Excuse me but there are some 3D objects in my web pages!!!

JS

Web Browser as Universal Publishing Medium

  • If you want the widest possible audience..put it on the Web
  • If you want exposure via mobile devices..put it on the Web, and make sure the site is responsive

WebGL for Universal 3D Content

  • WebGL is GL with web wrappers
  • WebGL supported by most browsers and most mobile devices
  • WebGL led by Khronos Group (standardization/conformance is good thing)
  • ALL platforms..mobile,desktop,immersive
  • 3 BILLION DEVICES!!

The Magic of WebGL

Three.js editor

Declarative versus Imperative Graphics

  • declarative tells WHAT to draw
    • the Web page is a declarative structure
    • HTML is a declarative language describing the structure of a web page
    • actions taking place on the page via javascript are imperative
    • actions via javaScript frameworks act on 'objects' such as $('sphere').changeColor(r,g,b);
  • imperative tells HOW to draw

Declarative 3D in Web Pages

  • DOM - Document Object Model; contains graphic elements
  • Manipulating the DOM means you are manipulating graphical elements
  • Selecting elements of the DOM means you are selecting those elements of the page you wish to manipulate.
  • Of course having multi-Gb mesh type data directly in the DOM is an issue..being dealt with by a variety of compression techniques

JSBIN demos/examples

NOT a special graphics editor!!

    VR is back baby!

    This is not how VR will suck you in.

    from Tron (1982)

    Major Efforts

    • Facebook - Oculus
      • Samsung - GearVR (Oculus)
    • Microsoft - HoloLens
    • Google - Magic Leap (in stealth)
      • Dodo Case VR (commercial version of Google Cardboard)

    The Oculus Effect

    • clearly the excitement generated by Oculus (via kickstarter but mostly the $2B purchase by Facebook) instigated this second coming of VR
    • Browser vendors also get excited via the integration of WebGL and VR headsets

    The Secrets of Magic Leap are being Revealed

    48 Crazy Ideas Coming From The $2 Billion Stealth Startup Magic Leap

    VR Content

    Content Types

    • 360 degree video
    • actual movies - Oculus Story Studio - Sundance Film Festival

    Oculus (and VR) Problems

    • it's not all sunshine and happy drugs ;-)
    • strap a brick to your face
    • hands disappear, making interaction difficult
      • partial solution: Leap Motion
    • eyes focus on images that are physically on close screen..."simulator sickness"

    X3DOM and WebVR

    WebVR Use Case: 360 degree video

    • hardware and software integration
    • YouTube will be offering a 360 degree video channel
