GPU-based Realistic Fur Rendering

This paper presents a realistic fur rendering method based on GPU acceleration. The method represents furry effect by rendering multi-layer, semi-transparent textured slices, and takes full advantage of programmable ability of GPU in the rendering process. The GPU's Vertex shader is used to compute the geometry positions of multi-layer meshes, and the Pixer shader is used to compute the special lighting effect of fur. Experimental results show that the rendering efficiency is improved remarkably by using GPU-based method. This method can achieve real-time rendering rates for the models with moderate number of polygons, and the rendering results are good.
