Cathode ray sphere: a prototype system to display volumetric three-dimensional images

Details are given on a novel type of display system based on traditional technology and capable of displaying truly three-dimensional computer-generated images that can be viewed concurrently from practically any orientation without the need for special glasses to be worn. The principle of operation is elucidated, data rate requirements are described, the prototype control system hardware is outlined, and pictures of some simple computer-generated shapes that have been displayed are included.
