Overview

This skill helps you build high-performance 3D web applications using Three.js (WebGL/WebGPU). It bundles 556 searchable examples, 60 API classes, and 20 use-case templates to accelerate development. Use it to create scenes, load models, add animations, implement physics, and deploy VR/XR experiences.

How this skill works

Searchable example and API collections let you find working code for particle effects, PBR materials, GLTF loading, post-processing, and compute shaders. The skill provides templates and progressive reference files from fundamentals through advanced topics like WebGPU and shader graphs. Command-line search tools filter by domain, category, complexity, or use case so you can locate relevant examples quickly.

When to use it

• When building 3D scenes, interactive visualizations, or browser games
• When you need to load or optimize 3D assets (GLTF, FBX, OBJ)
• When adding animations, physically based materials, or particle systems
• When implementing physics, VR/WebXR, or spatial audio
• When migrating to WebGPU or writing compute/custom shaders

Best practices

• Start from a minimal scene and incrementally add features to isolate performance issues
• Use GLTF for complex assets and precompute lightmaps or LODs for production
• Prefer BufferGeometry, instancing, and texture atlases to reduce draw calls
• Profile frequently and use post-processing sparingly; bake static lighting where possible
• Organize references: fundamentals → loaders/textures → performance → advanced shaders

Example use cases

• Product configurator with GLTF models, PBR materials, and environment maps
• Browser-based game with animation mixers, physics engine integration, and input controls
• Data visualization using BufferGeometry and GPU particle compute shaders
• Immersive WebXR scene with spatial audio and optimized shadows
• Architectural visualization with HDR lighting, CSM shadows, and high-res models
