摘要： A system and method for stitching a boundary transition region of a patch produces a graphics primitive topology for the boundary transition region of the patch. A first number of vertices is computed for an inside edge of the boundary transition region using a first tessellation level of detail (LOD) of the inside edge. A second number of vertices is computed for an outside edge of the boundary transition region using a second tessellation LOD of the outside edge. A portion of the first number of vertices and the second number of vertices are merged based on a stitching pattern to produce a set of vertices for the boundary transition region. The set of vertices is stitched to produce an ordered list representing the graphics primitive topology.

摘要： A system and method for performing tessellation in a single pass through a graphics processor divides the processing resources within the graphics processor into sets for performing different tessellation operations. Vertex data and tessellation parameters are routed directly from one processing resource to another instead of being stored in memory. Therefore, a surface patch description is provided to the graphics processor and tessellation is completed in a single uninterrupted pass through the graphics processor without storing intermediate data in memory.

摘要： A graphics processing unit has a set of parallel processing units. A primitive pipeline delivers tiles of a primitive to selected processing units of the set of processing units. An attribute pipeline distributes attributes to the selected processing units when the end of the primitive is reached, while withholding attributes from the remaining processing units of the set of processing units.

摘要： Method and apparatus for providing texture and/or alpha compression. In one embodiment, the present invention incorporates stored palettes, e.g., a luminance palette and a chrominance palette such that, compressed texture data pertaining to a fixed blocksize is decoded and applied to the stored palettes to extract the texel data. In a second embodiment, the present method uses a plane to estimate the alpha value at each of the texels, and a three-bit correction factor to adjust the estimate to produce a final alpha value.

摘要： In a raster stage of a graphics pipeline, a method for rasterizing non-rectangular tile groups. The method includes receiving a graphics primitive for rasterization in a raster stage of a graphics processor. The graphics primitive is rasterized at a first level by generating a non-rectangular footprint comprising a set of pixels related to the graphics primitive. The graphics primitive is then rasterized at a second level by accessing the set of pixels and determining covered pixels out of the set of pixels. The raster stage subsequently outputs the covered pixels for rendering operations in a subsequent stage of the graphics processor.

摘要： A system and method for performing tessellation of three-dimensional surface patches performs some tessellation operations using programmable processing units and other tessellation operations using fixed function units with limited precision. (u,v) parameter coordinates for each vertex are computed using fixed function units to offload programmable processing engines. The (u,v) computation is a symmetric operation and is based on integer coordinates of the vertex, tessellation level of detail values, and a spacing mode.

摘要： A system and method for dividing three-dimensional patches into tasks for processing receives control points defining a three dimensional patch and determines if a number of vertices of the three dimensional patch is greater than a maximum value. When the number of vertices is not greater than the maximum value, the three dimensional patch is output as a single task. When the number of vertices is greater than the maximum value, the three dimensional patch is divided into multiple tasks that each include a number of vertices that is not greater than the maximum value and the multiple tasks are output.
