title	Application and evaluation of digital image techniques in close range photogrammetry
source	University of Innsbruck
summary	Most of the orthomapping techniques that are used in the present are restricted to surfaces that arise from a function of 'ground co- ordinates' z = f (x, y) , so-called 2.5D objects. Some techniques are also restricted to surfaces with kind of smooth shape or even to regular surfaces, but all of them are established to rectify images (although increasingly digitally). A new approach has been established for digital restitution and orthomapping of close range objects of almost any shape and size and with almost no restriction to images or objects. The idea of this approach is an inversion of the photographic technique and is (on the contrary to the 'rectification approach') strictly object oriented. All of the objects are regarded to be describable in their geometrical shape by a number of particular faces that can be regular or irregular but can anyway be created in a CAD environment. The data needed to get this surface can come from any photogrammetric, tachometric or other source with any particular one wants to have for the results. All the details that lie on that surface don't have to be restituted by analog or analytical point measurement but can after that be projected onto this surface from any photo, from any side and with any camera they have been taken. A 'Digital Projector' does the projection of the photos from the same positions and with the same inner orientation as of photographic camera. Using this approach any measurements of any details on the facades can be done easily. No details of the object can be neglected, none can be forgotten, no prior filtering of details has preceded this using. The full information of the original photos is available in the results. The results of the restitution can be presented in many ways. One of them is create orthoimages in any scale. Other results are any perspective or parallel view of the object. Other use of the strict 3D map-covered object for visualization (e.g. in architecture and archaeology application) is possible

title	Product Data Model for Interoperability in an Distributed Environment
source	CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 571-589
summary	This paper belongs to a suite of three interrelated papers. The two others are 'The VEGA Platform' and 'A Dynamic Product Model'. These two companion papers are also based on the VEGA project. The ESPRIT project VEGA (Virtual Enterprises using Groupware tools and distributed Architectures) has the objective to develop IT solutions enabling virtual enterprises, especially in the domain of architectural design and building engineering. VEGA shall give answers to many questions of what is needed for enabling such virtual enterprise from the IT side. The questions range from technologies for networks, communication between distributed applications, control, management of information flow to implementation and model architectures to allow distribution of information in the virtual enterprises. This paper is focused on the product model aspect of VEGA. So far modeling experts have followed a more or less centralized architecture (central or central with 4 satellites'). Is this also the architecture for the envisaged goal? What is the architecture for such a distributed model following the paradigm of modeling the , natural human' way of doing business? What is the architecture enabling most effective the filtering and translation in the communication process. Today there is some experience with 'bulk data' of the document exchange type. What is with incremental information (not data) exchange? Incremental on demand only the really needed information not a whole document. The paper is structured into three parts. First there is description of the modeling history or background. the second a vision of interoperability in an distributed environment from the users coming from architectural design and building engineering view point. Third is a description of work undertaken by the authors in previous project forming the direct basis for the VEGA model. Finally a short description of the VEGA project, especially the VEGA model architecture.

title	Design Evaluation Based on Virtual Representation of Spaces
source	Design and Representation [ACADIA ‘97 Conference Proceedings / ISBN 1-880250-06-3] Cincinatti, Ohio (USA) 3-5 October 1997, pp. 111-120
doi	https://doi.org/10.52842/conf.acadia.1997.111
summary	When spaces are evaluated, clients and architects often discuss design proposals by looking down at scale models. This overhead perspective forces viewers to imagine themselves looking and moving about within the model. Misperceptions may well result from such a point of view. With the advancement in virtual reality (VR) technology, and with its rising popularity in architecture, it is becoming plausible to consider using VR to evaluate design projects. The projects presented here are of three types: (1.) The first project compares people's evaluation of several slightly modified virtual models of a space. (2.) The second project compares how people evaluate a foam core model of a space to how they evaluate a virtual representation of the same space (3.) The third project compares people's evaluation of a real space to that of a virtual representation of this space. // The wide range of results presented provides one argument in support of using VR simulations to study spaces and how they are perceived. For example, results shows that a virtual window serves to alleviate perceived crowding and that added furniture serves to make a virtual room feel slightly larger and less constraining. However, problems did emerge with using virtual reality simulations to gain information about peoples' behavioral reactions to a space. Thus, not all circumstances under which VR representations are used creates valid results. Differences appear to be in the type of evaluations measured (e.g. dimensional versus behavioral). More research is needed to clarify this issue.

title	The Systematization of Information in the Computer Aided Architectural Design
source	Challenges of the Future [15th eCAADe Conference Proceedings / ISBN 0-9523687-3-0] Vienna (Austria) 17-20 September 1997
doi	https://doi.org/10.52842/conf.ecaade.1997.x.e8l
summary	Since the CAD methods were invented, the systematization of information in CAD has been strongly connected to the computerization of architect’s workshop. Nowadays, in 90., this systematization has to the great extent negative consequences. A designer understands the systematization of information through abilities and disabilities of the one, particular graphical aided documentation development system, which he deploys himself. The traditional method of design is clearly opposed to the computerized method. Data bases are seen by architects as a set of information describing particular and unique architectural project and some selected aspects correlated with narrow specialization of designer. Collaboration between participants of design process is still very challenging due to the usage of different tools and different systematization of information. It is necessary to define modern part of information in architectural design. The systematization of information should be a foundation for development of computer systems and not contrary, in this way it will be possible to overcome opposition between traditional and computerized techniques. Architect’s workshop, from the point of view of the informational structure of ongoing information exchange processes, should in greater part relay on the experience of structural analysis used for development of information systems in business. Effective utilization of computer methods requires the extension of collaboration between all the participants of design process, search for active access to distributed data bases (i.e. Internet) and increase of methodological consciousness (the ability to form own design strategies, methods and structures) indispensable for development of modern CAD systems which wouldn’t be limited to a computer graphics.

title	Computer - Tool vs. Medium
source	Challenges of the Future [15th eCAADe Conference Proceedings / ISBN 0-9523687-3-0] Vienna (Austria) 17-20 September 1997
doi	https://doi.org/10.52842/conf.ecaade.1997.x.b2e
summary	We have arrived an important juncture in the history of computing in our profession: This history is long enough to reveal clear trends in the use of computing, but not long to institutionalize them. As computers peremate every area of architecture - from design and construction documents to project administration and site supervision - can “virtual practice” be far behind? In the old days, there were basically two ways of architects working. Under stress. Or under lots more stress. Over time, someone forwarded the radical motion that the job could be easier, you could actually get more work done. Architects still have been looking for ways to produce more work in less time. They need a more productive work environment. The ideal environment would integrate man and machine (computer) in total harmony. As more and more architects and firms invest more and more time, money, and effort into particular ways of using computers, these practices will become resistant to change. Now is the time to decide if computing is developing the way we think it should. Enabled and vastly accelerated by technology, and driven by imperatives for cost efficiency, flexibility, and responsiveness, work in the design sector is changing in every respect. It is stands to reason that architects must change too - on every level - not only by expanding the scope of their design concerns, but by altering design process. Very often we can read, that the recent new technologies, the availability of computers and software, imply that use of CAAD software in design office is growing enormously and computers really have changed the production of contract documents in architectural offices.

summary	Design is a complex and time consuming process. One way to simplify the design process is to use pre-build blocks for commonly known parts instead of creating them again with CAD. To give the designer an immediate 3D view of the design, designing in virtual reality is a good choice. This paper presents a virtual reality interface tool which allows a user to assemble an architecture structure from a library of pre-built blocks. The library is a distributed client-server database.

summary	The architectural design business is marked by a progressive increase in operators all cooperating towards the realization of building structures and complex infrastructures (Jenckes, 1997). This type of design implies the simultaneous activity of specialists in different fields, often working a considerable distance apart, on increasingly distributed design studies. Collaborative Architectural Design comprises a vast field of studies that embraces also these sectors and problems. To mention but a few: communication among operators in the building and design sector; design process system logic architecture; conceptual structure of the building organism; building component representation; conflict identification and management; sharing of knowledge; and also, user interface; global evaluation of solutions adopted; IT definition of objects; inter-object communication (in the IT sense). The point of view of the research is that of the designers of the architectural artefact (Simon, 1996); its focus consists of the relations among the various design operators and among the latter and the information exchanged: the Building Objects. Its primary research goal is thus the conceptual structure of the building organism for the purpose of managing conflicts and developing possible methods of resolving them.

title	Design Speech Acts. "How To Do Things with Words" in Virtual Communities
source	CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 707-717
summary	Cyberspace is language based, and so are Virtual Communities (VCs). We propose that VCs are ideal places to experience and enhance a language for design. Design in a VC can actually be performed using speech acts that in-real-life wouldn't perform any design. We call these acts 'design speech acts'. We present, as a starting point, a list of verbs which can be used in a VC for design and the implications of using these verbs to design cyberspace. We present a methodology for structuring and defining design speech acts, so that a language for design in a VC can be subsequently developed. We are developing a specific environment for a virtual community in which designers can articulate their needs and produce text-based design objects.

title	Architecture in Landscape: Integrated CAD Environments for Contextually Situated Design
source	Challenges of the Future [15th eCAADe Conference Proceedings / ISBN 0-9523687-3-0] Vienna (Austria) 17-20 September 1997
doi	https://doi.org/10.52842/conf.ecaade.1997.x.q6p
summary	This paper explores the future role of a more holistic and integrated approach to the design of architecture in landscape. Many of the design exploration and presentation techniques presently used by particular design professions do not lend themselves to an inherently collaborative design strategy. Within contemporary digital environments, there are increasing opportunities to explore and evaluate design proposals which integrate both architectural and landscape aspects. The production of integrated design solutions exploring buildings and their surrounding context is now possible through the design development of shared 3-D and 4-D virtual environments, in which buildings no longer float in space. The scope of landscape design has expanded through the application of techniques such as GIS allowing interpretations that include social, economic and environmental dimensions. In architecture, for example, object-oriented CAD environments now make it feasible to integrate conventional modelling techniques with analytical evaluations such as energy calculations and lighting simulations. These were all ambitions of architects and landscape designers in the 70s when computer power restricted the successful implementation of these ideas. Instead, the commercial trend at that time moved towards isolated specialist design tools in particular areas. Prior to recent innovations in computing, the closely related disciplines of architecture and landscape have been separated through the unnecessary development, in our view, of their own symbolic representations, and the subsequent computer applications. This has led to an unnatural separation between what were once closely related disciplines. Significant increases in the performance of computers are now making it possible to move on from symbolic representations towards more contextual and meaningful representations. For example, the application of realistic materials textures to CAD-generated building models can then be linked to energy calculations using the chosen materials. It is now possible for a tree to look like a tree, to have leaves and even to be botanicaly identifiable. The building and landscape can be rendered from a common database of digital samples taken from the real world. The complete model may be viewed in a more meaningful way either through stills or animation, or better still, through a total simulation of the lifecycle of the design proposal. The model may also be used to explore environmental/energy considerations and changes in the balance between the building and its context most immediately through the growth simulation of vegetation but also as part of a larger planning model. The Internet has a key role to play in facilitating this emerging collaborative design process. Design professionals are now able via the net to work on a shared model and to explore and test designs through the development of VRML, JAVA, whiteboarding and video conferencing. The end product may potentially be something that can be more easily viewed by the client/user. The ideas presented in this paper form the basis for the development of a dual course in landscape and architecture. This will create new teaching opportunities for exploring the design of buildings and sites through the shared development of a common computer model.

title	What do we mean by intelligent buildings?
source	Automation in Construction 6 (5-6) (1997) pp. 395-400
summary	Various common definitions of intelligent buildings are discussed. A systems view of building design is a starting point for considering business, space and building management. An intelligent building helps an organisation to fulfil its objectives by facilitating the management of these resources and thereby increasing the effectiveness and efficiency of the organisation. At an even more fundamental level intelligent buildings can cope with social and technological change and also are adaptable to human needs.

title	The ImmersaDesk and Infinity Wall projection-based virtual reality displays
source	Computer Graphics, 31(2): 46-49, May
summary	Virtual reality (VR) can be defined as interactive computer graphics that provides viewer-centered perspective, large field of view and stereo. Head-mounted displays (HMDs) and BOOMs™ achieve these features with small display screens which move with the viewer, close to the viewer's eyes. Projection-based displays, supply these characteristics by placing large, fixed screens more distant from the viewer. The Electronic Visualization Laboratory (EVL) of the University of Illinois at Chicago has specialized in projection-based VR systems. EVL's projection-based VR display, the CAVE™ premiered at the SIGGRAPH 92 conference.In this article we present two new, CAVE-derived, projection-based VR displays developed at EVL: the ImmersaDesk™ and the Infinity Wall™, a VR version of the PowerWall. We describe the different requirements which led to their design, and compare these systems to other VR devices.

title	Evaluating Office Buildings with MOLCA(Model for Office Life Cycle Assessment)
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	MOLCA (Model for Office Life Cycle Assessment) is a project that aims to develop a tool that enables designers and builders to evaluate the environmental impact of their designs (of office buildings) from a environmental point of view. The model used is based on guidelinesgiven by ISO 14000, using the so-called Life Cycle Assessment (LCA) method. The MOLCA project started in 1997 and will be finished in 2001 resulting in the aforementioned tool. MOLCA is a module within broader research conducted at the Eindhoven University of Technology aiming to reduce design risks to a minimum in the early design stages.Since the MOLCA project started two major case-studies have been carried out. One into the difference in environmental load caused by using concrete and steel roof systems respectively and the role of recycling. The second study focused on biases in LCA data and how to handle them. For the simulations a computer-model named SimaPro was used, using the world-wide accepted method developed by CML (Centre for the Environment, Leiden, the Netherlands). With this model different life-cycle scenarios were studied and evaluated. Based on those two case studies and a third one into an office area, a first model has been developed.Bottle-neck in this field of study is estimating average recycling and re-use percentages of the total flow of material waste in the building sector and collecting reliable process data. Another problem within LCA studies is estimating the reliability of the input data and modelling uncertainties. All these topics will be subject of further analysis.

title	Sketch that Scene for Me: Creating Virtual Worlds by Freehand Drawing

doi	https://doi.org/10.52842/conf.ecaade.2000.265
summary	With the Web people can now view virtual threedimensional worlds and explore virtual space. Increasingly, novice users are interested in creating 3D Web sites. Virtual Reality Modeling Language gained ISO status in 1997, although it is being supplanted by the compatible Java3D API and alternative 3D Web technologies compete. Viewing VRML scenes is relatively straightforward on most hardware platforms and browsers, but currently there are only two ways to create 3D virtual scenes: One is to code the scene directly using VRML. The other is to use existing CAD and modeling software, and save the world in VRML format or convert to VRML from some other format. Both methods are time consuming, cumbersome, and have steep learning curves. Pen-based user interfaces, on the other hand, are for many an easy and intuitive method for graphics input. Not only are people familiar with the look and feel of paper and pencil, novice users also find it less intimidating to draw what they want, where they want it instead of using a complicated tool palette and pull-down menus. Architects and designers use sketches as a primary tool to generate design ideas and to explore alternatives, and numerous computer-based interfaces have played on the concept of "sketch". However, we restrict the notion of sketch to freehand drawing, which we believe helps people to think, to envision, and to recognize properties of the objects with which they are working. SKETCH employs a pen interface to create three-dimensional models, but it uses a simple language of gestures to control a three-dimensional modeler; it does not attempt to interpret freehand drawings. In contrast, our support of 3D world creation using freehand drawing depend on users’ traditional understanding of a floor plan representation. Igarashi et al. used a pen interface to drive browsing in a 3D world, by projecting the user’s marks on the ground plane in the virtual world. Our Sketch-3D project extends this approach, investigating an interface that allows direct interpretation of the drawing marks (what you draw is what you get) and serves as a rapid prototyping tool for creating 3D virtual scenes.

title	PCIS: a piece-based construction information system on the world wide web
source	Automation in Construction 6 (4) (1997) pp. 287-298
summary	This paper describes a piece-based construction information system organized as a hypergraphic virtual environment on the World Wide Web. An array of cubes on the site's animated splash-page acts as a directory to a collection of data-theaters that give this information its virtual form. A mouse click on one of these cubes leads to an orthographic model of the object to be constructed. This model is an index to a database of scaled drawings, animations, and specifications. The index is hypergraphic because a click on the image of one of the pieces of the model leads to a data page that provides information about that piece in the context of its assembly. Panels surround the index to act as an interface to projections of the pieces of the object. These projections include elevations, plans, slices, and dimensioned details. A click on the elevation-panel leads to information on finishes, framing, and construction of each face of the object. From above, the plan-panel shows roofing, framing, floor plan, foundation layout, excavation, and utilities as an animation of the construction process. There are also animated slice-panels that cut through the object to give heights and materials. A click on one of these panels leads to two-dimensional drawings and details of the actual construction. The orthographic index morphs to a framed VR environment where the model can be turned and viewed in perspective. A click on one of the pieces of the model in this information the VR environment leads to specifications and manufacturing information about the materials of its construction. The user accesses this information through a tool-palette to communicate with design team members. In this way, the team can coordinate the document's development, review progress, and make changes to the information system. This breaks the notion of a construction document as an object-of-exchange and suggests the use of the computer as a medium of communication that facilitates the design and construction process.

title	ARCHITECTURAL GRAPHICS: TRADITIONAL AND DIGITAL COMMUNICATION
source	Prentice Hall (ISBN: 0-13-341967)
summary	The media used to create architectural drawings are now more varied than ever before. Basic principles of drawing types, from two-dimensional orthographic projections (plans, elevations, etc.) to perspective to axonometrics are media independent. While "what the images are" may be constant, the way in which they are created and modified is, at time, media dependent and therefore variable. Because we can only modify what we create, the way an image or model is created (and therefore the media employed) affects its future uses and possibilities. Architectural Graphics is written from the point of view of today's architects - one who must be comfortable working in a variety of media. A variety of diagrams, photos, and simple drawings combine with well-executed finished samples to illustrate the basic principles of graphic communication, as well as the specific characteristics of both traditional and digital media.

title	Collaboration and Coordination in Architectural Design: approaches to computer mediated team work
source	TeamCAD 97, 17-23
summary	In 1993 and 1994, instructors and students of architecture at several universities around the world* collaborated briefly on two "virtual design studio" projects. Using off-the-shelf technology of the time-email, CU-See-Me internet video, international conference calls, and exchange of CAD drawings, images, and Quicktime animations-this ambitious project explored the possibility of bringing together diverse members of an international design team together to collaborate on a short term (two week) project. Central to the "Virtual Design Studio" was a 'digital pinup board', an area where participating designers could post and view drawings and textual comments; video links and email exchange provided the media for direct communication media about designs. A report on the project [21] makes clear that the process was not without technical difficulties: a significant amount of communication concerned scheduling and coordinating file formats; disappointingly little was devoted to discussions of design issues. Although it's clear that many of the minor technical problems that inevitably plague a forward-looking effort like the Virtual Design Studio will be solved in the near term, the project also reveals the need for research on software and design practices to make computer mediated design collaboration realize its attractive promise.

summary	Many virtual-reality displays augment the user’s view of the real world but do not completely mask it out or replace it. Intuitive control and realistic interaction with these displays depend on accurate hand-eye coordination: the projected image of a 3-D cursor in virtual space should align visually with the real position of the 3-D input device that controls it. This paper discusses some of the considerations and presents algorithms for coordinating the physical and virtual worlds.

summary	ARMILLA5 is a generic computer aided design system, which supports the cooperative design of complex buildings (such as labs, offices or schools) over multiple levels of abstraction. It follows the metaphor of a virtual building site. The designers and engineers meet at a spatial location on the Internet and prepare the building construction by simulating the building site. This article describes the three essential components of the ARMILLA5-model: the geometric model which describes the spatial and physical aspects of the building site, the semantic model which implements passive building components as objects and active building components as applets or applications, and the planning model, which organizes the work steps of the individual engineers and their cooperation. The model is described using different software prototypes written in Objective C, CAD systems and HTML/JAVA.

summary	This paper addresses CAAD from an organizational point of view. We employ recent developments in organizational economics to model the organizational processes in building design. Based on an analysis of (i) the cost of transferring knowledge, and (ii) agency cost in existing design organizations, we propose a framework for redesigning organizational processes and for developing appropriate design information systems. The paper describes work on a larger ongoing research project at the Harvard Design School on intra- and interorganizational design information systems.
