Animating wet hair interacting with particle-based fluid

This paper tackles the problem of modeling the behavior of hair influenced by particle-based fluid. At each time step, the collisions of hair strands with fluid particles are detected. The dynamics of each colliding hair strand is simulated by taking into consideration the external forces exerted by fluid, such as fluid contact force, buoyant force, and the force from the surface tension of water. The hair clumping effect is simulated in a clumping process at the end of each time step. Additionally, a visually plausible hair shader is also proposed to synthesize the appearance of wet hair.
