Paper Abstract:	We present an improved method for direct (without tessellation) rendering of rational Bezier patches that allows efficient parallel implementation. More numerically robust method for adaptive computation of termination criteria in Bezier clipping algorithm is presented. In turn, performance improvement for the method is achieved via clever preclipping patches on scanlines. Finally our implementation achieves real-time performance for the complex scenes with up to hundreds of thousands of patches on the commodity CPU.
