ABSTRACT:
Systems and methods for displaying three-dimensional (3D) images are described. In particular, the systems can include a display block made from a transparent material with optical elements three-dimensionally disposed therein. Each optical element becomes luminous when illuminated by a light ray. The systems can also include a computing device configured to generate two-dimensional (2D) images formatted to create 3D images when projected on the display block, by a video projector coupled to the computing device. The video projector is configured to project the 2D images on the block to create the 3D images by causing a set of the passive optical elements to become luminous. Various other systems and methods are described for displaying 3D images.
