工作中遇到两平面求相交直线方程的问题:
已知两个平面的方程为:
平面 1: 15274.32X + 16334.64Y + 3910347.7Z -1217342147660.14 = 0
平面 2: -14272.59X + -32556.69Y + 3899632.2Z + 1993749987653.63 = 0
如何何求点向式的直线方程?
我问了 chatGPT 代码如下:
def line_intersect(p1, p2): """ Finds the line of intersection between two planes given their equations in the form ax + by + cz = d. Returns the direction vector of the line and a point on the line. """ a1, b1, c1, d1 = p1 a2, b2, c2, d2 = p2 # Compute the direction vector of the line of intersection direction = (b1 * c2 - b2 * c1, a2 * c1 - a1 * c2, a1 * b2 - a2 * b1) # Find a point on the line of intersection x = (b1 * d2 - b2 * d1) / (a1 * b2 - a2 * b1) y = (a2 * d1 - a1 * d2) / (a1 * b2 - a2 * b1) z = 0 if c1 != 0: z = d1 / c1 elif c2 != 0: z = d2 / c2 return direction, (x, y, z) 我数学基础较差,都不知道给的答案对不对,恳请各位大佬给解答一下,谢谢。
