A helper library extending three.js for building augmented reality web experiences that run in Google's experimental WebARonARKit and WebARonARCore browsers. It provides classes like ARReticle and ARPerspectiveCamera that interface with the WebVR Extension for AR.

Use cases

  • build AR web experiences with three.js
  • render 3D objects anchored to real-world surfaces in the browser
  • draw a reticle on detected real-world surfaces
  • match a three.js camera to the device camera video feed
  • prototype AR apps for ARKit and ARCore via web technologies

When to choose

  • you are specifically targeting WebARonARKit/WebARonARCore or the WebVR AR extension
  • you want three.js-based AR helpers like reticles and AR cameras

When to avoid

  • you need modern WebXR support - use three.js's built-in WebXR APIs instead
  • you are starting a new AR web project today - this library is unmaintained since 2018
