title	An Overview of the PHIDIAS II HyperCAD System
doi	https://doi.org/10.52842/conf.acadia.1994.063
source	Reconnecting [ACADIA Conference Proceedings / ISBN 1-880250-03-9] Washington University (Saint Louis / USA) 1994, pp. 63-74
summary	The PHIDIAS II HyperCAD system combines the functionality of CAD graphics, hypermedia, database management and knowledge-based computation in a single, highly integrated design environment. The CAD functionality includes both 3-D and 2-D vector graphics. The hypermedia includes support for text, raster images, video and sound. The database management enables persistent storage and interlinking of large collections of text, images, video, sound and vector graphics, i.e., thousands of vector graphic objects and drawings in a single database. Retrieval is provided both through use of "associative indexing" based on hyperlinks and through use of an advanced query language. The knowledge- based computation includes both inference and knowledgebased critiquing. A highly unusual feature of PHIDIAS II is that it implements all of its functions using only hypermedia mechanisms. Complex vector graphic drawings and objects are represented as composite hypermedia nodes. Inference and critiquing are implemented through use of what are known as virtual structures [Halasz 1988], including virtual links and virtual nodes. These nodes and links are dynamic (computed) rather than static (constant). They are defined as expressions in the same language used for queries and are computed at display time. The implementation of different kinds of functions using a common set of mechanisms makes it easy to use them in combination, thus further augmenting the system's functionality. PHIDIAS supports design by informing architects as they develop a solution's form. The idea is thus not to make the design process faster or cheaper but rather to improve the quality of the things designed. We believe that architects can create better buildings for their users if they have better information. This includes information about buildings of given types, user populations, historical and modern precedents, local site and climate conditions, the urban and natural context and its historical development, as well as local, state and federal regulations.

title	PHIDIAS II - In Support of Collaborative Design
doi	https://doi.org/10.52842/conf.acadia.1996.147
source	Design Computation: Collaboration, Reasoning, Pedagogy [ACADIA Conference Proceedings / ISBN 1-880250-05-5] Tucson (Arizona / USA) October 31 - November 2, 1996, pp. 147-154
summary	The World Wide Web in combination with Java and Virtual Reality Modeling Language (VRML) create great opportunities for collaboration by distributed design teams. To take advantage of these opportunities, we have begun to create a version of the PHIDIAS hyperCAD system (McCall, Bennett and Johnson 1994) that will support communication and collaboration among designers over the Word Wide Web. PHIDIAS is an intelligent, hypermedia-based system for computer-aided design. Our strategy is to divide PHIDIAS into two parts: 1) a client-side user interface and 2) a server-side hyperCAD database engine. The client-side interface is being implemented using Java and VRML. Implementing the PHIDIAS front-end with Java enables program code distribution via the World Wide Web. VRML provides PHIDIAS with client-side computation and display of 3D graphics.

title	Architectural Courseware - A Network Based MuItimedia System for Design Education
doi	https://doi.org/10.52842/conf.acadia.1994.147
source	Reconnecting [ACADIA Conference Proceedings / ISBN 1-880250-03-9] Washington University (Saint Louis / USA) 1994, pp. 147-150
summary	Architectural Courseware is an interactive system which allows for the creative access of a courserelated multimedia database and the interactive manipulation of that database to enhance design education. This project began as a Teaching Initiative Project supported by the Division of Undergraduate Studies of North Carolina State University, Dr. James Anderson, Dean, and has evolved over two phases. Phase One produced an interactive prototype that explored the requirements and technology of multimedia as a support tool for undergraduate education, specifically for an architecture course in the School of Design, The History of Contemporary Architecture. Phase One was well received by various members of the North Carolina State University: faculty members, the Dean of the School of Design, the directors of the Library and the Computing Center, the Associate Provost for Academic Computing, The Provost, and the Dean of Undergraduate Studies. The Dean of Undergraduate Studies was encouraged by the Associate Provost for University Computing to contribute matching funds for the support of Phase Two of the project. Phase Two focused on a functional implementation of a module of the interactive prototype that could be used by students in the Fall '94 semester to test the effectiveness of the courseware concept.

title	ArchiWAIS: A Multimedia-Based Architectural Information System for Teaching and Learning Architectural History and Theory
doi	https://doi.org/10.52842/conf.acadia.1994.161
source	Reconnecting [ACADIA Conference Proceedings / ISBN 1-880250-03-9] Washington University (Saint Louis / USA) 1994, pp. 161-169
summary	Currently, there is a debate among architectural educators regarding the use of computers in the curricula. At present, computers are used for design purposes, and there is limited use in other areas of the curricula. This paper explores an instructional tool developed specifically for the teaching and learning of architectural history and theory, and since these courses are main components of any architectural curricula, using this tool can have a great impact on architectural education in general. The tool, called ArchiWAIS, is a multimedia-based architectural information system that utilizes emerging computer technologies such as multimedia, hypermedia, and telecommunications. As a multimedia system ArchiWAIS provides effective ways of handling various architectural media-text, images, architectural drawings and diagrams, three-dimensional models, animation and sound. ArchiWAIS as a distributed hypermedia system also provides multiple ways to search multimedia databases and browse through multimedia. ArchiWAIS is a WAIS (Wide-Area Information Server) client and has access to architectural databases specially constructed for this experimental project as well as general WAIS databases. ArchiWAIS is one of two subsystems of ArchiTOUR, an educational system currently under development. While ArchiWAIS searches and collects a variety of architectural information, HyperTOUR, the other subsystem of ArchiTOUR, can be used for presenting and learning a specific subject in architectural history and theory. A future extension of ArchiTOUR will be the integration of other curricula into the system, in essence, creating a common ground among architectural courses.

title	First Drawings, Then Semantics
doi	https://doi.org/10.52842/conf.acadia.1994.013
source	Reconnecting [ACADIA Conference Proceedings / ISBN 1-880250-03-9] Washington University (Saint Louis / USA) 1994, pp. 13-26
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	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	Incorporating Guidelines Into a Case-Based Architectural Design Tool
doi	https://doi.org/10.52842/conf.acadia.1994.087
source	Reconnecting [ACADIA Conference Proceedings / ISBN 1-880250-03-9] Washington University (Saint Louis / USA) 1994, pp. 87-101
summary	This paper discusses an ongoing project called Archie, a collaboration between cognitive scientists and researchers in artificial intelligence and architecture, aimed at creating computer-based aids for conceptual design. Archie is a "case-based design aid" (CBDA): a tool that provides designers flexible access to evaluated examples of past experience that they can use in their own designs. Archie is a "clever" hypermedia database aimed at aiding conceptual design in architecture. It contains about 200 problems, responses, stories, and building descriptions derived from evaluations of six libraries and two courthouses. In this paper we provide a brief history and description of Archie and discuss some issues that have come into focus through developing and initially evaluating the system: how specific architectural case information can be organized; how users can be provided more general information about issues and building types; and how information can be indexed. In each of these we briefly discuss the current state of the system and propose some potential future directions.

title	A Hypermedia Model for Supporting Energy Design in Buildings
doi	https://doi.org/10.52842/conf.acadia.1994.039
source	Reconnecting [ACADIA Conference Proceedings / ISBN 1-880250-03-9] Washington University (Saint Louis / USA) 1994, pp. 39-49
summary	Several studies have discussed the limitations of the available CAAD tools and have proposed solutions [Brown and Novitski 1987, Brown 1990, Degelman and Kim 1988, Schuman et al 1988]. The lack of integration between the different tasks that these programs address and the design process is a major problem. Schuman et al [1988] argued that in architectural design many issues must be considered simultaneously before the synthesis of a final product can take place. Studies by Brown and Novitski [1987] and Brown [1990] discussed the difficulties involved with integrating technical considerations in the creative architectural process. One aspect of the problem is the neglect of technical factors during the initial phase of the design that, as the authors argued, results from changing the work environment and the laborious nature of the design process. Many of the current programs require the user to input a great deal of numerical values that are needed for the energy analysis. Although there are some programs that attempt to assist the user by setting default values, these programs distract the user with their extensive arrays of data. The appropriate design tool is the one that helps the user to easily view the principal components of the building design and specify their behaviors and interactions. Data abstraction and information parsimony are the key concepts in developing a successful design tool. Three different approaches for developing an appropriate CAAD tool were found in the literature. Although there are several similarities among them, each is unique in solving certain aspects of the problem. Brown and Novitski [1987] emphasize the learning factor of the tool as well as its highly graphical user interface. Degelman and Kim [1988] emphasize knowledge acquisition and the provision of simulation modules. The Windows and Daylighting Group of Lawrence Berkeley Laboratory (LBL) emphasizes the dynamic structuring of information, the intelligent linking of data, the integrity of the different issues of design and the design process, and the extensive use of images [Schuman et al 19881, these attributes incidentally define the word hypermedia. The LBL model, which uses hypermedia, seems to be the more promising direction for this type of research. However, there is still a need to establish a new model that integrates all aspects of the problem. The areas in which the present research departs from the LBL model can be listed as follows: it acknowledges the necessity of regarding the user as the center of the CAAD tool design, it develops a model that is based on one of the high level theories of human-computer interaction, and it develops a prototype tool that conforms to the model.

title	The A-Buffer, an Antialiased Hidden Surface Method
source	Proceedings of SIGGRAPH 94: Computer Graphics 18 no. 3: 103-108
summary	The A-buffer (anti-aliased, area-averaged, accumulation buffer) is a general hidden surface mechanism suited to medium scale virtual memory computers. It resolves visibility among an arbitrary collection of opaque, transparent, and intersecting objects. Using an easy to compute Fourier window (box filter), it increases the effective image resolution many times over the Z-buffer, with a moderate increase in cost. The A-buffer is incorporated into the REYES 3-D rendering system at Lucasfilm and was used successfully in the "Genesis Demo" sequence in Star Trek II.

title	DesignSpace: A Manual Interaction Environment for Computer Aided Design DEMONSTRATIONS: Virtual Reality Multimedia
source	Proceedings of ACM CHI'94 Conference on Human Factors in Computing Systems 1994 v.2 pp. 33-34
summary	DesignSpace is a computer-aided-design (CAD) system that facilitates dexterous manipulation of mechanical design representations. The system consists of an interactive simulation programmed with a seamless extended model of the designer's physical environment and driven with continuous instrumentation of the designer's physical actions. The simulation displays consistent visual and aural images of the virtual environment without occluding the designer's sensation of the physical surroundings. Developed at Stanford University's Center for Design Research (CDR), DesignSpace serves as an experimental testbed for design theory and methodology research. DesignSpace includes significant contributions from recent CDR development projects: TalkingGlove, CutPlane, VirtualHand, TeleSign, and VirtualGrasp. The current DesignSpace prototype provides modeling facility for only crude conceptual design and assembly, but can network multiple systems to share a common virtual space and arbitrate the collaborative interaction. The DesignSpace prototype employs three head-tracked rear projection images, head-coupled binaural audio, hand instrumentation, and electromagnetic position tracking.

source	Reconnecting [ACADIA Conference Proceedings / ISBN 1-880250-03-9] Washington University (Saint Louis / USA) 1994, pp. 115-132
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.

source	Reconnecting [ACADIA Conference Proceedings / ISBN 1-880250-03-9] Washington University (Saint Louis / USA) 1994, pp. 209-217
summary	The outcome of an architectural project is always contingent, dependent upon conditions or events that are not established at the outset. A university design studio does not easily replicate the state of flux which occurs as an architectural commission proceeds. In developing an architectural project, each new situation, whether it be a building code issue, an engineering issue, or a client reaction, must be viewed as an opportunity to further refine and develop the design rather than a hindrance to the outcome. In the design studio I describe in this paper, students test processes which attempt to take advantage of contingent conditions, opening up the design solutions to new possibilities. As a means to open up the design process to new possibilities, this studio introduces the computer as the primary tool for design exploration. Through the computer interface, the work speculates on the possibilities of synergism, defined as the actions of two or more substances or organisms to achieve an effect of which each is individually incapable.' Three synergetic conditions are explored: that between the designer and the computer, that between the designer with computer and designers of previous works of art or architecture, and that between two or more designers working together with the computer. The lack of a predictable result, one that may be obvious or superficial, is a positive byproduct of the synergetic and contingent circumstances under which the designs are developed.

title	Navigation in Spatial Information Environments: User Interface Design Issues for Hypertext and VR Systems Posters
source	Proceedings of the ECHT'94 European Conference on Hypermedia Technologies 1994
summary	The Information City project (presented in a poster at Hypertext 93) uses the spatial user interface metaphor of a city to organize and navigate large collections of hypertextual information. As we are used to navigate real life cities the city metaphor -- enriched with magic features -- should help to navigate information structures. A first implementation of the Information City was started in a MUD system. MUDs are networked multi-user text-adventure games which usually make use of a house / city metaphor. MUDs are conceptually similar to hypertext systems and navigational findings in those systems are therefore relevant also to hypertext. While implementing the first parts of the city research into navigation in MUDs was found necessary. This poster presents some results of this navigational study and describes how knowledge in the domains of architecture and city-planning can be used to design an easy to navigate virtual city. Highlights of the results concern magic features and collaboration. Magic features extend the spatial metaphor beyond typical properties of space. An example is the hypertext link which allows tunneling through the spatial structure. Other results concern the richness of spaces (or space-descriptions) and communication between users. It seems the chief benefit of the spatial metaphor of the city is in communication about spatial relationships of information. The findings probably are valuable in designing any information system using spatial metaphors. They are especially useful for hypertext systems realized in some virtual environment -- be it a MUD or an immerse virtual reality system.

title	A Proposal for a Framework for Business Re-engineering in Design and Realization of Artificial Environments
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	According to the Top-Down design process', this paper gives a generic and qualitative description of a Concurrent Engineering Environment, that should support the problem solving procedure in town planning and architecture in a modern quality oriented society. A system that is based on the principal of democracy might guarantee the preservation of quality in the projection and realization of artificial environments. This environment can be seen as a part of the today often discussed "digital democracy", which practically is based on a infrastructure of computers, interfaces, software systems, a network, databases and a data presentation, that is able to comprise the expectations of professionals involved in the architecture and town planning process. The paper will discuss what the role of the designer and coordinator of this computer environment looks like,in order to design, plan, build and coordinate activities for the realization of this Concurrent Environment and how several software engineers work concurrently to develop tools that guarantee a modular integration. The backbone of this environment is the definition and use of standards for data exchange. Basically those standards are derived from two domains: artifacts will be described in a product model data, while natural resources are described in spatial data. Town planning has to integrate both models. It will be discussed briefly how far the data modelling language EXPRESS of part 11 of the ISO 10303 (Express Language Reference Manual) might be useful to model GIS related problems. An example will describe how a scenario of activities, from registration of real world data to recognition of requirements of society, the definition of development plans through design(competition), lawfulness checking and construction until demolition should look like.

title	Energy Related Design Decisions Deserve Simulation Approach
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	Building energy consumption and indoor climate result from complex dynamic thermal interactions between outdoor environment, building structure, heating, ventilating and air-conditioning (HVAC) system and occupants. Apart from a few trivial relations, this reality is too complicated to be casted in simple expressions, rules or graphs. As shown in a previous paper, there are now tools available - in the form of computer simulation systems - which treat the building and plant as an integrated, dynamic system. It is argued that these can and should be used in the context of design decision support and design evaluation related to thermal energy. The paper will give ageneral overview of building energy design tools which range from simplified design tools (SDT's) to comprehensive modelling and simulation systems. It will be demonstrated why SDT's are very limited in scope and range of applicability. With respect to building energy simulation the paper will compare simplified models with comprehensive models in terms of ressource needs, applicability etc. In view of the risk involved when using SDT´s or simplified models, the paper strongly promotes the use of comprehensive tools in combination with emerging intelligent front ends. The message ofthe paper will be: let the machine do the work.

source	Reconnecting [ACADIA Conference Proceedings / ISBN 1-880250-03-9] Washington University (Saint Louis / USA) 1994, pp. 133-146
summary	Architectural designers take part in two complex cultures: a parent culture that affects their overall view of the world, and an architectural subculture that orders the details of their work. With assistance from writings in contemporary philosophy, this paper analyzes aspects of both the parent culture and the subculture as they concern design processes and media. The analysis uncovers assumptions that normally assign such processes and media to a secondary role in which they to a secondary role in which they serve only as neutral and transparent skills. By constructing a set of alternative assumptions, the paper proposes a new, primary, role for design processes and media - a role that enables them to act as intentional and substantial generators of form. These alternative assumptions challenge deeply held beliefs, but examples show that when they are employed experimentally in computer-aided design, they reveal new possibilities unique to digital processes and media.

summary	It has been said that "The beginning of architecture is empty space." (Mitchell 1990) This statement typifies a design education philosophy in which the concepts of space and form are separated and defined respectively as the negative and positive of the physical world, a world where solid objects exist and void-the mere absence of substance-is a surrounding atmospheric emptiness. Since the beginning of the nineteenth century, however, there has been an alternative concept of space as a continuum: that there is a continuously modified surface between the pressures of form and space in which the shape of the space in our lungs is directly connected to the shape of the space within which we exist. (Porter 1979). The nature of the task of representing architecture alters to reflect the state of architectural understanding at each period of time. The construction of architectural space and form represents a fundamental achievement of humans in their environment and has always involved effort and materials requiring careful planning, preparation, and forethought. In architecture there is a necessary conversion to that which is habitable, experiential, and functional from an abstraction in an entirely different medium. It is often an imperfect procedure that centers on the translation rather than the actual design. Design of the built environment is an art of distinctions within the continuum of space, for example: between solid and void, interior and exterior, light and dark, or warm and cold. It is concerned with the physical organization and articulation of space. The amount and shape of the void contained and generated by the building create the fabric and substance of the built environment. Architecture as a design discipline, therefore, can be considered as a creative expression of the coexistence of form and space on a human scale. As Frank Ching writes in Architecture: Form, Space, and Order, "These elements of form and space are the critical means of architecture. While the utilitarian concerns of function and use can be relatively short lived, and symbolic interpretations can vary from age to age, these primary elements of form and space comprise timeless and fundamental vocabulary of the architectural designer." (1979)

summary	Hypermedia designers have tried to move beyond the directed graph concept, which defines hypermedia structures as aggregations of nodes and links. A substantial body of work attempts to describe hypertexts in terms of extended or global spaces. According to this approach, nodes and links acquire meaning in relation to the space in which they are deployed. Some theory of space thus becomes essential for any advance in hypermedia design; but the type of space implied by electronic information systems, from hyperdocuments to "consensual hallucinations," requires careful analysis. Familiar metaphors drawn from physics, architecture, and everyday experience have only limited descriptive or explanatory value for this type of space. As theorists of virtual reality point out, new information systems demand an internal rather than an external perspective. This shift demands a more sophisticated approach to hypermedia space, one that accounts both for stable design properties (architectonic space) and for unforeseen outcomes, or what Winograd and Flores call "breakdowns." Following Wexelblat in cyberspace theory and Dillon, McKnight, and Richardson in hypermedia theory, we call the domain of these outcomes semantic space. In two thought experiments, or brief exercises in interface design, we attempt to reconcile these divergent notions of space within the conceptual system of hypermedia.
