I've recently watched a talk in which @cdata talks about search engines displaying 3D models automatically, and saw that for some websites this is already happening. Do I need to configure anything else so that Google does the same for my websites?
Search for "Muscle flex visible body" --> "View in 3D" button is displayed on search results from the website

Search for "Lumini ufo t" --> "View in 3D" button is not displayed, even though the model-viewer is present on the website
@aviggiano: don't think Google has released any documentation on that. But I think once they open this up for developers you will be able to find that info here:
https://developers.google.com/search/docs/guides/search-gallery
Thanks @lanxinger, I didn't know about that link. I'll close this issue then.
@aviggiano I am just guessing here. Maybe someone from the Google team here can comment more if that really is the case.
@aviggiano actually just found this:
https://developers.google.com/search/docs/guides/3d-ar
You can register for early access.
@lanxinger @aviggiano i founds this:
https://developers.google.com/ar/develop/java/scene-viewer#3d-or-ar
but I don't know how to use it
@Sbstnlhmchr yes, this is android's new default AR model viewer. I have used it and it works well. but model viewer is much more flexible.
