The present disclosure relates to methods and apparatus for graphics processing. The apparatus can determine geometry information for each of a plurality of primitives associated with a viewpoint in a scene. The apparatus can also calculate at least one of surface information and disocclusion information based on the geometry information for each of the plurality of primitives, where the surface information and the disocclusion information may be associated with a volumetric grid based on a viewing area corresponding to the viewpoint. Also, the apparatus can calculate visibility information for each of the plurality of primitives based on at least one of the surface information and the disocclusion information, where the visibility information may be associated with the volumetric grid. The apparatus can also determine whether each of the plurality of primitives is visible based on the visibility information for each of the plurality of primitives.
