The class Kinetic::Delaunay_triangulation_3<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. In addition, as an optimisation, you can turn on and off whether it is currently maintaining its certificates. This allows a large number of changes to the underlying points to be made at one time without recomputing the certificates each time a single point changes.
Note that the Delaunay triangulation is fully dynamic as it tracks points added to and removed from the Kinetic::ActiveObjectsTable.
The class Kinetic::Qt_triangulation_3<Traits>, included as part of the demo code, displays a kinetic Delaunay triangulation in three dimensions using the Coin library.
The optional Visitor template argument is a model of Kinetic::DelaunayTriangulationVisitor_3 and can be used to monitor changes in the kinetic data structure.
The optional Triangulation template argument must be a model of a CGAL::DelaunayTriangulation_3 which uses Traits::Default_instantaneous_kernel as its geometric traits and has Kinetic::Delaunay_triangulation_cell_base_3<Traits, Base> a the cell type.

Maintain the Delaunay triangulation of the points in tr.active_points_3_handle().


 Access the triangulation that is maintained. 

 This method returns true if the Kinetic::Delaunay_triangulation_3<Traits, Visitor, Triangulation> is currently maintaining certificates for a Delaunay triangulation. 

 
This method allows you to control whether the triangulation is maintaining certificates.
