Some algorithms -- in particular custom antialiasing functions -- depend on the knowledge of, or even require control over the positions of samples within each pixel. The AMD_sample_positions extension added some control over the positions of samples within a single framebuffer. However, it forced all pixels within a framebuffer to have the set of sample positions. This extension provides a mechanism to explicitly set sample positions for a framebuffer object with multi-sampled attachments in a repeating pattern, allowing different pixels to use different sub-pixel locations for their samples. The sample locations used by the FBO can be fixed for all pixels in the FBOs attachments or they can be fixed for a sampling pattern comprised of multiple pixels, where the sampling pattern is repeated over all pixels. The rate of repeat of this sampling pattern size itself is fixed and is implementation-dependent.
