Hi Robert. I have an object that is behind an osg::Switch. The switch will normally be set to all children off. When I turn it on I want to get a callback once a child is drawn. For right now, the child that I am interested in is a osg::Text drawable, so I can use the callbacks associated with drawables. I have been looking at the osgcallback example. Do I want to use a draw callback, update callback, cull callback, or what? I just want to ensure that the object behind the switch actually gets drawn to the screen before I execute the next line of code. You da man.

This all is down to your application, its totally under you control when add elements to the scene and when you render the scene. It that you are using osgviewer and expecting it to behave you want? _______________________________________________ osg-users mailing list [email protected] http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/ _______________________________________________ osg-users mailing list [email protected] http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/
