🌌 Intro to THREE.js

THREE.js is a JavaScript library that makes working with WebGL easier. With just a few lines of code, you can create and render 3D scenes right in the browser.

💡 This scene sets up a renderer, camera, and cube. You can rotate it, move the camera, and expand with lights, models, and physics later.

🎬 Sample THREE.js Code

// Basic THREE.js Scene
import * as THREE from 'https://cdn.skypack.dev/three@0.154.0';

const scene = new THREE.Scene();
const camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
const renderer = new THREE.WebGLRenderer();
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);

const geometry = new THREE.BoxGeometry();
const material = new THREE.MeshStandardMaterial({ color: 0x00ffcc });
const cube = new THREE.Mesh(geometry, material);
scene.add(cube);

const light = new THREE.DirectionalLight(0xffffff, 1);
light.position.set(2, 2, 5);
scene.add(light);

camera.position.z = 5;

function animate() {
  requestAnimationFrame(animate);
  cube.rotation.x += 0.01;
  cube.rotation.y += 0.01;
  renderer.render(scene, camera);
}

animate();
