Vector3	pointB	Second corner point.
Vector3	pointC	Third corner point.
Vector3	pointD	Fourth corner point.

Returns

Type	Description
Vector3	The centroid position of the quadrilateral.

CalculateQuadrilateralArea(Vector3, Vector3, Vector3, Vector3)

Calculates the surface area of a quadrilateral by dividing it into two triangles.

Declaration

public static float CalculateQuadrilateralArea(Vector3 pointA, Vector3 pointB, Vector3 pointC, Vector3 pointD)

Parameters

Type	Name	Description
Vector3	pointA	First corner point.
Vector3	pointB	Second corner point.

Calculates the surface area of a triangle using the cross product method.

Declaration

public static float CalculateTriangleArea(Vector3 pointA, Vector3 pointB, Vector3 pointC)

Parameters

Type	Name	Description
Vector3	pointA	First vertex of the triangle.
Vector3	pointB	Second vertex of the triangle.
Vector3	pointC	Third vertex of the triangle.

Returns

Type	Description
float	Surface area of the triangle.
