I have a verson of vtkOBBTree with IntersectWithLine and
IntersectWithOBBTree. You are welcome to it at:

ftp://duke.bwh.harvard.edu/pub/people/peverett/vtkOBBTree.h
ftp://duke.bwh.harvard.edu/pub/people/peverett/vtkOBBTree.cxx
ftp://duke.bwh.harvard.edu/pub/people/peverett/vtkCellTriMacro.h

This also fixes some bugs in the OBB computation.

Enjoy,
Peter C. Everett
