An enhance framework on hair modeling and real-time animation
Maximizing visual effect is a major problem in real-time animation. One work was proposed on real-time hair animation based on 2D representation and texture mapping. Due to its 2D nature, it lacks of the volumetric effect as the real hair. This thesis presents a technique to solve the problem. The hair is still modeled in 2D strip. However, each visible strip is warped into U-shape for rendering after tessellation. Alpha and texture mappings are then applied to the polygon meshes of the U-shape. Note that the U-shape is not explicitly stored in the data structure. Because of the U-shape technique, we also adapt the collision detection and response mechanism in the former method. There are collisions between hair strips and other objects, e.g. scalp and shoulder, and the self-collisions of hair. Finally, a hair modeling function that is capable of modeling different hairstyles is also implemented.
