D3DXMatrixMultiplyTranspose function

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 (left hand side).

pM2 [in]

Type: const D3DXMATRIX*

Pointer to a source D3DXMATRIX structure (right hand side).

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.
