Abstract: A method, apparatus, and system are described for list texturing being performed over a data path of a graphics pipeline. Input data is received at a graphics pipeline of a graphics processing unit to be processed and generated into a final image to be displayed on a display device of a computer system. Geographic primitives are obtained from processing the input data, and neighbor aggregation of pixels within the geographic primitives is performed. The neighbor aggregation of the pixels includes rendering list texture of the pixels by merging the geographic primitives.

Abstract: A method and apparatus for arranging fragments in a graphics memory. Each pixel of a display has a corresponding list of fragments in the graphics memory. Each fragment describes a three-dimensional surface at a plurality of sample points associated with the pixel. A predetermined number of fragments are statically allocated to each pixel. Additional space for fragment data is dynamically allocated and deallocated. Each dynamically allocated unit of memory contains fragment data for a plurality of pixels. Fragment data are arranged to exploit modem DRAM capabilities by increasing locality of reference within a single DRAM page, by putting other fragments likely to be referenced soon in pages that belong to non-conflicting banks, and by maintaining bookkeeping structures that allow the relevant DRAM precharge and row activate operations to be scheduled far in advance of access to fragment data.

Abstract: In a graphics pipeline, a rasterizer circuit generates fragments for an image having multiple surfaces that have been tessellated into primitive objects, such as triangles. First and second fragments are associated with the same pixel. A merge buffer merges the first fragment with the second fragment when the two fragments belong to the same tessellated surface, the first fragment's primitive is adjacent to the second fragment's primitive, both fragments face either toward or away from the viewer, and the first and second fragment are sufficiently similar that merging is unlikely to introduce visually objectionable artifacts. A frame buffer receives fragments from the merge buffer, stores the fragments, combines the fragments into pixels, and outputs the pixels to a display.
