Virtual Reality

Sick of VR

Headsets

HTC Vive

Oculus Rift

Sony PlayStation VR

Samsung Gear VR

Google

Daydream View

Google Cardboard

Microsoft HoloLens

But why?

Education

Engineering

Games

Entertainment & Movies

Other types of movies

Do I really need an app for that?

App size

One time usage

Linking

WebVR

A way of embedding content

Must work with:

  • Different platforms
  • Different hardware
  • User consent

WebVR

Project started in 2014 by

Vlad Vukićević (Mozilla)

Brandon Jones (Google)

 

WebVR API

var vrDisplay;

navigator.getVRDisplays().then(function (displays) {
  // Use the first display in the array if one is available. If multiple
  // displays are present, you may want to present the user with a way to
  // select which display to use.
  if (displays.length > 0) {
    vrDisplay = displays[0];
  }
});

WebVR API

  • Position
  • Orientation
  • Field of view
  • Depth of field
  • Various sensors
  • [others]

Everybody hates boilerplate

  • Import WebVR Polifill
  • Set up camera
  • UI for entering VR
  • Initialize scene
  • Create render loop
  • Add lighting
  • Declare canvas
  • Handle window resize

A-Frame

A-Frame

<a-scene>
  <a-sphere position="0 1.25 -1" radius="1.25" color="#EF2D5E"></a-sphere>
  <a-cube position="-1 0.5 1" rotation="0 45 0" width="1" 
          height="1" depth="1" color="#4CC3D9">
  </a-cube>
  <a-cylinder position="1 0.75 1" radius="0.5" height="1.5"
          color="#FFC65D">
  </a-cylinder>
  <a-plane rotation="-90 0 0" width="4" height="4"
          color="#7BC8A4">
  </a-plane>
  <a-sky color="#ECECEC"></a-sky>
</a-scene>

A-Frame Model

Entity - general-purpose object that inherently does and renders nothing

Component - reusable module that is plugged into entities in order to provide appearance, behavior, and/or functionality

System - provides global scope, services, and management to classes of components

A-Frame Model

<a-entity 
          geometry="primitive: sphere; radius: 1.5"
          material="color: tomato; metalness: 0.7">
</a-entity>

<!-- --------------------------------------------------- --> 

<a-scene>
  <a-assets>
    <a-mixin id="red" material="color: red"></a-mixin>
    <a-mixin id="blue" material="color: blue"></a-mixin>
    <a-mixin id="cube" geometry="primitive: box"></a-mixin>
    <a-mixin id="sphere" geometry="primitive: sphere"></a-mixin>
  </a-assets>

  <a-entity mixin="red cube"></a-entity>
  <a-entity mixin="blue cube"></a-entity>
  <a-entity mixin="red sphere"></a-entity>
</a-scene>

A-Frame Demo

Get VR content

VR: Use when appropriate

  • AAA game vs 3D panorama?
  • Does VR really make it better?
  • Feature detection. #PWA
  • Make it opt-in, not opt-out.
  • Make VR the cherry on the cake.

Future of WebVR

Useful resources

Happy hacking!
