Abstract
A method and system for more efficiently loading a plurality of primitives for a scene into processors of a computer graphics system is disclosed. Each primitive has a top and a bottom. The primitives are ordered based on the top of each primitive. The system and method include providing at least one input, a merge circuit, a distributor, a feedback circuit and a controller. The input(s) is for receiving data relating to each primitive. The merge circuit is coupled with the input(s) and adds the data for a primitive having a top not lower than a current line. The distributor is coupled with the feedback circuit, eliminates an expired primitive and outputs the data for remaining primitives after the expired primitive has been removed. The expired primitive has a bottom above the current line. The feedback circuit is coupled to the merge circuit and the distributor and re-inputs to the merge circuit the data for the remaining primitives. The controller controls the feedback circuit, the distributor and the merge circuit.
