Setting Up the Target

createSceneGraph() in WrapFPShooter3D loads the target using PropManager, places it in the scene, and records its location:

    PropManager propMan = new PropManager(TARGET, true);
    sceneBG.addChild( propMan.getTG() );
    Vector3d targetVec = propMan.getLoc();
    System.out.println("Location of target: " + targetVec );

TARGET is Coolrobo.3ds, and the true argument to the PropManager constructor means that there's a coords datafile that fine-tunes the robot's position. The robot appears facing along the positive z-axis, with its feet resting on the XZ plane, in the middle of the floor. targetVec holds the center point of the shape and is used to calculate if a beam is close enough to the robot to trigger an explosion.
