The mathematics
Fractal flames, invented by Scott Draves in 1992, are an iterated function system rendered with log-density tone-mapping. A small set of affine transformations is applied repeatedly to a moving point, but each transformation is composed with a nonlinear variation — sinusoids, spherical inversion, polar maps — that warps the result into organic, luminous forms. The log-density coloring gives the images their characteristic glow. This print is the result of millions of iterations of one specific flame parameter set.
