Scientists from the Graphics Lab at the University of Southern California have announced that they have made a breakthrough in 3D technology. They are able to create 3D images that appear to float in mid air. The system uses a mirror mounted on a spinning disk and a projector that is mounted above the disk pointed downwards. As the disk turns, the projector shots images down onto the mirror, which gives a different image for each potential viewpoint. The projector shows a new image for every movement of the spinning mirror, which calculates to over 5000 images per second. The system also is autostereoscopic, which means that viewers do not need polarized glasses to view the 3D image. In addition, the system is also designed to show color images, movement, 3D recreations of scanned objects. Images can also be manipulated by users with a remote control.
