[Paraview] Cutting With Python

[Utkarsh Ayachit]

The problem with your code is that you are connecting a vtk object (the
vtkPlane) directly to a proxy (the Cut filter). To create a plane proxy
refer to Robert's link. Here's the script updated to the current CVS (
servermanager.createModule() is now directly accessible):

implicit_functions = servermanager.createModule("implicit_functions")
plane1 = implicit_functions.Plane()
plane1.Normal = [1, 0, 0]

cutfunc = servermanager.filters.Cut(Input=cube1)
cutfunc.CutFunction = plane1
cutfunc.ContourValues = [1.0,2.5]
