three	Build browser-based Three.js and WebGL scenes, animations, and interactive 3D visualizations with a small vanilla JavaScript starting point.

Three.js

Quick Start

Open templates/basic-scene.html in a modern browser or serve the repository over HTTP.

Use this skill for browser 3D scenes, WebGL visualization, camera and lighting setup, asset loading, or animation loops. Start with the smallest scene in templates/basic-scene.html, then add geometry, materials, lights, and controls only as required.

Core choices

• Use PerspectiveCamera for natural 3D views and OrthographicCamera for technical or isometric views.
• Keep animation time-based with Clock or elapsed timestamps.
• Dispose geometries, materials, and textures when scenes are replaced.
• Use GLTF/GLB for external models and keep assets local when reproducibility matters.
• Prefer instancing and level of detail when object count becomes the bottleneck.

The template uses a CDN for a quick standalone demo. Pin a Three.js version for production.
