class
OrbitCamera
(*args, **kwargs)¶ Bases:
cocos.actions.camera_actions.Camera3DAction
Orbits the camera around the center of the screen using spherical coordinates
-
get_spherical_coords
()¶ returns the spherical coordinates from a cartesian coordinates
using this formula:
Return type: (radius, zenith, azimuth)
-
init
(radius=None, delta_radius=0, angle_z=None, delta_z=0, angle_x=None, delta_x=0, *args, **kw)¶ Initialize the camera with spherical coordinates
Parameters: - radius : float
Radius of the orbit. Default: current radius
- delta_radius : float
Delta movement of the radius. Default: 0
- angle_z : float
The zenith angle of the spherical coordinate in degrees. Default: current
- delta_z : float
Relative movement of the zenith angle. Default: 0
- angle_x : float
The azimuth angle of the spherical coordinate in degrees. Default: 0
- delta_x : float
Relative movement of the azimuth angle. Default: 0
