Fundamentally it’s an image model predicting out frames of a sequence.

It’s not enough to call it just an image model though. Not quite video either because it’s so specific to rendering images of the world.

Thus, “world model”?

The problem I have with “world” is it should imply so much more depth. To me this is actually a “POV image model” or “First-person perspective model” (maybe we call this an FPM).

There could also be TPMs (third-person models).

This maps better to modern game and 3D dev phrasing, where “world model” might imply 3D object collections spatially organized in a cohesive file format - complete with interactivity, audio, and all the baseline constituents of what one might call a “world”.

FPMs and TPMs, think about it. Reserve POVMs for photographic realism.

I think perhaps you've misunderstood what the linked repo actually is? It seems to indeed be a 3d model of an area. It's not an image model, and nothing to do with frames.

You are correct - this is threejs and not video/generative rendering which I’ve seen a lot of.

I guess “world” works if interactivity and sound etc. are considered other modalities.

Video kinda has the same issue (for me) where the audio part of the video is not part of the model.

When I think “world” I think more than just the visuals. Like a “film” model to me would imply sound and more than just the video.

We typically call 3D art “models” too, so I guess it can’t be called a model model, idk the word “world” doesn’t seem right to me
