Mixer-plugin 3D positioning and listener's orientation

Question

HI AK developers,

For in_pInputContext->Get3DPosition's AKEmiiterAndListenerPair with positioning set to 3D with user-defined source objects, does the azimuth and elevation functions between object and listener correctly account for BOTH the azimuth and elevation of the orientation of the listener? I'm using 2014 beta 1 fyi.

Thanks!

Answer 1

Hi Yuancheng,

They do. Listeners are defined on the sound engine API with 3 vectors expressed in cartesian coordinates: position, direction front and direction top. Azimuth and elevation of an emiter-listener pair are derived from all these vectors, plus the vector (also in cartesian coordinates) describing the game object position.

Xavier.
