I would like to do an animation of cigarette smoke, preferrably using UIKit (and not, say, Cocos). I have worked with CAEmitterLayer before and gotten good results for various smoke and fog effects. Problem is, cigarette smoke looks nothing like the smoke from a fire. Using particles, I usually get something like this:

But what I am after is more like this:

Perhaps using particles isn't the best approach here?

  • Fluid dynamics us what would do this job. – Till Mar 08 '13 at 17:33

    I think it is more like fluid than particulate. Practically speaking, though, and sticking with UIKit, you might get an okay effect with a real good set of pngs set as UIImageView.animationImages. – danh Mar 08 '13 at 17:35
  • You might try repeating your request on the [Signal Processing SO site](http://dsp.stackexchange.com/), or maybe the [Physics SO site](http://physics.stackexchange.com/). May not get a "hit" but no real harm in trying. – Hot Licks Mar 08 '13 at 17:53
