碩士 === 國立交通大學 === 多媒體工程研究所 === 97 === Simulating hair motion is difficult due to their high-stiffness property, which usually causes numerical stability problem and needs the numerical simulation be performed at a small time step. We observed that a force applied to one part of a strand will transport to other parts of the strand where the force can contribute the deformation of the strand. We model this force transport process and simplify the special Cosserat Theory to simulate inextensible hair strands. Our experiments show that the proposed approach can simulate hair dynamics robustly and efficiently such that hair simulation with user interaction can be executed in real time.
