Research on the Accelerated Ray Tracing for Volume-Rendering Based on GPU

Ray Tracing Algorithm is a main algorithm for volume-rendering in photorealistic rendering. This paper designs the algorithm based on stream for GPU, after analyzing the principle of the Ray Tracing on GPU. According to the speed in modeling intersection being slow, realized the improvement of the algorithm on modeling intersection and scene ergodicity. With the result, It was found that the algorithm on GPU is better than on CPU.
