title Strategies for Interactive Design Systems
source 20 p. : ill. Pittsburgh, PA: Engineering Design Research Center, September, 1986. EDRC-48-02-87.
summary An information processing model of human problem solving is used to develop strategies for the design of systems for the interactive generation of designs. Systems of this type are currently not strongly developed anywhere, nor does there exist in the literature a paradigm for their creation. Design is a task which requires different interactive support than that traditionally provided by CAD systems. In this paper, those differences are uncovered by comparison of two tasks: one, named Definition in this paper, which seems to be well supported by existing systems; and the other, the task of Design. Use of an information processing model of human problem solving shows that differences between the tasks can be found in every potentially variant portion of the model. The information processing model is again used as a framework to propose mechanisms to support design. These mechanisms act by changing the underlaying phenomena upon which the information processing model is built and thus effecting changes, either parametric or structural, in the model. The relative importance of the proposed mechanisms is discussed, leading to the conclusion that the interactive support of search is the most strategic direction for future research

title VEGA : A Geometric Modelling System
source 11 p. : ill. Engineering Design Research Center, CMU, April 1986. DRC-48-03-87. includes bibliography
summary VEGA is a program which models rigid solid objects in three dimensions. Specifically, its domain is assemblies of planar faced polyhedra. VEGA supports a variety of operations to create, modify, query and delete these assemblies. VEGA is intended to serve two purposes: that of a new medium of representation for the design process; and of a programming package to support geometric applications in a wide variety of domains. Here the author addresses primarily the first of these purposes, that of a new medium for design. Designers of physical objects use an external medium, traditionally paper or physical models, not only to record their work, but to provide information which assists in the understanding of implications of design decisions. Designers proceed by performing operations, which reflect internal design decisions, on this external medium. The operations used in design are generally reflective of these physical media. For example, models built of clay tend to be formed by a subtractive processes, whereas models built of wood tend to be additive in nature. Designers who use drawings as their medium still tend to use operations which reflect operations on physical models. Computers provide the fascinating potential to provide a much wider variety of operations at a much greater speed than is available with the traditional means of representation. In addition, a computer based representation can provide quantitative information not easily accessible from traditional forms. This opens the potential for the inclusion of formal means of evaluation in the design process; something which is generally almost absent in traditional design teaching. A computer program which effectively and 'naturally' models physical objects and operations on them would be a valuable assistance to both the teaching and practice design. VEGA has been designed with these objectives in mind. VEGA represents physical objects with a scheme known as boundary representation and provides a wide variety of operations on these objects. VEGA also provides means to associate other, non-geometric, information with the objects it represents. VEGA is implemented under the ANDREW system. It communicates to ANDREW through a graphics package, also developed by the author's group. VEGA is intended to serve as a medium for future studio courses in the Architecture, Industrial Design and Arts education

title Variations in Solids : A Declarative Treatment
source Computers and Graphics. April, 1990. Vol. 14: 40 p. : ill. includes bibliography
summary Underlying the notions of variational geometry, design prototypes, features, and representation of assemblies seems to be a common concept of variations. This paper develops the core of a monotonically declarative system for variations on solids. It introduces a set of language constructs that are the basis for ASCEND, an object oriented equation solving language. It presents equations for representing certain spatial relationships between primitive geometric elements. Using plex grammar notation it develops a set of Euler operators that are monotonic in the strict sense required by the ASCEND language. These operators are collectively shown to generate representations for all plane models of 2-manifold objects and to generate only such representations. Finally it presents the core of a system for variations using the ASCEND language to implement both equation models and the new Euler operators

title The Future of Architectural Documentation: Harnessing Computational Design for Effective Project Delivery

Denver. 26-28 October 2023. edited by A. Crawford, N. Diniz, R. Beckett, J. Vanucchi, M. Swackhamer 154-163.
summary The Ocean Pavilion, located in Seattle, Washington (Figure 1), represents a contempo- rary case study of computation’s impact on effective communication and delivery of built architecture, and how these tools are questioning the habits of traditional architectural practice. A byproduct of a decade of applied research, the Ocean Pavilion illustrates a wide range of methods in which computational investigations have expanded the ability and capacity of the designers to effectively engage with consultants, contractors, and tradespeople, when compared to industry standards.Through the lens of four distinct design elements, this paper highlights moments of innovation, where computational tools and interoperability streamlined delivery of complex forms, proposed unconventional construction techniques, and enabled self-performed fabrication. With the Coral Canyon, a highly complex aquatic habitat located within the Ocean Pavilion, it navigates structural demands, rockwork and exhibit criteria, and advanced means and methods, in delivering a highly calibrated parametric model that becomes the single source of truth. Lessons learned there informed documentation for the exterior wood rainscreen, where tradi- tional architectural drawings proved inadequate in accurately communicating design intent. A third element internalizes the comprehensive design process, with the architect team self-performing fabrication. Lastly, the art soffit imbues the traditional crafts of an Indigenous Artist with computational know-how of the design team. Although differing in execution, underlying motives of collaboration and digital dissemination of knowledge are consistent throughout, offering a compelling story of computation’s impact on the Ocean Pavilion.

title Eliminating Redundant Primitives from Set- Theoretic Solid Models by a Consideration of Constituents
source 16 p. : ill. Winchester: IBM UK Scientific Center, IBM United Kingdom Laboratories Limited, April, 1988. IBM UKSC Report 188. includes bibliography
summary Set-theoretic solid models often contain redundant primitives, which slow down rendering and other processes. They are not simple to remove, especially as there can be alternative eliminations that may not be equally desirable. There has been recent progress towards solving this problem, but existing techniques for eliminating such redundant primitives do not fully consider the possibilities and rely on repeated evaluation of parts of the object's boundary, a process that is likely to be very slow. This article proposes a technique that allows alternative eliminations to be examined, and outlines a potentially efficient, but geometrically approximate, method of implementation

source 18 p. Winchester: IBM UK Scientific Center, IBM United Kingdom Laboratories Limited, January, 1988. IBM UKSC Report 183. includes bibliography
summary Existing computer-aided manufacturing systems are based on models of shape tailored to a particular process. Computer- integrated manufacture involves many different processes, and hence requires more complete models of components or assemblies. This can be provided by solid modelling techniques extended to include extra data related to manufacture such as form features and tolerances. These developments are being applied to many manufacturing processes, from casting to assembly, but profound questions remain concerning both the structure and the use of shape models in manufacture

title Splitting Set-Theoretic Solid Models into Connected Components
source 10 p. : ill. Winchester: IBM UK Scientific Center, IBM United Kingdom Laboratories Limited, June, 1989. IBM UKSC 210. includes bibliography In general, there is no way to tell how many pieces (connected components) a set-theoretic (CSG) solid model represents, except via conversion to a boundary model. Recent work on the elimination of redundant primitives has been linked with techniques for identifying connected components in quad-trees and oct-trees into a strategy to attack this problem. Some success has been achieved, and an experimental Prolog program, working in two dimensions, that finds connected components and determines the set-theoretic representation of each component, is reported, and further developments proposed.

April, 1982. pp. 89-95 : ill. includes bibliography.
summary A major problem with volume modelling systems is that processing times may increase with model complexity in a worse than linear fashion. The authors have addressed this problem, for picture generation, by repeatedly dividing the space occupied by a model, and evaluating the sub-models created only when they meet a criterion of simplicity. Hidden surface elimination has been integrated with evaluation, in such a way that major portions of the model which are not visible are never evaluated. An example demonstrates a better than linear relationship between model complexity and computation time, and also shows the effect of picture complexity on the performance of the process

summary We developed a synthetic environment design system which not only checks the design but can also create design in realtime. This is significant since there has yet been no existing tool that can accomplish such a task. Along with the development of the tool, we are currently refining the system by applying it to the China Qingdao Jiaonan City Environmental Design Project.

source Oxford: Blackwell
summary In Virtual Worlds, Benjamin Woolley examines the reality of virtual reality. He looks at the dramatic intellectual and cultural upheavals that gave birth to it, the hype that surrounds it, the people who have promoted it, and the dramatic implications of its development. Virtual reality is not simply a technology, it is a way of thinking created and promoted by a group of technologists and thinkers that sees itself as creating our future. Virtual Worlds reveals the politics and culture of these virtual realists, and examines whether they are creating reality, or losing their grasp of it.

source CAADRIA ‘97 [Proceedings of the Second Conference on Computer Aided Architectural Design Research in Asia / ISBN 957-575-057-8] Taiwan 17-19 April 1997, pp. 257-266
summary The role and importance of computer aided design for industrial design is growing. Computer modeling is increasingly in demand by clients because of the downstream benefits it can bring. The creation and manipulation of three dimensional form is central to an industrial designer during the design and development of new products. The paper addresses industrial design’s relationship with computer aided modeling, particularly three dimensional geometry. Design students and professionals have been observed using current computer aided design applications. Designers’ approaches and attitudes towards computer modeling have been identified. The future impact of computer aided modeling within industrial design activity and subsequent need for change, both in education and professional practice, are highlighted.

summary The material-based studies examine through computation and physical prototyping layered composites for thermal responsive building envelopes. Focus is placed on surveying and computing a large series of materials across four groups, for then to test these materials from factors of solar energy reception capacities, internal heating methods, heat isolation coatings and layer bonding. An oak-polyethylene structure is developed based on the first studies and further tested towards implementation as part of an adaptive envelope demonstrator, with these studies focused on fabrication and assembly methods. Results of the developed, tested and applied composite as part of an adaptive envelope shows that the environmental-material composite is strongly influenced by colour and direct solar radiation exposure. This in turn allow a material-fabrication approach to program a responsive system driven by exergy. Reinforcing the responsive reaction of the composite by internal heating does not advance the performance, as coatings are needed to maintain the heat inside the material, which adds weight and isolate the composite from the thermal environment that otherwise is intended to provide the energy for driving the responsive behaviour.

summary This research project investigates how glass from existing buildings can be extracted, redesigned and re-used through computational design and fabrication methods. Glass is a fundamental building component in the built environment, and at the same time the material with the highest environmental footprint per kg. With the current trend of a high glass-to-opaque building façade ratio, glass remains a central, important and problematic material for architecture. The studies are focused on experimental methods through material studies, computational studies and the making and observation of a full-scale demonstrator structure from harvested building glass. The method (water jet technology) proposed extracts around 90% of the glass, with the articulation method (sandblasting) providing significant transformation capabilities by re-designing the light, thermal and reflection properties with minimal removal of the material by computational models.

summary We have developed a modular approach to the parametric design of a patterned façade for tropical climates, using a “lighter” data set and model that integrates a number of performance considerations. This modular approach separates the façade's design into form, façade pattern, façade density requirements, and façade components, and reintegrates these aspects via a triangular mesh, represented as a fast and convenient data structure based on half-edges. Through this separation, the design team can simultaneously work on the architectural appearance of the design, its performance, and its fabrication, while retaining holistic control through the constant reintegration of design changes via the half-edge data structure. In this way, we retain the advantages of a parametrically driven design process, such as automatic design generation and the integration of performance aspects, while permitting more flexible and non-sequential design explorations by different members of the design team.

summary Increasing applications of parametric design and performance simulations by architectural designers present opportunities to design more resource- and energy-efficient buildings via simulation-based optimization. But Architectural Design Optimization (ADO) is less widespread that one might expect, due to, among other challenges, the problematic integration of optimization with architectural design. This problematic integration stems from a contrast between "wicked" or "co-evolving" architectural design problems and optimization problems. To mitigate the contrast between architectural and optimization problems, this paper presents Performance Explorer, an interactive, visual tool for performance-informed design space exploration (DSE). Performance-informed DSE emphasizes selection, refinement, and understanding over finding highest-performing design candidates. Performance Explorer allows interactive DSE via a visualization of a fitness landscape, with real-time feedback provided with a surrogate model. Performance Explorer is evaluated through a user test with thirty participants and emerges as more supportive and enjoyable to use than manual search and/or optimization.

summary This paper presents a novel method to visualize high dimensional parametric design spaces with applications in computational design space exploration. Specifically, the visualization method presented here supports the understanding of design problems in architectural design optimization by allowing designers to move between a high dimensional design space and a low dimensional "performance map". This performance map displays the characteristics of the fitness landscape, develops designers' intuitions about the relationships between design parameters and performance, allows designers to examine promising design variants and delineates promising areas for further design exploration.

By using the computer technique we designed a simulator program with environmental parameters and used this program to grow up a village. This village could be similar to the natural village and its space form will not only relate to physical environmental factor but also to local people's method of choosing the land.
