signedAngleTo Method

Return the (strongly-typed) angle from this vector to vectorB, measured in their containing plane whose normal lies in the same half-space as vectorW.

• The returned angle is between -180 and 180 degrees.
• If the cross product of this vector and vectorB lies on the same side of the plane as vectorW, this function returns angleTo(vectorB); otherwise, it returns -angleTo(vectorB).
• vectorW does not have to be perpendicular to the plane.
• Use planarAngleTo to measure the angle between vectors that are projected to another plane.
