That sounds very good. Is it the
http://www.cs.unc.edu/~geom/collide/packages.html#VCOLLIDE package? As far
as I can see this  package build on top of RAPID which is an OBBTree based
collision detection algorithm. Are you using the OBBTree allready
implemented in VTK?

I am not sure about redistribution. If you make an independent
implementation based on a published article, there should be no problems...?
If you wrap the UNC code I believe there can be some problems.

Thanks for the feedback
