visu3d.math.carthesian_to_spherical(point3d: etils.enp.array_types.typing.FloatArray, *, xnp: Any = Ellipsis) → visu3d.math.coord_utils._SphericalCoords[source]#

Convert (x, y, z) to (r, theta, phi).

Follow https://mathworld.wolfram.com/SphericalCoordinates.html conventions.

Parameters:

  • point3d – 3d carthesian coordinates

  • xnp – Numpy module

Returns:

radial theta: azimuth / longitude in range (0, tau) elevation: polar / elevation / colatitude in range (0, tau/2)

Return type:

r
