TLDR The authors created a realistic and efficient method to simulate hair movement by combining fluid dynamics with individual hair strand behavior.
In this paper, the authors addressed the complex problem of hair dynamics by modeling hair volume as a continuum and treating interaction dynamics as fluid dynamics. This approach proved to be strong and viable for simulating hair-hair and hair-air interactions. To maintain the individual character of hair for realistic rendering, they developed a detailed model for the stiffness and inertial dynamics of individual hair strands. The stiffness dynamics, formulated in reduced coordinates, was numerically stable and fast. They successfully unified the continuum interaction dynamics with the individual hair's stiffness dynamics.
