Abstract

A method of creating a reflection effect in an image includes choosing an observer viewpoint; interpolating selected pixels in the image to generate reflection pixels based on the observer viewpoint; and generating a reconstructed image using the selected pixels and the reflection pixels to create the reflection effect.

Claims

1. A method of creating a reflection effect in an image;

comprising

choosing an observer viewpoint;

interpolating selected pixels in said image to generate reflection pixels based on said observer viewpoint; and

generating a reconstructed image using said selected pixels and said reflection pixels.

2. The method of claim 1, further comprising choosing a point of reflection on said image, the pixels of said image that are above said point of reflection being nonsubmerged pixels, and wherein said interpolating said selected pixels is also based on said point of reflection.

3. The method of claim 2, wherein said interpolating said selected pixels is interpolating said nonsubmerged pixels to generate said reflection pixels, and wherein said generating said reconstructed image is generating said reconstructed image using said nonsubmerged pixels and said reflection pixels.

4. The method of claim 1, wherein said interpolating said selected pixels is performed using ray tracing.

5. The method of claim 1, wherein said choosing said observer viewpoint is choosing an observer viewing angle.

6. The method of claim 1, further comprising:

calculating a ripple effect for said reflection pixels; and

incorporating said ripple effect in said reconstructed image.

7. The method of claim 6, further comprising selecting a ripple type, wherein said ripple type is one of a planar ripple, an elliptical ripple, and a circular ripple.

8. The method of claim 6, further comprising selecting at least one ripple source.

9. The method of claim 6, further comprising selecting at least one of a ripple amplitude and a ripple decay function.

10. A method of reconstructing a two-dimensional image to include a reflection effect, said image having a first axis and a second axis, comprising:

incorporating said image in a three-dimensional space defined by said first axis, said second axis, and a third axis;

defining a surface in said three-dimensional space, said surface having non-zero dimensions along said third axis and at least one of said first axis and said second axis;

choosing an observer viewpoint in said three-dimensional space;

selecting a retained portion of said image for use in a reconstructed image;

interpolating the pixels in said retained portion to generate reflection pixels based on said surface and said observer viewpoint; and

generating said reconstructed image using said retained portion of said image and said reflection pixels.

11. The method of claim 10, wherein:

said surface intersects one of said image and an extension of said image in a two-dimensional plane defined by said image, thereby forming an intersection curve, said intersection curve dividing said image into at least two sub-images; and

said retained portion of said image a selected sub-image of said at least two-sub-images.

12. The method of claim 10, wherein said interpolating said pixels in said retained portion is performed using ray tracing.

13. The method of claim 10, wherein said choosing said observer viewpoint is choosing an observer viewing angle in said three-dimensional space.

14. The method of claim 10, further comprising:

calculating a ripple effect for said reflection pixels; and

incorporating said ripple effect in said reconstructed image.

15. The method of claim 14, further comprising selecting a ripple type, wherein said ripple type is one of a planar ripple, an elliptical ripple, and a circular ripple.

16. The method of claim 14, further comprising selecting at least one ripple source.

17. The method of claim 14, further comprising selecting at least one of a ripple amplitude and a ripple decay function.
