math - 如何根据距离找到点的坐标？

Question

我有 2 个点，它们都是 3d 点，即 A(x,y,z) 和 B(x,y,z)。我知道点 a 的坐标和它们之间的距离。如何找到B点的坐标？

非常感谢

Answer 1

If you only know the absolute distance between the two points, you cannot find the coordinates of point B. If you think about it, knowing one point and a distance defines a sphere.

However, if you know the difference between the coordinates in the x, y, and z axes, its as simple as adding the difference to point A to obtain point B.
