| Abstract: | On the basis of a cuboid constraint conditions and the CyrusBeck's algorithm for line clipping,a new algorithm is proposed to find out the intersection point between a ray and a cuboid.The speed of graph generating for NC turning simulation under the eondition of ray tracing is obviously increased.The method is not only efficient,but also suitable to the test and intesection calculation between a ray and an arbitrary convex polyhedron. |
