摘　　要：Generation of photo-realistic images of human hair is a challenging topic in computer graphics. The difficulty in solving the Problem in this aspect comes mainly from the extremely large number of hairs and the high complexity of the hair shapes. Regarding to the modeling and rendering of hair-type objects, Kajiya proposed a so-called texel model for producing furry surfaces. However, Kajiya's model could be only used for the generation of short hairs. In this paper, a concise and practical approach is presented to solve the problem of rendering long hairs, and in particular the method of rendering the smooth segmental texels for the generation of long hairs is addressed.Generation of photo-realistic images of human hair is a challenging topic in computer graphics.
