How to create VR experiences for the browser

Let’s start with the basics. A-Frame because it makes it easy for me with what I already know of HTML5 and JavaScript. Is it WebXR compatible? Yes, it is in its current release 1.0.4.

Basic Hello World In A-Frame

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <title>Hello World A-Frame</title>
    <meta name="description" content="Hello World, WebXR! in A-Frame">
    <script src="https://aframe.io/releases/1.0.4/aframe.min.js"></script>
  </head>
  <body>
    <a-scene background="color: #FAFAFA">
      <a-box position="-1 0.5 -3" rotation="0 45 0" color="#4CC3D9" shadow></a-box>
      <a-sphere position="0 1.25 -5" radius="1.25" color="#EF2D5E" shadow></a-sphere>
      <a-cylinder position="1 0.75 -3" radius="0.5" height="1.5" color="#FFC65D" shadow></a-cylinder>
      <a-plane position="0 0 -4" rotation="-90 0 0" width="4" height="4" color="#7BC8A4" shadow></a-plane>
    </a-scene>
  </body>
</html>

So what does A-Frame give us to begin with? The Hello World example. Well that’s cool, but I want more. Like an environment around the geometric shapes and the ability to move around in VR. So let’s do that!

The best way to add an environment is with the a-frame-environment-component. I found it on GitHub here:

https://github.com/supermedium/aframe-environment-component

So add that and we get:

In the code we have:

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <title>Hello World A-Frame</title>
    <meta name="description" content="Hello World, WebXR! in A-Frame">
    <script src="https://aframe.io/releases/1.0.4/aframe.min.js"></script>
    <script src="https://unpkg.com/[email protected]/dist/aframe-environment-component.min.js"></script>
  </head>
  <body>
    <a-scene background="color: #FAFAFA">
      <a-box position="-1 0.5 -3" rotation="0 45 0" color="#4CC3D9" shadow></a-box>
      <a-sphere position="0 1.25 -5" radius="1.25" color="#EF2D5E" shadow></a-sphere>
      <a-cylinder position="1 0.75 -3" radius="0.5" height="1.5" color="#FFC65D" shadow></a-cylinder>
      <a-plane position="0 0 -4" rotation="-90 0 0" width="4" height="4" color="#7BC8A4" shadow></a-plane>
<a-entity environment="preset: forest"></a-entity>
</a-scene>
  </body>
