摘要
利用直线在两个坐标平面内的投影将二维直线生成的分段画线算法推广到三维空间,得到空间直线的生成算法.比较传统的三维直线生成算法效率更高,精度较好,可用于三维图形图像的处理、数控加工的空间直线插补和运动控制等方面.
A new segement algorithm is introduced to create 2D lines, then it is developed from 2D to 3D for generation of spatial lines with the method of projections of line segments on xy and xz coordinate planes. Through the comparison of this algorithm with the traditional methods,it is found tobe more accurate and more efficient, and can be used in 3D graphic process, interpolation of spatial line in NC program, and movement control of an object,etc.
