Robust Containment Queries over Collections of Trimmed NURBS Surfaces via Generalized Winding Numbers
SessionWinding Numbers & Surface Representations
DescriptionWe introduce an accurate and precise generalized winding number method for trimmed NURBS patches based on integrating along boundary curves. For points near a patch, we add a correction term determined via line-surface intersections. The method enables robust inside-outside containment queries that respect curved features in complex CAD models.
