1m^3, right? I can picture what you mean, but I'm not sure it works technically, since I think the splats for a given region are not actually bound to the region they represent. Like, for example, reflections work by having the reflection being physically behind the reflective surface. And they're all transparent, so it'd blend together.
Sure, you could think in terms of 1m^3.
Yes, you're right that composing the best picture for an eye point could (and does) use splats from all over the scene.
But I think if you limit to splats that are (entirely, mostly, partially?) inside the 1m^3 block, you'll do pretty well. And you're absolutely right that reflective surfaces would probably be the first to suffer.
Well, it's worse than that. Because if you make a 1m^3 pond cube, and then I go putting trees around it, a naive rendering would still show YOUR reflections in the pond, rather than rendering from that pond's point of view, etc, like traditional rendering.
One of Gaussian Splats strengths, that it doesn't care... becomes a problem for me.
