Examples

Find more examples here and on YouTube.

Overview

This project enables developers to build XR experiences using the same code that runs on the web. Exokit engine is written on top of Node and emulates a web browser, providing native hooks for WebGL, WebXR, WebAudio, and other APIs used in immersive experiences.

:eyeglasses: Exokit currently targets the following platforms:
* OpenVR Desktop VR (Steam compatible)
* Oculus Desktop (Oculus Rift/Rift S)
* Oculus Mobile (Oculus Quest/Go, GearVR)
* Magic Leap
iOS ARKit
Android ARCore
Google VR (Daydream / Cardboard / Mirage Solo)
any XR device, start a pull request with a native binding if it isn't listed here!

\* not supported yet

:electric_plug: Since Exokit supports anything that runs on the web, it powers experiences built with:
* Three.js
* Unity
* Pixi.js
* Babylon.js
* A-Frame
* Custom WebGL frameworks
* WebAssembly, TypeScript, and any language that transpiles to JavaScript

:thumbsup: Why Exokit?

- You want your WebGL/WebXR to run fast.
- You want the hot new web APIs.
- You want to add your own integrations -- including native -- into a browser environment.
- You want a lightweight browser as a hackable node module.
- You want to combine the web with a 3D engine like Unity.

:thumbsdown: Why not Exokit?

- You're looking for a traditional "web browser".
- You don't care about 3D or mixed reality.
- You're looking for strict and/or legacy standards support.

:book: Manifesto

- The future is immersive. The web is the best application platform. Javascript is the best ecosystem.
- Content should be hardware agnostic. Tomorrow will have different hardware. VR and AR should be compatible.
- It's not possible to do both 2D and 3D well. We don't do 2D. We can use an external 2D browser.
- Use your favorite game engine. Exokit is not a game engine.
- Legacy browser design choices don't make sense in XR.
- Exokit empowers and connect apps, even (especially) if they aren't designed to cooperate.
- Apps should run in "reality tabs", layers of reality that blend together.

Quickstart

$3

Download for current OS

#### Run a WebXR site (desktop)

``sh
exokit https://aframe.io/a-painter/ # start A-Painter in Exokit
`

$3

Download for Magic Leap

#### Run (Magic Leap device)

`sh
mldb connect 192.168.0.10:1131 # mldb needs to be connected; see MLDB documentation
mldb install -u exokit.mpk # downloaded or built package

Architecture

Exokit is a Javascript Node.js module.

C++ bindings hook into WebGL, WebXR, Magic Leap, Leap Motion, and various other device APIs.

const {window} = require('exokit')() to get an immersive browser in another project.

Exokit runs on Windows, macOS, Linux (x64), Linux (ARM64), and Magic Leap (ARM64).
