Splat filtering method, medium, and system

Abstract

A filtering system, medium, and method, including determining whether a size of a splat exceeds a predetermined size, smoothing a boundary of the splat if it is determined that the size of the splat exceeds the predetermined size, and sharpening the boundary of the splat if it is determined that the size of the splat does not exceed the predetermined size.

Claims

1. A filtering method, comprising: determining whether a size of a splat for rendering at least one pixel meets a predetermined size; andsmoothing a boundary of the splat if the size of the splat is determined to meet the predetermined size.

2. The filtering method of claim 1, further comprising super-sampling a generated splat before performing a determining of whether a size of the generated splat exceeds the predetermined limit.

3. The filtering method of claim 1, further comprising: expanding the size of the splat, forming a boundary of a rendered image, by a predetermined ratio, and correcting the boundary using the expanded splat,wherein the splat has a spherical or hemispherical shape.

4. The filtering method of claim 1, wherein the splat has a planar shape and the size of the splat corresponds to an area of the splat.

5. The filtering method of claim 1, wherein the splat has a spherical shape and the size of the splat corresponds to a volume of the splat.

6. A filtering method, comprising: determining whether a size of a splat for rendering at least one pixel meets a predetermined size; andsharpening a boundary of the splat if the size of the splat is determined to not meet the predetermined size.

7. The filtering method of claim 6, further comprising super-sampling a generated splat before performing a determining of whether a size of the generated splat exceeds the predetermined limit.

8. The filtering method of claim 6, further comprising: expanding the size of the splat, forming a new boundary, by a predetermined ratio, and correcting the boundary using the expanded splat,wherein the splat has a spherical or hemispherical shape.

9. The filtering method of claim 6, wherein the splat has a planar shape and the size of the splat corresponds to an area of the splat.

10. The filtering method of claim 6, wherein the splat has a spherical shape, and the size of the splat corresponds to a volume of the splat.

11. A filtering method comprising selectively one of smoothing and sharpening a boundary of a splat for rendering at least one pixel, respectively based on whether a size of a splat meets a predetermined size.

12. A filtering system, comprising: a checking unit to determine whether a size of a splat for rendering at least one pixel meets a predetermined size;a first filtering unit to smooth a boundary of the splat based on a corresponding determination result of the checking unit indicating that the size of the splat meets the predetermined size; anda second filtering unit to sharpen the boundary of the splat based on the corresponding determination of the checking unit indicating that the size of the splat does not meet the predetermined size.

13. The filtering system of claim 12, further comprising: a super-sampling unit to perform a super-sampling on a generated splat for providing the splat to the checking unit.

14. The filtering system of claim 12, further comprising: a boundary correction unit to expanding the size of the splat, forming a boundary of a rendered image, by a predetermined ratio, and to correct the boundary using the expanded splat,wherein the splat has a spherical or hemispherical shape.

15. The filtering system of claim 12, wherein the splat has a planar shape, and the size of the splat corresponds to an area of the splat.

16. The filtering system of claim 12, wherein the splat has a spherical shape, and the size of the splat corresponds to a volume of the splat.

17. At least one medium comprising computer readable code to control at least one processing element to implement the method of claim 1.

18. At least one medium comprising computer readable code to control at least one processing element to implement the method of claim 6.

19. At least one medium comprising computer readable code to control at least one processing element to implement the method of claim 11.
