Hi,

 

Now I am using the Triangulations Algorithom,I have a problem that how can I get the sequence number of the vertices after inserted ?

 

I use this method but it is inefficiency :

 

Triangulation tr;

 

size_type get_vertex_no(Vertex_handle vh) {

Vertex_iterator vit = tr.vertices_begin();

size_type no = 0;

for (; vit != tr.vertices_end() ; ++vit) {

if (vh == vit)

break;

no ++;

}

return no;

}
