Member Function Documentation

void StelNavigator::addSiderealDay

(

)

[inline, slot]

Add one sidereal day to the simulation time.

The length of time depends on the current planetary body on which the observer is located.

void StelNavigator::addSiderealDays

(

double

d

)

[slot]

Add a number of sidereal days to the current simulation time, based on the observer body's rotational period.

Parameters:

d

the decimal number of sidereal days to add (use negative values to subtract)

void StelNavigator::addSiderealWeek

(

)

[inline, slot]

Add one sidereal week to the simulation time.

The length of time depends on the current planetary body on which the observer is located.

void StelNavigator::addSolarDays

(

double

d

)

[slot]

Add a number of Earth Solar days to the current simulation time.

Parameters:

d

the decimal number of days to add (use negative values to subtract)

double StelNavigator::getLocalSideralTime

(

)

const

Get the sideral time shifted by the observer longitude.

Returns:

the locale sideral time in radian

void StelNavigator::moveObserverTo	(	const StelLocation &	target,
		double	duration = 1.,
		double	durationIfPlanetChange = 1.
	)

Smoothly move the observer to the given location.

Parameters:

	target	the target location
	duration	direction of view move duration in s
	durationIfPlanetChange	direction of view + planet travel move duration in s. This is used only if the destination planet is different from the starting one.

void StelNavigator::moveObserverToSelected

(

)

[slot]

Move the observer to the selected object.

This will only do something if the selected object is of the correct type - i.e. a planet.

void StelNavigator::subtractSiderealDay

(

)

[inline, slot]

Subtract one sidereal week to the simulation time.

The length of time depends on the current planetary body on which the observer is located.

void StelNavigator::subtractSiderealWeek

(

)

[inline, slot]

Subtract one sidereal week to the simulation time.

The length of time depends on the current planetary body on which the observer is located.
