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

(

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.

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

(

void

)

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.
