Project description

This project’s goal is to create a small fractal exploration program The constraints are as follows:

• Your software should offer the Julia set and the Mandelbrot set.

• The mouse wheel zooms in and out, almost infinitely (within the limits of the computer). This is the very principle of fractals.

• You must use at least a few colors to show the depth of each fractal. It’s even better if you hack away on psychedelic effects.

• A parameter is passed on the command line to define what type of fractal will be viewed. If no parameter is provided, or if the parameter is invalid, the program displays a list of available parameters and exits properly.

• More parameters must be used for fractal parameters or ignored.

• You must be able to create different Julia set with the parameters of the program.

As for the graphic representation:

• ESC will exit the program.

• The use of images of the minilibX is strongly recommended.

How to use

• The program works only on Mac OS. Linux version require some minor modifications
• Execute in the following way:

./fractol <set name: Mandelbrot, Julia, Ship> <number for color from 1 to 3> <number for c; from 1 to 3, works only for Julia Set>

• Move position with arrows, left and right mouse buttons
• Zome with - and = or mouse wheel
• For Julia Set it is possible to change value for c with q and w or a and s
• If you want to run more than 150 iteration, you should change the function for color (it is under comments inside fractol_utils.c)

Testing

The project was tested by myself and peers

Attempts

1st try: 123% (one peer found colors not good enough for max score)

Folders

srcs - source files

libft - libft with ft_printf

minilibx - minilibX library (already compiled)

include - header

pics - pics

Useful resources

• Tutorial on minilibX
• Another one
• And another one, but with more info about the project itself and useful links
• For better understanding on how to plot Mandelbrot set. Really useful
• Mandelbrot and Julia sets tutorial. Really handy, but with spolilers
• Just cool videos about Mandelbrot set: one and two
• Nice video about bit-shifting and colors

Tips

• Ask peers
• Learn maths and google
• Keep going
• Test (especially for colors)
• Rewrite
• Test
• Read about complex numbers. It is really important to understand them for this project. Here is a nice video, but in Russian. I am pretty sure there are nice videos in English as well
• Everything that goes after mlx-loop function is ignored
• It is possible to trace operation with the window by using mlx-hook. Read more here about X11 events and masks
• Julia and Burning ship are highly similar to Mandelbrot, so just some minor adjustments are required to get them
• The bigger is your max-iteration, more laggy is your program. I think 100-150 is the best number. Same for the window size
