📜 About Project

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.

For detailed information, refer to the subject of this project.

🚀 TLDR: The fract-ol project is one of the three "beginner" graphical projects of the 
	 cursus. It teaches you about using graphic library, advanced math, and more.

Note

Because of 42 School norm requirements:

• Each function can't have more than 25 lines of code.
• All variables are declared and aligned at the top of each function.
• Project should be created just with allowed functions otherwise it's cheating.

📑 Fractals List

The program supports these fractal sets:

Name	Formula
Mandelbrot	$z_{n+1} = z_n^2 + c, z_0 = 0$
Julia	$z_{n+1} = z_n^2 + c, z_0 = c$
Burning Ship	$z_{n+1} = abs(z_n^2) + c, z_0 = 0$
Tricorn	$z_{n+1} = \frac{}{z_n}^2 + c, z_0 = 0$
Mandelbox	It's more complex, see this article
Celtic Mandelbar	$z_{n+1} = \frac{}{z_n}^2 + c, z_0 = c$

🎮 Controls

The program supports the following controls:

Key	Description
ESC	Close the program window
Keys [1-6]	Move to another fractal
Keys [Q-Y]	Change the color of fractal
Keys [A-H]	Change the color of fractal
Mouse Scroll	Zoom in and out of the fractal
⬆️ ⬇️ ⬅️ ➡️	Change the viewpoint
Key L	Lock Julia's fractal
Zero	Reset the fractal to its initial state

👨‍💻 Usage

Requirements

The program is written in C language and thus needs the gcc compiler and some standard C libraries to run.

Instructions

1. Compiling the program

To compile the program, run:

$ cd path/to/fractol && make

2. How to run the program

Run the executable too see the help message:

./fractol

Or run with some supported fractal:

./fractol mandelbrot
