How to make your first Three.js project with Vite+Javascript

Today we will learn what is Three.js and how we can get started with it by making a simple project on it.

Three.js is a JavaScript library for creating and displaying interactive 3D computer graphics in a web browser. It makes use of WebGL, a low-level graphics API for modern web browsers, to render 3D graphics in a browser window. Three.js has a wealth of resources and examples available, making it a great choice for developers looking to create engaging and immersive 3D experiences on the web.

PREREQUISITES:

Basic knowledge of HTML, CSS and Javascript.
A basic understanding of 3D graphics and concepts, such as scenes, cameras, and meshes.
NodeJS installed in your system.

STEPS:

Make a Directory for your three.js project and open the command line there and write:
```
 npm init vite
```
and select vanilla javascript for your project. This will initialize your project folder there.
Go inside your project folder:
```
 cd your-project-name
```
Open your project with any code editor you prefer and delete the unnecessary files and data in main.js
Install npm in your project and install three.js by the following commands:
```
 npm install
 npm install three
```

Now you have everything ready, just add the boilerplate below to your main.js and npm run dev in your terminal.

 import * as THREE from 'three';

       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( 1, 1, 1 );
             const material = new THREE.MeshBasicMaterial( { color: "orange" } );
             const cube = new THREE.Mesh( geometry, material );
             scene.add( cube );

           camera.position.z = 3;
           camera.position.y = -0.5;
           camera.position.x = -1;

       renderer.render( scene, camera );

This will make a cube on your screen which you have made using Three.js.
There are endless possibilities with Three.js, I am also learning it on my journey and you can too. Just keep exploring and we can make wonders.
