Performer has no real mechanism to perform volume to volume collision
detection. However, our group has successfully integrated a public library
implementing this functionality. You'll find more on the subject at
this address: http://www.cs.unc.edu/~geom/OBB/OBBT.html
We used the RAPID library with the ISECT process to perform collision detection
on various objects comprising the visual database of the International Space
Station. Results are impressive... These people at UNC did a very good job.
