摘要:
A method and apparatus for deferred rendering of pixel information is accomplished by receiving at least a portion of an object element list (Eg. triangle descriptor list) which contains object element descriptor information for each object to be displayed on at least a portion of the display. Upon receiving this information, z-components of each object element (Eg. triangle) is compared with the other object elements based on pixel location. As the comparisons are being made, the identity of an object element that is visible at a particular pixel location (Eg. in the foreground with respect to other objects) is stored in a manner that corresponds with the particular pixel location. Once the z-components for all of the object elements have been compared, the object elements identified in the memory have pixel information generated therefor.
