Abstract

Two-dimensional compositing that preserves the curvatures of non-flat surfaces is disclosed. In some embodiments, a mapping is associated with a two-dimensional rendering that maps a potentially variable portion of the two-dimensional rendering to a canvas. The mapping is generated from a three-dimensional model of the potentially variable portion of the two-dimensional rendering. The potentially variable portion of the two-dimensional rendering is dynamically modified according to the mapping to reflect content comprising the canvas or edits received with respect to the canvas.

First claim

What is claimed is:

1. A method, comprising:
generating a mapping that maps a potentially variable portion of a two-dimensional rendering that is modifiable post rendering to a canvas, wherein the mapping is generated from a three-dimensional model of the potentially variable portion of the two-dimensional rendering; and
storing the generated mapping with the two-dimensional rendering;
wherein the mapping is provided with the two-dimensional rendering from a server to a client and the canvas is composited client-side on the potentially variable portion of the two-dimensional rendering according to the mapping so that pixels comprising content included on the canvas replace corresponding original pixels of the potentially variable portion of the two-dimensional rendering and in a manner that preserves curvatures of non-flat surfaces comprising the potentially variable portion of the two-dimensional rendering.

2. The method of claim 1 , wherein edits on the canvas are composited in real time to dynamically modify the potentially variable portion of the two-dimensional rendering.

3. The method of claim 1 , wherein the mapping comprises UV mapping.

4. The method of claim 1 , wherein the canvas comprises a textured image.

5. The method of claim 1 , wherein the canvas is editable and is used to specify or generate custom content.

6. The method of claim 1 , wherein generating the mapping comprises encoding the mapping.

7. The method of claim 1 , wherein generating the mapping comprises rendering an encoded version of the mapping.

8. A method, comprising:
receiving from a server a two-dimensional rendering and a mapping that maps a potentially variable portion of the two-dimensional rendering that is modifiable post rendering to a canvas, wherein the mapping is generated from a three-dimensional model of the potentially variable portion of the two-dimensional rendering;
displaying the received two-dimensional rendering; receiving an edit on the canvas; and
modifying the displayed two-dimensional rendering client-side to reflect the received edit on the canvas by compositing the canvas on the potentially variable portion of the two-dimensional rendering according to the mapping so that pixels comprising content included on the canvas replace corresponding original pixels of the potentially variable portion of the two-dimensional rendering and in a manner that preserves curvatures of non-flat surfaces.

9. The method of claim 8 , wherein empty portions of the canvas that do not include any content comprise transparent pixels that do not modify corresponding original pixels of the potentially variable portion of the two-dimensional rendering.

10. The method of claim 8 , wherein the edit on the canvas dynamically modifies the displayed two-dimensional rendering in real time.

11. The method of claim 8 , wherein the mapping comprises UV mapping.

12. The method of claim 8 , wherein the canvas is editable and is used to specify or generate custom content.

13. The method of claim 8 , wherein the canvas comprises a textured image.

14. The method of claim 8 , wherein the received mapping is encoded.

15. The method of claim 8 , wherein the mapping comprises a rendering of pixel values encoding spatial coordinates.

16. A system, comprising:
a processor configured to generate a mapping that maps a potentially variable portion of a two-dimensional rendering that is modifiable post rendering to a canvas, wherein the mapping is generated from a three-dimensional model of the potentially variable portion of the two-dimensional rendering; and
a database configured to store the generated mapping with the two-dimensional rendering;
wherein the mapping is provided with the two-dimensional rendering from a server to a client and the canvas is composited client-side on the potentially variable portion of the two-dimensional rendering according to the mapping so that pixels comprising content included on the canvas replace corresponding original pixels of the potentially variable portion of the two-dimensional rendering and in a manner that preserves curvatures of non-flat surfaces comprising the potentially variable portion of the two-dimensional rendering.

17. The system of claim 16 , wherein edits on the canvas are composited in real time to dynamically modify the potentially variable portion of the two-dimensional rendering.

18. The system of claim 16 , wherein the mapping comprises UV mapping.

19. The system of claim 16 , wherein the canvas comprises a textured image.

20. The system of claim 16 , wherein the canvas is editable and is used to specify or generate custom content.

21. The system of claim 16 , wherein to generate the mapping comprises to encode the mapping.

22. The system of claim 16 , wherein to generate the mapping comprises to render an encoded version of the mapping.

23. A system, comprising: a processor configured to:
receive from a server a two-dimensional rendering and a mapping that maps a potentially variable portion of the two-dimensional rendering that is modifiable post rendering to a canvas, wherein the mapping is generated from a three-dimensional model of the potentially variable portion of the two-dimensional rendering;
display the received two-dimensional rendering;
receive an edit on the canvas; and
modify the displayed two-dimensional rendering client-side to reflect the received edit on the canvas by compositing the canvas on the potentially variable portion of the two-dimensional rendering according to the mapping so that pixels comprising content included on the canvas replace corresponding original pixels of the potentially variable portion of the two-dimensional rendering and in a manner that preserves curvatures of non-flat surfaces; and
a memory coupled to the processor and configured to provide the processor with instructions.

24. The system of claim 23 , wherein empty portions of the canvas that do not include any content comprise transparent pixels that do not modify corresponding original pixels of the potentially variable portion of the two-dimensional rendering.

25. The system of claim 23 , wherein the edit on the canvas dynamically modifies the displayed two-dimensional rendering in real time.

26. The system of claim 23 , wherein the mapping comprises UV mapping.

27. The system of claim 23 , wherein the canvas is editable and is used to specify or generate custom content.

28. The system of claim 23 , wherein the canvas comprises a textured image.

29. The system of claim 23 , wherein the received mapping is encoded.

30. The system of claim 23 , wherein the mapping comprises a rendering of pixel values encoding spatial coordinates.

31. A computer program product embodied in a non-transitory computer readable storage medium and comprising computer instructions for:
generating a mapping that maps a potentially variable portion of a two-dimensional rendering that is modifiable post rendering to a canvas, wherein the mapping is generated from a three-dimensional model of the potentially variable portion of the two-dimensional rendering; and
storing the generated mapping with the two-dimensional rendering;
wherein the mapping is provided with the two-dimensional rendering from a server to a client and the canvas is composited client-side on the potentially variable portion of
