[Insight-users] itkVTKtoITKtoVTK modification

[Pieter Vos]

Hello,

I am working on the same.
I did not choose for the export/import. The reason for this is, that the
vtk part is in tcl/tk and the itk part in c++.
I work with a structured point dataset in vtk format, which is easy to
read in itk. This volume is segmented in itk with the
3DdeformableModel. It has a model/mesh as output which I have to write to
a vtk file again. But there is no itkMeshToVTKWriter (or I didn't find it
yet) so I made a procedure that write's the correct vtk file. 

I'm interessed in you're findings with the vtkImport/Export, does it work
fine? What kind of image is the toto.png?

Greetings,

Pieter
