[Insight-users] [Segfault] itk::NormalQuadEdgeMeshFilter and itk::WarpMeshFilter

[Oscar Esteban]

Hi all,

I'm trying to compute the Normals of a QuadEdgeMesh after warping it with
itk::WarpMeshFilter and a displacement field.

I save to vtk files the result and the points seem to be correctly
displaced, but when computing the normals, I get a segmentation fault in
line 302 of itkQuadEdge.h.

I think that the output Mesh after the WarpMeshFilter lacks of some
properties needed by the normals filter.

In order to solve this, I could copy this properties from the input mesh to
the output. This are my questions:
- What is missing after the WarpMeshFilter?
- How to safely clone (deep-copy) a QuadEdgeMesh? (I have this problem in
some other parts of my code).

Thank you so much in advance.

Best,
Oscar Esteban
