By further study of GPU architecture and GPU stream programming model. In this paper, uniform grid acceleration structure implements on the GPU stream programming model of the ray tracing. It has a lot of ray intersection calculations in the whole rendering process, reducing the efficiency of the whole scene rendering. Rendering without compromising the quality of the premise, put forward that use hardware accelerated Z-buffer to determine the main ray grating method to improve the efficiency of the main ray generation and its experimental verification.
