Three.js 3D graphics library - scene setup, geometry, materials, lighting, textures, animation, loaders, shaders, postprocessing, interaction. Use when building 3D web experiences, creating WebGL visualizations, working with GLTF models, implementing custom shaders, or adding interactive 3D elements to web applications.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Three.js Skills

## Overview

Comprehensive knowledge base for building 3D web experiences with Three.js. This skill provides accurate API references, best practices, and working code examples across all major Three.js domains.

4. **Lighting** - Light types, shadows, environment lighting
5. **Textures** - UV mapping, environment maps, render targets
6. **Animation** - Keyframe animation, skeletal animation, animation mixing
7. **Loaders** - GLTF/GLB loading, async patterns, caching
8. **Shaders** - GLSL basics, ShaderMaterial, custom effects
9. **Postprocessing** - EffectComposer, bloom, DOF, custom passes

How to install

The exact contents, by fingerprint
mdr add secondsky/claude-skills/threejs@sha256:880af6aff6209063

The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
