There was this FPS demo recently https://playcanv.as/p/qxGSuzYq/

People have also converted some small sections of Unreal 5 demos into splats https://superspl.at/scene/692c4f91

Or perhaps use a real world scan - it was suggested this one would make an ideal setting for zombies https://superspl.at/scene/6359774f

This is "rendering a 3D world". It's basically the exact same techniques that traditional rendering uses, just with a different primitive that's not triangles. Everything else pretty much carries over.

If you mean the technique of splatting specifically, Dreams for PS4 [1] is prior art.

If you mean pre-rendering, there's Myst and games like the original FF7 for PS1.

Note that the first published work of rendering Gaussian Volumes was in this 1991 paper (https://articles.tomasparks.name/publications/Westover1991.p...) - so 3DGS is really a rehash of an old method from the 90s!

The contributions of 3DGS lie in how fast you can make them in modern GPU hardware (tiling + sorting with threads), and how to make the pipeline differentiable so that you can fit the Gaussian splats with photogrammetry data. Similar to the history of deep learning, it became technically feasible once the GPU hardware was powerful enough.

Many years ago there was a game called Casebook[1], a small little detective game where you investigated rooms for clues. But unlike similar FMV games where you jumped from point to point, it had photorealistic environments that could be smoothly walked around in, much like later lightfield or gaussian splatting experiments.

It's going to be even more impossible to find now because the present paper introduces "Gaussian point splatting".

> It uses the entire width of the monitor rather than a slender column of pixels down the middle with large blocks of unused space on either side

Umm on my machine it has 560px margin on both sides with the content being only 474px sliver in the middle?

Imo they need to pad it just a bit. My scrollbar overlaps.

Maybe use Tampermonkey?

It's not new - that was sort of my point with my other comment.

At least if it's progressive (so refines and resolves over time), this has been done with pointclouds in the VFX industry in GPU shaders for years in terms of stochastically drawing different points so eventually the whole point set gets rasterised to a fidelity threshold.

Monte Carlo in 3dgs is established enough that Spark [1] has been doing it for a while in the browser.

I'm not sure it does a sort. Each group of threads only handles a select number of gaussians

I believe they mean GPU threads. Plenty of cuda files in their repository.
