title A Database Management Approach to CAD/CAM Systems Integration
source December, 1984. 13 p. : ill. includes bibliography
summary Facilitating the communication between different CAD/CAM systems is rapidly becoming an important issue, as more systems reach the market. A solution to the communication problem can be found if it is considered part of the more general problem of managing the complex information associated with the representation of physical artifacts and environments in the memory of computers, thereby accounting for the operators that are used for accessing the data as well as the data itself. Database management systems have provided powerful solutions to information management problems in a variety of disciplines and enjoy a broad and rigorous research foundation. If the techniques, methods and systems that were developed for database management could be utilized for CAD/CAM integration, they would save a considerable duplication of effort, enhance the integrity of the data, and bring to bear the results and advances that have been achieved over a long period of hard work

title Perspective Vienna – A Comparison of Planning Scenarios and Real Development
source CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary With the suspension of national boarders in unions of nations, cities and their regions gain in significance for the economic, social and cultural development. This is particularly valid for Vienna, which lies close to the eastern boarder of the European Union, which should fall with the enlargement of EU in the near future. Of prominent importance is therefore to obtain a comprehensive understanding between proposed and defined aims for an urban development, the related measures and their extent ofimplementations and their actual or real effects. This paper attempts to give a strategic analysis of the Viennese urban and traffic development programs, from 1962, 1972, 1984 and 1994, on the one hand, and the data analysis of the statistical year books beginning from 1960 until 2000, on the other. The results show that adjustments have been made not only in response to certain trends, but also to a change of philosophy of urban development. It can be seen that certain assumptions of, for example, economic and transport measures can have the opposite outcome in relation to the intended objectives. Hence, one main question remains to beanswered: How should Vienna deal with the challenges ahead, to secure and foster a sustainable development under such circumstances on a long-term basis. In this respect, some measures are given, which should make it possible to overcome successfully these challenges.

title Is Design Really Social
source International Journal of Virtual Reality, 4:1
summary There are many who will readily agree with Mitchell's assertion that "the most interesting new directions (for computer-aided design) are suggested by the growing convergence of computation and telecommunication. This allows us to treat designing not just as a technical process... but also as a social process." [Mitchell 1995]. The assumption is that design was a social process until users of computer-aided design systems were distracted into treating it as a merely technical process. Most readers will assume that this convergence must and will lead to increased communication between design participants, that better social interaction leads to be better design. The unspoken assumption appears to be that putting the participants into an environment with maximal communication channels will result in design collaboration. The tools provided, therefore, must permit the best communication and the best social interaction. We see a danger here, a pattern being repeated which may lead us into less than useful activities. As with several (popular) architectural design or modelling systems already available, however, computer system implementations all too often are poor imitations manual systems. For example, few in the field will argue with the statement that the storage of data in layers in a computer-aided drafting system is an dispensable approach. Layers derive from manual overlay drafting technology [Stitt 1984] which was regarded as an advanced (manual) production concept at the time many software engineers were specifying CAD software designs. Early implementations of CAD systems (such as RUCAPS, GDS, Computervision) avoided such data organisation, the software engineers recognising that object-based structures are more flexible, permitting greater control of data editing and display. Layer-based systems, however, are easier to implement in software, more familiar to the user and hence easier to explain, initially easier to use but more limiting for an experienced and thoughtful user, leading in the end to a lesser quality in resultant drawings and significant problems in output control (see Richens [1990], pp. 31-40 for a detailed analysis of such features and constraints). Here then we see the design for architectural software faithfully but inappropriately following manual methods. So too is there a danger of assuming that the best social interaction is that done face-to-face, therefore all collaborative design communications environments must mimic face-to-face.

title Knowledge for Designers
source Architect`s journal. England: February, 1984. vol. 179: pp. 55-58
summary The first of two articles discussing expert systems. Both design and construction are carried out within the framework of empirical rules and regulations designed more for ease of implementation and checking than scientific validity. On completion of a building, little follow up research is done on the way it is used or on the way in which the assumption made in its design are borne out in practice. This present two problems: How to make information from disparate sources easily available to designers and constructors, and how to make them aware that they need this information. This paper describes how a special type of computer programming might assist in solving these problems

title A Comparative study of protocol analysis for - Spatiality of a Text-based Cyberspace
source Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 262-266
summary Graduate Institute of Architecture, National Chiao Tung University, Hsinchu, 30050, TAIWAN The adaptation of the word cyberspace (Gibson, 1984) following the emergence of the World Wide Web Internet not only succinctly revolutionized the correlation of time and space but also poised to challenge how we view the existing spatial concept. This research tries to use protocol analysis to examine text-based cyberspace, such as bulletin board, chart rooms and so forth, and the objective of this research is to realize the spatiality of cyberspace through the cognitive point of view, and to compare the differences of the definitions and perception ways of spatiality between people with general domain and in design fields. Finally, we validate the existence of cyberspace, where the process not only allows further categorization of spatial elements concluded from the earlier study, but discover that varied backgrounds can affect how a user defines and perceives cyberspace (Strate, 1999).

title VAXstation : A General-Purpose Raster Graphics Architecture
source ACM Transactions on Graphics. January, 1984. vol. 3: pp. 70-83 : ill. includes bibliography
summary A raster graphics architecture and a raster graphics device are described. The graphics architecture is an extension of the RasterOp model and supports operations for rectangle movement, text writing, curve drawing, flood, and fill. The architecture is intended for implementation by both closely and loosely coupled display subsystems. The first implementation of the architecture is a remote raster display connected by fiber optics to a VAX minicomputer. The device contains a separate microprocessor, frame buffer, and additional local memory: it is capable of executing raster commands on operands in local memory or VAX host memory

title What is eCAADe?
source The Third European Conference on CAD in the Education of Architecture [eCAADe Conference Proceedings] Helsinki (Finnland) 20-22 September 1984.
summary The main interest of the organisation is to improve the design, teaching. The design remains the core of the professional education, while computer science can support a better understanding of the design methods. Computers should amplify the human capabilities like engines allowed to carry higher forces, radio and television enabled communication over larger distances and computers today should aid the human intellectual activities, to gain a better insight in design methodology, to investigate the design process.Design research should study more extensively how buildings behave, the integration and interaction of different disciplines which contribute to the optimization of a design and the design criteria. Computers could increase the possibility to satisfy building regulations, to access and update information, to model the design process and to understand how decisions affect the building quality (functional and economical as well as formal aspects). More effort and money should be spent on this research. The organisation has been sponsored by the EEC for bringing CAAD (Computer Aided Architectural Design) educational material at the disposal of the design teachers. The Helsinki conference is the third European meeting (after Delft 1982 and Brussels 1983) which concentrates on information and experience exchange in CAAD-education and looks for common interests and collaboration. A specific joint study program works on typical audiovisual material and lecture notes, which will be updated according to teacher's needs. A demand has been done to implement an integrated CAAD package. eCAADe focuses to integrate computer approaches across country boundaries as well as across disciplinary boundaries, as to reach a higher quality of the design education.

source Toward Expert Systems, Computers and Structures. Pergamon Press, July, 1985. vol. 20: pp. 11-15. Also published in: Advances and Trends in Structures and Dynamics edited by A. K. Noor and R. J. Hayduk
summary Pergamon Press, 1985. --- Also Published in : Proceedings of the Symposium on Advances and Trends in Structures and Dynamics, Pergamon Press, George Washington University and the National Aeronautics and Space Administration, Washington, D.C. pp. 11-15, Oct.1984. The rapid advances occurring in interactive micro-computing and computer science have provided the engineer with a powerful means of processing, storing, retrieving, and displaying data. The effective use of computer technology in engineering processes and applications is recognized by many as the key to increased individual, company, and national productivity. The implications of this observation for the academic community are clear: we must prepare our students to use computer methods and applications as part of their fundamental education. The proper tradeoff between engineering fundamentals and computer science principles and practices is changing with many of the concepts of engineering now being packaged in algorithms or on computer chips. The components of an education should include operating system fundamentals, data structures, program control and organization, algorithms, and computer architectures. It is critically important for engineering students to receive an education that teaches them these fundamentals. This paper suggests that to convey the essentials of computer science to future engineers requires, in part, the addition of computer courses to the engineering curriculum. It also requires a strengthening of the computing content of many other courses so that students come to treat the computer as a fundamental component of their work. This is a major undertaking, but new engineers graduating with advanced computing knowledge will provide potentially significant future innovations in the engineering profession

source Computer-Aided Architectural Design Futures [CAAD Futures Conference Proceedings / ISBN 0-408-05300-3] Delft (The Netherlands), 18-19 September 1985, pp. 197-199
summary At the RIBA Conference of 1981 entitled 'New Opportunities', and more recently at the 1984 ACA Annual Conference on 'Architects in Competition' there has been talk of marketing, new areas of practice, recapturing areas of practice lost to other professions, more accountability to client and public 'the decline of the mystique of the professional'. It is these issues, rather than technical advances in software and hardware, that will be the prime movers in getting computers into widespread practice in the future. In this chapter we will examine how changing attitudes in the profession might affect three practical issues in computing with which the author has been preoccupied in the past year. We will conclude by considering how, in future, early design stage computing may need to be linked to architectural theory, and, as this is a conference where we are encouraged to be outspoken, we will raise the issue of a computer-based theory of architecture.

source Computer-Aided Architectural Design Futures [CAAD Futures Conference Proceedings / ISBN 0-408-05300-3] Delft (The Netherlands), 18-19 September 1985, pp. 176-184
summary One of the things in which a small country can excel is its number of architects' offices per inhabitant. In the Netherlands this is approximately one in 6500, or twice the UK density (CBS, 1984; CICA, 1982). Of the 2150 Dutch offices, 88 per cent employ less than 10 people, which compares rather well with the British Situation. For the Netherlands it is interesting that its boom in CAD, on average an annual doubling or tripling for the next few years, is likely to coincide with a revolution in CAD itself. There is no doubt that very soon the personal and larger CAD systems will clash at supermicro-level.

source Computer-Aided Architectural Design Futures [CAAD Futures Conference Proceedings / ISBN 0-408-05300-3] Delft (The Netherlands), 18-19 September 1985, pp. 92-102
summary Three-dimensional computer visualization has intrigued both building designers and computer scientists for decades. Research and conference papers present an extensive list of existing and potential uses for threedimensional geometric data for the building industry (Baer et al., 1979). Early studies on visualization include urban planning (Rogers, 1980), treeshading simulation (Schiler and Greenberg, 1980), sun studies (Anon, 1984), finite element analysis (Proulx, 1983), and facade texture rendering (Nizzolese, 1980). With the advent of better interfaces, faster computer processing speeds and better application packages, there had been interest on the part of both researchers and practitioners in three-dimensional -models for energy analysis (Pittman and Greenberg, 1980), modelling with transparencies (Hebert, 1982), super-realistic rendering (Greenberg, 1984), visual impact (Bridges, 1983), interference clash checking (Trickett, 1980), and complex object visualization (Haward, 1984). The Division of Building Research is currently investigating the application of geometric modelling in the building delivery process using sophisticated software (Evans, 1985). The first stage of the project (Vanier, 1985), a feasibility study, deals with the aesthetics of the mode. It identifies two significant requirements for geometric modelling systems: the need for a comprehensive data structure and the requirement for realistic accuracies and tolerances. This chapter presents the results of the second phase of this geometric modelling project, which is the construction of 'working' and 'presentation' models for a building.

summary The use of parametric curves and surfaces for object modeling in computer graphics is becoming increasingly popular. There is sometimes, however, a reluctance to use them because it seems that the added power they give is more than offset by the complexity of their formulations and their computations. The purpose of this article is to clarify their meanings and uses and show how much they have in common behind the diversity of their formulations. The author discusses the properties and benefits of using the parametric Hermite, Coons, Bezier, B-spline, and Beta-spline curve and surface formulations

summary Different geometric structures are investigated in the context of discrete surface representation. It is shown that minimal representations (i.e., polyhedra) can be provided by a surface-based method using nearest neighbors structures or by a volume-based method using the Delaunay triangulation. Both approaches are compared with respect to various criteria, such as space requirements, computation time, constraints on the distribution of the points, facilities for further calculations, and agreement with the actual shape of the object

title Shade Trees
source Computer Graphics, Vol. 18, No.3, pp.223-23 1
summary Shading is an important part of computer imagery, but shaders have been based on fixed models to which all surfaces must conform. As computer imagery becomes more sophisticated, surfaces have more complex shading characteristics and thus require a less rigid shading model. This paper presents a flexible tree-structured shading model that can represent a wide range of shading characteristics. The model provides an easy means for specifying complex shading characteristics. It is also efficient because it can tailor the shading calculations to each type of surface.

title A Review of Solid Shape Modelling Based on Integrity
source Computer Aided Design March, 1984. vol. 16: pp. 66-80 : ill. includes bibliography.
summary The potential benefits of using a canonical model for representing the shapes of solid objects has led to the design and implementation of a number of geometric modelers with varying capabilities. This paper reviews the approaches taken in solid modeling by defining the well-formedness conditions which must be implemented in any modeling system. The methods for satisfying the well-formedness constraints in the various solid modeling methods are reviewed, using the concept of integrity constraints. The incorporation of integrity constraints, both explicitly and implicitly, into solid modelers are considered, with particular focus on boundary modelers. The use of integrity constraints for defining shape families and assembly families are also presented. The result is a unified view of solid shape modeling systems that enables their classification and extension into particular application areas

summary The object-oriented language TM is presented and its main features are discussed, such as attribute inheritance, extensibility, encapsulation, definition of public and private responses, and addition of responses. These features make TM attractive for expansion into a programming environment providing extensive DBMS capabilities. Since TM is conceived as a programming language for CAD, the extensions that are proposed are intended to convert TM into a programming environment and DBMS for CAD applications, providing the ability to handle molecular objects, heterogeneously formatted data and constraint management. The language has been implemented while the expansions are the subject of current research
