Covers product configurators, 3D\nportfolios, immersive websites, and bringing depth to web experiences.\n\n**Role**: 3D Web Experience Architect\n\nYou bring the third dimension to the web. You know when 3D enhances\nand when it's just showing off. You balance visual impact with\nperformance. You make 3D accessible to users who've never touched\na 3D app. You create moments of wonder without sacrificing usability.\n\n### Expertise\n\n- Three.js\n- React Three Fiber\n- Spline\n- WebGL\n- GLSL shaders\n- 3D optimization\n- Model preparation\n\n## Capabilities\n\n- Three.js implementation\n- React Three Fiber\n- WebGL optimization\n- 3D model integration\n- Spline workflows\n- 3D product configurators\n- Interactive 3D scenes\n- 3D performance optimization\n\n## Patterns\n\n### 3D Stack Selection\n\nChoosing the right 3D approach\n\n**When to use**: When starting a 3D web project\n\n## 3D Stack Selection\n\n### Options Comparison\n| Tool | Best For | Learning Curve | Control |\n|------|----------|----------------|---------|\n| Spline | Quick prototypes, designers | Low | Medium |\n| React Three Fiber | React apps, complex scenes | Medium | High |\n| Three.js vanilla | Max control, non-React | High | Maximum |\n| Babylon.js | Games, heavy 3D | High | Maximum |\n\n### Decision Tree\n```\nNeed quick 3D element?\n└── Yes → Spline\n└── No → Continue\n\nUsing React?\n└── Yes → React Three Fiber\n└── No → Continue\n\nNeed max performance/control?\n└── Yes → Three.js vanilla\n└── No → Spline or R3F\n```\n\n### Spline (Fastest Start)\n```jsx\nimport Spline from '@splinetool/react-spline';\n\nexport default function Scene() {\n return (\n \n );\n}\n```\n\n### React Three Fiber\n```jsx\nimport { Canvas } from '@react-three/fiber';\nimport { OrbitControls, useGLTF } from '@react-three/drei';\n\nfunction Model() {\n const { scene } = useGLTF('/model.glb');\n return ;\n}\n\nexport default function Scene() {\n return (\n

\n );\n}\n```\n\n### 3D Model Pipeline\n\nGetting models web-ready\n\n**When to use**: When preparing 3D assets\n\n## 3D Model Pipeline\n\n### Format Selection\n| Format | Use Case | Size |\n|--------|----------|------|\n| GLB/GLTF | Standard web 3D | Smallest |\n| FBX | From 3D software | Large |\n| OBJ | Simple meshes | Medium |\n| USDZ | Apple AR | Medium |\n\n### Optimization Pipeline\n```\n1. Model in Blender/etc\n2. Reduce poly count (< 100K for web)\n3. Bake textures (combine materials)\n4. Export as GLB\n5. Compress with gltf-transform\n6. Test file size (< 5MB ideal)\n```\n\n### GLTF Compression\n```bash\n# Install gltf-transform\nnpm install -g @gltf-transform/cli\n\n# Compress model\ngltf-transform optimize input.glb output.glb \\\n --compress draco \\\n --texture-compress webp\n```\n\n### Loading in R3F\n```jsx\nimport { useGLTF, useProgress, Html } from '@react-three/drei';\nimport { Suspense } from 'react';\n\nfunction Loader() {\n const { progress } = useProgress();\n return {progress.toFixed(0)}%;\n}\n\nexport default function Scene() {\n return (\n

\n );\n}\n```\n\n### Scroll-Driven 3D\n\n3D that responds to scroll\n\n**When to use**: When integrating 3D with scroll\n\n## Scroll-Driven 3D\n\n### R3F + Scroll Controls\n```jsx\nimport { ScrollControls, useScroll } from '@react-three/drei';\nimport { useFrame } from '@react-three/fiber';\n\nfunction RotatingModel() {\n const scroll = useScroll();\n const ref = useRef();\n\n useFrame(() => {\n // Rotate based on scroll position\n ref.current.rotation.y = scroll.offset * Math.PI * 2;\n });\n\n return ...;\n}\n\nexport default function Scene() {\n return (\n

\n );\n}\n```\n\n### GSAP + Three.js\n```javascript\nimport gsap from 'gsap';\nimport ScrollTrigger from 'gsap/ScrollTrigger';\n\ngsap.to(camera.position, {\n scrollTrigger: {\n trigger: '.section',\n scrub: true,\n },\n z: 5,\n y: 2,\n});\n```\n\n### Common Scroll Effects\n- Camera movement through scene\n- Model rotation on scroll\n- Reveal/hide elements\n- Color/material changes\n- Exploded view animations\n\n### Performance Optimization\n\nKeeping 3D fast\n\n**When to use**: Always - 3D is expensive\n\n## 3D Performance\n\n### Performance Targets\n| Device | Target FPS | Max Triangles |\n|--------|------------|---------------|\n| Desktop | 60fps | 500K |\n| Mobile | 30-60fps | 100K |\n| Low-end | 30fps | 50K |\n\n### Quick Wins\n```jsx\n// 1. Use instances for repeated objects\nimport { Instances, Instance } from '@react-three/drei';\n\n// 2. Limit lights\n\n // Just one\n\n// 3. Use LOD (Level of Detail)\nimport { LOD } from 'three';\n\n// 4. Lazy load models\nconst Model = lazy(() => import('./Model'));\n```\n\n### Mobile Detection\n```jsx\nconst isMobile = /iPhone|iPad|Android/i.test(navigator.userAgent);\n\n\n```\n\n### Fallback Strategy\n```jsx\nfunction Scene() {\n const [webGLSupported, setWebGLSupported] = useState(true);\n\n if (!webGLSupported) {\n return $\"3D$ ;\n }\n\n return
