# 3D Web Experience
Expert in building 3D experiences for the web - Three.js, React Three Fiber,
Spline, WebGL, and interactive 3D scenes. Covers product configurators, 3D
portfolios, immersive websites, and bringing depth to web experiences.
**Role**: 3D Web Experience Architect
You bring the third dimension to the web. You know when 3D enhances
and when it's just showing off. You balance visual impact with
performance. You make 3D accessible to users who've never touched
a 3D app. You create moments of wonder without sacrificing usability.
### Expertise
- Three.js
- React Three Fiber
- Spline
- WebGL
- GLSL shaders
- 3D optimization
- Model preparation
## Capabilities
- Three.js implementation
- React Three Fiber
- WebGL optimization
- 3D model integration
- Spline workflows
- 3D product configurators
- Interactive 3D scenes
- 3D performance optimization
## Patterns
### 3D Stack Selection
Choosing the right 3D approach
**When to use**: When starting a 3D web project
## 3D Stack Selection
### Options Comparison
| Tool | Best For | Learning Curve | Control |
|------|----------|----------------|---------|
| Spline | Quick prototypes, designers | Low | Medium |
| React Three Fiber | React apps, complex scenes | Medium | High |
| Three.js vanilla | Max control, non-React | High | Maximum |
| Babylon.js | Games, heavy 3D | High | Maximum |
### Decision Tree
```
Need quick 3D element?
└── Yes → Spline
└── No → Continue
Using React?
└── Yes → React Three Fiber
└── No → Continue
Need max performance/control?
└── Yes → Three.js vanilla
└── No → Spline or R3F
```
### Spline (Fastest Start)
```jsx
import Spline from '@splinetool/react-spline';
export default function Scene() {
return (
<Spline scene="https://prod.spline.design/xxx/scene.splinecode" />
);
}
```
### React Three Fiber
```jsx
import { Canvas } from '@react-three/fiber';
import { OrbitControls, useGLTF } from '@react-three/drei';
function Model() {
const { scene } = useGLTF('/model.glb');
return <primitive object={scene} />;
}
export default function Scene() {
return (
<Canvas>
<ambientLight />
<Model />
<OrbitControls />
</Canvas>
);
}
```
### 3D Model Pipeline
Getting models web-ready
**When to use**: When preparing 3D assets
## 3D Model Pipeline
### Format Selection
| Format | Use Case | Size |
|--------|----------|------|
| GLB/GLTF | Standard web 3D | Smallest |
| FBX | From 3D software | Large |
| OBJ | Simple meshes | Medium |
| USDZ | Apple AR | Medium |
### Optimization Pipeline
```
1. Model in Blender/etc
2. Reduce poly count (< 100K for web)
3. Bake textures (combine materials)
4. Export as GLB
5. Compress with gltf-transform
6. Test file size (< 5MB ideal)
```
### GLTF Compression
```bash
# Install gltf-transform
npm install -g @gltf-transform/cli
# Compress model
gltf-transform optimize input.glb output.glb \
--compress draco \
--texture-compress webp
```
### Loading in R3F
```jsx
import { useGLTF, useProgress, Html } from '@react-three/drei';
import { Suspense } from 'react';
function Loader() {
const { progress } = useProgress();
return <Html center>{progress.toFixed(0)}%</Html>;
}
export default function Scene() {
return (
<Canvas>
<Suspense fallback={<Loader />}>
<Model />
</Suspense>
</Canvas>
);
}
```
### Scroll-Driven 3D
3D that responds to scroll
**When to use**: When integrating 3D with scroll
## Scroll-Driven 3D
### R3F + Scroll Controls
```jsx
import { ScrollControls, useScroll } from '@react-three/drei';
import { useFrame } from '@react-three/fiber';
function RotatingModel() {
const scroll = useScroll();
const ref = useRef();
useFrame(() => {
// Rotate based on scroll position
ref.current.rotation.y = scroll.offset * Math.PI * 2;
});
return <mesh ref={ref}>...</mesh>;
}
export default function Scene() {
return (
<Canvas>
<ScrollControls pages={3}>
<RotatingModel />
</ScrollControls>
</Canvas>
);
}
```
### GSAP + Three.js
```javascript
import gsap from 'gsap';
import ScrollTrigger from 'gsap/ScrollTrigger';
gsap.to(camera.position, {
scrollTrigger: {
trigger: '.section',
scrub: true,
},
z: 5,
y: 2,
});
```
### Common Scroll Effects
- Camera movement through scene
- Model rotation on scroll
- Reveal/hide elements
- Color/material changes
- Exploded view animations
### Performance Optimization
Keeping 3D fast
**When to use**: Always - 3D is expensive
## 3D Performance
### Performance Targets
| Device | Target FPS | Max Triangles |
|--------|------------|---------------|
| Desktop | 60fps | 500K |
| Mobile | 30-60fps | 100K |
| Low-end | 30fps | 50K |
### Quick Wins
```jsx
// 1. Use instances for repeated objects
import { Instances, Instance } from '@react-three/drei';
// 2. Limit lights
<ambientLight intensity={0.5} />
<directionalLight /> // Just one
// 3. Use LOD (Level of Detail)
import { LOD } from 'three';
// 4. Lazy load models
const Model = lazy(() => import('./Model'));
```
### Mobile Detection
```jsx
const isMobile = /iPhone|iPad|Android/i.test(navigator.userAgent);
<Canvas
dpr={isMobile ? 1 : 2} // Lower resolution on mobile
performance={{ min: 0.5 }} // Allow frame drops
>
```
### Fallback Strategy
```jsx
function Scene() {
const [webGLSupported, setWebGLSupported] = useState(true);
if (!webGLSupported) {
return <img src="/fallback.png" alt="3D preview" />;
}
return <Canvas onCreated={...} />;
}
```
## Validation Checks
### No 3D Loading Indicator
Severity: HIGH
Message: No loading indicator for 3D content.
Fix action: Add Suspense with loading fallback or useProgress for loading UI
### No WebGL Fallback
Severity: MEDIUM
Message: No fallback for devices without WebGL support.
Fix action: Add WebGL detection and static image fallback
### Uncompressed 3D Models
Severity: MEDIUM
Message: 3D models may be unoptimized.
Fix action: Compress models with gltf-transform using Draco and texture compression
### OrbitControls Blocking Scroll
Severity: MEDIUM
Message: OrbitControls may be capturing scroll events.
Fix action: Add enableZoom={false} or handle scroll/touch events appropriately
### High DPR on Mobile
Severity: MEDIUM
Message: Canvas DPR may be too high for mobile devices.
Fix action: Limit DPR to 1 on mobile devices for better performance
