SUMMARY:Tune-It: Optimizing Wire Reconfiguration for Sculpture Manufacturi
 ng
DESCRIPTION:Qibing Wu, Zhihao Zhang, Xin Yan, and Fanchao Zhong (Shandong 
 University); Yueze Zhu (University College London (UCL)); and Xurong Lu, R
 unze Xue, Rui Li, Changhe Tu, and Haisen Zhao (Shandong University)\n\nWir
 e sculptures are important in both industrial applications and daily life.
  We introduce a novel fabrication strategy for wire sculptures with comple
 x geometries by tuning the target shape to a collision-free shape for the 
 wire-bending machine and then bending it back to the target by a human. Th
 e key challenge lies in tuning the least number of bending points, which i
 s formulated as an "Optimizing Wire Reconfiguration" problem. We first fit
  the input target wire with consecutive line segments and circular segment
 s to ensure the bending manufacturing constraints for each segment, then g
 enerate tuned wire through a bilevel optimization. This involves selecting
  the bending points at the upper level with a beam search strategy and det
 ermining the specifically tuned angles at the lower level. We perform a th
 orough physical evaluation using a DIY wire-bending machine. The results s
 how the effectiveness of our proposed approach in realizing a wide range o
 f intricate and complex wire sculptures.\n\nRegistration Category: Full Ac
