There are actually multiple open source ML models for 2d to 3d which is clearly what they are doing. The difference with most of them is that this is vectors.

There might actually be a similar open source model already.

But I think to create it you would build it from a database of 3d assets that you could render from many angles. Probably quite similar to the way the 2d to 3d works. I don't know maybe the typical 2d to 3d models will work out of the box or with some kind of smoothing or parameterization. Maybe if you have a large database of parameterized 3d models then you combine that with rendering in 2d from different angles then you can basically use the existing 2d to 3d model.

Are you sure that’s what they’re doing? In the demo, they show that the vector sections have been preserved, so there’s clearly more to the story. Maybe 2D -> 3D, map path to vertex, rotate, project path back into 2D?

I think it's not the same but similar.

It's 2d to 3d back to 2d and converted to vectors.
