Hello, A word about the context: I am working on a library that uses Catalyst to do Live visualization with ParaView. In this library, I just create a proxy to a PVTrivialProducer and then set its output to send the data (vtkUnstructuredGrid) to ParaView. This part is working very well.
I built the 5.0.0 version of ParaView on our data server with the OpenGL2 backend enabled, but when I built the 5.0.0 version of ParaView on my client with OS X (I needed the developement headers), I noticed that I forgot to add the option to enable the new OpenGL backend: -DVTK_RENDERING_BACKEND=OpenGL2. So I ended up having version 1.4 for OpenGL in this version. When I tried to use our application with Catalyst, everything worked fine, until I wanted to visualize the data extract from the proxy in the ParaView interface. ParaView then crashed with the following error: " ERROR: In /tmp/ParaView-v5.0.0-source/ParaViewCore/ServerImplementation/Core/vtkSIProxy.cxx, line 310 vtkSISourceProxy (0x4aefb50): Failed to create vtkPointGaussianRepresentation. Aborting for debugging purposes. Aborted " Looking at the proxy definition in ParaViewCore/ServerManager/SMApplication/Resources/, I see that there is a proxy for vtkPointGaussianRepresentation in proxies_opengl2.xml, but not in proxies_opengl1.xml. Am I getting an expected behavior here due to the option I forgot ? Note that I also have the standard pre-packaged version of ParaView (with the OpenGL2 backend and OpenGL v4.1) installed on OS X and I don't get the previous issue and everything is ok. In summary and with version 5.0.0 for everything: ParaView (No OpenGL2) -> pvserver (OpenGL2) : causes a crash ParaView (OpenGL2) -> pvserver (OpenGL2) : is OK What do you think about checking the version of the OpenGL backend when connecting to a pv*server and see if they match ? And possibly display a message similar to the one displayed, when ParaView connects to a different version of pvserver (e.g. when a client in 4.4.0 to a server in 5.0.0) Best regards, Alexandre Ancel -- Alexandre Ancel Docteur, Ingénieur de recherche / Phd, Research Engineer Cemosis <http://www.cemosis.fr> - [email protected] Tel: +33 (0)3 68 8*5 02 06* IRMA - 7, rue René Descartes 67 000 Strasbourg, France
