coords.Coords.cartesian_to_spherical

Coords.cartesian_to_spherical(dir=(0, 1, 2), angle_spec=0.017453292519943295)

Converts from cartesian to spherical coordinates.

Returns a Coords where the values are the coordinates of the input points in a spherical coordinate system. The three axes of the Coords then correspond to (theta, phi, r).

Parameters

dir: tuple of ints

A permutation of (0,1,2) specifying how the spherical coordinate system is oriented in the global axes. The last value is the axis of the system; the first two values are the equatorial plane; the first and last value define the meridional zero plane. Make sure to preserve the axes ordering in order to get a right-handed system.

angle_spec: float, at.DEG or RAD, optional

Multiplication factor for angle coordinates. The default (at.DEG) returns angles in degrees. Use RAD to return angles in radians.

Returns

Coords

The spherical coordinates of the input points.
