It's really cool, but I can't shake off an "uncanny valley" feeling, with all of the small quirks in the geometry. What I think I'd be interested in is a post-processing step where this splat is automatically converted to a 3d model that approximates each component, only falling back to the point cloud if there's no simple shape that fits the observation at a particular location.

This is close to the idea of convex splatting (recent paper) in which convex shapes are used to approximate these real 3d objects as they are better suited than gaussians

Broadcast television is amazing, and I'm so sad it's dying out. OK, maybe we don't need to tune in at 6 to watch the latest episode of "Friends" anymore, but for any kind of live events - news, sport, politics, having high-definition video you can pull right out of the air without having to worry about paying for data, latency, or bandwidth limitations, is amazing. For certain applications the internet can never comp…

? Is over-the-air TV broadcast not encrypted and compressed to oblivion in the US? Cause it definitely is here, and you're expected to pay for a decoder card, except for a small handful of channels.

It’s not encrypted but compression and reliability of the signal is a mixed bag. It’s not encrypted because congress mandated it as a condition for privatizing the analog bandwidth (ie there’s a carve out for public digital and broadcasters have to broadcast publicly accessible signal just like they had to on analog)

Wow! I'd love to read a more in-depth blog post describing how to create one of these myself, and maybe even contribute my own splats to a collaborative library for iconic landmarks. I could see interactive splats being added to Wikipedia for popular locations.

https://reddit.com/r/GaussianSplatting/ has been slowly talking about the subject for a while now. There are probably several articles and vids in the search bar.

If you want GS news, https://radiancefields.com/ reports a lot of advances all the time.

Yes... but the climate and geography alone would make it highly desirable at, say, 10x density.

Maybe you're right, but we'll never know. It would be great if they allowed some sections to develop so we can test it out. To me it is a desirable location because of the companies, not the lifestyle.

There's a difference between urban jungle and (say) nice 5 story European city buildings.

Londons problem for example is that they tried to be clever and cheap at the same time in the 60s and now we're stuck with it.

It's not encrypted, no. And the picture quality is very good. Not 4K, but good quality 720 or 1080, depending on the channel.

TIL — very cool work!
