Compact Depth Plane Representation for Sort Last Architectures

摘要

In accordance with some embodiments, a full per sample coverage mask may be used for a subset of the pixels in the tile, thereby enabling pixels that belong to multiple depth ranges to be handled. This makes the depth bounds a tighter fit for the true depth range of the tile and improves hierarchical depth culling efficiency when MSAA is used.

1. A method comprising:
storing a depth plane representation for fully covered tiles; and storing a depth plane representation for partially covered tiles at lower precision than for fully covered tiles stored at higher precision.
