hi all,
    i work with triangulated surfaces some times containing as much as 100000 
triangles. Problem with the ray tracing to find the intersection point is it 
has to loop through all the triangles to find the closest triangle. is there a 
way to eliminate the triangles that are faroff from the potential point of 
contact and speed up the process.
