summary Computer based visualisation of 3D models in architecture has been possible for 20 years or more, and the software technology has steadily improved during this time so that now incredibly realistic images can be generated from any viewpoint in a model, and impressive fly through sequences can bring a model to life in ways previously not possible. Virtual reality is with us and multi-media enables us to present a finished design in increasingly seductive ways. However, these forms of output from a 3D model offer much more limited benefits during the design process and particularly on large complex models because they are so computing intensive and it often require many hours to produce just one image. Anything other than a small and relatively simple model cannot be viewed dynamically in real-time on a desktop PC of the type commonly used by architects in a design office. Until now the solution to this problem has meant investing in expensive design review hardware and software with its inherent need for trained, skilled labour. As a result, design review products are often viewed as a luxury or costly necessity.

summary The web offers both business and academic users potential benefits from on-line collaboration. Online education presents universities with a means of handling the “baby boom echo” without expanding physical campuses (Carnevale 2000). Business “extranets” allow greater coordination amongst team members on projects where the cast of players involves experts in different locations. Both involve substituting computer-mediated communications (CMC) for traditionally face-to-face communications. Over the past several years, the author has deployed several of the available CMC technologies in support of small group interaction in academic and administrative settings. These technologies include email, video conferencing, web publication, web bulletin boards, web databases, mailing lists, and hybrid web BBS/email combinations. This paper reflects on aspects of embodied human interaction and the affordances of current CMC technology, identifying opportunities for both exploitation and additional development. One important but under-supported aspect of work group behavior is workspace awareness, or peripheral monitoring. The Compadres web-based system, which was developed to support workspace awareness among distributed workgroup members, is described. These findings are relevant to those seeking to create online communities: virtual design studios, community groups, distributed governance organizations, and workgroups formed as parts of virtual offices.

title Some Phenomena of Spatial Characteristics of Cyberspace
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 "Space," which has long been an important concept in architecture (Bloomer & Moore, 1977; Mitchell, 1995, 1999), has attracted interest of researchers from various academic disciplines in recent years (Agnew, 1993; Benko & Strohmayer, 1996; Chang, 1999; Foucault, 1982; Gould, 1998). Researchers from disciplines such as anthropology, geography, sociology, philosophy, and linguistics regard it as the basis of the discussion of various theories in social sciences and humanities (Chen, 1999). On the other hand, since the invention of Internet, Internet users have been experiencing a new and magic "world." According to the definitions in traditional architecture theories, "space" is generated whenever people define a finite void by some physical elements (Zevi, 1985). However, although Internet is a virtual, immense, invisible and intangible world, navigating in it, we can still sense the very presence of ourselves and others in a wonderland. This sense could be testified by our naming of Internet as Cyberspace -- an exotic kind of space. Therefore, as people nowadays rely more and more on the Internet in their daily life, and as more and more architectural scholars and designers begin to invest their efforts in the design of virtual places online (e.g., Maher, 1999; Li & Maher, 2000), we cannot help but ask whether there are indeed sensible spaces in Internet. And if yes, these spaces exist in terms of what forms and created by what ways?To join the current interdisciplinary discussion on the issue of space, and to obtain new definition as well as insightful understanding of "space", this study explores the spatial phenomena in Internet. We hope that our findings would ultimately be also useful for contemporary architectural designers and scholars in their designs in the real world.As a preliminary exploration, the main objective of this study is to discover the elements involved in the creation/construction of Internet spaces and to examine the relationship between human participants and Internet spaces. In addition, this study also attempts to investigate whether participants from different academic disciplines define or experience Internet spaces in different ways, and to find what spatial elements of Internet they emphasize the most.In order to achieve a more comprehensive understanding of the spatial phenomena in Internet and to overcome the subjectivity of the members of the research team, the research design of this study was divided into two stages. At the first stage, we conducted literature review to study existing theories of space (which are based on observations and investigations of the physical world). At the second stage of this study, we recruited 8 Internet regular users to approach this topic from different point of views, and to see whether people with different academic training would define and experience Internet spaces differently.The results of this study reveal that the relationship between human participants and Internet spaces is different from that between human participants and physical spaces. In the physical world, physical elements of space must be established first; it then begins to be regarded as a place after interaction between/among human participants or interaction between human participants and the physical environment. In contrast, in Internet, a sense of place is first created through human interactions (or activities), Internet participants then begin to sense the existence of a space. Therefore, it seems that, among the many spatial elements of Internet we found, "interaction/reciprocity" Ñ either between/among human participants or between human participants and the computer interface Ð seems to be the most crucial element.In addition, another interesting result of this study is that verbal (linguistic) elements could provoke a sense of space in a degree higher than 2D visual representation and no less than 3D visual simulations. Nevertheless, verbal and 3D visual elements seem to work in different ways in terms of cognitive behaviors: Verbal elements provoke visual imagery and other sensory perceptions by "imagining" and then excite personal experiences of space; visual elements, on the other hand, provoke and excite visual experiences of space directly by "mapping".Finally, it was found that participants with different academic training did experience and define space differently. For example, when experiencing and analyzing Internet spaces, architecture designers, the creators of the physical world, emphasize the design of circulation and orientation, while participants with linguistics training focus more on subtle language usage. Visual designers tend to analyze the graphical elements of virtual spaces based on traditional painting theories; industrial designers, on the other hand, tend to treat these spaces as industrial products, emphasizing concept of user-center and the control of the computer interface.The findings of this study seem to add new information to our understanding of virtual space. It would be interesting for future studies to investigate how this information influences architectural designers in their real-world practices in this digital age. In addition, to obtain a fuller picture of Internet space, further research is needed to study the same issue by examining more Internet participants who have no formal linguistics and graphical training.

summary This work is part of a long term research programme (Brown and Horton, 1992; Brown and Nahab, 1996; Bassanino, 1999) in which tests and studies have been carried out on various groups of people to investigate their reaction to, and interpretation of different forms of architectural representation. In the work described here a range of architectural schemes were presented using particular representational techniques and media. An experiment was then undertaken on two different groups; architects and lay people. They were presented with a number of schemes displayed using the various techniques and media. The responses are summarised and some comments are made on the effect of computers on perceiving architecture and on communicating architectural ideas arising from an analysis of the responses.

summary Throughout history, architecture has transposed contributions bound to structuralist focus or to musical composition. This is from linguistic and music respectively. New visualization systems show the possibility to give transpositions a new meaning, form the potentialities of hypermedia; locking for new projects parameters. This papers will show experimental workshop results developed within CI+D 2000 “New speeches and design process”. They study links and explore our work interrelating word – music and image. These processes are developed by people coming from literature, visual arts, music, and architecture areas. Lastly, the first results will be shown. Since parameters were transposed from music, by using NURBS forms, space prefiguration is tried out. [Full paper in Spanish]

summary Most students commencing their university studies in architecture must confront and master two new modes of thought. The first, widely known as reflection-in-action, is a continuous cycle of self-criticism and creation that produces both learning and improved work. The second, which we call here design making, is a process which considers building construction as an integral part of architectural designing. Beginning students in Australia tend to do neither very well; their largely analytic secondary education leaves the majority ill-prepared for these new forms of learning and working. Computers have both complicated and offered opportunities to improve this situation. An increasing number of entering students have significant computing skill, yet university architecture programs do little in developing such skill into sound and extensible knowledge. Computing offers new ways to engage both reflection-in-action and design making. The collaboration between two Schools in Australia described in detail here pools computer-based learning resources to provide a wider scope for the education in each institution, which we capture in the phrase: Learn to use computers in architecture (not use computers to learn architecture). The two shared learning resources are Form Making Games (Adelaide University), aimed at reflection-in-action and The Construction Primer (Deakin University and Victoria University of Wellington), aimed at design making. Through contributing to and customising the resources themselves, students learn how designing and computing relate. This paper outlines the collaborative project in detail and locates the initiative at a time when the computer seems to have become less self-consciously assimilated within the wider architectural program.

title ACADIA 2000: Eternity, Infinity and Virtuality in Architecture
doi https://doi.org/10.52842/conf.acadia.2000

summary Eternity, time without end, infinity, space without limits and virtuality, perception without constraints; provide the conceptual framework in which ACADIA 2000 is conceived. It is in human nature to fill what is empty and to empty what is full. Today, thanks to the power of computer processing we can also make small what is too big, make big what is too small, make fast what is too slow, make slow what is too fast, make real what does not exist, and make our reality omni-present at global scale. These are capabilities for which we have no precedents. What we make of them is our privilege and responsibility. Information about a building flows past our keyboards and on to other people. Although we, as architects, add to the information, it originated before us and will go beyond our touch in time, space and understanding. A building description acquires a life of its own that may surpass our own lives as it is stored, transferred, transformed, and reused by unknown intellects, both human and artificial, and in unknown processes. Our actions right now have unforeseen effects. Digital media blurs the boundaries of space, time and our perception of reality. ACADIA 2000 explores the theme of time, space and perception in relation to the information and knowledge that describes architecture. Our invitation to those who are finding ways to apply computer processing power in architecture received overwhelming response, generating paper submissions from five continents. A selected group of reviewers recommended the publication of 24 original full papers out of 42 submitted and 13 short papers out of 30 submitted. Forty-two projects were submitted to the Digital Media Exhibit and 12 were accepted for publication. The papers cover subjects in design knowledge, design process, design representation, design communication, and design education. Fundamental and applied research has been carefully articulated, resulting in developments that may have an important impact on the way we practice and teach architecture in the future.

title A CAD-based decision support system for the design stage of a construction project
source Timmermans, Harry (Ed.), Fifth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Nijkerk, the Netherlands)
summary Decisions made during the design process are multi-dimensional, combining together factors which range from the highly subjective to the perfectly objective. These decisions are made by many, often non co-located, actors belonging to different disciplines. Moreover, there is a high risk for misunderstandings, inappropriate changes, and decisions, which are not notified to all interested parties. The ADS project (Advanced Decision Support for Construction Design) builds on the results of the earlier COMMIT project to provide an information management system, which addresses these problems. It defines mechanisms to handle the proactive management of information to support decision-making in collaborative projects. Different aspects of the COMMIT system have already been widely published, and the team is now applying the results in the context of construction design. These are referenced in the present paper, which gives an overview of the results of the COMMIT project and discusses some of the issue involved in applying them to the design process in conjunction with an advanced CAD tool.

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

title Virtual Reality and the Future of Publishing Archaeological Excavations: the multimedia publication of the prehistoric settlement on Tsoungiza at Ancient Nemea
source New York: The Metropolitan Museum of Art
summary The Nemea Valley Archaeological Project is a study of settlement and land use in a regional valley system in Greece extending from the Upper Paleolithic until the present. Active field research was conducted by four teams between 1981 and 1990. The first component was a regional archaeological survey. Second, and closely related to the first, was a social anthropological study of modern settlement and land use. Next was a team assigned to excavate the succession of prehistoric settlements of Ancient Nemea on Tsoungiza. Last, historical ecologists, a palynologist, and a geologist formed the environmental component of the research. As a result of advances in electronic publishing, plans for the final publication of the Nemea Valley Archaeological Project have evolved. Complete publication of the excavation of the prehistoric settlements of Ancient Nemea on Tsoungiza will appear in an interactive multimedia format on CD/DVD in Fall 2000. This project is planned to be the first electronic publication of the American School of Classical Studies at Athens. We have chosen to publish in electronic format because it will meet the needs and interests of a wider audience, including avocational archaeologists, advanced high school and college students, graduate students, and professional archaeologists. The multimedia format on CD/DVD will permit the inclusion of text, databases, color and black-and-white images, two and three-dimensional graphics, and videos. This publication is being developed in cooperation with Learning Sites, Inc., which specializes in interactive three-dimensional reconstructions of ancient worlds http://www.learningsites.com. The Nemea Valley Archaeological Project is particularly well prepared for the shift towards electronic publishing because the project's field records were designed for and entered in computer databases from the inception of the project. Attention to recording precise locational information for all excavated objects enables us to place reconstructions of objects in their reconstructed architectural settings. Three-dimensional images of architectural remains and associated features will appear both as excavated and as reconstructed. Viewers will be able to navigate these images through the use of virtual reality. Viewers will also be able to reference all original drawings, photographs, and descriptions of the reconstructed architecture and objects. In this way a large audience will be able to view architectural remains, artifacts, and information that are otherwise inaccessible.

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 The Synthetic Dialect And Cybernetic Architectural Form
source Emerging Technologies and Design: The Intersection of Design and Technology. Proceedings of the 2000 ACSA Technology Conference, MIT Cambridge (Massachusetts) 4-7 July 2000, pp.117-122
summary Recently a significant philosophical split has appeared within the discipline of architecture. The split exists because the architectural profession is adopting a new digital framework, from which it can challenge the traditional cultural and technical pursuits of the discipline. This paper is about this split within the profession and about using it to develop challenging contemporary architectural forms that work to fill the ‘gap.’

So where does the split come from? Our discipline and its associated discourses have over time been informed by the technologies used to construct it, design it, and mediate it, but also constrained by these things and our understandings of them. With this in mind, one can realize that it is the technologies of the time that in fact shape the philosophical positions and styles adopted by both individual designers and entire genres.

This gap isn’t an easy thing to pin down. It takes on several forms all of which seem to stem from the same source, that being the influence of information constructs on space. If anything this paper aims to uncover the differences and similarities of these constructs, and use them to understand the digital genre that presently surrounds us.

title Object-Oriented Application Development in CAD
source Technical Report 48-01-01. Pittsburgh, PA: Carnegie Mellon University, Institute of Complex Engineered Systems
summary This report describes a graduate interdisciplinary course offered to students in the graduate program of the School of Architecture at Carnegie Mellon and related departments in fall 2000. The motivation was the realization that when commercial CAD (Computer-Aided Design) systems recently switched from procedural application programming languages to object-oriented ones, third-party application must undergo a significant cognitive retooling"; i. e. they must know more than the syntax and semantics of the new programming language to be used and must be able to employ appropriate software development strategies that are appropriate for the new paradigm. especially with respect to the importance of modeling, a distinguishing characteristic of object-oriented programming. The goal of the course was (a) to introduce and test strategies of object-oriented application development in general and in the context of MicroStation, a state-of-the-art commercial CAD package; (b) to develop-as a course team project-an interesting application that gives students practice with these strategies and team work; and (c) to document our approach and findings so that others can learn from them. The strategies introduced were the use-case approach of Jacobson et al. and the complementary object-modeling tools of Rumbaugh that were recently integrated into the Unified Modeling Language UML. The software platform supporting the course comprised MicroStation, JMDL (a superset of Java) and ProjectBank on the CAD side and RationalRose on the modeling side. The application developed by students in the course supports the generation of drawings for remodeling projects from a set of dgn files describing the existing state of the building to be remodeled. The course was supported by a grant and in-kind contributions from Bentley with matching funds from the Pennsylvania Infrastructure Technology Alliance (PITA)."

title WebOutliner: A Web-Based Tool for Collaborative Space Programming and Design
doi https://doi.org/10.52842/conf.acadia.2000.195
source Eternity, Infinity and Virtuality in Architecture [Proceedings of the 22nd Annual Conference of the Association for Computer-Aided Design in Architecture / 1-880250-09-8] Washington D.C. 19-22 October 2000, pp. 195-201
summary This paper discusses a web-based tool that allows members of a design team to collaboratively specify a hierarchical spatial program for an architectural project. 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. Given that these components are hierarchical allows users to filter information, analyze and compare design parameters and aggregate hierarchical amounts in realtime. Furthermore, the software goes beyond outlining functions to support synchronous collaborative design by linking each item in the spatial program to a detail page that allows file uploading, realtime group marking of images, and textual chat. Thus, the software offers a seamless transition from the largely asynchronous definition of an architectural program to synchronous collaboration. In addition, and in contrast to commercially available groupware, the software allows multiple collaboration sessions to run at the same time. These sessions are artifact-based in the sense that they get automatically initiated once participants visit the same architectural space in the program hierarchy. The software employs a three-tier object-oriented, web-based scheme for a richer representation of hierarchical artifacts coupled with a relational database for server-side storage. The prototype integrates this technology with Java-based tools for synchronous web-based collaboration.

title Evolutionary design systems: a conceptual framework for the creation of generative processes
source Timmermans, Harry (Ed.), Fifth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Nijkerk, the Netherlands)
summary This paper presents an conceptual framework for the construction of generative mapping processes as a basis for creating active design tools in the domain of architecture. Such generative processes are seen as key components within evolutionary systems that manipulate populations of alternative solutions in order to discover previously unexplored possibilities. Solutions are represented in two forms: as highly encoded genotypes referred to as design seeds and as decoded phenotypes referred to as design proposals. The generative process maps the design seed to the design proposal. The discussion of generative processes is in two parts. In the first part it is argued that any generative process that aims to create a wide range of solutions that differ from each other in fundamental ways must focus on a limited subcategory of possible designs. It is proposed that the endeavour to create active design tools demands that the focus be on the designer's highly personalised style, called a design-schema. The second part discusses how to uncover the essence of an architectural design-schema. In particular, it is argued that implicit and familiar aspects of buildings must be scrutinised in order to reveal the knowledge that is essential to capturing and codifying a design-schema. A range of rationalisations and conceptualisations of built form are presented with examples to illustrate possible routes of analysis. Finally, in conclusion, the possibility of discovering universal generators common to many divers generative processes are discussed.

summary The VR-DIS research programme aims at the development of a Virtual Reality – Design Information System. This is a design and decision support system for collaborative design that provides a VR interface for the interaction with both the geometric representation of a design and the non-geometric information concerning the design throughout the design process. The major part of the research programme focuses on early stages of design. The programme is carried out by a large number of researchers from a variety of disciplines in the domain of construction and architecture, including architectural design, building physics, structural design, construction management, etc.Management of design information is at the core of this design and decision support system. Much effort in the development of the system has been and still is dedicated to the underlying theory for information management and its implementation in an Application Programming Interface (API) that the various modules of the system use. The theory is based on a so-called Feature-based modelling approach and is described in the PhD thesis by [first author, 1999] and in [first author et al., 2000a]. This information modelling approach provides three major capabilities: (1) it allows for extensibility of conceptual schemas, which is used to enable a designer to define new typologies to model with; (2) it supports sharing of conceptual schemas, called type-libraries; and (3) it provides a high level of flexibility that offers the designer the opportunity to easily reuse design information and to model information constructs that are not foreseen in any existing typologies. The latter aspect involves the capability to expand information entities in a model with relationships and properties that are not typologically defined but applicable to a particular design situation only; this helps the designer to represent the actual design concepts more accurately.The functional design of the information modelling system is based on a three-layered framework. In the bottom layer, the actual design data is stored in so-called Feature Instances. The middle layer defines the typologies of these instances in so-called Feature Types. The top layer is called the meta-layer because it provides the class definitions for both the Types layer and the Instances layer; both Feature Types and Feature Instances are objects of the classes defined in the top layer. This top layer ensures that types can be defined on the fly and that instances can be created from these types, as well as expanded with non-typological properties and relationships while still conforming to the information structures laid out in the meta-layer.The VR-DIS system consists of a growing number of modules for different kinds of functionality in relation with the design task. These modules access the design information through the API that implements the meta-layer of the framework. This API has previously been implemented using an Object-Oriented Database (OODB), but this implementation had a number of disadvantages. The dependency of the OODB, a commercial software library, was considered the most problematic. Not only are licenses of the OODB library rather expensive, also the fact that this library is not common technology that can easily be shared among a wide range of applications, including existing applications, reduces its suitability for a system with the aforementioned specifications. In addition, the OODB approach required a relatively large effort to implement the desired functionality. It lacked adequate support to generate unique identifications for worldwide information sources that were understandable for human interpretation. This strongly limited the capabilities of the system to share conceptual schemas.The approach that is currently being implemented for the core of the VR-DIS system is based on eXtensible Markup Language (XML). Rather than implementing the meta-layer of the framework into classes of Feature Types and Feature Instances, this level of meta-definitions is provided in a document type definition (DTD). The DTD is complemented with a set of rules that are implemented into a parser API, based on the Document Object Model (DOM). The advantages of the XML approach for the modelling framework are immediate. Type-libraries distributed through Internet are now supported through the mechanisms of namespaces and XLink. The implementation of the API is no longer dependent of a particular database system. This provides much more flexibility in the implementation of the various modules of the VR-DIS system. Being based on the (supposed to become) standard of XML the implementation is much more versatile in its future usage, specifically in a distributed, Internet-based environment.These immediate advantages of the XML approach opened the door to a wide range of applications that are and will be developed on top of the VR-DIS core. Examples of these are the VR-based 3D sketching module [VR-DIS ref., 2000]; the VR-based information-modelling tool that allows the management and manipulation of information models for design in a VR environment [VR-DIS ref., 2000]; and a design-knowledge capturing module that is now under development [first author et al., 2000a and 2000b]. The latter module aims to assist the designer in the recognition and utilisation of existing and new typologies in a design situation. The replacement of the OODB implementation of the API by the XML implementation enables these modules to use distributed Feature databases through Internet, without many changes to their own code, and without the loss of the flexibility and extensibility of conceptual schemas that are implemented as part of the API. Research in the near future will result in Internet-based applications that support designers in the utilisation of distributed libraries of product-information, design-knowledge, case-bases, etc.The paper roughly follows the outline of the abstract, starting with an introduction to the VR-DIS project, its objectives, and the developed theory of the Feature-modelling framework that forms the core of it. It briefly discusses the necessity of schema evolution, flexibility and extensibility of conceptual schemas, and how these capabilities have been addressed in the framework. The major part of the paper describes how the previously mentioned aspects of the framework are implemented in the XML-based approach, providing details on the so-called meta-layer, its definition in the DTD, and the parser rules that complement it. The impact of the XML approach on the functionality of the VR-DIS modules and the system as a whole is demonstrated by a discussion of these modules and scenarios of their usage for design tasks. The paper is concluded with an overview of future work on the sharing of Internet-based design information and design knowledge.

title Study of digital morphing tools during the design process - Application of freeware software and of tools in commercial products as well as their integration in AutoCAD
source SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary This research work examines methods of experimental designing with CAAD in a CAD laboratory with architecture students as the testing persons. Thereby the main focus is on the early phase of finding forms, in which different techniques with digital media are tried out in the didactic architectural design lessons. In these work have been traced the influences of the media employed on the design processes and combined the approaches of current CAAD research with aspects from classic design theory. For mathematical rules of proportion, atmospheric influence factors and analogy concepts in architecture, I have developed design methods which have been applied and verified in several series of seminars. (Kirschner, U.: 2000, Thesis, a CAAD supported architectural design teaching, Hamburg, school of arts). Previous experimental exercises showed that morphological sequences of modeling are effective sources for playful designing processes. In the current work these approaches are enhanced and supplemented by different morphological architectural concepts for creating shapes. For this purpose 2D based software like Morphit, Winmorph and other freeware were used. Whereas in the further development of this design technique we used 3D freeware morphing programs like zhu3D or Blender. The resulting morphological shapes were imported in CAD and refined. Ideally the morphing tool is integrated in the modeling environment of the standard software AutoCAD. A digital city model is the starting basis of the design process to guarantee the reference to the reality. The applied design didactic is predicated on the theories of Bernhard Hoesli. The act of designing viewed as „waiting for a good idea“ is, according to him, unteachable; students should, in contrast, learn to judge the „the force of an idea“. On the subject of morphology a form-generating method in the pre-design phase has been tested. Starting from urban-planning lines on an area map, two simple geometric initial images were produced which were merged by means of morphing software. Selected images from this film sequence were extruded with CAAD to produce solid models as sectional drawings. The high motivation of the students and the quality of the design results produced with these simple morphing techniques were the reason for the integration of the artistic and scientific software into the creative shape modeling process with the computer. The students learned in addition to the „bottom up “and „ top down” new design methods. In the presentation the properties and benefits of the morphing tools are presented in tables and are analyzed with regard to the architectural shape generating in an urban context. A catalogue of criteria with the following topics was developed: user friendliness, the ability of integrating the tools or as the case may be the import of data into a CAD environment, the artistic aspects in terms of the flexibility of shape generating as well as the evaluation of the aesthetic consideration of shapes.

title Redirecting design generation in architecture
source International Conference on Generative Art
summary Design generation has been the traditional culmination of computational design theory in architecture. Motivated either by programmatic and functional complexity (as in space allocation) or by the elegance and power of representational analyses (shape grammars, rectangular arrangements), research has produced generative systems capable of producing new designs that satisfied certain conditions or of reproducing exhaustively entire classes (such as all possible Palladian villas), comprising known and plausible new designs. Most generative systems aimed at a complete spatial design (detailing being an unpopular subject), with minimal if any intervention by the human user / designer. The reason for doing so was either to give a demonstration of the elegance, power and completeness of a system or simply that the replacement of the designer with the computer was the fundamental purpose of the system. In other words, the problem was deemed either already resolved by the generative system or too complex for the human designer. The ongoing democratization of the computer stimulates reconsideration of the principles underlying existing design generation in architecture. While the domain analysis upon which most systems are based is insightful and interesting, jumping to a generative conclusion was almost always based on a very sketchy understanding of human creativity and of the computer's role in designing and creativity. Our current perception of such matters suggests a different approach, based on the augmentation of intuitive creative capabilities with computational extensions. The paper proposes that architectural generative design systems can be redirected towards design exploration, including the development of alternatives and variations. Human designers are known to follow inconsistent strategies when confronted with conflicts in their designs. These strategies are not made more consistent by the emerging forms of design analysis. The use of analytical means such as simulation, couple to the necessity of considering a rapidly growing number of aspects, means that the designer is confronted with huge amounts of information that have to be processed and integrated in the design. Generative design exploration that can combine the analysis results in directed and responsive redesigning seems an effective method for the early stages of the design process, as well as for partial (local) problems in later stages. The transformation of generative systems into feedback support and background assistance for the human designer presupposes re-orientation of design generation with respect to the issues of local intelligence and autonomy. Design generation has made extensive use of local intelligence but has always kept it subservient to global schemes that tended to be holistic, rigid or deterministic. The acceptance of local conditions as largely independent structures (local coordinating devices) affords a more flexible attitude that permits not only the emergence of internal conflicts but also the resolution of such conflicts in a transparent manner. The resulting autonomy of local coordinating devices can be expanded to practically all aspects and abstraction levels. The ability to have intelligent behaviour built in components of the design representation, as well as in the spatial and building elements they signify, means that we can create the new, sharper tools required by the complexity resulting from the interpretation of the built environment as a dynamic configuration of co-operating yet autonomous parts that have to be considered independently and in conjunction with each other.   P.S. The content of the paper will be illustrated by a couple of computer programs that demonstrate the princples of local intelligence and autonomy in redesigning. It is possible that these programs could be presented as independent interactive exhibits but it all depends upon the time we can make free for the development of self-sufficient, self-running demonstrations until December.

title Team design from the individual points of viewa humanistic approach
source Timmermans, Harry (Ed.), Fifth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Nijkerk, the Netherlands)
summary This paper deals with design in teams from the individual points of view of all the parties involved in the process: principals, investors, owners, specialists, experts, advisors, officials, builders, users and residents. Taken together, these different points of view enable us to describe decentralised design in its pure form.Discussion of the individual points of view is possible only if one assumes that the parties involved have their own standpoints in the form of a collection of definable goals (all their wishes, efforts, principles, standards etc.), that they will endeavour to achieve those goals and that they will adjust their actions and decisions during the design process to serve those goals. For the elaboration of this individual point of view (of team design in a matrix structure) I shall take as a basis two concepts from decision theory: ‘methodological individualism’ and ‘the actor’s viewpoint’.

summary This paper describes the development of a multimedia system called ADMIRE (an Architectural Design Multimedia Interaction Resource for Education), which enables undergraduate students to understand how to analyse existing buildings dynamically, as well as to develop their own initial architectural design theories. The system contains architectural information in the form of fully rendered models, conceptual illustrations created with a range of CAD software, and multimedia presentations showing various design theoretic analyses. Buildings are described with CAD generated images, and architects with profiles and theories. In addition to rendered designs, there are also conceptual models of each building in the system. Conceptual models are simplified forms of original designs in order to support an analytical understanding of buildings according to various analyses, such as structure, light, circulation, unit to whole, geometry, etc. Each conceptual model constitutes a different analysis of each building. The ADMIRE system links each piece of information to another, so that students can explore architecture and learn about it in a dynamic way. This system demonstrates a new way of learning about architectural analysis through dynamic multimedia computer interaction.
