summary We would like to present some recent work using cellular automata and agent modelling for the generative design of building configurations. The cellular automata is based on a 3d terrain model of a site (taken from the recent Europan competition) which is encoded with both topological and economic data, and agents that are light sensitive and which reconfigure the developing architecture by checking overshadowing and spatial occupation. The emergent pattern of development therefore results from an understanding of the programmatic and the spatial parameters of the task, and is intimately related to the site and its peculiarities.

title Interactive Mapping between Knowledge Level and Symbol Level with Geometry. A KL-Model for Design Space Exploration
source Digital Design - Research and Practice [Proceedings of the 10th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-1210-1] Tainan (Taiwan) 13–15 October 2003, pp. 157-166
summary Design space exploration is long-standing motivating ideas in computer-aided design. It realises this vision through a model of design states for making and moving amongst states and an organisation of states into a structure called a design space. Using a design space structuring mechanism based on a subsumption relation, this paper sketches a theory called Geometric Typed Feature Structures (GTFS) to preserve the formal properties of the design space movement algorithms for geometry. It also provides the theory for incorporation of user-guided exploration in the design space. Consequently, the clear division between knowledge level and symbol level, such that functional decomposition •• formal symbol level and design •• model symbol level, disappears. We can therefore use the same subsumption relation to structure the design space exploration interactively. Such interactive mapping between knowledge level and symbol level provides the fine-grained opportunities for user intervention in formal design space movement algorithms. In this paper, we summarize this approach with an example of GTFS subsumption process.

summary The class of operations known as “undo” has proven to be a valuable addition to most professional work tools. In practice though, its use is frustrating: undo often undoes too much. Its essential informal semantics are that it returns the user to a prior state by recapitulating all intervening states. Why not give the user greater control over which aspects of a design to undo? An alternative is to seek to reuse prior work in any logically-coherent pattern—user input is a precious commodity. The area of generative systems provides insights in a search for alternatives to undo, in particular that prior user and system actions can be changed and reused in new contexts. We contingently introduce a concept we label as design promotions to describe system designs that demonstrate a tight coupling between interactive authorship and system-led generation, that treat past user actions as valuable intentional statements, and that treat alternative user choices as first-class objects of concern. In practice these three properties emphasize reuse. We briefly survey the current state of undo-like operations and potential candidates for implementing design promotions strategies. Through examples, we demonstrate approaches to realizing undo-like operations over specific representations, especially that of constructive solid geometry.

title A strategy for complex-curved building design:Design structure with Bi-lateral contouring as integrally connected ribs

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.

summary Purpose of this paper is to present the first promising results of an ongoing research program that is part of a larger multi-year project carried out by the Computer Aided Design Research Group (GRCAO) of the UniversitÈ de MontrÈal, in order to define new methods of archaeological restitution using computer-aided means. This novel approach involves a redefinition of surveying techniques, data processing and knowledge-based thinking in disciplines such as epigraphy and architecture. As its chosen field of investigation, the GRCAO is using the Egyptian temple of Karnak, a monument on the UNESCO World Heritage list that is of considerable historical importance. This impressive archaeological site serves as an excellent case study and testing ground for the project, since it underwent tremendous and complex architectural transformations in the course of its two thousand year-long history.

summary Where are we now?In the recent NJIT survey of digital media in the design schools twenty-eight out of twenty-nine architecture schools reported to have networked design studios (NJIT, 2003). This would seem to indicate a ubiquity of digital media tools. While the use of these tools is still often limited to design presentation (computer aided drawing and modeling) rather than design generation, the studio is historically a place of discovery and experimentation: with computers so available in this fertile environment we are poised to evolve the medium forward towards improved design development. This evolution is initially apparent in the way presentation methods and presentation processes are shifting. Not only are students becoming increasingly digital in their approach to design, but methods of working and presentation are also changing.

title Digital Exploration of Unbuilt Architecture: A Non-Photorealistic Approach
doi https://doi.org/10.52842/conf.acadia.2003.235
source Connecting >> Crossroads of Digital Discourse [Proceedings of the 2003 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-12-8] Indianapolis (Indiana) 24-27 October 2003, pp. 235-245
summary This paper presents a new approach to the digital investigation of unbuilt architecture. A navigable world, emulating the architect’s graphic style, is built as a 3D non-photorealistic reconstruction of the unbuilt project. A cinematic journey through this world intermediates the exploration of the architect’s possible mental visualizations during the creative stages. The goals of the proposed approach are: to open new avenues for investigating the conception of architecture, to help architectural students visualize and experience important unbuilt projects that have shaped the practice of architecture, and to popularize lesser-known architects to the general public. The approach stems from the idea that architectural drawings are the artifacts reflecting most accurately the architect’s creative and thinking processes. Anchored in the concept of multi-dimensional space developed by the author, the proposed method uses the original drawing of the artist as the main artifact on which the reconstruction process is based. The present paper concentrates on those aspects related to extracting information from the architect’s drawing and embedding historic knowledge in the 3D reconstruction of the unbuilt project. It calls to attention the idea that technological progress creates tools that the Architect uses to operate with the fundamental concepts of place, space, and time.

title Process and Individuation: Designing for Controlled Indeterminacy

summary Through the presentation of the design of a memorial, this paper intends to introduce an iterative design process that incorporates particle-based animation, parametrically constrained operations, and a variety of rapid-prototyping techniques. This is a project rooted in the generation and interpretation of physical artifacts dependent upon both the generative potential of digital media and the subjective modifications associated with design authorship It is stated in the brief for this ACADIA topic node that “the maturity of design, modeling, visualization, manufacturing and collaboration tools has allowed them to be naturally and comfortably integrated into the design process at all stages.” As such, the design statement for this memorial makes no mention of the incorporation of digital media. Process is subordinate to its result. Simply, the victims’ families would not find the range of technology incorporated in this design pertinent to the matter at hand: the design of a memorial to honor the victims of the attack on the Pentagon. Within the context of this “Digital Design” topic node, though, it is my intention to expose the digital underpinnings of this project and position it within a discourse somewhere between ars accidentalis and the constraints of fully parametric and geometrically-associative design.

summary Design space exploration is a long-standing focus in computational design research. Its three main threads are accounts of designer action, development of strategies for amplification of designer action in exploration and discovery of computational structures to support exploration. Chief amongst such structures is the design space - the network structure of related designs that are visited in an exploration process. There is relatively little research on design spaces to date. This paper sketches a partial account of the structure of both design spaces and research to develop them. It focuses largely on the implications of designers acting as explorers.
