We announce the release of a new proximity query package called SWIFT.
SWIFT is a C++ library for collision detection, exact and approximate
distance computation, and contact determination of three-dimensional
polyhedral objects undergoing rigid motion.

SWIFT combines multi-resolution representations with Voronoi based
walking (first proposed by Lin and Canny).  Some preliminary results
indicate that it is faster than I-COLLIDE and V-CLIP, and more robust
than I-COLLIDE.  It has been successfully applied to virtual prototyping,
dynamic simulation, path planning and other applications. It is free
for non-commercial use.
