Class and Concept List

Here is the list of all concepts and classes of this package. Classes are inside the namespace CGAL. Concepts are in the global namespace.

[detail level 12]

▼NArrDirectionalTraits	The namespace containing concepts specific to 2D Boolean Set Operations
CAreMergeable_2
CCompareEndpointsXy_2
CConstructOpposite_2
CIntersect_2
CMerge_2
CSplit_2
▼NCGAL
CGeneral_polygon_2	The class General_polygon_2 models the concept GeneralPolygon_2
CGeneral_polygon_set_2	An object of the General_polygon_set_2 class-template represents a point set in the plane bounded by \( x\) monotone curves
CGps_circle_segment_traits_2	The traits class Gps_circle_segment_traits_2 models the GeneralPolygonSetTraits_2 concept
CGps_default_dcel	The default DCEL class template used by the General_polygon_set_2 and General_polygon_with_holes_2 class templates
CGps_face_base	An instance of this template serves as a basis type for any face record of the DCEL class used by instances of the General_polygon_set_2 and General_polygon_with_holes_2 class templates
CGps_halfedge_base	An instance of this template serves as a basis type for any halfedge record of the DCEL class used by instances of the General_polygon_set_2 and General_polygon_with_holes_2 class templates
CGps_segment_traits_2
CGps_traits_2	The traits class Gps_traits_2 models the concept GeneralPolygonSetTraits_2
CGraphics_scene_options_polygon_set_2	The class Graphics_scene_options_polygon_set_2 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
CPolygon_set_2	The class Polygon_set_2 represents sets of linear polygons with holes
CArrangementDirectionalXMonotoneTraits_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 ArrangementXMonotoneTraits_2 is only required to have a left (lexicographically smaller) endpoint and a right endpoint. If the traits class is also a model of ArrangementDirectionalXMonotoneTraits_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
CGeneralPolygon_2
CGeneralPolygonSetDcel	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
CGeneralPolygonSetDcelFace	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
CGeneralPolygonSetDcelHalfedge	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
CGeneralPolygonSetTraits_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
CGpsTraitsGeneralPolygon_2	A model of this concept represents a simple general polygon
CGpsTraitsGeneralPolygonWithHoles_2	A model of this concept represents a general polygon with holes
CGraphicsSceneOptionsPolygonSet2	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
