COMPRESSION AND DECOMPRESSION OF GRAPHICS DATA USING PIXEL REGION BIT VALUES

摘要

Techniques related to graphics rendering including techniques for compression and/or decompression of graphics data by use of pixel region bit values are described.

1. A computer-implemented method for providing compression in graphics rendering comprising:
determining a plurality of values associated with individual pixels of a tile of pixels; determining, based at least in part on the tile of pixels, a plurality of pixel regions,wherein each pixel region comprises a corresponding subset of the individual pixels;
determining, for an individual pixel region of the plurality of pixel regions, the subset of values associated with the subset of individual pixels corresponding to the individual pixel region comprises a single distinct value; setting a pixel region value for the individual pixel region to a bit value indicating the individual pixel region comprises the single distinct value; and storing, in memory, graphics data comprising the pixel region value and the single distinct value associated with the individual pixel region.
