You could in theory combine point clouds and Nanite: cull sub-pixel points and generate geometry on the fly by filling the voids between remaining points with polygons. The main issue is bandwidth, GPUs are barely able to handle Nanite; and this would be at least an order of magnitude more complex to do at runtime. Nanite is doing a lot of offline precomputation, storing some sort of intermediate models etc.

I agree, but I don't think this work is for realtime creation (like those Google models) but rather offline authoring. So the fixups can be done later.
