CONSTANT BUFFER SIZE MULTI-SAMPLED ANTI-ALIASING DEPTH COMPRESSION

CONSTANT BUFFER SIZE MULTI-SAMPLED ANTI-ALIASING DEPTH COMPRESSION

By packing the depth data in a way that is independent of the number of samples, so that memory bandwidth is the same regardless of the number of samples, higher numbers of samples per pixel may be used without adversely affecting buffer cost. In some embodiments, the number of pixels per clock in a...

Zusammenfassung:By packing the depth data in a way that is independent of the number of samples, so that memory bandwidth is the same regardless of the number of samples, higher numbers of samples per pixel may be used without adversely affecting buffer cost. In some embodiments, the number of pixels per clock in a first level depth test may be increased by operating in the pixel domain, whereas previous solutions operated at the sample level.
