Hi all,
Here is the final version of my scene with cigarette smoke (see 
<news:3D4### [at] lepiorg>).
At first it should have been an irtc entry (you know how you get when 
you feel lonely, smoking and drinhing...), but I feel like it's 
definitively off topic.
The bottle is an old model I made years ago 
(http://juliengourdon.free.fr/images/kro.jpg, rendered with pov3.1), and 
improved a bit.
Someone spoke about making a scene with as many of POV-Ray's features as
possible, and I think we have here a good candidate :-)
The smoke is media with a function density; Red part of cigarette : two 
isosurfaces, one filled with red emitting media; There are photons but I 
can't really see where they came; Kind of a reflective blur on the 
ash-tray; area_light through the window; radiosity (with normal 
settings); And finally focal blur : twas the first time I used it in a 
scene, it seems that I missed something - I find it way too blurry.

Render time : 5 day and 1 hour on an athlon XP 2000+. Was it worth...?

Questions and comments are welcome !

    Very, nice, I don't think it's too blurry, however, I do have one
comment - there's no ash in the ashtray!

As a certified NON-SMOKER i can only hope you bring all those smokers to
ONLY smoke YOUR (virtual) cigarettes :-) so our health will benefit.

...I always like to see cigarette smoke.

But this smoke looks a little bit dense to me. And where are the ashes?
And if people are used to put the cigarettes directly on the table, there
should be
marks from the burning cigarettes on the table.
Some matches?
The bottles do not look as anybody had them ever in hand. Fingerprints?

I'm sorry to say this, but all in all it think it looks much too *clean*.

But the glooming cigarette is well done and I like to see it done with
POV-Ray.
Just to make clear that there are not only those intolerant, health
fanatic...
...ok, ok, I'll stop the flame.

I don't think it is off topic!

nice, but why it take so extreme long to render ?
I guess this is 'advantage' of focal blur ?
