Created by Kirill Rodriguez somewhen between 2014-2015.
The whole program is a small mathematical playground visualising sequences, fractals, functions etc.
Plots a fractal. Use hjkl-=mM to scale the view and the fractal itself.
Below is obtained illustration of mandelbrot set (aka Julia set with F(z, c) = z * z + c):
Some other fractals and, in particular, Julia sets are also available (try, for example, f(z, c) = sin(z) + c.
Plots a sequence of points from stdin (above: prime number theorem illustration: (pi(x) / (x / log(x)) - 1, squeezed in width).
Plots a sequence of set numbers (from stdin) on complex plane.
Plots a hardcoded function (above: log(n))
Plots f(z) on complex plane where z is a complex number with a color depending on z.
As you can see, below is sinh(cos(z)):
Above everything this program is not very accurate because
Also, the implementation with GLUT and too many abstract layers can not be normally considered efficient, but it is enough to see something at least.
The gen/ folder contains various generators, such as of some kinds of fractals, prime numbers etc. Those are to be piped to illustrator or complex_in programs for plotting as they are written to produce input following the necessary format.
For problems on compilation or runtime stage you are always welcome to raise an issue.
In case you have a good suggestion, a better implementation or something of your interest to add, you are always welcome to make a pull request.

Use at own risk. Speed and convenience are the first priorities.
