Method for creating and a system for using a constant vertical resolution toroidal display
First Claim
1. A method of producing a toroidal constant vertical resolution surface acting as a rear-projection display screen for receiving and displaying a substantially constant vertical resolution projected image from an image projector, the method comprising:
- identifying an eye-point of a viewer to be positioned behind the rear-projection display screen of the constant vertical resolution surface from the image projector;
identifying a viewing distance from the eye-point of the viewer to an inside surface of the rear-projection display screen of the constant vertical resolution surface in the direction of the image projector;
identifying a projection distance from the image projector to an outside surface of the rear-projection display screen of the constant vertical resolution surface in the direction of the eye-point of the viewer;
creating a constant vertical resolution elevation curve based on a locus of points defined by an intersection ofa set of equal angular increment lines of the viewing distance from the eye-point of the viewer witha set of equal pixel size increment lines of the projected image from the image projector based on the projection distance from the image projector; and
creating the toroidal constant vertical resolution surface defined by at least a portion of the constant vertical resolution elevation curve being at least partially rotated about at least a portion of a central vertical axis intersecting with the eye-point of the viewer to produce a constant vertical resolution surface in a vertical direction as a function of elevation.

Abstract
The present disclosure is generally directed to methods of creating and a visual image projection and display system including a tessellation of toroidal constant vertical resolution surfaces to display a single substantially constant vertical resolution image by blending projected images on adjacent constant vertical resolution surfaces. Each toroidal constant vertical resolution surface is defined by any horizontal section of the constant vertical resolution surface normal to a central vertical axis of the tessellation of constant vertical resolution surfaces being a constant distance from the central vertical axis. The system further includes a top surface screen intersecting the tessellation of toroidal constant vertical resolution surfaces defined by a circular azimuth curve, and a set of image projectors corresponding to each constant vertical resolution surface of the tessellation of toroidal constant vertical resolution surfaces and the top surface screen.
