title Efficient Alias-Free Rendering using Bit-masks and Look-up Tables
source SIGGRAPH '85 Conference Proceedings. July, 1985. vol. 19 ; no. 3: pp. 53-59 : ill. (some col.). includes bibliography
summary The authors demonstrate methods of rendering alias-free synthetic images using a precomputed convolution integral. The method is based on the observation that a visible polygon fragment's contribution to an image is solely a function of its position and shape, and that within a reasonable level of accuracy, a limited number of shapes represent the majority of cases encountered in images commonly rendered. The basic technique has been applied to several different rendering algorithms. A version of the newly non-uniform sampling technique implemented in the same program but with different tables values was introduced

title Modeling Concepts for VLSI CAD Objects
source ACM Transactions on Database Systems 10 No. 3 - pp. 322-346
summary VLSI CAD applications deal with design objects that have an interface description and an implementation description. Versions of design objects have a common interface but differ in their implementations. A molecular object is a modeling construct which enables a database entity to be represented by two sets of heterogeneous records, one set describes the object's interface and the other describes its implementation. Thus a reasonable starting point for modeling design objects is to begin with the concept of molecular objects. In this paper, we identify modeling concepts that are fundamental to capturing the semantics of VLSI CAD design objects and versions in terms of molecular objects. A provisional set of user operations on design objects, consistent with these modeling concepts, is also defined. The modeling framework that we present has been found useful for investigating physical storage techniques and change notification problems in version control. REFERENCES

title A Taxonomy of Architecture: Core of a Theory of Design
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary The authors developed a taxonomy of concepts in architectural design. It was accepted by the Advisory Committee for education in the field of architecture, a committee advising the European Commission and Member States, as a reference for their task to harmonize architectural education in Europe. The taxonomy is based on Domain theory, a theory developed by the authors, based on General Systems Theory and the notion of structure according to French Structuralism, takes a participatory viewpoint for the integration of knowledge and interests by parties in the architectural design process. The paper discusses recent developments of the taxonomy, firstly as a result of a confrontation with similar endeavours to structure the field of architectural design, secondly as a result of applications of education and architectural design practice, and thirdly as a result of theapplication of some views derived from the philosophical work from Charles Benjamin Peirce. Developments concern the structural form of the taxonomy comprising basic concepts and levelbound scale concepts, and the specification of the content of the fields which these concepts represent. The confrontation with similar endeavours concerns mainly the work of an ARCUK workingparty, chaired by Tom Marcus, based on the European Directive from 1985. The application concerns experiences with a taxonomy-based enquiry in order to represent the profile of educational programmes of schools and faculties of architecture in Europe in qualitative and quantitative terms. This enquiry was carried out in order to achieve a basis for comparison and judgement, and a basis for future guidelines including quantitative aspects. Views of Peirce, more specifically his views on triarchy as a way of ordering and structuring processes of thinking,provide keys for a re-definition of concepts as building stones of the taxonomy in terms of the form-function-process-triad, which strengthens the coherence of the taxonomy, allowing for a more regular representation in the form of a hierarchical ordered matrix.

title Strategic Urban Planning in the Netherlands
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary Since the mid-1980s, several Dutch towns have initiated many urban planning and design activities for their existing area. This represented a shift in that previous urban planning projects typicallyconcerned expansion in the outskirts of the city, or urban renewal. The complex and expensive renovation of the existing housing stock rarely allowed a deep interest in urban design. Since 1985, attention shifted from the housing stock to the city as a whole. Furthermore, public andprivate actors increasingly become involved in the planning process. It became clear that a more comprehensive plan for the whole existing town or region was needed. Conventional planning instruments were considered ill-suited for this new challenge. The paper discusses promising attempts of various urban planning instruments to get a stronger but also more flexible hold on thetransformation of the urban planning area in the Netherlands. These new planning instruments have three common characteristics: (i) they give special attention to the different levels of urban management needed for different urban areas, (ii) these strategic plans provide an integral view on the urban developments, and (iii) these plans introduce a new strategy to deal with both private initiatives to transform urban sites and monitor wishes, proposals, etc. from inhabitants in the neighbourhoods. A comparative analyses of several cities indicates, however, that, in addition to these common characteristics, major differences between their strategic plans exist depending upon their historic patrimonium, economic status and planning tradition.

title Any Progress in Systematic Design?
source Computer-Aided Architectural Design Futures [CAAD Futures Conference Proceedings / ISBN 0-408-05300-3] Delft (The Netherlands), 18-19 September 1985, pp. 5-15
summary In order to discuss this question it is necessary to reflect awhile on design methods in general. The usual categorization discusses 'generations' of design methods, but Levy (1981) proposes an alternative approach. He identifies five paradigm shifts during the course of the twentieth century which have influenced design methods debate. The first paradigm shift was achieved by 1920, when concern with industrial arts could be seen to have replaced concern with craftsmanship. The second shift, occurring in the early 1930s, resulted in the conception of a design profession. The third happened in the 1950s, when the design methods debate emerged; the fourth took place around 1970 and saw the establishment of 'design research'. Now, in the 1980s, we are going through the fifth paradigm shift, associated with the adoption of a holistic approach to design theory and with the emergence of the concept of design ideology. A major point in Levy's paper was the observation that most of these paradigm shifts were associated with radical social reforms or political upheavals. For instance, we may associate concern about public participation with the 1970s shift and the possible use (or misuse) of knowledge, information and power with the 1980s shift. What has emerged, however, from the work of colleagues engaged since the 1970s in attempting to underpin the practice of design with a coherent body of design theory is increasing evidence of the fundamental nature of a person's engagement with the design activity. This includes evidence of the existence of two distinctive modes of thought, one of which can be described as cognitive modelling and the other which can be described as rational thinking. Cognitive modelling is imagining, seeing in the mind's eye. Rational thinking is linguistic thinking, engaging in a form of internal debate. Cognitive modelling is externalized through action, and through the construction of external representations, especially drawings. Rational thinking is externalized through verbal language and, more formally, through mathematical and scientific notations. Cognitive modelling is analogic, presentational, holistic, integrative and based upon pattern recognition and pattern manipulation. Rational thinking is digital, sequential, analytical, explicatory and based upon categorization and logical inference. There is some relationship between the evidence for two distinctive modes of thought and the evidence of specialization in cerebral hemispheres (Cross, 1984). Design methods have tended to focus upon the rational aspects of design and have, therefore, neglected the cognitive aspects. By recognizing that there are peculiar 'designerly' ways of thinking combining both types of thought process used to perceive, construct and comprehend design representations mentally and then transform them into an external manifestation current work in design theory is promising at last to have some relevance to design practice.

title Computational Experiments with a Feature Based Stereo Algorithm
source IEEE Trans. Pattern Anal. Machine Intell., Vol. PAMI-7, No. 1
summary Computational models of the human stereo system' can provide insight into general information processing constraints that apply to any stereo system, either artificial or biological. In 1977, Marr and Poggio proposed one such computational model, that was characterized as matching certain feature points in difference-of-Gaussian filtered images, and using the information obtained by matching coarser resolution representations to restrict the search'space for matching finer resolution representations. An implementation of the algorithm and'its testing on a range of images was reported in 1980. Since then a number of psychophysical experiments have suggested possible refinements to the model and modifications to the algorithm. As well, recent computational experiments applying the algorithm to a variety of natural images, especially aerial photographs, have led to a number of modifications. In this article, we present a version of the Marr-Poggio-Gfimson algorithm that embodies these modifications and illustrate its performance on a series of natural images.

title Knowledge-Based Computer-Aided Design to Assist Designers of Physical Artifacts
source 1985. [15] p. : ill. includes bibliography
summary The objectives of this project are to increase the productivity of physical designers, and to improve the quality of designed artifacts and environments. The means for achieving these objectives include the development, implementation and verification of a broad-based methodology to be used for building context-sensitive computer-aided design systems to facilitate the design and fabrication of physical artifacts. Such systems will extend computer aides for design over the earliest phases of the design process and thus facilitate design-capture in addition to the common design-communication utilities they currently provide. They will thus constitute intelligent design assistants that will relieve the designer from the necessity to deal with some design details, as well as the need to explicitly manage the consistency of the design database. The project employs principles developed by Artificial Intelligence methods that are used in non-deterministic problem solving processes that represent data and knowledge in distributed networks. Principles such as object-centered data factorization and message-based change propagation techniques are implemented in an existing architectural computer-aided design system and field-tested in a practicing Architectural/Engineering office

title A Computational Tool for Evaluation of Seismic Performance of RC Buildings
source February, 1990. [1] 15 p. : ill. graphs, tables. includes bibliography: p. 10-11
summary Recent events have demonstrated the damaging power of earthquakes on structural assemblages resulting in immense loss of life and property (Mexico City, 1985; Armenia, 1988; San Francisco, 1989). While the present state-of-the-art in inelastic seismic response analysis of structures is capable of estimating response quantities in terms of deformations, stresses, etc., it has not established a physical qualification of these end-results into measures of damage sustained by the structure wherein system vulnerability is ascertained in terms of serviceability, repairability, and/or collapse. An enhanced computational tool is presented in this paper for evaluation of reinforced concrete structures (such as buildings and bridges) subjected to seismic loading. The program performs a series of tasks to enable a complete evaluation of the structural system: (a) elastic collapse- mode analysis to determine the base shear capacity of the system; (b) step-by-step time history analysis using a macromodel approach in which the inelastic behavior of RC structural components is incorporated; (c) reduction of the response quantities to damage indices so that a physical interpretation of the response is possible. The program is built around two graphical interfaces: one for preprocessing of structural and loading data; and the other for visualization of structural damage following the seismic analysis. This program can serve as an invaluable tool in estimating the seismic performance of existing RC buildings and for designing new structures within acceptable levels of damage

title Generative Engineering Databases - Toward Expert Systems
source Computers and Structures. Pergamon Press, 1985. vol. 22: pp. 11-15
summary CADLINE has abstract only. Engineering data management, incorporating concepts of optimization with data representation, is receiving increasing attention. Research in this area promises advantages for many engineering applications, particularly those which use data innovatively. This paper presents a framework for a comprehensive, relational database management system that combines a knowledge base (KB) of design constraints with a database (DB) of engineering data items to achieve a 'generative database' - one which automatically generates new engineering design data according to the design constraints stored in the knowledge base. Thus, in addition to the designer and engineering design and analysis application programs, the database itself contributes to the design process. The KB/DB framework proposed here requires a database that is able to store all of the data normally associated with engineering design and to accurately represent the interactions between constraints and the stored data while guaranteeing its integrity. The framework also requires a knowledge base that is able to store all the constraints imposed upon the engineering design process. The goal sought is a central integrated repository of data, supporting interfaces to a wide variety of application programs and supporting processing capabilities for maintaining integrity while generating new data. The resulting system permits the unaided generation of constrained data values, thereby serving as an active design assistant. This paper suggests this new conceptual framework as a means of improving engineering data representation, generation, use, and management

summary Pergamon Press, 1985. --- Also Published in : Proceedings of the Symposium on Advances and Trends in Structures and Dynamics, Pergamon Press, George Washington University and the National Aeronautics and Space Administration, Washington, D.C. pp. 11-15, Oct.1984. The rapid advances occurring in interactive micro-computing and computer science have provided the engineer with a powerful means of processing, storing, retrieving, and displaying data. The effective use of computer technology in engineering processes and applications is recognized by many as the key to increased individual, company, and national productivity. The implications of this observation for the academic community are clear: we must prepare our students to use computer methods and applications as part of their fundamental education. The proper tradeoff between engineering fundamentals and computer science principles and practices is changing with many of the concepts of engineering now being packaged in algorithms or on computer chips. The components of an education should include operating system fundamentals, data structures, program control and organization, algorithms, and computer architectures. It is critically important for engineering students to receive an education that teaches them these fundamentals. This paper suggests that to convey the essentials of computer science to future engineers requires, in part, the addition of computer courses to the engineering curriculum. It also requires a strengthening of the computing content of many other courses so that students come to treat the computer as a fundamental component of their work. This is a major undertaking, but new engineers graduating with advanced computing knowledge will provide potentially significant future innovations in the engineering profession

summary The establishment of Datacentret (the Data Centre) in summer 1985 was preceded by 15 years slow- moving, arduous work from the early experiments in what was then the computing laboratory under the supervision of architect Per Jacobi, author of the Danish 3D drawing system MONSTER, until 1984, when a special committee was commissioned to draw up proposals for the introduction of teaching in computing at the Architects School. In spring 1985 the school administrators decided that a central computer workshop should be set up and in cooperation with the school's institutes placed jointly in charge of instructing teachers and students, carrying out research and development within the field of architecture and taking steps to work out a curriculum of supplementary training for practising architects. With the aid of a special grant, 12 PC's were successfully acquired in the 2 years that followed, as well as a screen projector and other peripherals.

summary It is commonly recognized that the time-honoured procedure for preparing an architectural design for building on site is inefficient. Each member of a team of consultant professionals makes an independently documented contribution. For a typical project involving an architect and structural, electrical, mechanical and public services engineers there will be at least five separate sets of general- arrangement drawings, each forming a model of the building, primarily illustrating one discipline but often having to include elements of others in order to make the drawing readable. For example, an air-conditioning duct-work layout is more easily understood when superimposed on the room layout it serves which the engineer is not responsible for but has to understand. Both during their parallel evolution and later, when changes have to be made during the detailed design and production drawing stages, it is difficult and time consuming to keep all versions coordinated. Complete coordination is rarely achieved in time, and conflicts between one discipline and another have to be rectified when encountered on site with resulting contractual implications. Add the interior designer, the landscape architect and other specialized consultants at one end of the list and contractors' shop drawings relating to the work of all the consultants at the other, and the number of different versions of the same thing grows, escalating the concomitant task of coordination. The potential for disputes over what is the current status of the design is enormous, first, amongst the consultants and second, between the consultants and the contractor. When amendments are made by one party, delay and confusion tend to follow during the period it takes the other parties to update their versions to include them. The idea of solving this problem by using a common computer-based model which all members of the project team can directly contribute to is surely a universally assumed goal amongst all those involved in computer-aided building production. The architect produces a root drawing or model, the 'Architect's base plan', to which the other consultants have read-only access and on top of which they can add their own write-protected files. Every time they access the model to write in the outcome of their work on the project they see the current version of the 'Architect's base plan' and can thus respond immediately to recent changes and avoid wasting time on redundant work. The architect meanwhile adds uniquely architectural material in his own overlaid files and maintains the root model as everybody's work requires. The traditional working pattern is maintained while all the participants have the ability to see their colleagues, work but only make changes to those parts for which they are responsible.

summary This paper presents an innovative approach on designing large-scale spatial structure with automated robotic 3D-printing. The incipient design approach mainly focused on optimizing structural efficiency at an early design stage by transform the object into a discrete system, and the elements in this system contains unique structural parameters that corresponding to its topology results of stiffness distribution. Back in 2017, the design team already implemented this concept into an experimental project of Cloud Pavilion in Shanghai, China, and the 3D-printed spatial structure was partitioned into five zones represent different level of structure stiffness and filled with five kinds of unit toolpath accordingly. Through further research, an upgrade version, the project of Cloud Pavilion 2.0 is underway and will be completed in January 2019. A detailed description on innovative printing toolpath design in this project is conducted in this paper and explains how the toolpath shape effects its overall structural stiffness. This paper contributes knowledge on integrated design in the field of robotic 3D-printing and provides an alternative approach on robotic toolpath design combines with the optimized topological results.

summary Computational design, especially parametric associative modelling tools, have opened a whole new world of possibility in design exploration. However, their now established use poses further questions regarding how they effect design process and ultimately the quality of the outcomes. Answering those questions requires a better understanding of parametric design process through empirical data. In this paper, we extend a method to systematically capture the design process into a structured data of designer's activity and design states. Analysis of design sessions reveal a unique pattern of parametric modelling and exploration strategies produced by each designer. Capability to save design process into structured design states shows potential to improve process.

title Matchmaker: An Instrument for Matching Demand for and Supply of Buildings and Revealing Specific Discrepancies
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary To match supply and demand of buildings, various approaches are possible. While artificial intelligenceis favoured by some, we think that a less 'heavy' approach can be more cost and time efficient. The casewe have chosen to exemplify our approach concerns architectural heritage. To match supply and demandwhile at the same time respecting the constraints imposed by cultural heritage, it is necessary to bringthem together and to effectuate feasibility studies in the shortest possible time. The feasibility study shouldbe served by tools allowing the various partners to communicate on the level of the match between them, translated in terms of spatial organisation and building constraints. In the past years, our designmorphology group has developed and tested a graphic-based reordering tool which has been applied to large governmental buildings, both existing and new. The same tool can be used for weighted objectives ranking and evaluation, to have a synthetic view of the combined basic preferences and differences of the involved parties as for example in a jury wise evaluation and ranking of alternative proposals. The proposed tool is the electronic and graphic version of the data and association matrices, which have been for a long time recommended for use in the preliminary phases of design. But as long as these instruments could only be drawn and redrawn on paper they were much too ineffectual and found little real application. The developed tool is connected by sub-routines to a computer aided design package, within which the spatial patterns are translated into plans and attached data bases. The matching takes place in a number of steps. The first is to describe the organisation (the demanding party) as functional units which can be made corresponding with spatial units. The prescription of spatial needs can take place in both quantitative and qualitative manners. The Matchmaker tools offer the possibility of interactive clustering of spatial needs. Another step, which can be taken concurrently, is to describe the monument in spatial units and distance relationships. The input can be generated directly within the matrix, but it is much easier, more self evident and realistic to generate this automatically from the draughted plan. The following step is the input of constraints originating from heritage preservation objectives, expressed in levels of authorised intervention. Again, the Matchmaker tools offer here the possibility of visual clustering of spatial units, their relationships and associated properties. In the next step, the matching takes place. In this step the actual positions, properties and constraints of existing spaces in the monument are compared (and visualised by discrepancies views) to the optimised and clustered spatial needs of the end user. In the following phase, the feasibility in terms of space, building fabric and costs can be appraised. Once a compromise has been attained, preliminary proposals can be designed and laid down in terms of drawings. The spatialdesigns can then again be translated into matrix views and evaluated.

title A Strategic Planning and Policy Decision Support Tool for Urban Regions
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary In this paper we present a Decision Support System developed to assist urban designers, planners and policy makers to explore and evaluate possible urban layouts and their growth patterns. Thecore of the system consists of a modelling shell allowing the user to specify cellular automata based models of urban and regional systems. These models capture the effect of local spatial processes in which the use, or desired use of each parcel or cell of land is determined partly by institutional and environmental factors, and partly by the activities present in its neighbourhood. Since each cell affects every other cell within its neighbourhood, a complex dynamic emerges. Unlike conventional cellular automata, the models are defined with a large neighbourhood --over a hundred cells-- a relatively large number of states --more than a dozen in some applications-- representing socio-economic and natural land-uses. The approach permits the straightforward integration of detailed physical, environmental, and institutional constraints, as well as including the effects of the transportation and communication infrastructure. These models thus permit a very detailed representation of evolving spatial systems. The current version of the system represents urban areas as consisting of up to 10.000 interacting zones, each roughly the size of an individual city block. These models are easy to build and apply, yet empirical tests show that they produce realistic simulations of urban land use dynamics. Consequently, they are well suited to form the heart of the DSS, which provides the user with a number of tools for exploration,analysis and evaluation of alternative futures of the system as they result from policy interventions that are imposed by means of what-if experiments and scenario analysis. For example, the DSS isable to identify areas in which pressure for change in land use restrictions may become critical under particular development strategies. In the DSS, the modelling shell is coupled to a simple,custom-built GIS. In the stand-alone application of the DSS, this stores the detailed geographical qualities of the area being modelled, and allows basic overlay manipulations. It also displays theresults of the model while the simulation proceeds. Alternatively, the GIS can serve as aninterface to more elaborate, commercial GIS systems.

title Visualizing Simulated Construction Operations in 3D
source Journal of Computing in Civil Engineering -- October 2001 -- Volume 15, Issue 4, pp. 329-337
summary Simulation modeling and visualization can substantially help in designing complex construction operations and in making optimal decisions where traditional methods prove ineffective or are unfeasible.However, there has been limited use of simulation in planning construction operations due to the unavailability of appropriate support tools that can provide users with a more realistic and comprehensiblefeedback from simulation analyses. Visualizing simulated construction operations in 3D can significantly help in establishing the credibility of simulation models. 3D visualization can also provide valuableinsight into the subtleties of construction operations that are otherwise nonquantifiable and presentable. This paper describes the methodology and a first version of a general-purpose 3D visualization system thatis simulation and CAD software independent. This system, the Dynamic Construction Visualizer, enables spatially and chronologically accurate 3D visualization of modeled construction operations and theresulting products.

title A CAD Interface to Objective Assessment of Design to Support Decision Making in Urban Planning
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary The Department of Architecture at Edinburgh College of Art, Heriot Watt University, has an on-going project to create useful implementations of the method of spatial analysis called Space Syntax developed by Prof Bill Hillier at the Bartlett School of Architecture, London. Space Syntax can predict the potential usage of each route through an urban space or large building; some routes will be avoided by most traffic (pedestrian or vehicular), while other routes will become busy thoroughfares. It has been used by Architects and Urban Designers to support proposed developments, whether to show that potential commercial activity ought to be concentrated in an area of high traffic, or to change routes through troubled housing estates, bringing the protection of added traffic to areas previously avoided for fear of mugging. The paper describes how a specially written customized version of AutoCAD enables Post Graduate students of Urban Design and Undergraduate Architecture students to test their designs against the Space Syntax Measures. Simple interactive graphics enable plans to be entered and compared, so that plans may be evaluated during the design process, and decisions supported by objective tests. This improves both design decisions and the learning process, and should be useful to many professionals in urban planning.

source Architecture in the Network Society [22nd eCAADe Conference Proceedings / ISBN 0-9541183-2-4] Copenhagen (Denmark) 15-18 September 2004, pp. 342-348
summary The objective of this research was the analysis of a Canaletto painting that depicts Palladio’s plan for the „Convento della Carità“ in Venice, a plan that was only partially executed. Through the implementation of traditional techniques and digitally controlled instruments, the three dimensional model was reconstructed. It was compared with both Palladio’s original plan, and with the constructed version. A notable difference between the three projects emerged which allowed for a better comprehension- using photogrammetric restitution procedures- of Canaletto’s pictorial work and the corrections that the painter brought to the piece to improve the rendition of the painting. The study ends with an analysis of the natural light painted by Canaletto, and a simulation of sunlight with digital techniques.

title Mapping the City in Movement: The Car as an A/V Apparatus

summary “…our experience of the city, and hence our response to architecture, is almost exclusively conducted through the medium of the automobile: the car defines our space whether we are driving, being driven or avoiding being driven over. The car has been an integral part of metropolitan life for so long that it has become part of the urban fabric.” Jonathan Bell, Carchitecture. This DVD presents a series of audio/video mappings of the city in movement - an organizational condition which is derived from our car culture, a culture in movement. In these studies the digital audio/video camera, a device which allows us to explicitly record movement and change in time, is used as an investigative tool and as an extension of our bodies in order to observe, capture and measure otherwise imperceptible moments of our moving and fast paced experience of place. The projects are from a seminar/studio entitled A/V Mappings and Notations. This research looks at the merging of moving image and more conventional drawing to create maps which read physical and ephemeral conditions of place in an experiential and analytical manner. The importance of The Car as an A/V Apparatus studies is that they allow us to uncover characteristics of place that are particular to the infrastructure of our car cities and most importantly to the experience of inhabiting the transitory spaces of these cities in movement. The projects which will be presented extend the human body into the city via the car as an audio/video apparatus, an instrument for reading and measuring the city in movement. The documents are choreographed as sections through the city in which the section cut (the line drawn) is the trajectory of driving/drawing. In the making of these full-scale life size drawings, cameras are mounted to the car prior to driving. The location(s) of camera(s) are determined by the specifics of each investigation. What is choreographed is the set up of the car as an audio/video apparatus and of the trajectory of driving. The apparatus itself, the body/car/camera, in its trajectory captures, studies, measures, draws/drives. This as an extension of the human body allows us to detach ourselves from the dominance of our vision and to more objectively discover aspects of place as related to our movement and corporeal experience and otherwise hidden from our perception. In addition and more importantly as body/car/camera, the apparatus captures the city at the scale of driving (corpor/car) a scale which expands our body into the scale of a larger space of great distances, movements, speeds, and durations. The discoveries that these mappings reveal inform us of the potential for more specifically intervening in these cities with proposals which engage these two drastically different yet intricately connected scales.
