IFSLab is an extremely easy way of creating beautiful and sophisticated IFS fractals.

Rather than having to deal with complicated math, you just define a simple master shape, clone it a few times, resize/remove/reposition the clones and watch in realtime how your IFS fractal develops.

Main Features:

  • Assistent for getting started quickly
  • High quality realtime preview
  • Extremely fast rendering
  • Easy-to-use graphical interface
  • Export to JPG, TIFF and QuickTime movie
  • Random fractal generation
  • Extensive documentation included
  • Makes full use of multiprocessor / more...

What's New

Version 2.0b2:
  • fixed an issue where network rendering in mixed networks (with PPC *and* Intel Core Macs) would fail
  • enabled the scroll wheel for rotating shapes


Mac OS X 10.4 or later

For more fractal-related software go to www.hypertextbook.com/chaos/92a.shtml. Perhaps also take a look at www.synthemesc.com/StrangeWorld/ or www.eudaemon.net/macfract/.

Not complaining because it is cool and free, but while the interface is fine, the image quality is lacking.

The 'brightness levels' slider seems to adjust between 'too grainy' and 'too dark' with the whole thing being dark and grainy all the time anyway.

Ok for quick exploration but there should be a slow/smooth high quality option too.
You should use more than just 256 gray levels, and maybe a curved gamma mode. Maybe randomization or oversampling or just more millions of iterations.

I would also very much like to see a "render at ____ x ____ resolution and save" command, to render fractals much larger than my current screen resolution.

Exporting high resolution TIFFs is coming up in the next release (ready by tomorrow, if all goes well).

The final version should also release a more sophisticated colouring model; I'll get working on that as soon as I'm back from the holidays ;-)

Many thanks for your input!

I've only been using this for a day, but it looks like 'all bugs have been fixed' with this update. IFS fractals have always been my favorite type of fractal, so I'm having a lot of fun playing with them :D
