            SCircle

A spherical circle from pgSphere.

The constructor accepts an SPoint center and a radius in rad.

Instance Methods

__init__(self, center, radius)
x.__init__(...) initializes x; see help(type(x)) for signature

source code

asDALI(self)
returns the "DALI-form" for this circle.

Inherited from PgSAdapter: __eq__, __ne__, __repr__, asSODA

Inherited from object: __delattr__, __format__, __getattribute__, __hash__, __new__, __reduce__, __reduce_ex__, __setattr__, __sizeof__, __str__, __subclasshook__

Class Methods

fromDALI(cls, daliSeq)
returns a circle from its DALI float sequence.

Method Details

init(self, center, radius)
(Constructor)

source code

x.__init__(...) initializes x; see help(type(x)) for signature

Overrides: object.__init__: (inherited documentation)

asDALI(self)

source code

returns the "DALI-form" for this circle.

This is an array containing the center coordinates and the radius in degrees.

fromDALI(cls, daliSeq)
Class Method

source code

returns a circle from its DALI float sequence.

Any None in daliSeq makes this a None to help with VOTable null value handling.

asPoly(self, nSegments=32)

Overrides: PgSAdapter.asPoly
