Mandelbrot Set

mathematics, programming, Pygame, Python, #colorful, #complex, #fractal, #f_c(z) = z^2 + c, #imaginary, #iterating, #iteration, #Mandelbrot, #repeating, #self-repeathing, #set

Working with complex numbers and iterating the function f_c(z)=z^2+c, I created this program which lets you explore the depth of this self-repeating fractal. The different colors are caused by different color schemes.

Controls

  • Left mouse click and mouse movements control the zoom frame,
  • Middle mouse click zooms in,
  • ‘Space’ takes a screenshot,
  • ‘F1’ moves a zoom back,
  • ‘F2’ zooms to default zoom.
