there was a project[0] that did a similar display over real openstreetmap data, sadly the demo[1] seems to be offline now, but there's a video of it[2].

Wow, I have many osm 3D tools but nothing has come close the pretty-ness of that one!

It contains the whole world? Where do the 3d data and meshes come from?

iirc mostly the osm building height data (see e.g. https://demo.f4map.com or https://streets.gl/), the facade textures were heuristically generated (thus the similarity to op).
