Dear Robert, I am examining the oshhud and osgQt examples for 3 days. I also know that only depth buffer is required for osg hud example. I know. But when merge osg hud example with osg qt example it does not work. To get rid of this, I have cleared color buffer there. But in http://forum.openscenegraph.org/viewtopic.php?t=17152 , I could not get rid of this problem by using color buffer. To be clear, I have sent example little source code for these two cases.
