| Abstract: | A clean algorithm for determining whether a ray intersects a triangle, region projection method and hybrid model are presented in this paper. These methods can reduce the time of intersection and accelerate the speed of generation of realistic image. By analysing algorithm and experiments, it is indicated that these methods have better performance than the scan line algorithm. The speed of rendering and the quality of generated image are satisfied. |
