- Abstract:
-
Motivated by making signs with depth from bendable but thick sheet material
such as metal or plastic, we analyze 2.5D structures manufacturable from a
rectangular sheet by orthogonal cuts and folds (parallel to the sheet's
edges). We provide a practical universality algorithm for folding arbitrary
pixelated 2.5D surfaces using many parallel cuts, which also supports subpixel
features in one dimension. We develop two fonts that enable textual signs
within this family of designs, and show real-world constructions from
aluminum/polypropylene composite panels. We also study what is possible with
just one cut, proving a necessary condition and developing a third font under
this restriction.
