[Paraview] smooth a contour surface

[Hila Hiler]

Hi Tom

Lucky you are not the only one who encountered with this problem.
If you develop with VTK this
link<http://itk-insight-users.2283740.n2.nabble.com/How-to-smooth-the-segmented-surface-td7387850.html>can
help you, just follow the discussion and try to implement the
suggested
filters.

Cheers,
Hila
