Abstract

Systems, methods, and computer program products receive an image request identifying an image having a width and a height. A number of interleaved buffers is identified, each of the interleaved buffers operable to store data associated with the image. The image is split into each of the interleaved buffers on a computing device. An interleaved image is displayed corresponding to at least one of the interleaved buffers, where the interleaved image having substantially the same width and height of the image.

Claims

1. A method performed by a system of one or more computers, the method comprising:

receiving an image request identifying an image having a width and a height and being at a first resolution;

identifying a plurality of interleaved buffers, each of the interleaved buffers operable to store data associated with the image and representing a whole view of the image, wherein the whole view includes a full frame of the image at a second resolution that is different from and less than the first resolution;

determining a respective camera offset angle for each interleaved buffer based at least in part on a total number of interleaved buffers of the plurality of interleaved buffers;

splitting the image into each of the interleaved buffers using different sampling rates for two or more of the interleaved buffers, including, for each interleaved buffer, sampling the image using the determined respective camera offset angle for a respective interleaved buffer;

rendering a first representation of the image based on the contents of a first interleaved buffer using the respective offset camera angle for the first interleaved buffer;

displaying the first representation of the image;

after displaying the first representation and while the first representation is still being displayed, rendering a second representation of the image based on the contents of a second interleaved buffer using the respective offset camera angle for the second interleaved buffer;

blending the second representation of the image with the first representation of the image to create an interleaved image; and

displaying the interleaved image in place of the first representation of the image.

2. The method of claim 1, further comprising iteratively displaying interleaved images corresponding to two or more of the interleaved buffers.

3. The method of claim 1, wherein identifying the plurality of interleaved buffers further comprises determining a number of interleaved buffers based on a size of the image.

4. The method of claim 1, wherein identifying the plurality of interleaved buffers further comprises determining a number of interleaved buffers based on a user input.

5. The method of claim 1, further comprising applying a blur filter to the interleaved image prior to displaying the interleaved image.

6. The method of claim 1, wherein the first image and the second image have a number of pixels, and wherein blending the second representation of the image with the first representation of the image results in the interleaved image having twice the number of pixels.

7. The method of claim 1, wherein the interleaved image has the width and the height of the image.

8. The method of claim 1, wherein rendering the first representation of the image comprises performing ray tracing.

9. The method of claim 1 wherein the number of interleaved buffers is two or more and wherein data from a interleaved buffer is provided to a frame buffer to enable display to the user and wherein each of the interleaved buffers is initially rendered using a first technique to produce a faster but lower quality rendering of contents of a respective interleaved buffer and after an the initial rendering are re-rendered using a second different technique to produce a slower but higher quality rendering of the contents of the respective interleaved buffers and wherein upon re-rendering of a given respective interleaved buffer results are blended with a then presented image that is included in the frame buffer.

10. A computer program product, encoded on a computer-readable storage device, operable to cause data processing apparatus to perform operations comprising:

receiving an image request identifying an image having a width and a height and being at a first resolution;

identifying a plurality of interleaved buffers, each of the interleaved buffers operable to store data associated with the image and representing a whole view of the image, wherein the whole view includes a full frame of the image at a second resolution that is different from and less than the first resolution;

determining a respective camera offset angle for each interleaved buffer based at least in part on a total number of interleaved buffers of the plurality of interleaved buffers;

splitting the image into each of the interleaved buffers using different sampling rates for two or more of the interleaved buffers, including, for each interleaved buffer, sampling the image using the determined respective camera offset angle for a respective interleaved buffer;

rendering a first representation of the image based on contents of a first interleaved buffer using the respective offset camera angle for the first interleaved buffer;

displaying the first representation of the image;

after displaying the first representation and while the first representation is still being displayed, rendering a second representation of the image based on the contents of a second interleaved buffer using the respective offset camera angle for the second interleaved buffer;

blending the second representation of the image with the first representation of the image to create an interleaved image; and

displaying the interleaved image in place of the first representation of the image.

11. The computer program product of claim 10, the operations further comprising iteratively displaying interleaved images corresponding to two or more of the interleaved buffers.

12. The computer program product of claim 10, wherein identifying the plurality of interleaved buffers further comprises determining a number of interleaved buffers based on a size of the image.

13. The computer program product of claim 10, wherein identifying the plurality of interleaved buffers further comprises determining a number of interleaved buffers based on a user input.

14. The computer program product of claim 10, further operable to cause data processing apparatus to perform operations comprising:

applying a blur filter to the interleaved image prior to displaying the interleaved image.

15. The computer program product of claim 10, wherein the first representation of the image and the second representation of the image have a number of pixels, and wherein blending the second representation of the image with the first representation of the image results in the interleaved image having twice the number of pixels.

16. The computer program product of claim 10, wherein the interleaved image has the width and the height of the image.

17. The computer program product of claim 10, wherein rendering the first representation of the image comprises performing ray tracing.

18. The computer program product of claim 10 wherein the number of interleaved buffers is two or more and wherein data from a interleaved buffer is provided to a frame buffer to enable display to the user and wherein each of the interleaved buffers is initially rendered using a first technique to produce a faster but lower quality rendering of contents of a respective interleaved buffer and after an the initial rendering are re-rendered using a second different technique to produce a slower but higher quality rendering of the contents of the respective interleaved buffers and wherein upon re-rendering of a given respective interleaved buffer results are blended with a then presented image that is included in the frame buffer.
