Jux for Windows

Jux is a fractal explorer for 2D Julia and Mandelbrot sets. It includes a variety of formulas. It has beautiful coloring and lighting effects. It is easy to use. There is no formula editor or scripting.


The free version is limited to 640x480 anti-aliased rendering. Register to unlock the render size controls, enable batch rendering, allow exporting gradients in .ugr format, and support further development.

What's new in Jux v2.011

Note: if you are using Jux v1.x, it is recommended to uninstall it, then install Jux 2.0 to the same folder. Use the same location for personal data as before. The Sample files now have subfolders so you may need to remove the old ones from Samples to avoid duplication. Your own files should be kept separate from the Samples folder. If you are already using Jux v2, you can install this update without uninstalling.

If you already registered Jux, it is valid for v2.011 too: updating is free. If you lose your registration key, just email us.

Formulas and navigation

Jux can draw both Julia and Mandelbrot fractals.

Here are some examples of different formulas and coloring (without lighting).


There are many possible ways to color Julia fractals. Jux has built-in methods chosen for their simplicity, flexibility and aesthetics. You can use coloring alone, or modify it with heightfield lighting effects.


Jux can add lighting effects to bring the fractals into 3D. The fractal is calculated as a height field in a 3D lighting environment.

Here are some examples of lighting with various materials.
