[vtkusers] Render results differ with Paraview

[Slaughter, Andrew E]

I am writing a VTK python script (VTK7.0.0 on OSX) to read and render an
ExodusII file. I am getting results that differ quite a bit from Paraview
(4.3.1), as shown in the attached images.

My python script (also attached) produces a result that is not nearly as
smooth as Paraview.  I am likely using an incorrect filter or missing some
setting and would appreciate if someone could assist me in improving my
script.

Thanks,

Andrew
