Mandelbrot-Set Fractaler. GTK3+ based. Easy to use.

Fractal Renderer of the Mandelbrot-Set

What it is

XoiMandel is a simple and fast GUI based fractal rendering tool.

On startup it displays the main body of the Mandelbrot-Set. Navigation is easy and intuitive by using the mouse:

Zoom in or out:    Point + Scroll-Wheel
Move the fractal:  Point + Left-Click + Move
Change Resolution: Change Window Size

Prerequisites

$ sudo apt install build-essential
$ sudo apt install libgtk-3-dev

Getting Started

$ git clone https://github.com/johsteffens/beth
$ git clone https://github.com/johsteffens/xoimandel
$ cd xoimandel
$ make
$ ./bin/xoimandel

Changing the Color Model

The Renderer uses a predefined color model and histogram equalization. However, a given position can be stored into a file and later reloaded. That file is text-based and can be edited with a simple text editor. To change the color model, locate the entry 'color_map' and change one of the 9 associated values:

ra,rb,rc (for red)
ga,gb,gc (for green)
ba,bb,bc (for blue)

Save the file, reload it into XoiMandel and see what happens.

License

XoiMandel is licensed under GPLv3+.

A fractal picture you create using XoiMandel is not limited by that license. You may use, distribute or publish such pictures freely under your own terms.

Motivation

Except for creating a nice and easy-to-use tool for mathematical recreation, this application shall also demonstrate how to use the beth-framework and especially the programming language xoila.
