[ITK-users] Segfault in Wiki Example: QuadEdgeMeshParameterizationFilter

[Davis Vigneault]

Matt--

The changes I had were actually for the WalkInTriangulation example [1].
Did you mean to fork that instead of itkVoroniQuadEdgeMeshFilter?  In that
fork, the OrientationTest function missing from the IJ submission seems to
have been refactored as the Orientation2DFunction class [2].  (Please let
me know if I've misunderstood what you intended.)

Best, and thanks!
