Hi all~ I have a question for quickly get the inserted vertex's incident
vertex. To be specific, I wanna insert one weighted point to the regular
triangulation, and I just wanna focus on this just inserted vertex and try
to figure out its incident vertices in the RT (regular triangulation).
For example, before I insert vertex A, in the regular triangulation, there
are vertices B,C,D,E,F. After insertion, A is connecting to B, C, D. Now I
want to quick get vertices: B, C, D.
I have tried two method.
1st : I use vertex handle after I insert the point. Yet vertex handle do not
provide a connecting info of this new inserted point.
2nd: I need to use iterator to first get this points and use the Edge data
structure:
\\...
for(RT::Vertex_iterator vit = rt.vertices_begin(); vit!= rt.vertices_end();
++vit){
std::vector<DT::Edge> E;
dt.incident_edges(vit,std::back_inserter(E));
\\...
If there exist the method to get this problem solved?
Thanks for your kind help and guidance!
