ABSTRACT
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 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 on the short film, Bao.

Faking dynamics of cloth animation for animated films
AMDO'10: Proceedings of the 6th international conference on Articulated motion and deformable objectsIn this paper we argue for the concept of fake dynamics to allow animators to interactively create visually pleasing animations of cloth models while keeping him/her in full control of the animation process. Existing animation and simulation techniques ...
Data driven cloth animation
SIGGRAPH '07: ACM SIGGRAPH 2007 sketchesWe present a new method for cloth animation based on data driven synthesis. In contrast to approaches that focus on physical simulation, we animate cloth by manipulating short sequences of existing cloth animation. While our source of data is cloth ...
