Three.js Skill
Build immersive 3D web experiences with WebGL/WebGPU. Production-ready scenes, animations, and interactive graphics.
Just Ask Claude To…
"Create an interactive 3D product configurator with orbit controls and material swapping""Build a particle system with 10,000 stars and camera movement through space""Design a GLTF model viewer with post-processing bloom and realistic lighting""Create an animated 3D globe showing data points with raycasting interaction""Build a physics-based scene with falling objects and collision detection""Design a shader-based water surface with reflections and animated waves""Create a VR-ready scene with hand tracking and teleportation controls"What You’ll Get
- Working 3D scenes with optimized rendering, cameras, and lighting setups
- Interactive experiences using raycasting, controls, and animations
- Performance-tuned code with instancing, LOD, and frustum culling
- Advanced effects like post-processing, custom shaders, and physics integration

Common Use Cases
Product Configurator
Who: E-commerce developer
"Build a 3D car configurator with color picker, wheel options, and interior materials. Load GLTF model, add orbit controls, and update materials on button click. Include environment map for realistic reflections."Data Visualization
Who: Analytics team
"Create a 3D bar chart from JSON data with animated growth on load. Add axis labels, hover tooltips using raycasting, and orbit camera controls. Use instanced geometry for performance."Game Prototype
Who: Indie game developer
"Build a third-person character controller with physics-based movement. Load animated GLTF character, implement keyboard controls, add collision detection with Rapier physics, and camera follow."Marketing Landing
Who: Creative agency
"Design a hero section with floating geometric shapes, animated camera path, and scroll-triggered interactions. Add bloom post-processing, gradient materials, and smooth transitions between scenes."AR Experience
Who: Museum curator
"Create a WebXR artifact viewer that places 3D models in real space using AR. Load GLTF scan, add touch rotation, scale controls, and lighting that matches device camera environment."Pro Tips
- Start simple: Scene + camera + renderer + lights + object. Test early, add complexity incrementally.
- Optimize from start: Use instancing for repeated objects, enable frustum culling, monitor draw calls.
- Light strategically: Ambient + directional/spot. Shadows are expensive—use sparingly.
- GLTF over others: Compressed, optimized, supports PBR. Use Draco compression for meshes.
- Post-processing last: Performance cost. Use EffectComposer only when needed.
- WebGPU when ready: Faster compute, better performance. Fallback to WebGL for compatibility.

Key Takeaway
Three.js transforms complex 3D graphics into browser-native experiences. Load models, add interactions, optimize performance, then layer advanced effects. Start with core rendering loop, scale to physics, shaders, and VR.
