Abstract
When performing foveated rendering, a graphics processor is controlled to render plural, e.g. three, different resolution versions from the same viewpoint for a scene. The rendered different resolution images are then appropriately combined (composited) to provide the output “foveated” image (output frame) that is displayed.The geometry for the scene is processed and sorted into lists for respective rendering tiles of the images being rendered only once, to provide a single set of tile geometry lists that are then used in common when rendering each respective resolution image.
