Amartya Shankha Biswas, Erik D. Demaine, and Jason S. Ku, “Efficient Origami Construction of Orthogonal Terrains using Cross-Section Evolution”, in Origami7: Proceedings of the 7th International Meeting on Origami in Science, Mathematics and Education (OSME 2018), Oxford, England, September 5–7, 2018.

We introduce a new method of origami construction, using cross section diagrams. Instead of beginning our construction from a 2-dimensional sheet of paper, we consider a 1-dimensional cross section moving forwards in time. We obtain conditions for the validity of a particular cross section evolution sequence, and prove that the resulting folded state is isometric to a flat sheet of paper.

Subsequently, we use this machinery to design an efficient construction of orthogonal terrains, with arbitrary rational extrusion heights.
