I was playing around, making a new avatar for a forum, when I decided to go for a dynamic flame effect. It turned out to not be extremely difficult, so here it is. It doesn’t look perfect, but I think it’s good as far as procedural flame goes.

I’m not going to go into detail on how I made the effect, but it involves many calls to a very useful function that generates Perlin noise, and a handy bitmap operator that displaces a bitmap’s pixels by another bitmap’s. Combine this with an overlay that makes the flame dark in places, and tadaa: fire.
