My intuition is that in theory focus stacking should not be necessary as preprocessing step for 3dgs (or photogrammetry). Does anyone know if there is any recent developments in this regard?

Focus stacking generally is not perfect process and can lead to artifacts/errors and I'd imagine those can then compound when stacked images are used for 3dgs. Also the image focus actually provides some depth data in itself that could be useful?

Dany, this is so cool. I'm wondering if the splat community has decided this paper is valuable -- https://github.com/fraunhoferhhi/Self-Organizing-Gaussians -- looking at all the detail in the strawberry splat made me wonder how small one can get the download, and what the current state of the art is for compression.

Thanks! We have two compressed formats, the sog by PlayCanvas and spz with sparkjs. Both now support LODs and compress really well.

What happened to the bottom of that poor strawberry?

It was mounted at the bottom.. and I can't quite reach it with my camera. Might have to try some two pass way.

I wonder would a good, sharp needle and thread make for good mounting for a soft object like this? Thread the needle, pass it right through the strawberry and the secure the thread on something above and below. As long as the strawberry doesn't slide down the thread (hopefully a strawberry is light enough friction would hold it in place!)

Anyway, very cool splat, fair play

Earlier quoted context omitted.

Yup. It's rotten on the other side. Or maybe lead poisoned

Sorry if I fell for Poe's law, but just for clarity, the strawberry's rotten underside is most likely missing splats in the rendering.

Of course it is. That's where the joke comes from...

Edit. TIL Poe's law

How about green screen + rotate the strawberry on a skewer

I read [1], but I still don't quite know what I'm looking at. My guess is a 3D model reconstructed from lots of detailed pictures? [1] https://en.wikipedia.org/wiki/Gaussian_splatting

Beautiful.

What I love about gaussian splats is the way they degrade - instead of a hard cutoff or LoD changing spheres into cubes etc., they get increasingly "dreamy" - the basic idea is still there, just less detailed.

Take for example this scene:

If you navigate closer to the trees, things around you become blurry - as if the very fabric of reality unraveled.

https://youtube.com/watch?v=X8yRlA7jqEQ is how I learned about them. They're really cool!
