This really reminds me of level editors for games :) I wonder if this could be imported and used in something like counterstrike or unreal.
The other thing that the article doesn't mention which is really neat is that the Shipping Galleries that they picture at the Science Museum are sadly no more - so their work has preserved those galleries in virtual form, and allows them to live on, even when the physical space has been repurposed.
Edit: here's a nice video of the pointcloud of said gallery.
