Virtual World Framework

The Virtual World Framework (VWF) allows you to build collaborative, immersive applications in the browser. VWF provides:

  • Realtime state synchronization.
  • Support for immersive applications - a set of drivers for 3D, audio, video and modern graphics.

VWF applications are written in JavaScript and leverage emerging web technologies such as WebGL, WebRTC, and WebSockets to provide a full 3D environment that is automatically synchronized across clients.
