[Insight-users] Smart pointer destruction

[Luis Ibanez]

Hi Diego,

Please look at the examples of code in the directory:


      InsightApplications/
             Auxiliary/vtk/
               itkReadITKImage3DSegmentShowVTK.cxx
               itkReadITKImageSegmentShowVTK.cxx
               itkReadITKImageShowSplineVTK.cxx
               itkReadITKImageShowVTK.cxx



Regards,

    Luis
