Method Details

init (self, a, f, name='')
(Constructor)

New Ellipsoid2.

Arguments:

a - Equatorial radius, semi-axis (meter).
f - Flattening: (float < 1.0, negative for prolate).
name - Optional, unique name (str).

Raises:

NameError - Ellipsoid with that name already exists.
ValueError - Invalid a or f.

Overrides: object.__init__

Note: abs(f) < EPS is forced to f=0, spherical. Negative f produces a prolate ellipsoid.
