Barycentric() public static method

Returns a Vector2 containing the 2D Cartesian coordinates of a point specified in barycentric (areal) coordinates relative to a 2D triangle.

public static Barycentric ( Vector2 &value1, Vector2 &value2, Vector2 &value3, float amount1, float amount2, Vector2 &result ) : void
value1	Vector2	A Vector2 containing the 2D Cartesian coordinates of vertex 1 of the triangle.
value2	Vector2	A Vector2 containing the 2D Cartesian coordinates of vertex 2 of the triangle.
value3	Vector2	A Vector2 containing the 2D Cartesian coordinates of vertex 3 of the triangle.
amount1	float	Barycentric coordinate b2, which expresses the weighting factor toward vertex 2 (specified in value2).
amount2	float	Barycentric coordinate b3, which expresses the weighting factor toward vertex 3 (specified in value3).
result	Vector2	[OutAttribute] The 2D Cartesian coordinates of the specified point are placed in this Vector2 on exit.
return	void
