Stochastic depth buffer compression using generalized plane encoding |
摘要 |
Unlike a static primitive, where the depth function is planar, the depth function for a moving and defocused triangle is a rational function in time and the lens parameters. Compact depth functions can be used to design an efficient depth buffer compressor/decompressor, which significantly lowers total depth buffer bandwidth usage. In addition, this compressor/decompressor is substantially simpler in the number of operations needed to execute, which makes it more amenable for hardware implementation than previous methods. |

1. A computer executed method comprising:
computing, using a hardware processor depth function coefficients for triangles undergoing at least one of motion blur or depth of field; for each of a plurality of tiles computing, using a hardware processor, per sample coverage; and using the per sample coverage in a hardware tile depth compressor to store compressed depths for samples of a tile. |
