Untangling Cloth

David Baraff, Andrew Witkin, Michael Kass


Deficient cloth-to-cloth collision response is the most serious shortcoming of most cloth simulation systems. Past approaches to cloth-cloth collision have used history to decide wheter nearby cloth regions have interpenetrated. The biggest pitfall of history-based methods is that an error anywhere along the way can give rise to persistent tangles...This paper describes a history-free cloth collision response algorithm based on global intersection analysis of cloth meshes at each simulation step...
