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.
Round spots dividing at even distances / Continuous curving maze stripes / Coral or cellular boundaries branching from edges / Self-organized marks of nearly constant thickness
Entrée du dictionnaire
- Usages idéaux
- Explaining biological spot and stripe formation in research, education and exhibitions · Growing organic surface, motion and type patterns
- Typographie
- 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.
- Matière
- Set reaction terms, diffusion rates, feed and kill rates, then iterate from a small perturbation.
- Précaution
- A hand-drawn animal print is not reaction-diffusion. Time and parameter changes must remain visible in the pattern.
- Pour approfondir
- Turing patterns / Gray-Scott model / Activator-inhibitor systems
