Based on the multi-layer textures approach, a new method of rendering real-time fur is proposed. The method takes full advantage of the new features of current Graphic Processing Units to compute the lighting of fur precisely and fast. More importantly, the self-shadow effect of fur and the soft shadow phenomenon over fur are simulated successfully, which enhances the rendering effects greatly. Experiments show that the method can deal with moderate models in real-time, which is very valuable for the applications of fur in many fields, such as cinema, video game and virtual reality etc.
