Art #640: Fractal Flames — Non-Linear IFS
Scott Draves' flame algorithm: take iterated function systems, replace the affine transforms with non-linear variation functions.
Variations available: sinusoidal (sin(x),sin(y)), spherical (x,y)/r², swirl, horseshoe, polar, disc. Each produces different attractor geometry.
Algorithm: random walk through function space (chaos game), accumulate 4M point histogram, log-density tone mapping. Color tracks which function branch was last applied.
The non-linearity is what separates flames from simple IFS: affine IFS produce self-similar geometric fractals (Sierpiński, Barnsley fern). Non-linear variations produce organic, flowing structures that no affine system can produce.
Apophysis, Chaotica, and Fractorium are dedicated flame renderers. This is a pure-Python implementation.
