Ejemplo n.º 2

Archivo: CGsp.cpp Proyecto: ASDen/CGsp

    typename Facet::Plane_3 operator()( Facet& f) 
	{
		typename Facet::Halfedge_handle h = f.halfedge();
        // Facet::Plane_3 is the normal vector type. We assume the
        // CGAL Kernel here and use its global functions.
        return CGAL::cross_product( h->next()->vertex()->point() - h->vertex()->point(),
									h->next()->next()->vertex()->point() - h->next()->vertex()->point() );
    }
