📘 About the 3D Midpoint

Find the midpoint of two points in 3D Cartesian space.

🧮 Formula

X
(x1+x2)/2
Y
(y1+y2)/2
Z
(z1+z2)/2

Where

  • x, y, z = coordinates
M = ((x1+x2)/2, (y1+y2)/2, (z1+z2)/2).

✏️ Worked example

(0,0,0) and (6,8,10)

You enter
X10
Y10
Z10
X26
Y28
Z210
You get
Midpoint X3
Midpoint Y4
Midpoint Z5

The midpoint is (3, 4, 5).
