  • Developing 3D Virtual Worlds with HTML5 and WebGL
  • Time: 50 minute session | Room:
Imagine rich 3D user-generated content, instantly shared with billions worldwide via social media, viewable in a browser with no download. Imagine multi-player theme parks, desert islands, cityscapes, historical reenactments, flythroughs of deep space, and more, shared with your friends in real time. Now imagine yourself building that, using only a browser, a text editor and an open source technology stack… all programmed in JavaScript. No way?! Way. With HTML5 and WebGL, we now have a platform for building high-performance, open 3D virtual worlds in a browser. No need for proprietary software, client downloads, expensive hosting, or licensing fees. This session covers the development stack for building that Metaverse. On the client side, it’s WebGL for real-time 3D rendering; WebRTC and WebSockets for real-time multiplayer communication; and Web Audio to make it all real with sound. On the server side, we’ll look at Node.js-based application services, storing persistent world state, security, and delivering dynamic, user-generated 3D content.
