ID3DXMATRIXStack::MultMatrixLocal method (D3dx9math.h)

Note

The D3DX utility library is deprecated. We recommend that you use DirectXMath instead along with this header from GitHub.

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

Syntax

HRESULT MultMatrixLocal(
  [in] const D3DXMATRIX *pMat
);

pMat [in]

Type: const D3DXMATRIX*

Pointer to the D3DXMATRIX structure to be multiplied with the current matrix.

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

This method left-multiplies the given matrix to the current matrix (transformation is about the local origin of the object).

m_pstack[m_currentPos] = (*pMat) * m_pstack[m_currentPos];

This method does not add an item to the stack, it replaces the current matrix with the product of the given matrix and the current matrix.
