threejs-webgl SKILL.md skillA

threejs-webgl from 12-studio/tackl is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add 12-studio/tackl/threejs-webgl@git:20260722.40161c5

Pins git:20260722.40161c5 in mdr.lock. Pin the fingerprint instead.

Comprehensive skill for Three.js 3D web development. Use this skill when building interactive 3D scenes, WebGL/WebGPU applications, product configurators, 3D visualizations, or immersive web experiences. Triggers on tasks involving Three.js, 3D rendering, scenes, cameras, meshes, materials, lights, animations, textures, or WebGL/WebGPU rendering.

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 WebGL/WebGPU Development

## Overview

Three.js is the industry-standard JavaScript library for creating 3D graphics in web browsers using WebGL and WebGPU. This skill provides comprehensive guidance for building performant, interactive 3D experiences including scenes, cameras, renderers, geometries, materials, lights, textures, and animations.

## Core Concepts

### Scene Graph Architecture

Three.js uses a hierarchical scene graph where all 3D objects are organized in a tree structure:

```javascript
Scene
├── Camera
├── Lights
│   ├── AmbientLight
│   ├── DirectionalLight
│   └── PointLight
├── Meshes
│   ├── Mesh (Geometry + Material)
│   └── InstancedMesh
└── Groups
```

### Essential Components

Every Three.js application requires these core elements:

1. **Scene**: Container for all 3D objects
2. **Camera**: Defines the viewing perspective
3. **Renderer**: Draws the scene to canvas (WebGL or WebGPU)
4. **Geometry**: Defines the shape of objects
5. **Material**: Defines the surface appearance
6. **Mesh**: Combines geometry and material

## Quick Start Pattern

### Basic Scene Setup

```javascript
import * as THREE from 'three';
…

How to install

The exact contents, by fingerprint

mdr add 12-studio/tackl/threejs-webgl@sha256:2fb912c851db124e

The line at the top of this page pins the label git:20260722.40161c5, 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.
