Vector Axis Angle

Computes the angle between two vectors, AB & CD around around the axis of BC. The first vector AB is treated as the “12 O’clock” up position, looking down the axis towards C, with angles being return in the range of (-Pi, Pi). Clockwise angles are positive and anti-clockwise angles are negative.

Inputs

Name	Type	Description	Default
A	Vector	First vector for the calculation, which draws a line to B	[0.0, 0.0, 0.0]
B	Vector	Second vector for the calculation, which receives a line from A and draws a line to C	[0.0, 0.0, 0.0]
C	Vector	Third vector for the calculation, which receives a line from B and draws a line to D	[0.0, 0.0, 0.0]
D	Vector	Last vector for the calculation, which is the end point of the line from D	[0.0, 0.0, 0.0]

Outputs
