Abstract
A display method for producing a plurality of different views of an object scene simultaneously is provided. A series of two-dimensional projections of an object is produced for the plane of a display device. Wavefront interference information, independent of the two-dimensional projections is produced for an intermediate plane. The two-dimensional projections and the wavefront interference information are combined to create a diffraction grating in the display device to provide a holographic image of the object scene from a number of positions relative to the display device.

A method of rendering a holographic image of a three dimensional object, the method comprising the steps of:
- producing a series of two dimensional projections of the object for a plane which is coincident with a plane of a display device;
- producing wavefront interference information, independent of the object data in the series of two dimensional projections of the object, relative to an intermediate plane located at a predetermined position relative to the display device;
- combining the two dimensional projections and the wavefront interference information following said steps of producing the series of two dimensional projections of the object and producing wavefront interference information;
- and
- creating a diffraction grating in the display device following said combining step based upon a combination of the two dimensional projections and the wavefront interference information to thereby provide a holographic image of the object from a number of positions relative to the display device.
