Adobe's new image rotation tool is one of the most impressive AI tools seen

People have been using 3D models for 2D graphics for at least a decade. 3D models rotate, by default.

This demo shows generating a 3D model from a simple 2D shape. It'll fall flat on its face trying to 3D model anything non-trivial which begs the question - who cares?

Also, you'll want to animate the 3D model - which this doesn't do, so you'll soon be back to your usual 3D toolkit anyway.

The difference is that you don't need a 3D model for this.

You start with 2D vector graphics that is significantly easier to create.

This is in a wholly 2D program. The input is implied to be one completely flat vector drawing, which Illustrator turns into a 3d model, and renders back into flat vectors at multiple rotations, with no further work on the part of the artist.

(I say "implied" because that's all they're showing in the video presentation, there may be additional setup involved that they're skipping. This is inside Illustrator though, which has a long history of 3d extensions being very awkwardly shoved into a corner of its toolset.)

Yes, and the OP did acknowledge as much.
