Skill0 starsChanged 3 months agoMITView on GitHub

3D scene work in the browser — a scaffolder that emits a self-contained Three.js scene as one HTML file (CDN import, OrbitControls, three-point lighting, grid, and your chosen primitives laid out), plus the design discipline for making 3D scenes that don't look like tutorial demos. No build step; open the file in a browser.

We split this skill into the rules it gives an agent

1 rule. About 0 are common, 1 is distinctive, and 0 are very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈1

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 0

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Distinctive:

    Motion with purpose: If it rotates, say why. Ambient rotation on everything is the "AI slop" of 3D.

    line 35

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

3D Design

Three.js scenes that don't look like the getting-started tutorial.

Scaffold

python3 scripts/scaffold_3d.py --objects cube,sphere,torus --out scene.html
python3 scripts/scaffold_3d.py --objects points,plane --camera 4,3,6 --bg 0x0a0a12

Objects: cube, sphere, plane, torus, cone, cylinder, points (2k-particle field). Output is one self-contained HTML file — open it, it renders, it has orbit controls.

Design discipline (what separates scenes from demos)

  1. Lighting is the scene. Ambient + key + fill at minimum; the scaffold gives you all three. A scene with one light looks like a default.
  2. One hero object. Everything else is context. The layout arranges primitives as a set — pick the one the camera opens on.
  3. Color restraint. The scaffold assigns a palette progression; keep it to 2-3 hues. Rainbow primitives read as a debug view.
  4. Motion with purpose. If it rotates, say why. Ambient rotation on everything is the "AI slop" of 3D.
  5. Verify in the renderer. Open the file, look at it, screenshot it (appshot or Playwright). A scene you haven't seen isn't done.

Pairs with

design (the taste standard), algorithmic-art (2D generative work), appshot (capture the rendered scene).

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
