Self* itk::QuadEdge::GetDnext ( )

Returns next edge with same right face and same Destination. The first edge encountered when moving counter-clockwise from e (see "Accessing adjacent edges").

const Self* itk::QuadEdge::GetDnext ( ) const
Self* itk::QuadEdge::GetDprev ( )

Returns the previous edge with same Right face and same Destination. The first edge encountered when moving clockwise from e around e->Dest. (see "Accessing adjacent edges").

void itk::QuadEdge::Splice ( Self b)
inline

Basic quad-edge topological method.

This method describes all possible topological operations on an edge.

It is its own inverse. It works in two ways:

  1. If this->GetOrg() != b->GetOrg(), it slice a face in two.
  2. If this->GetOrg() == b->GetOrg(), it unifies two faces.
Warning
This class only handles of the connectivity and is not aware of the geometry that lies at the GeometricalQuadEdge level. It is strongly discouraged to use this method. Instead you should use itk::QuadEdgeMesh::Splice it's geometry aware version.
