Spat5.viewer listener / speaker | microphone | phone orientation discrepancy

Spat
#1

listener orientation is always absolute (doesn’t depend of listener position) ;
But speaker / microphone / phone orientation is always relative to sweet spot / center.

/orientation/mode “fixed yaw” : doesn’t help, it just disable auto orientation of speaker when updating position. it doesn’t allow to set absolute orientation.

I need to display absolute speaker | microphone | phone orientation, as it works with listener orientation.

Am I missing smomething ?
is that expected behavior ?

thanks for your help :slight_smile:

Hello Mathieu,

Well, you can do that with the “/foo/direction/xyz [float][float][float]” which sets the direction axis (aka normal), expressed in world coordinates, for the object “foo”.
For any entity (listener, speaker, source, etc.), this uses absolute coordinates.
See spat5.viewer help patch, tab “orientation”.

Hope this helps,
T.

Thanks Thibaut

ho ok, so direction is absolute.

my objects orientation is expressed in quat… too bad a conversion is needed just to display orientation in viewer :frowning:
Any clue on how to convert a quat to direction ? :-s

Isn’t it a bit weird that orientation is absolute for listener, and relative for speakers, mics, … ?
