I tried to change the smoke based on the feedback I've gotten and using
the images posted by TinCanMan as reference. I hope it's an improvement
over the last version.
This one also took quite a bit longer to render. On my Athlon 1700 it
took a little over 3 hours. But I still think it would have taken at
least five times as long to get a similar effect using media.
Comments much appreciated as always. :)

I think it is a vast improvement! Very nice.
Except the first second, there it looks like a transparent cone... maybe
fade it in slower?

Absolutely fantastic. And since you never see smoke "just starting" in most
situations, you can easily avoid that first few frames being too uniform. Just
have it "run ahead" a few frames in any animation you do.

Well, I don't know about the first few frames but the rest looks
excellent.
If it isn't realistic it sure looks like it (you could at least
fool me).
I'm curious about what you0re going to use it for.

Something about that looks very realistic. I still think that the turbulence
should start a little earlier.
The most unrealistic thing is probably easy to change: in the beginning of
the animation, where the smoke is just starting to appear, the top of the
smoke has a defined horizontal line. You should try fading it in, so the
flat top of the smoke has full transparency, and we can't really tell where
it has started.
You might also try adding a cigarette, and maybe an ashtray =)

Hi Rune,
That looks great! Very realistic. It dissipates
nicely, but it seems to have an abrupt start. It
might seem a little thick for a cigarette, but
I'm sure you can adjust it to suit the needs. Maybe
the color could be a little more blue. Too bad about
the render time, but it's going to be worth it.

Yes definitely. I really like the way the smoke tendrils move toward the top.
They have that lazy drifting quality about them.

oooh! I like.
looks tons better now.
there's still something that I can't pick out that makes it seem CG and not
RL, but isn't that the same with all CG.
Good work. I'm glad I could help out.

looks much better than the last, however i think you shoud make it thinner
at the base, and fatter at the top :)

Everyone gives praise here, and it's well deserved for the technical effort,
but let me add a tiny bit of poison.. On my monitor, when I turn up the
brightness it's very visible that the bezier patches still curls in
sometimes fast, abrupt and unexpected ways.. This is more visible now than
test 1 & 2 and those turns doesn't look like smoke.. Apart from that, it's a
very good imitation of the pictures posted for reference.. Very good.
Regards,
Hugo

Good!
Maybe a tad less granularity in the thick smoke, very visible in the
frames about 9 sec. into the animation.

I don't know about that. Changing that part now could mess up
everything... ;)

The comment of the thread - yeah I'll fix that. :)

Will do!

I think I'd rather fade it in as others suggest.

My particle system is far too simple to realistically simulate smoke, so
my goal is to just make it look realistic...
> I'm curious about what you're going to use it for.
I have no plans to use it in a longer animation. If I can clean up the
code enough I'll include it as a demo scene for my particle system.
Maybe you meant what object to use it for - well, I think I'll add a
cigarette and an ashtray after all.

Yes, the abrupt start. I'll have to fix that.

Doesn't that depend on the size of the cigarette? ;)

Oh, I thought I had made it very blue. I think I like the color as it is
now.

And if used in a larger scene, the smoke probably won't take up that
much of the screen space, so in real uses it might be faster.

Well, I never expected that I could make it totally believable. "Almost"
is good enough for me.

Thinner at the base maybe, but fatter at the top will increase render
time too much I think... :)

You're right, maybe a tad less granularily...

Fine by me. :)

Yes, I can see that. It's a result of how turbulence works in POV-Ray,
which I use though the vturbulence macro. Turbulence has some abrupt
changes some places.
Unfortunately I don't have any ideas for how to avoid it, but I'll keep
trying to find one.

Hrm. Watching one of mine now. because 've got so many fans in my computer,
the turbulance starts almost as son as the smoke particles leave the embers

atching mine now. I think the smoke becomes blue when you exhale?

Hope so. I've only just managed to get to 1200MHz (from last year's 400)

I was comparing your animation with the pics that TinCanMan
posted. The pics were quite a bit more blue, but they were
on a total black background.
And it still looks incredible!
