108 short guides to opening, inspecting and sharing 3D files in a browser and on Meta Quest, Android XR and other headsets, each with its limits stated.
Which headsets and devices open a 3D model from a link, and what each one can and cannot do.
Moving, resizing and placing a model in mixed reality with hands or controllers.
Looking inside a model, counting what it is made of, and checking its size.
Opening files from CAD, BIM, electronics and machining tools without owning the tool.
One page per format: what opens, what is read from it, and what is not.
Downloading a model you opened as one GLB, an STL for a slicer or a USDZ for AR Quick Look.
Gaussian splats, phone scans, LiDAR point clouds and photogrammetry tiles.
Turning photos, videos and real objects into 3D models.
What the camera can recognise: things in the room, the model that matches them, and a chess position.
Links, QR codes, the public gallery, and where your own files are kept.
Talking to an assistant about the model in front of you.
Every guide is also published as plain text for language models at llms-full.txt.
