Hi Tim, Have you looked at the python programmable source? With the python programmable source you can specify python code to run on the server side. You won't be able to use paraview python api though. Instead of
XDMFReader(FileName=...) it would look like: reader = vtkXDMFReader() reader.SetFileName(...) reader.Update() data = reader.GetOutput() You can find examples of the python programmable source: http://www.paraview.org/Wiki/Python_Programmable_Filter#Generating_Data_.28Programmable_Source.29 http://www.paraview.org/Wiki/Here_are_some_more_examples_of_simple_ParaView_3_python_filters .
