fract-ol

One of the first graphical projects at 42 school, fract-ol generates beautiful fractals from the complex numbers of an iterative mathematical construct. A fractal is a fragmented geometrical figure that infinitely repeats itself at smaller scales. This project uses the school's graphical library, MiniLibX.

Status

Finished: 22/04/2022.

Grade: 125%.

Usage

---

Note that this project was tested on Linux only. It may run on MacOS with small adjustments to the Makefile, as described in hsmits and jvan-sni's 42 Docs.

Installing and Compiling Fract-ol

Clone the repository, including the embedded MiniLibX repository:

git clone https://github.com/mcombeau/fract-ol.git && cd fract-ol && git submodule init && git submodule update

You will now be in the correct directory for compilation. Compile with make. Fract-ol should now be ready!

Executing Fract-ol

At execution time, you must specify a fractal to display. You may also provide other optional parameters:

./fractol <type> <options>

Types are :

• M, m, or 1: Mandelbrot fractal
• J, j, or 2: Julia fractal
• B, b, or 3: Burning Ship fractal
• T, t, or 4: Tricorn fractal
• X, x, or 5: Mandelbox fractal

For the Julia fractal set (and only this set), two additional parameters can be specified as calculation values. These represent a complex number that will change the shape of the Julia fractal. They must be fractional numbers between 2.0 and -2.0. For example:

./fractol J 0.285 -0.01

Additionally, you may specify a hexadecimal color for the fractal display:

./fractol M 00CCFF

Please note that for the Julia set, the color option will only be available after specifying calculation values:

./fractol J -0.4 0.6 65CD87

Fract-ol Controls

While Fractol is running, the following set of controls are available:

Controls	Action
W  A  S  D  or  ▲  ◄  ▼  ►	Move
- ,  +  or  scroll wheel	Zoom in and out
space	Change color scheme
left click	Shift Julia set [Julia only]
1 ,  2 ,  3 ,  4 , or  5	Switch fractals
esc  or close window	Quit fract-ol
