title Teddy: A Sketching Interface for 3D Freeform Design
source SIGGRAPH 99 Conference Proceedings, 109-126. ACM
summary Teddy is a sketching interface for quickly and easily design freeform models such as stuffed animals and other rotund objects. The user draws several 2D freeform strokes interactively on the screen and the system automatically constructs plausible 3D polygonal surfaces. Our system supports several modeling operations, including the operation to construct a 3D polygonal surface from a 2D silhouette drawn by the user: it inflates the region surrounded by the silhouette making wide area fat, and narrow area thin. Teddy, our prototype system, is implemented as a Java program, and the mesh construction is done in real-time on a standard PC. I will give a live demonstration of modeling operations and describe its algorithms in detail.

summary This paper describes the three generations of CAD systems. The first generation of (primarily analytical) computer programmes really aided designing. These programmes were the tools for finding a functional solution in different areas of designing, from flat plans to the space organisation of a hospital. One of the shortcomings of these programmes was the lack of graphic interface. With time, however, this kind of interface was developed. As a result of this second generation of CAD systems the computer was transformed into a drafting machine and CAD meant Computer Aided Drafting. The main thesis of this consideration is that only now we have the chance to return to the idea of Computer Aided Design. One of the examples of these trends is the AVOCAAD programme in which Added Value of CAAD is analysed. The development of the third generation of CAD systems will be possible in the near future. Aiding the process of designing will demand the elaboration of new methods of using the computer at the early stages of this process. The computer should be used not for generating variants of functional solutions only but for also for the creation of 3D forms by 3D sketching. For this, the computer should be transformed from a tool into a medium; only then will designing become true Designing in Cyber Space.

title XML for Flexibility an Extensibility of Design Information Models

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

title Esboçando com Gestos: O Projeto 3D SketchMaker (Sketching with Gestures: The 3D SketchMaker Project)
source III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 141-144
summary The 3D SketchMaker Project has developed two prototypes for a gestural 3D sketching interface in a computer system to be used in the earliest phases of the design process. The goal of this ongoing research is to provide architects, and other designers involved in object conception, with a 3D gestural instrument that takes advantage of new virtual reality resources and is more natural than using the mouse, less difficult than learning complex software and less abstract than manipulating 2D entities on orthogonal projections. The focus of this project is on the input interface, taking into consideration two factors: First, for many architects and designers, one of the main reasons for not using 3D modeling from the very beginning of the design process is that both current computer hardware and software are hardly appropriate to do the spontaneous and quick drawings that are used to assist in conceptualizing their objects. Second, three-dimensional modeling packages use two-and-three dimensional elements, in a 3D environment, but usually employ 2D input devices that are not appropriate to work in 3D environments, such as mice or pen-and-tablets. The 3D SketchMaker was conceived to take advantage of a natural tendency most people have in using gesture as an aid to language when trying to describe the shape, form or volume of objects. The system is intended to assist or replace the first 2D drawing steps in the design process, generating rough 3D sketches that can be refined later. It is, in essence, a 3D modeling system (a prototype, at this time) directed to do sketching with hand movements and gestures in a virtual reality environment.

title A digital Procedure of Building Construction: A practical project
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 earlier times in which computers have not yet been developed well, there has been some researches regarding representation using conventional media (Gombrich, 1960; Arnheim, 1970). For ancient architects, the design process was described abstractly by text (Hewitt, 1985; Cable, 1983); the process evolved from unselfconscious to conscious ways (Alexander, 1964). Till the appearance of 2D drawings, these drawings could only express abstract visual thinking and visually conceptualized vocabulary (Goldschmidt, 1999). Then with the massive use of physical models in the Renaissance, the form and space of architecture was given better precision (Millon, 1994). Researches continued their attempts to identify the nature of different design tools (Eastman and Fereshe, 1994). Simon (1981) figured out that human increasingly relies on other specialists, computational agents, and materials referred to augment their cognitive abilities. This discourse was verified by recent research on conception of design and the expression using digital technologies (McCullough, 1996; Perez-Gomez and Pelletier, 1997). While other design tools did not change as much as representation (Panofsky, 1991; Koch, 1997), the involvement of computers in conventional architecture design arouses a new design thinking of digital architecture (Liu, 1996; Krawczyk, 1997; Murray, 1997; Wertheim, 1999). The notion of the link between ideas and media is emphasized throughout various fields, such as architectural education (Radford, 2000), Internet, and restoration of historical architecture (Potier et al., 2000). Information technology is also an important tool for civil engineering projects (Choi and Ibbs, 1989). Compared with conventional design media, computers avoid some errors in the process (Zaera, 1997). However, most of the application of computers to construction is restricted to simulations in building process (Halpin, 1990). It is worth studying how to employ computer technology meaningfully to bring significant changes to concept stage during the process of building construction (Madazo, 2000; Dave, 2000) and communication (Haymaker, 2000).In architectural design, concept design was achieved through drawings and models (Mitchell, 1997), while the working drawings and even shop drawings were brewed and communicated through drawings only. However, the most effective method of shaping building elements is to build models by computer (Madrazo, 1999). With the trend of 3D visualization (Johnson and Clayton, 1998) and the difference of designing between the physical environment and virtual environment (Maher et al. 2000), we intend to study the possibilities of using digital models, in addition to drawings, as a critical media in the conceptual stage of building construction process in the near future (just as the critical role that physical models played in early design process in the Renaissance). This research is combined with two practical building projects, following the progress of construction by using digital models and animations to simulate the structural layouts of the projects. We also tried to solve the complicated and even conflicting problems in the detail and piping design process through an easily accessible and precise interface. An attempt was made to delineate the hierarchy of the elements in a single structural and constructional system, and the corresponding relations among the systems. Since building construction is often complicated and even conflicting, precision needed to complete the projects can not be based merely on 2D drawings with some imagination. The purpose of this paper is to describe all the related elements according to precision and correctness, to discuss every possibility of different thinking in design of electric-mechanical engineering, to receive feedback from the construction projects in the real world, and to compare the digital models with conventional drawings.Through the application of this research, the subtle relations between the conventional drawings and digital models can be used in the area of building construction. Moreover, a theoretical model and standard process is proposed by using conventional drawings, digital models and physical buildings. By introducing the intervention of digital media in design process of working drawings and shop drawings, there is an opportune chance to use the digital media as a prominent design tool. This study extends the use of digital model and animation from design process to construction process. However, the entire construction process involves various details and exceptions, which are not discussed in this paper. These limitations should be explored in future studies.

source International Conference on Generative Art
summary This paper is a summary of my last degree in architecture (discussed in December 1999) with Prof. Celestino Soddu and Prof. Enrica Colabella. In this work I had the possibility to reach complexity by a generative approach with the construction of a paradigm that organizes the different codes of project identity. My general objective was to design shape complexity in variable categories : 3d space surfaces, 2d drawings and 2d textures. I was to discover the identity of one of my favourite architects of the 20th century : Antoni Gaudì, by constructing codes relative to shape complexity. I defined my particular objective in the possibility to abduct from Gaudì's imaginary reference the generatives codes that operate in the logical processing I use to create a possible species project. The next step was to verify the exact working of the new generative codes by means of 3d scenaries, that are recognizable as "Antoni Gaudì specie's architecture". Whit project processing on the generative codes and not on a possible resulting shape design, I was able to organize by my general paradigm the attributes of the project's species : different shapes, different attributes (color, scale, proportion), to get to possible and different scenarys, all recognizable by the relative class codes. I chose three examples in Barcellona built during the period 1902 to 1914 : The Parco Guell, Casa Batllò and Casa Milà are the three reference sceneryes that I used to create the generative codes. In the second step I defined different codes that operate in sequence (it is defined in the paradigm) : The generatives codes are only subjective; they are one possible solution of my interpretation of Antoni Gaudì's identity. This codes operate in four differents ways : Geometrical codes for 2d shapes Geometrical codes for interface relations Spatial codes for 3d extrusion of 2d shapes Geometrical codes for 2d and 3d texturing of generated surfaces. By a stratified application of this codes I arrived at one idea for all the generative processes but many different, possible scenaryes, all recognizable in Gaudì's species. So, my final result has made possible sceneryes belonging to related species defined previously. At the end of my research I designed a project by combination : using Antoni Gaudì's generative codes on a new 3d scenary with a shape catalyst : the Frank Lloyd Wright Guggenheim Museum of New York. In this process I created a "hybrid scenary" : a new species of architectural look; a Guggenheim museum planned by Wright with a god pinch of Gaudì.

title An Interface for Sketching 3D Curves
source ACM Symposium on Interactive 3D Graphics, pp. 17-22 (April 1999). ACM SIGGRAPH. Edited by Jessica Hodgins and James D. Foley
summary The ability to specify nonplanar 3D curves is of fundamental importance in 3D modeling and animation systems. Effective techniques for specifying such curves using 2D input devices are desirable, but existing methods typically require the user to edit the curve from several viewpoints. We present a novel method for specifying 3D curves with 2D input from a single viewpoint. The user rst draws the curve as it appears from the current viewpoint, and then draws its shadow on the oor plane. The system correlates the curve with its shadow to compute the curve's 3D shape. This method is more natural than existing methods in that it leverages skills that many artists and designers have developed from work with pencil and paper.

title The right tool at the right time : investigation of freehand drawing as an interface to knowledge based design tools
source College of Architecture, Georgia Institute of Technology
summary Designers use different symbols and configurations in their drawings to explore alternatives and to communicate with each other. For example, when thinking about spatial arrangements, they draw bubble diagrams; when thinking about natural lighting, they draw a sun symbol and light rays. Given the connection between drawings and thinking, one should be able infer design intentions from a drawing and ultimately use such inferences to program a computer to understand our drawings. This dissertation reports findings from empirical studies on drawings and explores the possibility of using the computer to automatically infer designer's concerns from the drawings a designer makes. This dissertation consists of three parts: 1) a literature review of design studies, cognitive studies of drawing and computational sketch systems, and a set of pilot projects; 2) empirical studies of diagramming design intentions and a design drawing experiment; and 3) the implementation of a prototype system called Right-Tool-Right-Time. The main goal is to find out what is in design drawings that a computer program should be able to recognize and support. Experiments were conducted to study the relation between drawing conventions and the design tasks with which they are associated. It was found from the experiments that designers use certain symbols and configurations when thinking about certain design concerns. When thinking about allocating objects or spaces with a required dimensions, designers wrote down numbers beside the drawing to reason xviii about size and to calculate dimensions. When thinking about visual analysis, designers drew sight lines from a view point on a floor plan. Based on the recognition that it is possible to associate symbols and spatial arrangements in a drawing with a designer's intention, or task context, the second goal is to find out whether a computer can be programed to recognize these drawing conventions. Given an inferred intention and context, a program should be able to activate appropriate design tools automatically. For example, concerns about visual analysis can activate a visual simulation program, and number calculations can activate a calculator. The Right- Tool-Right-Time prototype program demonstrates how a freehand sketching system that infers intentions would support the automatic activation of different design tools based on a designers' drawing acts.

title A Web-centric CAD System for Collaborative Design
source Proceedings of the Eighth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-8536-5] Atlanta, 7-8 June 1999, pp. 65-79
summary Web-PHIDIAS is a hypermedia-based, intelligent CAD system that delivers both CAD functionality and design information to anyone with Web access. This system is above all designed to facilitate collaborative architectural design. It provides both private (individual) and collaborative (group) drawing and text authoring spaces, with a variety of types of authoring and viewing privileges for groups. This enables a single designer to work in privacy on one piece of a design and later "publish" it to a supervisor or a group. It also enables a group to work in privacy and later publish its work to a different or larger group. This notion of "levels of privacy/publication" is a crucial but too- often missing component of collaborative design systems. With WebPHIDIAS, all drawings are stored in a central repository accessible from the group server. This means that they are accessible from anywhere in the world to any viewer who has the required viewing and/or authoring privileges. This enables designers to access and modify stored drawings while travelling or when out on the site, even if the site is in another country. It also enables them to create new drawings and store them in the central repository from anywhere in the world. Web-PHIDIAS consists of an interactive Web-based client that serves as an interface to the PHIDIAS hypermedia server. This client, which is implemented in Java, provides basic, 2D graphical editing functionality and as well as display of 3D views. It also provides access to multimedia information useful for whatever design task is at hand. This information includes text and graphical descriptions of design precedents as well as various issues in design of a particular type of building.

summary Most Computer Aided Architectural Design software suits the engineered aspects of design quite well but is lacking as a design medium. As far as sketching is concerned, many architects still rely on traditional media such as pen and paper and scale models. This paper presents a theory concerning design media and the application of typical media aspects in a spatial sketch program. SketchBoX is conceived as an experimental 3D version of a sketchbook. It can be used for the notation of primary forms and structures in 'architectural' space. The program consists of several transparent drawing surfaces that can be placed in relation to each other and in relation to models of design or different design contexts. Thus architects and students in architecture might be able to explore more adequately the spatial configuration of the built environment and they can comment within the models of their designs. Architectural group discussions and collaborative work can be enhanced by SketchBoX because visual annotations can be made directly in relation to a 3D model. This paper describes the consequent design considerations and expected use of the SketchBoX program.

source Proceedings of the Eighth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-8536-5] Atlanta, 7-8 June 1999, pp. 227-244
summary Starting from an analysis of the current unsuitability of computers for sketching, three key requirements are identified, in particular the notion that re-drawing or over-drawing are more important than editing and tweaking. These requirements are encapsulated in the broad concept of Transparency, understood both literally and metaphorically. Two experiments in implementing aspects of Transparency are described. One subverts the Macintosh window manager to provide windows with variable transparency, so that tracing between applications becomes a practical possibility. The other implements a graphical interface that requires no on-screen palettes or sliders to control it, allowing uninterrupted concentration on the design in hand. User tests show that the tool can be learnt quickly, is engaging to use, and most importantly, has character.

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

title A CAVE-Interface in CAAD-Education?
source CAADRIA '99 [Proceedings of The Fourth Conference on Computer Aided Architectural Design Research in Asia / ISBN 7-5439-1233-3] Shanghai (China) 5-7 May 1999, pp. 313-323

summary The so called "CAVE-interface" is a very interesting and thrilling development for architects! It supports a better illusion of space by exposing almost a 270° view of a computer model than the 60° which can be viewed on an ordinary computer screen. At the Lund University we have got the possibility to experiment with a CAVE-installation, using it in research and the education of CAAD. The technique and three experiments are discribed. The possibilities are discussed and some problems and questions are put forward.

title Automation of Deck Bridge Representations
source AVOCAAD Second International Conference [AVOCAAD Conference Proceedings / ISBN 90-76101-02-07] Brussels (Belgium) 8-10 April 1999, pp. 69-79
summary The bridge deck has a apparent simple shape, but it is the result of an adequate combination of two longitudinal geometric components: the deck shape evolution along de longitudinal section the layout of the road, that acts in simultaneous over a cross section, defining the deck exact shape. A geometric modelling computer programme was developed for box girder decks, allowing the generation of cross sections along the deck, defined with correct shape and location. In the elaboration of the deck plan drawings, the geometric information of the real deck shape is required. This information is not managed in an integrated and automatic way. On the creation of these drawings, directly executed over a graphic system, the time consumed is considerable and it is easy to comet errors. This paper describes the drawing module included in the computer program refereed. The deck plan projections are obtained, in DXF format drawing files, using the geometric information obtained from 3D-deck model. Using the drawing module it is possible to generate the usual deck drawings required in bridge design process. Then, his module is a great support for the design process within its geometric design stage.

title Virtual Reality in Architectural Education: Defining Possibilities
source ACADIA Quarterly, vol. 18, no. 4, pp. 7-9
doi https://doi.org/10.52842/conf.acadia.1999.007
summary Introduction: virtual reality in architecture Virtual Reality (VR) is an emergent computer technology for full 3D-simulations, which has a natural application in the architectural work, due that activity involves the complete definition of buildings prior to its construction. Although the profession has a long tradition and expertise in the use of 2D-plans for the design of buildings, the increasing complexity of projects and social participation requires better media of representation. However, the technological promise of Virtual Reality involves many sophisticated software and hardware developments. It is based on techniques of 3D-modelling currently incorporated in the majority of drawing software used in architecture, and also there are several tools for rendering, animation and panoramic views, which provide visual realism. But other capabilities like interactivity and sense of immersion are still complex, expensive and under research. These require stereoscopic helmets, 3D pointers and trackers with complicated configurations and uncomfortable use. Most advanced installations of Virtual-Reality like CAVEs involve much hardware, building space and restrictions for users. Nevertheless, diverse developers are working in Virtual-Reality user-friendly techniques and there are many initial experiences of architectural walk-throughs showing advantages in the communication and development of designs. Then we may expect an increasing use of Virtual Reality in architecture.

title CAD Interfaces to the ARROW Manufactured Product Server
source Proceedings of the Eighth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-8536-5] Atlanta, 7-8 June 1999, pp. 1-11
summary The UK national project ARROW (Advanced Reusable Reliable Objects Warehouse) provides an Internet based framework through which it is possible to identify any of a range of manufactured products meeting specific design criteria. This open framework (based upon the IAI's IFCs) provides a mechanism for users to search for products from any participating manufacturer or supplier based both on specific attributes of a product or on any of the textual descriptions of the product. The service returns the closest matching products and allows the user to navigate to related information including manufacturer, suppliers, CAD details, VR displays, installation instructions, certificates, health and safety information, promotional information, costings, etc. ARROW also provides a toolkit to enable manufacturers and suppliers to more easily map and publish their information in the format utilised by the ARROW system. As part of the ARROW project we have examined the ability to interface from a design tool through to ARROW to automatically retrieve information required by the tool. This paper describes the API developed to allow CAD and simulation tools to communicate directly with ARROW and identify appropriate manufactured information. The demonstration system enables CAD systems to identify the closest matching manufactured product to a designed product and replacing the designed product with the details supplied by the manufacturer for the manufactured product as well as pulling through product attributes utilised by the design application. This paper provides a description of the ARROW framework and issues faced in providing information based upon standards as well as containing information not currently modelled in public standards. The paper looks at issues of enabling manufacturers and suppliers to move from their current world-view of product information to a more data-rich and user accessible information repository (even though this enables a uniform comparison across a range of manufacturer's products). Finally the paper comments on the likely way forward for ARROW like systems in providing quality information to end users.

title Computer in Creation of Architectural Form
source AVOCAAD Second International Conference [AVOCAAD Conference Proceedings / ISBN 90-76101-02-07] Brussels (Belgium) 8-10 April 1999,pp. 131-142
summary This paper considers graphic methods of presentation of ideas 'in the creation of architectural forms' and evolution of these methods, determined by the implementations of information technology. Drawings have been the main medium of expression since Leonardo da Vinci to the present-day. Graphic communication has always been treated as a main design tool, both - at the ending stage of design and at the early design stage. Implementation of computers in design doe not change this situation. The entire design process proceeds in a traditional way. While searching for the idea we use hand sketches and, after this, technical drawings are draught on a plotter, which replaces a drawing pen. Using computers at the early design stages encounters serious difficulties. The main thesis of this paper is that hardware and software inadequacy is not the problem, the problem is in the inadequacy of the design methods. This problem is to be reconceived as what a person can do with a program, rather than what is the capacity of a program. Contemporary computer techniques allow us to put an equation mark between the searching for idea, visualisation and its realisation in virtual space. This paper presents Sketching by scanning - an experimental method of using computer hardware and software for stimulating of searching of architectural's form.

summary Using a limited "kit of parts" [two 8 ft. 2x4's and one sheet of 1/2" birch plywood] students in teams of two are to design and construct an "interface" which joins the physical world to the virtual world of the web. The location for this piece of furniture [the CYBERjack] will be a local library in Okolona, Mississippi, where existing web computers are to be housed. The students modeled the design using formZ, then plotted full-size templates to be used in cutting the actual parts out of wood in the shop. The device was supposed to join the Body to the Machine. The project lasted 2 weeks and was part of a 4th year studio which participated in the ACADIA Library Competition last year.
