Abstract

Techniques are disclosed relating to texture sampling operations. In some embodiments, multi-fetch sampling instructions specify a region of a texture in which multiple samples are to be performed and texture processing circuitry is configured to sample the texture multiple times within the region. In some embodiments, the locations of the samples are determined according to a formula, which may be pseudo-random. In some embodiments, the locations of the samples are jittered to produce stochastic results. In some embodiments, the locations of the samples are determined based on one or more stored sets of samples that have particular properties (e.g., blue noise, in some embodiments). In various embodiments, disclosed techniques may facilitate Monte Carlo sampling.
