Feature request: Cheetah3D as a Viewer for Gaussian Splats

I would love it if Cheetah3D could handle existing Gaussian Splats. Cheetah3D 8 has been converted to Metal. There is an open source project for this very purpose: MetalSplatter by Sean Cier: https://github.com/scier/MetalSplatter. I compiled it yesterday with Xcode, and it works. Unfortunately, the demo app included is extremely rudimentary, but it displays a Gaussian Splat at breathtaking speed. Wouldn't it be a reasonable effort to implement this as a viewer in Cheetah3D 9 (or even 8)? It would also be great to be able to import the Colmap file format (essentially a text file that describes the file structure of the additional resources: ply-3DGS file, images, point cloud, camera positions), as exported by Metashape, for example.

I just started working with Gaussian splats on Octane Render in OctanBlender. They are great In certain circumstances for compositing individual mesh assets into a large world environment, offering rendering speed and file size savings. But I think they would not be suitable for Cheetah3D since to effectively work with them requires real-time viewport rendering preview.

I had suggested using Cheetah3D as a viewer for existing splats rather than editing them. That said, splats can even be edited in the browser, see: https://superspl.at/editor
 
In working with them I ment compositing traditional 3D elements into / on them. Not editing the splats themselves.

You said, “But I think they would not be suitable for Cheetah3D since to effectively work with them requires real-time viewport rendering preview.” However, fully trained Gaussian splats are actually suitable for real-time previews. Cheetah3D is not a real-time rendering system at all and has managed without real-time previews of the render results so far. Splats could be visualized in Cheetah3D as a point cloud and visualized and edited together with classic mesh objects, etc. However, my initial post was simply about quick integration for the visualization of fully trained Gaussian splats.
