Some information on background should go here
Set the scene background to a constant color. Any ray that fails to strike an object
will be set to the background color.
<background type="constant" name="name">
<color r="128" g="128" b="128" />
</background> |

- color: rgb
- The background color setting.
Creates a simulated sky background, along with an optional sun. This feature
does NOT add shadows to your scene, it is only a background feature.
Note that I have been unsuccessful in getting the "sun" object to appear
properly. Turbidity and power seem to have zero effect on the scene.
<background type="sunsky" name="backg" turbidity="4" add_sun="yes" sun_power="4">
<from x="5" y="5" z="2" />
</background>

- turbidity:
- Turbidity controls atmosphere density. 4 is an almost clear sky. The turbidity parameter affects how light is scattered in the
atmosphere, you should see it as sort of controlling the density of particles in the atmosphere. The higher the number, the
more particles.
- add_sun: yes|no
- Places a sun in from parameter's position
- from: xyz
- Location of the sun
- sun_power:
- How strong the sun is.
