title Computer aided descriptive geometry
source Vienna University of Technology
summary The main aim of this thesis is the creation of a software package for descriptive geometry. Why there is a need for such a descriptive geometry software? In descriptive geometry the ability of space perception is trained by solving spatial problems graphically with the use of a few constructions: Hence the solution of each problem consists of two parts: 1) 3D-part: After analyzing the spatial problem it is cleared how to proceed step by step in space. 2) 2D-part: Due to the basic rules of descriptive geometry for each step of the solving strategy the corresponding 2D-construction has to be carried out graphically. By use of CAD-DG the 2nd part can be replaced again by a 3D-part: Each step is solved using the basic routines offered in the menu. That means that each step is solved analytically but instead of any output of numbers the solution is immediately displayed in the main views on the screen. Therefore the user neither needs to apply formulas of analytic geometry nor has to take care of any coordinates. He still works directly with geometric objects in a graphic representation

summary It should be expected, in a Congress, that participants bring with them, not only ideas, but also results or, at least, stimulating images. In the Laboratory of Architectural Graphic Techniques at the ETS of Barcelona, we have spent some time generating images directly related with architecture, based on the work of both students and professors. These images have been produced with academic purposes, but also in relation with some works carried out with City Institutions interested in the study of the evaluation of environment visual impact and the role that computers may play in this area. In our previous Congress, in Barcelona, we showed some of these images, obtained by direct digital processing of bitmaps. In another Congress, later, we showed some other images, obtained by rendering, with simple local models (Phong models) and some tricks that helped to make them more realistic. Although I do agree with the old chinese saying that a good image is worth a thousand words, in this case, I have thought more convenient to present a paper that may be read quietly by those interested in these subjects, that might be useful just as it gathers references known by many but grouped in a particular order, and that pretends, respectfully, to criticize the actual situation. This can explain why we consider that the results we have obtained should be improved by new and better techniques and why we think that this dissatisfaction should be shared by others who do not seem to feel the same as we do. The aim of this contribution is, therefore, to reflect on the actual situation and the ways there seem to be open for us to follow.

title Toward a procedure of computer simulation in the restoration of historical architecture
source AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary In the field of architectural design, “visualization¨ generally refers to some media, communicating and representing the idea of designers, such as ordinary drafts, maps, perspectives, photos and physical models, etc. (Rahman, 1992; Susan, 2000). The main reason why we adopt visualization is that it enables us to understand clearly and to control complicated procedures (Gombrich, 1990). Secondly, the way we get design knowledge is more from the published visualized images and less from personal experiences (Evans, 1989). Thus the importance of the representation of visualization is manifested.Due to the developments of computer technology in recent years, various computer aided design system are invented and used in a great amount, such as image processing, computer graphic, computer modeling/rendering, animation, multimedia, virtual reality and collaboration, etc. (Lawson, 1995; Liu, 1996). The conventional media are greatly replaced by computer media, and the visualization is further brought into the computerized stage. The procedure of visual impact analysis and assessment (VIAA), addressed by Rahman (1992), is renewed and amended for the intervention of computer (Liu, 2000). Based on the procedures above, a great amount of applied researches are proceeded. Therefore it is evident that the computer visualization is helpful to the discussion and evaluation during the design process (Hall, 1988, 1990, 1992, 1995, 1996, 1997, 1998; Liu, 1997; Sasada, 1986, 1988, 1990, 1993, 1997, 1998). In addition to the process of architectural design, the computer visualization is also applied to the subject of construction, which is repeatedly amended and corrected by the images of computer simulation (Liu, 2000). Potier (2000) probes into the contextual research and restoration of historical architecture by the technology of computer simulation before the practical restoration is constructed. In this way he established a communicative mode among archeologists, architects via computer media.In the research of restoration and preservation of historical architecture in Taiwan, many scholars have been devoted into the studies of historical contextual criticism (Shi, 1988, 1990, 1991, 1992, 1995; Fu, 1995, 1997; Chiu, 2000). Clues that accompany the historical contextual criticism (such as oral information, writings, photographs, pictures, etc.) help to explore the construction and the procedure of restoration (Hung, 1995), and serve as an aid to the studies of the usage and durability of the materials in the restoration of historical architecture (Dasser, 1990; Wang, 1998). Many clues are lost, because historical architecture is often age-old (Hung, 1995). Under the circumstance, restoration of historical architecture can only be proceeded by restricted pictures, written data and oral information (Shi, 1989). Therefore, computer simulation is employed by scholars to simulate the condition of historical architecture with restricted information after restoration (Potier, 2000). Yet this is only the early stage of computer-aid restoration. The focus of the paper aims at exploring that whether visual simulation of computer can help to investigate the practice of restoration and the estimation and evaluation after restoration.By exploring the restoration of historical architecture (taking the Gigi Train Station destroyed by the earthquake in last September as the operating example), this study aims to establish a complete work on computer visualization, including the concept of restoration, the practice of restoration, and the estimation and evaluation of restoration.This research is to simulate the process of restoration by computer simulation based on visualized media (restricted pictures, restricted written data and restricted oral information) and the specialized experience of historical architects (Potier, 2000). During the process of practicing, communicates with craftsmen repeatedly with some simulated alternatives, and makes the result as the foundation of evaluating and adjusting the simulating process and outcome. In this way we address a suitable and complete process of computer visualization for historical architecture.The significance of this paper is that we are able to control every detail more exactly, and then prevent possible problems during the process of restoration of historical architecture.

doi https://doi.org/10.52842/conf.ecaade.1993.x.u8b
summary During the first year students are taught that it is important to learn to evaluate their projects themselves. Therefore a checklist is introduced and explained over the year which can be used by the students to formulate their criteria, evaluation scales and weighting factors. The main aspects that are evaluated are utility, structural and manufacturing aspects. Only little attention during the first year is given to legal and economical aspects. Main goal is to develop a systematic and integrated approach towards the evaluation of design projects. The evaluation of the student is compared with the judgement of the teacher. Final marks are given by the teacher.

title Describing Spaces of Rectangular Dissections via Grammatical Programming
source CAAD Futures ‘93 [Conference Proceedings / ISBN 0-444-89922-7] (Pittsburgh / USA), 1993, pp. 143-158
summary For the description of design spaces, grammatical programs offer several advantages over conventional grammars: (1) they integrate rewrite rules with more general non-deterministic functions, (2) they permit a range of programming styles from purely declarative to purely procedural, (3) they can describe spaces Of constrained, parametric designs, and (4) they permit design space descriptions to be developed modularly. We demonstrate these features of grammatical programming by way of a simple example that generates spaces of rectangular dissections.

title Exploring Structural Morphology Using CAD
source [eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
doi https://doi.org/10.52842/conf.ecaade.1993.x.d1k
summary Often in the design process the student's imagination is restricted by their inability to visualise, model or accurately sketch ideas for innovative structural systems. By using CAD as a design tool it is possible to explore the morphology of complex structures and to be able to produce perspective drawings of them with relative ease. Within AutoCAD there is a small library of standard three-dimensional objects and surfaces that can be called upon to generate more complex forms. However, to further facilitate the architectural design process, an extended library of innovative structural forms would allow the professional designer, or student, greater design freedom and any increase in the palette of structural forms available should stimulate creativity. As practical examples, the paper describes how students have been encouraged to experiment with the use of structures which can only be physically modelled with difficulty and which are also difficult to represent on the two- dimensional surface of the drawing board unless the geometry has previously been determined by the methods described. These are (i) Reciprocal Frame three-dimensional beam grillage structures and (ii) plate domes created from lattice structures by point-to- plane duality. The problem, of representation of these structures has been overcome, in the first case, by generating AutoLISP procedures to draw the complex three-dimensional geometrical form automatically in AutoCAD and, in the second case, by the development of the computer program CADual.

title Common Illumination between Real and Computer Generated Scenes
source Proceedings Graphics Interface '93, pp. 254-262, 1993
summary The ability to merge a real video image (RVI) with a computer- generated image (CGI) enhances the usefulness of both. To go beyond "cut and paste" and chroma-keying, and merge the two images successfully, one must solve the problems of common viewing parameters, common visibility and common illumination. The result can be dubbed Computer Augmented Reality (CAR). We present in this paper techniques for approximating the common global illumination for RVIs and CGIs, assuming some elements of the scene geometry of the real world and common viewing parameters are known. Since the real image is a projection of the exact solution for the global illumination in the real world (done by nature), we approximate the global illumination of the merged image by making the RVI part of the solution to the common global illumination computation. The objects in the real scene are replaced by few boxes covering them; the image intensity of the RVI is used as the initial surface radiosity of the visible part of the boxes; the surface reflectance of the boxes is approximated by subtracting an estimate of the illuminant intensity based on the concept of ambient light; finally global illumination using a classic radiosity computation is used to render the surface of the CGIs with respect to their new environment and for calculating the amount of image intensity correction needed for surfaces of the real image. An example animation testing these techniques has been produced. Most of the geometric problems have been solved in a relatively ad hoc manner. The viewing parameters were extracted by interactive matching of the synthetic scene with the RVIs. The visibility is determined by the relative position of the "blocks" representing the real objects and the computer generated objects, and a moving computer generated light has been inserted. The results of the merging are encouraging, and would be effective for many applications.

title Looking into Endoscopy - The Limitations of Evaluation in Architectural Design

summary The means available to architects in their age-old task of creating (most usually, though not necessarily) buildings that do not yet exist (ie. virtual realities), can be seen as falling into two groups. Those that help us develop architectural ideas (exploring), and those that help us evaluate or test them (illustrating). In the former category, we have, for instance, the ”drawing on the back of the envelope”, the discursive brainstorm, and the design ”conversation with ourselves via paper and pencil” (the drawing strikes back). In the latter, we may include physical model building, careful (projective) drawing (including drawings that are instructions for making), mathematical and design science modelling and calculating, visualising techniques such as the rendered perspective, most CAD (computer aided design) work and architectural endoscopy. These techniques may be thought of in two ways, as Bosselman reported: the explanation (eg. the organisational plan) and the experience (eg the ”photo-realistic” perspective). Attached to these we have rules for success, such as those of ”style” (in the broad sense of the personal style that allows us to assume that we have answers to problems that have yet to appear). It should be clear even from the list above that there are many more techniques and technologies for evaluation (illustration) than for exploration (design): such is the mystery of design. It is the primary purpose of this paper to invite those involved in providing the enormous effort that has gone into making such techniques for illustration — evaluation — to consider how their efforts help with that other, and crucial, area — that of exploring: and to redress some of the balance of that effort towards exploration. For it occurs to me (as a teacher of architecture), that evaluation does not provide a course for action — it merely helps us determine what may be wrong (according to some criteria with which we choose not to argue). And, no matter how right or wrong a design may be, knowing that it is wrong doesn’t help us either modify it, or find a better initial idea. It only tells us we are not right — always assuming the evaluative model is correct; perhaps.

title On the Correlation of Design and Computational Techniques in Architectural Education

summary Many studies employ analyses of human intelligence as justification or guideline for the development of machine intelligence. The main benefit brought on by such studies has been the improvement of our understanding of both human and machine intelligence. In teaching architecture with computers the same approach can make explicit design techniques architects use by means of equivalent or similar computational techniques. Explicitation of design techniques leads to a better understanding of architects' activities, as well as to which computer tools can offer automated support to these activities. In the curriculum of the Faculty of Architecture, Delft University of Technology, relations and correspondences between computational and design techniques form a major underlying theme in computer-aided design courses. The purposes of this theme are (i) comprehension of the computational structure of a computer design tool, and (ii) explanation of how such computational structures relate to architectural design. (correspondences between the computational principles of computer programs and design techniques are instrumental in defining the scope of each computer tool in architectural design while improving the students' understanding of architectural design as a cognitive process and thus promoting automation as a natural extension of established conventional practices. The paper outlines the correlation of computational and design techniques in the case of electronic spreadsheets. Spreadsheets are introduced through a thorough presentation of the various kinds and aspects of constraint propagation, their underlying computational principle. Numerical constraint propagation is explained by means of spreadsheet applications for simple numerical calculations. Symbolic constraint propagation is presented in the framework of machine perception. Both forms are then linked to architectural design through parametric design and the recognition of spaces in floor plans. Exercises linked to spreadsheets and constraint propagation include the parametric calculation of stairs and making parametric variations of a building on the basis of floor area calculations.

title The Vector-drawing as a Means to Unravel Architectural Communication in the Past
source [eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
doi https://doi.org/10.52842/conf.ecaade.1993.x.q9a
summary Unlike in painting, in architecture one single person never controls the whole process between conception and realization of a building. Ideas of what the building will eventually look like, have to be conveyed from patron to the actual builders, by way of drawings. Generally the architect is the key-figure in this process of communication of visual ideas. Nowadays many architects design their new buildings by using computers and Computer-Aided (Architectural) Design programs like AutoCad and VersaCAD. Just like traditional drawings, all these computer drawings are in fact vector-drawings; a collection of geometrical primitives like lines, circle segments etc. identified by the coordinates of their end points. Vector-based computer programs can not only be used to design the future, but also as a means to unravel the architectural communication in the past. However, using the computer as an analyzing tool for a better comprehension of the past is not as simple as it seems. Historical data from the past are governed by unique features of date and place. The complexity of the past combined with the straightforwardness of the computer requires a pragmatic and basic approach in which the computer acts as a catalytic agent, enabling the scholar to arrive manually at his own - computer-assisted - conclusions. From this it turns out that only a limited number of projects of a morphological kind are suited to contribute to new knowledge, acquired by the close-reading of the information gained by way of meaningful abstraction. An important problem in this respect is how to obtain the right kind of architectural information. All four major elements of the building process - architect, design, drawing and realization - have their own different and gradually shifting interpretations in the past. This goes especially for the run-of-the-mill architecture which makes up the larger part of the historical urban environment. Starting with the architect, one has to realize that only a very limited part of mainstream architecture was designed by architects. In almost all other cases the role of the patron and the actual builder exceeds that of the architect, even to the extent that they designed buildings themselves. The position of design and drawing as means of communication also changed in the past. Until the middle of the nineteenth century drawings were not the chief means of communication between architects and builders, who got the gist of the design from a model, or, encountering problems, simply asked the architect or supervisor. From the nineteenth century onwards the use of drawings became more common, but almost never represented the building entirely "as built". In 1991 I published my Ph.D. thesis: Constructing the past: computerassisted architectural-historical research: the application of image-processing using the computer and Computer-Aided Design for the study of the urban environment, illustrated by the use of treatises in seventeenth-century architecture (Utrecht 1991). Here, a reconstruction of this historical communication process will be presented on the basis of a project studying the use of the Classical orders as prescribed in various architectural treatises, compared to the use of the orders in a specific group of still existing buildings in The Netherlands dating from the late sixteenth and entire seventeenth century. Comparisons were made by using vector-drawings. Both the illustrations in the the treatises and actual buildings were "translated" into computer-drawings and then analyzed.

title Cityspace, Cyberspace, and The Spatiology of Information
source Boyer,C. & Gandelsonas.,M. The New Urbanism Princeton University Press
summary The concept of space has been critical to architectural theory for over seventy years now. It remains however, an elusive idea, on the one hand meaning and referring to everything, on the other hand meaning and referring to nothing. Why? Is it because "space," like "time," is a category outside of which thinking itself seems to be impossible, just as Kant asserted? Is it simply one of those irreducible, universal without which the world as such would cease to in any sense, let alone be of, or perceived by, sentient beings givens be thought Certainly to suggest that space itself is an active, causative agent of some sort risks opening that discussion up to universalizing of the most extreme and vacuous kind. For if I am not to be a dualist, positing a separate, a-spatial and a-temporal realm for thought and feeling, then what in the real world, I can easily ask, occupies neither space nor time? What is it that cannot be reduced, be analyzed, or be spoken of finally in the language of position, duration, connection, inclusion, transformation, and so forth? Nothing. If we wish to reach deeply into the "nature" of "space itself" then, I believe we must allow into it, as it were, of some sort: not the aether of Nineteenth century science perhaps, but a registering, tracing, questioning, remembering substance, spread as thinly as we can imagine but present nonetheless, and definitive of versus because of how it pools, how it vibrates, how it scatters difference, a substance here there difference.

title A Computer-Assisted Diagramming System
source Swiss Federal Institute of Technology, ETH Zurich
summary This research investigates characteristics and generation of graphic diagrams used in support of analysis, presentation and synthesis of information in various domains. The research is aimed at the development of a software system which can be used to specify, generate and manipulate diagrams similar to the way they are represented and operated upon in traditional media.Diagrams are graphic representations of symbolic propositions that allow tentative reasoning and inferencing, and enable a person to focus on selected aspects of a situation that are deemed of interest. The economy and directness of expression found in diagrams seem to be the prime reasons why they are so ubiquitous in many domains. Despite these advantages, studies into supporting diagrammatic representations using computers are rather sparse. This research is an attempt at developing a comprehensive framework of thought in this direction.In the context of design disciplines like architecture, this research forms a part of the continuum of studies in computer aided design techniques and tools. While a large number of tools and techniques in CAD have emerged so far, usage of such tools, due to their underlying representations, expects and demands commitment of too many details too early in the design process. This research is aimed at characterizing and developing a computer based diagramming system to support tentative reasoning using diagrams, and thus hopes to extend the scope of CAD environments in design. The thesis first articulates motivations for this topic in detail. Next, a discussion on the role played by diagrams as conceptual tools in various domains is presented. It is followed by a detailed look at characteristics and components of diagrams viewed as a graphic communication system. Next, a comprehensive set of requirements for an ideal software environment for diagramming tasks is developed. A prototype system called CDT was implemented and is used to demonstrate ideas developed in this research. The study concludes with some observations on contributions of this research effort and possible future extensions.

title Implicit Learning and Tacit Knowledge: An Essay on the Cognitive Unconscious
source New York: Oxford University Press
summary In this new volume in the Oxford Psychology Series, the author presents a highly readable account of the cognitive unconscious, focusing in particular on the problem of implicit learning. Implicit learning is defined as the acquisition of knowledge that takes place independently of the conscious attempts to learn and largely in the absence of explicit knowledge about what was acquired. One of the core assumptions of this argument is that implicit learning is a fundamental, "root" process, one that lies at the very heart of the adaptive behavioral repertoire of every complex organism. The author's goals are to outline the essential features of implicit learning that have emerged from the many studies that have been carried out in a variety of experimental laboratories over the past several decades; to present the various alternative perspectives on this issue that have been proposed by other researchers and to try to accommodate these views with his own; to structure the literature so that it can be seen in the context of standard heuristics of evolutionary biology; to present the material within a functionalist approach and to try to show why the experimental data should be seen as entailing particular epistemological perspectives; and to present implicit processing as encompassing a general and ubiquitous set of operations that have wide currency and several possible applications. Chapter 1 begins with the core problem under consideration in this book, a characterization of "implicit learning" as it has come to be used in the literature. Reber puts this seemingly specialized topic into a general framework and suggests a theoretical model based on standard heuristics of evolutionary biology. In his account, Reber weaves a capsule history of interest in and work on the cognitive unconscious. Chapter 2 turns to a detailed overview of the experimental work on the acquisition of implicit knowledge, which currently is of great interest. Chapter 3 develops the evolutionary model within which one can see learning and cognition as richly intertwining issues and not as two distinct fields with one dominating the other. Finally, Chapter 4 explores a variety of entailments and speculations concerning implicit cognitive processes and their general role in the larger scope of human performance

summary Jaron Lanier is a major spokesperson of our society's hottest new technology: VR or virtual reality. He expressed his faith in the VR movement in this quote which appears in The User's Guide to the New Edge published by Mondo 2000. In its most technical sense, VR has attracted the attention of politicians in Washington who wonder if yet another technology developed in the United States will find its application across the globe in Asia. In its most human element, an entire "cyberpunk movement" has appealed to young minds everywhere as a seemingly safe form of hallucination. As architecture students, educators, and practitioners around the world are becoming attracted to the possibilities of VR technology as an extension of 3D modeling, visualization, and animation, it is appropriate to consider an overview of virtual reality.

In virtual reality a user encounters a computersimulated environment through the use of a physical interface. The user can interact with the environment to the point of becoming a part of the experience, and the experience becomes reality. Natural and

instinctive body movements are translated by the interface into computer commands. The quest for perfection in this human-computer relationship seems to be the essence of virtual reality technology.

To begin to capture the essence of virtual reality without first-hand experience, it is helpful to understand two important terms: presence and immersion. The sense of presence can be defined as the degree to which the user feels a part of the actual environment. The more reality the experience provides, the more presence it has. Immersion can be defined as the degree of other simulation a virtual reality interface provides for the viewer. A highly immersive system might provide more than just visual stimuli; for example, it may additionally provide simulated sound and motion, and simultaneously prevent distractions from being present.

title The Evolution of an Interface for Choreographers Evolving Design
source Proceedings of ACM INTERCHI'93 Conference on Human Factors in Computing Systems 1993 pp. 115-122
summary This paper describes the evolution of the interface to Life Forms, a compositional tool for the creation of dance choreography, and highlights some of the important lessons we have learned during a six year design and implementation period. The lessons learned can be grouped into two categories: 1) Process, and 2) Architecture of the Interface. Our goal in developing a tool for choreography has been to provide computer-based creative design support for the conception and development of dance. The evolution was driven by feedback from the choreographers and users who were members of the development team, combined with our knowledge of current thinking on design and composition. Although the interface evolved in a relatively unconstrained way, the resulting system has many of the features that theoretical discussion in human interface design has projected as necessary. The Life Forms interface has evolved incrementally with one major discontinuity where adoption of a new compositional primitive required a completely new version. The choreography and composition of a dance is a complex synthesis task which has much in common with design. Thus, the lessons learned here are applicable to the development of interfaces to such applications as computer aided design.

summary This paper gives an overview of a research program initiated in the Architectural Design Department of the Escola Tècnica Superior d'Arquitectura de Barcelona on issues of communication and collaboration in computer aided design. The work is centered around emerging design situations which can be attributed directly to the incorporation of new technologies in education and practice. One of these is the "design triangle" composed of a traditional designer, a CAD workstation and a computer literate collaborator acting as the design medium. Another is the "virtual workshop" consisting of design collaboration involving large-scale distributed communications networks. The research program stresses three common characteristics of these situations which it aims to study in parallel in the setting of an design workshop. The first of these is the characteristic of distance, both physical and conceptual, which separates, on the one hand, the traditional designer from the CAD document and, on the other, the participants of a distributed workshop from each other and each others' thinking. The second, is the typically hybrid nature of such situations where computer technology interacts with more traditional techniques and alternative media are combined both at the level of production and in channels and modes of communication. And finally, the third and most significant for the methodology of the research program, is the fact that both the design triangle and the virtual workshop make explicit aspects of design activity, interaction and intentions which remain hidden or are only implicit in traditional designing.

Castleman concentrates on those techniques that have proven most useful in practice. Part I presents several important concepts that can be developed without detailed mathematical analysis for a basic understanding. Part II addresses techniques that rely more on mathematics and eaborates analytically on certain concepts introduced in Part I. Part III covers specific application aread that are particularly in industry, science, and medicine. Contents: Preface; Images and Digital Processing; Digitizing Images; Digital Image Display; Image Processing Software; The Gray Level Histogram; Point Operations; Algebraic Operations; Geometric Operations; Filter Design; Wavelet Transformations; Image Restorations; Image Compression; Three Dimensional Image Processing; Appendices; Index.

summary The boundaries of augmented reality in the academic field are now being explored at an ever increasing level. In this paper we present the initial findings of an educational project focusing on the use of augmented reality in the design process of an architectural student. The study seeks to evaluate the use of AR as a tool in the design stages, allowing effective exploration of spatial qualities of design projects undertaken in the studio. The learning process is guided by the exploration and detection of a design idea in both form and function, with the virtual environment providing a dynamic environment (Mantovani, 2001). This is further reflected in the constructivist theory where the learning processes use conceptual models, which are used to create incremental stages that become the platform to attain the next [Winn, 1993]. The additional benefit of augmented reality within the learning journey is the ability of the students to visually explore the architectural forms they are creating in greater depth.

title The Relation Between the Internet Infrastructure and the Internet Industry
source CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary The scene is set by a survey of new location factors for mobile investment in Europe, published by the European Commission in 1993. This leads to two questions the first of which concerns the exact definition of the Internet industry in order to avoid confusion. The definitional issue appears to be far from simple. The second question is about the Internet infrastructure. This infrastructure, although new and almost invisible, can nevertheless be mapped and measured with less ambiguity than the Internet industry. How to connect the two? How to establish the importance of the Internet infrastructure for the location of the Internet industry? Technological determinism and urban dissolution are debunked as myths. A conceptual innovation is called for: to conceive of the connection between infrastructure and industry as a match between networks. By way of conclusion, this match is discussed from the viewpoint of non-hub cities or regions.

summary This paper shows work exemplifying the further extent of computer capabilities in the field of design. The work stems from a belief that for computers to be used effectively within the architectural profession their utility must stretch far beyond the process of description of geometric data, but be incorporated in the fundamental roots of design: that of conceptual design. Computers can be used to access the knowledge we have and then formulate this knowledge into a working language of design. Computers can be used to generate space and form in accordance with any relationship the designer may choose to set. This allows them to be used from the very conception of design. It is only by working from the very beginning, the very basis of the design of a building that we can fully develop the integration of computers in the construction industry. The work undertaken sets out primarily to explore one of the ways computers could be used in the field of architectural design. In recognition that an important byproduct of any design search is the enhanced understanding of the problem itself, the work was directed towards a particular project. This allowed each stage of thought to be to be considered as it arose and subsequently incorporated into the design model. The work does not attempt to automise the design process but simply tries to explore some of the opportunities offered by computers and see if they can be easily incorporated into the design process offering design solutions that may not otherwise have been considered. The exploration resulted in a simple design process model that incorporates the more accessible and useful aspects of computer technology.
