Title: OCCLUSION QUERY APPARATUS AND METHOD FOR ACCELERATED RENDERING
Abstract:
An apparatus and method are described for occlusion queries for accelerated rendering. For example, one embodiment of a method comprises: performing an occlusion query for a plurality of tiles of an image, the occlusion query to determine whether one or more of the tiles are occluded; generating a bit mask in response to the occlusion query, the bit mask comprising data indicating which of the tiles are occluded; and reading the bit mask when rendering the image to remove work associated with those tiles which are occluded.
