Ray-tracing is the technique that rendering images from a three dimensional model of a scene by projecting it on to a two dimensional image plane.In the past decades,the development of the computer graphic(especial for raster graphics systems) emphasize on building the high-efficient,low-cost large graphic systems.For the above-mentioned reasons such as the implementation of a large number of mathematical calculation,the large-scale parallel processing technologies play a important role in graphics compose.The principle of ray-tracing algorithm is introduced.A ray-tracing parallel processing model is built through the research on GPU stream processing and MPICH,and it is proved that applying this mode reduces computation time effectively and the quality of the generated graph holds no difference with that by traditional stand-alone computer.
