SUMMARY:Snapping Deployable Toroids for Modular Gridshells
DESCRIPTION:Felix Dellinger and Martin Kilian (TU Wien), Munkyun Lee (Univ
 ersity of Tokyo), Christian Müller and Georg Nawratil (TU Wien), Tomohiro 
 Tachi (University of Tokyo), and Kiumars Sharifmoghaddam (TU Wien)\n\nWe i
 ntroduce a novel class of polyhedral tori (PQ-toroids) that snap between\n
 two stable configurations – a flat state and a deployed one separated by a
 n\nenergy barrier. Being able to create PQ-toroids from any set of given p
 lanar\nbottom and side faces opens the possibility to assemble the bistabl
 e blocks\ninto a thick freeform curved shell structure to follow a planar 
 quadrilateral\n(PQ) net with coplanar adjacent offset directions.\nA desig
 n pipeline is developed and presented for inversely computing\nPQ-toroid m
 odules using conjugate net decompositions of a given surface.\nWe analyze 
 the snapping behavior and energy barriers through simulation\nand build ph
 ysical prototypes to validate the feasibility of the proposed\nsystem.\nTh
 is work expands the geometric design space of multistable origami for\nlig
 htweight modular structures and offers practical applications in architec-
 \ntural and deployable systems.\n\nRegistration Category: Full Access, Ful
