title The Art of Computer Graphics Programming: Translating Pioneer Programs

summary Considering the importance of the use of programming languages for teaching computational design to architects, this paper proposes the translation of computer programs from a pioneer work in this field into a more contemporary programming language. The book The Art of Computer Graphics Programming: A Structured Introduction for Architects and Designers was published in 1987 by William J. Mitchell, Robin Ligget and Thomas Kvan, and remains an important reference for architects. The original Pascal codes in the book were translated into Processing, and made available through an Internet website, along with images and comments, in order to give late Prof. Mitchell’s work the consideration it deserves.

summary The objective of this paper is to compare the computational concepts present in three books published by Mitchell between 1987 and 1990: The art of computer-graphics programming (1987), which has Robin Liggett and Thomas Kvan as co-authors, The logic of architecture (1990), probably his most influential work, and The poetics of gardens (1988), which has Charles Moore and William Turnbull as coauthors. By looking at the concepts that are presented in the three books and establishing a comparison between them, we expect to show that The poetics of Gardens should not be seen as a detour from Mitchell´s line of research, but rather as a key piece for understanding the relationship between technology, meaning and logic in his very coherent body of work.

title BEYOND ANALYSIS AND REPRESENTATION IN CAD: A NEW COMPUTATIONAL APPROACH TO DESIGN EDUCATION
source Submitted to the Department of Architecture in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the field of Architecture: Design & Computation at the Massachusetts Institute of Technology
summary This thesis aims at changing students' attitude towards the use of computer-aided design (CAD) in architecture. It starts from the premise that CAD is used mostly for analysis and representation, and not as a real design aide, and that architecture students have a bias against learning computer programming. For this purpose, a prototypical instruction system that mixes computer-aided design and computational design theory was developed, based on a series of fundamental concepts that are common to both fields. This system was influenced by Mitchell's (1987) The Art of Computer Graphics Programming and Stiny's (1976) shape grammars. Despite being based on solid theoretical foundations, CAD has progressively become an exclusively practical tool, since its origins in the 50's and 60's, while computational design theories have been mostly restricted to the academic circles. This thesis proposes an inversion in the present situation: the study of CAD theory, and the application of computational design into practice. The system proposed provides a conceptual framework that can be adapted to different circumstances, including course formats and resources, as well as students' background and technical training. It is based on seven fundamental concepts from computational design theories that are also important to the study of shape grammars: symmetry, recursion, rule-based compositions, parameterization of shapes, generative systems, algorithmization of design procedures, and shape emergence. These concepts are introduced within a CAD context, where their practical implementation and experimentation are possible, focusing the understanding of the computational nature of design. During this research, the proposed system was tested in two case studies with students from schools that had contrary orientations in terms of the importance of CAD in the architectural curriculum. In these experimental courses, students' activities evolved from using a commercial CAD tool in an innovative way, to the use of programming techniques for creating meaningful tools. Despite not having a statistical reach, the fieldwork allowed drawing preliminary conclusions about the proposed system's efficacy, since virtually all the students reported changing their understanding of the role of CAD in architecture, while some also acknowledged a conceptual influence in other subjects and in the way they see architecture.

title How Many Ways Can You Draw a Circle?
source IEEE Computer Graphics and Applications. August, 1987. vol. 7: pp. 39-65
summary This is a first in a series of columns on computer graphics. In this column the author discusses the different algorithms one can find for drawing circles. The algorithms collection can be categorized by the two types of output: line endpoints or pixel coordinates. This comes from the general dichotomy of curve representation - parametric vs. algebraic. The language used is a mishmash of several programming constructs

title Sophisticated Image Rendering in Environmental Design Review Graphics Systems
source Proceedings of ACM CHI+GI'87 Conference on Human Factors in Computing Systems and Graphics Interface 1987 p.211-217
summary The Landscape Architecture Programme and the Computer Systems Research Institute at the University of Toronto undertook two studies using advanced rendering tools pioneered in the areas of computer animation and graphic art. Through two professional landscape architectural design studies we explored the potential role and impact of computer simulation in the initial, more creative phases of the design work. Advanced image rendering hardware and software were used to produce high quality computer drawings of design concepts. The techniques employed in this study are unique in their application to environmental design where they dramatically improve the designer's opportunities to simulate realistic images of proposed design alternatives and to consider the visual and spatial implications of such alternatives. The case studies represented in the paper were undertaken for the National Capital Commission in Ottawa, Canada. The first project is an urban design massing study called the "Parliamentary Precinct Study" and the second project is a detailed design of the "Ceremonial Routes" in Ottawa.

title Computability of Design
source New York: Wiley & Sons
summary Computer-aided design (CAD) has promised to transform the art and science of architectural design. Yet, despite some significant achievements in the past 3 decades, it has so far failed to do so. This stimulating volume, derived from a symposium held at SUNY, Buffalo in December 1986, explores the reasons why design is so difficult to support by computational means, and what can be done to alleviate this difficulty. Written by an interdisciplinary panel of experts, it presents a varied and comprehensive view of the ways creative design processes can be modelled. The contributors do not all reach the same conclusions, which makes this book lively reading. Topics are arranged into four parts: constructing models of the design process, the computational representation of design knowledge (including spatial information and implicit design intent), methods for computing the design process as a whole (including mathematical programming, expert systems, and shape grammars), and the integration of CAD with traditional design practices.

title The Initial Start: Beginning CAADD for the Brand New Student

doi https://doi.org/10.52842/conf.acadia.1987.065
summary Described is a teaching system presently being used during the first five weeks of a first course in Computer Aided Architectural Design and Drafting (After these five weeks students spend eleven weeks actively using a 2-D drafting package and a 3-D surface modeling package).

It is the view of the author that a student can obtain much more from her or his first course in CAADD if some fundamental concepts are covered specifically and dramatically, rather than assumed or conveyed by osmosis. On the other hand, one does not want to significantly delay the teaching of he principal objective: how to use a computer as a partner in design and production. The answer to meeting these two divergent objectives is two-fold: (1) careful organization with computer based tutorials, and (2) integration of architectonic lessons during the introduction.

The objectives of he initial five weeks are (1) to demystify computers, (2) teach the fundamental concepts of computer systems relating to hardware (disks, cpu, memory, display), and software (programs, data, files), (3) illustrate programming and program design, and (4) convey the concept of discrete symbol manipulation and its relation to graphics and text.

title Near- Real-Time Control of Human Figure Models
source IEEE Computer Graphics and Applications. June, 1987. vol. 7: pp. 52-60 : ill
summary Includes bibliography. Animating human figures is one of the major problems in computer animation. A recent approach is the use of dynamic analysis to compute the movement of a human figure, given the forces and torques operating within and upon the body. One of the problems with this technique is computing the forces and torques required for particular motions: this has been called the control problem of dynamic analysis. To develop a better understanding of this problem, an interactive interface to a dynamics package has been produced. This interface, along with a collection of low-level motion processes, can be used to control the motion of a human figure model. This article describes both the user interface and the motion processes, along with experiences with this approach

title Geometric Searching In Extended CSG Models : Application to Solid Modeling and Viewing
source February, 1987. 30 p. : ill
summary In this paper, the CSG representation scheme is augmented with the 'cartesian product.' The sweep method of generating solids is encompassed by this 'Extended CSG' formalism. The point inclusion problem encountered in the area of geometric searching in computational geometry is discussed in the context to solid models represented by 'extended CSG.' A simple algorithm to solve it that has a time complexity O(n), where n is the number of primitives, is presented. Allowing for preprocessing and extra storage, a second efficient algorithm, having a time complexity O(log n), is developed. The relevance of point inclusion problem in solid modelling techniques is indicated. An extended CSG based solid modeling method is proposed. A solution to the problem of hidden line removal, that uses the faster algorithm for the point inclusion problem, is also presented in the paper

title Articulated Figure Positioning by Multiple Constraints
source IEEE Computer Graphics and Applications. June, 1987. vol. 7: pp. 28-38 : ill. Includes bibliography
summary A problem that arises in positioning an articulated figures is the solution of 3D joint positions (kinematics), when joint angles are given. If more than one such goal is to be achieved, the problem is often solved interactively by positioning or solving one component of the linkage, then adjusting another, then redoing the first, and so on. This iterative process is slow and tedious. The authors present a method that automatically solves multiple simultaneous joint position goals. The user interface offers a six-degree-of freedom input device to specify joint angles and goal positions interactively. Examples are used to demonstrate the power and efficiency of this method for key-position animation

title An Introduction to Splines for Use in Computer Graphics and Geometric Modeling
source Morgan Kaufmann Publishers, Los Altos, CA
summary The most basic output primitives in every computer graphics library are "lineSegment()" and "Polygon()", ortheir equivalents. These are, of course, sufficent in the sense that any curved line or surface can be arbitrarrily well approximated by straight line segments or planar polygons, but in many contexts that is not enough. Such approximations often require large amounts of data to obtain satifactory smoothness, and they are awkward to manipulate. Then too, even with the the most sophisticated continous shading models, polygonaltechniques can resultin visually ojectionable images. Mach bands may be apparent at the borders between adjacent polygons, and there is always a telltale angularity to polygonal silhouettes. Hence many modeling systems are augmented by circles, spheres, cylinders, etc. and allow such simple primitives to be combined to form quite complex objects.

title Requirements for Developing an Information System for Architecture
source CAAD futures ‘87 [Conference Proceedings / ISBN 0-444-42916-6] Eindhoven (The Netherlands), 20-22 May 1987, pp. 149-170
summary This paper discusses possibilities of developing new tools for architectural design. It argues that architects should meet the challenge of information technology and computer-based design techniques. One such attempt has been the first phase of the development of an architectural design information system (ADIS), also an architectural design decision support system. The system should benefit from the developments of the artificial intelligence to enable the architect to have access to information required to carry out design work. In other words: the system functions as a huge on-line electronic library of architecture, containing up-to-date architectural design information, literature, documents, etc. At the same time, the system offers necessary design aids such as computer programs for design process, drawing programs, evaluation programs, cost calculation programs, etc. The system also provides data communication between the architect and members of the design coalition team. This is found to be of vital importance in the architectural design process, because it can enable the architect to fit in changes, brought about in the project by different parties. Furthermore, they will be able, to oversee promptly the consequences of changes or decisions in a comprehensive manner. The system will offer advantages over the more commonly applied microcomputer based CAAD and IGDM (integrated graphics database management) systems, or even larger systems available to an architect. Computer programs as well as hardware change rapidly and become obsolete. Therefore, unrelenting investment pressure to up-date both software and hardware exists. The financial burden of this is heavy, in particular for smaller architectural practices (for instance an architect working for himself or herself and usually with few or no permanent staff). ADIS, as an on-line architectural design aid, is constantly up-dated by its own organisation. This task will be co-ordinated by the ADIS data- base administrator (DBA). The processing possibilities of the system are faster, therefore more complex processing tasks can be handled. Complicated large graphic data files, can be easily retrieved and manipulated by ADIS, a large system. In addition, the cost of an on-line system will be much less than any other system. The system is based on one model of the architectural design process, but will eventually contain a variety of design models, as it develops. The development of the system will be an evolutionary process, making use of its users' feed-back system. ADIS is seen as a step towards full automation of architectural design practices. Apart from being an architectural design support system, ADIS will assist the architect in his/her administrative and organisational activities.

source CAAD futures ‘87 [Conference Proceedings / ISBN 0-444-42916-6] Eindhoven (The Netherlands), 20-22 May 1987, pp. 59-69
summary In this paper we describe the dynamic process of change of computer components, computer products and user-techniques. We will refer to this process as the process of automation. In the first part we describe the structure of the process of automation. This structure consists of components and relations between these components. Some of the relations can be characterised as regularities. In the second part we briefly describe the State of the Art in CAAD. From the State of the Art and the process of automation we can extrapolate the State of the Future in CAAD. This extrapolation doesn't bring us to the future we want. The structure of the process of automation will have to change if we want future CAAD to develop towards an ideal.
