It's just a try. Later, I should receive 3d coordinates from an input device that I've never seen :-) (probably a device from Immersion Corporation). Therefore, it would be acceptable to interpolate for example the y-coordinate, letting the other unchanged. > > I recommend looking at the ViewInfo class to get better matrix information > from the scene, or use behaviors to ensure that you are one frame behind > the rendering.
