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
MeshT Mesh 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).

Member Function Documentation

getCurrentHalfEdgeIndex()

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

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

References pcl::geometry::FaceAroundVertexCirculator< MeshT >::idx_outgoing_half_edge_.

getTargetIndex()

template<class MeshT >
FaceIndex pcl::geometry::FaceAroundVertexCirculator< MeshT >::getTargetIndex ( ) const
inline

Get the index to the target face.

isValid()

template<class MeshT >
bool pcl::geometry::FaceAroundVertexCirculator< MeshT >::isValid ( ) const
inline
