Three.js Lighting
When to Use
- You need to add or tune lighting in a Three.js scene.
- The task involves light types, shadows, environment lighting, or lighting performance tradeoffs.
- You want to improve scene readability, realism, or mood through Three.js lighting setup.
Quick Start
import * as THREE from "three";
// Basic lighting setup
const ambientLight = new THREE.AmbientLight(0xffffff, 0.5);
scene.add(ambientLight);
const directionalLight = new THREE.DirectionalLight(0xffffff, 1);
directionalLight.position.set(5, 5, 5);
scene.add(directionalLight);
Light Types Overview
| Light | Description | Shadow Support | Cost |
|---|---|---|---|
| AmbientLight | Uniform everywhere | No | Very Low |
| HemisphereLight | Sky/ground gradient | No | Very Low |
| DirectionalLight | Parallel rays (sun) | Yes | Low |
| PointLight | Omnidirectional (bulb) | Yes | Medium |
| SpotLight | Cone-shaped | Yes | Medium |
