ABSTRACT:
A method and system for improving data coherency in a parallel rendering system is disclosed. Specifically, one embodiment of the present invention sets forth a method, which includes the steps of receiving a common input stream, tracking a periodic event associated with the common input stream, generating a plurality of fragment streams from the common input stream, inserting a marker based on an occurrence of the periodic event in a first fragment stream in the multiple fragment streams, and utilizing the marker to influence the processing of the first fragment stream so that a plurality of raster operation (ROP) request streams maintains substantially the same coherence as the common input stream. Each fragment stream is independently processed and corresponds to one of the ROP request streams.
