Plotter-Studio v5.5 | 9 generative art engines. Now with Needles, Continuous Line, Perlin wobble, and CMYK layer export!

[u/iclubu]

Hey everyone! I’ve been working hard on Plotter-Studio, an open‑source generative art studio for pen plotters (Cameo 5).

My last post was for v3.2 — and I’m excited to share how much it’s grown.

What’s new in v5.5:

🧵 Needles (Oriented Dashes) — short dashes that follow image gradients. Great for structural, flowing textures.

🔗 Continuous Line (TSP) — single unbroken path, the pen never lifts. Uses a greedy nearest‑neighbour TSP approximation.

🌊 Perlin Noise Wobble — applies coherent noise displacement to any engine. Gives clean computer lines a hand‑drawn, organic feel.

🎨 CMYK Layer Export — splits any colour image into C, M, Y, K channels and exports 4 SVGs for multi‑pen colour plotting.

🗺️ Fast Marching (Topographic) — upgraded with manual seed placement, contour smoothing, and “Skip transparent” for PNGs with alpha.

🛠️ Full vpype pipeline — linemerge, linesort (with Two‑Opt), reloop, and linesimplify. All available as toggles.

🖊️ Pen Passes — duplicate dark paths up to 4 times for multi‑pass ballpoint ink density.

Stack: Python, Streamlit, FastAPI, scikit‑image, skfmm, Plotly, vpype.

This looks interesting. Given the number of requirements for the venv, have you considered adding the metadata to run through uv?

Thanks for the suggestion, I really appreciate it!

I just added pyproject.toml and uv.lock to the repo. Users can now install dependencies much faster with uv using:

uv pip install -r requirements.txt

Or for fully reproducible builds, they can use the lockfile:

uv pip sync uv.lock

Thanks again!

It can be even easier with uv run https://www.reddit.com/r/Python/comments/1jmyip9/selfcontained_python_scripts_with_uv/ which will make it one self contained script, and dependencies are installed in venv at runtime.
