title The Use of Genetic Programming In Exploring 3D Design Worlds - A Report of Two Projects by Msc Students at CECA UEL

summary Genetic algorithms are used to evolve rule systems for a generative process, in one case a shape grammar,which uses the "Dawkins Biomorph" paradigm of user driven choices to perform artificial selection, in the other a CA/Lindenmeyer system using the Hausdorff dimension of the resultant configuration to drive natural selection. (1) Using Genetic Programming in an interactive 3D shape grammar. A report of a generative system combining genetic programming (GP) and 3D shape grammars. The reasoning that backs up the basis for this work depends on the interpretation of design as search In this system, a 3D form is a computer program made up of functions (transformations) & terminals (building blocks). Each program evaluates into a structure. Hence, in this instance a program is synonymous with form. Building blocks of form are platonic solids (box, cylinder, etc.). A Variety of combinations of the simple affine transformations of translation, scaling, rotation together with Boolean operations of union, subtraction and intersection performed on the building blocks generate different configurations of 3D forms. Using to the methodology of genetic programming, an initial population of such programs are randomly generated,subjected to a test for fitness (the eyeball test). Individual programs that have passed the test are selected to be parents for reproducing the next generation of programs via the process of recombination. (2) Using a GA to evolve rule sets to achieve a goal configuration. The aim of these experiments was to build a framework in which a structure's form could be defined by a set of instructions encoded into its genetic make-up. This was achieved by combining a generative rule system commonly used to model biological growth with a genetic algorithm simulating the evolutionary process of selection to evolve an adaptive rule system capable of replicating any preselected 3D shape. The generative modelling technique used is a string rewriting Lindenmayer system the genes of the emergent structures are the production rules of the L-system, and the spatial representation of the structures uses the geometry of iso-spatial dense-packed spheres

title Collective Pavilions: A Generative Architectural Modelling for Traditional Chinese Pagoda
source Learning from the Past a Foundation for the Future [Special publication of papers presented at the CAAD futures 2005 conference held at the Vienna University of Technology / ISBN 3-85437-276-0], Vienna (Austria) 20-22 June 2005, pp. 129-138
summary This paper investigates generative architectural modelling for traditional Chinese architecture and aims to explore and extend the potential of adaptive computing for architectural design methods. The design manners analysis of traditional pagodas architectures is made in a holistic view and under historical perspective. We propose a descriptive model and generative system for the design of traditional Chinese pagodas, by which each pagoda is defined as a collection of style-matched and form-coordinated pavilions and described by both topological graphs and variant geometrical units. Our approach models both of the building geometry and space organization/spatial patterns of pagodas separately. The generative mechanism consists of a framework of grammar-based design and parametric, recursive shape computation. Accordingly, the generative algorithm is also made of two levels, the topology of spatial patterns and the shape geometrical parameters that characterize pavilion variations. The algorithm for computing the former is based on GP (Genetic Programming) and the latter GA (Genetic Algorithms). To explore the collective behaviour of a group of pavilions, multi-agent modelling approach is incorporated in composition patterns search. A prototype system, 'glPagoda', using the OpenGL graphics library for rendering and visualization, has been developed and implemented on PC windows platform.

title Technology-mediated process: case study--MIT Stata Center
source Fabrication: Examining the Digital Practice of Architecture [Proceedings of the 23rd Annual Conference of the Association for Computer Aided Design in Architecture and the 2004 Conference of the AIA Technology in Architectural Practice Knowledge Community / ISBN 0-9696665-2-7] Cambridge (Ontario) 8-14 November, 2004, 202-219
summary Gehry Partners’ (GP) sculptural approach to tectonic form, with its dramatic curves, complex geometry, and idiosyncratic application of materials, seems to have redefined the limits of architecture. The development of a strong formal vocabulary has been achieved by advanced use of information technologies, including CATIA, which allows translation among various tectonic representations, both in physical and digital forms. In addition, the nature of the office has much to do with other changes in the project delivery system, such as the relationships with associate architect, manufacturers, and subcontractors. This paper discusses how new technology changes the design and fabrication process, which has evolved from GP’s milestone project, Guggenheim Museum Bilbao, and how organizational efforts to involve the industry in the design process facilitate the project. Unlike at Bilbao, in the newly-completed Stata Center GP produced all the construction documents. This shift coincided with a gradual change in which GP was becoming involved in the technical aspects of their projects much earlier in the design process. Therefore they had to invest in new working relationships with the construction team, including fabricators, manufacturers, and contractors. The approach of Gehry and his team suggests that architectural practice can be liberated from its conventional arrangements. Although it is still evolving, Gehry has achieved a holistically integrated organizational system where the architect has far more direct interaction with all aspects of design and fabrication.

title AGENCY GP: Genetic Programming for Architectural Design
source Eternity, Infinity and Virtuality in Architecture [Proceedings of the 22nd Annual Conference of the Association for Computer-Aided Design in Architecture / 1-880250-09-8] Washington D.C. 19-22 October 2000, pp. 227-231
summary AGENCY GP is a prototype for a system using genetic programming (GP) for architectural design exploration. Its software structure is noteworthy for its integration into a high-end three-dimensional modeling environment, its allowance for direct user interruption of evolution and reintegration of phenotypically modified individuals, and its agent-based evaluation of fitness.

title Music Composition with Interactive Evolutionary Computation
source International Conference on Generative Art
summary Interactive Evolutionary Computation (IEC), i.e., Evolutionary Computation whose fitness function is provided by a user his/herself, has been applied to esthetic areas, such as art, design and music. We cannot necessarily define fitness functions explicitly in these areas. With IEC, however, we can embed the user's implicit preference into the optimization system. This paper describes a new approach to music composition, more precisely the composition of rhythms, by means of IEC. The main feature of our method is to combine Genetic Algorithms (GA) and Genetic Programming (GP). In our system, GA individuals represent short pieces of rhythmic patterns, while GP individuals express how these patterns are arranged in terms of their functions. Both populations are evolved interactively through the user's evaluation. The integration of interactive GA and GP makes it possible to search for musical structures effectively in the vast search space. In this paper, we show how successfully our proposed method can generate attractive musical rhythms. The effectiveness of our system is demonstrated by the evolved rhythm phrases, which are available from our web site as sound files.

title To CAAD or not to CAAD?
source SIGraDi 2004 - [Proceedings of the 8th Iberoamerican Congress of Digital Graphics] Porte Alegre - Brasil 10-12 november 2004
summary This paper reports a design experiment with first year.s students in two European countries .It reviews the role that computers can play in the early design stages and considers how far recent developments in commercial software have enabled designers to improve their design performance using CAAD systems. The authors are teaching architectural design in first and forth year in two European countries and are also involved in teaching Computer Aided Architectural Design. The starting point for our experiment was the fact that we realized that most of the students in our faculties still start their design with pen and paper. Although they introduce the computer quite early in the design process now their first design ideas were mainly visualized in sketches. Is this because of the often stated limitations of hard and software or because we start to teach them to sketch when we do design? This paper attempts to address some of the issues and find some answers.
