Azimuth and elevation

The azimuth / elevation Coordinate System belongs to the class of spherical coordinate systems.

In this coordinate system, the 3D position of a point P is defined by 3 coordinates in the following way :
– Azimuth (from -180° to 180°).
– Elevation (from -180° to 180°).
– Radial Distance (in meters) – corresponds to the radius of the sphere on which P is lying (i.e., constant distance between Origin and P).

PTVR fonction to use:
Apply the set_azimuth_elevation_coordinates() fonction to the already created object "my_sphere" as below:

my_sphere = PTVR.Stimuli.Objects.Sphere ()   
...    
my_sphere.set_azimuth_elevation_coordinates (azimuth = 20, elevation = 135, radialDistance = 1)

😱 Warning: Note that the terms Azimuth and elevation have different meanings in different spherical systems.
