11. Responsive Design: Adapts to various screen sizes, making it suitable for desktop and mobile devices.

with ThreeJS we can animate our site more efficiently and more attractive.

👟 Getting started with ThreeJS

Setup a Local Development Environment:

# Example for installing Node.js and npm (Linux)
sudo apt-get update
sudo apt-get install nodejs
sudo apt-get install npm

• Install Node.js and npm: https://nodejs.org/

Create a Basic HTML File:

• Create an HTML file using a text editor.

touch index.html
code index.html  # Opens Visual Studio Code with the newly created file

Include Three.js Library:

• Download Three.js or use a CDN.bash

# Download Three.js (if needed)
wget https://threejs.org/build/three.min.js

Set Up a Scene:

• Open index.html and add the following code.html

<script>
  // Your Three.js code goes here
</script>

Create a Scene, Camera, and Renderer:

• Add the following code to the script tag.

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

Add a Cube:

• Continue adding the cube code. javascript

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

Animate the Cube:

• Add the animation code. javascript

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

Run Your Local Server:

• Install and start a local server.

npm install -g http-server
http-server

Open Your Browser:

• Open a web browser and navigate to http://localhost:8080 or the address provided by your local server.

sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io

Inspect and Debug:

• Use browser developer tools to inspect and debug your Three.js application.
