Nice one. The only light I can shed on this is that there has been issues with the various threading models that OSG claims to support. Recent conversation (today's correspondance is a good example) indicates that all is not great in multithreaded/multicamera world! As far as we are concerned for the moment I'm assuming that we will have a singlethreaded universe. This may well change, however, should we decide to be clever with reflections and set up a seperate thread for handling the texture generation of this. However, that's a little way down the road :-) I note that I don't think this used to happen under OSG1.2 - although I may be wrong. Neil.

Hi OSGers, I'm a bit of a newbie to OSG, but I've been developing an application based on the osgviewerMFC example in OSG2.0 (built using VS2005). The problem that I discovered with my application (and the unmodified example) is that once I have loaded in a model (e.g. cow.osg or glider.osg) the program does not terminate properly. It seems to close, but remains as a process consuming CPU resource until I manually terminate it using task manager. As "a shot in the dark" I guessed the problem might be something to do with threads, so I added the line: mViewer->setThreadingModel(osgViewer::Viewer::SingleThreaded); just before the call to: mViewer->realize() This seemed to cure the problem, so just thought someone might find this info useful. Why does this problem occur? What have I lost by setting single threaded mode? And.. has it been fixed in later versions?
