void itk::QuadEdge::Splice

(

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.
