A novel algorithm of collision handling for fluid based hair model
Yong Tang · Journal of Yanshan University · 2010
In order to get more detail behaviors of hairs, each hair strand is simulated using mass-spring models as opposed to clumped modles. For sake of efficiency, a method that combines Lagrangian techniques and Eulerian techniques is proposed to handle self-collision of hairs. The approach divided the hair space into many cells, and the hair density and velocity of each cell are calculated in the center, then Lagrangian techniques is applied to every particles, thus, the velocity and position of each particle are updated within one time step. The experiments demonstrate that this method can simulate dynamic hairs efficiently.
