摘要
基于CyrusBeck算法及长方体面上点的约束条件 ,提出光线跟踪中射线与长方体求交测试和运算法的高效算法 ,显著改善了光线跟踪条件下数控车削加工仿真图形生成速度。该算法具有通用性 。
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.
