Abstract: During the rendering of an image, specific pixels in the image are identified where antialiasing would be helpful. Antialiasing is then performed on these identified pixels, where anti-aliasing is a technique used to add greater realism to a digital image by smoothing jagged edges. This reduces a cost of performing antialiasing by reducing a number of pixels within an image on which antialiasing is performed.

Abstract: One aspect of the disclosure provides a method for rendering an image. The method includes: placing primitives of the image in a screen space; binning the primitives into tiles of the screen space that the primitives touch; and rasterizing the tiles. The aforementioned rasterizing includes shading a subset of the primitives binned to one of the tiles over multiple passes at multiple shading rates, each of the shading rates is based at least on a frequency at which a color being shaded at each pass changes across the screen space, and the subset of the primitives are cached in an on-chip memory of a processor rendering the image between the passes.

Abstract: One aspect of the disclosure provides a method for rendering an image. The method includes: placing primitives of the image in a screen space; binning the primitives into tiles of the screen space that the primitives touch; and rasterizing the tiles at one tile of the tiles at a time. The aforementioned rasterizing includes shading a subset of the primitives binned to the one tile at a first shading rate during a first pass and shading the subset of primitives binned to the one tile at a second shading rate during a second pass, the second shading rate is different from the first shading rate, and the aforementioned placing is performed once while the image is rendered.
