    Determinant(NPointI,NPointI,NPointI) Method
    In This Topic
    Calculates the oriented area of the triangle formed by the given points.
    Syntax
    'Declaration
 

    Public Overloads Shared Function Determinant( _
   ByVal a As NPointI, _
   ByVal b As NPointI, _
   ByVal c As NPointI _
) As System.Integer
    'Usage
 

    Dim a As NPointI
Dim b As NPointI
Dim c As NPointI
Dim value As System.Integer
 
value = NGeometry2D.Determinant(a, b, c)
    public static System.int Determinant( 
   NPointI a,
   NPointI b,
   NPointI c
)

    Parameters

    a
    Triangle point 1.
    b
    Triangle point 2.
    c
    Triangle point 3.

    Return Value

    The oriented area of the triangle. If the returned value is positive -> the triplet is counter-clockwise oriented (CCW). If the returned value is negative -> the triplet is clockwise oriented (CW). If the returned value equals zero -> the triplet is collinear.
    Remarks
    The oriented area of the triangle is calculated with the following determinant: | a.x a.y 1 | | b.x b.y 1 | | c.x c.y 1 |
    Requirements
