Lee, H.C., Tang, M.X. (2004). Evolutionary shape grammars for product design. In: Generative Art 2004.



This paper describes the development of a product design support system based on a framework of shape grammars enhanced by evolutionary computing. In this research, the forms of a product are analysed to derive shape features in the form of shape grammar rules. The rules are then encoded as the code scripts of a genetic algorithm in order to generate new shape grammar rules. The results generated by the genetic algorithm define a new combination of shape features for alternative designs. In this way, traditional shape grammar is extended to an interactive context in which generative and evolutionary computing methods are combined. Both product component design as well as product configuration are supported in this framework.
