Abstract: The isolated styling constraints are commonly used in existing hairstyle modeling, and these methods may not work when the hairstyle to be built is complicated enough. Due to the characteristic of layered and stage-by-stage de- formation along hair strand, a method of hairstyle modeling with layered multistage constraint domain was presented, by which various of complicated hairstyles can be built with styling constraints interactively. Through the establishment of global and local styling constraint queue on hair wisp, more constraints can be used to generate complicated hair strand deformation properly. Moreover, the rotation minimizing frames (RMF) of hair strand and user-defined parametric c- quations of space spiral are combined to add more detailed appearance. The experiment result shows that rich and natu- ral hairstyle can be built with the method proposed effectively.
