Interactively evolving virtual environment maps with continuous layered pattern functions

Interactive aesthetic selection is used to evolve populations of images. The images are generated using continuous layered pattern functions which are based on procedural texturing techniques. Gene values are used to control the visual properties of regular and irregular layered feature patterns. A wide range of feature shapes is produced by implicit shape function blending and bombing. The evolved images are used to produce height fields which can be converted to multiuser game maps. The parametric design space defined by the chosen representation can be controllably biased toward specific formal qualities
