# Three.js Post-Processing

Targets three.js r186. Examples use WebGLRenderer; the WebGPU and TSL section uses WebGPURenderer.

## Quick Start

```javascript
import * as THREE from "three";
import { EffectComposer } from "three/addons/postprocessing/EffectComposer.js";
import { RenderPass } from "three/addons/postprocessing/RenderPass.js";
import { UnrealBloomPass } from "three/addons/postprocessing/UnrealBloomPass.js";
import { OutputPass } from "three/addons/postprocessing/OutputPass.js";

const renderer = new THREE.WebGLRenderer({ antialias: true });
