CGAL::Kinetic::Delaunay_triangulation_2<Traits, Visitor, Triangulation>

Definition

The class Kinetic::Delaunay_triangulation_2<Traits, Visitor, Triangulation> maintains a Delaunay triangulation on top of the points contained in a Kinetic::ActiveObjectsTable. It has one main method of interest, triangulation(), which returns the triangulation it is maintaining.

The class Kinetic::Qt_triangulation_2<KineticTriangulation_2, QtWidget_2, QtMovingPoints_2> displays a kinetic Delaunay triangulation using the Qt widget.

This class is a good example of a simple, but non-trivial, kinetic data structure.

The Triangulation template parameter must be a model of CGAL::Delaunay_triangulation_2<Traits, Tds> which uses Traits::Instantaneous_kernel as its geometric traits and a Tds whose face inherits from Kinetic::Delaunay_triangulation_face_base_2<Traits, Base>.

The optional Visitor parameter takes a model of Kinetic::DelaunayTriangulationVisitor2. Methods on this object will be called whenever the triangulation changes.
