import pyproj



def reproject(record, semi_major, semi_minor, source_proj, dest_proj, **kwargs):

    """

    Thin wrapper around PyProj's Transform() function to transform 1 or more three-dimensional

    point from one coordinate system to another. If converting between Cartesian

    body-centered body-fixed (BCBF) coordinates and Longitude/Latitude/Altitude coordinates,

    the values input for semi-major and semi-minor axes determine whether latitudes are

    planetographic or planetocentric and determine the shape of the datum for altitudes.

    If semi_major == semi_minor, then latitudes are interpreted/created as planetocentric

    and altitudes are interpreted/created as referenced to a spherical datum.

    If semi_major != semi_minor, then latitudes are interpreted/created as planetographic

    and altitudes are interpreted/created as referenced to an ellipsoidal datum.



    Parameters

    ----------

    record : object

          Pandas series object



    semi_major : float

              Radius from the center of the body to the equater



    semi_minor : float

              Radius from the pole to the center of mass



    source_proj : str

                      Pyproj string that defines a projection space ie. 'geocent'



    dest_proj : str

                   Pyproj string that defines a project space ie. 'latlon'



    Returns

    -------

    : list

    Transformed coordinates as y, x, z



    """

    source_pyproj = pyproj.Proj(proj = source_proj, a = semi_major, b = semi_minor)

    dest_pyproj = pyproj.Proj(proj = dest_proj, a = semi_major, b = semi_minor)



    y, x, z = pyproj.transform(source_pyproj, dest_pyproj, record[0], record[1], record[2], **kwargs)
