CGAL users discussion list

Hi, all:

I want to compute the interactions between lots of 3D polyhedrons using CGAL. It becomes low efficient when facing hundreds of objects. So I tried to parallel the code with the simple multi-thread OpenMP. But the segmentation fault always occur. Here is the code of the simple case:

#pragma omp_parallel_for

 for(int i=0; i<Object.size(); i++)

{

      CGSurfaceMesh smesh_insect;

      bool valid_intersect = CGAL::Polygon_mesh_processing::corefine_and_compute_intersection(Object[i], TargertObject, smesh_insect);

}

I don't know how to figure that out. And do you have any suggestions on improving efficiency when handling hundreds of 3D intersections using CGAL?

Thanks a lot!

Best wishes,

Daye
