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.
