[Paraview] vtkClipDataSet in a programmable filter

[Cory Quammen]

This works for me in 5.4.1:

import vtk

plane = vtk.vtkPlane()
plane.SetOrigin(0, 0, 0)
plane.SetNormal(0, 1, 0)

clip = vtk.vtkClipDataSet()
clip.SetClipFunction(plane)
clip.SetInputData(self.GetInput())
clip.Update()

self.GetOutput().DeepCopy(clip.GetOutput())

Make sure you set the "Output Data Set Type" to "vtkUnstructuredGrid"
before you first hit Apply. I believe there is a bug that does not let
you change the output data set type after you first click Apply.

HTH,
Cory
