thanks, I think I got it. If I'm not mistaken, the handle is just a pointer
to the vertex, which represents the mathematical concept of a vertex. Then
you call the appropriate function to get numerical representation of the
data like point() for position in space, index() for the position in the
data structure.
Am I Correct ?

At that point, iter->vertex(i) is a Vertex_handle, for example:
Vertex_handle vh = iter->vertex(0);
and you can access the Vertex like that:
Vertex& v = *vh;
if you want to access the Point_3:
vh->point()
