Abstract: Techniques for performing shader operations are provided. The techniques include, performing pixel shading at a shading rate defined by pixel shader variable rate shading (“VRS”) data, and updating the pixel VRS data that indicates one or more shading rates for one or more tiles based on whether the tiles of the one or more tiles include triangle edges or do not include triangle edges, to generate updated VRS data.

Abstract: An apparatus for encoding an image and an apparatus for decoding an image are presented. An image contains one or more regions. For encoding the image, the image is decomposed into one or more regions and a region is evaluated to determine whether the region meets a predetermined compressions acceptability criteria. The region is then encoded in response to the transformed and quantized region meeting the predetermined compression acceptability criteria. For decoding the image, a region of the image is selected and the selected region is decoded using metadata associated with the selected region. The metadata includes transformation quantization settings and information describing an aspect ratio used to compress the region.

Abstract: A technique for performing rasterization and pixel shading with decoupled resolution is provided herein. The technique involves performing rasterization as normal to generate quads. The quads are accumulated into a tile buffer. A shading rate is determined for the contents of the tile buffer. If the shading rate is a sub-sampling shading rate, then the quads in the tile buffer are down-sampled, which reduces the amount of work to be performed by a pixel shader. The shaded down-sampled quads are then restored to the resolution of the render target. If the shading rate is a super-sampling shading rate, then the quads in the tile buffer are up-sampled. The results of the shaded down-sampled or up-sampled quads are written to the render target.

Abstract: A method, apparatus, and a non-transitory computer readable medium for compressing an image including one or more regions are presented. An image is decomposed into one or more regions and a region is evaluated to determine whether the region meets a predetermined compressions acceptability criteria. In response to the region not meeting the predetermined compression acceptability criteria, the region is transformed and quantized. The region is then encoded in response to the transformed and quantized region meeting the predetermined compression acceptability criteria. In response to the transformed and quantized region not meeting the predetermined compression acceptability criteria, transformation and quantization settings are adjusted and the region is transformed and quantized using the adjusted settings. The region is then encoded in response to the predetermined compression acceptability criteria having been reached.

Abstract: A technique for performing rasterization and pixel shading with decoupled resolution is provided herein. The technique involves performing rasterization as normal to generate fine rasterization data and a set of (fine) quads. The quads are accumulated into a tile buffer and coarse quads are generated from the quads in the tile buffer based on a shading rate. The shading rate determines how many pixels of the fine quads are combined to generate coarse pixels of the coarse quads. Combination of fine pixels involves generating a single coarse pixel for each such fine pixel to be combined. The positions of the coarse pixels of the coarse quads are set based on the positions of the corresponding fine pixels. The coarse quads are shaded normally and the resulting shaded coarse quads are modified based on the fine rasterization data to generate shaded fine quads.

Abstract: A method for compressing an image includes decomposing the image into one or more regions. A region of the image is selected to be evaluated. The selected region is transformed and quantized if the region does not meet a predetermined compression acceptability criteria. The predetermined compression acceptability criteria may include a specific bit rate, a specific image quality, or combinations thereof. If the region does not meet the predetermined compression acceptability criteria after the region has been transformed and quantized, then the transformation and quantization settings are adjusted and the region is transformed and quantized using the adjusted settings. The region is then encoded when the predetermined compression acceptability criteria has been reached. The encoding may include additional compression stages.
