摘要： An apparatus and method are described for texture space shading. For example, one embodiment of a method comprises: performing texture mapping to map one or more textures to surfaces of one or more objects in texture space within a ray tracing architecture; and performing sampling and reconstruction directly on the surfaces of the objects in the texture space.

摘要： A graphics processing apparatus and method are described. For example, one embodiment of a graphics processing apparatus comprises: an input assembler of a graphics pipeline to determine a first set of triangles to be drawn based on application-provided parameters; a depth buffer to store depth data related to the first set of triangles; a vertex shader to perform position-only vertex shading operations on the first set of triangles in response to an indication that the graphics pipeline is to initially operate in a depth-only mode; a culling and clipping module to read depth values from the depth buffer to identify those triangles in the first set of triangles which are fully occluded by other objects in a current frame and to generate culling data usable to cull occluded triangles, the culling and clipping module to associate the culling data with a replay token to be used to identify a subsequent rendering pass through the graphics pipeline; the input assembler, upon detecting the replay token in the subsequent rendering pass, to access the culling data associated therewith to remove culled triangles from the first set of triangles to generate a second set of triangles; the vertex shader to perform full vertex shading operations on the second set of triangles during the subsequent rendering pass, the replay token to be destroyed during or following the subsequent rendering pass.

摘要： An apparatus and method are described for a non-uniform rasterizer. For example, one embodiment of an apparatus comprises: a graphics processor to process graphics data and render images using the graphics data; and a non-uniform rasterizer within the graphics processor to determine different resolutions to be used for different regions of an image, the non-uniform rasterizer to receive a plurality of polygons to be rasterized and to responsively rasterize the polygons in accordance with the different resolutions.

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 subdividing swap chains using partitions. For example, one embodiment of an apparatus comprises: a graphics processing unit (GPU) to process graphics commands and responsively render a plurality of image frames; partition management logic to subdivide each of the image frames into at least two partitions and to designate each partition in each image frame as being in a front buffer or in a back buffer; the GPU to perform rendering operations to partitions designated as being in the back buffer; and a display link to concurrently perform a scan-out of scan lines from partitions designated as being in a front buffer.
