Detailed Description

Compute and display the daylight sky color using openGL.

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.

float Atmosphere::getAverageLuminance ( ) 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.
float Atmosphere::getFadeDuration ( )
inline

Get fade in/out duration in seconds.

bool Atmosphere::getFlagShow ( ) const
inline

Get whether atmosphere is displayed.

float Atmosphere::getLightPollutionLuminance ( ) const
inline

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

float Atmosphere::getRealDisplayIntensityFactor ( ) const
inline

Get the actual atmosphere intensity due to eclipses + fader.

Returns
the display intensity ranging from 0 to 1
void Atmosphere::setFadeDuration ( float  duration)
inline

Set fade in/out duration in seconds.

void Atmosphere::setFlagShow ( bool  b)
inline

Define whether to display atmosphere.

void Atmosphere::setLightPollutionLuminance ( float  f)
inline

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