The Genetic Sculpture Park seeks to engage artists and observers in a creative dialogue and to empower novices in the creation of complex computer-graphic models. Each visitor to the park experiences a unique set of sculptural forms and takes part in a cooperative conversation with the computer to produce more aesthetically pleasing designs. Inspired by Darwin's theory of evolution, the project uses genetic algorithms to allow visitors to “breed” forms tailored to their individual sense of aesthetics. In this article, the authors recount investigations into evolutionary design methodologies (using shampoo bottles and three-dimensional head models) and describe their implementation in the Genetic Sculpture Park, an interactive Java/Virtual Reality Modeling Language (VRML) world.
