title	Object shape and reflectance modeling from observation
source	Proceedings of SIGGRAPH 97, pp. 379-387, August, 1997
summary	An object model for computer graphics applications should contain two aspects of information: shape and reflectance properties of the object. A number of techniques have been developed for modeling object shapes by observing real objects. In contrast, attempts to model reflectance properties of real objects have been rather limited. In most cases, modeled reflectance properties are too simple or too complicated to be used for synthesizing realistic images of the object. In this paper, we propose a new method for modeling object reflectance properties, as well as object shapes, by observing real objects. First, an object surface shape is reconstructed by merging multiple range images of the object. By using the reconstructed object shape and a sequence of color images of the object, parameters of a reflection model are estimated in a robust manner. The key point of the proposed method is that, first, the diffuse and specular reflection components are separated from the color image sequence, and then, reflectance parameters of each reflection component are estimated separately. This approach enables estimation of reflectance properties of real objects whose surfaces show specularity as well as diffusely reflected lights. The recovered object shape and reflectance properties are then used for synthesizing object images with realistic shading effects under arbitrary illumination conditions.

title	Toward a procedure of computer simulation in the restoration of historical architecture
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 the field of architectural design, “visualization¨ generally refers to some media, communicating and representing the idea of designers, such as ordinary drafts, maps, perspectives, photos and physical models, etc. (Rahman, 1992; Susan, 2000). The main reason why we adopt visualization is that it enables us to understand clearly and to control complicated procedures (Gombrich, 1990). Secondly, the way we get design knowledge is more from the published visualized images and less from personal experiences (Evans, 1989). Thus the importance of the representation of visualization is manifested.Due to the developments of computer technology in recent years, various computer aided design system are invented and used in a great amount, such as image processing, computer graphic, computer modeling/rendering, animation, multimedia, virtual reality and collaboration, etc. (Lawson, 1995; Liu, 1996). The conventional media are greatly replaced by computer media, and the visualization is further brought into the computerized stage. The procedure of visual impact analysis and assessment (VIAA), addressed by Rahman (1992), is renewed and amended for the intervention of computer (Liu, 2000). Based on the procedures above, a great amount of applied researches are proceeded. Therefore it is evident that the computer visualization is helpful to the discussion and evaluation during the design process (Hall, 1988, 1990, 1992, 1995, 1996, 1997, 1998; Liu, 1997; Sasada, 1986, 1988, 1990, 1993, 1997, 1998). In addition to the process of architectural design, the computer visualization is also applied to the subject of construction, which is repeatedly amended and corrected by the images of computer simulation (Liu, 2000). Potier (2000) probes into the contextual research and restoration of historical architecture by the technology of computer simulation before the practical restoration is constructed. In this way he established a communicative mode among archeologists, architects via computer media.In the research of restoration and preservation of historical architecture in Taiwan, many scholars have been devoted into the studies of historical contextual criticism (Shi, 1988, 1990, 1991, 1992, 1995; Fu, 1995, 1997; Chiu, 2000). Clues that accompany the historical contextual criticism (such as oral information, writings, photographs, pictures, etc.) help to explore the construction and the procedure of restoration (Hung, 1995), and serve as an aid to the studies of the usage and durability of the materials in the restoration of historical architecture (Dasser, 1990; Wang, 1998). Many clues are lost, because historical architecture is often age-old (Hung, 1995). Under the circumstance, restoration of historical architecture can only be proceeded by restricted pictures, written data and oral information (Shi, 1989). Therefore, computer simulation is employed by scholars to simulate the condition of historical architecture with restricted information after restoration (Potier, 2000). Yet this is only the early stage of computer-aid restoration. The focus of the paper aims at exploring that whether visual simulation of computer can help to investigate the practice of restoration and the estimation and evaluation after restoration.By exploring the restoration of historical architecture (taking the Gigi Train Station destroyed by the earthquake in last September as the operating example), this study aims to establish a complete work on computer visualization, including the concept of restoration, the practice of restoration, and the estimation and evaluation of restoration.This research is to simulate the process of restoration by computer simulation based on visualized media (restricted pictures, restricted written data and restricted oral information) and the specialized experience of historical architects (Potier, 2000). During the process of practicing, communicates with craftsmen repeatedly with some simulated alternatives, and makes the result as the foundation of evaluating and adjusting the simulating process and outcome. In this way we address a suitable and complete process of computer visualization for historical architecture.The significance of this paper is that we are able to control every detail more exactly, and then prevent possible problems during the process of restoration of historical 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".

title	Rationale-Supported Mixed-Initiative Case-Based Planning
source	Proceedings of IAAI-97
summary	Mixed initiative planning envisions a framework in which automated and human planners interact to jointly construct plans that satisfy specific objectives. In this paper, we report on our work engineering a robust mixedinitiative planning system. Human planners rely strongly on past planning experience to generate new plans. ForMAT is a casebased system that supports human planning through the accumulation of userbuilt plans, querydriven browsing of past plans, and several plan functionality analysis primitives. Prodigy/Analogy is an automated AI planner that combines generative and casebased planning. Stored plans are annotated with plan rationale and reuse involves adaptation driven by this rationale. Our system, MICBP, integrates ForMAT and Prodigy/Analogy into a realtime messagepassing mixedinitiative planning system. The main technical approach consists of allowing the user to specify and link objectives that enable the system to capture and reuse plan rationale. We present MICBP and its concrete application to the domain of military force deployment planning. This synergistic system increases the planning efficiency of human planners through automated suggestion of similar past plans and plausible plan modifications.

title	Generic Representations - Typical Design without the Use of Types
source	CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 117-133
summary	The building type is a (knowledge) structure that is both recognised as a constitutive cognitive element of human thought and as a constitutive computational element in CAAD systems. Questions that seem unresolved up to now about computational approaches to building types are the relationship between the various instances that are generally recognised as belonging to a particular building type, the way a type can deal with varying briefs (or with mixed functional use), and how a type can accommodate different sites. Approaches that aim to model building types as data structures of interrelated variables (so-called 'prototypes') face problems clarifying these questions. It is proposed in this research not to focus on a definition of 'type,' but rather to investigate the role of knowledge connected to building types in the design process. The basic proposition is that the graphic representations used to represent the state of the design object throughout the design process can be used as a medium to encode knowledge of the building type. This proposition claims that graphic representations consistently encode the things they represent, that it is possible to derive the knowledge content of graphic representations, and that there is enough diversity within graphic representations to support a design process of a building belonging to a type. In order to substantiate these claims, it is necessary to analyse graphic representations. In the research work, an approach based on the notion of 'graphic units' is developed. The graphic unit is defined and the analysis of graphic representations on the basis of the graphic unit is demonstrated. This analysis brings forward the knowledge content of single graphic representations. Such knowledge content is declarative knowledge. The graphic unit also provides the means to articulate the transition from one graphic representation to another graphic representation. Such transitions encode procedural knowledge. The principles of a sequence of generic representations are discussed and it is demonstrated how a particular type - the office building type - is implemented in the theoretical work. Computational work on implementation part of a sequence of generic representations of the office building type is discussed. The paper ends with a summary and future work.

title	Computer analysis of visual perception - endoscopy without endoscope
source	Architectural and Urban Simulation Techniques in Research and Education [Proceedings of the 3rd European Architectural Endoscopy Association Conference / ISBN 90-407-1669-2]
summary	This paper presents a method of using computer animation techniques in order to solve problems of visual pollution of city environment. It is our observation that human-inducted degradation of city environmental results from well - intentioned but inappropriate preservation actions by uninformed designers and local administration. Very often, a local municipality administration permits to build bad-fitting surroundings houses. It is usually connected with lack of visual information's about housing areas of a city, its features and characteristics. The CAMUS system (Computer Aided Management of Urban Structure) is being created at the Faculty of Architecture of Bialystok Technical University. One of its integral parts is VIA - Visual Impact of Architecture. The basic element of this system is a geometrical model of the housing areas of Bialystok. This model can be enhanced using rendering packages as they create the basis to check our perception of a given area. An inspiration of this approach was the digital endoscopy presented by J. Breen and M. Stellingwerff at the 2nd EAEA Conferences in Vienna. We are presenting the possibilities of using simple computer programs for analysis of spatial model. This contribution presents those factors of computer presentation which can demonstrate that computers achieve such effects as endoscope and often their use be much more efficient and effective.

summary	So far yet, even the most advanced technology has not been able to substitute a human, his thoughts, feelings, dreams, longings, visions. It can though, removing need for all kind of effort from our everyday life, surrounding a human with unprecedented comfort, create feeling of peace and security. Task of a computer is to provide assistance, helping in calculations, forming of refined solids, It contains a compendium of knowledge and memory - but not creative skills. So far it's only a machine, with help of which a possibility of creative expression is expanded. It only can solve problems for a human faster and more efficient way, does not have the ability to describe (formulate) problems. Even while providing a support, does it do that honestly? It means, does it support us in those of our doings where we truly need it? Computers have enormous possibilities of use that are not exploited sufficiently and all the time new generations of yet quicker machines with unbelievable power are being created. Every new type of computer appears to be obsolete and insufficient within a few months. Insufficient for what?

title	Cyber(Inter)Sections: Looking into the Real Impact of The Virtual in the Architectural Profession
source	Proceedings of the Symposium on Architectural Design Education: Intersecting Perspectives, Identities and Approaches. Minneapolis, MN: College of Architecture & Landscape Architecture, pp. 57-63
summary	As both the skepticism and 'hype' surrounding cyberspace vanish under the weight of ever increasing power, demand, and use of information, the architectural discipline must prepare for significant changes. For cyberspace is remorselessly cutting through the dearest structures, rituals, roles, and modes of production in our profession. Yet, this section is not just a detached cut through the existing tissues of the discipline. Rather it is an inter-section, as cyberspace becomes also transformed in the act of piercing. This phenomenon is causing major transformations in at least three areas: 1. Cyberspace is substantially altering the way we produce and communicate architectural information. The arising new working environment suggests highly hybrid and networked conditions that will push the productive and educational landscape of the discipline towards increasing levels of fluidity, exchanges, diversity and change. 2. It has been argued that cyberspace-based human and human-data interactions present us with the opportunity to foster a more free marketplace of ideologies, cultures, preferences, values, and choices. Whether or not the in-progress cyberincisions have the potential to go deep enough to cure the many illnesses afflicting the body of our discipline need to be considered seriously. 3. Cyberspace is a new place or environment wherein new kinds of human activities demand unprecedented types of architectural services. Rather than being a passing fashion, these new architectural requirements are destined to grow exponentially. We need to consider the new modes of practice being created by cyberspace and the education required to prepare for them. This paper looks at these three intersecting territories showing that it is academia and not practice that is leading the profession in the incorporation of virtuality into architecture. Rafael Moneo's words come to mind. [2]

title	RealSpace in QuickTimes: architecture and digitization
source	Rotterdam: Nai Publishers
summary	Time and space, drastically compressed by the computer, have become interchangeable. Time is compressed in that once everything has been reduced to 'bits' of information, it becomes simultaneously accessible. Space is compressed in that once everything has been reduced to 'bits' of information, it can be conveyed from A to B with the speed of light. As a result of digitization, everything is in the here and now. Before very long, the whole world will be on disk. Salvation is but a modem away. The digitization process is often seen in terms of (information) technology. That is to say, one hears a lot of talk about the digital media, about computer hardware, about the modem, mobile phone, dictaphone, remote control, buzzer, data glove and the cable or satellite links in between. Besides, our heads are spinning from the progress made in the field of software, in which multimedia applications, with their integration of text, image and sound, especially attract our attention. But digitization is not just a question of technology, it also involves a cultural reorganization. The question is not just what the cultural implications of digitization will be, but also why our culture should give rise to digitization in the first place. Culture is not simply a function of technology; the reverse is surely also true. Anyone who thinks about cultural implications, is interested in the effects of the computer. And indeed, those effects are overwhelming, providing enough material for endless speculation. The digital paradigm will entail a new image of humankind and a further dilution of the notion of social perfectibility; it will create new notions of time and space, a new concept of cause and effect and of hierarchy, a different sort of public sphere, a new view of matter, and so on. In the process it will indubitably alter our environment. Offices, shopping centres, dockyards, schools, hospitals, prisons, cultural institutions, even the private domain of the home: all the familiar design types will be up for review. Fascinated, we watch how the new wave accelerates the process of social change. The most popular sport nowadays is 'surfing' - because everyone is keen to display their grasp of dirty realism. But there is another way of looking at it: under what sort of circumstances is the process of digitization actually taking place? What conditions do we provide that enable technology to exert the influence it does? This is a perspective that leaves room for individual and collective responsibility. Technology is not some inevitable process sweeping history along in a dynamics of its own. Rather, it is the result of choices we ourselves make and these choices can be debated in a way that is rarely done at present: digitization thanks to or in spite of human culture, that is the question. In addition to the distinction between culture as the cause or the effect of digitization, there are a number of other distinctions that are accentuated by the computer. The best known and most widely reported is the generation gap. It is certainly stretching things a bit to write off everybody over the age of 35, as sometimes happens, but there is no getting around the fact that for a large group of people digitization simply does not exist. Anyone who has been in the bit business for a few years can't help noticing that mum and dad are living in a different place altogether. (But they, at least, still have a sense of place!) In addition to this, it is gradually becoming clear that the age-old distinction between market and individual interests are still relevant in the digital era. On the one hand, the advance of cybernetics is determined by the laws of the marketplace which this capital-intensive industry must satisfy. Increased efficiency, labour productivity and cost-effectiveness play a leading role. The consumer market is chiefly interested in what is 'marketable': info- and edutainment. On the other hand, an increasing number of people are not prepared to wait for what the market has to offer them. They set to work on their own, appropriate networks and software programs, create their own domains in cyberspace, domains that are free from the principle whereby the computer simply reproduces the old world, only faster and better. Here it is possible to create a different world, one that has never existed before. One, in which the Other finds a place. The computer works out a new paradigm for these creative spirits. In all these distinctions, architecture plays a key role. Owing to its many-sidedness, it excludes nothing and no one in advance. It is faced with the prospect of historic changes yet it has also created the preconditions for a digital culture. It is geared to the future, but has had plenty of experience with eternity. Owing to its status as the most expensive of arts, it is bound hand and foot to the laws of the marketplace. Yet it retains its capacity to provide scope for creativity and innovation, a margin of action that is free from standardization and regulation. The aim of RealSpace in QuickTimes is to show that the discipline of designing buildings, cities and landscapes is not only a exemplary illustration of the digital era but that it also provides scope for both collective and individual activity. It is not just architecture's charter that has been changed by the computer, but also its mandate. RealSpace in QuickTimes consists of an exhibition and an essay.

summary	Computer Numeric Controlled (CNC) fabrication machineries are changing the way we design and build. These technologies have increased productivity through greater efficiencies and have helped to create new forms of practice, including increased specializations and broader collaborative approaches. (Kieran Timberlake 2003: 31). However, some argue that these technologies can have a de-humanizing effect, stripping the human touch away from the production of objects and redistributing the associated skills to machines. (Dormer 1997: 103). The (Digital) Craft studio explored the notions of technology and craft to understand how and when designers should exploit the tools employed (both the hand and the machine) during the design and production processes.

title	Modelling for eye level composition; design media experiments in an educational setting.
source	Architectural and Urban Simulation Techniques in Research and Education [Proceedings of the 3rd European Architectural Endoscopy Association Conference / ISBN 90-407-1669-2]
summary	In order to simulate the visual effects of designs at eye level, it is necessary to construct models from which (sequences of) images can be taken. This holds true for both Optical Endoscopy and Computer Aided Visualisation techniques. In what ways can an eye level approach stimulate spatial awareness and create insights into the workings of a design concept? Can Endoscopic methods be used effectively as a creative environment for design decision-making and teamwork and even to stimulate the generation of new design ideas? How should modelmaking be considered if it is to be of use in an ‘impatient’ design process, and how can students be made aware of the opportunities of both direct eye level observations from design models and of the more sophisticated endoscopic imaging techniques? This paper explores the theme of eye level modelling by focusing on a number of formal exercises and educational experiments carried out by the Delft Media group in recent years. An attempt is made to describe and evaluate these experiences, in order to draw conclusions and to signal possible new opportunities for eye level composition for the benefit of both design education and practice...

title	Integrating Design Tools within a Human Collaborative Working Context
source	International Journal of Construction IT, Vol5, No 2, pp 35-53
summary	Integrating design tools has been an important research subject. The work to be reported in this paper differs from many previous efforts in that it not only tackles tool-tool interoperation, but also does so within a human collaborative working context We suggest that design integration support should include not only tool interoperability, but also mechanisms for co-ordinate and control the tool use. We also argue that the higher-level management support should include not only formalised and automated mechanisms, but also semi-automated and even informal mechanisms for human designers to directly interact with each other. Within a collaborative working framework, we'll present a hybrid architecture for tool integration, in which the human designers and the design tools are assumed to be distributed while the management is centralised. In this approach, each design tool is wrapped as an autonomous service provider with its own data store; thus the project design data is physically distributed with the design tools. A meta-data augmented product model, which populates a central meta-data repository serving as a "map" for locating the distributed design objects, is devised to provide a common vocabulary for communications and to assist the management of the distributed resources and activities. A design object broker is used to mediate among the distributed tools, and the central meta-data repository. The reported work has been part of a collaborative design system called virtual studio environment We'll illustrate how the integrated design tools might be used in human design work within the virtual studio environment.

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.

In the analogical reasoning process, case adaptation is the fundamental task for solving the problem. This paper is aimed to study the difference between human designers and computers in case adaptation. Two design experiments are undertaken for examining how designers apply dimensional and topological adaptation, exploring the difference of case adaptation by novice and experienced designers, and examining the difference between human judgement in case adaptation and the evaluation mechanism by providing similarity assessment.

title	Multi-sensory user interface for a virtual-reality-based computer-aided design system
source	Computer-Aided Design, Vol. 29 (10) (1997) pp. 709-725
summary	The generation of geometric shapes called `geometric concept designs' via the multi-sensory user interface of a virtual reality (VR) based system motivates the currentresearch. In this new VR-based system, geometric designs can be more effectively inputted into the computer in a physically intuitive way. The interaction mechanism issimilar to the way in which industrial designers sit and discuss concept design shapes across a table from each other, prior to making a final decision about the productdetails. By using different sensory modalities, such as voice, hand motions and gestures, product designers can convey design ideas through the VR-basedcomputer-aided design (CAD) system. In this scenario, the multi-sensory interface between human and computer plays a central role with respect to usability, usefulnessand accuracy. The current paper focuses on determining the requirements for the multi-sensory user interface and assessing the applications of different input and outputmechanisms in the virtual environment (VE). In order to evaluate this multi-sensory user interface, this paper formulates the typical activities in product shape design intoa set of requirements for the VR-CAD system. On the basis of these requirements, we interviewed typical CAD users about the effectiveness of using different sensoryinput and output interaction mechanisms such as visual, auditory and tactile. According to the results of these investigations, a nodal network of design activity thatdefines the multi-sensory user interface of the VR-CAD system is determined in the current research. The VR-CAD system is still being developed. However, voicecommand input, hand motion input, three-dimensional visual output and auditory output have been successfully integrated into the current system. Moreover, severalmechanical parts have been successfully created through the VR interface. Once designers use the VR-CAD system that we are currently developing, the interfacerequirements determined in the current paper may be verified or refined. The objectives of the current research are to expand the frontiers of product design and establisha new paradigm for the VR-based conceptual shape design system.

doi	https://doi.org/10.52842/conf.ecaade.1997.x.n7x
summary	n a previous paper the authors presented an analyser of simple architectural images. It works at syntactical level inasmuch as it is able to detect the elementary components of the images and to perform on them some analyses regarding their reciprocal position and their combinations. Here we present a second step of development of the analyser: the implementation of some semantic capabilities. The most elementary level of semantics is the simple recognition of each object present in the architectural image. Which, in turn means attributing to each object the name of the class of similar objects to which the single object is supposed to pertain. While at the syntactical level the pertinence to a class implies the identity of an object to the class prototype, at the semantic level this is not compulsory. Pertaining to the same class, that is having the same architectural meaning, can be objects having approximately the same shape. Consequently in order to detect the pertinence of an object to a class, that is giving it an architectural meaning, two things are necessary: a date base containing the class prototypes to which the recognized objects are to be assigned and a tool able to "measure" the difference of two shapes.

title	A Software for Automatically Verifying Compatibility in Complicated Building Assemblies
source	Challenges of the Future [15th eCAADe Conference Proceedings / ISBN 0-9523687-3-0] Vienna (Austria) 17-20 September 1997

summary	The research we are carrying on is intended to develop a tool aiding to design building mechanical assembly systems, which are often characterised by high complexity levels. In fact, when designing complicated building assemblies by making use of common graphical representations, it might be impossible for the operator to choose the proper shape and installation sequence of components so that they do not interfere during the assembly, and to check, in the meantime, the most favorable setting up modalities according to execution problems. Our software, running within CAD, by starting from the definition of the node features, will allow the operator to automatically get three types of representation that can simulate the assembly according to the assigned installation sequence: - instant images of the phases for setting up each component into the node; - 3D views showing the position of each component disassembled from the node and indicating the movements required for connection; - the components moving while the node is being constructed. All the representations can be updated step by step each time modifications to the node are made. Through this digital iterative design process - that takes advantage of various simultaneous and realistic prefigurations - the shape and function compatibility between the elements during the assembling can be verified. Furthermore, the software can quickly check whether any change and integration to the node is efficacious, rising the approximation levels in the design phase. At the moment we have developed the part of the tool that simulates the assembly by moving the components into the nodes according to the installation sequence.
