Markerless WebAR

  • by

Markerless WebAR is the future of Augmented Reality. There are many advancements made in WebAR but the key thing missing was, no framework would support all mobile devices or browsers. Google Chrome APIs are being released which will support WebAR in the future.

However, companies like 8th Wall already support WebAR. Only disadvantage is, it is costly even to test it as a developer.

Here is a novel solution which solves the problem and does it for free using Javascript and WebAR.

Make a folder called assets/

Rename and place all Sketchfab assets as

  • gladiador.glb
  • gladiador.usdz
  • gladiador.png

and you are good to go. Host these files on a server like Netlify. As some of the features need Https.

Change Model

If you want to change the model used, you can change it in the source code of index.html. In <model-viewer> change src to any .glb file, Change ios-src to any .usdz file. These are the key model files.
