摘要

A method of controlling rendering of a computer image at a plurality of computers includes: controlling a first computer of the plurality of computers to identify a pixel of a tile of the computer image, wherein the identification of the pixel is based on an inter-pixel order; controlling the first computer to identify one or more locations of the pixel, to facilitate sampling of the pixel at the one or more locations thereof, wherein the identification of the one or more locations is based on an intra-pixel computational order corresponding to the first computer; and receiving rendering results corresponding to the one or more locations of the pixel.

In this manner, values of multiple unique random sequences (e.g., values of the subset accessible by rendering engine A, values of the subset accessible by rendering engine B, and values of the subset accessible by rendering engine C) are effectively interleaved across values of the common random sequence 202. In an aspect, the rendering engines may access the random sequence based on its process ID and the number of rendering engines supported by the random sequence. For example, rendering engine A may have a process ID of 0 and the random sequence may support 3 rendering engines. In this example, rendering engine A may access index 0, and subsequent index locations incremented by 3 (the number of supported rendering engines). Similarly, rendering engine B may have a process ID of 1 and may access index 1 and subsequent index locations incremented by 3. Rendering engine C may have a process ID of 2 and may access index 2 and subsequent index locations incremented by 3.
