The background to this large planning exercise is sketched, the goals of our computing support plan are stated, the strategies aimed at achieving these goals are explained, and the observed outcomes from implementing these strategies are listed.
In evaluating the plan, this paper argues the position that a computer culture must take hold within the College before computer-aided design will have a truly profound effect upon pedagogy. Operationally, this means that every faculty member must have a personal computer and that every student must have free access to a microcomputer facility. Only then does the whole College adopt the new culture.
The fiscal commitment is high, but there are payoffs in of fice automation that justify the investment even in the short-term. Trivial as it seems, wordprocessing is the first step in seeding this culture. These short term payoffs help make the case for investing in the promise of long-term payoffs in superior design through computer aids.
We are left on the horns of a dilemma. The rapid response and exciting images of the computergenerated video environment suggest we are entering an era when architecture itself becomes electronic. The physical built-form recedes in importance, and may even become redundant. But we must also ask: Are we entering a post-computer age? Will we realize the potential profundity of our innate human biocomputers - to the point where we renounce the hard technology of the material for the soft technology of consciousness?
The basic idea is that of top-down design - beginning with a very abstract representation, and elaborating that, in step-by-step fashion, into a complete and detailed representation. The basic operations are real-time parametric variation of designs (using the mouse and slide bar) and substitution of objects. Essentially, then, a knowledge-base in Topdown implements a kind of parametric shape grammar.
The main applications of Topdown are in introductory teaching of CAD, and (since it provides a very quick and easy way for a user to develop detailed geometric models) to provide a uniform front-end for a variety of different applications. The shell, and some example knowledge-bases, are publicly available.
This paper discusses the principles of the Topdown Shell, the implementation of knowledge bases within it, and a variety of practical design applications.
Issue-Based Information Systems are used as a means of widening the coverage of a problem. By encouraging a greater degree of participation, particularly in the earlier phases of the process, the designer is increasing the opportunity that difficulties of his proposed solution, unseen by him, will be discovered by others. Since the problem observed by a designer can always be treated as merely a symptom of another higher-level problem, the argumentative approach also increases the likelyhood that someone will attempt to attack the problem from this point of view. Another desirable characteristic of the Issue-Based Information System is that it helps to make the design process 'transparent'. Transparency here refers tO the ability of observers as well as participants to trace back the process of decision-making.
This paper offers a description of a computer-supported IBIS (written in 'C' using the 'XWindows' user interface), including a discussion of the usefulness of IBIS in design, as well as comments on the role of the computer in IBIS implementation, and related developments in computing.
Using color is among the more difficult of traditional studio chores -- it is not difficult on a computer. The manipulation of color can be a simple task if one is given reasonable software and a good graphic computer. Once introduced to students, the techniques for coloring elements on a computer find acceptance as a design tool. Methods can be quickly found for modifying the perception of space and form through the use of colon
Modern architecture is rooted in the study of color as a generator of form. This idea permeated the teachings of its founders. Yet modernist concern for color has over time evolved into a pedagogy of space and form at the exclusion of color, so much so that the modern movement today stands accused by its detractors as being formed in many shades of grey.
Modern architecture is not grey! This paper will illustrate how, using the modern graphic computer, color may be introduced to the studio and discovered as an element of design and as the substance of architectural form giving.
The paper is divided into four parts. Part I identifies fundamental theoretical problems, contrasts the application of computation to architecture and to music, and draws upon several different areas for insight into the nature of making; Part II reviews particular architectural implications of these considerations, introduces the concept of computational composition in architecture, and presents a brief overview of important precedents; Part III proposes new goals for computer-aided architectural design and presents a framework for computational composition; finally, Part IV presents recent work directly related to the ideas presented in the previous parts and leads to the Conclusion. The appendices contain a pseudo-Prolog expression of Alvar Aalto's architectural language and notes on features of the PADL-2 solid modeler that are architecturally interesting.
