Computing an arrangement of segments with some geometrical and topological guarantees is a critical step in many geometry processing applications. In this paper, we propose a method to efficiently compute arrangements of segments using a strip-based data structure. Thanks to this new data structure, the arrangement computation algorithm can easily be parallelized as the per strip computations CGAL, the Computational Geometry Algorithms Library, 1 is the product of a collaborative effort of several sites in Europe and Israel, aiming to provide a generic and robust, yet efficient, implementation of widely used geometric data structures and algorithms. The halfedge e (and its twin e prime ) correspond to a circular arc that CGAL is an open source software project that provides easy access to efficient and reliable geometric algorithms in the form of a C++ library. CGAL is used in various areas needing geometric computation, such as geographic information systems, computer aided design, molecular biology, medical imaging, computer graphics, and robotics. The class Surface_mesh is an implementation of a halfedge data structure and can be used to represent a polyhedral surface. It is an alternative to the CGAL packages Halfedge Data Structures and 3D Polyhedral Surface.The main difference is that it is indexed based and not pointer based. Additionally, the mechanism for adding information to vertices, halfedges, edges, and faces is much simpler 1 Introduction. A halfedge data structure (abbreviated as HalfedgeDS, or HDS for template parameters) is an edge-centered data structure capable of maintaining incidence information of vertices, edges and faces, for example for planar maps, polyhedra, or other orientable, two-dimensional surfaces embedded in arbitrary dimension.
