Patent ID: 7796134

Claim:
A display system comprising: a non-horizontal first display surface; a horizontal distinct second display surface; a non-horizontal distinct third display surface connecting the first display surface and second display surface; an input device; and one or more processors operable to interact with the input device, the first display surface, and the second display surface to perform operations comprising: performing a first projection of each point of a first 3D object onto a non-horizontal first drawing plane to generate a first projection image in a non-horizontal first perspective for the first display surface, the first projection performed by determining a first set of projection lines that extend through a first eyepoint, the first 3D object, and the first drawing plane, wherein the first drawing plane and the first display surface are mapped to one another and share a common reference plane; performing a distinct second projection of each point of a second 3D object onto a horizontal distinct second drawing plane to generate a distinct second projection image in a horizontal distinct second perspective for the second display surface, the second projection performed by determining a second set of projection lines that extend through a second eyepoint, the second 3D object, and the second drawing plane, wherein the second drawing plane and the second display surface are mapped to one another and share a common reference plane; performing a distinct third projection of each point of the second 3D object onto a non-horizontal distinct third drawing plane to generate a distinct third projection image in a non-horizontal third perspective for the third display surface, the third projection performed by determining a third set of projection lines that extend through a third eyepoint, the second 3D object, and the third drawing plane, wherein the third drawing plane and the third display surface are mapped to one another and share a common reference plane; and displaying the first projection image on the first display surface, concurrently displaying the second projection image on the second display surface, and concurrently displaying the third projection image on the third display surface.
