Compute an angle in 3D space

get_3d_angle(x1, y1, z1, x2, y2, z2, x3, y3, z3)

Arguments

x1

x-coordinate of first point

y1

y-coordinate of first point

z1

z-coordinate of first point

x2

x-coordinate of second point (vertex)

y2

y-coordinate of second point (vertex)

z2

y-coordinate of second point (vertex)

x3

x-coordinate of third point

y3

y-coordinate of third point

z3

z-coordinate of third point

Value

A numeric vector that provides the angular measurement in degrees.

Details

Everything supplied to arguments must be singular numeric values. The second point (x2, y2, z2) is treated as the vertex, and the angle between the three points in 3D space is computed.
