Self-replicating words (and Rauzy fractals)

This is a Go implementation of the self-replicating words and Rauzy fractals. Details on mathematical settings can be found here.

How to use

Self-replicating words

package main

import "github.com/hyosangkang/srw"

furn main() {
	f := srw.NewFractal(6, []int{0, 1, 0, 2})
	f.Save("test.png")
}

NewFractal(n, seq) takes two arguments. n is the number of layers (int) and seq is the sequence of letters ([]int) in the initial word. Note that large n may take a long time to compute. We hightly advise to use n start from 2 and increase it gradually. To visualize the fractal, use Save(fn) where fn is the file name (string) to save the image.

Rauzy fractal

package main

import "github.com/hyosangkang/srw"

furn main() {
	f := srw.NewFractal(6, []int{})
	f.SetRauzy() 
    f.SetBdd() // to show the boundary only
	f.Save("test.png")
}

SetRauzy() forces the fractal to be the Rauzy fractal. With SetBdd(), only the boundary points in the Rauzy fractal are shown in the image.
