Detailed Description

Compute and display the daylight sky color.

The sky brightness is computed with the SkyBright class, the color with the SkyLight. Don't use this class directly but use it through the LandscapeMgr.

Member Function Documentation

void Atmosphere::computeColor	(	double	JD,
		Vec3d	_sunPos,
		Vec3d	moonPos,
		float	moonPhase,
		StelCore *	core,
		float	eclipseFac,
		float	latitude = 45.f,
		float	altitude = 200.f,
		float	temperature = 15.f,
		float	relativeHumidity = 40.f
	)

Called on every update to recompute colors of the atmosphere.

Must be called at least once after a call to draw(), as vertexGrid is lazily initialized at the first draw call.

float Atmosphere::getAverageLuminance ( void  ) const

inline

Get the average luminance of the atmosphere in cd/m2 If atmosphere is off, the luminance includes the background starlight + light pollution.

Otherwise it includes the atmosphere + background starlight + eclipse factor + light pollution.

Returns

the last computed average luminance of the atmosphere in cd/m2.

Definition at line 77 of file Atmosphere.hpp.

float Atmosphere::getFadeDuration ( )

inline

Get fade in/out duration in seconds.

Definition at line 59 of file Atmosphere.hpp.

bool Atmosphere::getFlagShow ( ) const

inline

Get whether atmosphere is displayed.

Definition at line 64 of file Atmosphere.hpp.

float Atmosphere::getLightPollutionLuminance ( ) const

inline

Get the light pollution luminance in cd/m^2.

Definition at line 82 of file Atmosphere.hpp.

float Atmosphere::getRealDisplayIntensityFactor ( void  ) const

inline

Get the actual atmosphere intensity due to eclipses + fader.

Returns

the display intensity ranging from 0 to 1

Definition at line 68 of file Atmosphere.hpp.

void Atmosphere::setFadeDuration ( float  duration )

inline

Set fade in/out duration in seconds.

Definition at line 57 of file Atmosphere.hpp.

void Atmosphere::setFlagShow ( bool  b )

inline

Define whether to display atmosphere.

Definition at line 62 of file Atmosphere.hpp.

void Atmosphere::setLightPollutionLuminance ( float  f )

inline

Set the light pollution luminance in cd/m^2.

Definition at line 80 of file Atmosphere.hpp.
