| Abstract: | On the basis of a cuboid contraint condition and the Cyrus-Beck s algorithm for line clipping a new algorithm is proposed to find out the intersection point point a ray and a cuboid. The speed of a scenario for NC turning simulation is obviously promoted. The method is not only efficient but also can lead to the test and intersection calculation between a ray and an arbitrary convex polyhedron. |
