Hi, ?

 

Simply set the fog-color to a darker color?

hi,

I don’t change the color to make it dark
I want to express that it darkens naturally as time passes by the influence of light.

Hi,

 

As there is no concept of day/night in OSG you need to adapt the color based on the time passed (you can use the osg-time for this or use a separate timer) .

Simply adapt the fog-color during the update-traversal.

 

Cheers

Sebastian

hi, Sebastian

Is fog operating independently of light?

Cheers.

osg::Fog has a colour value that you set with fog->setColor(Vec4(r,g,b,a));

Hi,

 

Yes, in FFP they don’t interact. If you want some Light+Fog interaction you need to write a shader.

Fog is simply a color “added” with respect to the distance from the viewpoint

 

Cheers

Sebastian
