What Assertion do you get?

If I had to guess what you have to do in order to make the example work, is to construct the numbers not with double (AKA 12.1) but use a constructor that receives a  numerator and denominator.
Still, I have no idea what is the problem as it should work. I also don't understand why is it different in single document.

My compiler is Visual Studio .net 2003,with CGAL-3.2.1,I build a single document project,program code is as following:

 

/**************************************************************************/

#include <CGAL/Exact_predicates_exact_constructions_kernel.h>
#include <CGAL/Delaunay_triangulation_3.h>

typedef CGAL::Exact_predicates_exact_constructions_kernel  K;
typedef CGAL::Delaunay_triangulation_3<K>                  Delaunay;
typedef Delaunay::Point                                    Point;

 

 Point pa=Point(-12.1,0,1),
       pd=Point(-12.1,12,1),
       pe=Point(-12.1,12,4),
       pf=Point(-12.1,0,4),
       pk=Point(6,0,4),
       pl=Point(6,12,4);
  
 Delaunay DT;

 DT.insert(pa);
 DT.insert(pd);
 DT.insert(pe);
 DT.insert(pf);
 DT.insert(pk);
 DT.insert(pl);

/***************************************************************/

In console application,this code is ok,but in single document project,it may causes an exception,it seems like "Debug Assertion Failed".

If I change the coordinates of point into this:

 

Point pa=Point(-12,0,1),     
      pd=Point(-12,12,1),
      pe=Point(-12,12,4),
      pf=Point(-12,0,4),
      pk=Point(6,0,4),
      pl=Point(6,12,4);

,then it has no problem, 

or,if I keep the coordinates not being changed,but replace "<CGAL/Exact_predicates_exact_constructions_kernel.h>" and "typedef CGAL::Exact_predicates_exact_constructions_kernel  K" with "<CGAL/Exact_predicates_inexact_constructions_kernel.h>" and "typedef CGAL::Exact_predicates_inexact_constructions_kernel  K" respectively,it also runs successfully both in console application and single document project.

 

I am confused by this situation,may someone tell me something about this?

thanks.
