Degradation Coverage-Based Anti-Aliasing

摘要

In one embodiment the table pointed to by visibility samples in Degradation Coverage-Based Anti-Aliasing is split up so that more values can fit (but each value uses fewer bits). This way, more values can be represented in a pixel, and this leads to better image quality in some embodiments. This also opens up the possibility of using as few as two values per pixel, whereas the CSAA uses four or more. Hence, this also saves bandwidth and therefore, also reduces power consumption in some embodiments.

主权项

1. A method comprising:
generating, using a processor, an antialiasing value table containing rendered values; representing each visibility sample as an index into the value table; and splitting an entry in said value table to hold more from one value.
