A computer graphics array may contain all the information required for a three dimensional display but conventional VDU's (video display units) and printers can only provide a flat image. The problem is approached by converting the computer output into a form suitable for synthesis of a volume hologram. Suitable methods and apparatus are discussed and typical results presented, including CT (computer tomography) scan and radiological architecture applications.
