功能：已知平面圆弧上两点坐标及圆半径，计算圆心坐标.编程语言：JavaScript分析： 给定圆弧半径，经过平面上两点的圆弧圆心落在两点的中垂线上, 一般有两个.算法:1) 计算两点之间的中点坐标.2）计算连接两点的方向向量.3）将两点方向向量顺时针旋转90度，得到中垂线方向向量.4）单位化中垂线方向向量.5）计算中点与圆心的偏移距离.6）将中点沿中垂线方向移动偏移距离，既...

已知直线过点 m(x_m, y_m, z_m ), 其方向向量为 V_l( vl_x, vl_y, vl_z ).平面过点 n(x_n, y_n, z_n), 法线方向为 V_p( vp_x, vp_y, vp_z ).直线的参数方程为x = x_m + vl_x * ty = y_m + vl_y * tz = z_m + vl_z * t平面方
