Understanding Three.js in 2025

Three.js remains one of the most popular JavaScript libraries for 3D graphics because it simplifies the process of creating complex scenes in the browser. To start with animations in Three.js, it’s essential to have a basic understanding of its 3D concepts: scenes, cameras, and renderers.

Here’s a quick refresher:

  1. Scene: This is where you set up all your 3D elements. It acts as a container for 3D objects, lights, cameras, and more.

  2. Camera: Think of it as your view or the perspective through which you look at your scene.

  3. Renderer: This is responsible for drawing your scene and camera onto the screen.

Setting Up Your Three.js Environment

The first step in creating animations is setting up your working environment. Ensure you have the latest version of Three.js and a modern browser. You can include Three.js via a CDN or by installing it through npm:

npm install three

Creating a Basic Animation

Let’s create a simple animation to get a feel for Three.js’s capabilities:

Step 1: Basic Setup

Create an HTML file and include Three.js:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Three.js Animation</title>
</head>
<body>
    <script src="https://cdn.jsdelivr.net/npm/three@latest/build/three.min.js"></script>
    <script>
        // Add your JavaScript here
    </script>
</body>
</html>

Step 2: Creating Objects

Create a basic scene, camera, and renderer:

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);

Step 3: Adding a Spinning Cube

Add a simple spinning cube to the scene:

const geometry = new THREE.BoxGeometry();
const material = new THREE.MeshBasicMaterial({ color: 0x00ff00 });
const cube = new THREE.Mesh(geometry, material);
scene.add(cube);

camera.position.z = 5;

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

animate();

Advanced Animation Techniques

  • Keyframe Animations: Use libraries like tween.js for more sophisticated animations. This allows for easing functions and complex sequences.

  • Shaders: Implement shaders for creating mesmerizing visual effects. Understanding GLSL and WebGL is a plus.

  • Physics: Use physics engines such as Cannon.js or Ammo.js to create realistic motion and interactions in your scenes.
