Sony has developed a prototype 360-degree autostereoscopic display called RayModeler, allowing viewers to see full colour volumetric objects from 360-degree. And no special 3D glasses are needed to see the 3D images.
It demonstrated this technology at the SIGGRAPH 2010 convention and the display uses special LED light sources showing 360 unique images to all directions in one-degree separations.
The cylindrical display measures 13cm in diameter and 27cm in height. It has a digital video input port and can be connected to a PC. A graphic processor generates the 3D image in real time.
