There was a problem hiding this comment. Typically, we add any Sandcastle assets to the Reach out if you need access or any help getting assets uploaded to that ion account. There was a problem hiding this comment. @ggetz, is it alright if we hold off until we've settled on exactly what asset we're going to use as the demo asset before uploading to the CesiumJS account? It could be this tower, or it could be something else. Of course, we won't merge to There was a problem hiding this comment. To answer your questions:

What is the preferred nomenclature? I think I've seen "Gaussian splats"? Whatever it is, we should make sure to use it everywhere, especially in showcases like Sandcastle examples.

It depends on the context. 3D Gaussian splatting and 3D Gaussian splats are both valid. When talking about the technology itself 3D Gaussian splatting is best. When talking about the output at rest, referring to them as 3D Gaussian splats is correct.

Not crucial until this is planned to ship to sandcastle.cesium.com, but we should definitely make sure we take a pass on vocab consistency, at least for user-facing things like the Sandcastle title and ref docs.
