Seems like we'd been waiting for some fractals since 2007 or so, good work.

Great achievement! 
Congratulations and THANK YOU very much! "From the moment we are born, we start being filtered..." |

Nice! Finally some new scripters in the community 
It is a very nice smoothing formula you added there. I experimented with that too, but I'm not sure I got it as smooth as this one.
One minor thing - you can return the iterationCount variable as 5th parameter. This is for anti-alias hinting, which should speed up the anti-aliasing pass considerately. |

Thats for sure..  I am still on Hello World... 
Good stuff jitspoe...I'll have to play with it.. Stupid things happen to computers for stupid reasons at stupid times!

cool, jitspoe! If wishes were horses... there'd be a whole lot of horse crap to clean up!

Really wonderful, jitspoe! Fractals are so amazing aren't they? |

I imagined this filter being hugely complex and upon opening it I was shocked, shocked I tell you, of it's simplicity. Shows you how little I understand the magical world of mathematics. Great job!

I've always wanted to play around with fractals, and somehow managed to never get around to it until now. When I discovered that Filter Forge added scripting, I had to try it out. I was surprised to search the filters and not find a Mandelbrot set filter (though later I discovered there was a Mandelbrot example after submitting the filter).
I did a search for "Mandelbrot equation" and found that it was quite simple: z = z^2 + c. Well, almost that simple. C is a complex number. I've forgotten most of the stuff I learned in college, so I just searched for some source code examples in C/C++, and they were pretty easy to adapt to Lua (never used Lua before, either). The most difficult part was the smoothing (just noticed there's a bug in there that I need to fix, but you only see it on the far outside edges). I couldn't find a very clear explanation for it, but I figured it out eventually.
Now I wonder what other kinds of cool images can be generated with simple equations...

Thanks for the explanation, jitspoe!
Sphinx, that's some really great stuff. The latter samples of the second link are pretty wild!
Both of you inspire me to experiment with fractals. I thank you!
