Hello, A Regular_triangulation_3 is derived from Triangulation_3 where you can find he function: https://doc.cgal.org/latest/Triangulation_3/classCGAL_1_1Triangulation__3.html#aa9814b11ee0a6e024fd3cee4cff066c3 best, andreas

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! -- Sent from: http://cgal-discuss.949826.n4.nabble.com/ -- Andreas Fabri, PhD Chief Officer, GeometryFactory Editor, The CGAL Project phone: +33.492.954.912 skype: andreas.fabri |
