Abstract: In order to render realistic human face with fine skin structure, we present a novel method based on bump mapping. First of all, we project the normal map on facial model for each pixel of normal map represents a normal vector. Therefore, there are pixel-level normal vectors on the surface of facial model. Then, we disturb the normal vector using light vector and combine the result with facial color texture as color texture. Finally, we render the facial model with realistic textured skin and accidental characteristic.
