D3DXMatrixMultiply function (D3dx9math.h)
Note
The D3DX utility library is deprecated. We recommend that you use DirectXMath instead.
Determines the product of two matrices.
Syntax
D3DXMATRIX* D3DXMatrixMultiply(
_Inout_ D3DXMATRIX *pOut,
_In_ const D3DXMATRIX *pM1,
_In_ const D3DXMATRIX *pM2
);
Parameters
-
pOut [in, out]
-
Type: D3DXMATRIX*
Pointer to the D3DXMATRIX structure that is the result of the operation.
-
pM1 [in]
-
Type: const D3DXMATRIX*
Pointer to a source D3DXMATRIX structure.
-
pM2 [in]
-
Type: const D3DXMATRIX*
Pointer to a source D3DXMATRIX structure.
Return value
Type: D3DXMATRIX*
Pointer to a D3DXMATRIX structure that is the product of two matrices.
Remarks
The result represents the transformation M1 followed by the transformation M2 (Out = M1 * M2).
The return value for this function is the same value returned in the pOut parameter. In this way, the D3DXMatrixMultiply function can be used as a parameter for another function.
