Open the model at 0xr.space on a Meta Quest, enter the room and press Zero on the dock. Ask what a part is, or point at it and say what is this. Zero answers aloud and lights up the parts it names for about six seconds. Ask it to show only the engine, hide the red parts, pull the model apart or cut it in half. For a list, a set of steps or a comparison it puts a note card in the room; say put it away when you are done.
Zero finds parts by the names, materials and colours stored in the file. A model whose parts are called Mesh_012 gives it little to work with, and a scan or a photo model has no parts at all. What it says about a part comes from a cloud AI service, Google's Gemini Live, so check anything important.
The file does not name it. Zero matches the names, materials, colours and simple shapes in the model; a part named only by a number cannot be found by what it is.
Yes. Ask it to show everything again or to reset the view.
Yes. On a phone or computer the same questions work on the page, with parts lighting up on screen.
The file is not. Zero is told the model's name and part names, and your speech goes to Google's Gemini Live service.
