Galaxy | SuperCollider 3.13.0 Help

Description

A representation of our galaxy, a.k.a. The Milky Way. It is intended as a placeholder for astronomic information.

A small query system is implemented for handling astronomic elements information.

At the moment, only information about exoplanets is supported.

Get exoplanets information in CSV from here: http://exoplanet.eu/catalog/

Class Methods

.new

Create a galaxy and load its information

Arguments:

filePath	Path to a csv file containing the desired data
type	A `\Symbol` with the kind of data to load. At the moment, only `\exoplanet` is supported

Instance Methods

.getExoplanetsBetween

Get a List of all exoplanet names located in the desired distance range,

Arguments:

min
max

.getExoplanetsAround

Get a List with the n exoplanets closer to dist

Arguments:

dist
n

.exoplanets

Get a Dictionary in the form (exoplanetName -> exoplanetInstance)

.getExoplanetsWithComposition

Get a List with all exoplanet names in which different molecules have been found
