Take a look at the following sites for code and papers
on Collision detection.
I-Collide at : http://www.cs.unc.edu/~geom/I_COLLIDE.html
Rapid at: http://www.cs.unc.edu/~geom/OBB/OBBT.html
While work working for my last company we adapted RAPID as an
exercise, to work with Performer for Geometry to Geometry
collision detection.
Hope this maybe of use.
