Overview. Today, most commercially available 3D display systems require the viewers to wear some sort of shutter-or polarization glasses, which is often regarded as inconvenience. Ideally, a 3D display system should not require the users to wear additional gear. In fact, the optimum would be a display that replicates the original light-field of a scene. So-called multiview aütostereoscopic displays (MADs) represent a step in this direction, as they are able to project several views of a scene simultaneously, enabling a glasses-free 3D experience and a limited motion parallax effect in horizontal direction.
