D3DXMatrixMultiplyTranspose

Calculates the transposed product of two matrices.

D3DXMATRIX * D3DXMatrixMultiplyTranspose(
  D3DXMATRIX* pOut,
  CONST D3DXMATRIX* pM1,
  CONST D3DXMATRIX* pM2
);

Parameters

pOut

[in, out] Pointer to the D3DXMATRIX structure that is the result of the operation.

pM1

[in] Pointer to a source D3DXMATRIX structure.

pM2

[in] Pointer to a source D3DXMATRIX structure.

Return Values

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.
