If you doubt me, take, me up on it.
Sure, I have 35 years of experiences writing computer graphics code but I am certain I would just need to provide functional description input to Claude or Codex for this.
Zero architecture or deep 3D know-how.
The only challenge/interesting part is what happens with non-planar polygons (>3 vertices). I.e. deciding if they can be unrolled (approximated with a cylindrical or conical surface enough to 'work' when cut from paper that does not stretch).
You can alleviate this problem completely by always triangulating befor calculating any unfolding solution ofc (and get zero curved surfaces in the resulting paper model thusly).
The rest is rather trivial.
I'm not saying this isn't great, I just don't understand how you could ask people to pay for it, in early 2026.
