Then moving your HUD around only takes a change in the Matrix/Vec3-Quat of the transform node. You have to do this change during the update() phase of the main loop; using an update callback is probably the best way. Have a look at the osggeometry example: it has a moving background that uses this technique. -- Thibault _______________________________________________ osg-users mailing list osg-users@openscenegraph.net http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/
