Perlin Noise Fire Effects

Hey there…

Would someone please explain to me the basics of how to use perlin noise and displacment filters to create those fancy fire effects. I can’t find any good source codes / tutorials on the net and my brain is aching… i cant seem to work it out!

Here is my favourite example of the fire - http://www.kaourantin.net/2005/08/little-old-school-fire-effect-using.html
Any light shed would be greatly appreciated! :hugegrin:
