[Insight-users] Problem converting SimplexMesh back into Mesh

[Sven Olaf Lüttmann]

Dear all,
I'm having some trouble converting an itk::SimplexMesh to itk::Mesh using the 
itkSimplexMeshToTriangleMeshFilter.
I get some errors while compiling the source code and I'm I have no clue about it.

Here is a code snipped with typedefs and declarations. The first thing I do is converting my 
itk::Mesh into a SimplexMesh, after that I use it in an segmentation process and afterwards I would 
like to convert it back.

================================

  typedef itk::Mesh<double> MeshType;
  typedef itk::SimplexMesh< double > SimplexMeshType;

  typedef itk::SimplexMeshToTriangleMeshFilter< SimplexMeshType, MeshType > 
SimplexMeshToTriangleMeshFilterType;

  SimplexMeshToTriangleMeshFilterType::Pointer toMeshFilter = 
SimplexMeshToTriangleMeshFilterType::New();
  toMeshFilter->SetInput( simplexMesh );
  toMeshFilter->Update();


Here are the compiling errors I get.
================================

===============================

Has anyone an idea where the problem could be.

Thanks very much.
