title	VRAD (Virtual Reality Aided Design) in the Early Phases of the Architectural Design Process
source	Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 313-322
summary	With this paper we are introducing a system which supports the early phases of the architectural design process. The system consists of two main components: the software solution ìvoxDesign" and the physical environment "platform". Our aims are: to formulate, develop, and evaluate an architectural design system through the use of VR (virtual reality)-space. The exploration and development of design intentions is supplemented by a new method of three dimensional sketching.

title	Is Design Really Social
source	International Journal of Virtual Reality, 4:1
summary	There are many who will readily agree with Mitchell's assertion that "the most interesting new directions (for computer-aided design) are suggested by the growing convergence of computation and telecommunication. This allows us to treat designing not just as a technical process... but also as a social process." [Mitchell 1995]. The assumption is that design was a social process until users of computer-aided design systems were distracted into treating it as a merely technical process. Most readers will assume that this convergence must and will lead to increased communication between design participants, that better social interaction leads to be better design. The unspoken assumption appears to be that putting the participants into an environment with maximal communication channels will result in design collaboration. The tools provided, therefore, must permit the best communication and the best social interaction. We see a danger here, a pattern being repeated which may lead us into less than useful activities. As with several (popular) architectural design or modelling systems already available, however, computer system implementations all too often are poor imitations manual systems. For example, few in the field will argue with the statement that the storage of data in layers in a computer-aided drafting system is an dispensable approach. Layers derive from manual overlay drafting technology [Stitt 1984] which was regarded as an advanced (manual) production concept at the time many software engineers were specifying CAD software designs. Early implementations of CAD systems (such as RUCAPS, GDS, Computervision) avoided such data organisation, the software engineers recognising that object-based structures are more flexible, permitting greater control of data editing and display. Layer-based systems, however, are easier to implement in software, more familiar to the user and hence easier to explain, initially easier to use but more limiting for an experienced and thoughtful user, leading in the end to a lesser quality in resultant drawings and significant problems in output control (see Richens [1990], pp. 31-40 for a detailed analysis of such features and constraints). Here then we see the design for architectural software faithfully but inappropriately following manual methods. So too is there a danger of assuming that the best social interaction is that done face-to-face, therefore all collaborative design communications environments must mimic face-to-face.

title	Toward a procedure of computer simulation in the restoration of historical architecture
source	AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary	In the field of architectural design, “visualization¨ generally refers to some media, communicating and representing the idea of designers, such as ordinary drafts, maps, perspectives, photos and physical models, etc. (Rahman, 1992; Susan, 2000). The main reason why we adopt visualization is that it enables us to understand clearly and to control complicated procedures (Gombrich, 1990). Secondly, the way we get design knowledge is more from the published visualized images and less from personal experiences (Evans, 1989). Thus the importance of the representation of visualization is manifested.Due to the developments of computer technology in recent years, various computer aided design system are invented and used in a great amount, such as image processing, computer graphic, computer modeling/rendering, animation, multimedia, virtual reality and collaboration, etc. (Lawson, 1995; Liu, 1996). The conventional media are greatly replaced by computer media, and the visualization is further brought into the computerized stage. The procedure of visual impact analysis and assessment (VIAA), addressed by Rahman (1992), is renewed and amended for the intervention of computer (Liu, 2000). Based on the procedures above, a great amount of applied researches are proceeded. Therefore it is evident that the computer visualization is helpful to the discussion and evaluation during the design process (Hall, 1988, 1990, 1992, 1995, 1996, 1997, 1998; Liu, 1997; Sasada, 1986, 1988, 1990, 1993, 1997, 1998). In addition to the process of architectural design, the computer visualization is also applied to the subject of construction, which is repeatedly amended and corrected by the images of computer simulation (Liu, 2000). Potier (2000) probes into the contextual research and restoration of historical architecture by the technology of computer simulation before the practical restoration is constructed. In this way he established a communicative mode among archeologists, architects via computer media.In the research of restoration and preservation of historical architecture in Taiwan, many scholars have been devoted into the studies of historical contextual criticism (Shi, 1988, 1990, 1991, 1992, 1995; Fu, 1995, 1997; Chiu, 2000). Clues that accompany the historical contextual criticism (such as oral information, writings, photographs, pictures, etc.) help to explore the construction and the procedure of restoration (Hung, 1995), and serve as an aid to the studies of the usage and durability of the materials in the restoration of historical architecture (Dasser, 1990; Wang, 1998). Many clues are lost, because historical architecture is often age-old (Hung, 1995). Under the circumstance, restoration of historical architecture can only be proceeded by restricted pictures, written data and oral information (Shi, 1989). Therefore, computer simulation is employed by scholars to simulate the condition of historical architecture with restricted information after restoration (Potier, 2000). Yet this is only the early stage of computer-aid restoration. The focus of the paper aims at exploring that whether visual simulation of computer can help to investigate the practice of restoration and the estimation and evaluation after restoration.By exploring the restoration of historical architecture (taking the Gigi Train Station destroyed by the earthquake in last September as the operating example), this study aims to establish a complete work on computer visualization, including the concept of restoration, the practice of restoration, and the estimation and evaluation of restoration.This research is to simulate the process of restoration by computer simulation based on visualized media (restricted pictures, restricted written data and restricted oral information) and the specialized experience of historical architects (Potier, 2000). During the process of practicing, communicates with craftsmen repeatedly with some simulated alternatives, and makes the result as the foundation of evaluating and adjusting the simulating process and outcome. In this way we address a suitable and complete process of computer visualization for historical architecture.The significance of this paper is that we are able to control every detail more exactly, and then prevent possible problems during the process of restoration of historical architecture.

title	StereoCAD: Three Dimensional Representation
source	Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 343-355
summary	Concepts of stereoscopic vision have been around for more than two thousand years. Despite this long history, its application to the field to architecture and design seems relatively unexplored. Synthesis of two technologies, the stereoscope and the computer, was the focus of the present study. The goal of the research was to determine if computer-generated stereoscopic pairs hold value for architectural design. Using readily available computer technology (Apple Macintosh) the research team modelled and rendered an existing project to verify the degree of correlation between the physical construct, the computer 3D model and resultant correlation between the physical construct, the computer 3D model and resultant rendered stereo-paired representation. The experiments performed in this study have shown that producing stereo-paired images that highly correlate to reality is possible using technology that is readily available in the marketplace. Both the technology required to produce (i.e., personal computer and modelling/rendering software) and view (i.e., modified stereoscope) the images is unimposing. Both devices can easily fit in a studio or a boardroom and together can be utilized effectively to permit designers, clients and end-users to experience proposed spaces and projects. Furthermore, these technologies are familiar (clients and end-users have already experienced them in other applications and settings) and assume a fraction of the cost of more dynamic, immersive virtual reality systems. Working from this base, limitations of the process as well as future applications of computer-generated stereoscopic images are identified.

title	Is Design Really Social

summary	There are many who will readily agree with Mitchell’s assertion that “the most interesting new directions (for computer-aided design) are suggested by the growing convergence of computation and telecommunication. This allows us to treat designing not just as a technical process... but also as a social process.” [Mitchell 1995]. The assumption is that design was a social process until users of computer-aided design systems were distracted into treating it as a merely technical process. Most readers will assume that this convergence must and will lead to increased communication between design participants; that better social interaction leads to be better design. The unspoken assumption appears to be that putting the participants into an environment with maximal communication channels will result in design collaboration. The tools provided; therefore; must permit the best communication and the best social interaction. We think it essential to examine the foundations and assumptions on which software and environments are designed to support collaborative design communication. Of particular interest to us in this paper is the assumption about the “social” nature of design. Early research in computer-assisted design collaborations has jumped immediately into conclusions about communicative models which lead to high-bandwidth video connections as the preferred channel of collaboration. The unstated assumption is that computer-supported design environments are not adequate until they replicate in full the sensation of being physically present in the same space as the other participants (you are not there until you are really there). It is assumed that the real social process of design must include all the signals used to establish and facilitate face-to-face communication; including gestures; body language and all outputs of drawing (e.g. Tang [1991]). In our specification of systems for virtual design communities; are we about to fall into the same traps as drafting systems did?

title	Dynamic Perspective: The Media Research Programme
source	The Future of Endoscopy [Proceedings of the 2nd European Architectural Endoscopy Association Conference / ISBN 3-85437-114-4]
summary	This paper focuses on the Research Programme of the Media Sector at the Faculty of Architecture, Delft University of Technology. The media research objectives for the coming years have been brought together with an overall project: “Dynamic Perspective”. The “dynamic” quality may be interpreted both as movement (visual displacement and registration) and as change (the effects of different options). The four projects which together make up this research programme deal with perception (understanding) and conception (designing and imaging) of urban space: “the architecture of the city”. Specific aspects are the effects of primary and secondary spatial boundaries and the systematic structuring of simulation of visual information. The programme will further concentrate on the development and implementation of relevant techniques (besides “traditional” ones such as the drawing and the architectural model, on multimedia techniques such as endoscopy, computer visualization and development of virtual reality systems), both in education and in design practice. By means of analysis, the creation of visual models of choice and the setting up of experiments, the programme aims at the furthering of theoretical knowledge and at acquiring better insights into the effects of design decisions at an urban level, both for designers and for other participants in the design process. Further development of existing laboratory facilities towards a comprehensive Design Simulation Laboratory is an important aspect of the programme. Within the media research process the Aspern location master plan has been considered as a case study, the findings of which will be presented separately in the workshop sessions.

title	Design Precedents for Virtual Worlds
source	Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 293-302
summary	The usual precedents cited in relation to Cyberspace are William Gibson's book "Neuromancer" and Ridley Scott's film. "Bladerunner". This paper argues that, whilst literature and film are appropriate precedents, there are more suitable sources to refer to when designing virtual worlds. The paper discusses the use of computer modelling in exploring architectonic concepts in three-dimensional space. In doing so it draws on the philosophy of simulation and gives examples from alternative film and literature sources but concludes that one of the most appropriate metaphors is widely available in the form of the television soap opera.

source	Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 739-748
summary	The paper explores group coordination in the design process through communicative innovations brought by computers. It is divided into three main sections. The first is the analysis of the design group coordination and communication. The second introduces the concept of Coordinative Virtual Space: this is a common multi-dimensional space where the group members share design information. The third presents the implementation: each member can connect to the shared space through the computer network and display several projections of the design information space.

title	Linking the Virtual to Reality: CAD & Physical Modeling
source	Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 303-311
summary	Using both study models and digital models for schematic design allows us to take advantage of the strengths of each. Models constructed manually benefit from spontaneous juxtapositions and serendipitous interactions with light and gravity. Converting these models into the digital realm allows the computer to take over in areas that it does best: geometric transformation, rigorous analysis, elaboration and co-ordination of details and complexity. As a project develops, CAD/CAM methods can generate forms or components for verifying the virtual representation. The paradigm of porting data to appropriate software tools needs to be extended to exporting out of and into the physical realm. Connecting to models in real space allows us to use senses that are not yet completely addressed by digital models.

doi	https://doi.org/10.52842/conf.acadia.1995.155
summary	As design processes and products are constantly increasing in complexity, new tools are being developed for the designer to cope with the growing demands. In this paper we describe our research towards a design environment, within which different aspects of design can be combined, elaborated and controlled. New hardware equipment will be combined with recent developments in graphics and artificial intelligence programming to develop appropriate computer based tools and find possible new design techniques. The core of the new design studio comprises intelligent objects in a virtual reality environment that exhibit different behaviours drawn from Artificial Intelligence (AI) and Artificial Life (AL) principles, a part already realised in a tool called 'Sculptor'. The tasks of the architect will focus on preferencing and initiating good tendencies in the development of the design. A first set of software agents, assistants that support the architect in viewing, experiencing and judging the design has also been conceptualised for this virtual design environment. The goal is to create an optimised environment for the designer, where the complexity of the design task can be reduced thanks to the support made available from the machine.

source	Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 687-697
summary	This paper outlines the way in which studying designers at work on real problems can inform the development of new computer aided architectural design systems. From a number of studies of designers in various domains, supporting the communications of designers is re-conceptualized into one of transmitting and storing process ephemera, rather than normalizing representations. After characterizing process ephemera, an example from one of the studies is described in detail. The paper concludes with implications for the design of collaborative CAAD systems.

title	The Search for the Logical Algorithm of the Town-planning Process
source	CAD Space [Proceedings of the III International Conference Computer in Architectural Design] Bialystock 27-29 April 1995, pp. 275-282
summary	The creation of such models of material and spatial environment that can guarantee the most efficient passing of the virtual processes is considered to be one of the main goals for the town planning. But sometimes this goal is not achieved because of the far-fetched space organization accepted in the model, that does not always coincide with the real processes of vital activity. This report does not focus particularly on the damage which is caused by the realization of such defective models. But it is very important to find out the way for complete elimination of the reasons mentioned above. We should also take into account that means of cognition available at the moment are among the basic determiners, which define that "shear" of reality and also that comprehension level of objective laws governing this stage of social development. That is why our conception of the town-planning processes is in constant development and improvement: it gradually approximates to the truth, but, certainly, does not entirely perceive it.

title	The Role of Computers in Synchronous Collaborative Design
source	Proceedings of the 14th International Congress on Cybernetics. Namur, Belgium: International Association for Cybernetics, 1995, pp. 71-76
summary	In this paper we discuss the role of computers in supporting real-time synchronous design among geographically dispersed team members using the global network of computers known as the Internet. To enable efficient and functional synchronous design activity, we advocate a new generation of design-oriented software that combines collaboration technologies with a meaningful and parsimonious representation scheme. We are particularly interested in supporting the early design phases, wherein many of the most important decisions are made and collaboration is most important. These activities are crucial to the evolution and quality of the final design, and they are receptive to and can benefit from computer support. Furthermore, these are precisely the areas where current CAD systems are weakest. As a general theoretical direction, our emphasis is not on integrated databases, but rather on shared protocols of interaction that are independent of implementation and storage schemes. Our first experimental phase involved the simultaneous development and testing of prototypes for a Synchronous Collaborative Design Environment (SYCODE) on heterogeneous computer systems at two geographically dispersed sites. The applications were developed independently, based on a verbal description of protocols, with minimal sharing of actual source code. Though their user interfaces and implementation details are different, these prototypes allow multiple users to share a virtual design space - both within and between the remote sites - in which to create and manipulate architectural elements.

title	LOST IN SPACE? ARCHITECTURAL PSYCHOLOGY - PAST, PRESENT, FUTURE
source	Full-Scale Modeling in the Age of Virtual Reality [6th EFA-Conference Proceedings]
summary	A methodological review by Kaminski (1995) summed up five perspectives in environmental psychology - patterns of spatial distribution, everyday “jigsaw puzzles”, functional everyday action systems, sociocultural change and evolution of competence. Architectural psychology (named so at the Strathclyde conference 1969; Canter, 1973) as psychology of built environments is one leg of environmental psychology, the second one being psychology of environmental protection. Architectural psychology has come of age and passed its 25th birthday. Thus, a triangulation of its position, especially in Central Europe, seems interesting and necessary. A recent survey mainly on university projects in German-speaking countries (Kruse & Trimpin, 1995) found a marked decrease of studies in psychology of built environments. 1994, 25% of all projects were reported in this category, which in 1975 had made up 40% (Kruse, 1975). Guenther, in an unpublished survey of BDP (association of professional German psychologists) members, encountered only a handful active in architectural psychology - mostly part-time, not full-time. 1996, Austria has two full-time university specialists. The discrepancy between the general interest displayed by planners and a still low institutionalization is noticeable. How is the research situation? Using several standard research data banks, the author collected articles and book(chapter)s on architectural psychology in German- and English-language countries from 1990 to 1996. Studies on main architecture-psychology interface problems such as user needs, housing quality evaluations, participatory planning and spatial simulation / virtual reality did not outline an “old, settled” discipline, but rather the sketchy, random surface of a field “always starting anew”. E.g., discussions at the 1995 EAEA-Conference showed that several architectural simulation studies since 1973 caused no major impact on planner's opinions (Keul&Martens, 1996). “Re-inventions of the wheel” are caused by a lack of meetings (except this one!) and of interdisciplinary infrastructure in German-language countries (contrary to Sweden or the United States). Social pressures building up on architecture nowadays by inter-European competition, budget cuts and citizen activities for informed consent in most urban projects are a new challenge for planners to cooperate efficiently with social scientists. At Salzburg, the author currently manages the Corporate Design-process for the Chamber of Architecture, Division for Upper Austria and Salzburg. A “working group for architectural psychology” (Keul-Martens-Maderthaner) has been active since 1994.

summary	We can now look back over more than three decades of CAD research, software development, and deployment in practice. In that time, several guiding paradigms have emerged - then have eventually been superseded(or, at least, extended and augmented by new ones. In this paper I briefly glance backward at successive paradigms, consider what each has contributed to our understanding of the subject, then go on to consider the latest - CAD as a network-supported, social process.

title	Ray Tracing – New Chances, Possibilities and Limitations in AutoCAD
source	CAD Space [Proceedings of the III International Conference Computer in Architectural Design] Bialystock 27-29 April 1995, pp. 121-136
summary	Realistic image synthesis is nowadays widely used in engineering applications. Some of these applications, such as architectural, interior, lighting and industrial design demand accurate visualization of non-existent scenes as they would look to us, when built in reality. This can only be archived by using physically based models of light interaction with surfaces, and simulating propagation of light through an environment. Ray tracing is one of the most powerful techniques used in computer graphics, which can produce such very realistic images. Ray tracing algorithm follows the paths of light rays backwards from observer into the scene. It is very time consuming process and as such one could not be developed until proper computers appeared, In recent years the technological improvements in computer industry brought more powerful machines with bigger storage capacities and better graphic devices. Owing to increasing these hardware capabilities successful implementation of ray tracing in different CAD software became possible also on PC machines. Ray tracing in AutoCAD r.12 - the most popular CAD package in the world - is the best of that example. AccuRender and AutoVision are an AutoCAD Development System (ADS) applications that use ray tracing to create photorealistic images from 3D AutoCAD models. These ,internal"' applications let users generate synthetic images of threedimensional models and scenes entirely within AutoCAD space and show effects directly on main AutoCAD screen. Ray tracing algorithm accurately calculates and displays shadows, transparency, diffusion, reflection, and refraction from surface qualities of user-defined materials. The accurate modelling of light lets produce sophisticated effects and high-quality images, which these ray tracers always generates at 24-bit pixel depth,"providing 16,7 million colours. That results can be quite impressive for some architects and are almost acceptable for others but that coloured virtual world, which is presented by ray tracing in AutoCAD space in such convincing way, is still not exactly the same as the real world. Main limitations of realism are due to the nature of ray tracing method Classical ray tracing technique takes into account the effects of light reflection from neighbouring surfaces but, leaves out of account the ambient and global illumination arising out of complex interreflections in an environment. So models generated by ray tracing belong to an "ideal" world where real materials and environment can't find their right place. We complain about that fact and say that ray tracing shows us "too specular world", but (...) (...) there is anything better on the horizon? It should be concluded, that typical abilities of today's graphics software and hardware are far from exploited. As was observed in literature there have been various works carried along with the explicit intention of overcoming all these ray tracing limitations, These researches seem to be very promising and let us hope that their results will be seen in CAD applications soon. As it happens with modelling, perhaps the answer will come from a variety of techniques that can be combined together with ray tracing depending on the case we are dealing with. Therefore from the point of view of an architects that try to keep alive some interest on the nature of materials and their interaction with form, "ray tracing" seems to be right path of research and development that we can still a long way follow, From the point of view of the school, a critical assimilation of "ray tracing" processes is required and one that might help to determinate exactly their distortions and to indicate the correct way of its development and right place in CAAD education. I trust that ray tracing will become standard not only in AutoCAD but in all architectural space modelling CAD applications and will be established as a powerful and real tool for experimental researches in architectural design process. Will be the technological progress so significant in the nearest future as it is anticipated?

title	The visual harmony between new and old materials in the restoration of historical architecture: A study of computer simulation

summary	In the research of historical architecture restoration, scholars respectively focus on the field of architectural context and architectural archeology (Shi, 1988, 1990, 1991, 1992, 1995; Fu, 1995, 1997; Chiu, 2000) or on architecture construction and the procedure of restoration (Shi, 1988, 1989; Chiu, 1990). How to choose materials and cope with their durability becomes an important issue in the restoration of historical architecture (Dasser, 1990; Wang, 1998).In the related research of the usage and durability of materials, some scholars deem that, instead of continuing the traditional ways that last for hundreds of years (that is to replace new materials with old ones), it might be better to keep the original materials (Dasser, 1990). However, unavoidably, some of the originals are much worn. Thus we have to first establish the standard of eliminating components, and secondly to replace identical or similar materials with the old components (Lee, 1990). After accomplishing the restoration, we often unexpectedly find out that the renewed historical building is too new that the sense of history is eliminated (Dasser, 1990; Fu, 1997). Actually this is the important factor that determines the accomplishment of restoration. In the past, some scholars find out that the contrast and conflict between new and old materials are contributed to the different time of manufacture and different coating, such as antiseptic, pattern, etc., which result in the discrepancy of the sense of visual perception (Lee, 1990; Fu, 1997; Dasser, 1990).In recent years, a number of researches and practice of computer technology have been done in the field of architectural design. We are able to proceed design communication more exactly by the application of some systematic softwares, such as image processing, computer graphic, computer modeling/rendering, animation, multimedia, virtual reality and so on (Lawson, 1995; Liu, 1996). The application of computer technology to the research of the preservation of historical architecture is comparatively late. Continually some researchers explore the procedure of restoration by computer simulation technology (Potier, 2000), or establish digital database of the investigation of historical architecture (Sasada, 2000; Wang, 1998). How to choose materials by the technology of computer simulation influences the sense of visual perception. Liu (2000) has a more complete result on visual impact analysis and assessment (VIAA) about the research of urban design projection. The main subjects of this research paper focuses on whether the technology of computer simulation can extenuate the conflict between new and old materials that imposed on visual perception.The objective of this paper is to propose a standard method of visual harmony effects for materials in historical architecture (taking the Gigi Train Station destroyed by the earthquake in last September as the operating example).There are five steps in this research: 1.Categorize the materials of historical architecture and establish the information in digital database. 2.Get new materials of historical architecture and establish the information in digital database. 3.According to the mixing amount of new and old materials, determinate their proportion of the building; mixing new and old materials in a certain way. 4.Assign the mixed materials to the computer model and proceed the simulation of lighting. 5.Make experts and the citizens to evaluate the accomplished computer model in order to propose the expected standard method.According to the experiment mentioned above, we first address a procedure of material simulation of the historical architecture restoration and then offer some suggestions of how to mix new and old materials.By this procedure of simulation, we offer a better view to control the restoration of historical architecture. And, the discrepancy and discordance by new and old materials can be released. Moreover, we thus avoid to reconstructing ¡§too new¡¨ historical architecture.

title	A Social Dimension to Digital Architectural Practice
source	Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 291-304
summary	In 1995 the first in a series of three books were published by Academy Editions, that have since become a vivid handbook that documents how designers responded to the development of architectural drawing applications and the growth of the internet, to establish a form of digital architecture. Offering dramatic images and emotive texts, many of the architects and designers featured in these books deeply affected the perception of digital architecture’s mission by students and elements of the design community. Concentrating upon how to resolve the view that time and space are separate dimensions, and the immersive and dematerial potentials of cyberspace, the developments of this ‘cyberromanticism’ (Coyne 1999) ultimately were not used to sustain digital architectural activity. This paper uses the Academy Editions series to understand how such a vivid aspect of digital architecture failed to fulfil its aspirations. The paper begins by establishing the premise for digital architecture through a link with mainstream architectures interest in the concept of shelter. Through a summary of the practical and theoretical methods outlined by the early designers within the series of publications, the paper demonstrates the critical potential of the field. However a summary of how the proliferation of early imagery fuelled a visual mannerism traces how the third Architects in Cyberspace publication represented a crisis in both identity and practice. The paper then identifies an opportunity for recovering the theoretical imperatives within digital architecture by reflecting upon the emergence of ‘interactive architectures’ use of a ‘social’ dimension that was previously hindered by the use of computer applications in early digital architecture. The paper closes with a reference to two of the authors practical projects that use social data to inform the generation of digital architecture.

title	Multivalent Architectural Case Information for Creative Reasoning
source	Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 543-554
summary	The theoretical underpinnings, practical and technical implementation of a multimedia database to support creative designing is presented through a prototype system which would go on-line in the near future. At the heart of the system is the notion that architectural knowledge is multivalent ñ requiring the means for recombination in new and different ways to support design thinking. The system also attempts to deal with the practical issues of case building, 3D modelling, interface design and technical clarity.
