Abstract

The animation of a border is described. A border associated with a portion of an image is provided. The border comprises pixels and the pixels are animated such that the pixels move in a direction within the border. The direction is configured to identify a location of the portion of the image.

Claims

1. A method, comprising:

using a computer for performing;

providing a border associated with a selected portion of an image, the border comprising a plurality of pixels;

determining a direction of movement for the plurality of pixels according to which side of the border the selected portion of the image is located on; and

animating the plurality of pixels to move in the determined direction within the border.

2. The method of claim 1, further comprising generating in a sequential order a plurality of vertices associated with the border, the sequential order matching the direction of movement of the plurality of pixels within the border.

3. The method of claim 2, further comprising storing the vertices wherein the sequential order of the plurality of vertices is preserved.

4. The method of claim 1, wherein the plurality of pixels move in a rotating direction.

5. The method of claim 1, wherein the border comprises a plurality of line segments, and the direction of movement of the plurality of pixels is parallel to the plurality of line segments comprised within the border.

6. The method of claim 5, wherein the selected portion of the image is located on a side that is perpendicular to the line segments associated with the border.

7. The method of claim 1, wherein the selected portion of the image is located towards a right of the direction of movement of the plurality of pixels.

8. The method of claim 1, wherein the selected portion of the image is located towards a left of the direction of movement of the plurality of pixels.

9. A computer-readable storage medium storing computer instructions executable by a computer to perform:

providing a contour associated with a selected portion of an image; and

determining a direction of rotation for the contour according to which side of the contour the selected portion of the image is located on; and

animating the contour to rotate in the determined direction.

10. The medium of claim 9, wherein the computer instructions are further executable to perform:

reducing the contour into a plurality of vertices; and

storing the plurality of vertices in a sequential order, the sequential order matching the direction of rotation.

11. The medium of claim 9, wherein the contour encloses the selected portion of the image.

12. The medium of claim 9, wherein the contour rotates in a clockwise direction, and the clockwise direction indicates that the selected portion of the image is outside the contour.

13. The medium of claim 9, wherein the contour rotates in a clockwise direction, and the clockwise direction indicates that the selected portion of the image is inside the contour.

14. The medium of claim 9, wherein the contour rotates in a counterclockwise direction, and the counterclockwise direction indicates that the selected portion of the image is outside the contour.

15. The medium of claim 9, wherein the contour rotates in a counterclockwise direction, and the counterclockwise direction indicates that the selected portion of the image is inside the contour.

16. A system, comprising:

a memory configured to store a border processing application;

a processor in communication with the memory, the processor being configured to execute the border processing application stored in the memory, the border processing application comprising program instructions for;

providing a border associated with a selected portion of an image;

providing a texture map;

reducing the border into a plurality of vertices and a plurality of texture coordinates associated with the plurality of vertices;

determining a direction of movement for the texture map according to which side of the border the selected portion of the image is located on;

storing the plurality of vertices and the plurality of texture coordinates in a sequential order, the sequential order matching the determined direction of movement of the texture map; and

communicating the texture map, the plurality of vertices, and the plurality of texture coordinates to a graphics processor;

wherein the graphics processor is in communication with the memory and the processor, and the graphics processor comprises logic to animate the texture map to move according to the sequential order that matches the determined direction within the border.

17. The system of claim 16, wherein the plurality of vertices and the plurality of texture coordinates are communicated to the graphics processor in the sequential order.

18. The system of claim 16, wherein the logic to animate the texture map comprises:

logic configured to map the texture map onto the border; and

logic configured to translate the texture map in the determined direction within the border.

19. The system of claim 16, wherein the logic to animate the texture map comprises:

logic configured to modify the plurality of texture coordinates using a texture transformation matrix, the plurality of texture coordinates that are scaled defining a plurality of modified texture coordinates; and

logic configured to index the texture map based on the plurality of modified texture coordinates.

20. The system of claim 19, wherein the logic configured to modify the plurality of texture coordinates comprises logic configured to translate the plurality of texture coordinates in the determined direction within the border.

21. The system of claim 16, wherein the program instructions for reducing the border comprises program instructions for reducing the border into a minimum number of the plurality of vertices.

22. The system of claim 16, wherein the texture map defines a dotted line.

23. The system of claim 16, wherein the texture map defines a dashed line.

24. A method, comprising:

using a computer for performing;

providing a border associated with a selected portion of an image;

providing a texture map;

determining a direction of movement for the texture map according to which side of the border the selected portion of the image is located on;

generating in a sequential order a plurality of vertices associated with the border to match the determined direction within the border; and

animating the border wherein the texture map moves according to the sequential order that matches the determined direction within the border.

25. The method of claim 24, wherein the animating the border comprises:

mapping the texture map onto the border; and

translating the texture map in the determined direction within the border according to the matching sequential order.
