I noticed that there is a Level of Detail component in beta in RealityKit, along with the new GaussianSplatResource component. Apple Maps 3D clearly uses some combination of these things, in addition to some form of streaming and compression most likely, in order to make performance acceptable. It would be nice if Apple could give us some examples of combining file compression + LevelofDetail + GaussianSplatResource in an example project. This is what will be required to make any kind of immersive 3D walkthroughs possible with these frameworks. I just randomly stumbled upon the LevelOfDetail component bc it was mentioned in a Google AI response, but otherwise there seem to be no examples that use it with respect to GaussianSplatResource (and so it’s not clear if it’s meant to be used in this way)
