Re: [osg-users] MultiThreaded Culling
Yep, got it thanks. It just seemed weird since I'm not a multithreader understander, how you could start the graphics thread before getting to the main frame loop, but at the same time be sure that the culling happens before the draw of the graphics thread. But I guess it just works. Thanks.

My guess would be that it happens in the same thread as the event and update traversals. But one sure way to find out would be to set a breakpoint in one of the CullVisitor apply methods and look at the call stack and thread ID. -Paul ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] MultiThreaded Culling
Hi Dan, When you use DrawThreadPerContext the viewers main frame loop does the culling for the viewers cameras. Robert.
