How to create a smoke effect in iphone?

Question

i am developing an application where i want to do some smoke effect like animation and interact with that smoke.

Do i need to implement it OpenGLES or any simple solution?

Is there any sample application for it?

Answer 1

You could just write a simple particle emitter for that. Is it for a Game ? or for another kind of Application ?

It also depends on the level of realism that you're looking for. A guy got down voted for mentioning fluid dynamics, but if you really want realism, that's the best way to go.

Having said that, you can really get decent smoke using a regular particle emitter (you could even try to code it on Core Animation and not in OpenGL ES).

Also, if you're targeting iOS 5.0+, UIKit now includes several Particle FX that you could use, you just have to play with the parameters... checkout this tutorial

Answer 2

Yes, its possible with simple solution. You just need to use UIKit particle system. Have a look that sample https://github.com/lichtschlag/Dazzle, you just need to check fire and smoke sample.

Good luck
