Hi, When I was playing around with the osgviewerGlut example, I realized that there was no actual interaction between the what I was drawing with openGL and with osg. It seems like whatever is drawn later occludes what is already there. When viewer->frame() is called, even what should be clear background blocks out already drawn objects.
I've tried messing around with camera settings (and broken my application in many interesting ways), but I can't figure out how to avoid losing all of my already rendered stuff when I call viewer->frame. I would prefer to have the osg objects interact enough with the openGL drawing to render by depth, but even getting OSG to not occlude everything already drawn would be nice. Thanks for your help, Mark Henderson
