The Voiijer app currently only accepts Apple’s native 3D file format .USDZ
They are just another observation type. The only difference is that you have to create the 3D (xxxx.usdz) file in another program, and then upload it into the app.
Check out this presentation or the Discussions & Deep-dives section below for suggestions on the three free apps you can use to create 3D scans to then upload into your Voiijs.
You can also:
- Find existing 3D scans with CC/CCO usage on Sketchfab (or public institutional sites).
- Convert existing scans you may have to .USDZ (Sketchfab Pro allows you to do this without 3D software).
