    A Robust Volume Conserving Method for Character-Water Interaction
    (ACM, 2019) Lee, Minjae; Hyde, David; Li, Kevin; Fedkiw, Ronald; Batty, Christopher and Huang, Jin
    We propose a novel volume conserving framework for character- water interaction, using a novel volume-of-fluid solver on a skinned tetrahedral mesh, enabling the high degree of the spatial adaptiv- ity in order to capture thin films and hair-water interactions. For efficiency, the bulk of the fluid volume is simulated with a stan- dard Eulerian solver which is two way coupled to our skinned ar- bitrary Lagrangian-Eulerian mesh using a fast, robust, and straight- forward to implement partitioned approach. This allows for a spe- cialized and efficient treatment of the volume-of-fluid solver, since it is only required in a subset of the domain. The combination of conservation of fluid volume and a kinematically deforming skinned mesh allows us to robustly implement interesting effects such as adhesion, and anisotropic porosity.We illustrate the efficacy of our method by simulating various water effects with solid objects and animated characters.
