L-system Graphics

L-systemグラフィックス / 1968– / Technique / Computational Expression

L-system graphics rewrite symbol strings in parallel and interpret them as drawing, turning a few rules into recursively growing plants, trees, mycelia and ornaments.

At a glance

Visual cues

Branches repeating one angle rule from a trunk
Self-similar detail increasing by generation
Leaves or flowers attached regularly at tips and joints
A growth grammar that survives controlled randomness

Best used for

Modeling plant growth in education, visualization and generative motion
Making reproducible branching patterns and ornament from a small rule set

Dictionary entry

Type: Set rules and generation numbers in monospace outside the generated form.
Composition: Anchor one root and plan how each generation expands into the available field.
Material: Define symbols, productions, angle, line length and stack operations, updating all symbols in parallel per generation.
Caution: Mirroring branch photography is not an L-system. Preserve the production rules that generate each generation.
