Abstract
An occlusion prediction compressing system and method are presented in accordance with embodiments of the present invention. In one embodiment, an occlusion prediction graphics processing method is utilized to predict which pixels are eventually occluded before intermediate processing stages are performed on the pixels. Culling information utilized to predict which pixel are occluded is compressed in accordance with embodiments of the present invention. In one embodiment, a cull value for a pixel culling area is retrieved and an end of pipe depth value associated with a prediction area within the pixel culling area is received. A determination is made if the end of pipe depth value is within a threshold range of the cull value. The cull value is updated based upon the relationship of the end of pipe depth value to offsets from the cull value. The cull value is associated with a mask which indicates if a plurality of prediction areas are at or in front of the cull value.
