Abstract

Methods and systems for dynamically splitting content are disclosed. In some embodiments, content may be received that includes one or more elements to be animated. It may be determined that a size of at least one element of the one or more elements to be animated exceeds a threshold. The at least one element having the size that exceeds the threshold may be split into a plurality of sub-elements. A transform of at least one of the sub-elements may be modified.

Claims

1. A non-transitory computer-readable storage medium storing program instructions, wherein the program instructions are computer-executable to implement:

receiving content that includes one or more elements to be animated;

determining that a size of at least one element of the one or more elements to be animated exceeds a threshold;

splitting the at least one element into a plurality of sub-elements; and

modifying a transform of at least one of the plurality of sub-elements.

2. The non-transitory computer-readable storage medium of claim 1, wherein the program instructions are further computer-executable to implement:

rendering the plurality of sub-elements in a single pass.

3. The non-transitory computer-readable storage medium of claim 1, wherein the content is received as a display list, wherein said splitting includes:

replicating an entry of the at least one element in the display list, wherein said replicating includes replicating a transform associated with the at least one element.

4. The non-transitory computer-readable storage medium of claim 1, wherein said splitting results in each of the plurality of sub-elements having a size that falls below the threshold.

5. The non-transitory computer-readable storage medium of claim 1, wherein said modifying includes adjusting a center point of each of the plurality of sub-elements.

6. The non-transitory computer-readable storage medium of claim 1, wherein said modifying includes modifying an instruction corresponding to the at least one sub-element in an animation timeline associated with the content.

7. The non-transitory computer-readable storage medium of claim 1, wherein the plurality of sub-elements are ordered in a data structure in a same stacking order as the at least one element was originally ordered among the one or more elements to be animated in the data structure.

8. The non-transitory computer-readable storage medium of claim 1, wherein the program instructions are further computer-executable to implement providing a single-pass rendering of the plurality of sub-elements to a graphics processing unit (GPU) configured to composite the rendering for display.

9. The non-transitory computer-readable storage medium of claim 1, wherein said determining, splitting, and modifying is performed at run-time upon receiving the content.

10. The non-transitory computer-readable storage medium of claim 1, wherein said splitting is performed according to a technique that minimizes a number of the plurality of sub-elements.

11. The non-transitory computer-readable storage medium of claim 1, wherein the threshold is a maximum size limit in at least one dimension, wherein the threshold is dependent on a graphics processing unit (GPU) limitation.

12. The non-transitory computer-readable storage medium of claim 1, wherein the program instructions are further computer-executable to implement prior to said determining, determining the threshold based on components of a graphics pipeline.

13. A method, comprising:

receiving content that includes one or more elements to be animated;

determining that a size of at least one element of the one or more elements to be animated exceeds a threshold;

splitting the at least one element into a plurality of sub-elements; and

modifying a transform of at least one of the plurality of sub-elements.

14. The method of claim 13, further comprising rendering the plurality of sub-elements in a single pass.

15. The method of claim 13, wherein the content is received as a display list, wherein said splitting includes:

replicating an entry of the at least one element in the display list, wherein said replicating includes replicating a transform associated with the at least one element.

16. The method of claim 13, wherein said splitting includes splitting the at least one element one or more times until each sub-element falls under the threshold, wherein said splitting is performed according to a technique that minimizes a number of the plurality of sub-elements.

17. The method of claim 13, wherein said modifying includes modifying an instruction corresponding to the at least one sub-element in an animation timeline associated with the content.

18. The method of claim 13, further comprising prior to said determining, determining the threshold based on components of a graphics pipeline.

19. A system, comprising:

at least one processor; and

a memory comprising program instructions, wherein the program instructions are executable by the at least one processor to;

receive content that includes one or more elements to be animated;

determine that a size of at least one element of the one or more elements to be animated exceeds a threshold;

split the at least one element into a plurality of sub-elements; and

modify a transform of at least one of the plurality of sub-elements.

20. The system of claim 19, wherein the program instructions are further executable by the at least one processor to:

render the plurality of sub-elements in a single pass.
