Hi Petros,

I am also trying to compute the normal of a polyhedron_3 mesh at each
vertex. And I've tried using compute_vertex_normal function you mentioned
here, but I got NaN value. Here is my code:

typedef CGAL::Simple_cartesian<double>      Kernel;
typedef CGAL::Polyhedron_3<Kernel>          Polyhedron;

for (Vertex_iterator v_it = polyhedron.vertices_begin(); v_it !=
polyhedron.vertices_end(); v_it++){
Kernel::Vector_3 v_n = compute_vertex_normal<Polyhedron::Vertex,
Kernel>(Polyhedron::Vertex(v_it->point()));
}

Could you tell me which part is wrong here? Thank you very much.
