What threejs does

The skill provides the agent with workflow guidance for Three.js. It covers scene setup, lighting, materials, user interaction controls, and WebGL post-processing shaders.

This entry lives inside OpenDesign under the 3d-shaders category. The agent triggers it during task planning when you mention phrases like webgl scene, 3d interactive, or three.js.

Because this catalog entry acts as a prototype declaration, complete helper scripts and assets require the upstream repository CloudAI-X/threejs-skills. Keep this dependency in mind when generating complex 3D scenes.

What it helps with

  • build an interactive 3D browser scene using Three.js
  • configure WebGL post-processing and shader effects
  • attach interactive camera controls to a Three.js canvas
  • set up mesh materials and lighting in the browser

Example prompts for the agent

  • threejs: set up an interactive cube scene with basic lighting
  • Build a webgl scene using Three.js with OrbitControls
  • Add bloom post-processing to the existing Three.js renderer
