A display is partitioned into a plurality of cells. Each of the plurality of cells includes a depth interval and a coverage for each of a plurality of surfaces having coverage within the cell. A depth interval and a coverage for a group of pixels having coverage within one or more of the cells is received. Visibility of the group of pixels, for each of the one or more cells, is determined based on comparisons of the depth interval of the group of pixels with the depth intervals of the plurality of surfaces.
