Abstract: This paper presents a new simple, fast and robust approach in computation of per-sample precise shadows. The method uses tessellation shaders for computation of silhouettes on arbitrary triangle soup. We were able to reach robustness by our previously published algorithm using deterministic shadow volume computation. We also propose a new simplification of the silhouette computation by introducing reference edge testing. Our new method was compared with other methods and evaluated on multiple hardware platforms and different scenes, providing better performance than current state-of-the art algorithms. Finally, conclusions are drawn and the future work is outlined.
