Three.js Skills

Three.js (3js) is how 3D gets onto the web — but a scene is mostly boilerplate before the first object appears: renderer, camera, lights, materials, orbit controls, resize handling. The Three.js Scene Builder replaces the boilerplate with a checked brief: describe the scene in plain text, and the output is a single scene.html you open in a browser.

The skill below is the first Three.js skill on SkillU. It ships with a real brief, a working generator, evals, and a screenshot of the scene it builds — install it and make your own 3D web scene.

How the Three.js skill works

  1. Install the skill package into your agent's skills directory.
  2. Write the scene brief in plain text: objects, lights, camera and scene settings.
  3. Run the bundled generator — it validates the brief and writes scene.html plus a report.
  4. Open scene.html in a browser to orbit the scene, or drop it into any static host.

よくある質問

What is the Three.js Scene Builder?

An Agent Skill that turns a plain-text scene brief into a validated, standalone Three.js web scene. You describe objects, lights, camera and scene settings; a script checks the brief — unknown shapes dropped, duplicates rejected, bad sizes named — then generates a single scene.html with orbit controls and a turntable.

Do I need Three.js experience?

No. Write the brief in plain text, run one command, and open scene.html in a browser. The skill's SKILL.md walks through every step, and the report tells you exactly what was wrong if the brief has an error.

What do I need to view the scene?

A browser with WebGL. The page loads three.js 0.160.0 from the unpkg CDN; to run fully offline, download the module and the OrbitControls addon locally and point the import map at them.
