title	Design with space syntax analysis based on building information model: Towards an interactive application of building information model in early design process

summary	This paper introduces a new framework to enable user-friendly space syntax analysis during the initial design stage. It assists designers, without in-depth knowledge on space syntax, to evaluate and compare design outcomes rapidly. The framework is realized by integration between space syntax and building information model in which space topology is autonomously retrieved. A BIM modeler so called ‘ArchiSpace’ has been developed to demonstrate the applicability of the framework to design practice. Our experiment shows that designers can use the modeler to analyze their design alternatives instantly at any moment during the initial design stage. Therefore, users can generate and evaluate their design alternatives simultaneously without distraction and tedious work on the space syntax analysis in detail.

title	Virtual Organism: Generative Tool Based on Multi-Agent System
doi	https://doi.org/10.52842/conf.caadria.2009.625

summary	A multi-agent system (MAS) is efficient as it can emulate a variety of organisms in natural science due to the interactions between agents, which make artificial systems responsive and adaptive. In “Bamboo Workshop” involved flexible structures, MAS was employed to create virtual organism in computational environment towards an innovative process in installation design. A generative tool with friendly user interface was developed for both observation and intervention besides debugging. At the same time investigations were carried on the complex behaviours of the system through graphic statistics. Integrated with the generative tool, a construction system made up of bamboo materials was set up to build a series of mobile and flexible installations. This experiment suggests that the virtual organism has the potential for being a part of the design intelligence, beyond a mere digital tool.

title	Editing Shapes in a Prototype Two- and Three-dimensional Shape Grammar Environment
doi	https://doi.org/10.52842/conf.ecaade.2009.243
source	Computation: The New Realm of Architectural Design [27th eCAADe Conference Proceedings / ISBN 978-0-9541183-8-9] Istanbul (Turkey) 16-19 September 2009, pp. 243-250
summary	Recently we developed a prototype general shape grammar system, called Grammar Environment (Li et al. 2009). It differs from other systems in that it aims to support designers who design with shape grammars. One task of such a system is to support users in editing shapes. The guidelines that we followed in developing Grammar Environment suggested that the shape editing system should both be integrated into the system and be powerful as a drawing tool. This seemed to be contradictory. We decided to make two shape editors: one stronger on integration, the other on drawing power.

title	A Prototype System for developing two- and Three-Dimensional Shape Grammars
doi	https://doi.org/10.52842/conf.caadria.2009.717
source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 717-726
summary	A number of researchers have developed shape grammar systems, with a variety of aims. These systems all help users (to varying degrees) to run grammars, but not to develop grammars. However, we believe that developing grammars is also work and needs to be supported. A system to do this would make it easier and more convenient for people using grammars to do design work. Following the generate-test model, we design and implement a prototype system that supports the user in editing grammars, testing grammars, and switching easily between the two types of activity. We emphasize the graphic nature of the task: the user is all the time working with graphic objects, namely shapes.

title	Optimal Organization of Architectural Spaces Based on Genetic Algorithm
doi	https://doi.org/10.52842/conf.caadria.2009.653
source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 653-661
summary	Genetic algorithms categorized as global search heuristics are search technique of seeking approximate or exact solutions for optimizing problems. Our generative tool named notchSpace starts from a population of randomly generated individuals which rationally subdivide architectural spaces with a low “fitness”. During generations’ evolution, the population is recombined, modified and mutated at a low rate to form new modes of building spatial subdivision; a new population is used in the next iteration. NotchSpace works up a research platform to evolve architectural spaces, and it explores the thinking of translation from computer algorithms to the field of architecture.
