CatmullRom() public static method

Performs a Catmull-Rom interpolation using the specified positions.

public static CatmullRom ( Vector2 value1, Vector2 value2, Vector2 value3, Vector2 value4, float amount ) : Vector2
value1	Vector2	The first position in the interpolation.
value2	Vector2	The second position in the interpolation.
value3	Vector2	The third position in the interpolation.
value4	Vector2	The fourth position in the interpolation.
amount	float	Weighting factor.
return	Vector2
