title Lego Free-Form? Towards a Modularized Free-Form Construction
source T. Tidafi and T. Dorta (eds) Joining Languages Cultures and Visions: CAADFutures 2009 CD-Rom
summary Design Media is the tool designers use for concept realization (Schon and Wiggins, 1992; Liu, 1996). Design thinking of designers is deeply effected by the media they tend to use (Zevi, 1981; Liu, 1996; Lim, 2003). Historically, architecture is influenced by the design media that were available within that era (Liu, 1996; Porter and Neale, 2000; Smith, 2004). From the 2D plans first used in ancient egypt, to the 3D physical models that came about during the Renaissance period, architecture reflects the media used for design. When breakthroughs in CAD/CAM technologies were brought to the world in the twentieth century, new possibilities opened up for architects.

title Design Inquiry and Resource Allocation
source New York: John Wiley & Sons, 1992. pp. 51-65 : ill. tables. includes bibliography
summary This paper proposes that the primary role of resource allocation in design is to assist design decision makers in ordering preferences and exploring trade-offs. Most existing cost evaluation paradigms focus on assessing costs after design decisions are made. This view unnecessarily restricts the active participation of economic knowledge in design decision-making. The approach described in this research suggests that the exploration and definition of values and references should be the major focus of economic analysis within the design process. A conceptual framework for this approach is presented along with several examples that illustrate the use of this framework. Computational approaches are suggested which play a central role in clarifying preference and exploring trade-offs during design

title Working in Virtual Environments through appropriate Physical Interfaces
source Architectural Computing from Turing to 2000 [eCAADe Conference Proceedings / ISBN 0-9523687-5-7] Liverpool (UK) 15-17 September 1999, pp. 431-436
summary The work described here is aimed at contributing towards the debate and development relating to the construction of interfaces to explore buildings and their environs through virtual worlds. We describe a particular hardware and software configuration which is derived by the use of low cost games software to create the Virtual Environment. The Physical Interface responds to the work of other researchers, in this area, in particular Shaw (1994) and Vasquez de Velasco & Trigo (1997). Virtual Evironments might have the potential to be "a magical window into other worlds, from molecules to minds" (Rheingold, 1992), but what is the nature of that window? Currently it is often a translucent opening which gives a hazy and distorted (disembodied) view. And many versions of such openings are relatively expensive. We consider ways towards clearing the haze without too much expense, adapting techniques proposed by developers of low cost virtual reality systems (Hollands, 1995) for use in an architectural setting.

title Collective Design Network: Systems Thinking (Event-Pattern-Structures) and System Dynamics Modelling as a Design Concept and Strategy
source Computation: The New Realm of Architectural Design [27th eCAADe Conference Proceedings / ISBN 978-0-9541183-8-9] Istanbul (Turkey) 16-19 September 2009, pp. 533-540
summary This paper will relay the initial phase of a collaborative work within partners from the design discipline, systems engineering, and software engineering which deals with the interrelations of “network idea”, “systems thinking”, “collective design”, and “computation”. Vensim– a system dynamics modelling tool developed by Ventana Systems, Inc. in 1992 – has been used in an experimental first year design studio to engage students in systems thinking in the architectural design environment. It has been observed that this tool enabled most students to develop a multi-layered, complex and more controlled design logic and to amplify the cognitive processes at the beginning of the design education. We conclude that in order to fully realize systems thinking in the design process, new ways of integrating parametric design environments and system dynamic modelling environments needs to be investigated.

title Shape recognition in three dimensions
source Environment and Planning B: Planning and Design 19 : 585-603
summary The subshape recognition problem for three-dimensional shapes under linear transformations is considered. The problem is analysed in a series of cases, some that provide a determinate number of solutions and others that have indeterminately many solutions. Procedures for its solution for general shapes are developed. Difficulties posed by strict adherence to rational transformations are examined. As a corollary, an outline of a procedure for determining the symmetries of a shape is presented. Subject

title Discontinuity Meshing for Accurate Radiosity
source IEEE Computer Graphics & Applications, November 1992, pp.25-38
summary We discuss the problem of accurately computing the illumination of a diffuse polyhedral environment due to an area light source. We show how umbra and penumbra boundaries and other illumination details correspond to discontinuities in the radiance function and its derivatives. The shape, location, and order of these discontinuities is determined by the geometry of the light sources and obstacles in the environment. We describe an object-space algorithm that accurately reproduces the radiance across a surface by constructing a discontinuity mesh that explicitly represents various discontinuities in the radiance function as boundaries between mesh elements. A piecewise quadratic interpolant is used to approximate the radiance function, preserving the discontinuities associated with the edges in the mesh. This algorithm can be used in the framework of a progressive refinement radiosity system to solve the diffuse global illumination problem. Results produced by the new method are compared with ones obtained using a standard radiosity system.

source Digital Design Studios: Do Computers Make a Difference? [ACADIA Conference Proceedings / ISBN 1-880250-07-1] Québec City (Canada) October 22-25, 1998, pp. 44-57
summary More often than not, discussions taking place in specialised conferences dealing with computers and design tend to focus mostly on the tool itself. What the computer can do that other tools cannot, how computers might improve design and whether a new aesthetic would result from the computer; these are among the most recurrent issues addressed in those forums. But, by placing the instrument at the center of the debate, we might be distorting the nature of design. In the course KEYWORDS, carried out in the years 1992 and 1993 at the ETH Zurich, the goal was to transcend the discourses that concentrate on the computer, integrating it in a wider theoretical framework including principles of modern art and architecture. This paper presents a summary of the content and results of this course.

title A FINISHING TOUCH TO THE FULL-SCALE LABORATORY AT THE UNIVERSITY OF TECHNOLOGY IN VIENNA
source Proceedings of the 4rd European Full-Scale Modelling Conference / Lausanne (Switzerland) 9-12 September 1992, Part A, pp. 7-14
summary The development planning of the full-scale laboratory at the Vienna University of Technology was already presented to the third E.F.A. Conference in Lund (1990). Exchange of experience has greatly encouraged us to take all measures necessary for an immediate provisional operation. Working experience was of considerable significance regarding reconstruction work having repeatedly been postponed ever since 1988. This paper deals with the Vienna full-scale laboratory in its ultimate form and all the equipment designed therefore. Summarizingly, the further measures for operation are being considered.

title From Barcelona. Chronicle and Provisional Evaluation of a New Course on Architectural Solid Modelling by Computerized Means
source CAAD Instruction: The New Teaching of an Architect? [eCAADe Conference Proceedings] Barcelona (Spain) 12-14 November 1992, pp. 351-362
summary The first step made at the ETSAB in the computer field goes back to 1965, when professors Margarit and Buxade acquired an IBM computer, an electromechanical machine which used perforated cards and which was used to produce an innovative method of structural calculation. This method was incorporated in the academic courses and, at that time, this repeated question "should students learn programming?" was readily answered: the exercises required some knowledge of Fortran and every student needed this knowledge to do the exercises. This method, well known in Europe at that time, also provided a service for professional practice and marked the beginning of what is now the CC (Centro de Calculo) of our school. In 1980 the School bought a PDP1134, a computer which had 256 Kb of RAM, two disks of 5 Mb and one of lO Mb, and a multiplexor of 8 lines. Some time later the general politics of the UPC changed their course and this was related to the purchase of a VAX which is still the base of the CC and carries most of the administrative burden of the school. 1985 has probably been the first year in which we can talk of a general policy of the school directed towards computers. A report has been made that year, which includes an inquest adressed to the six Departments of the School (Graphic Expression, Projects, Structures, Construction, Composition and Urbanism) and that contains interesting data. According to the report, there were four departments which used computers in their current courses, while the two others (Projects and Composition) did not use them at all. The main user was the Department of Structures while the incidence of the remaining three was rather sporadic. The kind of problems detected in this report are very typical: lack of resources for hardware and software and for maintenance of the few computers that the school had at that moment; a demand (posed by the students) greatly exceeding the supply (computers and teachers). The main problem appeared to be the lack of computer graphic devices and proper software.

source CAAD Instruction: The New Teaching of an Architect? [eCAADe Conference Proceedings] Barcelona (Spain) 12-14 November 1992, pp. 497-510
summary The paper provides instances of graphic techniques using random numbers in layout generation and spatial modelling. Leaving aside more elaborate methods based on shape grammars and syntactically oriented schemes, direct graphic procedures useful in computer aided architectural design are discussed. Drawings presented show how aleatory input can influence the appearance of computer generated forms.

title Reint-Ops: A Tool Supporting Conceptual Design
source Mission - Method - Madness [ACADIA Conference Proceedings / ISBN 1-880250-01-2] 1992, pp. 221-232
summary Reasoning is influenced by our perception of the environment. New aspects of our environment help to provoke new thoughts. Thus, changes of what is perceived can be assumed to stimulate the generation of new ideas, as well. In CAD, computerized three-dimensional models of physical entities are produced. Their representation on the monitor is determined by our viewing position and by the rendering method used. Especially the wire-frame representations of views lend themselves to a variety of readings, due to coincident and intersecting lines. Methods by which wire-frame views can be processed to extract the shapes that they contain have been investigated and developed. The extracted shapes can be used as a base for the generation of derived entities through various operations that are called Reinterpretation Operations. They have been implemented as a prototypical extension (named Reint-Ops) to an existing modeling shell. ReintOps is a highly interactive exploratory CAD tool, which allows the user to customize criteria and factors which are used in the reinterpretation process. This tool can be regarded as having a potential to support conceptual design investigations.

title Towards the 4th Dimension
source CAAD Instruction: The New Teaching of an Architect? [eCAADe Conference Proceedings] Barcelona (Spain) 12-14 November 1992, pp. 91-100
summary Fifteenth century Europeans 'knew' that the sky was made of closed concentric crystal spheres, rotating around a central earth and carrying the stars and planets. That 'knowledge' structured everything they did and thought, because it told them the truth. Then Galileo's telescope changed the truth. As a result, a hundred years later everybody 'knew' that the universe was open and infinite, working like a giant clock. Architecture, music, literature, science, economics, art, politics - everything - changed, mirroring the new view created by the change in the knowledge. The medium by which perceptive intuition and the rigorous discipline of shaping became compatible was technology. Technelogos, the art of knowing how to make, fell naturally and historically into the realm of perceptive fundamentals... For the artist it verified scientifically what he had perceived emotionally; for the engineer it added the vast field of perceptive responses to the narrow limits of the laboratory experiment.

title Designing for Pedestrians : A CAD-Network Analysis Approach
source New York: John Wiley & Sons, 1992. pp. 379-398 : ill. includes a short bibliography
summary Microcomputer techniques have been developed that combine CAD drawings with transportation network analysis software that uses spreadsheets and stand-alone programs activated from the DOS operating system. The CAD feature simplifies and improves the methods used to design pedestrian circulation facilities and evaluate the impact of new development on existing pedestrian flows. Through the use of customized software, the need for manual data entry is reduced, and the graphical display of analysis results in most intermediate steps in the process are automated. Three hypothetical case studies are presented, concentrating on proposed pedestrian circulation improvements at Penn Station, New York

summary With the development of storage media such as the CD ROM, the availability and usage of very large data bases of information has dramatically opened new vistas for the creation of electronic libraries. From dictionaries and encyclopedias to historical treatises, the electronic packaging of large and cumbersome information sources has begun to demonstrate its utility and efficiency. Today the bridge to an unknown territory of electronic knowledge resources lies here at the boundary between the passive (though electronically accelerated) access to information through electronic books and the user interactive access to knowledge. This paper is about that boundary.

title A Computerized Fire Safety Evaluation System for Business Occupancies

summary The development of computer-based code compliance checking programs has been the focus of many studies. While some of these investigated the procedural aspects of building codes, others focused more on their rule base. On the other hand, due to the complexity of the codes, the process of identifying which sections apply to a given problem, and in which order to access them requires a meta-knowledge structuring system. National Fire Protection Association (NFPA) 101M, Alternative Approaches to Life Safety (1992) provides a framework through which code sections can be systematically accessed by means of a set of checklists. The study presented here primarily focuses on the development of a computer based fire safety code checking system called ARCHCode/Business for business occupancies following the guidelines and the methodology described in Chapter 7 of NFPA 101M.

title The Use of Graphic Data Bases in the Teaching of Geometry

summary The paper doesn't intend to provide relevant innovations in the field of processing program designs or software technology. Although I respect other opinions, I feel that the uncontested aid which using computers to teach architecture means should preferably and primarily be oriented towards searching for ways to better transmit and explain what we have, up to now, been teaching through other means.

However, the novelty and advantages of reccuring to this new instrument should not make us fall into the mistake of letting it be used as a substitute of teachers' and students' work. The computer is simply another instrument; of great potential efficacy, but nevertheless just an instrument.
