Fractals are basically mathematical calculations which give birth to some stunning random images and formations. Fractal Domains (formerly known as FracPPC) is a program that
generates color fractal images which allows you to explore and create an unlimited variety of images.
With Fractal Domains you can generate color images of the most popular fractal, (known as the Mandelbrot set) and also generate images of what are known as associated Julia sets. You can also generate an unlimited variety of fractal types based on rational functions, including fractals based on Newton's method and Halley's method.
Although Fractal Domains isn't exactly straightforwards, it isn't too hard to get to grips with. It's essential though to read the developer tutorial before starting out. However, the tutorial is quite long and you'll need to set aside a few hours to really get the best from it. You should take a good look at the developer site in general which has a gallery of images created in Fractal Domains and also a handy list of FAQs.
Fractal Domains is a powerful fractal generating program if you're willing to invest time in learning how it works.
