Abstract
Apparatus and method for optimizing a hierarchical depth buffer. For example, one embodiment of a method comprises: rasterizing primitives of a current graphics image to generate pixels; generating coverage data associated with a first primitive to identify pixels in a first tile of pixels which are partially covered or fully covered by the first primitive; estimating potential minimum (min) and maximum (max) values for the first primitive at edges of a bounding box surrounding the first primitive within the first tile; and adjusting the potential min and/or max values to be closer to actual min and/or max values, respectively, upon a determination that the potential min and/or max values identify one or more pixels which are not partially or fully covered by the primitive.
