Stéphane Tayeb 8dceee4164 Add include<CGAL/assertions.h> in *_assertion files. 2009-10-07 13:16:13 +00:00
Stéphane Tayeb 770492c1c7 Use new version of script create_assertions.sh to generate *_assertions.h files. 
Diffs are:
 * #undef added
 * in old files, (void)0 is replaced by static_cast<void>(0)
 * in old files, lines as "#  define CGAL_xxx_assertion 1" are added
 * in point_set_processing_assertions.h, surface_mesh_parameterization_assertions.h, surface_reconstruction_points_assertions.h, "|| defined(CGAL_NDEBUG)" is replaced by "|| defined (NDEBUG)"
 * protective macros (if any) are removed
 * included files if any (<CGAL/assertions.h>, <CGAL/trace.h>) are removed

Sylvain Pion a448798082 Remove more EPS files. 2009-09-18 13:25:40 +00:00
Laurent Rineau e896a33ec6 We must either: 
- include <CGAL/config.h>
  - or not use CGAL_BEGIN_NAMESPACE.
I prefer the second option.

Laurent Rineau f097b7a000 Fix the testsuite of compare_dihedral_angle_3. 2009-08-27 08:33:48 +00:00
Laurent Rineau 770f8f85f2 Documentation of revision 51512: 
In Compare_dihedral_angle_3, add the comparison between the dihedral
  angle defined by four points (or three vectors), and a FT. The FT
  represents the cosine of the angle.

Laurent Rineau 4a383b3197 In Compare_dihedral_angle_3, add the comparison between the dihedral angle 
defined by four points (or three vectors), and a FT. The FT represents the

Sylvain Pion 53f5c9679b Add a using directive "using std::array" in namespace CGAL to import either: 
- C++0x's std:array from <array>
- TR1's std::tr1::array from <tr1/array>
- boost::array from <boost/array.hpp>
Motivation : GCC's std::array is faster than boost::array.

Move CGALi:make_array to namespace CGAL.

Sylvain Pion 173ef7c590 Allow propagation of Uncertain-ty in more places, to reduce the number of exceptions. 
- Use K::Bool_type, K::Orientation... instead of bool, CGAL::Orientation...
- More functions around Uncertain<> : make_certain(), extract_singleton(),
                                      possible conversions tightenning.

Many conversions still remain, e.g. for switch and if statements, &&, ||...

 2008-07-12 21:09:38 +00:00
Sylvain Pion 9d7a609ff2 Make assertions trigger an error only for *certain* conditions (using CGAL::certainly()). 
This is useful for interval arithmetic code.
(replay of r44002 with the header order hopefully fixed)
 2008-07-10 21:49:17 +00:00
Sylvain Pion 2b4ebf01f7 Undo r44002 as it's buggy 2008-07-06 20:47:29 +00:00
Sylvain Pion 514a17ad4f Improve the interaction of assertions and interval computations. 
Things like "CGAL_assertion(denominator != 0)" produced assertion failures for no gain.
So now, the assertion is triggered only if the condition is certain, using CGAL::certainly().
That is, change the following in all assertion files :
  ((EX)?(static_cast<void>(0)): ::CGAL::assertion_fail( # EX , __FILE__, __LINE__))
to :
  (CGAL::certainly(EX)?(static_cast<void>(0)): ::CGAL::assertion_fail( # EX , __FILE__, __LINE__))

Sylvain Pion 02e543a294 Add Dimension<T, K> whose nested "value" is the dimension of the ambiant 
space.  A special constant CGAL::Dynamic_dimension (equal to INT_MAX)
indicates the case where the dimension is only known at run time.
 2008-04-11 21:03:22 +00:00
Sylvain Pion aad1552b8a Add Dimension_tag<int dim> to help dispatching functions depending 
on the dimension.

Sylvain Pion ef71559164 Remove the Kernel Concept Archetypes. 2008-04-11 19:26:21 +00:00
Sylvain Pion 1ce5c4a18d Add forgotten documentation for: 
orientation(Vector_2, Vector_2)
  orientation(Vector_3, Vector_3, Vector_3)
 2008-04-11 14:38:32 +00:00
Sylvain Pion 4873e53de2 Move: 
<CGAL/Kernel/Cartesian_coordinate_iterator_2.h>
  <CGAL/Kernel/Cartesian_coordinate_iterator_3.h>
To:
  <CGAL/Filtered_kernel/Cartesian_coordinate_iterator_2.h>
  <CGAL/Filtered_kernel/Cartesian_coordinate_iterator_3.h>
 2008-04-09 18:06:00 +00:00
Sylvain Pion 11bbf3e2de Vector_2 and Vector_3 now also provide a Cartesian_const_iterator. 2008-04-09 17:58:57 +00:00
Sylvain Pion 1d8779b171 Rename the following functions: 
det2x2_by_formula
  det3x3_by_formula
  det4x4_by_formula
  det5x5_by_formula
  det6x6_by_formula
to:
  determinant

How cute...  a name independent of the dimension, and even readable !
 2008-04-09 13:35:34 +00:00
Sylvain Pion b740e90de0 Rename the following functions: 
sign_of_determinant2x2
  sign_of_determinant3x3
  sign_of_determinant4x4
  sign_of_determinant5x5
  sign_of_determinant6x6
to:
  sign_of_determinant

So that we have less dimension-dependent namings, at least internally...
 2008-04-09 12:20:25 +00:00
Sylvain Pion 54648829af Merge <CGAL/functions_on_enums.h> into <CGAL_enum.h>. 
No need to have 2 separately documented headers for that.

Andreas Meyer 20315de571 * replaced CGAL_test_assert with ::assert, instead of CGAL_assertion
