Simple Fog, Mist of Haze with "fog"

"fog" - Fog, Mist of Haze
without Interaction with Light
If we can do a scene without making visible of any light beams of sun light, lamps or spotlights
this is a good enough simulation of fog.
For fog with interaction with light we need to use "atmospheric media".
|
With ground fog.
|
Without fog: unreal clear horizon!
|
Constant Fog:
fog{ fog_type 1
distance 50
color White
}//----------------
|
At value of "distance" we will get 36% of the fog's color!
|
|
Ground Fog:
fog{ fog_type 2
distance 50
color White
fog_offset 0.1
fog_alt 1.5
turbulence 1.8
}//----------------
|
Below of "fog_offset": constant fog!
Height of the fog up to "fog_alt"!
|
|
Ground Fog:
fog{ fog_type 2
distance 5
color White
fog_offset 0.0
fog_alt 0.3
turbulence 1.8
}//----------------
|
Variation in distance and height!
|
|
A Font of fog:
fog{ fog_type 2
distance 5
color White
fog_offset -5.5
fog_alt 2.0
turbulence 1.8
up <-0.5,1,0>
}//----------------
|
"up <-0.5,1,0>" is vertical to the surface of the front of the fog!
