Show HN: I 3D scanned the tunnels inside the Maya Pyramid Temples at Copan

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 surprised. It might be rare but rarer still will be people willing to deploy it unless that fate is considered a good way to go.

That tour is a remarkable use of the technology.

This is great use of the technology. There should be scans of all our national monuments, world wonders, etc. So much better a use for the tech than just Redfin.

This reminds me of a recent Lex Fridman podcast with an expert in ancient American civilizations: https://www.youtube.com/watch?v=AzzE7GOvYz8

This is very cool!

Can you share the technical background you've used for creating the 3D reconstruction? Like software packages, or algorithms used.

Are we looking at the result of packages like OpenSfM here, or COLMAP?

I don't know which is cooler. The 3D scan itself or the 3D map in the browser.

This is amazing. Thank you for sharing.

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 For example capturing a neighborhood in San Francisco (or any city) as it looks in 2024 for historical reference? Seems like that should be a thing.

I've seen high quality environmental scans, even way back in the Silicon Graphics days when they showed an amazing scan of the Sistine Chapel. But it seems to me all such scans wind up in some proprietary player format which was designed by somebody who never played a decent open world game like Fallout 4, Cyberpunk, Battlefield, Red Dead Redemption. I have yet to see a museum environmental scan which gets anywhere near the immersive quality of those games. This is not so much a criticism of such work - it's awsome! - but maybe more of a call to arms for game people to help out the scholars.

Were the tombs and other structures originally sealed in with no path to the outside world? Were there other rooms accessible for rituals without archaeologists having to excavate tunnels in the modern day?

Wow! That sure brings back memories. I've been there twice, 2011 & 2012. Congratulations. I'm very impressed.

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.

The fact that people carved this tunnels with simple tools and their bare hands into the underground is so freaking amazing i cant find better words for it

Edit: also very nice tool :)!

Definitely one of the better implementations I've seen using Matterport's SDK, nice work.

Did you use the Pro3 as the capture device? Before the collapse anyway!

That is so cool.

Is it hard to avoid integrator error in long tunnels?

I love all these Maya inscriptions. I hope more are discovered (and hopefully some manuscripts) - the little we do have of Maya text is amazing. What are your top 3 things to tell people at parties that no little about Maya?

oidar | 13 hours ago

Very cool. Any other Maya sites in the pipeline to do?

Is there any plans to support a WebXR interface in the future?

hexnuts | 6 hours ago

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.

The transitions are much smoother than Google street view

This is great! Great job!

Luke I'm so happy to see you here on HN. What you and the Mused team are doing is incredible.

Does anyone know if there’s a simple solution to generating NeRFs from a continuous all directional camera (like a GoPro Max). It would be fun to make an explorable universe like that.

Amazing. So inspiring!
