Quaternion.Multiply Method ()

  • 發行項

Multiplies two quaternions.

Overload List

public void Multiply(Quaternion);
public static Quaternion Multiply(Quaternion, Quaternion);

Remarks

The result represents the rotation m1 followed by the rotation m2 (return value = m1 * m2). This is done so that Multiply maintains the same semantics as Matrix, because unit quaternions can be considered as another way of representing rotation matrices.

Transformations are concatenated in the same order for the Quaternion.Multiply and Matrix.Multiply methods. In the following C# code example, assuming that mX and mY represent the same rotations as qX and qY, both m and q represent the same rotations.

[C#]

m = Matrix.Multiply(mX, mY);

q = Quaternion.Multiply(qX, qY);

The multiplication of quaternions is not commutative; that is, the order in which they are multiplied is important.
