Though radiosity method is an advanced rendering technique of global illumination, it is still not sufficiently to cope with many natural phenonmena such as furry surfaces. The rendering of furry surfaces has been a long outstanding problem in image synthesis. Therefore, it is of significance to develop an approach to incorporate the rendering of furry surfaces into radiosity method. By combining the concept of texel with the furry radiosity map , established from the radiosity calculation based on the proposed furry form-factor in the paper, a new radiosity algorithm has been developed to produce the images of furry surfaces.
