Detailed Description

Should be renamed as PlanetBasedObserver and derive from a more generical StelObserver class.

Definition at line 37 of file StelObserver.hpp.

Constructor & Destructor Documentation

StelObserver::StelObserver

(

const StelLocation &

loc

)

Create a new StelObserver instance which is at a fixed Location.

Member Function Documentation

Vec3d StelObserver::getCenterVsop87Pos

(

void

)

const

Get the position of the home planet center in the heliocentric VSOP87 frame in AU.

virtual const StelLocation& StelObserver::getCurrentLocation ( ) const

inlinevirtual

Get the informations on the current location.

Definition at line 63 of file StelObserver.hpp.

double StelObserver::getDistanceFromCenter

(

void

)

const

Get the distance between observer and home planet center in AU.

virtual StelObserver* StelObserver::getNextObserver ( ) const

inlinevirtual

Get the next observer to use once the life of this one is over.

Reimplemented in SpaceShipObserver.

Definition at line 73 of file StelObserver.hpp.

Mat4d StelObserver::getRotAltAzToEquatorial	(	double	JD,
		double	JDE
	)		const

returns rotation matrix for conversion of alt-azimuthal to equatorial coordinates For Earth we need JD(UT), for other planets JDE! To be general, just have both in here!

virtual bool StelObserver::isObserverLifeOver ( ) const

inlinevirtual

Get whether the life of this observer is over, and therefore that it should be changed to the next one provided by the getNextObserver() method.

Reimplemented in SpaceShipObserver.

Definition at line 67 of file StelObserver.hpp.

virtual bool StelObserver::isTraveling ( ) const

inlinevirtual

Get whether the location is a moving one.

Reimplemented in SpaceShipObserver.

Definition at line 70 of file StelObserver.hpp.

virtual bool StelObserver::update ( double  )

inlinevirtual

Update StelObserver info if needed.

Default implementation does nothing. returns whether we actually changed the position.

Reimplemented in SpaceShipObserver.

Definition at line 48 of file StelObserver.hpp.
