Multiplies the two specified quaternions.

Namespace: Microsoft.WindowsMobile.DirectX
Assembly: Microsoft.WindowsMobile.DirectX (in Microsoft.WindowsMobile.DirectX.dll)

Syntax

'Declaration
Public Shared Function Multiply ( _
    m1 As Quaternion, _
    m2 As Quaternion _
) As Quaternion
'Usage
Dim m1 As Quaternion
Dim m2 As Quaternion
Dim returnValue As Quaternion

returnValue = Quaternion.Multiply(m1, m2)

public static Quaternion Multiply(
    Quaternion m1,
    Quaternion m2
)

public:
static Quaternion Multiply(
    Quaternion m1, 
    Quaternion m2
)

static member Multiply : 
        m1:Quaternion * 
        m2:Quaternion -> Quaternion

Parameters

m1
Type: Microsoft.WindowsMobile.DirectX.Quaternion
Source Quaternion structure.

m2
Type: Microsoft.WindowsMobile.DirectX.Quaternion
Source Quaternion structure.

Return Value

Type: Microsoft.WindowsMobile.DirectX.Quaternion
A Quaternion structure that is the product of two quaternions.

Remarks

Transformations are concatenated in the same order for the Multiply and 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.

m = Matrix.Multiply(mX, mY)
q = Quaternion.Multiply(qX, qY)

The multiplication of quaternions is not commutative. The order in which they are multiplied is important.
