# Three.js Post-Processing ## 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"; // Setup composer const composer = new EffectComposer(renderer); // Render scene const renderPass = new RenderPass(scene, camera); composer.addPass(renderPass); // Add bloom const bloomPass = new UnrealBloomPass( new THREE.Vector2(window.innerWidth, window.innerHeight), 1.5, // strength 0.4, // radius 0.85, // threshold ); composer.addPass(bloomPass); // Animation loop - use composer instead of renderer function animate() { requestAnimationFrame(animate); composer.render(); // NOT renderer.render() } ``` ## EffectComposer Setup ```javascript import { EffectComposer } from "three/addons/postprocessing/EffectComposer.js"; import { RenderPass } from "three/addons/postprocessing/RenderPass.js"; const composer = new EffectComposer(renderer); // First pass: render scene const renderPass = new RenderPass(scene, camera); composer.addPass(renderPass); // Add more passes... composer.addPass(effectPass); // Last pass should render to screen effectPass.renderToScreen = true; // Default for last pass // Handle resize function onResize() { const width = window.innerWidth; const height = window.innerHeight; camera.aspect = width / height; ca
