Of course there is a huge varierty in types of '3d models' - from stylised low-poly for games etc. (what this seems to be), to refined 3d art, accurate models of existing buildings, parametric architectural product models and shader effects (e.g. https://www.shadertoy.com/ https://www.shadertoy.com/). As a side note the sketchup 3D warehouse used to be owned by Google in fact, and some of its best attributes (geolocated buildings) were lost in the google process (as part of their switch from using sketchup to populate 3d maps, to 3d city views from composite aerial photos and lidar).
