Stereoscopic imaging
First Claim
1. A method for forming a stereoscopic representation of a three-dimensional object, comprising the steps of:
- (a) providing a stereogram comprising first and second views of the object;
(b) selecting a plurality of pairs of corresponding image points from the first and second views which represent a basic shape of the object;
(c) providing a substrate; and
(d) applying the first and second views to the substrate such that surface parallax is substantially eliminated for each selected pair of corresponding image points, and residual surface parallax occurs for at least some nonselected pairs of corresponding image points.

Abstract
The invention represents a new form of stereoscopically-rendered three-dimensional model and various methods for constructing, manipulating, and displaying these models. The model consists of one or more stereograms applied to a substrate, where the shape of the substrate has been derived from the imagery or from the object itself, and the stereograms are applied to the substrate in a specific way that eliminates parallax for some points and reduces it in others. The methods offered can be (conservatively) 400 times more efficient at representing complex surfaces than conventional modelling techniques, and also provide for independent control of micro and macro parallaxes in a stereoscopically-viewed scene, whether presented in a VR environment or in stereo film or television.

41. Apparatus for forming a stereoscopic representation of an object, comprising:
-
(a) a stereogram comprising first and second views of the object;
(b) a substrate; and
(c) an applicator device for applying the first and second views to the substrate such that surface parallax is substantially eliminated for pre-selected pairs of corresponding image points from the first and second views which represent a basic shape of the object, and residual surface parallax occurs for at least some other pairs of corresponding image points.
