Hi Robert, The other threading models seem to work, and the osg camera example works with CullThreadPerCameraDrawThreadPerContext too. I wonder if the problem reported by Paul in the mail thread "Please test SVN of OpenSceneGraph in prep for 2.7.3 dev release" may be related to this one. I have been able to reproduce that with an older nvidia driver, but since I upgraded to 177.80 osgcamera works ok. If I read the code right, during a frame all threads enter through the _startRenderingBarrier, then the cull threads do the work while the matching draw threads are blocked, then finally the draw is done. The way I see it, one of the draw threads is still blocked waiting for the cull to happen. I'll try to add some more debug printouts, but I am still open to ideas :) -- Greets, Csaba _______________________________________________ osg-users mailing list email@example.com http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
