About myself

Paul Melero

Web Developer

Demo

Immersive Web

What is it?

Virtual World experiences hosted through the browser.

Added Value

Difference between AR & VR

  • Content presented in immersive surroundings
  • Data visualizations
  • Games: 1, 2
  • Something cool nobody's thought of yet ⚡

WebXR today?

Draft. (Unstable)

Official spec and experimental Browser API that supports VR devices and controllers.

Basically, it provides performant stereoscopic rendering and positional tracking.

It doesn't do graphics.

- WebGL

- THREE.js, BabylonJS

- AFrame.js, React 360​...
