Thank you :)

I hope so, but it'll be a good while before we can release anything. We have tight dependencies to other not-yet-OSS libraries, and until they're released, our won't work either.

Maybe! That's the seed of a completely different research paper :)

The big difference is access to fisheye lenses a burst mode that can be run for minutes at a time, and the ability to minimize the amount of camera post processing. In principle, t…

You're looking at something called a "neural radiance field" backed by a sparse, low resolution voxel grid and a dense high resolution triplane grid. That's a bit of a word soup, b…

What's worked well for me: Find a way to put what AI/ML on your critical path. Think of it like learning a new language: classes, lessons, and watching TV helps, but nothing works …

Yes, I hope so! But it'll take at least a few months of work. We have some tight dependencies to not-yet-open-sourced code, and until that's released, any code we put out will be d…

This should absolutely be possible! The hard part is making it look natural: NeRF models (including SMERF) have no explicit materials or lighting. That means that any character ins…

Oof, there's a lot of machinery here. It depends a lot on your academic background. I'd recommend starting with a tutorial on neural radiance fields, aka NeRF, ( https://sites.goog…

In terms of the live viewer, there's actually no limit on footprint size. 300 m^2 is simply the biggest indoor capture we had!

Oops, I need to update the license files. Our code is released under the Apache 2.0 license, as in this repo: https://github.com/google-research/google-research/blob/mast...

The viewer biases towards assets closer to user's camera (otherwise you'd have to load the whole scene!). We tried training SMERF with a larger number of smaller submodels, but at …

Thanks for the feedback! I agree, we could do better with the movement UX. A challenge for another day.

You're probably thinking of 3D Gaussian Splatting (3DGS), another fantastic approach to real-time novel view synthesis. There's tons of fantastic work being built on 3DGS right now…

Block-NeRF is a predecessor work that helped inspire SMERF, in fact! https://waymo.com/research/block-nerf/

I hope to release the code in the new year, but we have some big dependencies that need to be released worse. In the meantime, you can already begin hacking on the live viewer, htt…

3D understanding as a field is very much in its infancy. Good work is being done in this area, but we've got a long ways to go yet. SMERF is all about "view synthesis" -- rendering…

Interesting effect. It does look very voxel-y. I'm not a video game developer at heart, so I can only guess how it was implemented. I doubt NeRF models were involved, but I wouldn'…

> Do you need position data to go along with the photos or just the photos? Short answer: Yes. Long answer: Yes, but it can typically be derived from images. Structure-from-motion …

Update: Code for the web viewer is here, https://github.com/smerf-3d/smerf-3d.github.io/blob/main/vie...

I can't say. I'm not familiar with BD in Cyberpunk.

I won't say too much about this, but the amount of buzz around articles these days is more of "research today" sort of thing. Top conferences like CVPR receives thousands of submis…

We unfortunately haven't tested our web viewer in Firefox. Let us know which platform you're running and we'll do our best to take a look in the new year (holiday vacation!). In th…

I hope to release code in the new year, but it'll take a while. The codebase is heavily wired into other not-yet-open-sourced libraries, and it'll take a while to disentangle them.…

Collaboration is a thing at the Big G :)
