Hi,

Is there a way to insert points into a triangulation using the range
insert function while assigning ids to each point (using
Triangulation_vertex_base_with_id_2)? Am I able able to use my point
types?

Currently, I'm iterating through the points, inserting, and then
assigning an id.

typedef CGAL::Triangulation_euclidean_traits_xy_3<K> TriangulationTraits;
typedef CGAL::Triangulation_vertex_base_with_id_2<TriangulationTraits>
TriangulationVertexBase;
typedef CGAL::Triangulation_data_structure_2<TriangulationVertexBase>
TriangulationDataStructure;
typedef 
CGAL::Delaunay_triangulation_2<TriangulationTraits,TriangulationDataStructure>
Trianglulation;

int id = 0;
vector< Point_3 > points;
// ... fill points
for (vector< Point >::const_iterator p = points.begin(); p !=
points.end(); ++p, ++id ) {
     Trianglulation::Vertex_handle v = triangulation.push_back(*p);
     v->id() = id;
 }

But, I thought, using the range iterator is more efficient:

vector< Point_3 > points;
// ... fill points
triangulation.insert(points.begin(), points.end());  // How do I
assign an id to each vertex here?

Thanks,
Sam
