Ray-tracing technology considered mirror reflection, refraction and shadows together, which generated when the light from the analogue lamp-house source and the environment irradiates the surface of objects, since it appears, has been one of the main methods for realistic computer graphics generated. Since the algorithm is simple in principle and easy to use, and also can produce all types of realistic visual effects, it is widely used in various fields of the CAD and graphics.In particular, as the development of virtual reality technology and virtual manufacturing technology, it is proved that ray tracing algorithm is very important as one of the main ways for generating realistic images. However, the higher speed of the algorithm are strongly needed.Paying attention on the acceleration of ray tracing algorithm ,this paper presents a model of accelerated algorithm which is based on the super illumination model of the Phone model ;For the problem of light intersection, the light and surfaces, lighting and Ball as well as light and the intersection rectangular accelerated algorithm are discussed; About technology of the acceleration of the ray tracing technology ,the paper focuses on the common bounding box technology and octree technology, and gives some suggestions for the algorithm improvement; Finally, an example of the ray tracing algorithm simulation is made.
