This is the readme for "Chaos PD Externals" a set of objects for PD which
calculate various "Chaotic Attractors"; including, Lorenz, Rossler, Henon
and Ikeda. Hopefully more will be on their way.
If you have any questions/comments you can reach me at firstname.lastname@example.org

The package only includes 2 and 3 dimentional attractors. There are
outlets for each dimention. The scale of the values vary between the
different attractors. To run pd with the chaos externals use:
pd -lib chaos
The object methods are as follows:
bang: Calculate one interation of the attractor.
reset: Reset to initial conditions.
param: Modify the paramaters of the equation, the number of args depend
on the attractor. (Be careful with the parameters, an attractor
will go from stable to infinity in very few interations.)
See the example patches for clarification.
Have fun with them. I'd be happy to hear about any interesting uses you
find for them. As well as any interesting attractor equations you come
