I am focusing hard on making AR for the web a reality. This repository is where I publish the code. Contact me anytime @jerome_etienne. Stuff is still moving fast, we have reached a good status though. An article has been published on uploadvr. So I wanted to publish this so people can try it and have fun with it :)
- Very Fast : it runs efficiently even on phones. 60 fps on my 2 year-old phone!
- Web-based : It is a pure web solution, so no installation required. Full javascript based on three.js + jsartoolkit5
- Open Source : It is completely open source and free of charge!
- Standards : It works on any phone with webgl and webrtc
It works on all platforms. Android, iOS and window phone. It runs on any browser with WebGL and WebRTC (for iOS, you need to update to iOS 11).
To try it on your phone, it is only 2 easy steps, check it out!
- Open this hiro marker image in your desktop browser.
- Open this augmented reality webapps in your phone browser, and point it at your screen.
You are done! It will open a webpage which read the phone webcam, localize a hiro marker and add 3d on top of it, as you can see below.
So we shown it is now possible to do 60fps web-based augmented reality on a phone. This is great for sure but how did we get here ? By standing on the shoulders of giants! It is thanks to the hard work from others, that we can today reach this mythic 60fps AR. So I would like to thank:
- three.js for being a great library to do 3d on the web.
- artoolkit! for years of development and experiences on doing augmented reality
- emscripten and asm.js! thus we could compile artoolkit c into javascript
- chromium! thanks for being so fast!
Only thanks to all of them, I could do my part : Optimizing performance from 5fps on high-end phone, to 60fps on 2years old phone.
After all this work that has been done by a lot of people, we have a web-based augmented reality solution fast enough for mobile!
Now, many people have a phone powerful enough to do web AR in their pocket. I think this performance improvement makes web AR a reality. I am all exited by what people are going to do with it :)
We are still early in the project, but here are some initial numbers to give you an idea.
- I've gotten 60fps stable on nexus6p
- Some reports Sony Xperia Z2 (2.5 years old) runs around 50fps - This is a 170 Euro phone
- Some reports ~50fps on a old nexus5, and ~60fps on nexus 9 - nexus5 is 3.5 years old!
- Some report it working on Edge on Windows phone!! 13fps on Lumia 950 for some. 40-45fps on lumia 930 for others.
Obviously your mileage may vary. The performance you get will depend on 3 things: How heavy your 3D is, How you tune your parameters and the hardware that you are using.
With this project, we bring more performance to artoolkit. artoolkit is software with years of experience doing augmented reality. It is able to do a lot!
It is marker based. It supports a wide range of markers: multiple types of markers pattern/barcode multiple independent markers at the same time, or multiple markers acting as a single marker up to you to choose.
Recently, we’ve been getting creative and working on developing new things with AR.js. One of them is playing around with shadows, syncing the position of virtual lights with reality for a more life-like finish:
We’ve been collaborating very closely with Fredrick Blomqvist. His input has had a great impact on AR.js innovation and we want to thank him. Together, we’ve been implementing refraction, giving the 3d a transparent/glassy effect. It ended up having a nice polished look. What do you guys think?
Other crazy ideas we’ve been working on include a hole in the wall and a portal into another world. We want to take AR.js to new dimensions.
- "Shared #ar is a lot more real than solo #AR." - Augmented reality principle tweet
- "The marker must be a portal from where the virtual emerges." by @AndraConnect - #AR principles at dinner 😏 tweet
- At the three.js level is the main one. It is working well and efficiently
- a-frame component - it export
<a-marker>tag. It becomes real easy to use. It allows the things three.js extension does. Here are some slides aframe-artoolkit - webvr-polyfill: it is kind of working - still a work-in-progress
A-Frame magic :) All details are explained in this super post "Augmented Reality in 10 Lines of HTML - AR.js with a-frame magic" by @AndraConnect.

We started a AR.js blog, thus we can write about all the crazy ideas related to AR.js.

- Great post about WebAR for designer by nexus interactive arts
Seminal post explaining the concept. The service is available webxr.io/augmented-website
Some applications:
- Pattern Marker Training : Generate a pattern marker with your own image.
- ARCode Generator : Generator of AR-Code (source)
- WebAR Playground : Playground running in WebAR with ar.js/chromiumAR
/three.jsis the extension to use it with pure three.js/aframeis the extension to use it with a-frame/webvr-polyfillis the WebVR polyfill so you can reuse your #AR / #VR content easily
It is all open source ! jsartoolkit5 is under LGPLv3 license and additional permission. And All my code in AR.js repository is under MIT license. :)
For legal details, be sure to check jsartoolkit5 license and AR.js license.
We did good on performance, but there are still a lot of room for optimisation. Using webworkers would increase cpu usage. Compiling in webassembly instead of asm.js should improve loading time and likely cpu performance. And obviously, we can still do more parameters tweaking :)
I would like people start experience augmented reality and play with it. This is highly creative! Just look at this puzzle game in #AR playing with mirror and laser beam. You could do it with AR.js, so opensource and running on normal phones, no need to buy a new device. isn't that great!
Augmented reality on phone have applications in many fields: history education , science or gaming. I exited to see what people will do with AR.js :)
Demo tested on the following browser setups:
- Desktop Chrome with webcam and 2 tabs (one for Hero, one for result) (works!)
- Android native 4.4.2 (doesn't work, doesn't ask for permission to use camera. I see white background and text)
- Android native 5.0 (doesn't work, doesn't ask for permission, I see white background and text)
- Chrome on Android 4.4.2 (works!)
- Chrome on Android 5.0 (doesn't work, asks for permission, I see black background, text and a chart)
- Safari and Chrome on iOS < 11 (doesn't work, doesn't ask for permission, I see white background and text)
- Microsoft Edge on Windows 10 (Chrome on Google Pixel phone to view hologram)
