We will research biologically inspired computational models to develop new methods for computer creativity. The project aims to advance techniques for computer graphics modelling that can be applied to problems in the design and construction of rich, interactive visual environments. The systems we will construct allow the design of three-dimensional entities that develop and respond to their environment, a simulated ecosystem. The production of these virtual spaces has hitherto been difficult with existing technology. Our research provides a software tool capable of a broader range of expression than previous systems, and one that can be mastered by designers working with digital media.
