I tried with 5.1.2 and 5.2.0-98-g5cacbab and both hang when I press Update. I copied-pasted the script from the previous e-mail.

Does it make a difference if you do things in the following order: * Add Programmable Filter * Change the output type to vtkUnstructuredGrid * Paste in script * Hit Apply now, but only after the first steps have been completed I recall that there is some funny behavior if you apply the filter and then change the output data type, so my guess is to make sure the output data type is set before applying.

So if I try to reproduce the behaviour of the clip filter, I would do: import vtk input = self.GetInputDataObject(0, 0) plane = vtk.vtkPlane() plane.SetOrigin(-4.0, 0.0, 0.0) plane.SetNormal(1.0, 0.0, 0.0) xMin = vtk.vtkClipDataSet() xMin.SetClipFunction(plane) xMin.SetInputData(input) xMin.Update() self.GetOutput().ShallowCopy(xMin.GetOutput()) I changed to the “Output Data Set Type” to vtkUnstructuredGrid. I tried but paraview stops responding ... Where am I doing something wrong ? and what am I doing wrong ? Thanks, Pierre ir.

The code inside the Programmable Filter script runs in a context in which it is aware of VTK only and not ParaView, so you cannot use paraview.simple module functions such as Clip. Instead, you would need to use a VTK-equivalent. In this case, you would use vtkClipDataSet: import vtk plane = vtk.vtkPlane() plane.SetOrigin(-4.0, 0.0, 0.0) plane.SetNormal(1.0, 1.0, 1.0) clip = vtk.vtkClipDataSet() clip.SetClipFunction(plane) clip.SetInputData(input) clip.Update() Next, to use the output of the clip filter as the output of the Programmable Filter, do the following. self.GetOutput().ShallowCopy(clip.GetOutput()) Make sure you change the Output Data Set Type to vtkUnstructuredGrid if you go this way.

Sort of like the custom filter but I want to have control over some of the properties using user input. If I understood correctly, I can get the input data with: input = self.GetInputDataObject(0, 0) then I can use this input in a filter: xMin = Clip(Input=input) xMin.ClipType = 'Plane' xMin.Crinkleclip = 1 xMin.ClipType.Origin = [-4.0, 0.0, 0.0] xMin.ClipType.Normal = [1.0, 0.0, 0.0] Now, how can I use the output of this filter as output of my programmable filter ?
