Selective and dynamic cloth fold smoothing with collision resolution

We present techniques to selectively and dynamically detect and smooth folds in a cloth mesh after simulation. This gives artists the controls to emphasize or de-emphasize certain folds, cleanup simulation errors that can cause crumpled cloth, and resolve cloth-body interpenetrations that can happen during smoothing. These techniques are simple and fast, and help the artist to direct, cleanup, and enrich the look of simulated cloth.
