1. An apparatus for graphics processing, comprising:
a memory; and
at least one processor coupled to the memory and, based at least in part on information stored in the memory, the at least one processor is configured to:
obtain visibility information for a set of primitives in at least one frame associated with the graphics processing, wherein 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;
configure a density map based on the visibility information for the set of primitives, wherein the density map includes density data associated with an amount of the set of primitives in each of the plurality of bins; and
map the density data for each of the plurality of bins to a shading rate for each of the plurality of bins.
