What it does

Once installed, the agent knows the Three.js library for drawing real 3D graphics in a web page. It can set up a scene, camera, renderer, lights and materials, load 3D models (glTF), add orbit or first-person controls, keep the animation smooth on phones, and clean up memory when a page changes. It also suggests a still image for users who prefer reduced motion. The guidance is a reference of common patterns and pitfalls rather than a tool that runs anything itself.

Great for

  • Front-end developers adding an interactive 3D product viewer or hero scene to a website
  • Designers who want a 3D UI moment and need working code for it
  • Developers debugging stretched canvases, slow loads, or memory leaks in an existing Three.js page

Skip it if

  • Simple background animations or decorative effects that CSS or a lightweight library can handle; the skill itself says Three.js is for full control and needs time for asset and performance work
  • Teams without a plan for 3D assets (models, textures) and performance testing on mobile devices

Try asking

  • “Build a spinning 3D product viewer for my shoe landing page using a glTF model”
  • “My Three.js canvas is stretched after resizing the window, help me fix it”
  • “Add OrbitControls and reduced-motion support to this existing scene”
  • “Review my Three.js code for memory leaks when users navigate between routes”

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Tell the agent whether the 3D element is decorative or functional, and which devices you must support, so it picks the right performance settings
  • Provide your model format and file size limits so it can recommend compression such as Draco or KTX2
  • Ask for the reduced-motion fallback explicitly if accessibility matters for your project
