title Information Sharing in Building Design
source Proceedings of the Eighth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-8536-5] Atlanta, 7-8 June 1999, pp. 165-183
summary We address information modeling and exchange in asynchronous, distributed collaboration between software applications or design agents that are heterogeneous, that is, developed independently based on application- specific data models. We identify the requirements an integration environment must satisfy if it is to support the semantically correct exchange of selected, locally generated information between the agents. These requirements are distilled from both the literature and our own experiments with the Object Modeling Language OML. The resulting requirements were then formalized into an information modeling and exchange environment constructed around the modeling language called SPROUT (supported by a compiler) and an associated software architecture that can be targeted toward many different hardware and software platforms. A unique capability supported in this environment is formal support for integrating existing applications: Given a schematic description in SPROUT, a formal specification can be used to generate computer programs that provably map data to and from the applications.

title Architectural Innovation as an evolutionary process
source International Conference on Generative Art
summary Traditionally in art and architectural history, innovation is treated as a history of ideas of individuals (pioneers), movements and schools. The monograph is in that context one of the most used forms of scientific exercise. History of architecture is then mostly seen as a succession of dominant architectural paradigms imposed by great architectural creators fighting at the beginning against mainstream establishment until they themselves come to be recognised. However, there have been attempts to place architectural innovation and creativity in an evolutionary perspective. Charles Jencks for example, has described the evolution of architectural and art movements according to a diagram inspired by ecological models. Philip Steadman, in his book "The Evolution of Designs. Biological analogy in architecture and the applied arts" (1979), sketches the history of various biological analogies and their impact on architectural theory: the organic, classificatory, anatomical, ecological and Darwinian or evolutionary analogies. This last analogy "explains the design of useful objects and buildings, particularly in primitive society and in the craft tradition, in terms of a sequence of repeated copyings (corresponding to inheritance), with small changes made at each stage ('variations'), which are then subjected to a testing process when the object is put into use ('selection')." However, Steadman has confined his study to a literature survey as the basis of a history of ideas. Since this pioneering work, new developments like Dawkins' concept of memes allow further steps in the field of cultural evolution of architectural innovation. The application of the concept of memes to architectural design has been put forward in a preceding "Generative Art" conference (Daru, 1999), showing its application in a pilot study on the analysis of projects of and by architectural students. This first empirical study is now followed by a study of 'real life' architectural practice. The case taken has a double implication for the evolutionary analogy. It takes a specific architectural innovative concept as a 'meme' and develops the analysis of the trajectory of this meme in the individual context of the designer and at large. At the same time, the architect involved (Eric Vreedenburgh, Archipel Ontwerpers) is knowledgeable about the theory of memetic evolution and is applying a computer tool (called 'Artificial') together with Remko Scha, the authoring computer scientist of the program who collaborates frequently with artists and architects. This case study (the penthouse in Dutch town planning and the application of 'Artificial') shall be discussed in the paper as presented. The theoretical and methodological problems of various models of diffusion of memes shall be discussed and a preliminary model shall be presented as a framework to account for not only Darwinian but also Lamarckian processes, and for individual as well as collective transmission, consumption and creative transformation of memes.

title ArTbitrariness in Music
source International Conference on Generative Art
summary Evolution is now considered not only powerful enough to bring about the biological entities as complex as humans and conciousness, but also useful in simulation to create algorithms and structures of higher levels of complexity than could easily be built by design. In the context of artistic domains, the process of human-machine interaction is analyzed as a good framework to explore creativity and to produce results that could not be obtained without this interaction. When evolutionary computation and other computational intelligence methodologies are involved, every attempt to improve aesthetic judgement we denote as ArTbitrariness, and is interpreted as an interactive iterative optimization process. ArTbitrariness is also suggested as an effective way to produce art through an efficient manipulation of information and a proper use of computational creativity to increase the complexity of the results without neglecting the aesthetic aspects [Moroni et al., 2000]. Our emphasis will be in an approach to interactive music composition. The problem of computer generation of musical material has received extensive attention and a subclass of the field of algorithmic composition includes those applications which use the computer as something in between an instrument, in which a user "plays" through the application's interface, and a compositional aid, which a user experiments with in order to generate stimulating and varying musical material. This approach was adopted in Vox Populi, a hybrid made up of an instrument and a compositional environment. Differently from other systems found in genetic algorithms or evolutionary computation, in which people have to listen to and judge the musical items, Vox Populi uses the computer and the mouse as real-time music controllers, acting as a new interactive computer-based musical instrument. The interface is designed to be flexible for the user to modify the music being generated. It explores evolutionary computation in the context of algorithmic composition and provides a graphical interface that allows to modify the tonal center and the voice range, changing the evolution of the music by using the mouse[Moroni et al., 1999]. A piece of music consists of several sets of musical material manipulated and exposed to the listener, for example pitches, harmonies, rhythms, timbres, etc. They are composed of a finite number of elements and basically, the aim of a composer is to organize those elements in an esthetic way. Modeling a piece as a dynamic system implies a view in which the composer draws trajectories or orbits using the elements of each set [Manzolli, 1991]. Nonlinear iterative mappings are associated with interface controls. In the next page two examples of nonlinear iterative mappings with their resulting musical pieces are shown.The mappings may give rise to attractors, defined as geometric figures that represent the set of stationary states of a non-linear dynamic system, or simply trajectories to which the system is attracted. The relevance of this approach goes beyond music applications per se. Computer music systems that are built on the basis of a solid theory can be coherently embedded into multimedia environments. The richness and specialty of the music domain are likely to initiate new thinking and ideas, which will have an impact on areas such as knowledge representation and planning, and on the design of visual formalisms and human-computer interfaces in general. Above and bellow, Vox Populi interface is depicted, showing two nonlinear iterative mappings with their resulting musical pieces. References [Manzolli, 1991] J. Manzolli.

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.

summary Most Computer Aided Architectural Design software suits the engineered aspects of design quite well but is lacking as a design medium. As far as sketching is concerned, many architects still rely on traditional media such as pen and paper and scale models. This paper presents a theory concerning design media and the application of typical media aspects in a spatial sketch program. SketchBoX is conceived as an experimental 3D version of a sketchbook. It can be used for the notation of primary forms and structures in 'architectural' space. The program consists of several transparent drawing surfaces that can be placed in relation to each other and in relation to models of design or different design contexts. Thus architects and students in architecture might be able to explore more adequately the spatial configuration of the built environment and they can comment within the models of their designs. Architectural group discussions and collaborative work can be enhanced by SketchBoX because visual annotations can be made directly in relation to a 3D model. This paper describes the consequent design considerations and expected use of the SketchBoX program.

title Integrating Databases, Objects and the World-Wide Web for Collaboration in Architectural Design
source Proceedings of the focus symposium: World Wide Web as Framework for Collaboration in conjunction with the 11th International Conference on Systems Research, Informatics and Cybernetics, The International Institute for Advanced Studies in Systems Research
summary Architectural design requires specialized vertical knowledge that goes beyond the sharing of marks on paper or the multi-casting of video images. This paper briefly surveys the state-ofthe- art in groupware and outlines the need for vertical and integrated support of synchronous and asynchronous design collaboration. The paper also describes a software prototype (WebOutliner) under development that uses a three-tier persistent object-oriented, web-based technology for a richer representation of hierarchical architectural artifacts using Apple’s WebObjects technology. The prototype contributes to earlier work that defined a framework for a shared workspace consisting of Participants, Tasks, Proposals, and Artifacts. These four elements have been found through observation and analysis to be adequate representations of the essential components of collaborative architectural design. These components are also hierarchical which allows users to filter information, copy completed solutions to other parts of the program, analyze and compare design parameters and aggregate hierarchical amounts. Given its object orientation, the represented artifacts have built-in data and methods that allow them to respond to user actions and manage their own sub-artifacts. In addition, the prototype integrates this technology with Java tools for ubiquitous synchronous web-based access. The prototype uses architectural programming (defining the spatial program of a building) and early conceptual design as examples of seamlessly integrated groupware applications.

source Media and Design Process [ACADIA ‘99 / ISBN 1-880250-08-X] Salt Lake City 29-31 October 1999, pp. 126-137
summary Collaboration is common in design, yet relatively little is known about the cognitive reasoning processes that occur during collaboration. This paper discusses collaborative design, emphasizing the elaboration and transformations of the problem search space, and the roles that unstructured verbal communication and graphic communication can play in these processes. The paper discusses a prototype system called the Immersive Discussion Tool (IDT) that supports asynchronous design. IDT allows collaborators to mark-up 3-D models over the Internet using a variety of tools, including diagrammatic marks, dynamic simulations and text annotations. IDT relies on VRML to view the models, with an extensive Java-based interface on the backend powering the interactive construction and playback of graphical annotations, the management of threaded discussions, and the management of file input/output. The development of this tool has revealed the difficulty of constructing complex marks in a virtual 3-D space, and the initial implementation of IDT suggests several strategies for solving these problems.

title APPLICATION OF SPATIAL DESIGN ABILITY IN A POSTGRADUATE COURSE
source Full-scale Modeling and the Simulation of Light [Proceedings of the 7th European Full-scale Modeling Association Conference / ISBN 3-85437-167-5] Florence (Italy) 18-20 February 1999, pp. 75-82
summary Spatial Design Ability (SDA) has been defined by the author (1983) as the capacity to anticipate the effects (psychological impressions) that architectural spaces or its components produce in observers or users. This concept, which requires the evaluation of spaces by the people that uses it, was proposed as a guideline to a Masters Degree Course in Architectural Design at the Universidad Autonoma de Aguascalientes in Mexico. The theory and the exercises required for the experience needed a model that could simulate spaces in terms of all the variables involved. Full-scale modeling as has been tested in previous research, offered the most effective mean to experiment with space. A simple, primitive model was designed and built: an articulated ceiling that allows variation in height and shape, and a series of wooden panels for the walls and structure. Several exercises were carried out, mainly to experience cause -effect relationships between space and the psychological impressions they produce. Students researched into spatial taxonomy, intentional sequences of space and spatial character. Results showed that students achieved the expected anticipation of space and that full-scale modeling, even with a simple model, proved to be an effective tool for this purpose. The low cost of the model and the short time it took to be built, opens an important possibility for Institutions involved in architectural studies, both as a research and as a learning tool.

summary Introduction: virtual reality in architecture Virtual Reality (VR) is an emergent computer technology for full 3D-simulations, which has a natural application in the architectural work, due that activity involves the complete definition of buildings prior to its construction. Although the profession has a long tradition and expertise in the use of 2D-plans for the design of buildings, the increasing complexity of projects and social participation requires better media of representation. However, the technological promise of Virtual Reality involves many sophisticated software and hardware developments. It is based on techniques of 3D-modelling currently incorporated in the majority of drawing software used in architecture, and also there are several tools for rendering, animation and panoramic views, which provide visual realism. But other capabilities like interactivity and sense of immersion are still complex, expensive and under research. These require stereoscopic helmets, 3D pointers and trackers with complicated configurations and uncomfortable use. Most advanced installations of Virtual-Reality like CAVEs involve much hardware, building space and restrictions for users. Nevertheless, diverse developers are working in Virtual-Reality user-friendly techniques and there are many initial experiences of architectural walk-throughs showing advantages in the communication and development of designs. Then we may expect an increasing use of Virtual Reality in architecture.

title CAD Interfaces to the ARROW Manufactured Product Server
source Proceedings of the Eighth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-8536-5] Atlanta, 7-8 June 1999, pp. 1-11
summary The UK national project ARROW (Advanced Reusable Reliable Objects Warehouse) provides an Internet based framework through which it is possible to identify any of a range of manufactured products meeting specific design criteria. This open framework (based upon the IAI's IFCs) provides a mechanism for users to search for products from any participating manufacturer or supplier based both on specific attributes of a product or on any of the textual descriptions of the product. The service returns the closest matching products and allows the user to navigate to related information including manufacturer, suppliers, CAD details, VR displays, installation instructions, certificates, health and safety information, promotional information, costings, etc. ARROW also provides a toolkit to enable manufacturers and suppliers to more easily map and publish their information in the format utilised by the ARROW system. As part of the ARROW project we have examined the ability to interface from a design tool through to ARROW to automatically retrieve information required by the tool. This paper describes the API developed to allow CAD and simulation tools to communicate directly with ARROW and identify appropriate manufactured information. The demonstration system enables CAD systems to identify the closest matching manufactured product to a designed product and replacing the designed product with the details supplied by the manufacturer for the manufactured product as well as pulling through product attributes utilised by the design application. This paper provides a description of the ARROW framework and issues faced in providing information based upon standards as well as containing information not currently modelled in public standards. The paper looks at issues of enabling manufacturers and suppliers to move from their current world-view of product information to a more data-rich and user accessible information repository (even though this enables a uniform comparison across a range of manufacturer's products). Finally the paper comments on the likely way forward for ARROW like systems in providing quality information to end users.

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

title An approach for the interoperation of web-distributed applications with a design model
source Automation in Construction 8 (3) (1999) pp. 291-303
summary This paper defines the data and inference requirements for the integration of analysis applications with a product model described by a CAD/CAE application. Application input conditions often require sets of complex data that may be considered views of a product model database. We introduce a method that is compatible with the STEP and PLIB product description standards to define an intermediate model that selects, extracts, and validates views of information from a product model to serve as input for an engineering CAD/CAE application. The intermediate model framework was built and tested in a software prototype, the Internet Broker for Engineering Services (IBES). The first research case for IBES integrates applications that specify certain components, for example pumps and valves, with a CAD/CAE application. This paper therefore explores a sub-set of the general problem of integrating product data semantics between various engineering applications. The IBES integration method provides support for a general set of services that effectively assist interpretation and validate information from a product model for an engineering purpose. Such methods can enable application interoperation for the automation of typical engineering tasks, such as component specification and procurement.

source Proceedings of the Eighth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-8536-5] Atlanta, 7-8 June 1999, 398 p.
summary This is the eight CAADfutures Conference. Each of these bi-annual conferences identifies the state of the art in computer application in architecture. Together, the series provides a good record of the evolving state of research in this area over the last fourteen years. Early conferences, for example, addressed project work, either for real construction or done in academic studios, that approached the teaching or use of CAD tools in innovative ways. By the early 1990s, such project-based examples of CAD use disappeared from the conferences, as this area was no longer considered a research contribution. Computer-based design has become a basic way of doing business. This conference is marked by a similar evolutionary change. More papers were submitted about Web- based applications than about any other area. Rather than having multiple sessions on Web-based applications and communications, we instead came to the conclusion that the Web now is an integral part of digital computing, as are CAD applications. Using the conference as a sample, Web-based projects have been integrated into most research areas. This does not mean that the application of the Web is not a research area, but rather that the Web itself is an integral tool in almost all areas of CAAD research.

summary The use of evolutionary algorithms to optimise designs is now well known, and well understood. The literature is overflowing with examples of designs that bear the hallmark of evolutionary optimisation: bridges, cranes, electricity pylons, electric motors, engine blocks, flywheels, satellite booms -the list is extensive and evergrowing. But although the optimisation of engineering designs is perhaps the most practical and commercially beneficial form of evolutionary design for industry, such applications do not take advantage of the full potential of evolutionary design. Current research is now exploring how the related areas of evolutionary design such as evolutionary art, music and the evolution of artificial life can aid in the creation of new designs. By employing techniques from these fields, researchers are now moving away from straight optimisation, and are beginning to experiment with explorative approaches. Instead of using evolution as an optimiser, evolution is now beginning to be seen as an aid to creativity -providing new forms, new structures and even new concepts for designers.

source Proceedings of the Eighth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-8536-5] Atlanta, 7-8 June 1999, pp. 291-308
summary In studying the phenomenon of design we use models to envision mechanisms by which computers might support design. In one such model we understand design as guided movement through a space of possibilities. Design space explorers embody this model as mixed-initiative environments in which designers engage in exploration via human computer interaction. Constraint resolution provides a formal framework for interaction in design space explorers. Rather than directly providing solutions to design problems, constraint resolution provides a mechanism for organizing construction. Therefore, we are less interested in the set of solutions to a constraint problem than the process by which intermediate steps are generated. Pi-resolution is one such mechanism applicable to design space explorers. It describes the solution, by recursive enumeration, of feature structure type constraints. During pi-resolution, satisfiers are constructed by the application of type constraints drawn from an inheritance hierarchy. This constructive process provides a strong model for design space exploration. The constraint solver does not do the work of the designer, but rather design efforts are situated in, and organized by, constraint resolution. Therefore, the efficiency of the recursive enumeration in finding solutions is not an issue, since non-determinism in the search is resolved by the human user as design space exploration.

title Evolutionary Design Tools for Mass-Customisation
source III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 152-156
summary This paper describes an instance of the author’s ongoing research in the field of Generative Design. The work is based on the premise that computer-aided design (CAD) should evolve beyond its current limitation of one-way interaction, and become a dynamic, intelligent, multi-user environment that encourages creativity and actively supports the evolution of individual, mass-customised designs which exhibit common features. The understanding of fundamental shape-forming processes in nature inspires us to move beyond the existing CAD paradigms and re-examine the way we can benefit from the computers in design. We can use this knowledge to create a new generation of computer-based design tools which use evolutionary search algorithms to generate create a common family of individual designs optimised according to particular criteria, while supporting our design intuition. The author explores this idea by illustrating a research project between the Hong Kong Polytechnic University and Deakin University (Australia). The project implements a multi-user oriented design tool for evolutionary design, which was tailored to produce a simple object such as door handle. The paper first gives a short historical and philosophical to the work, then describes the technical and algorithmic requirements, and implementation of the system. It concludes by describing an experiment in which the system was used on a "live" test group of people to generate individual, mass-customised designs.

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 Generative Texture Maps for Animation (artwork and paper)
source International Conference on Generative Art
summary An aperiodic planar tiling is employed as the initial structure for texture application. A generative process for texture metamorphosis is used to create variation producing two-dimensional art work intended for printed output. Two-dimensional animations demonstrate the process for producing new textures. Expanding from this preliminary test, rules for opacity and relative depth, scale and velocity of movement will be related the length of time a form is visible on screen and geometric form. These are demonstrated in a two-dimensional animation that uses pictorial depth cues such as atmospheric perspective, occlusion, vertical placement, and diminishing size. Modification of rules take into consideration two underlying philosophical assumptions: 1) the world is created by a benevolent "god" and 2) aesthetic criteria govern issues related to selection of visual forms that persist.

title A Virtual Reality User Interface for a Design Information System, CCAI: the Journal for the Integrated Study of Artificial Intelligence
source Cognitive Science and Applied Epistemology, Rijks Universiteit Gent
summary The computer is a tool, a complex artefact that is used to extend our reach. A computer system can provide several kinds of services, but against these services stands a supplementary task that the user must deal with: the communication with the computer system. We argued that Virtual Reality (VR) can fundamentally improve the user interface by rendering on the common experiential skills of all users. We present the theoretical basis for this, referring to Donald Norman's theory. We show that VR provides at least theoretically, the means to take a big step in the direction of an ideal user interface. As an example of a innovative application of VR in user interface design, we presented the VR-DIS system; an interdisciplinary design system for the building and construction industry. We discuss the issues underlying the design of its VR interface.

title Knowledge Structures of Episodic Memory in Architectural Design: An Example of Protocol Analysis

summary The Protocol Analysis of the design process is a very recent and very promising research field. It is believed that good application-oriented developments are possible mainly in the tutorial field (ITS). The research conducted up to now has primarily dealt with the study of the design process. On the contrary, we propose an investigation experiment on the knowledge structures relative to the use of the episodic memory in the architectural design. The proposed experiment concerns the monitoring of the cognitive processes utilised by tutors and students in a brief, but yet complete design session. The results have lead to a synthetic model (computational model) of the adopted knowledge structures, and to a complete index system oriented and organised according to semantic fields. The application of the synthetic model to the design process analysis of students and tutors enabled the definition of the different utilisation strategies of episodic memory to be defined. The results obtained will make up the structure of a tutorial program for the architectural design.
