SUMMARY:Tune-It: Optimizing Wire Reconfiguration for Sculpture Manufacturi
 ng
DESCRIPTION:Technical Papers\n\nQibing Wu, Zhihao Zhang, Xin Yan, and Fanc
 hao Zhong (Shandong University); Yueze Zhu (University College London (UCL
 )); and Xurong Lu, Runze Xue, Rui Li, Changhe Tu, and Haisen Zhao (Shandon
 g University)\n\nWire sculptures are important in both industrial applicat
 ions and daily life. We introduce a novel fabrication strategy for wire sc
 ulptures with complex geometries by tuning the target shape to a collision
 -free shape for the wire-bending machine and then bending it back to the t
 arget by a human. The key challenge lies in tuning the least number of ben
 ding points, which is formulated as an "Optimizing Wire Reconfiguration" p
 roblem. We first fit the input target wire with consecutive line segments 
 and circular segments to ensure the bending manufacturing constraints for 
 each segment, then generate tuned wire through a bilevel optimization. Thi
 s involves selecting the bending points at the upper level with a beam sea
 rch strategy and determining the specifically tuned angles at the lower le
 vel. We perform a thorough physical evaluation using a DIY wire-bending ma
 chine. The results show the effectiveness of our proposed approach in real
 izing a wide range of intricate and complex wire sculptures.\n\nRegistrati
