D3DXMatrixMultiply Function

Determines the product of two matrices.

Syntax

D3DXMATRIX *D3DXMatrixMultiply(      

    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 Value

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.
