| Abstract: | This paper makes use of the fundamental theory of cones culling in computer graphic and optimizes the technology more based on the exploitation of "RTG three-dimension graphic exploiture saddlebag".Because the thick and thin culling methods about cones are brought forward in the paper,the protracting and romancing speed in the visual field has been greatly improved in big scene.And this provides with very well premise when we exploiture big real-time scene. |
