Mandelbrot Set

The Mandelbrot set is the set of complex values of c for which the orbit of 0 under iteration of the complex quadratic polynomial remains bounded.

In jFractal, you can change the quadratic polynomial to whatever you like.

Julia Set

If f is a polynomial, then is the boundary of the filled Julia set; that is, those points whose orbits under iterations of f remain bounded.

System Requirements

  • Mac OS X 10.6 or later.
