imap_processing.spice.geometry.spherical_to_cartesian(spherical_coords: ndarray[Any, dtype[_ScalarType_co]]) → ndarray[Any, dtype[_ScalarType_co]]#

Convert spherical coordinates to Cartesian coordinates.

Parameters:

spherical_coords (np.ndarray) –

A NumPy array with shape (n, 3), where each row contains the spherical coordinates (r, azimuth, elevation):

  • r : Distance of the point from the origin.

  • azimuth : angle in the xy-plane in radians [0, 2*pi].

  • elevation : angle from the z-axis in radians [-pi/2, pi/2].

Returns:

cartesian_coords – Cartesian coordinates.

Return type:

np.ndarray
