That’s super interesting—thanks for the feedback. I’m really curious if others have felt this also.

Yes! I felt the same and I was going to write a separate comment on that before I found this conversation. I don't know how you managed to crawl(?) through all those tunnels but it just made me sick following through the guided tour. Besides this personal note, I think this is an amazing work! Very informative, the transitions are well-thought and smooth. Thank you for sharing it with us.

Thanks so much for visiting and the feedback. Yep, I was crawling on hands and knees through the horizontal passageways--especially getting to the Subterranean Chamber was tight. After crawling down the horizontal passage, I was accidentally locked in the Queens Chamber for about an half an hour before the guards came and let me out.

Maybe we should have a content warning on the tour somewhere and for those in the future that have tunnel systems / confined spaces.. I'm sorry for everyone that felt claustrophobic during this tour!

Is this available in VR?

Yes, you should be able to open the link in a VR headset with the in-headset web browser and then fullscreen to move through the 360 images in the virtual tour Free Explore mode if you like it, but I've only been working on supporting the web experience on desktop/mobile.

A void. It looks uneven, not like a chamber, but quite large.

Stone contractor promised to deliver 1000 blocks, only installed 753 blocks. Pocketed the difference.

It was the world's first pyramid scheme.

I've used the BLK 360 before so some comment here. Essentially you scan at various points within the volume of interest, e.g. you walk around, place the scanner, scan, repeat. Each scan takes a few minutes at high angular resolution. Leica provides software called Register (or Cyclone) to match the scans together. Because you generally don't have GPS (the BLK doesn't have a GPS onboar and GPS is anyway much more inac…

Complete newbie here, but wouldn't it be possible to affix some marks on the walls to help with the stitching afterwards?

yeah, this is how things used to be done maybe 10y ago. Spheres (good for 360 symmetry) or checkerboard stickers. Problem is, nobody will probably allow You to put stickers onto the interior of the Great Pyramid.

These days there's a shift towards automatic "stitching" (scan registration) on an accompanying device (tablet or a laptop).

Here's a demo of Trimble X7 (about 3y old product). Full disclosure - I worked on part of this. Not sure how much I can go in detail, but the video shows a pretty good basic demo of how this works:

I'm getting a nice video flyby of the outside of the pyramid, and a spinny thing at the bottom that says loading, and has done since last night.

Chromium 106.0.5249.119 on Debian, JS is switched on, webgl works correctly.

Edit: I should also note that in the console I also get stats.g.doubleclick.net…AAI~&z=1802238861:1 Failed to load resource: net::ERR_CERT_COMMON_NAME_INVALID

This is awesome. I desire a high res skybox at the entrance so I can take one look back out onto the Central Field before I delve inside. It would add to the experience! Great job though I love stuff like this.

Great idea--I'll see if I can head back out to capture this along with more of the path to get to the Robber's Tunnel.

This is by far the best and most enjoyable experience I tend to have in VR. Meta Quesr is an incredible piece of device to experience this in. I can't wait to fire mine up and enjoy this ;)

I just tried it in VR on my Quest 2, and while it was neat, it was only photospheres, and wasn't really 3D. very disorienting. Weird because there is clearly a 3d model, but in VR everything seems to be a fixed distance away. I think this is a matterport limitation?

Thanks for trying it and pointing this out--I haven't been working on the VR version for this reason. The web viewer provides movement through 360 photos instead of the 3d model.
