Editors' Review


GNU XaoS 3.5 is a free, open source fractal generator and "zoomer" that offers smooth, fluid navigational movement as you zoom in or out of a fractal. It includes 24 well-known fractal formulas with many possible variations in effects and appearance, but you can also use it to generate your own fractals. It offers effects like a starfield generator, embossing, motion blur, pseudo 3D mode, and even a text display.

The program's 32-bit installation executable includes the 64-bit version for recent editions of Windows like Vista and 7, both of which we used for testing. The simple, efficient, dialog-based interface opens with the iconic Mandelbrot set, the first-ever fractal, displayed in the main window. Mouse buttons control the zoom; left clicks zoom in; right clicks zoom out. There are no other controls as such, only file menus, including a Help file that offers animated tutorials explaining what fractals are, how the program works, and its many configuration options. These include menus for choosing fractals, setting their mathematical calculations, applying filters, and controlling the program's motion. However, the simplest and best way to get acquainted with Xaos is to click on a part of the fractal and start zooming in. If your mind isn't blown in seconds, give it time: Fractals are amazing, astounding, beautiful. and gigantic fun.

We've used fractal software for many years, and it's always been fun and fascinating, not to mention educational, even when it came on a floppy and ran in Windows 95. XaoS is a sure keeper.

"Excellent starter program when learning about fractals."

Tutorial is ok, filters are standard ones, able to enter your own formulas, colors - once you learn how to come up with the info needed. Fun to explore with when you've never done any kind of fractals before, helps you understand what all the different fractal terms mean. You can start creating fractals quickly with this program. Bonus: It's free.


The tutorial help was hard to adjust and use at times for me. Very simple but did help understand the very basics needed but not the more advanced stuff.


It's the second simple fractal program I've used. It's helped me create a basic fractal to use with my other paint tool program to add interesting starter point or background. Learning from it is helping me understand the more advanced Fractal programs much better while I'm learning them. Good Starter.

If you want to know more a bout fractals or explore various types of fractals even just at random, this is the tool to do it with


it has its limitations in memory usage and processor core usage, the next step would be to rebuild it on a more complex API like OpenGL so as to manage memory better, improve scalability, begin multithreading the program, and start using the compute power of new generation graphics cards ;)


in summary this program has SO MUCH potential, we all need to invest in this... at some point maybe, withenough processing power we can get to the point in which we can explore fractals in 3D... one day! :D

Easy to use
Can enter own formulae
Autopilot mode will zoom in or out of an image smoothly
The help explains about fractals and gives animated examples


Really can't think of any


Everything is provided, including mathematical explanations, to explore and learn to understand fractals. Well put together program with ample examples and tutorials.
