Detailed Description

A subclass of KSPlanetBase for seven of the major planets in the solar system (Earth and Pluto have their own specialized classes derived from KSPlanetBase).

Note

The Sun is subclassed from KSPlanet.

KSPlanet contains internal classes to manage the computations of a planet's position. The position is computed as a series of sinusoidal sums, similar to a Fourier transform. See "Astronomical Algorithms" by Jean Meeus or the file README.planetmath for details.

Provides necessary information about objects in the solar system.

Constructor & Destructor Documentation

KSPlanet() [1/2]

KSPlanet::KSPlanet ( const QString & s = "unnamed", const QString & image_file = QString(), const QColor & c = Qt::white, double pSize = 0 )

explicit

Constructor.

Parameters

s	Name of planet
image_file	filename of the planet's image
c	the color for the planet
pSize	physical diameter of the planet, in km

Definition at line 114 of file ksplanet.cpp.

KSPlanet() [2/2]

KSPlanet::KSPlanet ( int n )

explicit

Simplified constructor.

Parameters

n	identifier of the planet to be created

Member Function Documentation

calcEcliptic()

void KSPlanet::calcEcliptic ( double jm, EclipticPosition & ret ) const

virtual

Calculate the ecliptic longitude and latitude of the planet for the given date (expressed in Julian Millenia since J2000).

A reference to the ecliptic coordinates is returned as the second object.

Parameters

jm	Julian Millenia (=jd/1000)
ret	The ecliptic coordinates are returned by reference through this argument.

Definition at line 192 of file ksplanet.cpp.

clone()

KSPlanet * KSPlanet::clone ( ) const

overridevirtual

Create copy of object.

This method is virtual copy constructor. It allows for safe copying of objects. In other words, KSPlanet object stored in SkyObject pointer will be copied as KSPlanet.

Each subclass of SkyObject MUST implement clone method. There is no checking to ensure this, though.

Returns

pointer to newly allocated object. Caller takes full responsibility for deallocating it.

Reimplemented from SkyObject.

Reimplemented in KSSun.

Definition at line 150 of file ksplanet.cpp.

findGeocentricPosition()

bool KSPlanet::findGeocentricPosition ( const KSNumbers * num, const KSPlanetBase * Earth = nullptr )

overrideprotectedvirtual

Calculate the geocentric RA, Dec coordinates of the Planet.

Note

reimplemented from KSPlanetBase

Parameters

num	pointer to object with time-dependent values for the desired date
Earth	pointer to the planet Earth (needed to calculate geocentric coords)

Returns

true if position was successfully calculated.

Implements KSPlanetBase.

Reimplemented in KSSun.

Definition at line 265 of file ksplanet.cpp.

getUID()

SkyObject::UID KSPlanet::getUID ( ) const

overridevirtual

Return UID for object.

This method should be reimplemented in all concrete subclasses. Implementation for SkyObject just returns invalidUID. It's required SkyObject is not an abstract class.

Reimplemented from SkyObject.

Reimplemented in KSSun.

Definition at line 402 of file ksplanet.cpp.

loadData()

bool KSPlanet::loadData ( )

overridevirtual

Preload the data used by findPosition.

Implements KSPlanetBase.

Reimplemented in KSSun.

Definition at line 186 of file ksplanet.cpp.

untranslatedName()

QString KSPlanet::untranslatedName

(

)

const

return the untranslated name This is a dirty way to solve a lot of localization-related trouble for the KDE 4.2 release TODO: Change the whole architecture for names later
