Furry surface modeling and rendering technique is a difficult problem in computer graphics.It is very hard to obtain satisfactory results for hairstyles through traditional modeling and rendering techniques,because of the fine shapes and the huge amount of human hairs.The concept of curly volumetric textures is first presented and expressed for hairs in this paper.With reference to the process of barber's hairstyle making,scalp surface is specially processed,based on the shape of human head,a simple modeling method is given for hairstyles.Then the head surface is processed and converted to a polyhedron of quadrilaterals of neighboring relationships,and the simple modeling method is modified and developed with interpolation method.Some examples of hairstyle modeling are given.The images of hairstyles are rendered with comparatively realistic effects at last.
