    Plane Constructor(Point3D,Point3D,Point3D)
    In This Topic
    Three non-collinear 3D points constructor.
    Syntax
    'Declaration
     
    Public Function New( _
       ByVal P As Point3D, _
       ByVal Q As Point3D, _
       ByVal R As Point3D _
    )
    public Plane( 
       Point3D P,
       Point3D Q,
       Point3D R
    )

    Parameters

    P
    First point (Origin)
    Q
    Second point (X axis)
    R
    Third point
    Remarks
    The Z axis is given by the normalized cross product of PQ and PR, and then the Y axis is obtained by the cross product of Z axis and X axis. So Y axis may not be aligned with PR.
