Abstract
A method for performing occlusion queries is disclosed. The method includes steps of: (a) a graphics processing unit (GPU) using a first depth buffer of a first frame to thereby predict a second depth buffer of a second frame; and (b) the GPU performing occlusion queries for the second frame by using the predicted second depth buffer, wherein the first frame is a frame predating the second frame. In accordance with the present invention, a configuration for classifying the objects into the occluders and the occludees is not required and the occlusion queries for the predicted second frame are acquired in advance at the last of the first frame or the first of the second frame.
