3D data have been collected and 3D models have been constructed for several years in a wide range of applications. Medical science, pharmaceutical research, automotive engineering, CAD/CAE, architecture, scientific data on climate and geography or computer games are only a few examples. However, the means of displaying the third dimension have been very limited. You either had to use special 3D eyewear (which is quite bothersome, especially if you have to wear glasses anyway) or rely on the power of your imagination to add depth to flat images. An autostereoscopic display shows 3D content as it is meant to be seen without special glasses. And while this is useful in the professional field, it also adds greatly to the fun of games and movies.
