摘要： Position-based rendering apparatus and method for multi-die/GPU graphics processing. For example, one embodiment of a method comprises: distributing a plurality of graphics draws to a plurality of graphics processors; performing position-only shading using vertex data associated with tiles of a first draw on a first graphics processor, the first graphics processor responsively generating visibility data for each of the tiles; distributing subsets of the visibility data associated with different subsets of the tiles to different graphics processors; limiting geometry work to be performed on each tile by each graphics processor using the visibility data, each graphics processor to responsively generate rendered tiles; and wherein the rendered tiles are combined to generate a complete image frame.

摘要： A virtual reality apparatus and method are described. For example, one embodiment of an apparatus comprises: a compute cluster comprising global illumination circuitry and/or logic to perform global illumination operations on graphics data in response to execution of a virtual reality application and to responsively generate a stream of samples; a filtering/compression module to perform filtering and/or compression operations on the stream of samples to generate filtered/compressed samples; a network interface to communicatively couple the compute cluster to a network, the filtered/compressed samples to be streamed over the network; a render node to receive the filtered/compressed samples streamed over the network, the render node comprising: decompression circuitry/logic to decompress the filtered/compressed samples to generate decompressed samples; a sample buffer to store the decompressed samples; and sample insertion circuitry/logic to asynchronously insert samples into a light field rendered by a light field rendering circuit/logic.

摘要： An apparatus and method are described for culling commands in a tile-based renderer. For example, one embodiment of an apparatus comprises: a command buffer to store a plurality of commands to be executed by a render pipeline to render a plurality of tiles; visibility analysis circuitry to determine per-tile visibility information for each of the plurality of tiles and to store the visibility information for a first tile in a first storage, the visibility information specifying either that all of the commands associated with rendering the first tile can be skipped or identifying individual commands associated with rendering the first tile that can be skipped; and a render pipeline to read the visibility information from the first storage to determine whether to execute or skip one or more of the commands from the command buffer to render the first tile.
