IFStile is a cross-platform (Windows, Mac, Linux, Android, WebAssembly) freeware program that can:

  • build any affine directed graph iterated function system (IFS) in an Euclidean space of arbitrary dimension (as 2D or 3D section)
  • fully automatically find interesting fractal shapes, rep-tiles, multi-tiles, irreptiles, carpets, dragons, etc
  • extract the boundary of self-affine tiles as directed graph IFS
  • compute dimensions of the boundary of self-affine tiles (numerically and analytically)
  • export Apophysis .flame format
  • effectively zoom IFS fractals
  • render high resolution images (with batch rendering)
  • render keyframe animation
  • create and save 3D mesh

The program uses a special rendering algorithm that can unveil complex structures of the fractal.

When you save a rendered image to PNG format, the program automatically saves all parameters (IFS, palette) inside the PNG, and you can load such PNG to the program to restore your workspace.
