D3DXMatrixMultiplyTranspose function (D3dx9math.h)
Note
The D3DX utility library is deprecated. We recommend that you use DirectXMath instead.
Calculates the transposed product of two matrices.
Syntax
D3DXMATRIX* D3DXMatrixMultiplyTranspose(
_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 is the transposed of the product of two transformation matrices, Out = T(M1*M2).
The return value for this function is the same value returned in the pOut parameter. In this way, the D3DXMatrixMultiplyTranspose function can be used as a parameter for another function.
This function is useful to set matrices as constants for vertex and pixel shaders.
