Moving multiple objects
#3

This is a translation of my post in the Portuguese section.

---

Admit that A and B are two points in the 3D space, such that:


A = [a1, a2, a3]
B = [b1, b2, b3]

k[k1, k2, k3], such that k represents the movement of the two aforementioned points in the 3D space.

C and D represent, respectively, the new coordinates of A and B after the translation defined by k is applied to the points.

Thefore, we get:

C = [a1 + k1, a2 + k2, a3 + k3]
D = [b1 + k1, b2 + k2, b3 + k3]

----

Example:

A = [3, 2, 1]
B = [5, 1, 6]

k[6, 2, 6].

C = [9, 4, 7]
D = [11, 3, 12]



To sum this up in one phrase, you just need to make sure that the difference between the coordinates is the same before and after the translation. This concept works in the 2D and 3D space.
