This is exactly what is needed in archeology. High quality imaging & survey, not historical speculations tied up with this or that professor’s ego-driven “school of thought”.

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 the feedback! Didn't know if people would like this. If this is interesting, and you'd like to learn more about Ancient Egypt, here are a few more sites that I've worked at: Luxor Temple: https://luxortemple.mused.org/en/guided/178/luxor-temple Tomb of Queen Meresankh III at Giza: https://giza.mused.org/en/guided/4/tomb-of-queen-meresankh-i... I've mostly been working around the Mediterranean, Central Amer…

Do you use photogrametry or do you use professional 3D scanners?

For this scan specifically, I used a Leica BLK 360 and Matterport Pro 2 Laser scanner and took photogrammetry photos as well. In the presentation layer using the Matterport SDK, only the laser scan data is displayed.

By "worked at", what exactly do you mean?

I mean a site where I partnered with a local team and sometimes international partners to complete laser scanning and then built virtual tour with the Matterport SDK.

That is insanely cool. The dollhouse view is nice. It would be great if you could see a 2D schematic of where you are in the pyramid as you're exploring. Incredible job!

Actually liked that it lacked a minimap. Got a better sense of scale. After going trough most of the tunnels and getting stuck and kings chamber there, couldn't crawl back, I zomemed out and was shocked by the scale of the tunnels.

Thanks to you both for feedback on the minimap--this is one that we've had some requests for but I haven't started on yet.

Thanks for the amazing work! Here are my notes: 1- Actual surveying of the site was a bit annoying. On one hand, I wanted to scan everything and look at every detail. On the other, I didn't know where I was and didn't want to miss out by my depth-first approach. The automatic surveying routine (clicking next) moves the camera way too fast. Also I guess it doesn't present everything we know of the site. For example I…

On mobile, for the tour, I found the camera moved a bit quickly and would also cut corners.

I think it would be helpful to break the movement down a bit and add intermediate positions. Rotate camera, move along in the direction that your head might realistically travel through the space, and then a final rotation at the destination if needed.

Amazing work! Ever since I watched the documentary about the ScanPyramids Project I've been waiting for a full 3D Scan (moreso even for a VR Project, but that's only a small step from this). I figured they were probably not allowed to publish their scans, so this is a nice surprise.

This looks a bit "segmented" to me? As in, the scanned parts are not necessarily 100% overlapping (and resulting in a single union model?). Nonetheless amazing work.

If you're interested in VR compatibility, I believe A-Frame (https://aframe.io/) (also threejs and webbased IIRC) might do the trick.

Semi-related, the Great Pyramid was also scanned using muon radiography, by which a "big void" was discovered [0]. Muons can penetrate through a lot of material, so they can see through very large, thick things like the pyramids. Muon tomography was also used to scan the Fukushima reactors [1] and see where the fuel ended up. [0] https://arxiv.org/pdf/1711.01576.pdf [1] https://www.world-nuclear-news.org/RS-Muons-sug…

Wild. I was speculating about this in 2003 on my blog. Very interesting news. https://javarants.com/deconstructing-the-pyramids-76081876b3...

I thought this was going to be a conspiracy theory, but it was an interesting read about a simple (yet intriguing) idea. Thank you for sharing.

As a side note, what's the blog architecture? I seem to remember seeing an XML error when I hit a link that does not exist (like at [1]) but I can't remember where :).

The Mused jobs link points at the blog, is that intentional?

Thanks, I'll update this--I've been working with a few of my friends this year, and I think we're still looking for product-market fit so haven't been thinking of hiring recently.

Maybe since 19th and 20th century archaeologists have a sometimes terrible track record (Elgin Marbles, Benin Bronzes, etc.), it's important to not be similarly extractive with the 3d data now but instead find ways to connect the local and international communities using the laser scans. That's one of the areas we're exploring next.

Thank you so much for your work! I loaded your tour of the Great Pyramid onto my laptop and settled into bed next to my wife, who is recovering from knee replacement surgery. I said "May I take you to Egypt for awhile?". She loved it! I really appreciate the effort you've put into giving access to historically important sites fir those of us who are unlikely to visit in person.

I love this story, and thanks for visiting & sharing! I hope she makes a quick recovery.

If it's interesting apart from the other scans I mentioned in the comments, one of the favorite places that I've worked is in the Sinai at St Catherine's Monastery:

https://stcatherines.mused.org/en/ has three scans of the Holy Summit of Mt Sinai, Burning Bush/Monastery, and Monastery Museum.
