L-system Generator

L-system Generator


Welcome to the L-system Generator! This tool allows you to generate and visualize L-systems, a type of formal grammar used to model the growth of complex structures in nature, such as plants, algae, and fractals. With just a few clicks, you can create intricate patterns by defining simple rules and iterations.

Steps to Use the Tool:

  1. Adjust the parameters:
    • Define the axiom (starting string).
    • Specify the production rules.
    • Set the number of iterations to apply the rules.
  2. Click the "Generate" button.
  3. View the generated L-system string in the output area.

Functionality: This tool utilizes JavaScript to implement L-system generation. It starts with an initial axiom and applies user-defined production rules iteratively to generate a final string representing the L-system. The generated string can then be used for further analysis or visualization.


  • Ease of Use: Simple interface requiring minimal input to generate complex patterns.
  • Flexibility: Users can define their own production rules and iterations to create custom L-systems.
  • Educational: Ideal for learning about L-systems and their applications in computer graphics, biology, and art.


  1. What is an L-system?
    • L-system, or Lindenmayer system, is a formal grammar used to model the growth of natural organisms and generate complex geometric patterns.
  2. Can I define custom production rules?
    • Yes, you can specify your own production rules to generate unique L-systems.
  3. How can I visualize the generated L-system?
    • You can use various methods such as drawing algorithms or L-system interpreters to visualize the generated string as a graphical pattern.
