Architecture

I believe the "point" of the 3D model was a "because we can". I think it's really really cool plus it's a demo of their software and what their software can do. Creating the 3D model of the architect's original vision (much greater than the final product that was built) is super cool and super satisfying for him as well.

Your examples are super cool too, and if I'm not mistaken must be inspired by Habitat 67 if I have my timelines correct. Those were built in the years after the Expo in Montreal where the Habitat was originally shown off
