Instead of a circulator, there is a function incident_cells()
http://doc.cgal.org/latest/Triangulation_3/classCGAL_1_1Triangulation__3.html#a4aaef5614eda5f25fe0c7f01174e40d8
that writes into a container, e.g

std::vector<Cell_handle> neighbors;
t.incident_cells(v, std::back_inserter(neighbors));

best,

andreas

Dear all,
I want to visit all cells incident to a given vertex in 3D
triangulation data structure. In 2D Triangulation Data Structure,
there is vertex_circulator to implement the function. But in
3D triangulation data structure, there is no vertex_circulator. If
there is another function to visit all cells incident to a given
vertex in 3D triangulation data structure?

Thanks.

Tianyun
