C2A: CCD library for general polygon soup models

We announce the release of a free, real-time continuous collision detection library for rigid, polygon-soup models.

http://graphics.ewha.ac.kr/C2A/

The performance of C2A is superior or comparable to that of a specialized algorithm for a 2-manifold surface model (e.g. http://graphics.ewha.ac.kr/FAST).

Any feedback or bug-report will be appreciated.

Thank you.

Conservative advancement is basically one-sided root finding. It has trouble with fast rotating objects that are close together. Advancement can be arbitrarily small. A typical example is a domino standing vertically on a plane. Imagine that the domino is knocked over. There is already a very close point at the bottom (held up by the solver) and the domino is rotating downward quickly.
