Mandelbrot

Mandelbrot set in C

I kept original version, because is easy to understand how it works. It is kept in original/mandelbrot_original.c

Current version is optimized and have several advantages:

• faster,
• uses no array,
• is able to zoom
• have different coloring technics.

Build

To build everything, do

make

This will produce:

• mandelbrotcmd - program where you can play with preprocessor and recompile
• mandelbrotcmdarg - program that support arguments and you can use it "interactively", without recompilation.

How to build the original version:

There is no makefile, to compile just do:

gcc mandelbrot_original.c

This will produce file called ./a.out

Usage:

You can start the programs that does not require any arguments simply as:

./mandelbrotcmd > x.pgm

./a.out > x.pgm

x.pgm is text based graphic format, not so different from GIF, you can see it with several image viewers.

Usage of mandelbrotcmdarg is similar:

Print arguments:

./mandelbrotcmdarg

Produce a picture and save it in file x.pgm:

./mandelbrotcmdarg 800 600 0 0 16 0 0 3 > x.pgm

Now you can use batch files and create a video using mandelbrotcmdarg and ffmpeg...
