Microsoft DirectX 9.0

ID3DXMatrixStack::RotateAxis Method

Determines the product of the current matrix and the computed rotation matrix.


HRESULT RotateAxis(      

    CONST D3DXVECTOR3 *pV,     FLOAT Angle );


[in] Pointer to a D3DXVECTOR3 structure that identifies the axis angle.
[in] Angle of rotation, in radians. Angles are measured clockwise when looking along the rotation axis toward the origin.

Return Value

If the method succeeds, the return value is D3D_OK.

If the method fails, the return value can be D3DERR_INVALIDCALL.


This method right-multiplies the current matrix with the computed rotation matrix, counterclockwise about the given axis with the given angle (rotation is about the current world origin).

    D3DXMATRIX tmp;
    D3DXMatrixRotationAxis( &tmp, pV, angle );
    m_stack[m_currentPos] = m_stack[m_currentPos] * tmp;
