How to build the metaverse virtual world?

We can visualize Metaverse as a persistent Virtual reality environment that exists even when the user is not active. It is an amplified reality, that mixes the physical and digital worlds. Most metaverse platforms are built interoperable, to let you move virtual avatars, identities, objects and assets from one platform to another. The paradigm of metaverse has found wide acceptance in the gaming industry, especially the gaming platforms that allow users to engage with NFTs and facilitate the monetization of in-game assets. 

How to build a metaverse virtual world?

This article shows how to create a virtual reality (VR) app that will work on any VR system using JavaScript. In order to create VR websites, only a few relevant and up-to-date technology must be used. To begin, use Aframe.io, a toolkit for rendering and VR scenes using simple HTML and Javascript. Three.js, which is supported by Aframe.io, can be used to create more complex graphics. Next, use WebXR, a Mozilla-developed toolkit that allows one to interact directly with virtual reality on the web.

Using AFrame.io as a starting point
Simply add the codes using Content Delivery to have access to Aframe.io.:

< script src=”https://aframe.io/releases/1.2.0/aframe.min.js”>< /script> < /head> < body> < a-scene> < a-sphere id = “ball” position=”0 1.25 -5″ radius=”1.25″ color=”#EF2D5E”> < a-plane position=”0 0 -4″ rotation=”-90 0 0″ width=”4″ height=”4″ color=”#7BC8A4″> < a-sky color=”#ECECEC”> < /a-scene> < /body> < /html>

The important thing to notice here is that a tag has been added to the VR scene. By providing necessary tags, you can employ numerous shapes in the scene. So, while you can drag the screen to move the camera, you won’t be able to use the VR device just yet since an HTML file must be served because VR cannot run on a static file.

With nodeJS, this is simple to accomplish. Create a npm project with the javascript file below:

const http = require(‘http’)const fs = require(‘fs’)const server = http.createServer((req, res) => { res.writeHead(200, { ‘content-type’: ‘text/html’ }) fs.createReadStream(‘PUT THE NAME OF YOUR HTML FILE HERE’).pipe(res)})server.listen(process.env.PORT || 3000)

Finally, you can use Javascript to control our scene:

< script src=”https://aframe.io/releases/1.2.0/aframe.min.js”> < script> let sceneEl = document.querySelector(‘a-scene’); let dBalls = [] // Array of the balls we are about to create let orbitalRadius = 1.2 let cycle = 0 // Track angular revolution of balls for(let i = 0; i < 7; i++) { let db = document.createElement(‘a-sphere’); let ang = i * 2 * 3.14159 / (7) // Calculate angular position of the ball // Use entity.setAttribute to change a certain value db.setAttribute(‘geometry’, { radius: 0.2 }) // Some nice trig to get the ball in the right position db.setAttribute(‘position’, { x: orbitalRadius * Math.cos(ang), y: 0.5, z: orbitalRadius * Math.sin(ang) – 4 }) db.setAttribute(‘material’, { color: ‘orange’ }) sceneEl.appendChild(db) // Add the ball to the scene dBalls.push(db) // Add the ball to our array of balls for later access } let ball = sceneEl.querySelector(‘#ball’) // Grab the red ball that we created in HTML let rad = 0.1 // Radius of the ball let sign = 1 // Stores whether the ball is currently growing or shrinking let timer = setInterval(() => { rad += (0.005 * sign) // Either increase or decrease the radius of the ball ball.setAttribute(‘geometry’, { radius: rad }) // If radius is above/below threshold then flip sign if(rad >= 1.2 || rad <= 0.1) { sign *= -1 } // Rotate the dragon balls dBalls.forEach((d, ind) => { “let ang = cycle + (ind * 2 * 3.14159 / (7)) d.setAttribute(‘position’, { x: orbitalRadius * Math.cos(ang), y: 0.5, z: orbitalRadius * Math.sin(ang) – 4 }) }); cycle += 0.01 }, 50) < /script>

With less than 100 lines of code, the animated VR scene has now been successfully generated. Now, using the WebXR API, test your VR website on Chrome or Firefox. Once installed, browse to the WebXR tab and play the emulated headset while inspecting the page.

Conclusion 

The Metaverse has gained a lot of attention in recent years because it has the ability to merge the real world into the virtual world. It has already piqued the interest of the world’s most powerful IT companies, and while metaverse development is still in its infancy, big things are predicted. Startups and businesses have begun to adapt to the metaverse and its broad consequences, and companies are already conducting extensive studies on the upcoming metaverse consumerism. The metaverse is a relatively new concept in the online age, yet it will have a significant impact on society.¬†
