USC Lab creates 3-D holographic displays |

The ICT Graphics Lab at USC has created a low-cost volumetric 3-D display that brings Princess Leia one step closer to begging Obi-Wan for help. The system projects high-speed video onto a rapidly spinning mirror. As the mirror turns, it reflects a different and accurate image to each potential viewer.
The rendering algorithm can recreate virtual and real scenes with correct occlusion, horizontal and vertical perspective, and shading. Close to 5,000 individual images are reflected every second within the surface area and create a real-space three-dimensional object. Video below.
