Möbius IFS
Previous Image | Next Image
Description: IFS using three Möbius transformations.

Coloring is from the code here: https://observablehq.com/@timhutton/mobius-ifs at version v2273. The hue works like this: at each step of the IFS we generate a number [0, 1] and select which transformation to use by dividing at [0.333, 0.666]. The value is also accumulated with exponential smoothing (smoothed_branch_value = smoothed_branch_value * 0.9 + branch_value * 0.1) which gives at the end a value [0, 1] which encodes some of the recent history of which branches were taken. Mapping this value to hue gives a visibly different color on the different parts of the pattern.
