The Dreams game engine (only for PS4) does this and is able to achieve scenes that no other game engine can. Here's a technical talk about how they did it: https://www.youtube.com/watch?v=u9KNtnCZDMI

Actually sorry not sure if they use triangle splatting, but gaussian splats at least.

Pretty sure they use SDFs, not triangle or gaussian splatting

		If I recall their talk correctly, models are unions of SDFs, which get sampled into a point cloud, and each point gets splatted as another SDF primitive called a "fleck".

		Ah thanks for the correction. The splat terminology they also use confused me.
