Hi

I mean the two polyhedrons touch(share a common point, edge, or face).

It seems when I use the function, it will output the two polyhedrons intersect in this case.

But in my problem, this case requires to be considered no intersection.

Can you give me some hints about how to check this case?

Thanks for your help.

Vanessa

Hi all

I'm trying to do the intersection test for two 3D polyhedrons using the
function"CGAL::intersection_Polyhedron_3_Polyhedron_3(Poly1, Poly2,
  std::back_inserter(polylines));".

It performs well.But when one polyhedron is in contact to the other, the
output (size of polylines) shows 1 instead of 0. Is there any method to
check the case that two polyhedrons are in contact?

What do you mean by in contact?
IIRC, note that this function is will not report intersection points.

Sebastien.

Many thanks
Vanessa
