Weighted affine maps are sampled into a density image for the current preset. Wheel to zoom and drag to pan.

Math Notes

IFS fractals repeatedly apply one affine map chosen from a weighted collection:

The geometry emerges from the long-run distribution of points, not from a pixel-by-pixel escape-time test.

Exploration Tips

  • Change the seed to vary point visitation while preserving the same attractor.
  • Raise exposure when dense regions overpower the finer leaf or branch structure.
  • Wheel to zoom and drag to pan once you want to inspect a local branch cluster.
