1. A pixel cull value compression method comprising; retrieving a cull value for a pixel culling area; receiving an end of graphics processing pipeline occlusion value associated with a prediction area within said pixel culling area, including an end of graphics processing pipeline occlusion value associated with an occluded pixel; segmenting a view volume into regions based upon offsets from the said cull value, wherein said cull value varies from a farthest view plane; determining adjustments to said cull value and associated cull mask based upon which of said regions said end of graphics processing pipeline occlusion value is within; removing pixel values from a graphics pipeline in an electronic system based upon results of an occlusion prediction; suspending said removing until a next frame if a depth value associated with said occlusion value change non-monotonically; and performing continued graphics pipeline processing on remaining pixel wherein remaining pixel values are associated with display illumination.
