1. A method comprising: dividing, by a graphics processing device, a compositing region into subregions based on a location of geometry chunks within the compositing region; selecting, by the graphics processing device, one of the subregions based on a correspondence of the one of the subregions to a bounding region for one of the geometry chunks, wherein the bounding region defines an outline of the one of the geometry chunks; communicating the one of the geometry chunks to a graphics unit assigned to the one of the subregions, wherein the graphics unit is configured to render the one of the geometry chunks; and providing the rendered geometry chunk to an output display device.
