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.

This project has been archived in the state it was in at the time of evaluation.

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
