A Real-time Parallel Ray-tracing Method Based On GPU Cluster

With the fast development of computer and graphic technology, graphics rendering technologies are widely used in 3d simulation, virtual reality etc.Protection of cultural relics. Software and hardware technology of graphics update every day, however, single PC computer still cannot afford high realistic real-time rendering of high complex scene. Ray-tracing algorithm has a very good sense of reality, as it can simulate various optical effects, such as shadow, reflection, refraction and so on. However most of the ray tracing algorithms are non-real-time, because of their high computational cost. In this paper, a real-time parallel ray-tracing method based on GPU cluster is described in detail and the experiment is tested.
