Three.js Complete Guide 🌌

1. Introduction

Three.js is a JavaScript library used to create 3D graphics in the browser using WebGL.

const scene = new THREE.Scene();

2. Scene

const scene = new THREE.Scene();
scene.background = new THREE.Color(0x000000);

3. Camera

const camera = new THREE.PerspectiveCamera(
  75, window.innerWidth/window.innerHeight, 0.1, 1000
);
camera.position.z = 5;

4. Renderer

const renderer = new THREE.WebGLRenderer();
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);

5. Geometry

const geometry = new THREE.BoxGeometry();

6. Material

const material = new THREE.MeshBasicMaterial({ color: 0x00ff00 });

7. Mesh

const cube = new THREE.Mesh(geometry, material);
scene.add(cube);

8. Lighting

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

9. Animation

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