Iterated function systems

In the display case between l-systems and classic fractals like the Mandelbrot set, we have IFSs. There is a lot of definitional overlap between these things; mostly the difference is about where they are used and the algorithms used to draw them.

  • Why does no-one (seem to) use linearised Gaussian error propagation to choose smoothing kernel size when rendering? would reduce the amount of iterations necessary to overpaint (I think it would; but there must be some reason no-one does it)
  • Is there a meaningful acoustic equivalent?
  • At some point I would like to understand how the Barnsley IFS algorithm inferred IFSs from images.
  • Construct IFS as a point process / branching processe.
