Wide-field three-dimensional viewing system
First Claim
1. In a stereoscopic display and viewing system, wherein a pair of left and right stereoscopic images are displayed in adjacent side-by-side array on a two dimensional rectangular imaging surface, the improved display and viewing means which comprises:
- (a) left and right stereoscopic images displayed in a sideways fashion on said imaging surface, the two images rotated about the normal to said imaging surface in opposite directions by 90 degrees from their usual upright orientations; and
(b) viewing means comprising a right pair of light deflection means and a left pair of light deflection means, with respective means of support to secure said light deflection means between a viewer and said imaging surface, said light deflection means being held at fixed and predetermined angular relationships so as to deflect the lines of sight to each of a viewer'"'"'s eyes from the respective stereoscopic image, in such a manner that the projected views of the left and right images appear rotated by 90 degrees in opposite directions into a normal upright orientation and shifted so as to appear merged in front of the viewer, thereby creating the stereoscopic illusion of depth from said images.

Abstract
The invention is used with a display (10) of a left and right stereoscopic images in adjacent side-by-side array on a two-dimensional imaging surface such as the screen of a computer monitor or television. The left and right images (L and R) are rotated by 90 degrees in opposite directions from their normal upright orientations. A viewing device which includes a right pair of mirrors (2 and 4) and a left pair of mirrors (1 and 3) is placed between the viewer and the display. The mirrors are oriented at fixed and predetermined angular relationship to deflect the lines of sight from the viewer'"'"'s eyes to the respective right and left images, and to rotate them by 90 degrees. As a result, the users left and right eyes see upright versions of the left and right images, respectively, creating a wide-field stereoscopic illusion of the images.

19. A method for producing left and right stereoscopic images rotated by 90 degrees counter-clockwise and clockwise, respectively, on the left and right halves of a computer monitor with screen width w, screen height h and resolution W pixels by H pixels, where each point (x, y, z) in a three-dimensional space defined in a computer program is mapped onto the two pixels (x1, y1) and (x2, y2) on said monitor according to the following formulas:
- ##EQU4## where L is half of the distance between the viewers eyes, D is the optical distance from the eyes to the screen and where the pixel coordinates x1, y1, x2 and y2 are rounded to the nearest integer values.
