Wonder how they would show the Alexander Horned Sphere?
Sorry, I work in the 3D field and what this article describes is far short of a break-through. Most 3D models are built by hand by artists. They have the polygons they need in the places they need them. This technique is only applicable if you have used a 3D scanner, which almost nobody uses, or if you just aren't any good at 3D modeling. There are about a dozen programs out there that already do this cleanup task. Maybe this one is a little bit better than others, but as described it's not exactly news.
