Detailed Description

This class circulates through all one-ring neighbors of a vertex. It also acts as a container-concept for C++11 range-based for loops.

The follow code shows how to use VertexAroundVertexCirculator:

SurfaceMesh::VertexAroundVertexCirculator cir(mesh, v);
SurfaceMesh::VertexAroundVertexCirculator end = cir;
do {
    SurfaceMesh::Vertex v = *cir;
    // do something with v
    ++cir;
} while (cir != end);
