Hi,

I've recently started learning the intrinsics of fractal imagery and concentrated on iterated function system fractals. I have found a very fast way of generating such fractals in a paper called "Image based rendering of iterated function systems". I'm looking now for a database of initiators for the fractals, formulas that will produce interesting shapes and i can't seem to find one. The format i need the transformations to be (or a format that can be translated into this) is the following

a[i] b[i] c[i] d[i] e[i] f[i]

Where these coefficients represent an affine transformation: a[i] b[i] c[i] d[i] represents the rotational part(it's just a change of basis) and e[i] , f[i] represents the translation. So my questions are:

1. Where can i find such a suitable database?
2. How can i create new formulas and discover new shapes?

FractInt seems to use a format very similar to yours, except there is an extra column for the probability of picking a particular transform. They also support 3D IFS.

Thanks, alvaro. I already knew about that database and problem is, it's too small. I need more shapes to experiment with :).

It would have been nice to know what you already had, so we wouldn't waste our time while trying to help you.

Well, sorry about that. I have that database and the formulas from the paper: Image based rendering of iterated function systems(there are only a few there: only 4).
