2D Arrangements
Reference Manual

Ron Wein, Efi Fogel, Baruch Zukerman, and Dan Halperin

Given a set of planar curves, the arrangement () is the subdivision of the plane induced by the curves in into maximally connected cells. The cells can be 0-dimensional (vertices), 1-dimensional (edges) or 2-dimensional (faces).

The class Arrangement_2<Traits,Dcel> encapsulates a data structure that maintains arrangements of arbitrary bounded planar curves. It comes with a variety of algorithms that operate on planar arrangement, such as point-location queries and overlay computations, which are implemented as peripheral classes or as free (global) functions.
