Target independent stenciling in graphics processing

摘要

In an example rendering graphics data includes determining a stencil parameter that indicates a sampling rate for determining a coverage value for each antialiased pixel of a path of an image, determining, separately from the stencil parameter, a render target parameter that indicates a memory allocation for each antialiased pixel of the path, and rendering the path using the stencil parameter and the render target parameter.

1. A method of rendering graphics data, the method comprising:
determining a stencil sampling rate for determining a coverage value for each of one or more antialiased of a path of an image, wherein the stencil sampling rate indicates, for each of the antialiased pixels, a memory allocation in a stencil buffer for storing samples of each of the antialiased pixels sampled at the stencil sampling rate; determining, separately from the stencil sampling rate, a render target parameter having a value that is less than the stencil sampling rate, wherein the render target parameter indicates, for each of the antialiased pixels, a memory allocation in a frame buffer for storing each rendered antialiased pixel of the path; and rendering the path using the stencil sampling rate and the render target parameter.
