Returns the third angle associated with a Body 321 rotation sequence from one coordinate system object to another. This angle is referred to as the roll angle, and is used in association with the yaw (1st rotation) and pitch (2nd rotation) angles.
Positive angular displacement is determined by the right-hand rule.
Format
