Three.js Post-Processing

When to Use

• You need screen-space visual effects in a Three.js render pipeline.
• The task involves EffectComposer, bloom, depth of field, color grading, blur, or custom passes.
• You are enhancing the final rendered image rather than base scene setup alone.

Quick Start

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";

// Setup composer
const composer = new EffectComposer(renderer);
