Hi everyone,
I have the handle to a facet of a 3D triangulation and would like to find the normal vector of the facet. This is how I am doing it but it looks like the normal is incorrect.

// const Facet& f is passed to this function in the function argument ...
const Point_3& p1 = f.first->vertex((f.second+1)&3)->point();
const Point_3& p2 = f.first->vertex((f.second+2)&3)->point();
const Point_3& p3 = f.first->vertex((f.second+3)&3)->point();
Vector_3 v1 = CGAL::normal(p1, p2, p3);

Am I missing something?
