Scattering Object Media

Sun light shining in a room.
Local haze by scattering media:
( scattering = diffuse radiating of light )
For a local light scattering atmospheric medium
to generate fog or haze inside of a room, we use "media" with
with a restricting container:
|
|
The room filled with haze:
box{
<0,0,0>, <R_x, R_y, R_z>
pigment { rgbt 1 } // clear
hollow
interior{
media{
scattering{ 1, 0.17 extinction 0.01}
samples 10, 20 // min, max
} // end media
} // end interior
} // end box
//----------------------------------------
|
This still looks very rough!
We can see the layers of each individual "sample"!

Scattering media box filling the room with haze:
box{
<0,0,0>, <R_x, R_y, R_z>
pigment { rgbt 1 } // clear
hollow
interior{
media{
scattering{ 1, 0.17 extinction 0.01}
samples 100, 500 // min, max
} // end media
} // end interior
} // end box
//----------------------------------------

With increased number of samples:

Last but not least adding a door:
