Detailed Description

template<class DelaunayTriangulation3>
class SBL::GT::T_Delaunay_triangulation_extension_3< DelaunayTriangulation3 >::Get_area_of_dual_of_edge

Given the dual of an edge, compute its area.

It uses the Get_dual_of_edge fucntor for storing the dual of the input edge as a polygon, and then compute the area of the polygon. If the polygon is infinite, the infinite value (or a maximal value if no infinite value exists) is returned.

Constructor & Destructor Documentation

Get_area_of_dual_of_edge()

Get_area_of_dual_of_edge ( const DelaunayTriangulation3 &  T )

inline

The functor has to be constructed with a given 3D Delaunay triangulation.

Member Function Documentation

operator()() [1/2]

FT operator() ( const Edge &  edge ) const

inline

Given the dual of an edge, compute its area.

It uses the Get_dual_of_edge fucntor for storing the dual of the input edge as a polygon, and then compute the area of the polygon. If the polygon is infinite, the infinite value (or a maximal value if no infinite value exists) is returned.

Parameters

edge	The input edge for which we want the area of its dual.

operator()() [2/2]

FT operator() ( InputIterator  begin, InputIterator  end  ) const

inline

Compute the cumulated area of the duals of all edges in between [begin, end).

It uses the first functor for computing the area of the dual of each edge.

Precondition

No edge has an infinite dual.
