Very well done! I was pleasantly surprised how well this works on a phone.
Did you take any scans after sections collapsed? Would love to hear more about what happened.

Unlike Egyptian pyramids, the Maya built their temples layer by layer outward, so to understand them, researchers tunneled into the structures to understand the earlier phases of construction. I arranged the guided versions of the virtual tours in a rough chronology, moving from the highest to the lowest and oldest areas: the hieroglyphic stairway composing the largest Maya inscription anywhere, the Rosalila temple that was buried fully intact, and finally the tomb of the Founder of the city, Yax Kʼukʼ Moʼ.
I've been working to build on top of the Matterport SDK with Three.js--and then reusing the data in Unreal for a desktop experience or rendering for film (coming soon to PBS).

Major thanks to the Matterport team for providing support with data alignment and merging tunnels while I was living in the village near site.

I did take some scans after the collapse! After we'd dug ourselves out and crawled out on our bellies, I went back with Polycam. The collapsed section we dug through was comparatively small, maybe 4-5 meters: Section 1: https://poly.cam/capture/4BB863F2-1CC3-46E3-8BDB-232EE3057BD...? (you can see where we crawled out to the intersection here -- the whole intersection had ceiling collapse, but only the section we dug out through was fully covered). Section 2: https://poly.cam/capture/3C5BB7BD-5FC9-4C00-AE1C-84E0544C51C...
We're just lucky it wasn't a rocky ceiling that fell, that would've been much worse.
The team taking care of the tunnels is doing an amazing job with the resources they have, and they're continually backfilling tunnels now and maintaining the ones that are there. It took us about an hour to dig out.
You can compare to the intersection in the matterport version in the same vicinity: https://my.matterport.com/show/?m=r5BR6K6Qxix&ss=338&sr=-.21...
I don't want to editorialize too much, but at that moment we were totally brothers--I was still early with Spanish, and the language, country, age differences fell away, and we dug ourselves out.
