The DirectSound3DListener.SetOrientation method sets the listener's orientation in terms of a front vector and a top vector.
object.SetOrientation(xFront As Single, _ yFront As Single, _ zFront As Single, _ xTop As Single, _ yTop As Single, _ zTop As Single, _ applyFlag As CONST_DS3DAPPLYFLAGS)
If the method fails, an error is raised and Err.Number may be set to DSERR_INVALIDPARAM.
The front vector points in the direction of the listener's nose, and the top vector points in the direction of 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 top vector must be at right angles to the front vector. If necessary, DirectSound adjusts the front vector after setting the top vector.
