[Insight-users] Problem in visualizing a mesh (itkQuadEdgeMesh) extracted from a segmented object

[Martine Lefevre]

Hi, 
I extract a surface from a segmented object. the mesh is an instance of the 
QuadEdgeMesh class as I’m going to use the itkQuadEdgeMeshDiscreteGaussianCurvatureEstimator later in order to extract the curvature.
When I visualize the extracted mesh it’s simply a black image. But if I change the type of the mesh from itkQuadEdgeMesh to itk::Mesh, it works fine and I can vizualize the extracted surface.
 
So not working with a mesh of type:
typedef QuadEdgeMeshExtendedTraits < double, 3, 2, double, double, double, bool, bool > Traits;
typedef QuadEdgeMesh< double, 3, Traits > MeshType;
 
but working with: 
typedef itk::Mesh<double, 3,itk::DefaultStaticMeshTraits< double, 3, 3, double, double > > MeshType;
 
For the visualization I use the same procedure as in vtk2itk code.

 
Do you have any idea about the cause of this problem ? 
thank you  
Regards 
Martine.
