Abstract

A rendering engine including a first component configured to render warped content that is generated remotely from the rendering engine by applying a warping transformation to stored content according to warping information and a second component configured to inversely warp the rendered warped content according to inverse warping information that corresponds to the warping information to form a reproduction of the stored content is provided. The second component is configured to inversely warp the rendered warped content subsequent to or contemporaneous with the warped content being rendered by the first component.

Claims

1. A rendering engine comprising:

a first component configured to render warped content that is generated remotely from the rendering engine by applying a warping transformation to stored content according to warping information; and

a second component configured to inversely warp the rendered warped content according to inverse warping information that corresponds to the warping information to form a reproduction of the stored content;

wherein the second component is configured to inversely warp the rendered warped content subsequent to or contemporaneous with the warped content being rendered by the first component.

2. The rendering engine of claim 1 wherein the stored content includes plaintext content.

3. The rendering engine of claim 1 wherein the first component is configured to render the warped content by displaying the warped content onto a display surface.

4. The rendering engine of claim 3 wherein the second component includes the display surface, and wherein the display surface is distorted in accordance with the inverse warping information.

5. The rendering engine of claim 3 wherein the second component includes a lens that is distorted in accordance with the inverse warping information, and wherein the wherein the first component is configured to projecting the warped content through the lens and onto the display surface.

6. The rendering engine of claim 3 wherein the warped content is generated using non-uniform gain factors, wherein the second component includes the display surface, and wherein the display surface is configured to compensate for the non-uniform gain factors in accordance with the inverse warping information.

7. The rendering engine of claim 3 wherein the second component includes an ambient light source that is configured to inversely warp the rendered warped content on the display surface.

8. The rendering engine of claim 1 wherein the first component includes an audio player configured to render the warped content by creating an audio signal corresponding to the warped content, and wherein the second component is configured to inversely warp the audio signal as a function of time indicated by the inverse warping information.

9. The rendering engine of claim 1 wherein the first component includes an audio player configured to render the warped content by creating an audio signal corresponding to the warped content, and wherein the second component is configured to inversely warp the audio signal as a function of amplitude indicated by the inverse warping information.

10. A method performed by a processing system, the method comprising:

accessing stored content and warping information that corresponds to an inverse warping component in a first rendering engine; and

generating warped content from the stored content and warping information such that the warped content is usable by the first rendering engine to reproduce the stored content without distortion only in combination with the inverse warping component and is usable by a second rendering engine without the inverse warping component to reproduce the stored content with distortion from the warping information.

11. The method of claim 10 further comprising:

generating the warping information from inverse warping information corresponding to the inverse warping component in the first rendering engine.

12. The method of claim 10 further comprising:

generating inverse warping information corresponding to the warping information such that the inverse warping information is usable by the first rendering engine to configure the inverse warping component; and

providing the inverse warping information to the first rendering engine.

13. The method of claim 10 further comprising:

generating the warped content by visually distorting the stored content such that the warped content is usable by the second rendering engine to reproduce the stored content with visual distortion.

14. The method of claim 10 further comprising:

generating the warped content by acoustically distorting the stored content such that the warped content is usable by the second rendering engine to reproduce the stored content with acoustic distortion.

15. The method of claim 10 wherein the warping information corresponds to a configuration of a non-uniform display surface of the first rendering engine, and wherein the warping information is configured to warp the stored content such that a reproduction of the stored content appears properly when projected onto the display surface.

16. The method of claim 10 wherein the warping information corresponds to a configuration of a lens of a projector in the first rendering engine, and wherein the warping information is configured to warp the stored content such that a reproduction of the stored content appears properly when projected through the lens.

17. An image display system comprising:

a sub-frame generator configured to generate first and second sub-frames from warped content that is generated from stored content remotely from the sub-frame generator;

first and second projectors configured to simultaneously project the first and the second sub-frames, respectively, in at least partially overlapping positions to form an image on a display surface; and

an inverse warping component configured to inversely warp the first and the second sub-frames subsequent to or contemporaneous with being projected by the first and the second projectors such that the image reproduces the stored content on the display surface.

18. The image display system of claim 17 wherein the display surface includes a non-uniform surface that forms the inverse warping component.

19. The image display system of claim 18 wherein the non-uniform surface is configured according to inverse warping information that corresponds to warping information used to generate the warped content.

20. The image display system of claim 17 wherein the first and the second projectors include first and second lenses, respectively, that form the inverse warping component.
