IDirect3DRMFrame2::AddRotation
Adds a rotation about (rvX, rvY, rvZ) by the number of radians specified in rvTheta.
HRESULT AddRotation(
D3DRMCOMBINETYPE rctCombine,
D3DVALUE rvX,
D3DVALUE rvY,
D3DVALUE rvZ,
D3DVALUE rvTheta
);
Parameters
rctCombine
A member of the D3DRMCOMBINETYPE enumerated type that specifies how to combine the new rotation with any current frame transformation.
rvX, rvY, and rvZ
Axis about which to rotate.
rvTheta
Angle of rotation, in radians.
Return Values
Returns D3DRM_OK if successful, or an error otherwise. For a list of possible return codes, see Direct3D Retained-Mode Return Values.
Remarks
The specified rotation changes the matrix only for the frame identified by this IDirect3DRMFrame2 interface. This method changes the objects in the frame only once, unlike IDirect3DRMFrame2::SetRotation, which changes the matrix with every render tick.
