IDirectSound3DListener::GetOrientation

The IDirectSound3DListener::GetOrientation method retrieves the listener's current orientation in vectors: a front vector and a top vector.

HRESULT GetOrientation(
  LPD3DVECTOR lpvOrientFront,  
  LPD3DVECTOR lpvOrientTop  
);

Parameters

lpvOrientFront

Address of a D3DVECTOR structure that will contain the listener's front orientation vector.

lpvOrientTop

Address of a D3DVECTOR structure that will contain the listener's top orientation vector.

Return Values

If the method succeeds, the return value is DS_OK.

If the method fails, the return value may be DSERR_INVALIDPARAM.

Remarks

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).

The values returned are not necessarily the same as those set by using the IDirectSound3DListener::SetOrientation method. DirectSound adjusts orientation vectors so that they are at right angles and have a magnitude of less than or equal to 1.0.
