Free Collision Detection System Released

Collide Research Group has released SWIFT++, a free collision detection package. Swift++, which stands for "Speedy Walking via Improved Feature Testing" (for Non-Convex Objects), is capable of detecting intersection, performing tolerance verification, computing approximate and exact distance, or determining the contacts between pairs of objects in a scene composed of general rigid polyhedral models. SWIFT++ combines convex surface decomposition with a convex bounding volume hierarchy and Voronoi based walking. This reworking of the original SWIFT system, released from the University of North Carolina, still uses the original core as the main bounding volume subroutine. SWIFT++ has performance improvements over the original, with a powerful and simple API and improved proximity query capabilities.
