I'm glad to hear you're working on getting an Unreal environment for these scans. I find the movement in the web version to be incredibly clunky. This really needs to have a game like environment to do it justice. In general we clearly have the technology to capture 4K-8K environments and turn them into very realistic virtual worlds. Is anybody even doing such work? For example capturing a neighborhood in San Francis…

You can download or test the Unreal version pixel streaming here: https://mused.com/netherworld-ancient-egyptian-afterlife-sim... Or here's the trailer for the project in Unreal: https://www.youtube.com/watch?v=hlNgpG9X7mc I have a lot of work keeping up with games, it's true--games are expensive to build and aiming at photorealism art style continually looks dated quickly while stylized graphics, less so. I'm trying…

lukehollis, it's true 3D gales are so long-and-didfucult to build. Maybe you get in xontact with me : I'm testing a tool that generate 3D Orlds easilly and fast. Mytoo is called free-visit thierry.milard@gmail.com

Superb! I expect whoever coated the remains with that red cinnabar stuff died rather early, probably with tooth and hair loss and severe mental issues. Perhaps this fate was expected but given that "mad hatters" were a thing until fairly recently, people can be a bit strange when it comes to dealing with poisons. The guide notes point out that only the most sacred rituals involved this red mercurial stuff. I'm not su…

It's something we have to be careful of while working on site! We're really careful around the rooms that have mercury in them--there are few that I didn't put in the guide also. I was wondering about this too: they've found high levels of mercury in the water supply at Maya cities and believe now it contributed to the eventual collapse: https://arstechnica.com/science/2020/06/mercury-and-algal-bl...

Advanced civilizations get good at using unusual materials like lead and mercury. Some of these come with unforeseen consequences. Plastic and oil are the two substances most like these for us in present day.

Earlier quoted context omitted.

> “The drinking and cooking water for the Tikal rulers and their elite entourage almost certainly came from the Palace and Temple Reservoirs,” wrote Lentz and his colleagues. “As a result, the leading families of Tikal likely were fed foods laced with mercury at every meal.” This makes me think: what if today's rulers are being poisoned by something making them act like idiots?

> This makes me think: what if today's rulers are being poisoned by something making them act like idiots? Leaded gasoline! With how old politicians are in the US, they are almost certainly affected.

They're also old enough to have drank tap-water from lead pipes daily for decades (I learned on HN that it was mandatory for building companies in Chicago to install lead pipes until the 70s).

I think you misunderstood that comment a bit

I think the commenter misunderstood the article a bit. I was trying to give benefit of the doubt.

I love the inscriptions too--the stela only get more meaningful the more you learn about them. But it's kind of like Egypt, the iconography is harder to understand because we inherited from a different culture. For me, the Maya have always been important because they're our history and our stories in the Americas (I'm from the US) -- more than the greco-roman mythology I grew up with. They grew corn and love ball gam…

Feynman was very interested in Maya writing, but made no useful contribution to its interpretation. Credit for that goes to Knorozov and many others ( https://en.wikipedia.org/wiki/Maya_script#Decipherment); Feynman's approach followed Thompson's, which we know now to be incorrect.

Thanks for the correction!

Very nice. Small improvement idea: Move the camera along paths in such a way that it does not glitch through solid earth.

Thanks, I always wonder if it'll be too slow for people to follow the whole pathway--this will definitely be fixed in the desktop version.

This is great. I think you shared 3d scan of some other pyramid sometime ago here on HN. I think you should try processing this data through a Guassian Splatting software. I have no idea how many images Guassian Splats require to work well or the CPU/GPU requirements but I have seen very very cool Guassian Splatting demos on twitter where you can absolutely freely fly around the scene and view it from any angle.

Hey, yeah that was me. I spent quite a bit of time last year using pre-existing scanner positions to train nerfs/splats and didn't get anything that was usable, unfortunately. I ended up shifting to Unreal for a higher graphics tier, so if you want to see the Great Pyramid of Giza interior in the highest quality level, you can here: https://mused.com/netherworld-ancient-egyptian-afterlife-sim... For Unreal I used a f…

Really appreciate the use of technology to make sites like these accessible to the world at large.

Just wanted to share that I am in the middle of a very similar project with a high profile client & the workflow we settled on has loosely been Lidar scans -> Postshot -> Supersplat (web optimization) -> Babylon.js. Of course we have video/image fallbacks & an unreal pixel streaming version as well - but the web performance and results on a modern mobile device have been spectacular so far!

So excited for the future of gaussian splatting :)

Fantastic work! Just a small suggestion, I didn't realize that you could free explore the entire area until coming back and reading the comments on this site, I realized you could look around and there was one point in the guides tour where it mentioned you can explore but at least for me I didn't realize you could explore everywhere (especially the tunnels afterwards)

Maybe it's just that I'm on mobile, and when I went back I then saw the "free explore" button on the top... But maybe would be nice to add a couple prompts like you have at that one point which say something like "feel free to explore around the tunnels and then click next when you're ready to continue" or something (also for the ball court)...

Thanks for letting me know! That makes good sense, and I did this in other tours. I'll see what I can do.
