The package includes 1, 2 and 3 dimentional attractors. There are outlets for
each dimention, starting from the left, followed by three outlets for attractor
data (see the help patches for details). The scale of the values vary between
the different attractors. To run pd with the chaos externals use:
pd -lib chaos
The basic object methods are as follows:
bang: Calculate one iteration 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 other methods (parameter searching etc.)
The next release will include a script to generate your own attractor object
for chaos from the attractor attributes.
