2D Straight Skeleton and Polygon Offsetting Reference

Fernando Cacciola

This package implements an algorithm to construct a halfedge data structure representing the straight skeleton in the interior of 2D polygons with holes and an algorithm to construct inward offset polygons at any offset distance given a straight skeleton.
