摘要:
结合反射线法和高亮线法各自的优缺点,通过对反射线法和高亮线法的简化及改进,提出了面向曲面品质分析的极限反射法。该方法将视点和光源向无穷远处映射,使得视点和光源能够用单位方向矢量v和a唯一确定,从而消除了视点及光源的选取对反射线生成的影响,同时继承了高亮线法计算效率高的特点,能够在现有硬件条件下实现曲面品质分析的交互操作。平面直线光源对应于极限反射线法,平面圆形光源对应于极限反射圆法。最后给出了极限反射法的具体例子。实例表明:极限反射法是一种理想的曲面品质检查方法。
Abstract:
Integrating the respective virtues o f reflection line a lgorithm and high light line algorithm, a simplified and improved infinite re flect ion algorithm for surface qua lity analysis is presen ted. In th is method, the v iewpo int and the ligh t source aremapped to infinity, and then expressed by unit vector v and a un iquely. The effect on the generation of reflection lines ow ing to the selection o f v iew po int and light sources is e lim inated. A t the same tim e, the effic iency o f high light line algo rithm is inherited and the a lternate operation is fulfilled w ith the current hardw are. The inf in ite reflection lines are determ ined by coplanar para llel linear light sources and infinite re flect ion circ les are determ ined by coplanar concentric circles sources. Several examp les based on the infinite reflect ion algorithm are prov ided and the infinite reflect ion a lgorithm is proved to be an ideal algorithm for surface qua lity ana lysis.
