Abstract
We present a method to generate snow covers on complex scene geometries. Both volumetric snow shapes and photorealistic texturing are computed. We formulate snow accumulation as a diffusive distribution process on a ground scene. Our theoretical framework is motivated by models for granular material deposition. With the framework we can capture the most relevant features of natural snow cover geometries in a concise local computation scheme. Snow bridges and overhangs are also included. Snow surface texture coordinates are computed to create realistic ground–snow interfaces. Several example scenes and a supplementary snow cover growth animation demonstrate the method's efficiency.
