To render a scene in a display space, a processor is configured to perform sort-top tiled rendering. To this end, the processor is configured to divide a display space into two or more tiles and assign each tile to a respective graphics core of the processor. Further, the processor is configured to divide a viewport of the scene into corresponding frustums each representing a portion of the viewport in a respective tile. Using a corresponding frustum associated with an assigned tile, each graphics core performs one or more frustum queries to determine one or more graphics objects in a tile to rasterize, one or more draw calls to perform for a tile, or both.
