    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, 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.
