Looking at all the outdoor scenes that you can walk around, I wonder how long until we start seeing this in places like Google Maps/Earth, as a replacement for the low-res 3D renderings we have now. I guess the number of samples required to generate a GS is the constraint now, but maybe that will get solved.

Google already has some splats on google maps,

From the link: "Shot from 90 perspectives, 88 focus stacked images each. Nikon Z8, full frame, f/7.1, exposure 1/160, ISO 100, Laowa 180mm macro lens, with LED light and bluescreen." Insane!

And it only takes 20 Minutes to shoot all 7920 photos, the Z8 is crazy fast.

i made some decent splats (admittedly much lower quality than this) by taking video with my iphone13 mini and then chopping it up into individual frames via ffmpeg

Can you show the setup? (Can we do a Gaussian Splat of the setup of the photograph for the Gaussian Splat of the Strawberry?)

I just posted some images.. I have actually done my studio, (quality is.. let's say painterly ;-): https://superspl.at/scene/0a3916cd

THAT IS AMAZING!! Seriously, impressive work! Thanks for the link.

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: https://superspl.at/scene/e721ea7c If you navigate closer to the trees, things around you become blurry - as if the very fabric of reality unraveled.

I like that they are sort of between a photo and a 3D model. Nothing quite like it.

Can you elaborate why you chose slang-splat over let's say Lichtfeld studio? How does it compare to the other splat-training tools?

I usually use PostShot.. but the quality was not very good. I want to try LichtFeld but my Graphics Card has too little memory.. so I reached out on twitter, some people ran tests and Mykhailo got some better quality out of it so I took his training. You can d/l the COLMAP dataset for free and try yourself.

Earlier quoted context omitted.

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

I glue mounted the strawberry on three nails and used pins to secure it. I have to think about your idea.. I don't think friction would be enough to hold it in place.. it would probably be hard to knot the top onto something too, as that's where the light is: https://i.imgur.com/vIjw6pc.jpeg

But I'm always experimenting with the mounting, thanks for the inputs.

Wow this is a time killer... ended up here: https://superspl.at/scene/ff1d0393 beautiful!

It’s amazing this runs perfectly smooth on my iPhone 12 mini

That is indeed a very cool scene being about to wander around and still have decent resolution
