I have the coordinates of two points, which can be considered the extremes of a segment. What formula can I use to divide this segment into X equal parts (X is decided at will) and get the coordinates of their ends?

cartestian is just your normal 3d space, so nothing special there.

Make vectors from the 2 points. (A and B)

//make a vector from A and B
R = B - A

//multiply vector by the scalar T
//T is in [0,1]
//S is a vector
S = R*t

Just interpolate along T to get a new segment.
