SUMMARY:Fast Determination and Computation of Self-intersections for NURBS
  Surfaces
DESCRIPTION:Kai Li and Xiaohong Jia (State Key Laboratory of Mathematical 
 Sciences, Academy of Mathematics and Systems Science, Chinese Academy of S
 ciences; University of Chinese Academy of Sciences); Falai Chen (Universit
 y of Science and Technology of China); and Kai Li\n\nDetecting surface sel
 f-intersections is crucial for CAD modeling to prevent issues in simulatio
 n and manufacturing. This paper presents an algebraic signature-based algo
 rithm for fast determining self-intersections of NURBS surfaces. This sign
 ature is then recursively cross-used to compute the self-intersection locu
 s, guaranteeing robustness in critical cases including tangency and small 
 loops.\n\nInterest Area: Research & Education\n\nRecording: Livestreamed,
