Fast Determination and Computation of Self-intersections for NURBS Surfaces
SessionLightning Fast Geometry
DescriptionDetecting surface self-intersections is crucial for CAD modeling to prevent issues in simulation and manufacturing. This paper presents an algebraic signature-based algorithm for fast determining self-intersections of NURBS surfaces. This signature is then recursively cross-used to compute the self-intersection locus, guaranteeing robustness in critical cases including tangency and small loops.
