Color Buffer Compression |
摘要 |
In accordance with some embodiments, a mask or table may be maintained to record information about whether or not each pixel within a tile is cleared. As used herein, a “cleared” tile is one that is not covered by any other depicted objects. The clear mask may store a bit per pixel or sample to indicate whether the pixel or sample contains a color value or whether it is cleared. As a result, the compression ratio may be increased for partially covered tiles in some embodiments. |
