Title: Guess what fractal is it Post by: flexiverse on February 13, 2012, 10:24:40 PM Hey man,
I was wondering if anyone can help me. Can you tell me what kind of fractal can produces this? (http://www.haniff.co.uk/images/what_is_this_fractal.jpg) anything close to it will do ! I was thinking playing with some IFS transformations based on the star shapes would create it? Also, I think it is a 3D fractal not 2D though....

I usually see structures like this when I test a 3D engine.
I've attached two examples, one made in Structure Synth (made of polygons) and one distance estimated in Fragmentarium.

Surely these aren't self similar fractals though? Could reverse engineering in a fractal compression / ifs way lead to fractal equations that can make this? I.m looking for a formula and fractal type you see.... Title: Re: Guess what fractal is it Post by: Tglad on February 23, 2012, 08:05:38 AM I think Syntopia is spot on, another way to think of this is as a 2d plane, and each pixel you shade based on the number of 'divisors' of the pixel. For example: pixel (4,2) is shaded dark as it only has two divisors (2,1) and (4,2), but pixel (24, 6) is lighter as it has four divisors (4,1), (8,2), (12,3), (24,6). It is probably a fractal because if you scale it by any integer and you get the same result, only lighter or darker. It probably doesn't convert into an IFS, since IFSs are a very narrow subset of all fractals. |
