vtkPVClipDataSet not working in new PV versions

ParaView Support
1

Hello,

I have been using vtkPVClipDataSet in ParaView 5.5 but it simply does not work in PV5.7 or even PV5.10. The error that I get is the following (see the code below for testing in a programmable filter applied to a sphere source):

AttributeError: module ‘vtkmodules.all’ has no attribute 'vtkPVClipDataSet’

• How can I solve this problem ?
• It seems that this vtk tool it is no longer available. It has been deprecated?
• The VTK tool that is still working for PV 5.10 is vtkClipDataSet but this is FAR SLOWER than the vtkPVClipDataSet (especially while dealing with large datasets). There is a faster alternative to vtkClipDataSet ?

Thanks for your time !

Miguel

### CODE FOR PROGRAMMABLE FILTER ###

### BASIC CLIP    OUTPUT TYPE --> vtkUnstructuredGrid !!!!    ###



import vtk.vtkFiltersParallel

# Create survey plane:
plane = vtk.vtkPlane()
plane.SetOrigin(0,0,0)
plane.SetNormal(1, 0, 0)


# Creates a clip of the input with the survey plane:
cutter = vtk.vtkPVClipDataSet()                            # vtkPVClipDataSet is far faster than vtkClipDataSet
#cutter = vtk.vtkClipDataSet()     
cutter.SetClipFunction(plane)
cutter.SetInputData(self.GetInputDataObject(0, 0))
cutter.InsideOutOn()
cutter.Update()

self.GetOutput().ShallowCopy(cutter.GetOutput())

Hello,

I found the solution: use vtkTableBasedClipDataSet instead of vtkPVClipDataSet. Both are the fastest methods but vtkTableBasedClipDataSet is available in all Paraview versions. I left below a comparison of VTK filters clipping speed:

COMPARISON OF VTK-BASED CLIP METHODS:

vtkTableBasedClipDataSet() → It is the faster. Works in all ParaView versions
vtkClipPolyData() → 400 times slower than vtkTableBasedClipDataSet
vtkPVClipDataSet() → vtkPVClipDataSet is as fast than vtkTableBasedClipDataSet but only works in ParaView 5.5
vtkClipDataSet() → 400 times slower than vtkTableBasedClipDataSet
