D3DXMatrixMultiply function

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.
