Augmented reality on the web is happening and it’s becoming easier to create! Below you will find a small test of an avatar model I created online and included in this post. The avatar can be viewed in your environment on ARCore and ARKit enabled devices.
I used ReadyPlayer.me to create a 3D personal avatar of me. On that website you can use a selfie to create a 3D model that resembles the your image. Afterwards you can make adjustments to its choices. And finally you can download the generated model as a .glb file.
A .glb file is the binary version of a glTF file. glTF is a specification for the efficient transmission and loading of 3D scenes and models by applications.
I used Google’s modelviewer to embed the the glb model file in the webpage below and enabled AR viewing.
Here’s the source of the snippet I used:
<script type="module" src="https://unpkg.com/@google/model-viewer/dist/model-viewer.js"></script> <script nomodule src="https://unpkg.com/@google/model-viewer/dist/model-viewer-legacy.js"></script> <model-viewer src="avatar.glb" ios-src="avatar.usdz" ar ar-modes="webxr scene-viewer quick-look fallback" ar-scale="auto" alt="Readyplayer.me avatar" auto-rotate camera-controls></model-viewer>
If AR mode is available this button will be visible in the bottom right corner. Depending on which mode is available on your device you will go into AR or open a model viewer.
Here’s the result of running it on an Android phone with ARCore support.
Universal Scene Description
Running the demo on an iPad was a bit more work than I anticipated. Apple only supports the use of models in the .usdz format (Pixar’s Universal Scene Description) As you can see in the modelviewer declaration above there is a separate ios-src for use on iOS devices.
I could not find a simple tool (running on Windows) to convert the .glb to .usdz. There seem to be better solutions on iOS.
I finally found a solution by importing the .glb in Blender, saving a .blend file, importing the .blend file into Unity and finally exporting the model to .usdz.
