Colatitude angle usage 360 degree(colatitude <= np.pi and colatitude >= 0) #298

ClearVoiceM commented 1 year ago

Hi, I'm trying to generate audio 360 degree azimuth and elevation. But pyroomacoustics can support max 180 deg elevation. Is there any way to change elevation(colatitude) angle to support 360 degree. example: dir_obj = CardioidFamily(orientation=DirectionVector(azimuth=-90, colatitude=-90, degrees=True), pattern_enum=DirectivityPattern.HYPERCARDIOID)

Thanks

Hi, sorry for poor response time. Spherical coordinates are defined with azimuth in [0, 360] and colatitude from 0 to 180 degrees (0 being the north pole). This is similar to latitude and longitude on the globe. The ranges are sufficient to describe every point in a non-redundant way. https://en.wikipedia.org/wiki/Spherical_coordinate_system

Hi, Thanks for the answer.
