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.

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 defined by the two or three arguments. [reset a b c] will reset the xyz values to abc respectively. 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 across.
