title	Visual Communication in Urban Planning and Urban Design
source	Working Paper 2; Centre for Advanced Spatial Analysis Working Papers; London; June 1998
summary	This Case Study documents the current status of visual communication in urban design and planning. Visual communication is examined through discussion of standalone and network media, specifically concentrating on visualisation on the World Wide Web (WWW). First, we examine the use of Solid and Geometric Modelling for visualising urban planning and urban design. This report documents and compares examples of the use of Virtual Reality Modelling Language (VRML) and proprietary WWW based Virtual Reality modelling software. Examples include the modelling of Bath and Glasgow using both VRML 1.0 and 2.0. The use of Virtual Worlds and their role in visualising urban form within multi-user environments is reviewed. The use of Virtual Worlds is developed into a study of the possibilities and limitations of Virtual Internet Design Arena's (ViDA's), an initiative undertaken at the Centre for Advanced Spatial Analysis, University College London. The use of Virtual Worlds and their development towards ViDA's is seen as one of the most important developments in visual communication for urban planning and urban design since the development plan. Secondly, the role of photorealistic media in the process of communicating plans is examined. The process of creating photorealistic media is documented, and examples of the Virtual Streetscape and Wired Whitehall Virtual Urban Interface System are provided. The conclusion is that, although the use of photo-realistic media on the WWW provides a way to visually communicate planning information, its use is limited. The merging of photorealistic media and solid geometric modelling in the creation of Augmented Reality is reviewed. Augmented Reality is seen to provide an important step forward in the ability quickly and easily to visualise urban planning and urban design information. Third, the role of visual communication of planning data through GIS is examined in terms of desktop, three dimensional, and Internet based GIS. The evolution to Internet GIS is seen as a critical component in the development of virtual cities that will allow urban planners and urban designers to visualise and model the complexity of the built environment in networked virtual reality. Finally, a viewpoint is put forward of the Virtual City, linking Internet GIS with photorealistic multi-user Virtual Worlds. At present there are constraints on how far virtual cities can be developed, but a view is provided on how these networked virtual worlds are developing to aid visual communication in urban planning and urban design.

title	A suite of prototype CAD tools to support early phases of architectural design
source	Automation in Construction 7 (6) (1998) pp. 449-464
summary	A suite of prototype CAD (computer-aided design) tools has been developed as part of an educational experiment in which an architectural design studio course was combined with a computer science graduate course on architectural CAD to study the collaboration between architects and their clients in a computer-based environment. The suite of tools is based on formalized abstractions inspired by lessons learned in the VLSI (very large-scale integrated circuit) CAD revolution of the 1980s. It encourages a step-by-step transformation of a building program, first into symbolic representations that can be checked and evaluated with automated programs, and eventually into simple but consistent 3-D (three-dimensional) geometry that can be inspected with an interactive walk-through visualization program.

title	Neutral intelligent CAD communication: information exchange in construction based upon a minimal schema
source	KTH Stockholm
summary	An improved information exchange is frequently proposed as one solution to the inefficiency problems which the construction industry is suffering from today. Such an improvement is very dependent of the use of information technology, IT. To enable an advanced use of IT, there is a need for integrated project communications frameworks and integrated industry wide information. This thesis discusses how product models can be used to improve the information exchange from design to construction. Today there are several approaches to product modelling. Some researchers propose very detailed models whereas others propose generic models with fewer concepts. In this area there is a close connection between research and standardisation, which is carried out by organisations such as the ISO STEP committee and the International Alliance for Interoperability. To get acceptance for a standard proposal, it has to be accepted by both users and standardisation bodies. Thus this research, in addition to the technical requirements on information content and structure, also discusses success factors for standardisation, implementation and usage. In order to define important requirements on a product model for information exchange between design and construction, current research, development and standardisation in the field of product modelling was studied. This thesis advocates a minimal approach in the number of concepts used in a product model, in combination with an external building element classification, following national industry practice. The minimal NICC schema, developed during this research, was tested in a prototype and test study. Three applications were tested: PreFacto (planning tool), Microsoft Project (time scheduling tool) and Calc3(cost estimation tool). From the CAD-system MCAD, NICC files with the building objects were created and transferred into a relational database from which the three applications received their specific input files. The results of the evaluation of the NICC schema and the test study demonstrated that a product model based on few concepts can manage the required information exchange.

summary	The architectural objects and their site are an indivisible part of the concrete culture of a place.in order to achieve the protection of the Cultural Property, the indispensable previous step is the fulfilment of an inventory. If a good inventory is not available, serious tasks of public awareness could not be carried out, nor could be adopted policies or specific safeguard projects. Besides, neither criteria nor protective measurements in the plans of urban or regional development could be incorporated. Finally, we could not discuss with the sufficient scientific support. San Juan has climatic features typical of and regions with high seismic risk, scarce hydric resources, landscape diversity and singular vegetation. This favoured the cultivation of vineyards as well as the construction of important industrial buildings. In this sense, the Architecture of the Vine Production and Wine - making gave rise to establishments (buildings and sites), whose architectural characteristics, in a holistic consideration, are part of the Provincial Architectural Patrimony. A relational database structured by fields related to different levels of information was designed so as to fulfil this inventory. The data processing application used enables to search and ask for information by means of an easy access interface with the following possibilities :expansion, versatility in the design of visualization-printing plugs and readiness to migrate to other formats.

title	Shaping Structures
source	New York: John Wiley and Sons
summary	In Shaping Structures, an engineer and an architect, both longtime teachers of structures at major American universities, collaborate to present an inspired synthesis of the creative and the technical, explicating both the principles of statics and their application to the fascinating task of finding good form for structures. This richly visual volume features: * An easily understood development of the fundamentals of statics * Step-by-step demonstrations, using both numerical and graphical techniques, of simple yet powerful methods for finding form and forces for arched structures, suspended structures, cable-stayed structures, and highly efficient trusses * 120 photographs and more than 300 crisp drawings that illustrate and explain the magnificent structural triumphs of master architects and engineers -including Gustave Eiffel's famous tower, Robert Maillart's soaring bridges, Pier Luigi Nervi's landmark Turin Exhibition Hall, and many others * Calculations in both SI metric and conventional units throughout the book Requiring only the most rudimentary mathematical background yet accurate and fully functional, Shaping Structures provides an inviting point of entry to the study of structural design for engineering and architecture students -proving that the science of statics doesn't have to be lifeless, simplistic, or dull.

title	Archetypes as Precedent of Virtual Architectures
source	II Seminario Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings / ISBN 978-97190-0-X] Mar del Plata (Argentina) 9-11 september 1998, pp. 32-35
summary	Archetypes are psychological concepts described by the renowned Swiss psychologist Cari Jung. It is possible identify archetypal forms in eminent buildings of different regions and ages, recognizing archetypes as a multi-cultural liaison for various architectures. These concepts function as basic precedents of spatial design in different geographical and historical contexts. The emerging digital culture is establishing a plethora of virtual environments, through web-pages of the Internet, global TV, multimedia CD, video games and immersive devices. These virtual environments offer electronic activities and tools for architectural practice. In both senses, virtual architectures conforms to the visual and spatial characteristics of technologies. Thus, electronic capabilities establish digital habitats and references to contemporary architecture. Since virtual architectures are immaterial constructions, perceptual properties guide the spatial and formal design. In that sense, archetypes allow a basic vocabulary for the design of virtual architectures, linking them to cultural history and giving them a human orientation.

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	AutoPave: towards an automated paving system for asphalt pavement compaction operations
source	Automation in Construction 8 (2) (1998) pp. 165-180
summary	Asphalt pavement density from roller compaction is a crucial factor in ensuring satisfactory pavement performance. Proper and uniform compaction of the pavement mat is essential in achieving the desired final compacted density. There is a necessity to investigate existing pavement construction practices, and provide more cost-effective modifications to the current scenario. Automation of the paving operation can increase the efficiency and quality of the operation, lead to reductions in overall project costs and time, and enhance pavement life. A system can be developed through algorithmic planning and real-time guidance strategies, and the development of a semi-automated path-planning and real-time guidance system that aims towards automating the paving operation. This system accepts relevant paving project inputs, generates appropriate path plans for the compactor, performs a graphical visualization of the generated path plan, and offers real-time guidance capabilities using Global Positioning Systems (GPS) technology. This system, named AUTOPAVE (v1.0), was developed in Microsoft Visual Basic™ programming language and offers a user-friendly and interactive graphical interface. The proposed new system will incorporate state-of-the-art GPS technology to standardize paving operations that are more amenable to rigorous quality control, and can result in considerable reductions in cost and time involved in asphalt pavement construction projects. This system was tested on several actual paving projects, and many operational issues related to the functioning of the system were successfully overcome.

title	SHARED SPACE’ AND ‘PUBLIC SPACE’ DIALECTICS IN COLLABORATIVE ARCHITECTURAL DESIGN.
source	Proceedings of Collaborative Decision-Support Systems Focus Symposium, 30th July, 2002; under the auspices of InterSymp-2002, 14° International Conference on Systems Research, Informatics and Cybernetics, 2002, Baden-Baden, pg. 27-44.
summary	The present paper describes on-going research on Collaborative Design. The proposed model, the resulting system and its implementation refer mainly to architectural and building design in the modes and forms in which it is carried on in advanced design firms. The model may actually be used effectively also in other environments. The research simultaneously pursues an integrated model of the: a) structure of the networked architectural design process (operators, activities, phases and resources); b) required knowledge (distributed and functional to the operators and the process phases). The article focuses on the first aspect of the model: the relationship that exists among the various ‘actors’ in the design process (according to the STEP-ISO definition, Wix, 1997) during the various stages of its development (McKinney and Fischer, 1998). In Collaborative Design support systems this aspect touches on a number of different problems: database structure, homogeneity of the knowledge bases, the creation of knowledge bases (Galle, 1995), the representation of the IT datum (Carrara et al., 1994; Pohl and Myers, 1994; Papamichael et al., 1996; Rosenmann and Gero, 1996; Eastman et al., 1997; Eastman, 1998; Kim, et al., 1997; Kavakli, 2001). Decision-making support and the relationship between ‘private’ design space (involving the decisions of the individual design team) and the ‘shared’ design space (involving the decisions of all the design teams, Zang and Norman, 1994) are the specific topic of the present article. Decisions taken in the ‘private design space’ of the design team or ‘actor’ are closely related to the type of support that can be provided by a Collaborative Design system: automatic checks performed by activating procedures and methods, reporting of 'local' conflicts, methods and knowledge for the resolution of ‘local’ conflicts, creation of new IT objects/ building components, who the objects must refer to (the ‘owner’), 'situated' aspects (Gero and Reffat, 2001) of the IT objects/building components. Decisions taken in the ‘shared design space’ involve aspects that are typical of networked design and that are partially present in the ‘private’ design space. Cross-checking, reporting of ‘global’ conflicts to all those concerned, even those who are unaware they are concerned, methods for their resolution, the modification of data structure and interface according to the actors interacting with it and the design phase, the definition of a 'dominus' for every IT object (i.e. the decision-maker, according to the design phase and the creation of the object). All this is made possible both by the model for representing the building (Carrara and Fioravanti, 2001), and by the type of IT representation of the individual building components, using the methods and techniques of Knowledge Engineering through a structured set of Knowledge Bases, Inference Engines and Databases. The aim is to develop suitable tools for supporting integrated Process/Product design activity by means of a effective and innovative representation of building entities (technical components, constraints, methods) in order to manage and resolve conflicts generated during the design activity.

summary	A cellular automaton that includes some principles from quantum theory is considered. The automaton generates forms of an aesthetic nature. At every time step, a form grows with a single cell. This cell is selected with a selection probability that is determined by an amplitude. If the algorithm is run with selection of the cell of maximal amplitude at every time step, a type of form results that is called 'platonic'. Such forms typically have higher aesthetic complexity than their non-platonic counterparts. The case of selection probabilities determined by squares of amplitudes has a strong analogy with quantum theory. This analogy is elaborated by consideration of forms that have mutual correlations. These correlations can be of a classical nature, of a quantum mechanical type, or of a type that is termed 'super-correlation'.

title	Cumulative Index of CAAD: Current Status and Future Directions
source	International Journal of Architectural Computing vol. 1 - no. 2
summary	This article discusses the Cumulative Index of CAAD (CUMINCAD.SciX.net) - a digital library set up in 1998 serving the CAAD-community as an important source of scientific information. During the first stage, the metadata of CAAD-related conference proceedings were compiled and published on-line, including all abstracts and approximately 50% of the full-texts. In a subsequent step a Citation Index was created. Currently, theses and dissertations are being added to the library. Furthermore, a hierarchical topic structure was developed for automated classification of publications in the future, with topics being defined by keywords and characteristic papers.The next version of CUMINCAD, expected to be released later this year, will also feature a discussion forum, an event calendar, an option for commenting on and ranking publications as well as creating an on-line personal bibliographic review. CUMINCAD is a unique digital library in the field of CAAD serving a growing user-community. Younger doctoral degree students and junior researchers will benefit most from this edited, structured collection freely available via Internet.

title	COMPUTER AIDED GENERATION OF ARCHITECTURAL TYPOLOGIES
source	Proceedings of the Fourth International Conference of Mathematics & Design, Special Edition of the Journal of Mathematics & Design, Volume 4, No.1, pp. 73-82.
summary	The work we present may be considered as the consolidation of a methodology that was already outlined in the paper presented in the second M&D congress held in San Sebastian (1998). We establish that, in architectural design, the computer is only used in the last step in order to achieve the traditional Euclidean design in a more precise and comfortable way and to improve the quality of the handmade designs. Our proposal consists in modifying the process from the very beginning of the creative act. That is, when the design conception is born. If we want to obtain the maximum benefit of the computer possibilities, we ought to support this conception by means of a language tuned with the mentioned tool. Due to the fact that the internal language used by the computer for producing graphics is mathematical, we must incorporate, in some way, this language in the codification of the creative process. In accordance with this setting, we propose a mathematical grammar for the design based on the construction of modulated standard mathematical functions. This grammar is developed independently from the graphical software and it is specified only when a particular computer program for the effective generation on the graphical objects is selected.

title	Speech-Driven Computer-Aided Design - Innovation in Human-Computer Interaction
doi	https://doi.org/10.52842/conf.caadria.1998.309

summary	The use of computers in architectural design has shifted from what initially was a very numerical approach into a graphical way and thus into a designerly way of working. Through the extensive use of WIMPs CAAD packages today are more or less user-friendly. In the meantime the ever increasing functionality of those packages inflate the number of commands, actions, options and choices which have to be activated with the mouse in order to generate a structured drawing. As a result packages become rather cumbersome to handle. In this research we have explored a new medium, namely speech, to tell the machine what to do. With software for speech recognition and making use of a head-mounted microphone we have built a far more user-friendly way of handling a CAD package. Grids, snap, ortho, layers, settings and other commands that can be used in combination with mouse actions are activated and deactivated by voice command. We are convinced that this is a step further towards a more easy and natural way of using computers while designing and certainly a way for speeding up the modeling of real architecture. The experiment has been conducted for AutoCAD with the software for speech recognition by Lernout & Hauspie. This new way of working is not limited to architecture and the principle can be used right now for any other package, provided it has a programming interface.

title	Model of Design Parts and its Use to the Design Team
doi	https://doi.org/10.52842/conf.caadria.1998.233
source	CAADRIA ‘98 [Proceedings of The Third Conference on Computer Aided Architectural Design Research in Asia / ISBN 4-907662-009] Osaka (Japan) 22-24 April 1998, pp. 233-242
summary	This paper discusses the impact of the choice of representation on the final result in design and construction projects. Representation is an integrated part of the design process used by architects as a communication tool to help them present a concept to their clients and other consultants. The representation choice, in addition, reflects the professional’s perception of the design process and the architectural artefact. Architects’ offices work with a wide range of problems - aesthetic and spatial issues, detailing, choice of materials, and systems design. The multiplicity of representations enriches the understanding of these issues. Today, the model-oriented approach in design is common among both architects and leading software producers for the construction industry. While STEP (Standard for the Exchange of Product Data) aims at developing very comprehensive product models, we examine the possibility of building up a small-scale model responding to the information needs of a design team. In our research work, we view a model of design parts as a suitable carrier of information allowing the designers to store data reflecting their accumulated and refined professional knowledge and experience. Besides, the team of architects can later easily retrieve information needed for future design reuse from the model. To reuse design solutions and learn from previous work is an essential part of the professional culture. The construction industry as a whole has been slow in implementing information technology to improve the work methods. Neither have architects’ offices used the full potential of this technology to structure information and rationalize the design process. The objective of this study is to examine whether information technology makes it possible to organize all the design information in an office archive. The proposed model of design parts relates to national standards and universal models for product data representation and exchange, such as STEP. Today, the construction sector is becoming increasingly aware of the potential of the model-oriented approach both to rationalize the design and construction process and offer designers new options to store, broaden and reuse professional knowledge. We have used the information modelling language EXPRESS to describe our concept.

summary	As in any branches of the science, the newcoming technologies play always a role in each of the related specific disciplines. The developments of Information and Communication Technology (ICT) have an important impact on architectural design and the process of the design as well as it is a part of the other technological developments. Surely these rapidly ongoing developments will influence the way of designing and the design process. What will change in the building practice by the use of this technology? How should we use this technology to reach our goals? What will be the next step in future developments? In this paper we give an overview of the use the ICT in general for architectural design and the design process and focus on the future developments. The aspect of integration (tools and partners) and the development of Decision Support Environment in the building process by means of the Artificial Intelligence (Al) technologies are mentioned.

title	Replacement and Transformation as a Key to Schematic Design Thinking - 3-D Modeling System which Supports Design Thinking
doi	https://doi.org/10.52842/conf.caadria.1998.365
source	CAADRIA ‘98 [Proceedings of The Third Conference on Computer Aided Architectural Design Research in Asia / ISBN 4-907662-009] Osaka (Japan) 22-24 April 1998, pp. 365-374
summary	This paper analyses a prototype of a 3D modeling system that can support schematic design development and begins with very abstract representation elaborates it step by step into a detailed representation. Using Mitchell's concept of a TOPDOWN system for 2D sketches as the basis, the authors proposed a design process model and a prototype that allows both bottom up additive processes in exploring the design frame and top down processes for the design refinement of each building element. Various utilities of replacing and transforming graphic objects as well as those that can control shapes and the location of those objects with construction lines have been proposed. The authors discussed possible use of the system and topics for future study by reviewing case studies.

title	Data enhancement for sharing of ship design models
source	Computer-Aided Design, Vol. 30 (12) (1998) pp. 931-941
summary	Within a shipyard, many designers each having their own design objective cooperate in a complex design situation where a variety of software tools run on differenthardware platforms. The exchange of design data models among these heterogeneous CAD systems is a difficult task because the systems involved have different datastructures optimized for their own functions. CAD geometric models are represented by different schemes such as 2D graphic entities, 3D wireframe, 3D surface model,and solid B-Rep/CSG model. A data exchange usually requires topological modifications of CAD data. This paper presents a strategy of CAD data enhancement for thepurpose of data exchange that includes topological changes of geometric models. As a practical example, a shipbuilding product model with shipbuilding features isimplemented according to the STEP methodology. Its geometric data is enhanced through a non-manifold modeler to a data set valuable to downstream applications suchas a FEM solver or a detail design system. The ACIS modeler that supports a non-manifold data structure is used for low-level geometric operations.

title	Conjoint Approaches to Developing Activity-Based Models

summary	Since the late 1950s, transportation models have played an important role in forecasting travel demand and evaluating the impacts of plans and policies. Planners use transportation models to learn about the behavior of transport systems. Over the past decades, the development of particular modeling approaches has closely followed planning needs, which in turn are closely related to dominant policy issues. The first generation of transportation models was developed during the late 1950s and early 1960s. Their purpose was to facilitate the prediction of future travel demand, such that road capacity programs could be based on predicted demand. The first generation models are commonly referred to as four-step models. These models are typically formulated and calibrated at the level of the traffic zones. Individuals are aggregated by traffic zone. Traffic is considered to be the result of four sequential decisions: trip generation, trip distribution, modal split and traffic assignment. These decisions are modeled separately at successive stages. Although the four-step models have been widely used, even institutionalized in literally thousands of applications (Stopher, et al., 1996), the major shortcoming of these large-scale, aggregate and supply-oriented models is their lack of behavioral content.
