[Insight-users] itk snap . Question

[Luis Ibanez]

Hi Ali,

Thanks for your detailed post.


It seems however that you missed
to describe what the problem is.

What exactly is what you want to fix ?

---

If you are looking for examples on how to use
VTK to visualize a segmentation produced by ITK,
then you may want to look at:

InsightApplications/Auxiliary/vtk/
     itkReadITKImage3DSegmentShowVTK.cxx

http://www.itk.org/cgi-bin/viewcvs.cgi/Auxiliary/vtk/itkReadITKImage3DSegmentShowVTK.cxx?root=InsightApplications&view=log


      Regards,


             Luis
