Hermite() public static method

Performs a Hermite spline interpolation.

public static Hermite ( Vector2 value1, Vector2 tangent1, Vector2 value2, Vector2 tangent2, float amount ) : Vector2
value1	Vector2	Source position vector.
tangent1	Vector2	Source tangent vector.
value2	Vector2	Source position vector.
tangent2	Vector2	Source tangent vector.
amount	float	Weighting factor.
return	Vector2
