Multithreaded software rendering pipeline with dynamic performance-based reallocation of raster threads

摘要

A multithreaded rendering software pipeline architecture dynamically reallocates regions of an image space to raster threads based upon performance data collected by the raster threads. The reallocation of the regions typically includes resizing the regions assigned to particular raster threads and/or reassigning regions to different raster threads to better balance the relative workloads of the raster threads.
