L‑SYSTEM is a Unity project that implements a Lindenmayer System (L‑System) — a procedural grammar used for generating natural forms such as fractal structures, plants, and recursive patterns.
L‑Systems are a powerful method for procedural content generation. They use a formal grammar of symbols, an initial axiom, and production rules to evolve patterns over iterative steps. Though traditionally applied in botany and fractals, they can be extended to many algorithmic generation systems in games and simulations. :contentReference[oaicite:1]{index=1}
This repository contains a Unity solution that demonstrates L‑System generation logic with C# workflows.
- Implements Lindenmayer System logic within a Unity C# project
- Enables generation of recursive patterns using symbolic rules
- Provides a framework to experiment with:
- Axiom definitions
- Production rules
- Iteration counts
- Useful for:
- Procedural plants and trees
- Fractal architectures
- Algorithmic content generation in games
- Entire project developed in C# with Unity project files included :contentReference[oaicite:2]{index=2}
- 🔹 Rule‑based procedural generation
- 🔹 Modular C# implementation
- 🔹 Useful for games, simulations, art tools
- 🔹 Works inside a Unity project structure

This layout assumes typical Unity project structure — adjust names if your assets are in subfolders.
An L‑System consists of:
- Axiom – An initial string defining the start
- Alphabet – Collection of symbols used
- Production Rules – Mapping each symbol to transformation(s)
- Iterations – Number of times rules are applied to evolve the string
At each iteration, the system rewrites the string using production rules — creating increasingly complex structures. :contentReference[oaicite:3]{index=3}
In Unity, this logic can be used to spawn:
- Meshes or objects based on symbols
- Branches, leaves, or repeated patterns
- Artistic fractals and natural scenes
