The IDirectSound3DListener::SetOrientation method sets the listener's current orientation in terms of two vectors: a front vector and a top vector.
HRESULT SetOrientation(
D3DVALUE xFront,
D3DVALUE yFront,
D3DVALUE zFront,
D3DVALUE xTop,
D3DVALUE yTop,
D3DVALUE zTop,
DWORD dwApply
);
DS3D_DEFERRED | Settings are not applied until the application calls the IDirectSound3DListener::CommitDeferredSettings method. This allows the application to change several settings and generate a single recalculation. |
DS3D_IMMEDIATE | Settings are applied immediately, causing the system to recalculate the 3-D coordinates for all 3-D sound buffers. |
If the method succeeds, the return value is DS_OK.
If the method fails, the return value may be DSERR_INVALIDPARAM.
The front vector points in the direction of the listener's nose, and the top vector points out the top of the listener's head. By default, the front vector is (0,0,1.0) and the top vector is (0,1.0,0).
