Spatially Accelerated Winding Numbers for Curved Geometry
SessionWinding Numbers & Surface Representations
DescriptionExisting winding number methods for curved geometry, such as SVG and CAD datasets, scale linearly with the number of NURBS primitives. We propose a sublinear approach that leverages a BVH to agglomerate winding number contributions from distant boundary components while maintaining accurate point containment decisions on in-the-wild datasets.
