GSplatting, or [3D Gaussian Splatting](https://repo-sam.inria.fr/fungraph/3d-gaussian-splatting/), is a form of capturing scenes in a way that preserves the visual quality but doesn't provide an actual [polygonal](https://en.wikipedia.org/wiki/Polygonal_modeling) model. + +Unlike photogrammetry, GSplatting provides a fairly realistic gaussian of the captured scene that can be viewed using very little computational resources, this is a big reason why Nvidia is investing time into NeRF (actually something completely different but they're similar in output). + +Anyways, here's a quick demo that allows you to view models in a browser, I may add a few different gaussians that I've been working on, but currently I'm borrowing `bonsai-7k-mini.splat`.
