    Networked-Aframe

    Networked-Aframe

    Web framework for building multi-user virtual reality experiences

    Multi-user VR on the Web. A framework for writing multi-user VR apps in HTML and JS. Built on top of A-Frame. Follow the NAF Getting Started tutorial to build your own example from scratch, including setting up a local server. Networked-Aframe works by syncing entities and their components to connected users. To connect to a room you need to add the networked-scene component to the a-scene element. For an entity to be synced, add the networked component to it. By default the position and rotation components are synced, but if you want to sync other components or child components you need to define a schema. For more advanced control over the network messages see the sections on Broadcasting Custom Messages and Options. Create an instance of a template to be synced across clients. The position and rotation will be synced by default. The buffered-interpolation is added to allow for less network updates while keeping smooth motion.

    Super concurrency and super high data reading speed, coupled with flexible custom models, easy-to-use templates, advanced background management system and multi-user permissions, have created a perfect NoderCMS.

The simple and easy-to-use experience brought by the Handlebars template engine can define everything without secondary development.
