SUMMARY:Discovering Folding Lines for Surface Compression
DESCRIPTION:Toshiki Aoki (Massachusetts Institute of Technology), Tomohiro
  Tachi (The University of Tokyo), and Mina Konakovic Lukovic (Massachusett
 s Institute of Technology)\n\nThe miniaturization of shell structures pres
 ents a versatile and complex challenge, bridging geometry with diverse pra
 ctical applications. In this paper, we introduce a novel approach for comp
 uting origami crease patterns to compress arbitrary 3D shell objects. Firs
 t, we employ the adapted Material Point Method (MPM) to simulate the compr
 ession of a target surface and obtain an initial folded configuration. Sin
 ce MPM produces overly smooth curved surfaces, their crease patterns are u
 nsuitable for practical origami fabrication. We then propose a novel Foldi
 ng Line Extraction (FLE) method that optimizes these smoothed surfaces to 
 extract folding lines that achieve the target compression with minimal def
 ormation and stretching outside the crease lines. This method produces smo
 oth curved folding lines. \nFabrication and experimental validation of the
  extracted patterns demonstrate their effectiveness and applicability in r
 eal-world scenarios.\n\nRegistration Category: Full Access, Full Access Su
