Animated Texels

Abstract

Volumetric texturing is a method dedicated to modeling complex repetitive geome-tries, such as grass, fur or foliage, by storing a volumetric sample to be mapped on a surface. This representation is effective in a ray-tracing environment, giving images with low aliasing at low cost. We show here that it can be extended to get an easy way of animating complex repetitive geometries, like the effects produced by the wind in a wheat field, or fur motions.
