In order to acquire a fast rendering of translucent materials via GPU (Graphic Processing Unit) rendering pipeline, we propose an effective method for realistic rendering based on improved diffusion equation and geometric feature sampling. Considering diffusion equation can simulate the complex subsurface scattering inside translucent materials, we improve and derive the diffusion equation as a discrete form to fit GPU evaluation easily. Using geometric features such as curvature and area, we

... prove classic Turk's point repulsion algorithm by the geometric feature sampling to spread out the sample points reasonably. The results show that our method could acquire a more realistic appearance by geometric feature sampling, better shading effect and relatively fast speed of rendering.
