title	The Architecture of ScarCity Game - The craft and the digital as an alternative design process
doi	https://doi.org/10.52842/conf.ecaade.2019.3.045
source	Sousa, JP, Xavier, JP and Castro Henriques, G (eds.), Architecture in the Age of the 4th Industrial Revolution - Proceedings of the 37th eCAADe and 23rd SIGraDi Conference - Volume 3, University of Porto, Porto, Portugal, 11-13 September 2019, pp. 45-52
summary	The Architecture of ScarCity Game is a board game used as a pedagogical tool that challenges architecture students by involving them in a series of experimental design sessions to understand the design process of scarcity and the actual relation between the craft and the digital. This means "pragmatic delivery processes and material constraints, where the exchange between the artisan of handmade, representing local skills and technology of the digitally conceived is explored" (Huang 2013). The game focuses on understanding the different variables of the crafted design process of traditional communities under conditions of scarcity (Michel and Bevan 1992). This requires first analyzing the spatial environmental model of interaction, available human and natural resources, and the dynamic relationship of these variables in a digital era. In the first stage (Pre-Agency), the game set the concept of the craft by limiting students design exploration from a minimum possible perspective developing locally available resources and techniques. The key elements of the design process of traditional knowledge communities have to be identified (Preez 1984). In other words, this stage is driven by limited resources + chance + contingency. In the second stage (Post-Agency) students taking the architects´ role within this communities, have to speculate and explore the interface between the craft (local knowledge and low technological tools), and the digital represented by computation data, new technologies available and construction. This means the introduction of strategy + opportunity + chance as part of the design process. In this sense, the game has a life beyond its mechanics. This other life challenges the participants to exploit the possibilities of breaking the actual boundaries of design. The result is a tool to challenge conventional methods of teaching and leaning controlling a prescribed design process. It confronts the rules that professionals in this field take for granted. The game simulates a 'fake' reality by exploring in different ways with surveyed information. As a result, participants do not have anything 'real' to lose. Instead, they have all the freedom to innovate and be creative.

title	Computer-Aided Energy Economics for Early Concept Design Analysis
source	Building Economics, International Symposium Proceedings (3rd : Canada). 1984? vol. 3: pp.46-57 : ill. includes bibliography
summary	Decisions that have the greatest impact on energy cost performance are made very early in the design process. The problem is that these early design decisions are rarely tested thoroughly until very late in design. Usually this is due to the difficulties inherent in the use of the more sophisticated analysis procedures. Hourly energy computer simulations are costly to use, often require detailed input preparation, and use large ''main-frame' computers. Easier to use energy evaluation tools such as manual calculations and simplified computer programs do not yield reliable results. This is particularly true when passive solar design solutions are being tested. However, even the sophisticated approaches often have a limited ability to comprehensively model the economic implications of the more accurate energy simulations. This paper is intended to describe efforts at the University of Michigan to develop a more integrated approach to the assessment of energy economics - one that may be used at the earliest stages of concept design. The approach taken has been to concentrate on developing interactive, easy to use computer programs to describe building design proposals. This computer-generated building model is then used to automatically generate the information required to run a large, sophisticated energy analysis program developed by the U.S. Army Corps of Engineers (BLAST). Total life cycle cost analysis is performed either using procedures within BLAST or an 'electronic spreadsheet' system. Perceived deficiencies in the current state of this energy/cost evaluation system are described, and future research directions are presented

title	Digital Architecture in CAD studio and Internet-based competition
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	Architectural design has been changing because of the vast and creative use of computer in different ways. From the viewpoint of designing itself, computer has been used as drawing tools in the latter phase of design (Mitchell 1977; Coyne et al. 1990), presentation and simulation tools in the middle phase (Liu and Bai 2000), and even critical media which triggers creative thinking in the very early phase (Maher et al. 2000; Liu 1999; Won 1999). All the various roles that computer can play have been adopted in a number of professional design corporations and so-called computer-aided design (CAD) studio in schools worldwide (Kvan 1997, 2000; Cheng 1998). The processes and outcomes of design have been continuously developing to capture the movement of the computer age. However, from the viewpoint of social-cultural theories of architecture, the evolvement of design cannot be achieved solely by designers or design processes. Any new idea of design can be accepted socially, culturally and historically only under one condition: The design outcomes could be reviewed and appreciated by critics in the field at the time of its production (Csikszentmihalyi 1986, 1988; Schon and Wiggins 1992; Liu 2000). In other words, aspects of design production (by designers in different design processes) are as critical as those of design appreciation (by critics in different review processes) in the observation of the future trends of architecture.Nevertheless, in the field of architectural design with computer and Internet, that is, so-called computer-aided design computer-mediated design, or internet-based design, most existing studies pay more attentions to producing design in design processes as mentioned above. Relatively few studies focus on how critics act and how they interact with designers in the review processes. Therefore, this study intends to investigate some evolving phenomena of the interaction between design production and appreciation in the environment of computer and Internet.This paper takes a CAD studio and an Internet-based competition as examples. The CAD studio includes 7 master's students and 2 critics, all from the same countries. The Internet-based competition, held in year 2000, includes 206 designers from 43 counties and 26 critics from 11 countries. 3 students and the 2 critics in the CAD studio are the competition participating designers and critics respectively. The methodological steps are as follows: 1. A qualitative analysis: observation and interview of the 3 participants and 2 reviewers who join both the CAD studio and the competition. The 4 analytical criteria are the kinds of presenting media, the kinds of supportive media (such as verbal and gesture/facial data), stages of the review processes, and interaction between the designer and critics. The behavioral data are acquired by recording the design presentation and dialogue within 3 months. 2. A quantitative analysis: statistical analysis of the detailed reviewing data in the CAD studio and the competition. The four 4 analytical factors are the reviewing time, the number of reviewing of the same project, the comparison between different projects, and grades/comments. 3. Both the qualitative and quantitative data are cross analyzed and discussed, based on the theories of design thinking, design production/appreciation, and the appreciative system (Goodman 1978, 1984).The result of this study indicates that the interaction between design production and appreciation during the review processes could differ significantly. The review processes could be either linear or cyclic due to the influences from the kinds of media, the environmental discrepancies between studio and Internet, as well as cognitive thinking/memory capacity. The design production and appreciation seem to be more linear in CAD studio whereas more cyclic in the Internet environment. This distinction coincides with the complementary observations of designing as a linear process (Jones 1970; Simon 1981) or a cyclic movement (Schon and Wiggins 1992). Some phenomena during the two processes are also illustrated in detail in this paper.This study is merely a starting point of the research in design production and appreciation in the computer and network age. The future direction of investigation is to establish a theoretical model for the interaction between design production and appreciation based on current findings. The model is expected to conduct using revised protocol analysis and interviews. The other future research is to explore how design computing creativity emerge from the process of producing and appreciating.

title	Image and Shape: Two Distinct Approaches
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 410-415
summary	This paper is the result of two researches done at the district of Campeche, Florianópolis, by the Grupo PET/ARQ/UFSC/CAPES. Different aspects and conceptual approaches were used to study the spatial attributes of this district located in the Southern part of Santa Catarina Island. The readings and analysis of two researches were based on graphic pistures builded with the use of Corel 7.0 e AutoCadR14. The first research – "Urban Development in the Island of Santa Catarina: Public Space Study"- examined the urban structures of Campeche based on the Spatial Syntax Theory developed by Hillier and Hanson (1984) that relates form and social appropriation of public spaces. The second research – "Topoceptive Characterisation of Campeche: The Image of a Locality in Expansion in the Island of Santa Catarina" -, based on the methodology developed by Kohlsdorf (1996) and also on the visual analysis proposed by Lynch (1960), identified characteristics of this locality with the specific goal of selecting attributes that contributed to the ideas of the place its population held. The paper consists of an initial exercise of linking these two methods in order to test the complementarity of their analytical tools. Exemplifying the analytical procedures undertaken in the two approaches, the readings done - global (of the locality as a whole) and partial (from parts of the settlement) - are presented and compared.

title	Generative Housing Communities - Design of Participatory Spaces in Public Housing Using Network Configurational Theories
doi	https://doi.org/10.52842/conf.caadria.2020.2.283
source	D. Holzer, W. Nakapan, A. Globa, I. Koh (eds.), RE: Anthropocene, Design in the Age of Humans - Proceedings of the 25th CAADRIA Conference - Volume 2, Chulalongkorn University, Bangkok, Thailand, 5-6 August 2020, pp. 283-292
summary	This research-by-design project explores how public housing estates can accommodate social diversity and the appropriation of shared spaces, using qualitative and quantitative analysis of circulation networks. A case study housing estate in Hong Kong was analysed through field observations of movements and activities and as a site for the speculative re-design of shared spaces. Generative design processes were developed based on several parameters, including shortest paths, visibility integration and connectivity integration (Hillier & Hanson, 1984). Additional tools were developed to combine these techniques with optimisation of sunlight access, maximisation of views for residential towers and the provision of permeability of ground level building volumes. The project demonstrates how flexibility of use and social engagement can constitute a platform for self-organisation, similar to Jane Jacobs' notion of vibrant streets leading to active and progressive communities. It shows how computational design and configurational theories can promote a bottom-up approach for generating new types of residential environments that support participatory and diverse communities, rather than a conventional top-down approach that is perceived to embody mechanisms of social regimentation.

title	Neuromancer
source	Victor Gollancz
summary	Here is the novel that started it all, launching the cyberpunk generation, and the first novel to win the holy trinity of science fiction: the Hugo Award, the Nebula Award and the Philip K. Dick Award. With Neuromancer, William Gibson introduced the world to cyberspace--and science fiction has never been the same. Case was the hottest computer cowboy cruising the information superhighway--jacking his consciousness into cyberspace, soaring through tactile lattices of data and logic, rustling encoded secrets for anyone with the money to buy his skills. Then he double-crossed the wrong people, who caught up with him in a big way--and burned the talent out of his brain, micron by micron. Banished from cyberspace, trapped in the meat of his physical body, Case courted death in the high-tech underworld. Until a shadowy conspiracy offered him a second chance--and a cure--for a price....

title	Is Design Really Social
source	International Journal of Virtual Reality, 4:1
summary	There are many who will readily agree with Mitchell's assertion that "the most interesting new directions (for computer-aided design) are suggested by the growing convergence of computation and telecommunication. This allows us to treat designing not just as a technical process... but also as a social process." [Mitchell 1995]. The assumption is that design was a social process until users of computer-aided design systems were distracted into treating it as a merely technical process. Most readers will assume that this convergence must and will lead to increased communication between design participants, that better social interaction leads to be better design. The unspoken assumption appears to be that putting the participants into an environment with maximal communication channels will result in design collaboration. The tools provided, therefore, must permit the best communication and the best social interaction. We see a danger here, a pattern being repeated which may lead us into less than useful activities. As with several (popular) architectural design or modelling systems already available, however, computer system implementations all too often are poor imitations manual systems. For example, few in the field will argue with the statement that the storage of data in layers in a computer-aided drafting system is an dispensable approach. Layers derive from manual overlay drafting technology [Stitt 1984] which was regarded as an advanced (manual) production concept at the time many software engineers were specifying CAD software designs. Early implementations of CAD systems (such as RUCAPS, GDS, Computervision) avoided such data organisation, the software engineers recognising that object-based structures are more flexible, permitting greater control of data editing and display. Layer-based systems, however, are easier to implement in software, more familiar to the user and hence easier to explain, initially easier to use but more limiting for an experienced and thoughtful user, leading in the end to a lesser quality in resultant drawings and significant problems in output control (see Richens [1990], pp. 31-40 for a detailed analysis of such features and constraints). Here then we see the design for architectural software faithfully but inappropriately following manual methods. So too is there a danger of assuming that the best social interaction is that done face-to-face, therefore all collaborative design communications environments must mimic face-to-face.

source	1984. ii, 47 p. includes bibliography
summary	Computers have not been used in education in a way that fosters intellectual development of alternate approaches to design. Sufficient theory exists to use computing devices to support other potentially fruitful approaches to design. A proposal is made for the development of a computer system for architectural education which is built upon a particular model for design, that of rational decision making. Within the framework provided by the model, a series of courseware development projects are proposed which together with hardware acquisitions constitute a comprehensive computer system for architectural education

summary	The use of parametric curves and surfaces for object modeling in computer graphics is becoming increasingly popular. There is sometimes, however, a reluctance to use them because it seems that the added power they give is more than offset by the complexity of their formulations and their computations. The purpose of this article is to clarify their meanings and uses and show how much they have in common behind the diversity of their formulations. The author discusses the properties and benefits of using the parametric Hermite, Coons, Bezier, B-spline, and Beta-spline curve and surface formulations

summary	Different geometric structures are investigated in the context of discrete surface representation. It is shown that minimal representations (i.e., polyhedra) can be provided by a surface-based method using nearest neighbors structures or by a volume-based method using the Delaunay triangulation. Both approaches are compared with respect to various criteria, such as space requirements, computation time, constraints on the distribution of the points, facilities for further calculations, and agreement with the actual shape of the object

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.

summary	It has been proposed that a direct link between CAD and CAM be provided through a computer-automated process planning system. Described in this paper are algorithmic procedures to identify machined surfaces (i.e., machining requirements) for a workpiece directly from its 3D geometric description. A machined surface is a portion of workpiece that can be generated by a certain mode of metal removal operation. Machined surfaces are algorithmically recognized from a 3D boundary file, and then their 2 1/2D descriptions are obtained in a data structure (format) suitable for an automated process planning system. A simplified boundary file data structure is introduced in order to explain the machined surface recognition procedures
keywords	A machined surface type is defined as a pattern of faces, and a syntactic pattern recognition method is used to find the machined surface from the boundary file

title	Distributed Ray Tracing
source	Computer Graphics, vol. 18, no. 3, pp. 137145, July 1984. SIGGRAPH '84 Proceedings
summary	Ray tracing is one of the most elegant techniques in computer graphics. Many phenomena that are difficult or impossible with other techniques are simple with ray tracing, including shadows, reflections, and refracted light. Ray directions, however, have been determined precisely, and this has limited the capabilities of ray tracing. By distributing the directions of the rays according to the analytic function they sample, ray tracing can incorporate fuzzy phenomena. This provides correct and easy solutions to some previously unsolved or partially solved problems, including motion blur, depth of field, penumbras, translucency, and fuzzy reflections. Motion blur and depth of field calculations can be integrated with the visible surface calculations, avoiding the problems found in previous methods.

title	Building a Synthetic Cognizer
source	Design Computation Cognition conference 2004, MIT
summary	Understanding ‘space’ as a structured and dynamic system can provide us with insight into the central concept in the architectural discourse that so far has proven to withstand theoretical framing (McLuhan 1964). The basis for this theoretical assumption is that space is not a void left by solid matter but instead an emergent quality of action and interaction between individuals and groups with a physical environment (Hillier 1996). In this way it can be described as a parallel distributed system, a self-organising entity. Extrapolating from Luhmann’s theory of social systems (Luhmann 1984), a spatial system is autonomous from its progenitors, people, but remains intangible to a human observer due to its abstract nature and therefore has to be analysed by computed entities, synthetic cognisers, with the capacity to perceive. This poster shows an attempt to use another complex system, a distributed connected algorithm based on Kohonen’s self-organising feature maps – SOM (Kohonen 1997), as a “perceptual aid” for creating geometric mappings of these spatial systems that will shed light on our understanding of space by not representing space through our usual mechanics but by constructing artificial spatial cognisers with abilities to make spatial representations of their own. This allows us to be shown novel representations that can help us to see new differences and similarities in spatial configurations.

title	A Review of Solid Shape Modelling Based on Integrity
source	Computer Aided Design March, 1984. vol. 16: pp. 66-80 : ill. includes bibliography.
summary	The potential benefits of using a canonical model for representing the shapes of solid objects has led to the design and implementation of a number of geometric modelers with varying capabilities. This paper reviews the approaches taken in solid modeling by defining the well-formedness conditions which must be implemented in any modeling system. The methods for satisfying the well-formedness constraints in the various solid modeling methods are reviewed, using the concept of integrity constraints. The incorporation of integrity constraints, both explicitly and implicitly, into solid modelers are considered, with particular focus on boundary modelers. The use of integrity constraints for defining shape families and assembly families are also presented. The result is a unified view of solid shape modeling systems that enables their classification and extension into particular application areas

title	Smalltalk-80: The Interactive Programming Environment
source	Reading, MA: Addison-Wesley
summary	This book describes the process by which Smalltalk was introduced to people outside Xerox PARC, where it was developed. This book first describes the incredibly exciting history of how Smalltalk was built from scratch. It then goes on to show the way in which Smalltalk was made public. At first, this was an engineering process. Large companies were contacted and offered to participate by porting the Smalltalk VM to their machines, and then running an image provided on tape. Each of these teams then wrote a paper on their experience, and these original papers are included in this book. Xerox PARC also wrote its own paper. These papers are an invaluable source of information for any Smalltalker. They range from overall design issues down to statistics on the work of the VM and image contents.

source	II Seminario Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings / ISBN 978-97190-0-X] Mar del Plata (Argentina) 9-11 september 1998, pp. 274-279
summary	TDE is a graphic language capable of notation of pure design operations, which offers an alternative to Monge and Perspective drawing. This language which was perfected and developed by Claudio Guerri in the late 80's, is originated in the Theory of Spatial Delimitation of CÈsar Janello (1974-1984). From 1995 onwards, and within the framework of the UBACyT AR025 Project (1995-1997), a software in order to apply the TDE through computer technology started to be developed. This work is carried out within the framework of the research program SPATIAL SEMIOTICS-DESIGN THEORY of the FADU-UBA directed by Claudio Guerri, and is continued in the UBACyT AR01 4 Project (1998-2000) "TDE-AC.
