Not sure about the science behind light fields? Watch this.

VIDEO 21 min. 20 sec. Gordon Wetzstein, from the Computational Imaging Group at Stanford, explains the use of computational light field displays with a goal of building better quality of 3-D displays than anything known today. The magic happens with high speed patterns that fuse into the 3-D view.
