D3DXMatrixMultiply

Determines the product of two matrices.

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 Values

Pointer to a D3DXMATRIX structure that is the product of two matrices.

Remarks

The result represents the transformation M2 followed by the transformation M1 (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.

Requirements

  Header: Declared in D3dx8math.h.
  Import Library: Use D3dx8.lib.
