    Synopsis

    Returns the true angle in degrees from vector v1 to vector v2 in 3-space. A third "normal" vector v3 is used to determine the direction of measurement, using the right-hand rule. Negative angles are not returned.

    Syntax

    angle2Vectors ( v1 As Vector, _
                    v2 As Vector, _
                    v3 As Vector ) As Number 
    Argument Type Description
    v1 Vector start vector
    v2 Vector end vector
    v3 Vector A vector, not in the plane formed by v1 and v2, used to pick between the two choices for angle.

    Example 1

    Intent >angle2Vectors(Vector(1,0,0), Vector(0,1,0), Vector(0,0,1)) 
    --> 90 

    Example 2

    Intent >angle2Vectors(Vector(1,0,0), Vector(0,1,0), Vector(0,0,-1)) 
    --> 270 
    By reversing the bias vector, we obtain the other interpretation of the angle.
