[Insight-users] Problem in mesh visualization with itkQuadEdgeMesh.. still waiting for a response…please help!

[Martine Lefevre]

I have posted my question yesterday but nobody answer me yet, …could you please have a look on my problem and tell me how I can resolve it. Many thanks 
Hi, 
I have extracted 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 visualize 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? 
  
attached my code 
Thank you 
Regards 
Martine.
