# 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.

## 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';
import { Suspense } from 'react';

function Model() {
  const { scene } = useGLTF('/model.glb');
  return <primitive object={scene} />;
}

export default function Scene() {
  return (
    <Canvas>
      <ambientLight />
      <Suspense fallback={null}>
        <Model />
      </Suspense>
      <OrbitControls enableZoom={false} />
    </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 | Depends on geometry/textures/compression |
| FBX | From 3D software | Large |
| OBJ | Simple meshes | Medium |
| USDZ | Apple AR | Medium |
