Hello,
I am trying to write a Triangle_3_Triangle_3 _intersection function based on the Triangle_3_Segment_3_intersection.h code (URL: https://scm.gforge.inria.fr/svn/cgal/trunk/AABB_tree/include/CGAL/AABB_intersections/Triangle_3_segment_3_intersection.h ). I just started it so it is far from complete. I understand that this code is not included in any of the releases yet (and is maybe not complete?), but I was hoping that someone could help me out with the errors I am getting (or maybe just say the code is not ready for use yet? :) ). Below is the code that I am trying to use and the error that I am getting.
Thanks,
Matt
