You can now own the first commit of AR.js! 👉OpenSea
AR.js is a lightweight library for Augmented Reality on the Web, coming with features like Image Tracking, Location-based AR and Marker tracking.
30/12/21 Update: There is now also a brand new OSS Web AR JS library around, called MindAR.
If you need a great Image tracking feature (also multiple image tracking) and Face tracking, go check it out!
As for now, AR.js is still the only library providing Marker based and Location based AR features.
This project has been created by @jeromeetienne, previously managed by Nicolò Carpignoli and it is now maintained by the AR.js org.
🚀For frequent updates on AR.js you can follow @the official 𝕏(Twitter) account and Watch this repo!

</html>Important! Be aware that if you are referring to external resources, in any app, especially those using NFT, you will encounter CORS problems if those resources are not in the same server of the code. If you can’t see the tracking, please open your Browser Dev Tools and check if you have CORS errors in the console. If so, you have to fix those errors in order to see your content. The correct fix is to place your resources on the same server of your code.
If you cannot do that, you can host a proxy anywhere server to solve that (https://github.com/Rob--W/cors-anywhere). Please note that several hosting services have policies that does not permit to use such server. Always check hosting services policies before using them to avoid account suspensions
