Abstract
A method for implementing a graphics pipeline. The method includes determining a plurality of light sources affecting a virtual scene. Geometries of objects of an image of the scene is projected onto a plurality of pixels of a display from a first point-of-view. The pixels are partitioned into a plurality of tiles. A foveal region of highest resolution is defined for the image as displayed, wherein a first subset of pixels is assigned to the foveal region, and wherein a second subset of pixels is assigned to a peripheral region that is outside of the foveal region. A first set of light sources is determined from the plurality of light sources that affect one or more objects displayed in a first tile that is in the peripheral region. At least two light sources from the first set is clustered into a first aggregated light source affecting the first tile when rendering the image in pixels of the first tile.
