Spatially Accelerated Winding Numbers for Curved Geometry
Jacob Spainhour, Brad Whitlock, Kenneth Weiss
The generalized winding number (GWN) is a scalar field that supports robust containment queries on curved geometry, including non-watertight, overlapping, and nested boundary repre…

Robust Containment Queries over Collections of Trimmed NURBS Surfaces via Generalized Winding Numbers
Jacob Spainhour, Kenneth Weiss
We propose a containment query that is robust to the watertightness of regions bound by trimmed NURBS surfaces, as this property is difficult to guarantee for in-the-wild CAD model…
