Abstract: Aspects presented herein relate to methods and devices for graphics processing including an apparatus, e.g., a GPU or a CPU. The apparatus may obtain visibility information for a set of primitives in at least one frame associated with the graphics processing, where the at least one frame includes a plurality of bins, such that at least one bin of the plurality of bins includes at least one primitive of the set of primitives. The apparatus may also configure a density map based on the visibility information for the set of primitives, where the density map includes density data associated with an amount of the set of primitives in each of the plurality of bins. Further, the apparatus may map the density data for each of the plurality of bins to a shading rate for each of the plurality of bins.

Abstract: Aspects presented herein relate to methods and devices for graphics processing including an apparatus, e.g., a GPU or CPU. The apparatus may divide a current frame of a plurality of frames into a plurality of blocks. The apparatus may also generate an encoding value representing data for each of the plurality of blocks in the current frame. Further, the apparatus may compare the encoding value representing the data for each block in the current frame with a previous encoding value representing previous data for a corresponding block in a previous frame. The apparatus may also store the data for at least one block in the current frame if the encoding value representing the data for the at least one block is not similar to the previous encoding value representing the previous data for at least one corresponding block in the previous frame.
