At the NVIDIA GPU Technology Conference (GTC) 2013, which was held in San Jose, CA, from 18 to 21 March, SURVICE announced the release of Rayforce™, a high-performance raytracing library, as an open-source project. Version 2.0 of the library was specifically designed to leverage NVIDIA’s Kepler GPUs and is currently the fastest known raytracer in the world, with performance that can exceed 1 billion rays/second on a single NVIDIA GTX 690 GPU. In addition to providing state-of-the-art raytracing performance, Rayforce™ provides accurate, in-order, multi-hit capabilities required for many physics-based simulations in which path traversal is as important as first-hit ray intersection. SURVICE developed Rayforce™ in support of the U.S. Army Research Laboratory at Aberdeen Proving Ground, MD.
