Abstract: We present actively procedural multiresolution paint textures. Texture elements may be linearly combined to create complex composite textures that continue to refine themselves when viewed at successively greater magnification. Actively procedural textures constitute a powerful drawing tool that can be used in a multiresolution paint system. They provide a mechanism to generate an infinite amount of detail with a simple and compact representation. We give several examples of procedural textures and show how to create different painting effects with them.
