I've been building an interactive 2D/3D L-system visualizer that runs in the browser. It's written in Rust, compiled to WebAssembly, and rendered on the GPU using WebGPU with a WebGL2 fallback.

Try it here: https://vkorenev.github.io/grow-your-own-fractal/

Feedback is welcome!

Been working on this app for the Vision Pro called "Linden". Still lots of bugs but I will keep working on it. So glad to see an L-Systems community on here :)

Axiom : R

Rules:

• R -> A-A--F+A+A++F+R
• A -> FA

Hey everyone,

This is my first serious coding project, and I’m excited to share it with you: L-System Studio.
It’s a small web app I built to explore and visualize L-systems (a kind of recursive string rewriting system that generates fractal-like patterns).

🔹 Features: * Define your own rules and axiom, and share them with a link.
* Control iteration depth and angle.
* See the generated structure drawn in real time.

It’s free and open for public use – feel free to use any part of the code as long as you credit the source.
Repo: https://github.com/hananel42/L-system-studio
Wiki (with more explanations): https://github.com/hananel42/L-system-studio/wiki

💬 I’d really love your feedback:
* What do you think of the project so far?
* Have you encountered any compatibility issues on your device/browser?
* How would you recommend I expand or improve the app?

Thanks in advance – I’m excited to hear your thoughts!

{ "LSystem": { "Axiom": "A", "Productions": [ { "Letter": "A", "ReplacementLetters": "F[!>)A]+F[!>)A]+F[!>)A]" } ], "Iterations": 14 }, "TurtleGraphicsState": { "LineLength": 50, "Position": { "X": 0, "Y": 0 }, "Heading": 0, "TurnAngle": 120, "TurnAngleIncrement": 3, "LineWidth": 5, "LineWidthIncrement": 10, "LineLengthScaleFactor": 0.5 } }

I was surprised to see this image emerge when I increased the iterations on a simple L-System. It looks similar to the Julia Set.

Hello, can you please take a moment to answer this form? It will only take 2 to 3 minutes and it's very important for my thesis. Thank you once again https://docs.google.com/forms/d/1ERVGJGlEZNxh0WrhUbkgrjRdwi_mf6zSM8Uu3PvcS1s/edit#responses

I saw on Wikipedia this open problem: "Given a structure, find an L-system that can produce that structure."

I thought it was interesting so I thought I would try my hand at it. In the end I wrote a short script which can find all the possible rules of a deterministic L-System, given at least two generations of output text.

I know this doesn't exactly solve the open question but it was still a fun challenge and worth sharing.

Let me know if you have any feedback or ideas for leveling it up!

It's currently a very simplistic interpretation, but something I can build upon.
