<div>Hi,</div><div><br></div><div>My first implementation is on Github:</div><div><br></div><div><a href="https://github.com/bilke/pv_opensg_plugin">https://github.com/bilke/pv_opensg_plugin</a></div><div><br></div><div>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.</div><div><br></div><div>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.</div><div><br></div><div>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:</div><div><br></div><div><div>Debug: In /Users/lars/ent/ParaView-Plugins/pv_opensg_plugin/vtkOpenSGExporter.cxx, line 50</div><div>vtkOpenSGExporter (0x7ff3bc0ef590): OpenSG converter initing</div><div><br></div><div><br></div><div>Debug: In /Users/lars/ent/kitware/ParaView-3.8.1/VTK/Common/vtkObject.cxx, line 845</div><div>vtkOpenSGExporter (0x7ff3bc0ef590): Registered by vtkClientServerInterpreter (0x7ff3b9cccfd0), ReferenceCount = 2</div><div><br></div><div><br></div><div>Debug: In /Users/lars/ent/kitware/ParaView-3.8.1/VTK/Common/vtkObject.cxx, line 870</div><div>vtkOpenSGExporter (0x7ff3bc0ef590): UnRegistered by NULL, ReferenceCount = 1</div><div><br></div><div><br></div><div>Debug: In /Users/lars/ent/kitware/ParaView-3.8.1/VTK/Common/vtkObject.cxx, line 845</div><div>vtkOpenSGExporter (0x7ff3bc0ef590): Registered by vtkClientServerInterpreter (0x7ff3b9cccfd0), ReferenceCount = 2</div><div><br></div><div><br></div><div>Debug: In /Users/lars/ent/kitware/ParaView-3.8.1/VTK/Common/vtkObject.cxx, line 865</div><div>vtkOpenSGExporter (0x7ff3bc0ef590): UnRegistered by vtkClientServerInterpreter (0x7ff3b9cccfd0), ReferenceCount = 1</div><div><br></div><div><br></div><div>Debug: In /Users/lars/ent/ParaView-Plugins/pv_opensg_plugin/vtkOpenSGExporter.h, line 47</div><div>vtkOpenSGExporter (0x7ff3bc0ef590): vtkOpenSGExporter (0x7ff3bc0ef590): setting FileName to /Users/lars/Desktop/test.osb</div><div><br></div><div><br></div><div>Debug: In /Users/lars/ent/kitware/ParaView-3.8.1/VTK/Common/vtkObject.cxx, line 865</div><div>vtkOpenSGExporter (0x7ff3bc0ef590): UnRegistered by vtkClientServerInterpreter (0x7ff3b9cccfd0), ReferenceCount = 0</div><div><br></div><div><br></div><div>Debug: In /Users/lars/ent/ParaView-Plugins/pv_opensg_plugin/vtkOpenSGExporter.cxx, line 61</div><div>vtkOpenSGExporter (0x7ff3bc0ef590): OpenSG converter exiting</div><div><br></div><div><br></div><div>Debug: In /Users/lars/ent/kitware/ParaView-3.8.1/VTK/Rendering/vtkExporter.cxx, line 20</div><div>vtkExporter (0x7ff3bc0ef590): vtkExporter (0x7ff3bc0ef590): setting RenderWindow to 0</div><div><br></div><div><br></div><div>Debug: In /Users/lars/ent/kitware/ParaView-3.8.1/VTK/Common/vtkObject.cxx, line 153</div><div>vtkObject (0x7ff3bc0ef590): Destructing!</div><div><br></div><div><br></div></div><div>Thanks for your help!</div><div>Lars.</div><div><br></div>
