Abstract:
1. A method of producing a uniform resolution image on a tessellation of spherical surfaces acting as rear-projection screens, the method comprising: creating a tessellation of a sphere using spherical surfaces associated with a set of display screens, wherein the tessellation of the spherical surfaces surrounds an eyepoint of a viewer on all sides and a top of the tessellation of the spherical surfaces, wherein each screen in the set of display screens has a selected curvature, wherein a set of projectors generates images for display on the tessellation of the spherical surfaces associated with the set of display screens; identifying the eyepoint of the viewer positioned inside the tessellation of the set of display screens; identifying a viewing distance from the eyepoint to each screen in the set of screens; identifying a projection distance from each projector in the set of projectors to each screen in the set of screens, wherein the selected curvature for each screen is identified based on a relationship between the eyepoint, the viewing distance, and the projection distance, wherein the selected curvature is determined based on a locus of points created by an intersection of lines drawn at equal angular increments from the eyepoint with a set of lines drawn at equal pixel increments at an image source through the projection point; and displaying a full field of view display with a uniform resolution on a surface of the tessellated sphere of display screens.
