<!-- Simple Heads-Up Display (HUD) Prototype\n \n Manages the display of a HUD and maintains its position on the screen.\n Changes to fieldOfView (in Viewpoint node) will change screen position\n \n Fields:\n hudSize Size of HUD (initializeOnly - SFVec3f) default="1 1 .01"\n hudColor Color of HUD (inputOutput - SFColor) default="1 1 1"\n screenOffset Offset of HUD. This field positions the HUD on the display screen (inputOutput - SFVec3f) default="0 0 0"\n hudGeometry Geometry to be placed on the HUD. Origin is center of HUD. (inputOutput - MFNode) default = []\n position_changed Current viewer location (outputOnly - SFVec3f)\n orientation_changed Current viewer orientation (outputOnly - SFRotation)\n \n \n -->
