Universal folding pathways of polyhedron nets [PDF]
Proceedings of the National Academy of Sciences, 2018 Significance What makes an object successful at thermal folding? Protein scientists study how sequence affects the pathways by which chained amino acids fold and the structures into which they fold. Here we investigate the inverse problem: Starting with a 3D object as a polyhedron we ask, which ones, among the many choices of 2D unfoldings ...

Closed Locally Minimal Networks on the Surfaces of Convex Polyhedra
Моделирование и анализ информационных систем, 2013 Closed locally minimal networks can be viewed as “branching” closed geodesics. We study such networks on the surfaces of convex polyhedra and discuss the problem of describing the set of all convex polyhedra that have such networks.

UNFOLDED REGULAR AND SEMI-REGULAR POLYHEDRA
Journal of Industrial Design and Engineering Graphics, 2015 This paper proposes a presentation unfolding regular and semi-regular polyhedra. Regular polyhedra are convex polyhedra whose faces are regular and equal polygons, with the same number of sides, and whose polyhedral angles are also regular and equal ...

On the computation of foldings [PDF]
FME Transactions, 2017 The process of determining the development (or net) of a polyhedron or of a developable surface is called unfolding and has a unique result, apart from the placement of different components in the plane.

ARIATIONS OF CONCAVE PYRAMIDS OF SECOND SORT WITH AN EVEN NUMBER OF BASE SIDES
Journal of Industrial Design and Engineering Graphics, 2015 Concave pyramids of second sort (CP II) are formed similarly to concave cupolae of second sort (CC II) with a comparable logic of emergence to the regular-faced convex pyramids.
