Abstract

A computing system to obtain an output includes a multi-plane rendering module includes a renderer receives a plurality of graphical objects to generate one or more image planes of object data, a resampler upscales lower resolution image planes to a higher resolution used by the output image, and a rasterizer combine pixels from a common location in the plurality of image planes after each image plane is upsampled to the higher resolution. The renderer receives one of the graphical objects having a location value along a z-axis of the scene, determines which of a plurality of image planes the graphical objects is located using the z-axis location for the graphical object, each of the planes possess a corresponding image resolution, and renders the graphical object into the image plane at the image resolution corresponding determined image plane.
