Determines the product of two matrices.
D3DXMATRIX * D3DXMatrixMultiply( D3DXMATRIX * pOut, CONST D3DXMATRIX * pM1, CONST D3DXMATRIX * pM2 );
Pointer to a D3DXMATRIX structure that is the product of two matrices.
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.
