title Simplification of objects rendered by polygonal approximations
source Computers and Graphics, 15(2):175-184
summary Current technology provides a means to obtain sampled data that digitally describes three-dimensional surfaces and objects. Three-dimensional digitizing cameras can be used to obtain sampled data that maps the surface of three dimensional figures and models. Data obtained from such sources enable accurate renderings of the original surface. However, the digitizing process often provides much more data than is needed to accurately recreate the surface or object. In order to use such data in real-time visual simulators, a significant reduction in the data needed to accurately render the sampled surfaces is required. The techniques presented were developed to drastically reduce the number of data points required to depict an object without sacrificing the detail and accuracy inherent in the digitizing process.

title Computer Aided Conformance Checking
source Computer Integrated Future, CIB W78 Seminar. September, 1991
summary Unnumbered : ill. includes bibliography. In the building process a number of problems exist with regard to building regulations, causing the conformance checking process to be an island in the building process. This paper discusses an approach that enables us to perform computer aided conformance checking and to integrate the conformance checking process in the building process. The approach is based on the use of product models. This paper discusses theoretical as well as implementation aspects

title Static and Dynamic Analysis of Structures, with an emphasis on mechanics and computer methods
source Kluwer Academic Pub., Dordrecht
summary This book is concerned with the static and dynamic analysis of structures. Specifically, it uses the stiffness formulated matrix methods for use on computers to tackle some of the fundamental problems facing engineers in structural mechanics. This is done by covering the Mechanics of Structures, its rephrasing in terms of the Matrix Methods and then their Computational implementation, all within a cohesive setting. Although the book is designed primarily as a text for use at the upper-graduate and beginning graduate level, many practising structural engineers will find it useful as a reference and self-study guide. Each chapter is supplemented with a collection of pertinent problems that indicate extensions of the theory and the applications. These problems, combined with selected references to relevant literature, can form the basis for further study. The book sets as its goal the treatment of structural dynamics starting with the basic mechanics and going all the way to their implementation on digital computers. Rather than discuss particular commercial packages, Professor Doyle has developed STADYN: a complete (but lean) program to perform each of the standard procedures used in commercial programs. Each module in the program is reasonably complete in itself, and all were written with the sole aim of clarity plus a modicum of efficiency, compactness and elegance.

summary The computer approaches to the discipline of project near the fifties, with the idea that all the systems and processes can be object of mathematical simulation. However in the last times, the computers were used more in drawings than in the projects, “CADrafting is uncommon (...) and CADesign is almost nonexistent...” (STEVEN, 1991). At the same time it happened a surprising approach with to architecture schools. It stimulated more methodological approaches, and the subject moved, placing the computer as element transformer. The computers have really been changing the production and generation of documents, but the question is if it has been altering the method or process of elaboration of ideas. After so much search in direction to the computers it is time of thinking what was gotten with them and the problems that accompanies him. The work search to discuss the subjects where the computer influences in the learning and the students’ development.

title THE FULL-SCALE MODEL WORKSHOP
source Proceedings of the 3rd European Full-Scale Modelling Conference / ISBN 91-7740044-5 / Lund (Sweden) 13-16 September 1990, pp. 10-11
summary The workshop is an institution, available for use by the public and established at the Laboratory of Housing in the Art Academy's school of Architecture for a 3 year trial period beginning April 1985. This resumé contains brief descriptions of a variety of representative model projects and an overview of all projects carried out so far, including the pilot projects from 1983 and planned projects to and including January 1987. The Full Scale Model Workshop builds full size models of buildings, rooms and parts of buildings. The purpose of the Full Scale Model Workshop is to promote communication among building's users. The workshop is a tool in an attempt to build bridges between theory and practice in research, experimentation and communication of research results. New ideas and experiments of various sorts can be tried out cheaply, quickly and efficiently through the building of full scale models. Changes can be done on the spot as a planned part of the project and on the basis of ideas and experiments achieved through the model work itself. Buildings and their space can thus be communicated directly to all involved persons, regardless of technical background or training in evaluation of building projects.

title Integrated Design and Sustainable Building
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary In the international student-project "European Environmental Campus 91 TU Delft Dordrecht" 20 students from 13 European countries worked in september 1991, during three weeks on "EcologicalSketches for the Island of Dordrecht". They worked on four different scales: the region isle of Dordt / the district Stadspolders / the neighbourhood I the house and the block. The environmentaltheme's Energy, Water, Traffic & Noise, Landscape & Soil were together with spatial analyses combined with the different scales. This combination was organised following the scheme mentioned below. The characters stand for the students. During the first period they worked in research groups, during the last period more in design groups. For instance: student L works in the beginning with the students B, G and Q in the research group water. In the last period sheworks with K, M, N and 0 in the design group Neighbourhood. Those students worked earlier in the other research-groups and contribute now in the design-group their thematic environmental knowledge. The results were presented to the Dordrecht council, officials and press. In the next project in september and october 1993 we started earlier with the design groups. Ten Dutch and ten "Erasmus" students worked for six weeks on proposals for the Vinex location Wateringenthe Hague. Each morning they worked in the research groups each afternoon in the design groups. The research groups used the EcoDesign Tools, small applications in Excel on Apple Macintoshto quantify the environmental pressure.

source Computer Aided Architectural Design Futures: Education, Research, Applications [CAAD Futures ‘91 Conference Proceedings / ISBN 3-528-08821-4] Zürich (Switzerland), July 1991, pp. 521-534
summary A computer program is presented which generates realistic images of planned buildings embedded in their future environment through photomontage. The planar universe of conventional photomontaging is extended to three dimensions. During an interactive preprocessing step, a three- dimensional model of the building's environment is created: Geometrical data is retrieved photogrammetrically from a number of site photographs. Atmospheric parameters and the relative weights of the components of natural daylight are also retrieved from the photographs. The final image, combining the artificial model of the building and the photographs of its surroundings, is rendered by an extended ray-tracing algorithm in three-dimensional object space.

It reviews the product data modeling language EDM, then applies it to define a part of an architectural data model. Extensions are then investigated, regarding how users could integrate various design-specific packages into a uniquely configured system
summary Both extension by substituting one technology for another and by adding a new evaluation application, are considered. Data modeling allows specification of a CAD database and identification of the kind of modularization that will work and what problems may arise

title Intra-Medium and Inter-Media Constraints
source Computer Aided Architectural Design Futures: Education, Research, Applications [CAAD Futures ‘91 Conference Proceedings / ISBN 3-528-08821-4] Zürich (Switzerland), July 1991, pp. 365-380
summary Designers work with multiple representations in a variety of media to express and explore different kinds of knowledge. The advantages of multi-media in design are well- known, and exemplified by the current interest in 'hyper-media' approaches to knowledge exploration. A principal activity in working between views in one medium (e.g. plan, section and perspective drawings), or between different representations (diagrams, maps, graphs, pictures, e.g.) is extrapolating decisions made in one view or medium over to others, so that some consistency is maintained, and implications can be explored. The former kind of consistency maintenance (intra-medium) is beginning to be well understood techniques for constraint expression., satisfaction and propagation are starting to appear in 'smart CAD' systems. The latter kind of consistency maintenance inter-media.) is different, less well understood, and will require new mechanisms for constraint management and exploration. Experiments, hypotheses, and solutions in this direction will be central to any effort that seeks to explain, emulate or assist the integrative, synthetic reasoning that characterizes environmental design and planning. This paper examines some of the characteristics and advantages of intra and inter-media constraint exploration, describes a prototype "designers workstation" and some experiments in the context of landscape planning and design, and lays out some directions for development of these ideas in future computer aided design systems.

summary In 1986 the Faculty of Architecture was established in Maputo. It is financed by the Italian Ministry of Foreign Affairs and managed by a Scientific Council of the Faculty of Architecture of "Università La Sapienza" of Rome. The need to create human technical resources beeing able to work profesionally as soon as they finish their studies, made the teaching basis for lab exercises and design. The new architects (the first six students graduated in 1991), need to design and make very important decisions without any control by more experienced local technical institutions. The creation of a CAAD laboratory, and the teaching of information technologies and metodologies in architectural designing aimes to achieve a double goal: (-) to make the new architects able to manage on their own, because of the lack of qualified human resources, large quantity of data, and difficult design problems; (-) to make University, the most important scientific center in the country, an information exchange center between developped countries, and Moçambique.

title TEAnO or the computer assisted generation of manufactured aesthetic goods seen as a constrained flux of technological unconsciousness
source International Conference on Generative Art
summary TEAnO (Telematica, Elettronica, Analisi nell'Opificio) was born in Florence, in 1991, at the age of 8, being the direct consequence of years of attempts by a group of computer science professionals to use the digital computers technology to find a sustainable match among creation, generation (or re-creation) and recreation, the three basic keywords underlying the concept of “Littérature potentielle” deployed by Oulipo in France and Oplepo in Italy (see “La Littérature potentielle (Créations Re-créations Récréations) published in France by Gallimard in 1973). During the last decade, TEAnO has been involving in the generation of “artistic goods” in aesthetic domains such as literature, music, theatre and painting. In all those artefacts in the computer plays a twofold role: it is often a tool to generate the good (e.g. an editor to compose palindrome sonnets of to generate antonymic music) and, sometimes it is the medium that makes the fruition of the good possible (e.g. the generator of passages of definition literature). In that sense such artefacts can actually be considered as “manufactured” goods. A great part of such creation and re-creation work has been based upon a rather small number of generation constraints borrowed from Oulipo, deeply stressed by the use of the digital computer massive combinatory power: S+n, edge extraction, phonetic manipulation, re-writing of well known masterpieces, random generation of plots, etc. Regardless this apparently simple underlying generation mechanisms, the systematic use of computer based tools, as weel the analysis of the produced results, has been the way to highlight two findings which can significantly affect the practice of computer based generation of aesthetic goods: ? the deep structure of an aesthetic work persists even through the more “desctructive” manipulations, (such as the antonymic transformation of the melody and lyrics of a music work) and become evident as a sort of profound, earliest and distinctive constraint; ? the intensive flux of computer generated “raw” material seems to confirm and to bring to our attention the existence of what Walter Benjamin indicated as the different way in which the nature talk to a camera and to our eye, and Franco Vaccari called “technological unconsciousness”.

title Persistence of Perception: Encoding Reality
source SIGraDi 2003 - [Proceedings of the 7th Iberoamerican Congress of Digital Graphics] Rosario Argentina 5-7 november 2003
summary "Liquid architecture makes liquid cities, cities that change at the shift of value, where visitors with different backgrounds see different landmarks, where neighborhoods vary with ideas held in common, and evolve as the ideas mature or dissolve." In 1991, Marcos Novak in 'Liquid Architectures in Cyberspace' projected a future of individual and blended realities of things perceived and perceived things - a place of "fertile dreams". In the cathedral, "The dream and making were one." In the present he concludes, "Curiously the practice of architecture has become increasingly disengaged from those dreams." This paper addresses inherent limitations in today's digital technology that restrict its ability to participate in the future design of the "fertile dream." It does not address the technology required, but the requirements of the technology.

title SEED: A Software Environment to Support the Early Phases in Building Design
source Proceeding of IKM '94, Weimar, Germany, pp. 5-10
summary The SEED project intends to develop a software environment that supports the early phases in building design (Flemming et al., 1993). The goal is to provide support, in principle, for the preliminary design of buildings in all aspects that can gain from computer support. This includes using the computer not only for analysis and evaluation, but also more actively for the generation of designs, or more accurately, for the rapid generation of design representations. A major motivation for the development of SEED is to bring the results of two multi-generational research efforts focusing on `generative' design systems closer to practice: 1. LOOS/ABLOOS, a generative system for the synthesis of layouts of rectangles (Flemming et al., 1988; Flemming, 1989; Coyne and Flemming, 1990; Coyne, 1991); 2. GENESIS, a rule-based system that supports the generation of assemblies of 3-dimensional solids (Heisserman, 1991; Heisserman and Woodbury, 1993). The rapid generation of design representations can take advantage of special opportunities when it deals with a recurring building type, that is, a building type dealt with frequently by the users of the system. Design firms - from housing manufacturers to government agencies - accumulate considerable experience with recurring building types. But current CAD systems capture this experience and support its reuse only marginally. SEED intends to provide systematic support for the storing and retrieval of past solutions and their adaptation to similar problem situations. This motivation aligns aspects of SEED closely with current work in Artificial Intelligence that focuses on case-based design (see, for example, Kolodner, 1991; Domeshek and Kolodner, 1992; Hua et al., 1992).

source Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 727-734
summary I have been working on an architecture representation system in India since 1991; that markedly deviates from the need of traditional drawings as we know. Over three million square feet of work has been done that took advantage of this system as it was being developed. The system has now matured sufficiently to be put into practice as a comprehensive architectural system of practice. It takes advantage of creation of just-in-time dynamic multi-organizations that can get formed (and dismantled) over the Internet on a project to project basis. The raison d’être of the representation system is that it would expose the “source-code” (metaphorically) of any work of architecture to stakeholders, much the same way as an open-source software project exposes the internal representation to fellow developers. I believe the design of architecture must go through an “open source” process in order to produce socially responsible designs. Such a stance is explained in this paper. The paper also explains the system in detail; its mathematical basis and justifies the need for such an approach. It also explores how a collaborative practice can be put into place using the system in the context of Internet technologies.

summary The Department of Real Estate and Project Management (BMVB) of the Faculty of Architecture at the Delft University of Technology has been working closely with Professor Spiro N. Pollalis of Harvard University, Graduate School of Design in Cambridge, USA since 1991. His case-based interactive seminars about the management of the design & construction process have been highly appreciated by many generations of students. In Spring 2000, Pollalis suggested to extend the scope of his involvement by introducing a remote teaching component, the subject of his research in the last few years. As Information and Communication Technology (ICT) in the Design and Construction Industry is part of his lectures, it was appropriate to provide the students with a first hand experience on the subject. In the following experiment, the teacher would remain in his office at Harvard while the interactive work and discussion sessions with 130 students in a full lecture room would take place in Delft as planned. The consequences this experiment has had for the course, for the techniques and facilities used, how teachers and students experienced these, and which conclusions and recommendations can be made, are the topics of this paper.

title Ten problems for AI in design
source Workshop on AI in Design, IJCAI-91, un-numbered
summary Modern design research dates back to the end of the eighteenth century when French theorists attempted to describe design as a process. The notion of process in design dates back to the Roman engineer/architect/writer Vitruvius who described both process and performance aspects of designing. Since the 1940s there has been a variety of attempts to provide formal models of design ranging from prescriptive algorithmic-like descriptions through mathematical model and systems theoretic descriptions to the current paradigm based on the precepts and notions of artificial intelligence. All of these, including the current work, is primarily concerned with treating the process aspects of design.

title Spatial Knowledge Acquisition from Maps and Virtual Environments in Complex Architectural Space
source Proc. 16 th Applied Behavioral Sciences Symposium, 22-23 April, U.S. Airforce Academy, Colorado Springs, CO., 1996, 6-10
summary It has often been suggested that due to its inherent spatial nature, a virtual environment (VE) might be a powerful tool for spatial knowledge acquisition of a real environment, as opposed to the use of maps or some other two-dimensional, symbolic medium. While interesting from a psychological point of view, a study of the use of a VE in lieu of a map seems nonsensical from a practical point of view. Why would the use of a VE preclude the use of a map? The more interesting investigation would be of the value added of the VE when used with a map. If the VE could be shown to substantially improve navigation performance, then there might be a case for its use as a training tool. If not, then we have to assume that maps continue to be the best spatial knowledge acquisition tool available. An experiment was conducted at the Naval Postgraduate School to determine if the use of an interactive, three-dimensional virtual environment would enhance spatial knowledge acquisition of a complex architectural space when used in conjunction with floor plan diagrams. There has been significant interest in this research area of late. Witmer, Bailey, and Knerr (1995) showed that a VE was useful in acquiring route knowledge of a complex building. Route knowledge is defined as the procedural knowledge required to successfully traverse paths between distant locations (Golledge, 1991). Configurational (or survey) knowledge is the highest level of spatial knowledge and represents a map-like internal encoding of the environment (Thorndyke, 1980). The Witmer study could not confirm if configurational knowledge was being acquired. Also, no comparison was made to a map-only condition, which we felt is the most obvious alternative. Comparisons were made only to a real world condition and a symbolic condition where the route is presented verbally.
