Detailed Description

template<class TMesh, class TQEType>
class itk::QuadEdgeMeshEulerOperatorJoinVertexFunction< TMesh, TQEType >

Collapse a given edge by joining its dest and its org.

Collapse the argument edge e of Evaluate by joining the two vertices incident to e (i.e. its endpoints). The destination vertex of e is set aside (i.e. disconneted from its edge entry and no edge has this vertex as endpoint). Note that the vertex itself is not removed from the container (and hence there is no loss of geometrical information). On success JoinVertex returns the Id of the disconected vertex (i.e. the destination of e) and it is up to the caller to "take care" of it.

Precondition: the edge should be adjacent at least to an other edge (i.e. not be isolated at both endpoints).

Warning
JoinVertex.Evaluate( h) and JoinVertex.Evaluate( h->GetSym() ) are topologically identical. But their differ in their geometrical result, since JoinVertex removes the destination vertex of the incoming argument. A simple way to visualize this difference is to imagine a mesh constituted of squares laid out on a regular grid and for each such square an added diagonal. No imagine what happens when one operates JoinVertex on a diagonal edge of a corner square (and how it differs with feeding JoinVertex with the opposite edge).

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.
