title	Training Programs for Art and Design Learning in the Virtual Studio
source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 639-646

summary	Computers are very common drawing tools at university design studios but their potential as training tools in arts and design has not been explored in depth. In arts and design the learning process is based on ‘knowing in action’ (Schön 1983). Therefore, training is the keystone of the learning process in arts and design. This action takes the form of a reflective practice based on the manipulation of a media where each media has its own possibilities, its own limits in communicating design ideas or artistic concepts. With the introduction of digital media in the design studio, it is expected that reflective practices in design learning will experience a qualitative change. However, currently there is little understanding of how to use the digital and virtual media in a design studio as a learning tool (Szalapaj 2001), nor of the use of design training programs. In this paper the use of training programs in an experimental design course at a university level, is discussed. This experience was carried out as a PhD research experiment at the Faculty of Architecture and Arts of the Universidad de Los Andes in Merida, Venezuela. The training programs discussed here were designed for an eight week introductory design course in a virtual design studio. The programs were written in VRML and conceived as a virtual design training environment. Each program was designed for a specific design exercise, based on a learning strategy and an interactivity model proposed for object manipulation in design training. A comparative analysis of the data gathered from the course was made of training exercises done with a Cad program and with the training programs and crossing information with other sources. The experiment shows that the training programs, their learning strategy and the interactivity model proposed were successful in guiding the scope of the design exercises during the training process.

title	Disjunctive Programming and a Hierarchy of Relaxations for Discrete Optimization Problems
source	December, 1983. 38 p. : ill. includes bibliography
summary	The author discuss a new conceptual framework for the convexification of discrete optimization problems, and a general technique for obtaining approximations to the convex hull of the feasible set. The concepts come from disjunctive programming and the key tool is a description of the convex hull of a union of polyhedra in terms of a higher dimensional polyhedron. Although this description was known for several years, only recently was it shown by Jeroslow and Lowe to yield improved representations of discrete optimization problems. The author expresses the feasible set of a discrete optimization problem as the intersection (conjunction) of unions of polyhedra, and define an operation that takes one such expression into another, equivalent one, with fewer conjuncts. He then introduces a class of relaxations based on replacing each conjunct (union of polyhedra) by its convex hull. The strength of the relaxations increases as the number of conjuncts decreases, and the class of relaxations forms a hierarchy that spans the spectrum between the common linear programming relaxation, and the convex hull of the feasible set itself. Instances where this approach presents advantages include critical path problems in disjunctive graphs, network synthesis problems, certain fixed charge network flow problems, etc. The approach on the first of these problems is illustrated, which is a model for machine sequencing

title	Gaming Simulation: A Communication Tool for Architects and Designers
source	University of Michigan
summary	In today's technological society, people spend more and more time in built environments that they have little or no control in shaping. There is also a large gap in communication between designers of the built environment and non-designers. The language that non-designers use to communicate specific spatial needs, whether aesthetic or functional, is different from the formal language that designers use to communicate these issues with each other. Gaming simulation, as a communication tool, has a number Note of characteristics that make it useful for improving communication and increasing participation among designers and non-designers. In this study, a method of teaching the design of gaming simulation to designers of the built environment is developed. This method includes a Game Design Index or cataloging system of gaming tehniques, within the context of a game design process. A questionnaire was used to interview the designers of the most current physical design games about the gaming techniques in their games. Their answers were organized into the Game Design Index and set within the context of a process for designing a game. This process was tested by teaching a course to graduate students in Urban Planning and Architecture. Further testing was done by holding a game design workshop for professional architects. The findings indicate that it is possible to analyze existing games for their gaming techniques and to index them in an organized way. It is also possible to add this index to an existing game design process. By using this process, graduate students were able to design gaming simulations of high quality, although professionals who attended a day-and-a-half workshop, were not so successful. This latter problem was primarily the result of the complexity of the task and the time constraint imposed. This dissertation describes the game design process that was used to teach neophytes to design games as well as the Game Design Indexes for ten existing games. A comprehensive review of games concerned with physical design is included

title	An Automatic Algorithm Designer : An Initial Implementation
source	Design Research Center, CMU, May, 1983. 10 p. includes bibliography
summary	This paper outlines a specification for an algorithm-design system (based on previous work involving protocol analysis) and describes an implementation of the specification that is a combination frame and production system. In the implementation, design occurs in two problem spaces: one about algorithms and one about the task domain. The partially worked out algorithms are represented as configurations of data-flow components. A small number of general purpose operators construct and modify the representations. These operators are adapted to different situations by instantiation and means-ends analysis rules. The data-flow space also includes symbolic and test-case execution rules that drive the component-refinement process by exposing both problems and opportunities. A domain space about geometric images supports test-case execution, domain-specific problem solving, recognition and discovery

summary	Students currently in schools of architecture will be at the peak of their careers around the year 2000. The pressure on the schools to provide an education and training which will stand the student in good stead between now and then is considerable. In an increasing number of departments of architecture and building science, importance is being placed on the concept of modelling: i.e. the development and use of models of the operational behaviour and aesthetic character of design proposals which will allow appraisal of how real buildings will performing the real world.

title	Solution of Constrained Generalized Transportation Problems Using the Pivot and Probe Algorithm
source	17 p. Pittsburgh PA: Design Research Center, CMU, December, 1983. DRC-70-17-83. includes bibliography
summary	In this paper the authors use a specialized version of their Pivot and Probe algorithm to solve generalized transportation problems with side constraints. The dual of an m x n generalized transportation problem with t side constraints is a linear program with m + n + t variables and up to m x n constraints. They solve the dual problem using the probe operation to select only the most important constraints to consider. Also presented is a computational experience on problems of sizes up to 180 x 180, having various degrees of density and having as many as 10 side constraints. It was found that for a given size and density, problems become harder to solve as the number of side constraints increases. Ô h)000*°° ÔŒ Also, for a fixed number of side constraints, the solution difficulty increases with size and density. The authors found that their method was able to solve problems of the quoted sizes relatively quickly, with relatively few pivots, and without using basis reinversion

title	CAAD: Shorter-term Gains; Longerterm Costs?
source	Computer-Aided Architectural Design Futures [CAAD Futures Conference Proceedings / ISBN 0-408-05300-3] Delft (The Netherlands), 18-19 September 1985, pp. 185-196
summary	Assessment of CAAD systems in use is complex: it needs careful qualifications and is often contradictory. It is suggested that little progress has been made in making sense of the impacts of computing on design and design organizations. Impacts are more diverse and complicated than has been assumed. Assessments tend to be either overtly optimistic or pessimistic, yet the need is to be realistic. Moreover, impacts have been the subject of speculation and marketing rather than systematic study. Carefully documented case studies of projects or longitudinal studies of organizational impacts remain the exception. This chapter draws upon recorded user experience reported elsewhere (Walters, 1983)' and presents an assessment of the performance in use of current production systems. It presents an end-user view and also identifies a number of outstanding design research topics It is suggested that different systems in different organizations in different settings will give rise to new impacts. A wide variety of outcomes is possible. It seems unlikely that any simple set of relationships can account for all the data that inquiry reveals. The task becomes one of identifying variables that lead to differential outcomes, as the same cause may lead to different effects (Attewell and Rule, 1984). This becomes a long-term task. Each optimistic impact may be countered by some other more pessimistic impact. Moreover, the changes brought about on design by computing are significant because both beneficial and non- beneficial impacts are present together. Impacts are held in a dynamic balance that is subject to constant evolution. This viewpoint accounts for otherwise conflicting conclusions. It is unlikely that the full range of impacts is yet known, and a wide range of impacts and outcomes already need to be taken into account. It seems that CAD alone cannot either guarantee improved design or that it inevitably leads to some diminished role for the designer. CAD can lead to either possible outcome, depending upon the particular combination of impacts present. Careful matching of systems to design organization and work environment is therefore needed. The design management role becomes crucial.

title	A Dynamic Space-Time Network Flow Model for City Traffic Congestion
source	43 p. : ill. graphs Pittsburgh, PA: Design Research Center CMU, December, 1983. DRC-70-18-83. includes bibliography
summary	A space-time network is used to model traffic flows over time for a capacitated road transportation system having one-way and two-way streets. Also traffic signal lights, which change the network structure, are explicitly incorporated into the model. A linear (time) cost per unit flow is associated with each arc, and it is shown that under the model structure, travel time on a street is piecewise linear convex function of the number of units travelling on that street. Hence congestion effects are explicitly considered while maintaining the linear nature of the model. Two efficient solutions methods are proposed. A network flow solution for multiple source single destination network and a shortest path solution for a single source single destination network

title	A digital Procedure of Building Construction: A practical project
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 earlier times in which computers have not yet been developed well, there has been some researches regarding representation using conventional media (Gombrich, 1960; Arnheim, 1970). For ancient architects, the design process was described abstractly by text (Hewitt, 1985; Cable, 1983); the process evolved from unselfconscious to conscious ways (Alexander, 1964). Till the appearance of 2D drawings, these drawings could only express abstract visual thinking and visually conceptualized vocabulary (Goldschmidt, 1999). Then with the massive use of physical models in the Renaissance, the form and space of architecture was given better precision (Millon, 1994). Researches continued their attempts to identify the nature of different design tools (Eastman and Fereshe, 1994). Simon (1981) figured out that human increasingly relies on other specialists, computational agents, and materials referred to augment their cognitive abilities. This discourse was verified by recent research on conception of design and the expression using digital technologies (McCullough, 1996; Perez-Gomez and Pelletier, 1997). While other design tools did not change as much as representation (Panofsky, 1991; Koch, 1997), the involvement of computers in conventional architecture design arouses a new design thinking of digital architecture (Liu, 1996; Krawczyk, 1997; Murray, 1997; Wertheim, 1999). The notion of the link between ideas and media is emphasized throughout various fields, such as architectural education (Radford, 2000), Internet, and restoration of historical architecture (Potier et al., 2000). Information technology is also an important tool for civil engineering projects (Choi and Ibbs, 1989). Compared with conventional design media, computers avoid some errors in the process (Zaera, 1997). However, most of the application of computers to construction is restricted to simulations in building process (Halpin, 1990). It is worth studying how to employ computer technology meaningfully to bring significant changes to concept stage during the process of building construction (Madazo, 2000; Dave, 2000) and communication (Haymaker, 2000).In architectural design, concept design was achieved through drawings and models (Mitchell, 1997), while the working drawings and even shop drawings were brewed and communicated through drawings only. However, the most effective method of shaping building elements is to build models by computer (Madrazo, 1999). With the trend of 3D visualization (Johnson and Clayton, 1998) and the difference of designing between the physical environment and virtual environment (Maher et al. 2000), we intend to study the possibilities of using digital models, in addition to drawings, as a critical media in the conceptual stage of building construction process in the near future (just as the critical role that physical models played in early design process in the Renaissance). This research is combined with two practical building projects, following the progress of construction by using digital models and animations to simulate the structural layouts of the projects. We also tried to solve the complicated and even conflicting problems in the detail and piping design process through an easily accessible and precise interface. An attempt was made to delineate the hierarchy of the elements in a single structural and constructional system, and the corresponding relations among the systems. Since building construction is often complicated and even conflicting, precision needed to complete the projects can not be based merely on 2D drawings with some imagination. The purpose of this paper is to describe all the related elements according to precision and correctness, to discuss every possibility of different thinking in design of electric-mechanical engineering, to receive feedback from the construction projects in the real world, and to compare the digital models with conventional drawings.Through the application of this research, the subtle relations between the conventional drawings and digital models can be used in the area of building construction. Moreover, a theoretical model and standard process is proposed by using conventional drawings, digital models and physical buildings. By introducing the intervention of digital media in design process of working drawings and shop drawings, there is an opportune chance to use the digital media as a prominent design tool. This study extends the use of digital model and animation from design process to construction process. However, the entire construction process involves various details and exceptions, which are not discussed in this paper. These limitations should be explored in future studies.

title	A strategy for complex-curved building design:Design structure with Bi-lateral contouring as integrally connected ribs
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 465-469
summary	Shapes in designs created by architects such as Gehry Partners (Shelden, 2002), Foster and Partners, and Kohn Peterson and Fox rely on computational processes for rationalizing complex geometry for building construction. Rationalization is the reduction of a complete geometric shape into discrete components. Unfortunately, for many architects the rationalization is limited reducing solid models to surfaces or data on spread sheets for contractors to follow. Rationalized models produced by the firms listed above do not offer strategies for construction or digital fabrication. For the physical production of CAD description an alternative to the rationalized description is needed. This paper examines the coupling of digital rationalization and digital fabrication with physical mockups (Rich, 1989). Our aim is to explore complex relationships found in early and mid stage design phases when digital fabrication is used to produce design outcomes. Results of our investigation will aid architects and engineers in addressing the complications found in the translation of design models embedded with precision to constructible geometries. We present an algorithmically based approach to design rationalization that supports physical production as well as surface production of desktop models. Our approach is an alternative to conventional rapid prototyping that builds objects by assembly of laterally sliced contours from a solid model. We explored an improved product description for rapid manufacture as bilateral contouring for structure and panelling for strength (Kolarevic, 2003). Infrastructure typically found within aerospace, automotive, and shipbuilding industries, bilateral contouring is an organized matrix of horizontal and vertical interlocking ribs evenly distributed along a surface. These structures are monocoque and semi-monocoque assemblies composed of structural ribs and skinning attached by rivets and adhesives. Alternative, bi-lateral contouring discussed is an interlocking matrix of plywood strips having integral joinery for assembly. Unlike traditional methods of building representations through malleable materials for creating tangible objects (Friedman, 2002), this approach constructs with the implication for building life-size solutions. Three algorithms are presented as examples of rationalized design production with physical results. The first algorithm [Figure 1] deconstructs an initial 2D curved form into ribbed slices to be assembled through integral connections constructed as part of the rib solution. The second algorithm [Figure 2] deconstructs curved forms of greater complexity. The algorithm walks along the surface extracting surface information along horizontal and vertical axes saving surface information resulting in a ribbed structure of slight double curvature. The final algorithm [Figure 3] is expressed as plug-in software for Rhino that deconstructs a design to components for assembly as rib structures. The plug-in also translates geometries to a flatten position for 2D fabrication. The software demonstrates the full scope of the research exploration. Studies published by Dodgson argued that innovation technology (IvT) (Dodgson, Gann, Salter, 2004) helped in solving projects like the Guggenheim in Bilbao, the leaning Tower of Pisa in Italy, and the Millennium Bridge in London. Similarly, the method discussed in this paper will aid in solving physical production problems with complex building forms. References Bentley, P.J. (Ed.). Evolutionary Design by Computers.

title	VEGA : A Geometric Modelling System
source	11 p. : ill. December, 1983. DRC- 48-04-83. includes bibliography
summary	VEGA is an interactive geometric modelling system which has been developed at Carnegie-mellon University primarily for education in architecture and the arts. Its educational use is twofold: first as a medium for description and manipulation of form to aid in creative work and second as a base package of procedures that may be used by advanced architecture students in the creation of specialized modelling packages. VEGA is written in PASCAL. There are versions of VEGA currently running on VAX 11/780 computer under the UNIX and VMS operating systems. VEGA has been designed to run on a stand-alone personal computer. Currently VEGA is being converted to run on Sun Microsystems and PERQ machines. VEGA is used in the undergraduate curriculum of the School of Architecture at Carnegie-Mellon University. Its primary use to date has been as a means to introduce geometric modelling to architecture students who have minimal computer experience. VEGA may be viewed as a complete geometric modelling package or as a programming aid for development of special purpose geometric modelling programs. To date, one such specialized system, a robot arm design package, has been created as a student project. The development of the VEGA system is continuing. Current areas of interest include the development of more powerful geometric operations on polyhedra, parametric shapes and assemblies, instancing of sub- assemblies, user definition of primitive shapes and an interactive macro language for the manipulation of form

summary	The approach of devising robust surface methods applicable to arbitrarily located data was taken by the CAGD Group at the University of Utah. Adopting two broad classes of methods suitable for solving the problems (i.e., problems for which simplifying geometric assumptions cannot be made): (1) surface interpolants defined over triangles or tetrahedra and (2) distance-weighted interpolants. Interactive computer graphics was used to display surfaces for adequate visualization. Although some figures were given, it must be kept in mind that some 3-D medium, or at least motion, is necessary to understand surfaces

doi	https://doi.org/10.52842/conf.ecaade.1983.x.n2m
summary	We describe a computer program VOLUME for interactive 3D modelling of building which can be used in many problems (heat losses calculations, architectural evaluation, ...) where a geometric representation is required. The program is more than a tool to input a geometry: it is also a tool for design; manipulations are very easy and many design solutions can be tried. We then discuss about developments for improving the quality of that tool in the design process.

doi	https://doi.org/10.52842/conf.ecaade.1983.x.t5s
summary	Any great expansion of the population of computer users, embracing architects and other ordinary people, will happen only if we change from current computing technology to radically new software technology. Criteria for new technology are discussed, with reference to inadequacies of current technology; we should strive for computers that can understand people. Logic programming is described as one development towards this goal, illustrated by the example of Prolog serving as interpreter of user demands and supporting partial and changing logical models of user activity. Architects can choose computing options now that will put them on a path leading to future new technology. Choice is explained, favouring a software environment that is used by researchers and also supports immediate and practical computer applications. Lessons are drawn for architectural education, to prepare for change that will take place during a student's 40-year working life.

summary	While the basic ideas of frame systems are straight forward, complication arise in their design. A design strategy was developed and have been implemented in a representation system called Krypton.
