    摘要: Because using the same number of bits per residual depth offset compression is not the best distribution of bits, the bits per residual may be distributed instead according to the content of the depths of a tile. For example, if the depth differences close to the Zmax are small, then fewer bits can be spent on residuals for the samples that are encoded relative to Zmax. Consequently, more bits can be spent on the residuals for the samples that are encoded relative to Zmin. As a result, more tiles succeed at compressing to the required number of bits.

    摘要: In accordance with some embodiments, a tile shader executes on a group of pixels prior to a pixel shader. The tile of pixels may be rectangular in some embodiments. The tile may be executed hierarchically, refining each tile into smaller subtiles until the pixel or sample level is reached. The tile shader program can be written to discard groups of pixels, thereby quickly removing areas of the bounding triangles that lie outside the shape being rasterized or quickly discarding groups of pixel shader executions that will not contribute to the final image.
