[Insight-users] Mesh Types: Error in visualizing

[Luis Ibanez]

Hi Uday,

If you want to visualize the surface of the segmented region,
it is not a good idea to use the itkBinaryMask3DMeshSource.

Instead you should convert your ITK image resulting from the
segmentation into a VTK image and then apply the vtkContourFilter
on the resulting vtkImageData object. Then take the vtkPolyData
resulting from the Contour filter and connect it to a standard
VTK visualization pipeline.


For your convenience we just added an example illustrating
how to do this. You will find this new example in

   InsightApplications/Auxiliary/vtk
               itkReadITKImageSegmentShowVTK.cxx

Note that although the example is illustrated for a 2D image,
you can adapt it to 3D with minimal modifications.


    Regards,


       Luis
