IDirectSound3DListener8::GetOrientation

The GetOrientation method retrieves the orientation of the listener's head.

HRESULT GetOrientation(
  D3DVECTOR * pvOrientFront,
   D3DVECTOR * pvOrientTop
);

Parameters

pvOrientFront

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

pvOrientTop

Address of a D3DVECTOR structure that receives 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 up from 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 SetOrientation. DirectSound normalizes orientation vectors so that they are at right angles and have a magnitude of less than or equal to 1.0.

Requirements

Header: Declared in Dsound.h.

Import Library: Use Dsound3d.dll.
