Title: Tips 'n' Tricks on dIFS anyone?
Post by: Madman on March 15, 2012, 10:18:47 PM
Now and then I accidentally stumble accross some interesting composition in dIFS, but I'm somewhat lost in what I'm doing. Main issues:

  • How do formula's influence one another in hybrids? It seems that formula 1 influences formula 4, but also vice versa...
  • How do I get rid of noise? See parameter file below. If anyone can make this noiseless without loss of composition, please post the improved parameters...

I had a third question but I forgot  :-\

Anyway, here are the parameters mentioned in bullet 2.

I don't know man, I don't think I have never done a d.IFS hybrid with more than 1 iterations per Formula. I rember reading here somewhere that d.IFS formulas didn't need more than 1 iteratiom per, I could be wrong but that stuck in my head for some reason and I stuck to it. As for how they interact with each other I wish the hell I knew because they's touchy as hell.

Okay, can I upload some on the main section? :beer: (... i UPLOADED now http://www.fractalforums.com/index.php?action=downloads;sa=view;down=37 ) :embarrass:

Thanks so much, DB! I'm a lot less confused now. I also completely missed the tutorial section for M3D. Must have been because I was down under and too busy with non-FF stuff when this topic developed...  :embarrass:

Ah, well, there still is the issue of getting the noise out of the parameter set I posted. I tried the stuff mentioned in the tutorials, but either the composition changes or the noise doesn't disappear. So, uhh, anyone up for the challenge?  :dink:

And, somewhat off topic, and mainly addressed to Jesse, I guess... Might it be an idea to make one tab for shapes and one for transforms in dIFS in a next version?

What DIFS stands for? Distance Estimated Iterated Function System?


Title: Re: Tips 'n' Tricks on dIFS anyone?
Post by: Jesse on March 28, 2012, 07:17:51 PM
Thought of something like direct distance iterated function (primitives) system... DIPS would also fit  :dink:

Thanks. Google gave me a Distributed Inter-Frame Space, Defense Integrated Financial System and so on, throught I can imagine that soon it will give tons of pictures ;)
