[Paraview] Clip a domain using a close surface

[Mathieu Westphal]

Hi Andrea,

This is achievable using a Programmable Filter, with the following script :

inpMain = self.GetInputDataObject( 0, 0 )

inpCut = self.GetInputDataObject( 0, 1 )

out = self.GetOutput()


cutter = vtk.vtkCutter()

cutter.SetInputDataObject( inpMain )

cutFunction = vtk.vtkImplicitPolyDataDistance()

cutFunction.SetInput( inpCut )

cutter.SetCutFunction( cutFunction )

cutter.Update()


outData = cutter.GetOutputDataObject( 0 )

out.DeepCopy(outData)

(thanks @Yves Roger for providing it here :

In case you do not know how to use the programmable filter in this
case, I have included a StateFile that demonstrate it.
Notice that we are using an "output data type : vtkPolyData".

Best regards,



Mathieu Westphal
