CGAL 4.3 - 2D Boolean Operations on Nef Polygons Embedded on the Sphere
|
The class Qt_widget_Nef_S2 uses the OpenGL interface of Qt in order to display a Nef_polyhedron_S2 | |
An instance of data type Nef_polyhedron_S2<Traits> is a subset of the sphere \( S_2\) that is the result of forming complements and intersections starting from a finite set H of halfspaces bounded by a plane containing the origin | |
| Figures figureNefS2SVertexIncidences and figureNefS2SHalfloopIncidences illustrate the incidences of an sface | |
The type SFace_cycle_iterator iterates over a list of Object_handles | |
| A shalfedge is a great arc on a sphere map | |
| A sloop is a great circle on a sphere | |
An object c of type Sphere_circle is an oriented great circle on the surface of a unit sphere | |
An object p of type Sphere_point<R> is a point on the surface of a unit sphere | |
An object s of type Sphere_segment is a segment in the surface of a unit sphere that is part of a great circle trough the origin | |
| Figure figureNefS2SVertexIncidences illustrates the incidence of a svertex on a sphere map |
