                              Triaxial_

Unordered triaxial ellipsoid.

Triaxial ellipsoids with right-handed semi-axes a, b and c, oriented such that the large principal ellipse ab is the equator Z=0, beta=0, while the small principal ellipse ac is the prime meridian, plane Y=0, omega=0.

The four umbilic points, abs(omega) = abs(beta) = PI/2, lie on the middle principal ellipse bc in plane X=0, omega=PI/2.

Note: Geodetic lat- and longitudes are in degrees, geodetic phi and lambda are in radians, but ellipsoidal lat- and longitude beta and omega are in Radians by default (or in Degrees if converted).

Method Details

init (self, a_triaxial, b=None, c=None, **name)
(Constructor)

New unordered Triaxial_.

Arguments:

a_triaxial - Large, X semi-axis (scalar, conventionally in meter) or an other Triaxial, Triaxial_ or TriaxialB instance.
b - Middle, Y semi-axis (meter, same units as a), required if a_triaxial is scalar, ignored otherwise.
c - Small, Z semi-axis (meter, like b).
name - Optional name=NN (str).

Raises:

TriaxialError - Invalid semi-axis or -axes.

Overrides: object.__init__
