Clean Cloth Inputs: Removing Character Self-Intersections With Volume Simulation

Audrey Wong, David Eberle, Theodore Kim


Simulation artists frequently work with characters that self-intersect. When these characters are sent as inputs to a cloth simulator, the results can often contain terrible artifacts that must be addressed by tediously sculpting either the input characters or the output cloth. In this talk, we apply volume simulation to character meshes and remove self-intersections before they are sent to the cloth simulator. The technique has successfully dealt with very challenging animation scenarios in a production setting, and was applied to all the characters in the short film Bao.
