The cables induce forc es that deform the initially straight, but flexible rods into 3D space cur ves at equilibrium. Rods can be open or closed, knotted, and arranged in a rbitrary topologies. We specifically focus on equilibrium states with no c ontacts among rods. Our setup can thus be seen as a generalization of clas sical tensegrities that are composed of rigid rods and tensile cables, to also support rods that elastically deform. We show how this generalization leads to a rich design space, where complex target shapes can be achieved with a small set of elastic rods. To explore this space, we present an in verse design optimization algorithm that solves for the length and placeme nt of cables such that the equilibrium state of the rod network best appro ximates a given set of input curves. We introduce appropriate sparsity ter ms to minimize the number of required cables, which significantly simplifi es fabrication. Using our algorithm, we explore new classes of bending-act ive 3D structures, including elastic tensegrity knots that only require a few internal cables. We design and fabricate several physical models from basic materials that attain complex 3D shapes with unique structural prope rties.\n\nRegistration Category: Full Access, Full Access Supporter\n\nLan guage Format: English Language\n\nSession Chair: Huamin Wang (Style3D Rese arch) URL:https://asia.siggraph.org/2024/program/?id=papers_840&sess=sess123 END:VEVENT END:VCALENDAR
