Product Description:

TeraFractal lets you create and display fractal images that are based on an iterated function system. But rather than forcing you to define transformations numerically, TeraFractal represents each transformation as a rectangle in a control window. You make adjustments by simply manipulating these rectangles with the mouse to alter the translation, rotation, and scaling factors. This representation also allows you to see the properties of a given iterated function system at a glance. (See screen shot.)

TeraFractal updates the fractal image continually by using an efficient randomized algorithm that iteratively applies the transformations to a random starting point. This real-time feedback makes it possible to create lifelike fractals in a surprisingly short time.

What's new in this version:

Adds the ability to precisely control transformations using the arrow keys.
Fixes a display bug that affected the rendering of fractals that used rotation. TeraFractal rendering is now precisely mathematically correct. Most fractals created with earlier versions of TeraFractal will look different when viewed with this version.

Crashes on 10.4.11 when attempting to export a JPEG - Version: 2.1, 11/19/2007 07:10AM PST

All very impressive, until I try to export the fractal as a JPEG. This is the "default" fractal (seen when you open the app); hit "Cmd-P", tell it to export as "frac" in Documents (or any other filename/folder), hit "Export to JPG" and …

Seems like CoreGraphics isn't happy with what it's being asked to do. This is on 10.4.11 on a dual-core 2GHz MacBook.

I have been very interested in this particular kind of fractal and I find this application far easier to use that I thought possible. It does what it is suppose to and does it amazingly well. Its not a lot, but its very impressive.

A few additional features that would be nice would be the ability to enlarge the window, or render a high quality image at the selected settings or to reset the defaults (Standard Sierpinski's triangle) or let the user set it to one of the well known fractals it can make.
