title	The gardens revisited: The link between technology, meaning and logic?
source	Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 643-652

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	On the Reasons for Designing an Object Based Language Called TM
source	1987. 7 p. : ill. includes bibliography
summary	One of the most basic problems in attempting to use computers for architectural applications has been the generation of design alternatives. In order to approach this problem, it is claimed in the paper that in reality it is two basic problems: a methodological problem and a data and procedural representation problem. Diagrammatic Production Rules (DPR's), developed previously by the author, have been proposed for dealing with methodological problem and TM, an object based language, is proposed in the paper for dealing with the data and procedural representation problem. An example of a DPR and a 'program' in TM are included to illustrate the relationship between the two

summary	A model of the design process control that supports dynamic allocation of tasks between a designer and a computer is presented. The model is discussed theoretically, and is demonstrated through a Prolog implementation for the participatory design of single family houses. Its utility and universal applicability are established, as well as its relationship to other computational approaches to design automation

title	The Quadcode and its Arithmetic
source	Communications of the ACM. July, 1987. vol. 30: pp. 621-626 : ill. includes bibliography
summary	The quadcode is a hierarchical data structure for describing digital images. It has the following properties: (1) straightforward representation of dimension, size, and the relationship between an image and its subsets; (2) explicit description of geometric properties, such as location, distance, and adjacency; and (3) ease of conversion from and to raster representation. The quadcode has applications to computer graphics and image processing because of its ability to focus on selected subsets of the data and to allow utilization of multiple resolutions in different parts of the image. A related approach is the quadtree. Samet recently presented a thorough survey of the literature in that field. Gargantini and Abel and Smith presented linear quadtrees and linear locational keys that are efficient labeling techniques for quadtrees. In those papers the geometric concepts of the image are discussed by using the tree as an interpretive medium, and the approaches and procedures are based on traversal of the nodes in the tree. In this paper the authors present the quadcode system, which is a direct description of the image, and discuss the geometric concepts in terms of the coded images themselves

title	Acquiring Expert Knowledge from Characterized Designs
source	Artificial Intelligence for Engineering Design and Manufacturing. 1987. vol. 1: pp. 73-87
summary	The expertise of designers consists primarily of information about the relationship between goals or performance criteria and the attributes of the desired artifact that will result in performances that will satisfy these criteria. Pareto optimization is discussed as a means of structuring designs on the basis of their performance. The induction algorithm ID3 is used as means of inferring general statements about the nature of solutions which exhibit Pareto optimal performance in terms of a set of performance criteria. The rules inferred in a building design domain are compared with those extracted using a heuristic based learning system

title	Natural Language Prototypes for Analyzing Design Standards
source	Southampton, U.K: Computational Mechanics Publications, 1987. pp. 147-160
summary	CADLINE has abstract only. This paper addresses the use of natural language processing for acquiring, processing, and representing knowledge from design standards. A standard is a set of provisions providing principles, models, rules, limits, and particulars that are established by some authority for some purpose. In their textual form as written documents, design standards cannot directly be used in computer-aided design (CAD) systems. This paper demonstrates how standards can be transformed, using natural language processing techniques, from their textual form to alternative representations that more readily lend themselves to use in computer-aided design systems, supporting a variety of design applications. The language being transformed is the Building Officials and Code Administrators Building Code, one set of requirements that govern the design of buildings. Prototype computer subsystems have been developed that transform natural language sentences to case-grammar format and finally to subject-relationship- object triplets. The three prototypes that achieve these transformations are described: a parser, a semantic analyzer, and a query system. During one processing cycle, the system identifies that data items in a provision and the relationships between the data items. It also interacts with the user to add new data items to its knowledge bases, to verify data items found, and to add to its vocabulary. Alternatively, it responds to natural-language questions about the contents of the standard by identifying the relevant provisions within the standards. Processing formal documents requires knowledge about vocabulary, word-order, time, semantics, reference, and discourse. Despite the relative clarity of formal writing as it occurs in standards, the difficulties of implied responsibility, multiple meanings, and implied data items remain. A long-term research program at North Carolina State University has been defined that builds on these prototypes to further investigate knowledge acquisition and representation for standards

title	Visualization Needs and Tool Kits

summary	A well-known Finnish novel characterizes the agrarian way of life by the following words: In the beginning there was a marsh, a hoe and John. John turned the marsh into a fertile corn field by means of the Finnish "sisu" or perseverance. We may draw a parallel to architectural design and say that in the beginning there was the idea of the architect only after that came various tools. Nevertheless, the method of visualization - image in its many forms - is something quintessential in architectural planning and design: it plays a central role as a tool for the designer's own thinking and evaluation, in general communication of planning, and in the communication between the designer and other parties of the planning process. Different sketches give directly visual interpretations to different consequences. The needs for the communication of planning in itself have grown along with the manifold development of public communication. Accordingly, the communication of planning has to compete with the highly-developed commercial communication.

title	The Perceived Impact of Computers on the Teaching of Design Goals and Reality
source	Integrating Computers into the Architectural Curriculum [ACADIA Conference Proceedings] Raleigh (North Carolina / USA) 1987, pp. 135-152
doi	https://doi.org/10.52842/conf.acadia.1987.135
summary	The actual and potential impact of computers on design education is an issue of growing concern for students, faculty, and practitioners. The assessment ranges from very positive to negative. (On first sight, the complexity of reasons for and against computers in design seems overwhelming. This paper attempts to isolate reasons for the various attitudes and find a method to judge the impact of computers on design education rationally by identifying goals and comparing them to reality. Part One establishes facts: the human and financial investment that universities have made in CAD, based on results from publications and a national ACADIA survey, and the investment of architectural firms in CAD, based on recent national and regional in-depth studies. Part Two examines goals of the use of CAD in the design studio. For better analysis, goals are divided into two extreme categories: tool independent and tool dependent. Tool independent goals are born out of the need to improve the existing design education, independent from technological development. Tool dependent goals are tailored to the alleged capabilities of new software and hardware and to pressure from the professional community. The actual definition of goals for design education will lie somewhere in between. Part three examines the reality in the design studio. It tries to determine the place of the computer in the design process from a student's view, and an educator's view. The last section is dedicated to the testing of the developed theory against actual studios.

title	VizAbility
source	PWS Publishing, San Francisco
summary	The handbook provides you with a broad conceptual overview of visual thinking by guiding you through the interactive experiences of VizAbility(tm). It parallels the structure of the CD-ROM, providing a context for your reflections and comments on these experiences and for analysis of their implications. Although the VizAbility(tm) Handbook can be read on its own and still provide valuable insight, it is designed to interact with the VizAbility(tm) CD-ROM. The intent is to integrate the three components so as to encourage you to move fluidly between the different media to explore, experience, and extend your visual abilities.

title	THE FULL-SCALE LABORATORY IN LUND
source	Proceedings of the 1st European Full-Scale Workshop Conference / ISBN 87-88373-20-7 / Copenhagen (Denmark) 15-16 January 1987, pp. 7-17
summary	An often repeated statement of the nature of the result of our general construction activities in general says that any building and environmental arrangement could be seen as a pure experimental product. The building, in this sense, is nothing but one single full-scale experiment started afresh each time, unfortunately, we could add, without the consistent follow-up measures. In view of this way of understanding the building process you might deduce the interest in a more anticipating attitude.and behaviour, namely the mock-up method or the full-scale design process, based on the philosophy that in a situation of uncertainty you had better try before than after. An underlying presumption is, however, that generally there is a lack of knowledge about the consequences by transferring spatial and design ideas from. drawings to one to one realization. A lack of knowledge not only-among lay, people but also among professionals. The mock-up practice can also to the same extent be derived from a pure investigative interest with the aim to virtually analyze general or specific problems in the* relationship man and the built environment, particularly buildings and spatial settings on the micro level. That means the use of the full-scale method for the search for basic design knowledge. In this sense the mock-up activities started in Sweden.

title	A Hypermedia Model for Supporting Energy Design in Buildings
source	Reconnecting [ACADIA Conference Proceedings / ISBN 1-880250-03-9] Washington University (Saint Louis / USA) 1994, pp. 39-49
doi	https://doi.org/10.52842/conf.acadia.1994.039
summary	Several studies have discussed the limitations of the available CAAD tools and have proposed solutions [Brown and Novitski 1987, Brown 1990, Degelman and Kim 1988, Schuman et al 1988]. The lack of integration between the different tasks that these programs address and the design process is a major problem. Schuman et al [1988] argued that in architectural design many issues must be considered simultaneously before the synthesis of a final product can take place. Studies by Brown and Novitski [1987] and Brown [1990] discussed the difficulties involved with integrating technical considerations in the creative architectural process. One aspect of the problem is the neglect of technical factors during the initial phase of the design that, as the authors argued, results from changing the work environment and the laborious nature of the design process. Many of the current programs require the user to input a great deal of numerical values that are needed for the energy analysis. Although there are some programs that attempt to assist the user by setting default values, these programs distract the user with their extensive arrays of data. The appropriate design tool is the one that helps the user to easily view the principal components of the building design and specify their behaviors and interactions. Data abstraction and information parsimony are the key concepts in developing a successful design tool. Three different approaches for developing an appropriate CAAD tool were found in the literature. Although there are several similarities among them, each is unique in solving certain aspects of the problem. Brown and Novitski [1987] emphasize the learning factor of the tool as well as its highly graphical user interface. Degelman and Kim [1988] emphasize knowledge acquisition and the provision of simulation modules. The Windows and Daylighting Group of Lawrence Berkeley Laboratory (LBL) emphasizes the dynamic structuring of information, the intelligent linking of data, the integrity of the different issues of design and the design process, and the extensive use of images [Schuman et al 19881, these attributes incidentally define the word hypermedia. The LBL model, which uses hypermedia, seems to be the more promising direction for this type of research. However, there is still a need to establish a new model that integrates all aspects of the problem. The areas in which the present research departs from the LBL model can be listed as follows: it acknowledges the necessity of regarding the user as the center of the CAAD tool design, it develops a model that is based on one of the high level theories of human-computer interaction, and it develops a prototype tool that conforms to the model.

title	Puzzle-Making : What Architects Do When No One is Looking
source	New York: Wiley-Interscience, 1987. pp. 37-52. includes bibliography
summary	The thesis of this paper is that architects work in a manner that is antithetical to problem-solving because they cannot explicate desired effects prior to their realization through the design process. In an attempt to clarify architecture's uncommon mode of action the author suggests that instead of specifying what they are trying to accomplish prior to their attempts to accomplish it as problem-solver do, architects treat design as a search for the most appropriate effects that can be attained in a unique context. They seek sets of combinatorial rules that will result in an internally consistent fit between a kit of parts and the effects that are achieved when those parts are assembled in a certain way

doi	https://doi.org/10.52842/conf.acadia.1987.109
summary	This paper discusses the apparent correlation between faculty computer literacy and the success of integrating computing into architectural education. Relevant questions of a 1985 national survey which was conducted to study the historical development of faculty computer utilization are analyzed and interpreted. The survey results are then used as the basis for a series of recommendations given for increasing computer literacy among faculty in architectural schools, thus increasing the integration of computing.

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	Proceedings of the 1st European Full-Scale Workshop Conference / ISBN 87-88373-20-7 / Copenhagen (Denmark) 15-16 January 1987, pp. 31-35
summary	My point of departure is a long standing interest in close human communication. I have been much interested in the multiplicities of communicative levels between persons sharing daily life, e.g. spouses in a household. In the mid-sixties I was working with the first videotapings of marital dyads in a laboratory setting. The "interplay- analysis" which I developed at that time, however, was hampered by the lack of contextual naturalism in the setting. Since - working in the field of "altered states of consciousness" - I came to question the adequacy of studies of extra-ordinary states, in view of the lacking methodology for dealing even with the ranges of the variable ordinary states of mind over the 24-hour cycle in everyday life, and their potential relation to the micro-structure of the habitual ongoing activities of members of a household.

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.

doi	https://doi.org/10.52842/conf.acadia.1987.029
summary	This paper presents a critical evaluation of two years of experience in using computer aided design as the primary graphic tool in an architectural design studio. In addition to significant benefits being realized, it was found that in a number of circumstances the graphic tool seemed to place unnecessary or inappropriate constraints on the designer. A critical examination of this tendency revealed that there may be a discrepancy between the theoretical framework in which computer aided design systems are developed and used, and the conceptual framework of contemporary architectural thought. These issues arising from the studio experience, are discussed and placed within the context of current theoretical concerns in architecture.
