[ITK-users] Segfault in Wiki Example: QuadEdgeMeshParameterizationFilter

[Matt McCormick]

Hi Davis, Arnaud,

I have forked the repositories to:

  https://github.com/InsightSoftwareConsortium/itkVoronoiQuadEdgeMeshFilter
  https://github.com/InsightSoftwareConsortium/ITKPointInCircle

if you want to develop there.

HTH,
Matt
