[vtkusers] How to find range of data in Cell Scalar Array?

[Cory Quammen]

I'm not sure if there is something in VTK that does this, but the good news
is you can use numpy to do it. See Berk's blog post series on VTK/numpy
integration starting with
https://blog.kitware.com/improved-vtk-numpy-integration/.

HTH,
