Hm, not sure you understand how this works (or I'm not understanding your question). First, draw your scene, everything but the Sun and glare. Second, draw the Sun with occlusion query enabled. Third, use the result of that query to determine whether or not to draw the glare (or how much of the glare to draw). Finally, as an optimization, use the occlusion result from the previous frame so you don't cause a rendering pipe flush. You do not need to "occlusion query the whole database". -Paul _______________________________________________ osg-users mailing list [email protected] http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/
