. Concerning the presence of multi-dimensional data sets, it is evident that the assumption of linear relationships among all pieces of information would be a gross approximation, which one has no basis to assume. A starting point in this research was that there maybe both linearity and non-linearity present in the data and therefore the appropriate methods should be used in order to deal with that non-linearity. Therefore, some other commensurate methods were adopted for knowledge modeling. In that respect, soft computing techniques proved to match the quality of the multi-dimensional data-set subject to analysis, which is deemed to be 'soft'. There is yet another reason why soft-computing techniques were applied, which is related to the automation of knowledge modeling. In this respect, traditional models such as Decision Support Systems and Expert Systems have drawbacks. One important drawback is that the development of these systems is a time-consuming process. The programming part, in which various deliberations are required to form a consistent if-then rule knowledge based system, is also a time-consuming activity. For these reasons, the methods and tools from other disciplines, which also deal with soft data, should be integrated into architectural design. With fuzzy logic, the imprecision of data can be dealt with in a similar way to how humans do it. Artificial neural networks are deemed to some extent to model the human brain, and simulate its functions in the form of parallel information processing. They are considered important components of Artificial Intelligence (Al). With neural networks, it is possible to learn from examples, or more precisely to learn from input-output data samples. The combination of the neural and fuzzy approach proved to be a powerful combination for dealing with qualitative data. The problem of automated knowledge modeling is efficiently solved by employment of machine learning techniques. Here, the expertise of prof. dr. Ozer Ciftcioglu in the field of soft computing was crucial for tool development. By combining knowledge from two different disciplines a unique tool could be developed that would enable intelligent modeling of soft data needed for support of the building design process. In this respect, this research is a starting point in that direction. It is multidisciplinary and on the cutting edge between the field of Architecture and the field of Artificial Intelligence. From the architectural viewpoint, the perception of space is considered through relationship between a human being and a built environment. Techniques from the field of Artificial Intelligence are employed to model that relationship. Such an efficient combination of two disciplines makes it possible to extend our knowledge boundaries in the field of architecture and improve design quality. With additional techniques, meta know/edge, or in other words "knowledge about knowledge", can be created. Such techniques involve sensitivity analysis, which determines the amount of dependency of the output of a model (comfort and public safety) on the information fed into the model (input). Another technique is functional relationship modeling between aspects, which is derivation of dependency of a design parameter as a function of user's perceptions. With this technique, it is possible to determine functional relationships between dependent and independent variables. This thesis is a contribution to better understanding of users' perception of underground space, through the prism of public safety and comfort, which was achieved by means of intelligent knowledge modeling. In this respect, this thesis demonstrated an application of ICT (Information and Communication Technology) as a partner in the building design process by employing advanced modeling techniques. The method explained throughout this work is very generic and is possible to apply to not only different areas of architectural design, but also to other domains that involve qualitative data.

title Parametric design: a review and some experiences
source Automation in Construction 9 (4) (2000) pp. 369-377
summary During the last few years there has been an extraordinary development of computer-aided tools intended to present or communicate the results of architectural projects. But there has not been a comparable progress in the development of tools intended to assist design to generate architectural forms in an easy and interactive way. Even worse, architects who use the powerful means provided by computers as a direct tool to create architectural forms are still an exception. Architecture continues to be produced by traditional means using the computer as little more than a drafting tool. The main reasons that may explain this situation can be identified rather easily, although there will be significant differences of opinion. In my opinion, it is a mistake trying to advance too rapidly and, for instance, proposing integrated design methods using expert systems and artificial intelligence while no adequate tools to generate and modify simple 3D-models are available. The modeling tools we have at the present moment are unsatisfactory. Their principal limitation is the lack of appropriate instruments to modify interactively the model once it has been created. This is a fundamental aspect in any design activity, where the designer is constantly going forward and backwards, re-elaborating once and again some particular aspect of the model, or its general layout, or even coming back to a previous solution that had been temporarily abandoned. This paper presents a general summary of the actual situation and recent developments that may be incorporated to architectural design tools in a near future, together with some critical remarks about their relevance to architecture.

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 The paper is focused around a critical discussion of the digital representation and the architectural design process. Digital technology is now widely accepted and computers are causing a profound impact in the way reality and artificial objects are described and represented. Computers are now transforming skills, design processes, production processes and organizations. However, the evidence suggests that there are no fundamental changes in the architectural design process. It is acknowledged that the design process in architecture goes through representations and entails two altering phases: one generating tentative possibilities and hypothesis, and another of testing and evaluation. Based on this discussion a new way of using digital technology in architectural conception and design is suggested.

summary The core theme of this book is the idea of looking forward to where research and development in Computer Aided Architectural Design might be heading. The contention is that we can do so most effectively by using the developments that have taken place over the past three or four decades in Computing and Architectural Computing as our reference point; the past informing the future. The genesis of this theme is the fact that a new millennium is about to arrive. If we are ruthlessly objective the year 2000 holds no more significance than any other year; perhaps we should, instead, be preparing for the year 2048 (2k). In fact, whatever the justification, it is now timely to review where we stand in terms of the development of Architectural Computing. This book aims to do that. It is salutary to look back at what writers and researchers have said in the past about where they thought that the developments in computing were taking us. One of the common themes picked up in the sections of this book is the developments that have been spawned by the global linkup that the worldwide web offers us. In the past decade the scale and application of this new medium of communication has grown at a remarkable rate. There are few technological developments that have become so ubiquitous, so quickly. As a consequence there are particular sections in this book on Communication and the Virtual Design Studio which reflect the prominence of this new area, but examples of its application are scattered throughout the book. In 'Computer-Aided Architectural Design' (1977), Bill Mitchell did suggest that computer network accessibility from expensive centralised locations to affordable common, decentralised computing facilities would become more commonplace. But most pundits have been taken by surprise by just how powerful the explosive cocktail of networks, email and hypertext has proven to be. Each of the ingredients is interesting in its own right but together they have presented us with genuinely new ways of working. Perhaps, with foresight we can see what the next new explosive cocktail might be.

But we usually fell "astray" in there because there are no signs like roads, bridges, like it is in the physical world. This paper tries to cite the Lynch's (1960) urban design theory, then to develop a new Internet search mechanism's graphic user interface, and tries to help people explore in Internet more effectively.

summary An ever-increasing number of offices as also residential buildings are being realised by designers and investors in accordance with the concept of an intelligent building. Houses of the new generation are being constructed. This is possible thanks to dynamic progress in the development of computer and microprocessor engineering techniques. Putting into reality the idea of the 'intelligent building' will become one of the most interesting assignments of Polish building industry in the rapidly approaching XXI century. The term 'intelligent building' first appeared in the eighties. The idea behind this conception is aspiring to create a friendly, work supporting, effective environment. The revolution in telecommunications and information technology along with change in the standards of office work, have caused computer networks and modem systems of automation and protection, to invade buildings. From the technical point of view, an intelligent building is an object in which all the subsystems co-operate with each other, forming a friendly environment for man. For users of an intelligent building, the most important issue is realisation of the following aims: object management which includes both control of human resources and automation systems in the building and also efficient management of the building space in such a way that the costs of its utilisation are minimised. The possibility of optional installation of modern systems and equipment should be facilitated by the architecture itself. Therefore, the specifics of all the building elements should be taken into account right at the designing stage. The following features characterise an intelligent building: integration of telecommunication systems in the building, central management and supervision system and utilisation of structural cabling as the carrier of signals controlling most of the systems in the building. Presently, there is no building in Poland that could be characterised by the three features mentioned.

title GA2: a Programming Environment for Abstract Generative Fine Art
source International Conference on Generative Art
summary Fine artists looking to use computers to create generative works, especially those artists inclined towards abstraction, often face an uncomfortable choice in the selection of software tools. On the one hand there are a number of commercial and shareware programs available which implement a few techniques in an easy to use GUI environment. Unfortunately such programs often impose a certain look or style and are not terribly versatile or expressive. The other choice seems to be writing code from scratch, in a language such as c or Java. This can be very time consuming as every new work seems to demand a new program, and the artist's ability to write code can seldom keep pace with his ability to imagine new visual ideas. This paper describes a software system created by the author called GA2 which has been implemented in the Matlab software environment. By layering GA2 over Matlab the artist can take advantage of a very mature programming environment which includes extensive mathematical libraries, simple graphics routines, GUI construction tools, built-in help facilities, and command line, batch mode, and GUI modes of interaction. In addition, GA2 is very portable and can run on Macintosh, Windows, and Unix systems with almost no incremental effort for multi-platform support. GA2 is a work in progress and an extension of the completed GA1 environment. It is medium independent, and can be used for all manner of image, animation, and sound production. GA1 includes a complete set of genetic algorithm operations for breeding families of graphical marks, a database function for managing and recalling various genes, a set of statistical operations for creating various distributions of marks on a canvas or animation frame, a unique Markov-chain-likeoperator for generating families of visually similar lines or paths, and a complete L-system implementation. GA2 extends GA1 by adding more generative techniques such as tiling and symmetry operations, Thom's cusp catastrophe, and mechanisms inspired by complexity science notions such as cellular automata, fractals, artificial life, and chaos. All of these techniques are encapulated in genetic representations. This paper is supplemented with examples from the authors art work, and comments on the philosophy behind this method of working, and its relation towards the reinvigoration of abstraction after post-modernism.

title Creative computer aided architectural design An internal approach to the design process
source University of Oulu (Finland)
summary This survey can be seen as quite multidisciplinary research. The basis for this study has been inapplicability of different CAD user interfaces in architectural design. The objective of this research is to improve architectural design from the creative problem-solving viewpoint, where the main goal is to intensify architectural design by using information technology. The research is linked to theory of methods, where an internal approach to design process means studying the actions and thinking of architects in the design process. The research approach has been inspired by hermeneutics. The human thinking process is divided into subconscious and conscious thinking. The subconscious plays a crucial role in creative work. The opposite of creative work is systematic work, which attempts to find solutions by means of logical inference. Both creative and systematic problem solving have had periods of predominance in the history of Finnish architecture. The perceptions in the present study indicate that neither method alone can produce optimal results. Logic is one of the tools of creativity, since the analysis and implementation of creative solutions require logical thinking. The creative process cannot be controlled directly, but by creating favourable work conditions for creativity, it can be enhanced. Present user interfaces can make draughting and the creation of alternatives quicker and more effective in the final stages of designing. Only two thirds of the architects use computers in working design, even the CAD system is being acquired in greater number of offices. User interfaces are at present inflexible in sketching. Draughting and sketching are the basic methods of creative work for architects. When working with the mouse, keyboard and screen the natural communication channel is impaired, since there is only a weak connection between the hand and the line being drawn on the screen. There is no direct correspondence between hand movements and the lines that appear on the screen, and the important items cannot be emphasized by, for example, pressing the pencil more heavily than normally. In traditional sketching the pen is a natural extension of the hand, as sketching can sometimes be controlled entirely by the unconscious. Conscious efforts in using the computer shift the attention away from the actual design process. However, some architects have reached a sufficiently high level of skill in the use of computer applications in order to be able to use them effectively in designing without any harmful effect on the creative process. There are several possibilities in developing CAD systems aimed at architectural design, but the practical creative design process has developed during a long period of time, in which case changing it in a short period of time would be very difficult. Although CAD has had, and will have, some evolutionary influences on the design process of architects as an entity, the future CAD user interface should adopt its features from the architect's practical and creative design process, and not vice versa.

summary Leeds Metropolitan University is well placed to carry out research into multi-disciplinary team-working, as all the design and construction disciplines are housed in one faculty. Staff have set up an experimental project, TIME IT (Team-working in Multi-disciplinary Environments using IT) which examines ways of working in the design/construction process and how IT is used when there is no commercial pressure. Four groups of four students, one graduate diploma architect, and one final year student from each of Civil Engineering, Construction Management and Quantity Surveying have been working on feasibility studies for projects that are based on completed schemes or have been devised by collaborators in the Construction Industry. Students have been asked to produce a PowerPoint presentation, in up to five working days, of a design scheme, with costs, structural analysis and construction programme. The students are not assessed on the quality of the product, but on their own ability to monitor the process and use of IT. Despite this, aggressive competition evolved between the teams to produce the 'best' design. Five projects were run in the 1998/99 session. A dedicated IT suite has been provided; each group of students had exclusive use of a machine. They were not told how to approach the projects nor when to use the available technology, but were asked to keep the use of paper to a minimum and to keep all their work on the server, so that it could be monitored externally. Not so. They plotted the AO drawings of an existing building that had been provided on the server. They like paper - they can scribble on it, fold it, tear it and throw it at one another.

title SpaceScope: Developing a Spatial Information Retrieval System - Focused on Apartment Unit Floor Plans -
source Yonsei University, Dept. of Housing & Interior Design
summary This research investigates the spatial information retrieval (IR) in architecture focused on constructing efficient metadata that is crucial for data retrieval. Generally speaking, metadata is ‘structured data about data’ to describe resources especially in a digital format. In this research, metadata is a sort of data object to be useful in searching spatial information. Metadata is also used to describe raw spatial data object as not only attribute data but also content structurally and semantic ally. There are two issues that motivate this research; 1) what is the spatial information – that materializes the intangible space as a data object, and 2) how we can search the information efficiently – the content-based information retrieval. Although knowledge of a building’s spatial content is most important in architecture, there has been no logical method to manage it.

From the viewpoint of content-based retrieval, the researcher analyzes spatial information of a floor plan, with a focus on the apartment unit floor plan common in Korea. Then the metadata items are extracted in a structured manner. To manage the items efficiently, the researcher develops a data model for spatial information according to the concept of the “Structured Floor Plan”. The main object of content to retrieve is a spatial network that consists of nodes of spaces and their linkages. There are two ways to organize the metadata: the traditional index files and the RDF (Resource Description Framework). While the index files are still efficient with computability, the RDF applies greater options to retrieve, such as fuzzy predicates, semantic predicates, and so on. To exploit the metadata, this research shows several possibilities of query operations that present a set of sample queries about L-DK(Living room – Dining room – Kitchen). Implementation of the prototype system is divided into three parts: 1) a modeling module using Vitruvius; 2) an indexing module using MS SQL Server? 2000 in conjunction XML; and 3) a browsing module using the SpaceScope browser.

The future works may consider XML-based databases and a knowledge based query language, such as RQL/XQL, working on such databases. The more specific domain knowledge is involved, the more practical systems would be. Even in architecture, there may be a diverse range of domain knowledge, such as design, building performance, facility management, energy management, post occupied evaluation, historical research, and so on. Also the issue of interface should be investigated in depth, so that it will be adequate to the needs of the architectural field.

title Communicative Profiles - Generative Art Applied in Information Access Interfaces
source International Conference on Generative Art
summary The path of ubiquitous computing and the domain of ambient intelligence are expected to stimulate emergence of new interaction paradigms. There is a need to develop adequate means of natural communication with an intelligent information system. This, presumably, requires a more integrated development of form and function of the interface. The interface design concept proposed in this paper is based on an evolutionary mechanism and it aims at development of an interactive and adaptive animation system. It is proposed that through a coherent process of adaptation of a system functionality and its appropriate visualization, a personalized and more natural experience of interaction might be achieved.

title Community Building On The Web, Secret Strategies for Successful Online Communities
source Peachpit Press
summary There's been a marked shift in the philosophy of developing successful Web sites. The technologies (HTML, JavaScript, JavaServer Pages) no longer occupy center stage. Rather, functional objectives and the communities that grow up around them seem to be the main ingredient in Web site success. In her carefully reasoned and well-written Community Building on the Web, Amy Jo Kim explains why communities form and grow. More importantly, she shows (with references to many examples) how you can make your site a catalyst for community growth--and profit in the process. From marketing schemes like Amazon.com's Associates program to The Motley Fool's system of rating members' bulletin-board postings, this book covers all the popular strategies for bringing people in and retaining them. Nine core strategies form the foundation of Kim's recommendations for site builders, serving as the organizational backbone of this book. The strategies generally make sense, and they seem to apply to all kinds of communities, cyber and otherwise. (One advocates the establishment of regular events around which community life can organize itself.) Some parts of Kim's message may seem like common sense, but such a coherent discussion of what defines a community and how it can be made to thrive is still helpful.

summary The towers that paint Montreal’s skyline are relics of the 20th century. Towers that express the power of capital on the outside turn out to be almost empty from within. It looks like there was a race to reach the skies - to touch the Mount Royal peak. I remember an attorney working in one of those skyscrapers telling me “the windows are for the lawyers and here in the dark open space is where you can find the slaves.” His words took my imagination to think of a boat in the ancient times where slaves where rowing to the rhythm of the drums. But then I realized the contradiction here - I told him “you should place your ‘slaves’ next to the windows if you want them to be able to row and bring your boat to safe land.”

summary The dogmatic structure of architectural education has meant that the production and application of new educational theories, leading to educational models that use computer technology as their central medium of education, is still a relatively under-explored area. Partial models cannot deliver the expected bigger steps, but only bits and pieces. Curricula developments, at many schools of architecture, have been carried out within the closed circuit manner of architectural education, through expanding the traditional curricula and integrating computers into them. There is still no agreed curriculum in schools of architecture, which defines, at least conceptually, the use of computers within it. Do we really know what we are doing? In the words of Aart Bijl; 'If I want to know what I am doing, I need a separate description of my doing it, a theory' [Bijl, 1989]. The word 'sustainability' is defined as understanding the past and responding to the present with concern for the future. Applying this definition to architectural education, this paper aims to outline the necessity and the principles for the construction of a theory of a sustainable computer aided architectural education model, which could lead to an architectural education that is lasting.

title Universal City
source International Conference on Generative Art
summary "Universal City" is a multimedia performance that documents the evolution of the city in history. Whereas in the past the city was symbolically the world, today the world has become a city. The city rose up in an area once scattered and disorganized for so long that most of its ancient elements of culture were destroyed. It absorbed and re synthesized the remnants of this culture, cultivating power and efficiency. By means of this concentration of physical and cultural power, the city accelerated the rhythm of human relationships and converted their products into forms that are easily stockpiled and reproduced. Along with monuments, written documents and ordered associative organizations amplified the impact of all human activities, extending backwards and forwards over time. Since the beginning however, law and order stood alongside brute force, and power was always determined by these new institutions. Written law served to produce a canon of justice and equality that claimed a higher principle: the king's will, synonymous with divine command. The Urban Neolithic Revolution is comparable only to the Industrial Revolution, and the Media Technology in our own era. There is of course a substantial difference: ours is an era of immeasurable technological progress as an end in itself, which leads to the explosion of the city, and the consequent dissemination of its structure across the countryside. The old walled city has not only fallen, it's buried its foundations. Our civilization flees from every possibility of control, by means of its own extra resources not controllable by the egregious ambitions of man. The image of modern industrialization that Charlie Chaplin resurrected from the past in "Modern Times" is the exact opposite of contemporary metropolitan reality. He figured the worker as a slave chained to his machine and fed by machinery as he continued to work at maintaining the machine itself. Today the workplace is not so brutal, but automation has made it much more oppressive. Energy and dedication once directed towards the production process are today shifted towards consumption. The metropolis in the final phase of its evolution, is becoming a collective mechanism for maintaining the function of this system, and for giving the illusion of power, wealth, happiness, and total success, to those who are, in actuality, its victims. It is a concept foreign to the modern metropolitan mentality that life should be an occasion to Live, and not an excuse for generating newspaper articles, television interviews, or mass spectacles for those who know nothing better. Instead the process continues, until people prefer the simulacrum to the real, where image dominates over object, the copy over the original, representation over reality, appearance over Being. The first phase of the Economy's domination over social life brought about the visible degradation of every human accomplishment from "Being" into "Having". The present phase of social life's total occupation by the accumulated effects of the Economy is leading to a general downslide from "Having" into "Seeming". The performance is based on the instantaneous interaction between video and music: the video component is assembled in real time with RandomCinema a software that I developed and projected on a screen. The music-noise is the product of human radical improvisation togheter automatic-computer process. Everything is based on the consideration of the element of chance as a stimulus for the construction of the most options. The unpredictable helps to reveal things as they happen. The montage, the music, and their interaction, are born and die and the same moment: there are no stage directions or scripts.

summary Literature consists of research identifying the benefits and pitfalls of the use of computer supported collaboration tools and environments to support collaborating design teams (Kvan, 1998; Maher et al, 2000). However, we don’t find enough information in literature about the methodology needed for evaluating the performance of a collaboration environment in meeting the needs and expectations of the collaborating design teams. There are no uniformly accepted methodologies or metrics for evaluating the performance of a design collaboration environment. This paper introduces a requirements-based methodology for evaluating the effectiveness of design collaboration environments. The requirements-based methodology was developed and implemented during a process which involved: a) the use of various synchronous and asynchronous collaboration environments, and b) comparison of those against each other each other by an evaluation methodology. The evaluation methodology proposed in this study is experimented during a course entitled Computer Supported Collaborative Design at the University of Sydney.

title A Virtual Reality Modeling Tool for Students of Architecture
source University of Hong Kong, Hong Kong
summary During a collaborative design session with other universities, several shortcomings, namely long communication response time, lack of common data format for design and ineffective discussion using static image of design, were observed. A solution was proposed by providing a design interface, a. viewing area of the design and a database to store designs and discussion dialogs. This thesis described a VR (virtual reality) modeling tool, the "VR Composer". With the "VR Composer", models are created directly in 3D. This is the design interface of the solution. The "VR Composer" is based on a commercially available VR software. With a head-mounted display, the "VR Composer" immerses the user into a VR environment. This provides a feeling of presence inside the VR environment. New functionality was added to allow user to create and modify objects in VR. There is no common definition for VR.. I have defined VR as Virtual reality is a human-computer interfiwe which allows a user to visualize and interact with the computer-generated three-dimensional environment intuitively. The students of Department of Architecture are requested to test the VR Composer. Although the VR Composer provided basic functionality as a modeling tool, it has to be improvement in many aspects to become an effective tool for modeling.
