Background

We (XR Foundation) believe that the Metaverse, Web AR, VR, and XR should be easy.

We want a Star Trek future where participating in immersive communication technology and shared simulations should be as easy and natural as making a website.

• Includes a self-deployable platform, UI, worlds, avatars, and games
• Fully customizable for any kind of game, social experience, event or spatial web app
• User management, avatars and inventory with optional blockchain integration (see our Blockchain-in-a-Box repo)
• Social features like chat, groups, friends, blocking and moderation
• Complete world editing and administration
• 2D, 3D and XR Avatars with full inverse kinematics and facial expressions
• Fully networked physics using PhysX compiled to wasm
• Voice and video over WebRTC
• Instant login and location sharing with phone number or email
• Modular- Use the engine, server, client, editor and scalable devops infrastructure as needed
• OAuth login with Facebook, Google, Steam, Github or instant login with email or phone
• WebGL client deployable to iOS, Android and desktop
• Free, open source, MIT and Apache 2.0-licensed

Demo

We have better demos coming, but for now you can jump around this CC0 apartment we got from Sketchfab: https://app.theoverlay.io/location/apartment

Install

Pre-Requisites

To install XREngine locally, the following pre-reqs are required.

• Linux (many of us develop on Ubuntu), Mac OS X, or Windows (we recommend WSL2)
• Node.js v16 or later (we recommend installing via nvm or asdf.)
• C++ (for node-gyp), Python >=3.6 + PIP, make and other build tools, for compiling Mediasoup. Although most of XREngine is written in TypeScript, it uses a Mediasoup engine for WebRTC conferencing. See the Mediasoup install instructions for more details.
• Docker. (Although Docker is technically optional, running XREngine requires starting up half a dozen different services, and using Docker Compose will make your life dramatically easier.)
• MariaDB and Redis. (If you're using Docker, containers for MariaDB and Redis will automatically be started up.)

Getting Started

Let's build it together

We believe that projects like this are extremely complex and difficult, and can only be built when large groups of people work together, out in the open. If you believe that your calling is to build a free, open network that everyone, everywhere can get value from, then you are welcome in our community, and we'll do our best to get you set up.

We are always hiring talented people who want to be leaders in what is to come. Inquire with anyone who seems like they know what's going on and they'll help you find who you need to talk to.
