[osg-users] I want to darken the osg::fog at night too, what should I do?

[OpenSceneGraph Users]

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

hi, Sebastian

 

Is fog operating independently of light?

 

Cheers.

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,

 

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, ?

 

Simply set the fog-color to a darker color?
