Sound: Advanced Topics I (G6610, Fall 2015) week 6

L-systems/fractals

These topics were actually spread across week 6 and week 7, but I collected them here for ease-of-access. Fun stuff, and even a real-time fractal performance! (thanks to Anish and his Sri Lankan violin-playing)

Links

fractals:

javascript fractal microscope -- kind of slow, but well-rendered
javascript source code for generating the Mandelbrot set
google labs fractal microscope -- also a little slow, and you can zoom but not select. It does different variants of the Mandelbrot set + Julia sets too.
another js fractal microscope -- faster, image size is selectable
yet another js fractal microscope -- faster and you can set the number of iterations used to compute the point trajectory
older class -- with examples of building the "fractal delay" patch
another older class -- one of the first ones; unfortunately many of the link examples are implemented in java instead of javascript
another good older fractal class -- some useful info
still another older class -- this one with links to fractal examples by Michael Gogins
yet another older class -- good example of the Koch snowflake curve, and the idea behind the fractal delay
Profiles -- Charles Dodge's fractal piece
Nick Didkovsky's MandelMusic app -- an amazing app, unfortunately you have to enable Java for the site to run it. Arg, security! here are instructions for allowing it to happen.

L-systems:
L-systems examples -- good selection of different types
more L-systems examples -- can control the iterations
even more! -- ability to animate the construction
older class -- some good links, but most use java for the demos. darn.
another older class -- this one has some of Luke's L-systems patches
still another older class -- older class with X-windows code(!)
the oldest class for now -- older class, a few good links
Applications of Generative String Substitution Systems in Computer Music -- Luke DuBois' L-systems dissertation page (with music and videos)
Chaotic Squares by Michael Gogins (from his CD Garden of Algorithms).
Vanishing Trajectories -- L-systems music from Akira Takaoka with laser video from Keiichi Tanaka. (Akira's explanation of the L-system he used for the piece is here.
