Foveated rendering in tiled architectures

Abstract:

This disclosure describes examples for foveation rendering. A graphics processing unit (GPU) may render image content for each tile at different sizes as part of the rendering pass after a binning pass in which the GPU determined to which tiles vertices of primitives belong. The GPU may upsample the rendered image content based on the size at which GPU rendered the image content, and output the upsampled image content for later display.
