Hmm,
well there are a few parameters currently.
For the atmosphere,
There is a turbidity parameter (like in the previous sky model) that controls the amount of scattering due to larger droplets (amount of haze).
There is an asymmetry parameter for the Mie scattering approximation, and there's the characteristic height of the haze density curve.

For the clouds:
I'll probably do something like:
you can have an arbitrary number of layers, for each layer you can specify
* the start altitude
* end altitude
* a list of Perlin noise (frequency, amplitude) pairs
* overall noise bias; controls sparseness of clouds

Super sweet! :D
And the clouds stay the same in each randering!!! :D :D :P

Awesome!

:shock:

I missed the whole thread till here... I would not have thought you would implement such cool stuff that fast (volume emiters, 3d noise and such).

Anything else I want ? Ok, clouds as blend maps for materials :D

Fantastic Ono !

Really nice. How did you create the clouds? Which parameters can you control?
Are you planning to make random clouds just by choosing different types of clouds (cumulus, cirrus etc.)?
Or are you just implementing the effects on clouds and the shape of the clouds is created via 3d-modelling or particles?

Wow! Indigo is well on its way to PWN Maxwell and Fryrender :D Imagine that: Indigo, Unbiased Procedural Renderer :shock:

Ono you are a god :!:

That's GREAT!
I had some troubles with this site, the lsat few days, so I wasn't able, to see this any earlier.
it already looks quite real!
What about pinkish clouds at blueviolettish-darkergetting sky and sunset sun + clouds? those still are missing in your tests :D

simply GREAT!
Could you also make kinda procedual rain -> rainbow, that's more realistic than your test, with manitwos scene?
