Cory, Thanks for your quick answer and clarifying the context.
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. Hope that helps, Cory On Wed, Jan 11, 2017 at 8:49 AM, Crepier, Pierre <p.crep...@marin.nl<mailto:p.crep...@marin.nl>> wrote: Hi everyone, I am trying to use the programmable filter to combine multiple filters. 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 ?
