[Insight-developers] converting a byu-based vtkPolyData to QuadEdgeMesh: SetCell() not successful...

[Michel Audette]

Hi Alex,

just wondering, but it seems that QuadEdgeMesh::AddFace can call
AddFaceWithSecurePointList(), which in turn can call AddFace().

Does that make sense? Is it possible that leads to the wrong number of
faces?

Best wishes,

Michel
