-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi,
I make it work but using the python interface(vtkCPPythonScriptPipeline). I think for my case is easier to build pipelines with the Catalyst plugin for paraview. And anyway my paraview is already compiled with python. Thanks to all for this great feature.
