Chaos Game
Method of describing a fractal patternOR attractor of an iterated function set.
Agents hop around randomly on the surface, instead of traditional methods of testing to see whether each iterated function is a part of the fractal (i.e. cutting).
Coined by Michael Barnsley.
The Math
Starting with any point x0, successive iterations are formed as xk+1 = fr(xk).
Where fr is a member of the given IFS randomly selected for each iteration.
The iterations converge to the fixed point of the iterated function series.
Whenever x0 belongs to the attractor of the IFS, all iterations xk stay inside the attractor and.
The Model
Start with original Serpinski Chaos Game code (written by Nick Bennett)
What happens when we vary the factor? I.E. Instead of ½, how about .23 or .75?
