It's better now. There are just some unnatural looking turns half way up,
but I think, if the smoke was part of a complex scene, no one would notice..
As others have said, it looks sort of, like a 2D paper that curls.

>> Nice to see your system moves to beta stage!  :o)
>You're welcome to help testing it if you want.

Yes please, I'd like to see how it actually works! Though I'm a newbie to
such things, and don't know if I can offer any useful feedback. But when my
spaceship / shuttle is finished, I'm going to need smoke from the engine,
and when it lands / take off, so your particle system will find good use,
for many people I think. :o)

As a smoker, I can say that this second animation looks very realistic.
True, a greater thinning and spreading out at the top would be even more
realistic, but its damn good now!

However, one little tweak:  (at least on my cigarettes) the smoke starts out
looking like straightened double-helix; thickness on either side and thinner
in the middle. I don't know if this is possible to do, but after looking
closely, that's what it looks like.  :)

Anyway, keep up the awesome work!

I don't know what the typical curly pattern looks like... :/

See the attached image. How many blocks can you make out?

The animation is designed to be viewed on a screen where 8 to 12 blocks
can be made out. If you can see more than that, your screen is too
bright, or I have designed the animation in a bad way. Just wondering if
that might be part of the cause when you say that the smoke doesn't
dissipate.

It spreads out a little. Anyway, I'm afraid I can't quite get rid of the
ribbon-like appearance completely, due to the way the smoke is made...

I hope you can find a picture to illustrate it! I too have been looking
for pictures of smoke in general, but it's surprizingly hard to find any
IMO.

But that's the opposite of what everyone else have been saying about the
last animation. :(

Have I gone from one extreme to the other in this regard?

> Also, It looks sort of 2D...

I know it looks a little ribbon-like. I'm trying to reduce that effect,
but it can't be avoided completely I'm afraid.

Good then. Any improvement is a good improvement. :)

I can see what you mean - I'll see if I can fix that.

I hope you're right. ;)

Yes, that's because that's what it actually is. I think smoke behaves a
little like that, so I choose to take that approach to the problem.
However, I'm doing my bet to hide the truth and make the 2d paper look
like real smoke...

> Yes please, I'd like to see how it actually works!

I'll send it to you.

Well, simply using it and telling me about your experience will be
helpful. :)

It does look like smoke in a quiet room, yes :)

And test 1 looks like smoke in a room with a little bit of air flow (open
window or door nearby)
