Reaction–Diffusion

反応拡散パターン / 1952– / Technique / Computational Expression

Reaction-diffusion simulation lets substances react locally while spreading at different rates, self-organizing small disturbances into spots, stripes, mazes and coral-like patterns.

Dictionary entry

Type: Place copy in low-density regions instead of eroding every letter with the pattern.
Composition: Show growth from a seed or boundary condition rather than freezing a uniform all-over print.
Material: Set reaction terms, diffusion rates, feed and kill rates, then iterate from a small perturbation.
Caution: A hand-drawn animal print is not reaction-diffusion. Time and parameter changes must remain visible in the pattern.
