[Insight-users] Help in understanding how to connect ITK and VTK

[Gaetan Lehmann]

Kalle,

I'm not sure what is the best solution in your case, however, if you want  
to use itk classes directly from python, you should use WrapITK.
WrapITK will let you:
- choose the types you want to build
- easily select types in your python program
- easily connect itk to vtk - it's exactely the same interface than in c++
- easily extend itk with some custom classes - that's the case of the  
itk-vtk glue code
- ...

WrapITK is available at

   http://voxel.jouy.inra.fr/darcs/contrib-itk/WrapITK/WrapITK.tar.gz

or directly with darcs (http://www.darcs.net)

Are you working on BioImageXD ?
