Real-time hair mesh simulation

We present a robust real-time hair simulation method using hair meshes. Leveraging existing simulation models for sheet-based cloth, we introduce a volumetric force model for incorporating hair interactions inside the hair mesh volume. We also introduce a position correction method that minimizes the local deformation of the hair mesh due to collision handling. We demonstrate the robustness of our hair simulation method using large time steps with fast motion, and we show that our method can recover the initial hair shape even when the hair mesh goes through substantial deformation.
