Hi, My first implementation is on Github:
https://github.com/bilke/pv_opensg_plugin at Utkarsh: I am sorry my last mail: I used the development install of ParaView and the crashes came from a binary difference I think. Now I compiled ParaView from source and got rid of crashes. The problem is that it never executes the WriteData()-method from my exporter. I also noticed that this method is not executed because the vtkSMRenderViewExporterProxy::Write()-method is also not executed. I assume that my exporter class itself is fine but the server manager configuration is missing something. I turned on the debug output of my exporter (you see that the RenderWindow is never set and also the Write()-method is never executed). This is the output when trying to export as OpenSG: Debug: In /Users/lars/ent/ParaView-Plugins/pv_opensg_plugin/vtkOpenSGExporter.cxx, line 50 vtkOpenSGExporter (0x7ff3bc0ef590): OpenSG converter initing Debug: In /Users/lars/ent/kitware/ParaView-3.8.1/VTK/Common/vtkObject.cxx, line 845 vtkOpenSGExporter (0x7ff3bc0ef590): Registered by vtkClientServerInterpreter (0x7ff3b9cccfd0), ReferenceCount = 2 Debug: In /Users/lars/ent/kitware/ParaView-3.8.1/VTK/Common/vtkObject.cxx, line 870 vtkOpenSGExporter (0x7ff3bc0ef590): UnRegistered by NULL, ReferenceCount = 1 Debug: In /Users/lars/ent/kitware/ParaView-3.8.1/VTK/Common/vtkObject.cxx, line 845 vtkOpenSGExporter (0x7ff3bc0ef590): Registered by vtkClientServerInterpreter (0x7ff3b9cccfd0), ReferenceCount = 2 Debug: In /Users/lars/ent/kitware/ParaView-3.8.1/VTK/Common/vtkObject.cxx, line 865 vtkOpenSGExporter (0x7ff3bc0ef590): UnRegistered by vtkClientServerInterpreter (0x7ff3b9cccfd0), ReferenceCount = 1 Debug: In /Users/lars/ent/ParaView-Plugins/pv_opensg_plugin/vtkOpenSGExporter.h, line 47 vtkOpenSGExporter (0x7ff3bc0ef590): vtkOpenSGExporter (0x7ff3bc0ef590): setting FileName to /Users/lars/Desktop/test.osb Debug: In /Users/lars/ent/kitware/ParaView-3.8.1/VTK/Common/vtkObject.cxx, line 865 vtkOpenSGExporter (0x7ff3bc0ef590): UnRegistered by vtkClientServerInterpreter (0x7ff3b9cccfd0), ReferenceCount = 0 Debug: In /Users/lars/ent/ParaView-Plugins/pv_opensg_plugin/vtkOpenSGExporter.cxx, line 61 vtkOpenSGExporter (0x7ff3bc0ef590): OpenSG converter exiting Debug: In /Users/lars/ent/kitware/ParaView-3.8.1/VTK/Rendering/vtkExporter.cxx, line 20 vtkExporter (0x7ff3bc0ef590): vtkExporter (0x7ff3bc0ef590): setting RenderWindow to 0 Debug: In /Users/lars/ent/kitware/ParaView-3.8.1/VTK/Common/vtkObject.cxx, line 153 vtkObject (0x7ff3bc0ef590): Destructing!
