# WebGPU Three.js with TSL

TSL (Three.js Shading Language) is a node-based shader abstraction that lets you write GPU shaders in JavaScript instead of GLSL/WGSL strings.

## Quick Start

```javascript
import * as THREE from 'three/webgpu';
import { color, time, oscSine } from 'three/tsl';

const renderer = new THREE.WebGPURenderer();
await renderer.init();

const material = new THREE.MeshStandardNodeMaterial();
material.colorNode = color(0xff0000).mul(oscSine(time));
```

## Skill Contents

## Key Concepts

### Import Pattern
```javascript
// Always use the WebGPU entry point
import * as THREE from 'three/webgpu';
import { /* TSL functions */ } from 'three/tsl';
```

### Node Materials
Replace standard material properties with TSL nodes:
```javascript
material.colorNode = texture(map);        // instead of material.map
material.roughnessNode = float(0.5);      // instead of material.roughness
material.positionNode = displaced;         // vertex displacement
```

### Method Chaining
TSL uses method chaining for operations:
```javascript
// Instead of: sin(time * 2.0 + offset) * 0.5 + 0.5
time.mul(2.0).add(offset).sin().mul(0.5).add(0.5)
```

### Custom Functions
Use `Fn()` for reusable shader logic:
```javascript
const fresnel = Fn(([power = 2.0]) => {
  const nDotV = normalWorld.dot(viewDir).saturate();
  return float(1.0).sub(nDotV).pow(power);
});
```

## When to Use This Skill

- Setting up Three.js with WebGPU renderer
- Creating custom shader materials with TSL
- Writing GPU compute shaders
- Building post-processing pipelines
- Migrating from GLSL to TSL
- Implementing visual effects (particles, water, terrain, etc.)
