But if I'm not mistaken, this technique still requires to get a ton of pictures from many angles ? It's fine for visiting an apartment or watching a cooking video in 3D, but how possibly can you apply this to a videogame that has much more degrees of freedom ? Are you gonna scan an entire city with a drone to create a GTA-like ?

> We introduce the 4D Gaussian Splatting (4D-GS) to achieve real-time dynamic scene rendering while also enjoying high training and storage efficiency.

This seems to be a rendering efficiency innovation, not particular to scanning.

That means it applies to artificially generated environments, whether photo realistic or stylized, and whether based on a real environment or a completely fictional one.

But of course, any photorealistic, extremely faithful to the smallest detail, rendering of a real place is going to involve a lot of scanning. That is true for any kind of rendering.
