The Quick Start Guide talks about positional state a little bit. Essentially, OpenGL has some state items whose position must be transformed by the current model-view matrix. This is LightSource and ClipPlane (maybe others?). These state items needs to be handled carefully during the cull and draw traversals to ensure they are transformed correctly. PositionalStateContainer supports that handing. -Paul _______________________________________________ osg-users mailing list [email protected] http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/
