Julia Sets
Julia sets are beautiful objects which arise in the study of iteration of
rational functions on the complex plane. I published a paper in Volume 7,
issue 2 of the journal Mathematica in Education and
Research which describes an efficient technique for generating
Julia sets of many rational functions. The algorithm is the same as the one
used by my Java Julia Set
Generator. Of course, the data structures are quite different and the
code is about 700 lines shorter. You can look at the paper in
HTML
or
notebook
formats. If you want to play with the code, you'll need to
download the package. The following code illustrates the basic usage.
Needs["JuliaSet`"];
Show[GraphicsArray[Partition[
Julia[#, z, Bound -> 12, DisplayFunction -> Identity]& /@
{z^2 - 0.77 + 0.22 I, z^2 + 0.68 I,
z^2 - 0.123 + 0.745 I, z^3 + z + 0.6 I,
z^3 - I, 2 z/3 + 1/(3 z^2)}, 2
]]]
