Hello, is it possible to extend the example at http://www.vtk.org/Wiki/VTK/MultiPass_Rendering_With_IceT for parallel rendering including transparent objects?
I have tried to modify the above example by first setting actor->GetProperty()->SetOpacity(0.3); after creation of the actor, and, second, adding vtkSmartPointer<vtkTranslucentPass> translucent = vtkSmartPointer<vtkTranslucentPass>::New(); passes->AddItem(translucent); after the original line "passes->AddItem(opaque);". The result is for example, when running with 3 MPI processes: The sphere segments in the partial Renderers of process 1 and 2 are transparent (but show some artefacts). The composite Renderer of process 0 doesn't show any sphere, just the black background! When the opacity is set to 1, the sphere segments are composited in three colors on process 0 as expected. What is required to correctly perform parallel rendering including transparency? (I am using ParaView-v5.0.1, compiled from source on Ubuntu 15.04) Thank you Kai
