No geometry in the conventional sense. I did a demo of rendering a Gaussian splat in React Three Fiber here, you can open the linked splat file (its hosted on hugging face) if you want to see the data format. https://codesandbox.io/p/sandbox/3d-gaussian-splat-in-react-... I also have this youtube video about creating that demo https://www.youtube.com/watch?v=6tVcCTazmzo
