Hi Dave, We have been trying to extend DMTCP for checkpointing 3D graphics but it’s completely experimental right now. We have managed to checkpoint blender for some limited use cases.
I am not sure if VNC, by default, supports running applications that use OpenGL, so that might not work even without DMTCP. Some commercial versions claim to support it but I haven’t been able to verify that. Could you give a little more details about your use-case? What command line options you use to start blender? What version of OpenGL library are you using? I can try that at our end and get back to you. We can also try to extend the set of graphics objects that DMTCP supports based on your requirements.
