[Insight-users] question about save itkMesh

[Quan Xue]

Hello, ITK users:
        I meet with a question to save itkMesh object from 
Curves2DExtractor in InsightApplication into disk.
        From the mail list, I am trying to change teh itkMesh to 
vtkPolyData based on examples in vtk2itk.cxx, but I have the errors to 
tell me that the parameter should be converted.
        in vtk2itk the mesh type is defined as
typedef itk::Mesh< float, 3, itk::DefaultStaticMeshTraits<float, 3, 3, 
float, float> >floatMesh.
       but in ceExtractorConsoleBase.h
typedef itk::Point<float, 2> MeshPointDataType;
typedef itk::Mesh<MeshPointDataType, 3> MeshType
typedef itk::Mesh<MeshType::PointType, 2> ImageSpaceMeshType
      the error information is followed
