    Abstract: A system, process, and computer program product are provided for sampling a hierarchical depth map. An approach for sampling the hierarchical depth map includes the steps of generating a hierarchical depth map and reading a value associated with a sample pixel from a target level of the hierarchical depth map based on a difference between the sample pixel and a target pixel. The hierarchical depth map includes at least two levels.

    Abstract: A system, method, and computer program product are provided for tiled deferred shading. In operation, a plurality of photons associated with at least one scene are identified. Further, a plurality of screen-space tiles associated with the at least one scene are identified. Additionally, each of the plurality of screen-space tiles capable of being affected by a projection of an effect sphere for each of the plurality of photons are identified. Furthermore, at least a subset of photons associated with each of the screen-space tiles from which to compute shading are selected. Moreover, shading for the at least one scene is computed utilizing the selected at least a subset of photons.
