Hi Matthieu! I investigated the same question recently, here is what I found so far.
In Catalyst/CoProcessing the python script is used to create a vtk pipeline --------- vtkNew<vtkCPPythonScriptPipeline> pipeline; pipeline->Initialize(scriptPath) --------- This pipeline will be passed to vtk processor that will do the CoPorcessing by executing the pipeline ------ vtkCPProcessor* Processor = vtkCPProcessor::New(); Processor->Initialize(); Processor->AddPipeline(pipeline.GetPointer()); Processor->CcProcess(...) ------ checking the souce code of VtkCPProcessor ( https://gitlab.kitware.com/paraview/paraview/blob/master/CoProcessing/Catalyst/vtkCPProcessor.h ) ---- /// Add in a pipeline that is externally configured. Returns 1 if /// successful and 0 otherwise. virtual int AddPipeline ( vtkCPPipeline * pipeline ); ------- a vtkCPProcessor object can add a pipeline of any class extending the vtkCPPipeline (which is a an abstract class) Beside of the official python implementation ( https://gitlab.kitware.com/paraview/paraview/blob/master/CoProcessing/PythonCatalyst/vtkCPPythonScriptPipeline.h ) I am not aware of any other implementation. Otherwise, you can to implement your own implementation (which looks very time consuming ...). http://www.vtk.org/Wiki/VTK/Tutorials/New_Pipeline Hope this helps. I'll be interested if some one is aware of any c++ implementation of the pipeline.
