Are you planning an AR view for Model-Viewer?

[makenb]

Hi, awesome work! I was searching for a VR/AR port of openscad and it led me to this project. Model-Viewer has AR function built in, where if you are wearing a VR headset it allows you to view model in full 3D. It would be incredible if it was implemented. I'm sure you have plenty of work to do, but maybe something for the future. More info here: https://modelviewer.dev/examples/augmentedreality/

Hey @makenb , thanks for the kind words and for filing this!

AR kinda sorta works on the playground on compatible (mobile) devices right now, but the scale seems quite off / too large (on the default demo model at least; and when scaling it down in the AR it tends to disappear easily on my iPhone).

Definitely something to play with.

Cc/ @elalish: are there any best practices to ensure objects / scenes are likely to fit in AR? Or do we need to do our own pre scaling?

Thanks for your response! Yes I see playground AR mode does try to work on my phone, but fails to open the object. On quest headset it doesn't even show the option, however on the Model-Viewer Demo page It does work. Puzzling!

Thank You.

glTF is defined in meters, so if you're coming from OpenSCAD's mm, you'll need to ensure you add a 1/1000 transform in your GLB export. The whole point of AR is to show things at real world scale. If you might model something at a non-human scale, you'll probably want some option to give an AR scale factor, or take an automated guess.

We only recently added the VR feature to MV, so you may need to upgrade to the latest version.
