The biggest pitfall of history-based methods is that an error anywhere along the way can give rise to persistent tangles...This ... more Paper (PDF) Available in the Proceedings of SIGGRAPH 2003 |

Additionally, in a production environment, the simulation needs to be fast and results need to be usable "out of the box" (without extensive parameter modifications) in order to produce ... more Paper (PDF) Additional materials: [tazVideo-SCA.mov] Available in the Proceedings of the Symposium on Computer Animation 2013.
