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.

You should be able to do this with nerfstudio: https://github.com/nerfstudio-project/nerfstudio/ I've done it a few times, you can test 3d Gaussian Splatting also instead.

Thank you! That's terrific.

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.

Hadn't seen this comment before. Why is this one not Guassian Splats or nerfs?

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 For example capturing a neighborhood in San Francisco (or any city) as it looks in 2024 for historical reference?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.

I was working towards that aiming at the medieval city of Rothenburg o.d.T. in Germany.

Unfortunately it's a lot of code writing to support rolling shutter cameras strapped to multicopters, where you capture video with short enough exposure to prevent blur. The 3D recovery has to respect the fact that the rows of the image are taken from different positions and angles, causing this up infiltrate basically the entire pipeline.

And global shutter cameras are barely accessible.

If there's some group with the man power and funding to actually pull this off, please get in touch, I would like to pick back up!

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.

Popping my comment cherry here!

I’m a 3D artist that is currently encountering staunch resistance of generating 3D models from drone captured photogrammetry of historically protected sites in Pennsylvania, USA.

I’ve had resistance from the state and county level in pursuing take off and landing permission at historical sites. Communicating my intentions of digital historic preservation with photogrammetry has been a difficult “sell”.

I’m a licensed commercial remote pilot - however I need property owner permission to take off and land. Many sites are in state/county owned property in my area.

100%! Eventually, one way or another, I think they'll be scanned every year to study the environmental effects of tourism and compare over time.

Hey I'm really sorry! It's really hard. My photo permissions at Giza took two years to secure. My only advice is to keep showing up in person and hang in there--I feel for you!

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.
