Jana,

itk::QuadEdgeMesh is an oriented mesh data structure, it ensures the consistency of normals.
itk::NormalQuadEdgeMeshFilter only computes the normal for each face and each vertex, and thanks to the data structure all normal are thus consistent.

Dear users, 

I read itkNormalQuadEdgesMeshFilter code and it does not seam to me /at the first glance/ that it insures consistent orientation across polygon neighbors.

I am new in ITK, does it deals with this problem  ( as for example vtkPolyDataNormals does ) ?

Thank you very much

Jana
