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.

Member Function Documentation

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.

Definition at line 72 of file Atmosphere.hpp.

float Atmosphere::getFadeDuration ( )

inline

Get fade in/out duration in seconds.

Definition at line 54 of file Atmosphere.hpp.

bool Atmosphere::getFlagShow ( ) const

inline

Get whether atmosphere is displayed.

Definition at line 59 of file Atmosphere.hpp.

float Atmosphere::getLightPollutionLuminance ( ) const

inline

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

Definition at line 77 of file Atmosphere.hpp.

float Atmosphere::getRealDisplayIntensityFactor ( ) const

inline

Get the actual atmosphere intensity due to eclipses + fader.

Returns

the display intensity ranging from 0 to 1

Definition at line 63 of file Atmosphere.hpp.

void Atmosphere::setFadeDuration ( float  duration )

inline

Set fade in/out duration in seconds.

Definition at line 52 of file Atmosphere.hpp.

void Atmosphere::setFlagShow ( bool  b )

inline
