Hello:

I am studyng example examples/Mesh_2/mesh_global.cpp. The last line
prints the number of vertices.

std::cout << "Number of vertices: " << cdt.number_of_vertices() << std::endl;

I want to print instead the vertices and then the faces, so I can draw
the mesh with any mesh viewer.  Actually I am trying to create an OBJ
file.

First I print the vertices

for (CDT::Vertex_iterator vit = cdt.vertices_begin(); vit!=
cdt.vertices_end(); ++vit) {
    std::cout << "v " << (*vit) << " 0" << std::endl;
 }

Now I want to print the faces, but just the individual faces prints nothing.

for (CDT::Face_iterator fit = cdt.faces_begin(); fit!=
cdt.faces_end(); ++fit) {
    std::cout << "f " << (*fit) << std::endl;
}

Yes I am looking and trying, but no success so far.

How can I get the vertices information from the faces?

Any hint?

Regards,
