concept | AosDirectionalXMonotoneTraits_2
| This concept refines the basic arrangement \( x\)-monotone traits concept. A model of this concept is able to handle directed \( x\)-monotone curves that intersect in their interior. Namely, an instance of the `X_monotone_curve_2` type defined by a model of the concept `AosXMonotoneTraits_2` is only required to have a left (lexicographically smaller) endpoint and a right endpoint. If the traits class is also a model of `AosDirectionalXMonotoneTraits_2`, the \( x\)-monotone curve is also required to have a direction, namely one of these two endpoint serves as its source and the other as its target.

concept | GeneralPolygonSetDcel
| A doubly-connected edge-list (Dcel for short) data-structure. It consists of three containers of records: vertices \( V\), halfedges \( E\), and faces \( F\). It maintains the incidence relation among them. The halfedges are ordered in pairs sometimes referred to as twins, such that each halfedge pair represent an edge. More...
concept | GeneralPolygonSetDcelFace
| A face record in a Dcel data structure used by the `General_polygon_set_2` and `Polygon_set_2` template classes to represent the underlying internal `Arrangement_2` data structure. More...
concept | GeneralPolygonSetDcelHalfedge
| A halfedge record in a Dcel data structure used by the `General_polygon_set_2` and `Polygon_set_2` template classes to represent the underlying internal `Arrangement_2` data structure. More...
concept | GeneralPolygonSetTraits_2
| This concept defines the minimal set of geometric predicates needed to perform the Boolean-set operations. It refines the directional \( x\)-monotone arrangement-traits concept. In addition to the `Point_2` and `X_monotone_curve_2` types defined in the generalized concept, it defines a type that represents a general polygon and another one that represents general polygon with holes. It also requires operations that operate on these types. More...

concept | GraphicsSceneOptionsPolygonSet2
| The concept `GraphicsSceneOptionsPolygonSet2` defines data and methods used to tune the way that the cells of a `Polygon_set_2` are considered for drawing or to be added into a graphics scene. More...
