Detailed Description

template<class MeshT>
class pcl::geometry::FaceAroundVertexCirculator< MeshT >

Circulates counter-clockwise around a vertex and returns an index to the face of the outgoing half-edge (the target).

The best way to declare the circulator is to use the method pcl::geometry::MeshBase::getFaceAroundVertexCirculator ().

Template Parameters
MeshTMesh to which this circulator belongs to.
Note
The circulator can't be used to change the connectivity in the mesh (only const circulators are valid).

template<class MeshT >
HalfEdgeIndex pcl::geometry::FaceAroundVertexCirculator< MeshT >::getCurrentHalfEdgeIndex ( ) const
inline

Get the half-edge that is currently stored in the circulator.

Check if the circulator is valid.

Warning
Does NOT check if the stored mesh pointer is valid. You have to ensure this yourself when constructing the circulator.
