Inside testing for paths |
August 5, 2008 |
| Systems and methods for identifying pixels that are inside a two-dimensional path may be used to fill the path. The path is segmented and a point in space is identified that is used to generate a triangle fan, where each triangle in the fan is formed by one of the segments of the pat |

Decompression of block encoded texture data |
June 10, 2008 |
| Systems and methods that decompress block compressed texture data may decompress the texture data while simplifying computations to reduce die area while maintaining the required accuracy. Reducing the die area permits more texture data to be decompressed in the same die area compare |

Scalable shader architecture |
June 10, 2008 |
| A scalable shader architecture is disclosed. In accord with that architecture, a shader includes multiple shader pipelines, each of which can perform processing operations on rasterized pixel data. Shader pipelines can be functionally removed as required, thus preventing a defective |

Anisotropic texture filtering with a modified number of texture samples |
May 13, 2008 |
| Systems and methods for modifying the number of texture samples used to produce an anisotropically filtered texture mapped pixel may improve texture mapping performance. When the number of texture samples is reduced, fewer texels are read and fewer filtering computations are needed t |

System, apparatus and method for subpixel shifting of sample positions to anti-alias computer-ge |
May 6, 2008 |
| A system, apparatus, and method are disclosed for modifying positions of sample positions for selectably oversampling pixels to anti-alias non-geometric portions of computer-generated images, such as texture, at least in part, by translating (e.g., shifting) shading sample positions |

System and method for virtual coverage anti-aliasing |
February 19, 2008 |
| A graphics system has a mode of operation in which real samples and virtual samples are generated for anti-aliasing pixels. Each virtual sample identifies a set of real samples associated with a common primitive that covers a virtual sample location within a pixel. The virtual sample |

Antialiasing using hybrid supersampling-multisampling |
November 22, 2005 |
| Hybrid sampling of pixels of an image involves generating shading values at multiple shading sample locations and generating depth values at multiple depth sample locations, with the number of depth sample locations exceeding the number of shading sample locations. Each shading sample |
