How can I get 2D images moving on the screen? I managed to display a static HUD however I can't figure out how to get the cursor graphics moving on screen. I took glance at osgcatch but the code is too complicated (and I'm looking for a quick fix ). To set the HUD position on the screen I feed a osg::geometry object with a coordinates array. Is there a way to move the geometry position at runtime?
You can just add your geode - the one that contains your geometry - as a child of a MatrixTransform or PositionAttitudeTransform. 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
