title	PUSH: Generating Structural Form with Haptic Feedback

summary	This paper looks into the use of haptic feedback (also known as force feedback) in helping generate and evolve structural forms, a process that is important to students of architecture and engineering. Force feedback provides these students with opportunities to “feel and manipulate” virtual 3D structures in a very natural and intuitive way. It also makes it possible to have real time holistic evaluation of structures in a qualitative rather than quantitative manner, something of particular importance to introductory-level students. Furthermore, the incorporation of force feedback into a highly interactive multimodal structural behavior application furnishes students not only with a means to observe virtual structures but also a tool to help generate and develop efficient, innovative and alternative ones. This also is of vital importance to students of architecture as they are often challenged to explore non-conventional forms. Implementing force feedback systems for these purposes need not necessarily require sophisticated and expensive VR hardware. This paper describes a structural behavior application called PUSH which utilizes a simple force feedback joystick connected a reasonably fast desktop computer.

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

title	Automated Cost Analysis of Concept Design BIM Models
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 403-418.
summary	AUTOMATED COST ANALYSIS OF CONCEPT DESIGN BIM MODELS Interoperability: BIM models and cost models This paper introduces the automated cost analysis developed for the General Services Administration (GSA) and the analysis results of a case study involving a concept design courthouse BIM model. The purpose of this study is to investigate interoperability issues related to integrating design and analysis tools; specifically BIM models and cost models. Previous efforts to generate cost estimates from BIM models have focused on developing two necessary but disjoint processes: 1) extracting accurate quantity take off data from BIM models, and 2) manipulating cost analysis results to provide informative feedback. Some recent efforts involve developing detailed definitions, enhanced IFC-based formats and in-house standards for assemblies that encompass building models (e.g. US Corps of Engineers). Some commercial applications enhance the level of detail associated to BIM objects with assembly descriptions to produce lightweight BIM models that can be used by different applications for various purposes (e.g. Autodesk for design review, Navisworks for scheduling, Innovaya for visual estimating, etc.). This study suggests the integration of design and analysis tools by means of managing all building data in one shared repository accessible to multiple domains in the AEC industry (Eastman, 1999; Eastman et al., 2008; authors, 2010). Our approach aims at providing an integrated platform that incorporates a quantity take off extraction method from IFC models, a cost analysis model, and a comprehensive cost reporting scheme, using the Solibri Model Checker (SMC) development environment. Approach As part of the effort to improve the performance of federal buildings, GSA evaluates concept design alternatives based on their compliance with specific requirements, including cost analysis. Two basic challenges emerge in the process of automating cost analysis for BIM models: 1) At this early concept design stage, only minimal information is available to produce a reliable analysis, such as space names and areas, and building gross area, 2) design alternatives share a lot of programmatic requirements such as location, functional spaces and other data. It is thus crucial to integrate other factors that contribute to substantial cost differences such as perimeter, and exterior wall and roof areas. These are extracted from BIM models using IFC data and input through XML into the Parametric Cost Engineering System (PACES, 2010) software to generate cost analysis reports. PACES uses this limited dataset at a conceptual stage and RSMeans (2010) data to infer cost assemblies at different levels of detail. Functionalities Cost model import module The cost model import module has three main functionalities: generating the input dataset necessary for the cost model, performing a semantic mapping between building type specific names and name aggregation structures in PACES known as functional space areas (FSAs), and managing cost data external to the BIM model, such as location and construction duration. The module computes building data such as footprint, gross area, perimeter, external wall and roof area and building space areas. This data is generated through SMC in the form of an XML file and imported into PACES. Reporting module The reporting module uses the cost report generated by PACES to develop a comprehensive report in the form of an excel spreadsheet. This report consists of a systems-elemental estimate that shows the main systems of the building in terms of UniFormat categories, escalation, markups, overhead and conditions, a UniFormat Level III report, and a cost breakdown that provides a summary of material, equipment, labor and total costs. Building parameters are integrated in the report to provide insight on the variations among design alternatives.

title	The Comparison between Visual Thinking Using Computer and Conventional Media in the Concept Generation Stages of Design
source	CAADRIA '99 [Proceedings of The Fourth Conference on Computer Aided Architectural Design Research in Asia / ISBN 7-5439-1233-3] Shanghai (China) 5-7 May 1999, pp. 363-372

summary	Computer, this new kind of media, has influenced the behavior of design to some degree. Among these years, many researches have appeared for the development of computer-aided design. In recent years, such kind of computer-aided studies about the forepart of design, that is the stage of concept generation, have also started to generate. But most of these researches belonged to the kind of applied studies with the test of computer systems. On the other hand, there were many researches about the visual thinking and cognitive behavior of designers while sketching or drawing in the stage of concept generation. From the synthesis of the fore two disciplines, we can find that there existing a point of deficiency, that is the cognitive research about designers using computers as the sketching media is absent. And that is what I want to study and discuss in this research. The fundamental analytic data of this research is the visual process chronicled form the sketching of subjects, and the assistant analytic data is the verbal data from the questions that the subjects are asked after his/her sketching. These data is analyzed by three coding schema. The cognitive appearance while designers generating concepts with computers or conventional media are propounded and discussed in this research.

title	Esboçando com Gestos: O Projeto 3D SketchMaker (Sketching with Gestures: The 3D SketchMaker Project)
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 141-144
summary	The 3D SketchMaker Project has developed two prototypes for a gestural 3D sketching interface in a computer system to be used in the earliest phases of the design process. The goal of this ongoing research is to provide architects, and other designers involved in object conception, with a 3D gestural instrument that takes advantage of new virtual reality resources and is more natural than using the mouse, less difficult than learning complex software and less abstract than manipulating 2D entities on orthogonal projections. The focus of this project is on the input interface, taking into consideration two factors: First, for many architects and designers, one of the main reasons for not using 3D modeling from the very beginning of the design process is that both current computer hardware and software are hardly appropriate to do the spontaneous and quick drawings that are used to assist in conceptualizing their objects. Second, three-dimensional modeling packages use two-and-three dimensional elements, in a 3D environment, but usually employ 2D input devices that are not appropriate to work in 3D environments, such as mice or pen-and-tablets. The 3D SketchMaker was conceived to take advantage of a natural tendency most people have in using gesture as an aid to language when trying to describe the shape, form or volume of objects. The system is intended to assist or replace the first 2D drawing steps in the design process, generating rough 3D sketches that can be refined later. It is, in essence, a 3D modeling system (a prototype, at this time) directed to do sketching with hand movements and gestures in a virtual reality environment.

title	Formulating a Computer-Aided Architectural Design (CAAD) Program Model in Distance Education (DE) at Open Universities (OU)
source	AVOCAAD Second International Conference [AVOCAAD Conference Proceedings / ISBN 90-76101-02-07] Brussels (Belgium) 8-10 April 1999, pp. 189-204
summary	This paper reports on a project that aims to formulate a CAAD program model in Distance Education (Learning/Teaching) framework, to be applied and implemented in future settings at Open Universities worldwide. The methodology used to establish the CAAD program model consisted of a worldwide literature review on the subject of Distance Education and Open Universities. It also involved an assessment of the methods and means used in the delivery of materials to students enrolled at Open Universities, together with an analysis of the current program of study and subject related courses. The methods of this investigation consisted of a comparative analysis between the existing models of teaching process at Open Universities and how it relates to CAAD in architecture schools. The study endeavored to examine several issues that were found to be key factors in any Open University system, namely: the methods of study, program of study, student type/body, academic/degree requirements, and residency/academic calendars. While attempting to establish a conceptual CAAD program model, this study investigated several questions concerning the efficiency of CAAD teaching in Distance Education. One of the study objectives was to determine which factors were mostly needed to effectively integrate CAAD in DE as a new program in Open Universities. In addition, how would these factors affect the design of CAAD courses in OU systems as a new DE program area? And what structural elements would be most affected by these factors? Another objective of this study was to determine to what extent the new CAAD program model in tandem with staff, learning environment, and administered materials would be effective in generating supplementary strategies in the virtual design studio. A third objective was to evaluate the personal computer station as an alternative design studio space in future settings of schools of architecture. Consequently, the principle objective of this study was to develop and establish a CAAD program model to be adopted by Open Universities as a new subject area in DE. Mainly, the study attempted to locate the areas where CAAD teaching excels in the context of virtual design studio of OU system.

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

title	THE EMERGING DIGITAL STYLE: Attention shift in architectural style recognition

summary	“Style” has long been an important index to observe the design thinking of designers in architecture. Gombrich (1968) defined style as a particular selection from the alternatives when doing things; Ackerman (1963) considered that a distiguishable ensemble of certain characteristics we call a style; Schapiro (1961) pointed out that style is constant forms, and sometimes the constant elements, qualities and expression; Kirsch (1998), Cha and Gero (1999) thought of style as a form element and shape pattern. As Simon and others referred to, style emerged from the process of problem solving, Chan (1994, 2001) ever devised a serious of experiments to set up the operational definitions of style, further five factors that relate to generating styles. Owing to that the greater part of sketches and drawings in the design process couldn’t be replaced by computer-aided design systems (Eisentraut, 1997), designers must shift between different problem-solving methods while facing different design problems. The purpose in this research is to discuss the influences of computer usage on style generation and style recognition: The employment of certain procedural factors that occurred in the design processes that using conventional media is different from the ones that using computer media? Do personal styles emerge while designers shifting between different media in the design processes? Does any unusual phenomenon emerge while accustomed CAD-systems designers recognizing a style?

summary	This paper will present examples of current practice in the Design Studio course of the BDE, University of Strathclyde. The paper will demonstrate an integrated approach to teaching design, which includes CAD among other visual communication techniques as a means to exploring design concepts and the presentation of complex information as part of the design process. It will indicate how the theoretical dimension is used to direct the student in their areas of independent study. Projects illustrated will include design precedents that have involved students in the review and assessment of landmarks in the history of design. There will be evidence of how students integrate DTP in the presentation of site analysis, research of appropriate design precedents and presentation of their design solutions. CADET underlines the importance of considering design solutions within the context of both our European cultural context and of assessing the environmental impact of design options, for which CAD is eminently suited. As much as a critical method is essential to the development of the design process, a historical perspective and an appreciation of the sophistication of communicative media will inform the analysis of structural form and meaning in a modem urban context. Conscious of the dynamic of social and historical influences in design practice, the student is enabled "to take a critical stand against the dogmatism of the school "(Gadamer, 1988) that inevitably insinuates itself in learning institutions and professional practice.

summary	By way of immediate qualification to an essay which attempts to orient current technical developments in relation to a series of dECOi projects, I would suggest that the greatest liberation offered by new technology in architecture is not its formal potential as much as the patterns of creativity and practice it engenders. For increasingly in the projects presented here dECOi operates as an extended network of technical expertise: Mark Burry and his research team at Deakin University in Australia as architects and parametric/ programmatic designers; Peter Wood in New Zealand as programmer; Alex Scott in London as mathematician; Chris Glasow in London as systems engineer; and the engineers (structural/services) of David Glover’s team at Ove Arup in London. This reflects how we’re working in a new technical environment - a new form of practice, in a sense - a loose and light network which deploys highly specialist technical skill to suit a particular project. By way of a second disclaimer, I would suggest that the rapid technological development we're witnessing, which we struggle to comprehend given the sheer pace of change that overwhelms us, is somehow of a different order than previous technological revolutions. For the shift from an industrial society to a society of mass communication, which is the essential transformation taking place in the present, seems to be a subliminal and almost inexpressive technological transition - is formless, in a sense - which begs the question of how it may be expressed in form. If one holds that architecture is somehow the crystallization of cultural change in concrete form, one suspects that in the present there is no simple physical equivalent for the burst of communication technologies that colour contemporary life. But I think that one might effectively raise a series of questions apropos technology by briefly looking at 3 or 4 of our current projects, and which suggest a range of possibilities fostered by new technology. By way of a third doubt, we might qualify in advance the apparent optimism of architects for CAD technology by thinking back to Thomas More and his island ‘Utopia’, which marks in some way the advent of Modern rationalism. This was, if not quite a technological utopia, certainly a metaphysical one, More’s vision typically deductive, prognostic, causal. But which by the time of Francis Bacon’s New Atlantis is a technological utopia availing itself of all the possibilities put at humanity’s disposal by the known machines of the time. There’s a sort of implicit sanction within these two accounts which lies in their nature as reality optimized by rational DESIGN as if the very ethos of design were sponsored by Modern rationalist thought and its utopian leanings. The faintly euphoric ‘technological’ discourse of architecture at present - a sort of Neue Bauhaus - then seems curiously misplaced historically given the 20th century’s general anti-, dis-, or counter-utopian discourse. But even this seems to have finally run its course, dissolving into the electronic heterotopia of the present with its diverse opportunities of irony and distortion (as it’s been said) as a liberating potential.1 This would seem to mark the dissolution of design ethos into non-causal process(ing), which begs the question of ‘design’ itself: who 'designs' anymore? Or rather, has 'design' not become uncoupled from its rational, deterministic, tradition? The utopianism that attatches to technological discourse in the present seems blind to the counter-finality of technology's own accomplishments - that transparency has, as it were, by its own more and more perfect fulfillment, failed by its own success. For what we seem to have inherited is not the warped utopia depicted in countless visions of a singular and tyrranical technology (such as that in Orwell's 1984), but a rich and diverse heterotopia which has opened the possibility of countless channels of local dialect competing directly with the channels of power. Undoubtedly such multiplicitous and global connectivity has sent creative thought in multiple directions…

title	An Epistemological and Systems Approach to Digital Technology Integration in Architectural Curriculum
source	Media and Design Process [ACADIA ‘99 / ISBN 1-880250-08-X] Salt Lake City 29-31 October 1999, pp. 16-26

summary	Architectural institutions around the world have been faced with the question of digital technology integration for the last one decade. Numerous attempts have been made by those institutions to utilize and harness the new technology by trial and error methods. Although much has been said and done about the computer as a tool and a medium, there is a great paucity of well-considered and holistic theoretical frameworks that have been successfully applied in architectural curricula. The emergence of digital technology as an environment and as an overarching system has NOT been a much understood or acknowledged fact. This lack of systemic wisdom, in the digital technology integration process, is always punished by the system. In this paper, I intend to 1.) Outline the epistemological, philosophical, pedagogical and operational issues of digital technology integration efforts undertaken at Kansas State University. 2.) Meditate a systemic and holistic framework of principles, paradigms, proposals and strategies from a systems point of view that could be applied at other educational institutions. In contradistinction to the analytical, hierarchical and prosthetic approaches frequently adapted by the architectural institutions, I propose a systems approach and an ecological paradigm to understand and comprehensively integrate digital technology with architectural curricula. While many of the ideas brought under the framework may not be new, the framework itself is a new proposition. The framework draws heavily from Jean-François Lyotard’s postmodern pedagogical work, Deleuze and Guattari’s post-structural notions of “rhizome”, and Gregory Bateson’s expositions of ecological and systems approach.

title	Playing with Digital Media: Enlivening Computer Graphics Teaching
source	Media and Design Process [ACADIA ‘99 / ISBN 1-880250-08-X] Salt Lake City 29-31 October 1999, pp. 96-109

summary	Are there better ways of getting a student to learn? Getting students to play at learning can encourage comprehension by engaging their attention. Rather than having students' fascination with video games and entertainment limited to competing against learning, we can direct this interest towards learning computer graphics. We hypothesize that topics having a recreational component increase the learning curve for digital media instruction. To test this, we have offered design media projects with a playful element as a counterpart to more step-by-step descriptive exercises. Four kinds of problems, increasing in difficulty, are discussed in the context of computer aided architectural design education: 1) geometry play, 2) kit of parts, 3) dreams from childhood and 4) transformations. The problems engage the students in different ways: through playing with form, by capturing their imagination and by encouraging interaction. Each type of problem exercises specific design skills while providing practice with geometric modeling and rendering. The problems are sequenced from most constrained to most free, providing achievable milestones with focused objectives. Compared to descriptive assignments and more serious architectural problems, these design-oriented exercises invite experimentation by lowering risk, and neutralize stylistic questions by taking design out of the traditional architectural context. Used in conjunction with the modeling of case studies, they engage a wide range of students by addressing different kinds of issues. From examining the results of the student work, we conclude that play as a theme encourages greater degree of participation and comprehension.

summary	This article reports on the recent, geographically and temporally distributed, intercollegiate Virtual Design Studio based on the 1998 implementation Phase(x) environment. Students participating in this workshop had to create a place to wait in the form of a folly. This design task was cut in five logical parts, called phases. Every phase had to be finished within a specific timeframe (one day), after which the results would be stored in a common data repository, an online MSQL database environment which holds besides the presentations, consisting of text, 3D models and rendered images, basic project information like the descriptions of the phases and design process visualization tools. This approach to collaborative work is better known as memetic engineering and has successfully been used in several educational programs and past Virtual Design Studios. During the workshop, students made use of a variety of tools, including modeling tools (specifically Sculptor), video-conferencing software and rendering programs. The project distinguishes itself from previous Virtual Design Studios in leaving the design task more open, thereby focusing on the design process itself. From this perspective, this paper represents both a continuation of existing reports about previous Virtual Design Studios and a specific extension by the offered focus. Specific attention will be given at how the different collaborating parties dealt with the data flow and modification, the crux within a successful effort to cooperate on a common design task.

source	AVOCAAD Second International Conference [AVOCAAD Conference Proceedings / ISBN 90-76101-02-07] Brussels (Belgium) 8-10 April 1999, pp. 285-291
summary	This paper describes Transducer, a prototype digital system for live, audio-visual performance. Currently the process of editing sounds or crafting three-dimensional structures on a computer remains a frustratingly rigid process. Current tools for real-time audio or visual construction using computers involve obtuse controls, either heavily GUI'ed or overstylized. Transducer asks one to envision a space where the process of editing and creating on a computer becomes a dynamic performance. The content of this performance may be sufficiently complex to elicit multiple interpretations, but Transducer enforces the notion that the process of creation should itself be a fluid and transparent expression. The system allows a performer to build constructions of sampled audio and computational three-dimensional form simultaneously. Each sound clip is visualized as a "playable" cylinder of sound that can be manipulated both visually and aurally in real-time. The transducer system demonstrates a creative space with equal design detailing at both the construction and performance phase.

title	Networking: media, representation and architecture
source	Timmermans, Harry (Ed.), Fifth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Nijkerk, the Netherlands)
summary	In this paper we present a pedagogic work, carried out in a third year architecture course, focused on the relationship between teaching content and media. The subject-matter of the course is the concept of representation; an eminently philosophical issue which transcends the limits of a particular discipline. The media that have been used are mostly the web, along with other standard programs to process text and images, create models and animations. The core of this research work is the course ‘Sistemas de Representación’, which has taken place for the first time in the academic year 1999/00. The course is structured in six themes, each one standing for a system of representation: TEXT, FIGURE, OBJECT, IMAGE, SPACE and LIGHT. Within every system, a variety of topics dealing with the concept of representation are addressed in an interdisciplinary manner. A web based learning environment named NETWORKING has been created especially for the course. This environment allows students to perform a variety of collaborative works: drawing visual and linguistic relationships, developing further the works of other students, and participating in collective processes of form generation and space perception.

doi	https://doi.org/10.52842/conf.ecaade.2000.085
summary	Recent years have seen the increasing use of digital media in undergraduate architectural education at UND, and which has been fuelled by students themselves taking up the tools available to practising architects. This process of self-selection may hold valuable lessons for the development of architectural curricula. An experimental design studio offered as an elective to UND undergraduates in 1999 has indicated that the design work produced therein, most often differed remarkably from the previous work of the same students using only traditional media. In so far as digital environments rapidly provide new and strange objects and images for students to encounter, those students are driven to interpret, transform or customise that environment in innovative ways, thereby making it their own. It is clear that the full integration of digital environments into architectural education will profoundly effect the outcomes of student work. We have observed that some self-selecting students struggle in expressing ideas through repre-sentative form in traditional studios. The question arises whether these students are "onto something" which they intuitively understand as better suited to their abilities, or whether in fact they are see digital tools as a means to avoid those areas in design in which they experience difficulties. Through observation of a group of "self-selectors" the authors attempt to lead useful generalisations; to develop a theory and method for facilitators to deal with specific students; and to work toward the development of suitable curricula for these cases.

summary	The projectual disciplines must respond with some grade of originality to a approached problem. In order to products of design be creative must be implemented a creative process of design and also from the teaching. The essence of creativity are the variations over a subject. A pedagogic way for this, is the one to recognise, individualise and represent the problem attributes, building upon them an "exploration space", to analyse and create new combinatorial alternatives or restructuring of the problem. The digital media incorporation as a new proyectual environment approaches the interactivity not only of the combinatorial variables, but, also to the hypermedia's. Both the digital documents, as the creative process, have a "no linear" or a "net" structure, that allows the construction of a himself way, self-managemented into this structure. The interactivity makes possible to work, as the divergent thought does, in a "polydirectional" field, that stimulates the fluency, the flexibility and the originality. The new- media's, used as didactic tool, open to "action", allow the students to convert them in "co- author", together professors, about themself learning process. >From this educational conception and its potential enrichment with the hypermedia, we are designing a project of digitising of an exercise to our didactic proposal and its later application into the course with our students.

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	In the very young discipline of Virtual Reality Applications only a few reports are available about using this technology for periods longer than in experimental setups. This paper describes experiences made during five years of usage of Virtual Reality (VR) in educational training for architects. About 100 different people were working with our systems during this period. Three programs were developed at Bauhaus University with the aim of teaching architectural students to design in three-dimesional environments. The first program called voxDesign is based on the metaphor of voxels. The second program, planeDesign, uses rectangualar planes to describe room-like situations. An other program vram for the user orientated description of flexible and own interfaces and environments is current under construction, a first verson is presented at the international computer exhibition ìCeBitî in 1999. All programs force the users to design in a 1:1 scale, that means that the design and the feedback actions are coupled in an embodied way. A real walking metaphor is used for navigation. The experiences made by users are explained too.

summary	This paper describes the three generations of CAD systems. The first generation of (primarily analytical) computer programmes really aided designing. These programmes were the tools for finding a functional solution in different areas of designing, from flat plans to the space organisation of a hospital. One of the shortcomings of these programmes was the lack of graphic interface. With time, however, this kind of interface was developed. As a result of this second generation of CAD systems the computer was transformed into a drafting machine and CAD meant Computer Aided Drafting. The main thesis of this consideration is that only now we have the chance to return to the idea of Computer Aided Design. One of the examples of these trends is the AVOCAAD programme in which Added Value of CAAD is analysed. The development of the third generation of CAD systems will be possible in the near future. Aiding the process of designing will demand the elaboration of new methods of using the computer at the early stages of this process. The computer should be used not for generating variants of functional solutions only but for also for the creation of 3D forms by 3D sketching. For this, the computer should be transformed from a tool into a medium; only then will designing become true Designing in Cyber Space.
