All circulators provide the operations listed in
OpenMesh::Concepts::CirculatorT, which are basically the same as the
CirculatorT<Mesh>, which are basically the same as the
iterator funtions.
Furthermore, circulators provide \c operator \c bool(), which returns
true, as long as the circulator hasn't reached the end of the
Example: The following code enumerates the 1-ring of each vertex:
%OpenMesh provides the following functions (defined in OpenMesh::PolyConnectivity)
to get circulators around a specified center item:
Note that for every circulator there also exists a constant version.
To make use of these constant circulators just add the prefix<br />
"Const" to the type specifier and add the prefix "c" to the function used to request
the circulator of an item. Example:<br/>
<code>ConstVertexVertexIter cvvit = mesh.cvv_iter(some_vertex_handle);</code>
The following code example now shows how to enumerate the 1-ring of each vertex:
