Since 2006 is available in Maxima the package fractals, and IFS is the approach used in that package.
Copies of the package fractals.mac and rtest_fractals.mac are shared here as reference for further study. Also is shared a copy of the work of Krzysztof Leśniak and Nina Snigireva that can be found here (http://repozytorium.umk.pl/handle/item/6317); the file is named Sym5disjunctiveChaosGame_2020-06-02.wxm .
Some modifications will be made to Sym5disjunctiveChaosGame_2020-06-02.wxm for better understanding. I hope this could be clarifying about further implementations of the IFS approach to fractals in Maxima.
Some code and images about Kronecker based fractals are shared.
