ID3DXMatrixStack::MultMatrix Method

Determines the product of the current matrix and the given matrix.

Syntax

HRESULT MultMatrix(      

    CONST D3DXMATRIX *pMat
);

Parameters

pMat
[in] Pointer to the D3DXMATRIX structure to be multiplied with the current matrix.

Return Value

If the method succeeds, the return value is D3D_OK.
If the method fails, the return value can be D3DERR_INVALIDCALL.

Remarks

This method right-multiplies the given matrix to the current matrix (transformation is about the current world origin).
m_pstack[m_currentPos] = m_pstack[m_currentPos] * (*pMat);
This method does not add an item to the stack, it replaces the current matrix with the product of the current matrix and the given matrix.
