ARVROrigin is special spatial node that acts as our origin point mapping our real world center of our tracking volume into our virtual world.
It is this point that you will move around the world as the player 'moves while standing still', i.e. the player moves through teleporting or controller inputs as opposed to physically moving.
Our camera and controllers will always be child nodes and thus place relative to this origin point.
This node will automatically locate any camera child nodes and update its position while our ARVRController node will handle tracked controllers.
