 Check out "proxima", from Purdue, which is a C++ library for 3D
collision detection for arbitrary polyhedra.  It's a nice system;
the algorithms are sophisticated, but the code is of modest size.

Graphics Gems IV, pages 83-109, includes source in C.
SOLID: "a library for collision detection of three-dimensional
objects undergoing rigid motion and deformation. SOLID is designed to
be used in interactive 3D graphics applications, and is especially
suited for collision detection of objects and worlds described in VRML.
Written in standard C++, compiles under GNU g++ version 2.8.1 and
Visual C++ 5.0."  See:        http://www.win.tue.nl/cs/tt/gino/solid/
