title	Understanding the AR-VR Based Architectural Design Workflow among Selected Danish Architecture Practices

summary	Virtual reality (VR) and augmented reality (AR) have been proposed to be additional architectural design mediums for at least 25 years (Dagit, 1993). Despite rapid technical and technological development, it has not been adopted into architectural design practices as compared to academia and research. Surveys from the American Institute of Architects (AIA) and Royal Institutes of British Architects (RIBA) demonstrate the state of architectural practices; 72% of architects and 65% of architects respectively are not using any kind of virtual, augmented, or mixed reality in their practices(RIBA and Microsoft, 2018; Hampson, 2020). In this paper, the authors investigate the state of practices, issues, challenges, and opportunities of the utilization of virtual, augmented, and mixed realities in six architectural practices in the Danish context. Three of the practices are large architectural practices, one medium-sized practice specializing in institutional, healthcare and cultural architecture, and one firm designing private family houses, kindergartens, daycares and places for people with disability and, one experimental design studio. All these practices have used VR/AR in their projects to various degrees. In recent years Danish architectural practices have been involved in various VR/AR-based exhibitions, demonstrations, and tool developments to promote the usage of the same in design practice. Through a set of qualitative interviews with personnel from key architectural practices, the authors would like to demonstrate the present state of practices. The investigation explores the usage of VR and AR in Danish architecture practices by identifying challenges and opportunities regarding skill levels, architectural typology, use cases, toolchains, and workflow and shows similarities and differences between traditional and VR-based design processes. The main findings show how VR/AR-based visualization helps architects to perceive spatiality and also ushers creativity through immersion and overlays.

title	The Vector-drawing as a Means to Unravel Architectural Communication in the Past
source	[eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
doi	https://doi.org/10.52842/conf.ecaade.1993.x.q9a
summary	Unlike in painting, in architecture one single person never controls the whole process between conception and realization of a building. Ideas of what the building will eventually look like, have to be conveyed from patron to the actual builders, by way of drawings. Generally the architect is the key-figure in this process of communication of visual ideas. Nowadays many architects design their new buildings by using computers and Computer-Aided (Architectural) Design programs like AutoCad and VersaCAD. Just like traditional drawings, all these computer drawings are in fact vector-drawings; a collection of geometrical primitives like lines, circle segments etc. identified by the coordinates of their end points. Vector-based computer programs can not only be used to design the future, but also as a means to unravel the architectural communication in the past. However, using the computer as an analyzing tool for a better comprehension of the past is not as simple as it seems. Historical data from the past are governed by unique features of date and place. The complexity of the past combined with the straightforwardness of the computer requires a pragmatic and basic approach in which the computer acts as a catalytic agent, enabling the scholar to arrive manually at his own - computer-assisted - conclusions. From this it turns out that only a limited number of projects of a morphological kind are suited to contribute to new knowledge, acquired by the close-reading of the information gained by way of meaningful abstraction. An important problem in this respect is how to obtain the right kind of architectural information. All four major elements of the building process - architect, design, drawing and realization - have their own different and gradually shifting interpretations in the past. This goes especially for the run-of-the-mill architecture which makes up the larger part of the historical urban environment. Starting with the architect, one has to realize that only a very limited part of mainstream architecture was designed by architects. In almost all other cases the role of the patron and the actual builder exceeds that of the architect, even to the extent that they designed buildings themselves. The position of design and drawing as means of communication also changed in the past. Until the middle of the nineteenth century drawings were not the chief means of communication between architects and builders, who got the gist of the design from a model, or, encountering problems, simply asked the architect or supervisor. From the nineteenth century onwards the use of drawings became more common, but almost never represented the building entirely "as built". In 1991 I published my Ph.D. thesis: Constructing the past: computerassisted architectural-historical research: the application of image-processing using the computer and Computer-Aided Design for the study of the urban environment, illustrated by the use of treatises in seventeenth-century architecture (Utrecht 1991). Here, a reconstruction of this historical communication process will be presented on the basis of a project studying the use of the Classical orders as prescribed in various architectural treatises, compared to the use of the orders in a specific group of still existing buildings in The Netherlands dating from the late sixteenth and entire seventeenth century. Comparisons were made by using vector-drawings. Both the illustrations in the the treatises and actual buildings were "translated" into computer-drawings and then analyzed.

title	Building a spatially immersive display - HUTCAVE
source	Helsinki University of Technology, Espoo, Finland
summary	A spatially immersive display is a display that surrounds the user, thus removing or alleviating many disadvantages the common virtual reality systems, such as head-mounted displays have. The most common example of these spatially immersive displays is the CAVE, "CAVE Automatic Virtual Environment", first built at University of Illinois, in 1993. It combines a large field-of-view with high-resolution images and a high frame refresh rate. In this work, the current Virtual Reality (VR) and Virtual Environment (VE) systems are examined, and then the CAVE construction is presented. Principles of stereo vision are explained and current methods of obtaining both autostereoscopic and stereopsis-based vision are reviewed. Aspects of different projection methods, screens, mirrors, projectors, tracking equipment, and computing systems are examined. Also, recent work in CAVE audio, so far neglected in research, is presented. Some of the mathematics is also explained, since in most CAVE-systems some sort of optical folding is necessary. Two cases of CAVE construction are presented, both at the Helsinki University of Technology. The first is a single-wall installation built as a temporary system, and the second is a four-sided CAVE at a new location, superseding the temporary installation. Finally the conclusions are presented, both from the process management point of view, and from the technical point of view, examining the good and bad points of the chosen solutions.

title	The Changing Image of the City
source	University of Utrecht
summary	The image and structure of a town are constantly subject to a dynamic process of change and continuity. Visual material, such as photographs, historical maps, town plans, drawings and prints, show us the impact of these changes on the image of a town. The main point of departure of this study stems from the question of how this process of change and continuity is visually detectable in a town or city. The fact that the ideas about the appearance of a city (gradually) change, can be read from the often subtle changes in the townscape. Though in many cases we have a general knowledge of the choices made in urban management, the most difficult problem is to detect the underlying decisions. This raises the question to what extent these changes and also the continuities are the result of deliberate choices in urban management and to what extent they are autonomous developments in the townscape resistant to interventions. Using different kinds of visual information as a basis, computer visualization techniques are used in the present study to examine some cartographic maps and to reconstruct the urban development in the twentieth century of the town of Heusden three-dimensionally in significant phases. The resulting visualization provides us with a tool for a better understanding of the dynamics of urban transformation processes, typologies and morphological changes and continuities.

title	Behavior Modeling in Design System Development
source	CAAD Futures ‘93 [Conference Proceedings / ISBN 0-444-89922-7] (Pittsburgh / USA), 1993, pp. 335-354
summary	We describe the development approach for a software environment to support the early phases in building design called SEED. The combination of capabilities offered by SEED to designers is novel and includes the integrated handling of solution prototypes. We give the reasons for using an object-oriented software engineering approach in the development of the system, which starts with a comprehensive behavioral model of the system from the user's perspective based on actors and use cases. We illustrate results from the first development phase and sketch the next phases. At the time of the CAAD Futures '93 conference, we will be able to report our experience in developing a first system prototype and to demonstrate the prototype.

title	A Computer-Assisted Diagramming System
source	Swiss Federal Institute of Technology, ETH Zurich
summary	This research investigates characteristics and generation of graphic diagrams used in support of analysis, presentation and synthesis of information in various domains. The research is aimed at the development of a software system which can be used to specify, generate and manipulate diagrams similar to the way they are represented and operated upon in traditional media.Diagrams are graphic representations of symbolic propositions that allow tentative reasoning and inferencing, and enable a person to focus on selected aspects of a situation that are deemed of interest. The economy and directness of expression found in diagrams seem to be the prime reasons why they are so ubiquitous in many domains. Despite these advantages, studies into supporting diagrammatic representations using computers are rather sparse. This research is an attempt at developing a comprehensive framework of thought in this direction.In the context of design disciplines like architecture, this research forms a part of the continuum of studies in computer aided design techniques and tools. While a large number of tools and techniques in CAD have emerged so far, usage of such tools, due to their underlying representations, expects and demands commitment of too many details too early in the design process. This research is aimed at characterizing and developing a computer based diagramming system to support tentative reasoning using diagrams, and thus hopes to extend the scope of CAD environments in design.The thesis first articulates motivations for this topic in detail. Next, a discussion on the role played by diagrams as conceptual tools in various domains is presented. It is followed by a detailed look at characteristics and components of diagrams viewed as a graphic communication system. Next, a comprehensive set of requirements for an ideal software environment for diagramming tasks is developed. A prototype system called CDT was implemented and is used to demonstrate ideas developed in this research. The study concludes with some observations on contributions of this research effort and possible future extensions.

title	A decision-making process for choice of a flexible internal partition option in multi-unit housing using decision theory techniques
source	Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary	Recent demographic changes have increased the heterogeneity of user groups in the North American housing market. Smaller households (e.g. elderly, single parent) have non-traditional spatial requirements that cannot be accommodated within the conventional house layout. This has created renewed interest in Demountable/Flexible internal partition systems. However, the process by which designers decide which project or user groups are most suited for the use of these systems is quite often complex, non-linear, uncertain and dynamic, since the decisions involve natural processes and human values that are apparently random. The anonymity of users when mass housing projects are conceptualized, and the uncertainty as to the alternative to be selected by the user, given his/her constantly changing needs, are some contributing factors to this effect. Decision Theory techniques, not commonly used by architects, can facilitate the decision-making process through a systematic evaluation of alternatives by means of quantitative methods in order to reduce uncertainty in probabilistic events or in cases when data is insufficient. The author used Decision Theory in the selection of flexible partition systems. The study involved a multi-unit, privately initiated housing project in Montreal, Canada, where real site conditions and costs were used. In this paper, the author outlines the fundamentals of Decision Theory and demonstrates the use of Expected Monetary Value and Weighted Objective Analysis methods and their outcomes in the design of a Montreal housing project. The study showed that Decision Theory can be used as an effective tool in housing design once the designer knows how to collect basic data.

title	Case-Based Structural Design - using weakly structured product and process information
source	Chalmers University of Technology, Division of Steel and Timber Structures, Publ. S 00:7, Göteborg
summary	Empirical knowledge plays a significant role in the human reasoning process. Previous experiences help in understanding new situations and in finding solutions to new problems. Experience is used when performing different tasks, both those of routine character and those that require specific skill. This is also the case for structural designers. Over 50% of the work done by the designer on a day-to-day basis is routine design that consists of modifying past designs (Moore 1993). That is, most of the design problems that the designer solves have been solved before, in many cases over and over again. In recent years, researchers have started to study if cases (information about specific problem-solving experiences) could be used as a representation of experiential knowledge. Making use of past experience in the form of cases is commonly known as Case-Based Reasoning (CBR). A requirement for Case-Based Design (Case-Based Reasoning applied in design) to be successful is that the design information is computerized. One information type used in structural design that is starting to become computerized is the one in design calculation documents. Such information is weakly structured (which holds for much of the information representing experience) and it contains both product and process information. In this thesis it is shown how the weak structure of this information can be used to subdivide it into components, which in turn makes it possible to apply the object-oriented abstraction principles also to this kind of information. It is also shown how the detailed design process can be represented and how this representation can facilitate automatic acquisition, retrieval of relevant old design information, and adaptation of this information. Two prototypes BridgeBase and ARCADE have been developed, where the principles described above are applied. Using ARCADE, the more general of these two prototypes, it is presented how information in computerized design calculation documents, gathered from real projects, can serve as containers and carriers for both project information and experience. The experience from the two prototypes shows that Case-Based Design can be usable as a tool for structural engineers.

title	Information visualization using 3D interactive animation
source	Communications of the ACM 36(4): 57-7 1
summary	UI innovations are often driven by a combination of technology advances and application demands. On the technology side, advances in interactive computer graphics hardware, coupled with low-cost mass storage, have created new possibilities for information retrieval systems in which UIs could play a more central role. On the application side, increasing masses of information confronting a business or an individual have created a demand for information management applications. In the 1980s, text-editing forced the shaping of the desktop metaphor and the now standard GUI paradigm. In the 1990s, it is likely that information access will be a primary force in shaping the successor to the desktop metapho. This article presents an experimental system, the Information Visualizer (see figure 1), which explores a UI paradigm that goes beyond the desktop metaphor to exploit the emerging generation of graphical personal computers and to support the emerging application demand to retrieve, store, manipulate, and understand large amounts of infromation. The basic problem is how to utilize advancing graphics technology to lower the cost of finding information and accessing it once found (the information's "cost structure"). We take four broad strategies: making the user's immediate workspace larger, enabling user interaction with multiple agents, increasing the real-time interaction rate between user and system, and using visual abstraction to shift information to the perceptual system to speed information assimilation and retrieval.

title	Knodes: Knowledge-Based Design Decision Support
source	CAAD Futures ‘93 [Conference Proceedings / ISBN 0-444-89922-7] (Pittsburgh / USA), 1993, pp. 357-374
summary	This paper describes the work in progress to develop a knowledge-based design support (KNODES) environment. The KNODES environment is intended to improve a designer's decision making potential, and to assist designers in a broad range of disciplines by making design knowledge and information more accessible. The framework exists as a multi-layered knowledge-based system reflecting both generic and domain specific aspects of the design activity and is designed to: enable the rapid dissemination of new design information, thus responding to shifts in design standards; take advantage of existing empirical design tools in unstructured areas of the design process; accommodate changes in user expectations and technological innovations at both the system and domain levels thus ensuring long term continuity and support,- offer multiple view points of the same design data by means of interchangeable interpreters. A prototype building design framework configured using the KNODES development tools is used to illustrate some of the salient features of the framework. Finally the paper will conclude with some insights into how such a design framework may be used as a knowledge acquisition tool in order to derive and formalise models of the design process.

summary	Architects and urban designers are increasingly using computers in their attempt to improve decision making in urban design. Most existing systems emphasize hard data such as statistics, land use data, etc. In recent years with the use of more powerful computers we have seen a greater emphasis on managing visual data. Computer systems are being used to generate urban models and simulations of the various kinds of impact new developments have on the existing cityscape. This project emphasizes the use of visual data. The purpose of the research has been to develop a computer system for urban designers to use in analyzing urban architectural qualities. Therefore this project focuses on applying traditional methods and theories of urban designers rather than developing new computer techniques. The traditional methods and theories of urban designers fall within the category which the French theorist Francoise Choay calls Pre-urbanism and Urbanism - the Cultural Model. Theorists within this category include Camillo Sitte, Gordon Cullen, Kevin Lynch, Leon Krier, Aldo Rossi, Michael Trieb, Roger Tranzick and Thiis-Evensen. This computer system has been developed as a prototype in order to gain experience and knowledge for future development of a large system. Later development will be based upon a vectorized threedimensional model of a whole city using texture mapping and tracing techniques to annotate important architectural features. The computer system consists of the basic analysis module supplied with a simulation unit and a theory unit. With this analytical tool, analysis is conducted on three different urban scales. The prototype has been developed on the Macintosh computer with SuperCard as the authoring tool. The computer system was developed as a prototype for Danish Urban Designers and is currently being tested in conjunction with the city of Viborg, Denmark. ( population 55,000). Located in Jutland, Viborg was the capital of Denmark around the year 1000. It now functions as a center for regional government. Viborg was selected as the test site because of its historical core.

title	Virtual Reality - Applications and Explorations
source	Academic Press Professional
summary	Virtual and Artificial Reality have become in the last few years one of the major new hype words. Subsequently there has been a plethora of glossy books and droll conference proceedings describing various systems and hardware implementation problems. As has always been discovered in computer science the major effort is in designing and building the software applications. Alan's aim has been to ignore the hardware side and concentrate on the far larger and almost impossible problem of what to do with it. This book is a collection of ten essays trying to look slightly into the future and define actual uses for Virtual Reality kits rather than showing off expensive hardware. This has resulted in a series of topics, each defines a different interface problem between the user and machine which may have some solution by using Virtual Reality. Even though the topics vary, at times drastically, Alan has managed to use editorial selection very well intertwining them into a reasonably coherent whole. The scope is too large for any single book to cover in any detail and as is inevitable important topics for example military and medicine have been excluded. Topics chosen range from traditional computer information database visualisation to planetary exploration to the Virtual Reality version of the music video and literacy in cyberspace.

title	Architectural Theory and Design Grammars
source	[eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
doi	https://doi.org/10.52842/conf.ecaade.1993.x.i6u
summary	The idea of artificial brains and artificial intelligence (AI) has been subject to criticism. The objection of J. Searle, for instance, which has been published in 1984 and which was partially directly addressed to one of the centres of AI, the Carnegie Mellon University in Pittsburgh, is mainly based on two points: (1) interactions between physiological and mental functions, and (2) the intentionality and context-relatedness of meaning. - With an emphasis on architectural design, this paper is about the second point, because the problem of meaning is a neuralgic point in the discussion of "artificial intelligence in design" (AID). Technical parameters are incompatible with mechanisms of meaning in any field of artistic, cultural or non-technical expression. This point, that is the relation between acts of meaning and acts of technical problem-solving and, connectedly, the relation between technological and architectural design, has been widely ignored in the discussion on AID. The development seems to be dominated by the tacit assumption that architecture can be articulated and generated purely in technical and formal terms of information processing beyond the field of architecture itself. Design and shape grammars have become a well established field in the discussion of AID, also with respect to architecture. But questions of architectural history and theory are touched on only incidentally and not sufficiently in this discussion. The problem is not, in other words, simply to include more or less unrelated cases of architecture, or architectural concepts -even if these are famous ones, such as Laugier's original hut for instance but to establish structural relations between arguments of architectural theory and arguments of AID.

summary	The colour video recording Urban Simulator in TUT was built very early compared with the development of video systems. A contract for planning the simulator electronics, mechanics and camera systems was made in january 1978 with two TUT students: Jani Granholm (computer science and engineering) and Ilkka Alavalkama (machine design and automation). Ease of control and maintenance were asked by side of ”human movement inside coloured small-scale architectural models”. From the beginning, all components of the system were carefully tested and chosen from various alternatives. Financial resources were quite limited, which lead to a long building process and to self-planned and produced mechanical and electronical elements. Some optical systems were constructed by using elements from various manufacturers.

title	An integrated system to aid the planning of concrete structures: introducing the system
source	The Int. Journal of Construction IT1(2), pp.1-14
summary	This paper reports on the development at Loughborough University of a CAD-based integrated model to aid the planning of in-situ concrete structures. The system development started after a review of the planning models currently available and after a detailed questionnaire survey undertaken amongst the top UK and US contractors on the current status of planning techniques and information technology. The main aim of this system is to automate the planning process of in-situ concrete structures using data generated by CAD systems. So far, the integration of a CAD system (AutoCAD 10) and a computerized scheduling system (Artemis 2000) has been achieved on a typical IBM-PC. This enables the generation of network plans using AutoCAD which are then automatically transferred to the Artemis system for time and cost analyses.Traditionally, construction planners are faced with many conventional drawings and documents which are used to re-extract information relevant to their planning processes. Such an approach can be very inefficient as it involves data double-handling and is often error prone. In addition, current computerized construction planning applications are little more than the automation of manual formulations of plans. For example, data are fed into the planning system and computations are performed using either CPM (Critical Path Method) or PERT (Programme Evaluation and Review Technique). However, data relating to the planning process such as activity lists, resources requirements and durations are not automatically generated within the system. It would thus seem logical to devise a CAD-based integrated planning model which accepts data in its electronic format and involves some integration of the traditional planning approach. This paper introduces the proposed CAD-based integrated planning model and describes its different components. In addition, it discusses the system functional specifications and summarizes the main benefits and limitations of such a model.

summary	The Olympus Optical Company of Japan was formed in 1919, with the introduction of the first generation single lens reflects camera, and soon after with the first microscope. Since that time, the organisation has developed and is now split into three main divisions: manufacturing and supplying cameras, microscopes and endoscopes. Other smaller specialist divisions exist suppling such products as dictaphones. Perhaps, rather surprisingly, the endoscope division is the largest part of the organisation. Through a world-wide organisation of four main business centers, Olympus Industrial, the name given to the industrial endoscope division, provides service and support to its customers. Each of the main business centers operates through agents and distributors. There are many different industries which gain the benefits of saved time and money provided by using endoscopes. To meet the needs of so many varied industries, there is a need to have a wide range of equipment. This includes light sources, to provide illumination, rigid borescopes, flexible fiberscopes, if views around corners are needed, and the new technology videoscopes. These instruments use the latest CCD technology with a small chip situated in the distal end of the scope, instead of fiberoptic image bundles used in fiberscopes.

title	Thonet Chairs Design Grammar: a Step Towards the Mass Customization of Furniture
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 181-200.
summary	The paper presents the first phase of research currently under development that is focused on encoding Thonet design style into a generative design system using a shape grammar. The ultimate goal of the work is the design and production of customizable chairs using computer assisted tools, establishing a feasible practical model of the paradigm of mass customization (Davis, 1987). The current research step encompasses the following three steps: (1) codification of the rules describing Thonet design style into a shape grammar; (2) implementing the grammar into a computer tool as parametric design; and (3) rapid prototyping of customized chair designs within the style. Future phases will address the transformation of the Thonet’s grammar to create a new style and the production of real chair designs in this style using computer aided manufacturing. Beginning in the 1830’s, Austrian furniture designer Michael Thonet began experimenting with forming steam beech, in order to produce lighter furniture using fewer components, when compared with the standards of the time. Using the same construction principles and standardized elements, Thonet produced different chairs designs with a strong formal resemblance, creating his own design language. The kit assembly principle, the reduced number of elements, industrial efficiency, and the modular approach to furniture design as a system of interchangeable elements that may be used to assemble different objects enable him to become a pioneer of mass production (Noblet, 1993). The most paradigmatic example of the described vision of furniture design is the chair No. 14 produced in 1858, composed of six structural elements. Due to its simplicity, lightness, ability to be stored in flat and cubic packaging for individual of collective transportation, respectively, No. 14 became one of the most sold chairs worldwide, and it is still in production nowadays. Iconic examples of mass production are formally studied to provide insights to mass customization studies. The study of the shape grammar for the generation of Thonet chairs aimed to ensure rules that would make possible the reproduction of the selected corpus, as well as allow for the generation of new chairs within the developed grammar. Due to the wide variety of Thonet chairs, six chairs were randomly chosen to infer the grammar and then this was fine tuned by checking whether it could account for the generation of other designs not in the original corpus. Shape grammars (Stiny and Gips, 1972) have been used with sucesss both in the analysis as in the synthesis of designs at different scales, from product design to building and urban design. In particular, the use of shape grammars has been efficient in the characterization of objects’ styles and in the generation of new designs within the analyzed style, and it makes design rules amenable to computers implementation (Duarte, 2005). The literature includes one other example of a grammar for chair design by Knight (1980). In the second step of the current research phase, the outlined shape grammar was implemented into a computer program, to assist the designer in conceiving and producing customized chairs using a digital design process. This implementation was developed in Catia by converting the grammar into an equivalent parametric design model. In the third phase, physical models of existing and new chair designs were produced using rapid prototyping. The paper describes the grammar, its computer implementation as a parametric model, and the rapid prototyping of physical models. The generative potential of the proposed digital process is discussed in the context of enabling the mass customization of furniture. The role of the furniture designer in the new paradigm and ideas for further work also are discussed.

title	Leading Indicators of CAD Experience

summary	Current interfaces and help facilities of CAD systems are not designed to respond to a user's performance. To develop such adaptive environments, a better understanding of the indicators of CAD experience is required. This paper discusses the results of studying behavior patterns of different types and levels of CAD users for a specific drawing task. The results show that the type and experience of the CAD user has a clear correlation to the pattern of commands used, the time taken, and the quality of drawing produced. By using the experimental data to train a neural network, the paper demonstrates a connectionist approach for experience assessment. This information, it is proposed, can provide input to an adaptive interface which generates unobtrusive interception to improve the performance of a CAD user. Future experiments to explore the issues of generality and interception are presented.

summary	Beginning in 1993, small groups of students of architectural design at different institutions around the world participated in collaborative design projects using a variety of tools, including CAD, Internet and teleconferencing. This programme, known as the "Virtual Design Studio" (VDS), allows students to work collectively with colleagues from different cultures and climates who are thousands of kilometres and in different time zones. Most recently, in February 1994, four institutions in N. America, one in Europe, and one in S E Asia participated in VDS’94. This paper explains the operation of the VDS and explores the future of the VDS as a potential tool for architectural design education. In particular, we review what we have learned in employing computer tools to extend the teaching in design studios into a "virtual" experience.

title	Solid Modelling by Low-cost Hardware and Software: The Crystal Palace's Node
source	[eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
doi	https://doi.org/10.52842/conf.ecaade.1993.x.m6j
summary	This paper describes the approach to the solid modelling by low-cost hardware and software, developed by a workgroup composed by staff members, young researchers and students of the University of Naples - Faculty of Architecture. The work was born in need of exposing to the students the project of Crystal Palace, designed in 1850 by J. Paxton, and used in the Italian universities as an example of first prefabrication by components and the organization of the yard. Using commercial programs and the students' computers, we had done a 3D model of the Crystal Palace's structural node, making an interesting experience based on the cooperation between university structures and private resources.
