Abstract

A system includes a computing device that includes a memory for storing one or more computer graphics, and a graphics distorter. The graphics distorter applies a distortion model to the computer graphic to produce a distorted version of the computer graphic, while substantially simultaneously allowing user interactions with the computer graphic. The applied distortion model represents lens distortion.

Claims

1. A computer-implemented method comprising:

applying a distortion model to a computer graphic to produce a distorted version of the computer graphic, while substantially simultaneously allowing user interactions with the computer graphic, wherein the applied distortion model represents lens distortion, and includes a reduced sample set, a size of the reduced sample set determined using a predefined threshold that is based upon a comparison of the reduced sample set distortion model and a distortion model that includes a complete sample set.

2. The computer-implemented method of claim 1, further comprising:

combining the distorted computer graphic with an image captured with a lens, wherein the distortion model represents distortion provided by the lens.

3. The computer-implemented method of claim 1, wherein user interactions include manipulating the computer graphic as the distortion model is applied.

4. The computer-implemented method of claim 1, wherein the predefined threshold represents the difference between a pixel represented in the reduced sample set distortion model and a pixel represented in the complete sample set distortion model.

5. The computer-implemented method of claim 1, wherein the predefined threshold represents a fraction of a pixel.

6. The computer-implemented method of claim 1, wherein applying the distortion model to the computer graphic includes repetitively applying the distortion model during user interactions with the computer graphic.

7. The computer-implemented method of claim 1, wherein the computer graphic includes a computer generated three dimensional object.

8. The computer-implemented method of claim 1, wherein the computer graphic includes an image.

9. The computer-implemented method of claim 1, wherein the computer graphic represents a user selection device.

10. The computer-implemented method of claim 1, wherein the distorted version of the computer graphic has a relatively low resolution.

11. A system comprising:

a computing device comprising;

a memory for storing at least one computer graphic; and

a graphics distorter for applying a distortion model to the computer graphic to produce a distorted version of the computer graphic, while substantially simultaneously allowing user interactions with the computer graphic, wherein the applied distortion model represents lens distortion, and includes a reduced sample set, a size of the reduced sample set determined using a redefined threshold that is based upon a comparison of the reduced sample set distortion model and a distortion model that includes a complete sample set.

12. The system of claim 11, wherein the computing device further includes:

a graphics package for combining the distorted computer graphic with an image captured with a lens, wherein the distortion model represents distortion provided by the lens.

13. The system of claim 11, wherein user interactions include manipulating the computer graphic as the distortion model is applied.

14. The system of claim 11, wherein the predefined threshold represents the difference between a pixel represented in the reduced sample set distortion model and a pixel represented in the complete sample set distortion model.

15. The system of claim 11, wherein the predefined threshold represents a fraction of a pixel.

16. The system of claim 11, wherein applying the distortion model to the computer graphic includes repetitively applying the distortion model during user interactions with the computer graphic.

17. The system of claim 11, wherein the computer graphic includes a computer generated three dimensional object.

18. The system of claim 11, wherein the computer graphic includes an image.

19. The system of claim 11, wherein the computer graphic represents a user selection device.

20. The system of claim 11, wherein the distorted version of the computer graphic has a relatively low resolution.

21. A computer program product tangibly embodied in an information carrier and comprising instructions that when executed by a processor perform a method comprising:

applying a distortion model to a computer graphic to produce a distorted version of the computer graphic, while substantially simultaneously allowing user interactions with the computer graphic, wherein the applied distortion model represents lens distortion, and includes a reduced sample set, a size of the reduced sample set determined using a predefined threshold that is based upon a comparison of the reduced sample set distortion model and a distortion model that includes a complete sample set.

22. The computer program product of claim 21, further comprising instructions that when executed by the processor perform a method comprising:

combining the distorted computer graphic with an image captured with a lens, wherein the distortion model represents distortion provided by the lens.

23. The computer program product of claim 21, wherein user interactions include manipulating the computer graphic as the distortion model is applied.

24. The computer program product of claim 21, wherein the predefined threshold represents the difference between a pixel represented in the reduced sample set distortion model and a pixel represented in the complete sample set distortion model.

25. The computer program product of claim 21, wherein the predefined threshold represents a fraction of a pixel.

26. The computer program product of claim 21, wherein applying the distortion model to the computer graphic includes repetitively applying the distortion model during user interactions with the computer graphic.

27. The computer program product of claim 21, wherein the computer graphic includes a computer generated three dimensional object.

28. The computer program product of claim 21, wherein the computer graphic includes an image.

29. The computer program product of claim 21, wherein the computer graphic represents a user selection device.

30. The computer program product of claim 21, wherein the distorted version of the computer graphic has a relatively low resolution.
