A Rotating Autostereoscopic Display



Talk about cool displays – check out this display from the USC Institute for Creative Technologies. They’ve created a three-dimensional display system that rotates at a very high speed. From the website at the ICT:

The Graphics Lab at the University of Southern California has designed an easily reproducible, low-cost 3D display system with a form factor that offers a number of advantages for displaying 3D objects in 3D. The display is:

  • autostereoscopic – requires no special viewing glasses
  • omnidirectional – generates simultaneous views accomodating large numbers of viewers
  • interactive – can update content at 200Hz

The system works by projecting high-speed video onto a rapidly spinning mirror. As the mirror turns, it reflects a different and accurate image to each potential viewer. Our rendering algorithm can recreate both virtual and real scenes with correct occlusion, horizontal and vertical perspective, and shading.

While flat electronic displays represent a majority of user experiences, it is important to realize that flat surfaces represent only a small portion of our physical world. Our real world is made of objects, in all their three-dimensional glory. The next generation of displays will begin to represent the physical world around us, but this progression will not succeed unless it is completely invisible to the user: no special glasses, no fuzzy pictures, and no small viewing zones.

This thing is beautiful – check out some video:
