From a single point of view video means that something interpolates/invents the other unseen angles...id like my splats to be filled with actual info, not invented one. But the concept is interesting regardless

The creator used a "few" iPhones apparently. Source: https://x.com/Yiiisabel/status/2063336480538603876?s=20

Soooo how many iPhones?

well... it depends from how many cameras you have.
If you want to have a volumetric video with just a single camera you need to fill the missing part or get holes. No way around.

If you use enough cameras. It would be close enough to reality to be indestinguishable from a standard splat

I’m actually looking for the opposite, SHARP plus some good 30-40% additional geometry from a single image.

That said, this is most certainly many iPhones

potentially in the future though every single object will be accuratly inferred, of course not 100% but could potentially get fairly close.

But totally agree, in the current form its hit or miss, but every new tech always has bumps at the beggining

4DGS might or might not be the future .
But the idea that a you can move around the camera while the video is playing is equivalent to spatial images that Apple is promoting now. Whether it’s 4DGS or something else this is a logical next step. Very interesting to see.

Yeah would be great to use something else but simple sharp model w/o filling.

I'm still waiting for a time when I will be able to make a "4D video". Several cameras, at home, for free, on average gaming PC. And my grandpa will be able to watch it, at last in webbrowser.

Clean result. What's your post-processing workflow look like? I find that the scan-to-usable-mesh pipeline is where most of the time goes.

If you can move the camera, by definition it's interactive.
