title	First Drawings, Then Semantics

summary	The Semantic Modeling Extension (SME) prototype implements a unique approach to integrated architectural CAD that places the drawing act first in the design process. After drawing a design idea using a computer graphic system, the designer interprets the design, providing semantic content to the graphic entities. An interpretation expresses the meaning of the design with respect to a particular issue, such as structural sufficiency, energy consumption, or requirements for egress, and provides reasoning to evaluate the design addressing that issue. A design may have many interpretations to express the multiple issues that are relevant in a design project. The designer may add or delete interpretations of the design as issues change during the course of the project. Underlying the SME prototype are the concepts of form, function and behavior. In the prototype, evaluation of a design is done by deriving behavior from the graphically represented forms and relating the behavior to stated functions or requirements. The concepts of interpretations and form, function and behavior together establish a virtual product model for design. In contrast to component based approaches to product modeling that tightly bind form representations to their behavior and function, a virtual product model allows the designer to manipulate the relations among these three descriptors of a design, and thus manipulate the semantics of the design entities. By distinguishing between the act of proposing a design by drawing the conceived form and the act of assigning meaning to the form, the virtual product model approach supports both graphic thinking for design synthesis and symbolic reasoning for design evaluation. This paper presents a scenario of the use of the SME prototype in building design; provides an analysis of the design process and computational support described in the scenario; contrasts a virtual product model approach with a component-oriented product model approach; describes the software implementation of SME; and presents implications and conclusions regarding design process and technical integration.

title	Osmose: Towards Broadening the Aesthetics of Virtual Reality
source	ACM Computer Graphics: Virtual Reality Volume 30, Number 4
summary	Osmose is an immersive virtual environment, produced by Softimage in 1994/95. One of the primary goals of Osmose was to push the expressive capabilities of existing 3D tools, to demonstrate that an alternative aesthetic and interactive sensibility is possible for real-time, interactive, 3D computer graphics. Osmose was created under the direction of Char Davies, the Director of Visual Research at Softimage. A former painter, as well as a creator of 3D computer graphic stills, Davies has a particular artistic vision which has driven the project. Davies has been striving for years to represent space as a luminous enveloping medium. This has led her from painting to 3D computer graphics, and finally into creating immersive virtual spaces. One of Davies' intentions for Osmose was to create a space that is "psychically innovating," one in which, to quote Bachelard, participants do not change "place," but change their own nature. Osmose was therefore designed to explore the potential of immersive virtual space to allow participants to shed their habitual ways of looking at (and behaving in) the world. By doing this, we hoped they would then emerge from the virtual world to experience the real world in a fresh way, reawakening a fundamental sense of their own "being-in-the-world." We hoped that this could be accomplished through the visual, aural and interactive aesthetic of the work.

title	Base de datos de la arquitectura moderna de la ciudad de Maracaibo 1920-1990 [Database of the Modern Architecture of the City of Maracaibo 1920-1990]
source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 133-139
summary	Bases de datos, Sistemas y Redes 134The purpose of this report is to present the achievements obtained in the use of the technologies of information andcommunication in the architecture, by means of the construction of a database to register the information on the modernarchitecture of the city of Maracaibo from 1920 until 1990, in reference to the constructions located in 5 of Julio, Sectorand to the most outstanding planners for its work, by means of the representation of the same ones in digital format.The objective of this investigation it was to elaborate a database for the registration of the information on the modernarchitecture in the period 1920-1990 of Maracaibo, by means of the design of an automated tool to organize the it datesrelated with the buildings, parcels and planners of the city. The investigation was carried out considering three methodologicalmoments: a) Gathering and classification of the information of the buildings and planners of the modern architectureto elaborate the databases, b) Design of the databases for the organization of the information and c) Design ofthe consultations, information, reports and the beginning menu. For the prosecution of the data files were generated inprograms attended by such computer as: AutoCAD R14 and 2000, Microsoft Word, Microsoft PowerPoint and MicrosoftAccess 2000, CorelDRAW V9.0 and Corel PHOTOPAINT V9.0.The investigation is related with the work developed in the class of Graphic Calculation II, belonging to the Departmentof Communication of the School of Architecture of the Faculty of Architecture and Design of The University of the Zulia(FADLUZ), carried out from the year 1999, using part of the obtained information of the works of the students generatedby means of the CAD systems for the representation in three dimensions of constructions with historical relevance in themodern architecture of Maracaibo, which are classified in the work of The Other City, generating different types ofisometric views, perspectives, representations photorealistics, plants and facades, among others.In what concerns to the thematic of this investigation, previous antecedents are ignored in our environment, and beingthe first time that incorporates the digital graph applied to the work carried out by the architects of “The Other City, thegenesis of the oil city of Maracaibo” carried out in the year 1994; of there the value of this research the field of thearchitecture and computer science. To point out that databases exist in the architecture field fits and of the design, alsoweb sites with information has more than enough architects and architecture works (Montagu, 1999).In The University of the Zulia, specifically in the Faculty of Architecture and Design, they have been carried out twoworks related with the thematic one of database, specifically in the years 1995 and 1996, in the first one a system wasdesigned to visualize, to classify and to analyze from the architectural point of view some historical buildings of Maracaiboand in the second an automated system of documental information was generated on the goods properties built insidethe urban area of Maracaibo. In the world environment it stands out the first database developed in Argentina, it is the database of the Modern andContemporary Architecture “Datarq 2000” elaborated by the Prof. Arturo Montagú of the University of Buenos Aires. The general objective of this work it was the use of new technologies for the prosecution in Architecture and Design (MONTAGU, Ob.cit). In the database, he intends to incorporate a complementary methodology and alternative of use of the informationthat habitually is used in the teaching of the architecture. When concluding this investigation, it was achieved: 1) analysis of projects of modern architecture, of which some form part of the historical patrimony of Maracaibo; 2) organized registrations of type text: historical, formal, space and technical data, and graph: you plant, facades, perspectives, pictures, among other, of the Moments of the Architecture of the Modernity in the city, general data and more excellent characteristics of the constructions, and general data of the Planners with their more important works, besides information on the parcels where the constructions are located, 3)construction in digital format and development of representations photorealistics of architecture projects already built. It is excellent to highlight the importance in the use of the Technologies of Information and Communication in this investigation, since it will allow to incorporate to the means digital part of the information of the modern architecturalconstructions that characterized the city of Maracaibo at the end of the XX century, and that in the last decades they have suffered changes, some of them have disappeared, destroying leaves of the modern historical patrimony of the city; therefore, the necessity arises of to register and to systematize in digital format the graphic information of those constructions. Also, to demonstrate the importance of the use of the computer and of the computer science in the representation and compression of the buildings of the modern architecture, to inclination texts, images, mapping, models in 3D and information organized in databases, and the relevance of the work from the pedagogic point of view,since it will be able to be used in the dictation of computer science classes and history in the teaching of the University studies of third level, allowing the learning with the use in new ways of transmission of the knowledge starting from the visual information on the part of the students in the elaboration of models in three dimensions or electronic scalemodels, also of the modern architecture and in a future to serve as support material for virtual recoveries of some buildings that at the present time they don’t exist or they are almost destroyed. In synthesis, the investigation will allow to know and to register the architecture of Maracaibo in this last decade, which arises under the parameters of the modernity and that through its organization and visualization in digital format, it will allow to the students, professors and interested in knowing it in a quicker and more efficient way, constituting a contribution to theteaching in the history area and calculation. Also, it can be of a lot of utility for the development of future investigation projects related with the thematic one and restoration of buildings of the modernity in Maracaibo.

title	A Functional Approach to Conceptual Modelling of Steel Structures
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	The life cycle of a steel structure can be divided into six main stages: design, detailing, manufacturing, erection, maintenance and demolition. For each stage, a different party is responsible,often using its own automation aids to assist its specific task. Since all parties operate on the same steel structure, there is a need for integration between the islands of automation. Most of the developments in this area, including ISO/STEP, are directed towards the development of conceptual models carrying all relevant information through the life cycle of the product. The conceptual models are developed following a probabilistic approach. In this approach, a conceptual model is inductively developed by analyzing and modelling empirical similarities. In this paper we explain the problems resulting from following a probabilistic modelling approach by presenting its consequences. This is illustrated by the logical product model developed in Eureka project "CIMSteel". A potential solution to these problems is proposed by presenting a functionalapproach to the development of an integrated system for design, detailing and manufacturing of steel structures. The strength of this approach is illustrated by a simple example.

title	Contributions of a Complex Object Retrieval Model to a Dynamical Architectural Design Process
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	When a new Architectural Construction Project starts, all the steps of the technical design are completely redefined. The experience gained in old projects is not easily reusable. Only personal experience of each project member is relevant. The global experience of a project is difficult to manage and to define. The designers of new project have many things to learn from previous experiences that may or not be good. The use of experiences may avoid either looking for asolution to previously resolved problems or making the same mistakes. To realise experience reuse during an architectural technical design we proposed to combine two actual research works:(i) a Dynamical Architectural Construction Process (DACP), (ii) a Complex Object Management System (COMS). The first work puts forward an original construction process based on a model that uses a geometrical definition of an architectural object to produce the constructive definition of this same object. The original features of this model are: (i) the insertion of a logic level between the volume level of an architectural object and its element level, (ii) dynamic management of the different representations of an architectural object during its technical life cycle. The COMS capabilities concern memorisation and retrieval of complex objects. The use of classicalData Management Systems to store these objects is either impossible or unusable due to data dispersion. In our approach, an architectural experience is viewed as an complex object. The COMS manages an Object Base which contains different Architectural Construction Experiences in previous projects forms. At any time during the DACP, the designer can asked the COMS to retrieve a part or a whole of a previous project that illustrates its current technical state. Thearticle presents two research projects and a study of the contribution of experience reuse in a construction process.

title	Unsupervised Dynamic Concurrent Computer-Aided Design Assistant
source	Los Angeles: UCLA
summary	The increasing capability of computer-aided architectural design systems has strengthened the role that the computer plays in the workplace. Due to the complexity of developing new techniques and research, these systems are undertaken mostly by scientists and engineers without significant architectural input (Willey, 1991). The design concept of these systems may be based on a well-defined and well-understood process, which is not yet realized in architectural design (Galle, 1994). The output of such research may not be easily adapted into the design process. Most of the techniques assume a complete understanding of the design space (Gero and Maher, 1987) (Willey, 1991). The description or construction of the design space is always time and space consuming, and the result can never be complete due to the ever-changing nature of architectural design. This research intends to initiate a solution for the above problems. The proposed system is an unsupervised-dynamic-concurrent-computer-aided-design assistant. The “unsupervised” means the learning process is not supervised by the user because it is against the designer's nature to “think-aloud” in the design studio and it also increases the work load. It is dynamic because the size of the knowledge base is constantly changing. Concurrent means that there are multiple procedures active simultaneously. This research focuses on learning the operational knowledge from an individual designer and reapplying it in future designs. A computer system for this experiment is constructed. It is capable of The preliminary result shows a positive feedback from test subjects. The purpose of this research is to suggest a potent computational frame within which future developments may flourish.

title	Environment – Urban Interface within Urban Growth
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Developments in Design & Decision Support Systems in Architecture and Urban Planning, Eindhoven: Eindhoven University of Technology, ISBN 90-6814-155-4, p. 49-62
summary	This work presents the synthesis of a model of urban growth dedicated to accomplish simulations of urban spatial dynamics, based on integrated urban and environmental factors and promoting simultaneity among external and internal growth. The city and surrounding environment are captured and modeled in computational ambient, by application of the centrality / potential model (Krafta, 1994 and 1999), with support of graph theory, cellular automata, GIS and geocomputation. The model assumes the city as a field of opportunities for obtaining income, mediated by the space, which is composed of urban and environmental attributes, that work as attractors or as resistances for the urban growth. The space configuration and the distribution of those attributes generate tensions that differentiate qualitatively and quantitatively the space, through the centrality measure (built with the support of graphs techniques), coming to provoke growth in places with larger potential of development (built with the help of techniques of CA – cellular automata). Growths above environmental thresholds are considered problems, generated and overcome in the same process of production of the urban space. Iterations of that process offer a dynamic behaviour to the model, allowing to observe the growth process along the time. The model presents several possibilities: a) urban - natural environment integration; b) internal and external growth integration; c) variety in the scale; d) GIS integration and geocomputation; e) user interface; f) calibration; g) theoretical possibilities; and h) practical possibilities.

title	The Inventor Mentor: programming Object-oriented 3D graphics with Open Inventor
source	Release 2 Addison Wesley
summary	The Inventor Mentor introduces graphics programmers and application developers to Open Inventor, an object-oriented 3D toolkit. Open Inventor is a library of objects and methods used for interactive 3D graphics. Although it is written in C++, Open Inventor also includes C bindings. For the sake of brevity, the examples included in this book are in C++. All C++ examples, as well as equivalent examples written in C, are available on-line. If you are new to the C++ language, see Appendix A, "An Introduction to Object-Oriented Programming for C Programmers," to help you understand the references to classes, subclasses, and other object-oriented concepts used throughout this book. If you are using the C application programming interface, also see Appendix B, "An Introduction to the C API." This book describes how to write applications using the Open Inventor toolkit. The Inventor Toolmaker, a companion book for the advanced programmer, describes how to create new Inventor classes and how to customize existing classes. The Inventor Mentor contains the following chapters: * Chapter 1, "Overview," provides a general description of Open Inventor concepts and classes and how Inventor relates to OpenGL and the X Window System. * Chapter 2, "An Inventor Sampler," presents a short program that creates a simple object. This program is then modified to show the use of important Inventor objects: engines, manipulators, and components. * Chapter 3, "Nodes and Groups," introduces the concept of a scene graph and shows how to create nodes and combine them into different kinds of groups. * Chapter 4, "Cameras and Lights," describes the camera nodes used to view a scene and the light nodes that provide illumination. * Chapter 5, "Shapes, Properties, and Binding," describes how to create both simple and complex shapes and how to use property nodes, including material, draw style, and lighting model nodes. Binding materials and surface normals to shape nodes is also explained. * Chapter 6, "Text," shows the use of 2D and 3D text nodes. * Chapter 7, "Textures," describes how to apply textures to the surfaces of objects in a scene. * Chapter 8, "Curves and Surfaces," explains how to use NURBS curves and surfaces. * Chapter 9, "Applying Actions," describes how operations are applied to an Inventor scene graph. Actions include OpenGL rendering, picking, calculating a bounding box, calculating a transformation matrix, writing to a file, and searching the scene graph for certain types of nodes. * Chapter 10, "Handling Events and Selection," explains how Inventor receives events from the window system. It also describes how the selection node manages a selection list and performs highlighting. * Chapter 11, "File Format," describes Inventor's interchange file format, used for reading files into Inventor, writing files out from Inventor, and data exchanges such as copy and paste. * Chapter 12, "Sensors," describes how Inventor sensors watch for certain types of events and invoke user-supplied callback functions when these events occur. * Chapter 13, "Engines," describes how you can use Inventor engines to animate parts of a scene graph, or to create interdependencies among the nodes in the graph. * Chapter 14, "Node Kits," introduces node kits, a convenient mechanism for creating groups of related Inventor nodes. Each node kit contains a catalog of nodes from which you select the desired nodes. * Chapter 15, "Draggers and Manipulators," describes how to use draggers and manipulators, which are special objects in the scene graph that respond to user events. Manipulators are nodes with field values that can be edited directly by the user. * Chapter 16, "Inventor Component Library," shows how to use Inventor's Xt components, which are program modules with a built-in user interface for changing the scene graph interactively. It also Chapter 17, "Using Inventor with OpenGL," discusses how to use Inventor with the OpenGL Library.

title	Using Post-Occupancy Evaluation To AID Reflection in ConceptualDesign: Creating a Case-Based Design Aid For Architecture
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	The design of large complex "real-world" objects such as buildings requires that the intentions of many potentially competing stakeholders be understood and reconciled. The process of conceptual design itself can be understood as a set of discourses among design team participants and between the designer and the design that gradually reveal these intentions and their relationships to design moves. Our goal is to aid this discourse by creating a Case-based Design Aid (CBDA) that provides design team participants access to specific evaluated cases of experience with previous buildings. This represents a merger of two sets of theories and methodologies: case-based reasoning (CBR) in artificial intelligence; and, post-occupancy evaluation (POE) in architectural research. In developing our CBDA, we have focused on several problems in architectural design: understanding the interactions between intentions, and making links between various modes of understanding and communication, and particularly between verbal description and visual representation. This has led to a particular way of parsing experience, and to several modes of entering and browsing the system. For instance, each case is accessible as a specific building, such as the Santa Clara County Hall of Justice, that can be explored much as an architect might browse a magazine article about the building, looking at a brief text description of the building, photos, and plans. However, each plan is annotated with "problematic situations" that are actually hypertext links into the discursive part of the program. By clicking on the button, the users reaches a "story" screen that lists the intentions of various stakeholders relevant to the problematic situation, a fuller text description of the general problematic situation with a diagram, text and diagram for a specific problematic situation as it operates in a specific building, several general design responses showing how one might respond to the problematic situations, and specific design responses from specific buildings. In addition, the user can browse the system by listing his or her interests and moving directly to stories about a given space type such as "courtroom" or issue such as "way finding." In addition, the designer can access brief synopses of key issues in a building type, for a space type, or for an issue. We are currently implementing the system on the Macintosh using Common Lisp and are focusing on libraries and courthouses as initial building types. Initial feedback from designers has been encouraging. We believe that this approach provides a useful alternative to design guidelines, that often tend to be too prescriptive, and the entirely inductive approach of many designers that may miss critical intentions.

title	The Virtual Cathedral - An Essay about CAAD, History and Structure
doi	https://doi.org/10.52842/conf.ecaade.1995.355
source	Multimedia and Architectural Disciplines [Proceedings of the 13th European Conference on Education in Computer Aided Architectural Design in Europe / ISBN 0-9523687-1-4] Palermo (Italy) 16-18 November 1995, pp. 355-360
summary	The Old Cathedral of Santa Maria in Vitoria is the most representative building of the Gothic style in the Basque Country. Built during the XIV century, it has been closed to the cult in 1994 because of the high risk of collapse that presents its structure. This closure was originated by the structural analysis that was entrusted to the University of the Basque Country in 1992. The topographic works developed in the Cathedral to elaborate the planimetry of the temple revealed that many structural elements of great importance like arches, buttresses and flying buttresses were removed, modified or added along the history of Santa Maria. The first structural analysis made in the church suggested that the huge deformations showed in the resistant elements, specially the piers, were originated by interventions made in the past. A deep historical investigation allowed us to know how the Cathedral was built and the changes executed until our days. With this information, we started the elaboration of a virtual model of the Cathedral of Santa Maria. This model was introduced into a Finite Elements Method system to study the deformations suffered in the church during its construction in the XIV century, and the intervention made later in the XV, XVI and XX centuries. The efficiency of the virtual model simulating the geometry of the Cathedral along history allowed us to detect the cause of the structural damage, that was finally found in many unfortunate interventions along time.

title	Integrated Design and Building System for the Provision of Customized Housing: the Case of Post-Earthquake Haiti
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. 247-264.
summary	The paper proposes integrated design and building systems for the provision of sustainable customized housing. It advances previous work by applying a methodology to generate these systems from vernacular precedents. The methodology is based on the use of shape grammars to derive and encode a contemporary system from the precedents. The combined set of rules can be applied to generate housing solutions tailored to specific user and site contexts. The provision of housing to shelter the population affected by the 2010 Haiti earthquake illustrates the application of the methodology. A computer implementation is currently under development in C# using the BIM platform provided by Revit. The world experiences a sharp increase in population and a strong urbanization process. These phenomena call for the development of effective means to solve the resulting housing deficit. The response of the informal sector to the problem, which relies mainly on handcrafted processes, has resulted in an increase of urban slums in many of the big cities, which lack sanitary and spatial conditions. The formal sector has produced monotonous environments based on the idea of mass production that one size fits all, which fails to meet individual and cultural needs. We propose an alternative approach in which mass customization is used to produce planed environments that possess qualities found in historical settlements. Mass customization, a new paradigm emerging due to the technological developments of the last decades, combines the economy of scale of mass production and the aesthetics and functional qualities of customization. Mass customization of housing is defined as the provision of houses that respond to the context in which they are built. The conceptual model for the mass customization of housing used departs from the idea of a housing type, which is the combined result of three systems (Habraken, 1988) -- spatial, building system, and stylistic -- and it includes a design system, a production system, and a computer system (Duarte, 2001). In previous work, this conceptual model was tested by developing a computer system for existing design and building systems (Benr__s and Duarte, 2009). The current work advances it by developing new and original design, building, and computer systems for a particular context. The urgent need to build fast in the aftermath of catastrophes quite often overrides any cultural concerns. As a result, the shelters provided in such circumstances are indistinct and impersonal. However, taking individual and cultural aspects into account might lead to a better identification of the population with their new environment, thereby minimizing the rupture caused in their lives. As the methodology to develop new housing systems is based on the idea of architectural precedents, choosing existing vernacular housing as a precedent permits the incorporation of cultural aspects and facilitates an identification of people with the new housing. In the Haiti case study, we chose as a precedent a housetype called ‚Äúgingerbread houses‚Äù, which includes a wide range of houses from wealthy to very humble ones. Although the proposed design system was inspired by these houses, it was decided to adopt a contemporary take. The methodology to devise the new type was based on two ideas: precedents and transformations in design. In architecture, the use of precedents provides designers with typical solutions for particular problems and it constitutes a departing point for a new design. In our case, the precedent is an existing housetype. It has been shown (Duarte, 2001) that a particular housetype can be encoded by a shape grammar (Stiny, 1980) forming a design system. Studies in shape grammars have shown that the evolution of one style into another can be described as the transformation of one shape grammar into another (Knight, 1994). The used methodology departs takes off from these ideas and it comprises the following steps (Duarte, 2008): (1) Selection of precedents, (2) Derivation of an archetype; (3) Listing of rules; (4) Derivation of designs; (5) Cataloguing of solutions; (6) Derivation of tailored solution.

title	Impact-Analysis of Urban Design Realtime impact-analysis models for urban designers

summary	The past five years Prof Dr Jr T.M. de Jong, professor in environmental planning and sustainability at the Technical University of Delft, has developed a theoretical foundation for the analysis of urban design on the ecological, technical, economical, cultural and political impacts of morphologic interventions on different levels of scale. From september 1994 Jr AJ. Boelen (Urban Design Scientist and Knowledge Engineer) started a research project at the same university to further explore the possibilities of these theories and to develop impact evaluation models for urban design and development with the theoretical work of De Jong as a starting point. The paper discusses the development of a design and decision support system based on these theories. For the development of this system, techniques like object-orientation, genetic algorithms and knowledge engineering are used. The user interface, the relation between the real world, paper maps and virtual maps and the presentation of design-interventions and impacts caused by the interventions are important issues. The development-process is an interactive step by step process. It consists of the making of a prototype of the system, testing the theory and hypothe-sisses the system is based on, by applying tests end adjusting the theory and hypothesisses where needed. Eventually the system must be able to act as an integrator of many different models already developed or still to be developed. The structure of the system will allow easy future expansion and adjustment to changing insights. The logic used to develop the basic theory on which this system is founded makes it possible to even introduce and maintain rather subjective aspects like quality or appraisal as impacts that can be evaluated. In a previously developed system "Momentum" this was proved to work effectively for the national level. In this project we will - amongst other things - try to prove the effectiveness of impact-evaluation for other levels of scale.

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.

summary	A design problem shared over the Internet raises issues of how digital media and group dynamics affect networked design collaborations. This paper describes how to conduct a long-distance studio and compares asynchronous and synchronous collaborative techniques. Digital methods are discussed in relationship to both the creative process and design communication. In schematic stages, less precise tools used asynchronously allow free exploration and creative misreadings, while in later stages, more direct real-time exchanges bring a project to resolution. For the final review, synchronous video-conferencing with interactive graphics allow comparison of cross-cultural differences. Used effectively, these tools can electronically create a compelling sense of place. Ways to foster a strong virtual community are discussed in an agenda for future virtual design.
