[Insight-users] how to draw an itk mesh as a vtk object?

[Luis Ibanez]

Hi Gwenael,


(Option A):  convert the itk::Mesh to an vtkUnstructuredGrid
    using the code in

        InsightApplications/Auxiliary/vtk/vtk2itk.cxx


(Option B): use itkImageToVTKimage for converting your
    itk binary image into a VTK image Data. Then use the
    VTK filter vtkContourFilter for extracting a VTK
    surface.


--------


(B) is a much better way to go.




Note that you may want to apply the anti-alias filter

before converting the ITK image to vtkImageData. This will produce
smoother surfaces.



Regards,


    Luis
