Member Function Documentation

deinit()

void SpecificTimeMgr::deinit ( )

overridevirtual

Called before the module will be deleted, and before the OpenGL context is suppressed.

Deinitialize all OpenGL texture in this method.

Reimplemented from StelModule.

getEquinox()

double SpecificTimeMgr::getEquinox	(	int	year,
		SpecificTimeMgr::Equinox	equinox
	)

Compute the time of equinoxe for specific year Source: J.

Meeus "Astronomical Algorithms" (2nd ed., 1998) ch. 27

Parameters

year	(valid range: -1000..+3000)
equinox	type (Equinox::March or Equinox::September)

Returns

JDE or zero for outside the valid range

getSolstice()

double SpecificTimeMgr::getSolstice	(	int	year,
		SpecificTimeMgr::Solstice	solstice
	)

Compute the time of solstice for specific year Source: J.

Meeus "Astronomical Algorithms" (2nd ed., 1998) ch. 27

Parameters

year	(valid range: -1000..+3000)
solstice	type (Solstice::June or Solstice::December)

Returns

JDE or zero for outside the valid range

init()

void SpecificTimeMgr::init ( )

overridevirtual

Initialize itself.

If the initialization takes significant time, the progress should be displayed on the loading bar.

Implements StelModule.

for circumpolar objects, this sets to time of lower culmination

for permanently invisible objects, this sets to time of transit

previousRising

void SpecificTimeMgr::previousRising ( )

slot

Set simulation time to the time of previous rising of selected object (if applicable)

Note

for circumpolar objects, this sets to time of lower culmination

for permanently invisible objects, this sets to time of transit

previousSetting

void SpecificTimeMgr::previousSetting ( )

slot

Set simulation time to the time of previous setting of selected object (if applicable)

Note
