9 Best Free Linux Fractal Tools

A fractal is a geometric shape or quantity which displays self-similarity and non-integer dimension. The property of self-similarity applies where a self-similar object is exactly or approximately similar to a part of itself. If you zoom in on any part of a fractal, you find the same amount of detail as before. It does not simplify.

There are many mathematical structures that are fractals including the Koch snowflake, Peano curve, Sierpinski triangle, Lorenz attractor, and the Mandelbrot set. Fractals also describe many real-world objects, such as crystals, mountain ranges, clouds, river networks, blood vessels, turbulence, and coastlines, that do not correspond to simple geometric shapes.

Fractals are rooted in chaos theory, and because of their nature they are perfect for organic looking artwork and landscapes.

Fractal-generating software is any computer program that generates images of fractals. Linux has a great selection of fractal software to choose from.

To provide an insight into the quality of software that is available, we have compiled a list of 9 absorbing fractal tools. Hopefully, there will be something of interest here for anyone who wants to create their own unique images from computer generated art.

The chart below ranks them.


Now, let’s explore the 9 fractal tools at hand. For each title we have compiled its own portal page, a full description with an in-depth analysis of its features, screenshots, together with links to relevant resources.

  1. Hi Steve, What produced the image at the top of this article? Im after something that will “animate” create semi random movement, ie swirling of this sort of image/ongoing transformation.

    1. I had this exact some thought.

      I used to use a program, around 2006, that produced these kind of images but I cannot, for the life of me, remember the name. The style is really distinctive. . .

      I think it wasn’t entirely fractal based, but there were a lot of parameters, and it made these beautiful, wispy images,

      I’m almost certain that image at the top comes from this program.I’m almost certain I would remember the name if I saw it, and I don’t think it’s any of the ones listed.
