title The Design and Implementation of a Virtual Studio Environment
source Proceedings of 2nd East-West Conference on Information Technology in Design, 126-137
summary In this paper the authors describe the design and implementation of a virtual studio environment a distribute system for design collaboration across time and space. A virtual studio is defined as an electronic locale i the computer networks, containing distributed resources (both domain-specific design artifacts and generic Computer-Mediated Communication facilities) and inhabited by dispersed designers, whilst the virtual studj0 environment (VSE) refers to such a multi-user environment which supports the creation, operation and management of virtual studios. We'll particularly focus on reporting on the requirement analysis for a VS: the distributed system architecture, the design of the virtual studio model, and the implementation of the VSE server and VSE client programs. Conceptual buildingS design has been chosen as the application domain Advanced distributed computing technologies (CORBA, WWW) have been utilised for the prototyping.

title REAL SCALE MODEL VS. COMPUTER GENERATED MODEL
source Full-Scale Modeling in the Age of Virtual Reality [6th EFA-Conference Proceedings]
summary Advances in electronic design and communication are already reshaping the way architecture is done. The development of more sophisticated and user-friendly Computer Aided Design (CAD) software and of cheaper and more powerful hardware is making computers more and more accessible to architects, planners and designers. These professionals are not only using them as a drafting tool but also as a instrument for visualization. Designers are "building" digital models of their designs and producing photo-like renderings of spaces that do not exist in the dimensional world.

The problem resides in how realistic these Computer Generated Models (CGM) are. Moss & Banks (1958) considered realism “the capacity to reproduce as exactly as possible the object of study without actually using it”. He considers that realism depends on: 1)The number of elements that are reproduced; 2) The quality of those elements; 3) The similarity of replication and 4) Replication of the situation. CGM respond well to these considerations, they can be very realistic. But, are they capable of reproducing the same impressions on people as a real space?

Research has debated about the problems of the mode of representation and its influence on the judgement which is made. Wools (1970), Lau (1970) and Canter, Benyon & West (1973) have demonstrated that the perception of a space is influenced by the mode of presentation. CGM are two-dimensional representations of three-dimensional space. Canter (1973) considers the three-dimensionality of the stimuli as crucial for its perception. So, can a CGM afford as much as a three-dimensional model?

The “Laboratorio de Experimentacion Espacial” (LEE) has been concerned with the problem of reality of the models used by architects. We have studied the degree in which models can be used as reliable and representative of real situations analyzing the Ecological Validity of several of them, specially the Real-Scale Model (Abadi & Cavallin, 1994). This kind of model has been found to be ecologically valid to represent real space. This research has two objectives: 1) to study the Ecological Validity of a Computer Generated Model; and 2) compare it with the Ecological Validity of a Real Scale Model in representing a real space.

summary 2-D CAAD is the standard tool in architectural work and education. whereas 3-dimensional CAAD is still used to present a finished design. This paper demonstrates that experimental design in 3-D allows students to deal with new methods of design. At North East Lower Saxony Polytechnic, 1995 saw the beginning of development of didactic methods for teaching design with the interactive use of common 3-D CAAD tools. Six exercises were devised, the first two being 2-D exercises in urban and layout design. Subsequent steps introduced three styles of architectural designing with 3-D tools. The students selected one of these styles for their three-day exercise in urban planning. Based on the results, three main ways were developed: the "digital toolkit", the "additive design approach" and the "lighting simulation".

source ACADIA Quarterly, vol. 17, no. 4, pp. 16-17
summary Since 1993, we have experimented with Virtual Design Studios (VDS) as an on-going research project that investigates the combination of current computer-aided design (CAD), computer networks (Internet), and computer supported collaborative work (CSCW) techniques to bring together studentsat geographically distributed locations to work in a virtual atelier. In 1993 the theme of the first joint VDS project was in-fill housing for the traditional Chinese walled village of Kat Hing Wai in the New Territories north of Hong Kong, and our partners included MIT and Harvard in Boston (USA), UBC in Vancouver (Canada), and Washington University in St. Louis (USA). In 1994 we were joined by Cornell (USA) and Escola Tecnica Superior d’Arquitectura de Barcelona (Spain) to re-design Li Long housing in Shanghai, and 1995 added the Warsaw Institute of Technology (Poland) for the ACSA/Dupont competition to design a Center for Cultural and Religious Studies in Japan. The 1996 topic was an international competition to design a monument located in Hong Kong to commemorate the return of Hong Kong to Chinese sovereignty in 1997. Communication was via e-mail, the WorldWide Web with limited attempts at VRML, and network video. Several teaching and research experiments conducted through these projects have demonstrated the viability and potential of using electronic, telecommunications, and videoconferencing technologies in collaborative design processes. Results of these VDS have been presented at conferences worldwide, explained in journal papers and published in Virtual Design Studio, edited by J. Wojtowicz, published by HKU Press.

title Integrating Shadow Casting Methodology and Thermal Simulation
source Proceedings of the Solar ‘96 Conference. Asheville, North Carolina: American Solar Energy Society, 1996, pp. 271-276
summary This paper describes an experiment that integrates shadow casting methodology and thermal simulation algorithms developed by the authors. The 3D shadow procedures use a polyhedral representation of solids within a Cartesian space that allows for accurate casting of shadows. The algorithm is also capable of calculating surface areas of polygonal shadows of any arbitrary shape and size. The thermal simulation algorithms – using the Transfer Function Method (TFM) – incorporate the shaded area calculations to better predict solar heat gain from glazing based on transmitted, absorbed, and conducted cooling loads. The paper describes the use of a 3D computer model to illustrate the impact of the pattern and area of shading on the visual and thermal properties of building apertures. The paper discusses the objectives of this experiment, the algorithms used, and their integration. Conclusions and findings are drawn.

title Cultures of Internet: Virtual Spaces, Real Histories, Living Bodies
source Sage, London
summary The Internet is here but have we caught up with all its implications for culture and everyday life? This collection of original articles on the development of computer-mediated communications brings together many of the most accomplished writers on the Net and cyberspace. Cultures of Internet examines the arrival of e-mail and online discussion groups, and considers the prospect of an `online world' - a playground for virtual bodies in which identities are flexible, swappable and disconnected from real-world bodies. The book traces the rise of virtual conviviality and how it supplements the physical encounters between actors in public spaces that are abandoned to the homeless. The book is distinguished by a critical and social tone. For the first time, it presents systematic descriptions of the development of the Internet, its history in the military-industrial complex, the role of state policies leading, for example, to the creation of Minitel, and the building of information `superhighways'. It also explores the development of this technology as a commercialized leisure form and a forum for underground political organization and critique. Accessible and lively, the book draws in contributions from Europe, North America and developing countries. It will appeal to students of sociology, cultural studies and computer studies.

title A knowledge-based model for developing location strategies in a DSS for retail planning
source Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings (Spa, Belgium), August 18-21, 1996
summary Most DSS for retail planning are based on impact assessment models to support the evaluation of plan scenario's. This paper introduces a complementary knowledge-based model to support also the earlier stage of formulating plan scenario's. An analysis of the retail planning problem reveals the main lines of the strategies adopted by most Dutch planners and retailers to achieve their goals. A basic strategy that seems to be appropriate in most problem contexts is formulated in the form of a set of decision tables. Each decision table or system of decision tables specifies for a problem area decision rules to identify and analyse problems and to formulate possible actions. The model is implemented in a DSS where it is used in combination with quantitative impact assessment models. A case study in the area of daily good facilities demonstrates the approach. The major conclusion is that the knowledge-based approach and in particular the decision table technique provides interesting possibilities to implement planning task structures in a DSS environment.

source Education for Practice [14th eCAADe Conference Proceedings / ISBN 0-9523687-2-2] Lund (Sweden) 12-14 September 1996, pp. 65-78
summary This paper focuses on results and findings of an educational project, in which the participating students had to develop a design strategy for an urban plan by using and combining endoscopic and computational design visualisation techniques. This educational experiment attempted to create a link between the Media research programme titled 'Dynamic Perspective' and an educational exercise in design composition. It was conceived as a pilot study, aimed at the investigation of emerging applications and possible combinations of different imaging techniques which might be of benefit in architectural and urban design education and potentially for the (future) design practice. The aim of this study was also to explore the relationship between spatial perception and design simulation. The point of departure for the student exercise was an urban masterplan which the Dynamic Perspective research team prepared for the workshop 'the (in)visible city' as part of the 1995 European Architectural Endoscopy Association Conference in Vienna, Austria. The students taking part in the exercise were asked to develop, discuss and evaluate proposals for a given part of this masterplan by creating images through different model configurations using optical and computer aided visualisation techniques besides more traditional design media.The results of this project indicate that an active and combined use of visualisation media at a design level, may facilitate communication and lead to a greater understanding of design choices, thus creating insights and contributing to design decision-making both for the designers and for the other participants in the design process.

title Human Interpretation of Computer Generated Architectural Images
source Approaches to Computer Aided Architectural Composition [ISBN 83-905377-1-0] 1996, pp. 61-70
summary The hardware and software used by architects to produce drawings and rendered images (static and dynamic) has advanced over the past decade to the point where it is now routine for architects to add rendered (and otherwise manipulated) images to the more routine 2D drawing as a product to convey the building to others. Although the 2D drawing (as plan section, elevation or detail) remains the fundamental and most prevalent kind of image being produced by architects, we regard it as timely to take stock of the effect of how we interpret the computer generated images that are being produced. We want to address the question of how humans, with a wide range of backgrounds and predispositions interpret such images. This paper takes previous studies which consider image interpretation and image generation by computer and begins to apply the techniques and jcndings to contemporary CAD image making.

summary Designers use different symbols and diagrams in their drawings to explore alternatives and to communicate with each other. Therefore, a useful design environment should attempt to infer the designer's intentions from the drawing and, based on this inference, suggest appropriate computational tools for the task at hand. For example, a layout bubble diagram might activate design cases with similar configurations. Scribbles of view lines on a floor plan might bring up a spatial analysis tool. This research aims to develop an integrated digital sketching environment to support early design activities. The paper proposes RT, an intelligent sketch environment that provides the designers with the right tools at the right time.

title A conceptual framework for deriving and analyzing the geometric structures of orthogonal architectural compositions in plan
source Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Spa, Belgium), August 18-21, 1996
summary This paper introduces a conceptual framework for the analysis and generation of the underlying geometry of orthogonal architectural compositions in plan. The proposed framework has three interrelated objectives: (1) to allow the systematic analysis and derivation of the geometric structures of orthogonal architectural compositions in plan, (2) to describe the spatial relations among their constituent elements, and (3) to enumerate the morphological operations involved creating these relations. It comprises of a grammatical formalism and two data structures. The grammatical formalism allows the systematic derivation and analysis of the geometric structures of architectural compositions in plan. The first data structure is a table that enumerates the rules used to derive and/or analyze geometric structures and the sequence of their application. The second data structure is a binary tree that represents the spatial relations between the shapes produced during these processes.

title Spatial Knowledge Acquisition from Maps and Virtual Environments in Complex Architectural Space
source Proc. 16 th Applied Behavioral Sciences Symposium, 22-23 April, U.S. Airforce Academy, Colorado Springs, CO., 1996, 6-10
summary It has often been suggested that due to its inherent spatial nature, a virtual environment (VE) might be a powerful tool for spatial knowledge acquisition of a real environment, as opposed to the use of maps or some other two-dimensional, symbolic medium. While interesting from a psychological point of view, a study of the use of a VE in lieu of a map seems nonsensical from a practical point of view. Why would the use of a VE preclude the use of a map? The more interesting investigation would be of the value added of the VE when used with a map. If the VE could be shown to substantially improve navigation performance, then there might be a case for its use as a training tool. If not, then we have to assume that maps continue to be the best spatial knowledge acquisition tool available. An experiment was conducted at the Naval Postgraduate School to determine if the use of an interactive, three-dimensional virtual environment would enhance spatial knowledge acquisition of a complex architectural space when used in conjunction with floor plan diagrams. There has been significant interest in this research area of late. Witmer, Bailey, and Knerr (1995) showed that a VE was useful in acquiring route knowledge of a complex building. Route knowledge is defined as the procedural knowledge required to successfully traverse paths between distant locations (Golledge, 1991). Configurational (or survey) knowledge is the highest level of spatial knowledge and represents a map-like internal encoding of the environment (Thorndyke, 1980). The Witmer study could not confirm if configurational knowledge was being acquired. Also, no comparison was made to a map-only condition, which we felt is the most obvious alternative. Comparisons were made only to a real world condition and a symbolic condition where the route is presented verbally.

title OPSALC: A computer-integrated operations planning system for autonomous landfill compaction
source Automation in Construction 5 (1) (1996) pp. 39-50
summary Construction workers and operators associated with sanitary waste landfilling operations face significant health risks because of high levels of exposure to harmful solids and gases. Automation of the spreading and compacting processes of a landfilling operation using an autonomous compactor can reduce exposure of workers to the harmful environment, and thereby lead to improved safety of workers. This paper describes a computer-integrated operations planning system that facilitates (1) the design of landfill cells and (2) the generation of area-covering path plans for spreading and compaction processes by the autonomous compactor. The partitioning of a given landfill site into three-dimensional cells is accomplished by a recursive spatial decomposition technique in which the cell sizes are determined using a probabilistic model for waste generation. A recursive sub-division of each cell into monominoes facilitates the system to automatically deal with any differences between the actual amount of waste generated on a particular day and the amount predicted by the probabilistic model. The partitioned configuration of the landfill site is used to generate the path plan for the autonomous compactor using three motion models, namely straight-up, straight-down, and zig-zag. The computer-integrated system is implemented using PHIGS graphics standard and MOTIF toolkit with C-program binding.

source Case Study and Teaching Notes number 99/65, 10 pages, distributed by HKU Centre for Asian Business Cases, Harvard Business School Publishing (HBSP) and The European Case Clearing House (ECCH), June 2000
summary In early 1997; Mr. Anthony Ng; managing director of Anthony Ng Architects Ltd.; was keenly looking forward to a high-tech; paperless new office; which would free his designers from paperwork and greatly improve internal and external communication – a vision that he had had for a couple of years. In 1996; he brought on board a friend and expert in Internet technology to help him realise his vision. In July 1997; his company was to move into its new office in Wan Chai. Their plan was to have in place an Intranet and a web-based document management system when they moved into the new office. But he had to be mindful of resulting changes in communication patterns; culture and expectations. Resistance from within his company was also threatening to ruin the grand plan. Several senior executives were fiercely opposed to the proposal and refused to read a document off a computer screen. But Ng knew it was an important initiative to move his practice forward. Once the decision was made there would be no chance to reconsider; given the workload demands of the new HK$12 billion project. And this decision would mark a watershed in the company’s evolution. This case study examines the challenges and implications of employing IT to support an architectural office.

title The Meaning of CAAD in Architectural Education

source Education for Practice [14th eCAADe Conference Proceedings / ISBN 0-9523687-2-2] Lund (Sweden) 12-14 September 1996, pp. 347-354
summary A brief historical analysis followed by some possible future scenarios The influence of CAD – nowadays more correctly stated with CAAD meaning architectural CAD – has been more and more evident in the university level architectural education. The development process of architectural CAD-courses and wider CAD-curriculums could, at least in Scandinavian countries, be described and simplified with a couple of development steps analyzed here, to give the starting point. And since the process of educational evolution will naturally keep on developing in the future also, some possible future paths concerning both CAD-equipment, CAAD-education and more traditional architectural curriculumns, are described here after the historical analysis. Following commonly used futures studies methods, my intent is not to predict the future, but to give several probable future choices, of which some might come true, and some might not. Some of the paths are evident, some are ideal and some may cause also negative effects. The future of architectural education and CAAD as part of it will certainly appear somehow, very possibly somewhere in the middle of these presented paths. The aim of this presentation is to give the architectural education community – the schools and faculty – a wide perspective view to analyze and plan their local course structures also for the future. The future possibilities are presented here, so that the schools can prepare for the forecoming future changes in their workin environment. Finally, the future will appear the way we will create it.

This challenge lies partially in finding new land for the rapid urban expansion as well as redeveloping existing urban areas especially inner city areas. The urban planning bureau initiated two projects: the revision of the master plan and the development of an urban renewal plan. In both plans the university assisted in spatial data analysis and the development of a spatial data model to support the inner city redevelopment process.

title From shape to style. Shape grammars: Issues in representation and computation, presentation and selection
source University of Toronto
summary Shape grammars provide a graphical mechanism for generating a variety of shapes. A shape grammar is a production system for specifying recursive graphical computations for shapes (finite arrangements of finite lines of non-zero length). The dissertation considers design as a plan in art and confines itself to abstract designs composed of lines of uniform color and thickness. The dissertation develops an implementation of shape grammars in which the drawing is the computation. Restricting itself to non-parametric shape grammars, the dissertation approaches the area as two related topics: computation and representation delineate the internal aspects of the problem; presentation and selection are crucial to the user interface. The dissertation applies shape grammars to design, promoting three claims: First, that this dissertation advances the field of shape grammars, by combining approaches in the humanities with those in science, articulating the issues and providing a solid foundation for future work. Second, supporting quality design depends on enumerating the alternatives and pruning the design space using the visual aspects of design. Third, the generative aspect of design is not as important as its presentation and selection.
