17.3 3D Displacements
This type of transformation calculates the displacements x, y, z through the Arithmetic mean of the differences between the origin and the destination. Only a couple of points are necessary.
Formulas:
x′=x+Tx
y′=y+Ty
z′=z+Tz
where:
x', y', z' = x, y, z transformed coordinates.
x, y, z = Original x, y, z coordinates.
Tx = Translation x.
Ty = Translation y.
Tz = Translation z.
