Sylvain Pion 92257a66a2 Add constructors of Vector_? taking mixed types (e.g. int, double). 
Spotted by the Min_ellipse_2 test-suite.  Regression due to my latest changes
to store Vectors in Points.

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 b0f2c77fdc Remove casts to Oriented_side. 
They are useless since we merged the various enum types.
 2008-04-09 12:35:10 +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...

Sylvain Pion 57d48d8d83 Replace useless forwarding function orientationH2() by sign_of_determinant3x3(). 2008-03-21 08:45:04 +00:00
Sylvain Pion c825d8c774 Remove some useless enum_cast<>. 
Optimize some sign(a*b) to sign(a)*sign(b).

Andreas Fabri 0290ab619d removed unused parameters 2007-03-17 09:50:18 +00:00
Sylvain Pion 370e6a1695 Move 3D .bbox() to the functors to make Lazy_kernel pass, and enhance the test-suite to test .bbox() 2006-12-27 23:25:54 +00:00
Sylvain Pion fbe285ca94 New predicates : 
compare_squared_distance(Point_[23], Point_[23], FT), with
  CompareSquaredDistance_[23] functors.

Andreas Fabri f5c431bedb fix for min/max problem 2006-08-20 21:18:19 +00:00
Sylvain Pion c206dcd8e1 Fix ambiguities in constructors of PointH?, 
as convertibility between RT<->FT<->int was a problem.
Use enable_if<> and is_convertible<> for this.

Sylvain Pion ed36e763c7 Second part of Return_base_tag changes. 2006-08-16 16:38:49 +00:00
Sylvain Pion 2eb12d7441 - First part of introduction of Return_base_tag workaround for lack 
of "forwarding constructors".
  Quoting some comment in the code:
  "
    This is a simple tag which is used as additional (first) argument in
    some kernel functors, to tell them to return the base (rep) class,
    instead of the main type (e.g. Kernel_base::Point_2 instead
    of Kernel::Point_2).  This is a minor optimization which prevents
    useless copies of the "reps".

    Those functors are only those used in the constructors of the kernel
    types like Point_2, so it's limited.

    The real solution will be to use "forwarding constructors", when they
    will be available in C++.
    In the mean time, this should be a mostly/hopefully internal hack.

Andreas Fabri 12dbb148a9 fixed min/max problem 2006-08-16 14:43:19 +00:00
Sylvain Pion c50783f08f Bad luck: "equi-distant" -> "equidistant" (thanks Andreas). 2006-08-07 16:11:40 +00:00
Sylvain Pion 38853d1b10 - Optimize equi_distant_line() by merging the calls to 
circumcenter() and cross_product().
- Add ctors to Point_[23] and Vector_[23] that take
  int, double, and FT coordinates, instead of only RT.
 2006-08-07 15:57:40 +00:00
Sylvain Pion f4be5b9920 Add overloads of circumcenter() taking only 2 Point_2 (or Point_3), 
that is, the same thing as midpoint(), but with a uniform notation.
Same thing for the corresponding functor.
 2006-08-03 17:07:39 +00:00
Sylvain Pion 9424d0e9d8 Remove some assertions, as they must not pop-up, since they are 
used by Cartesian_converter/Homogeneous_converter, where we
absolutely must not throw.

TODO : find a way to keep the assertion while having the
       converters still work.  (should types come with their
       own conversions, like they all have .bbox() ?)
 2006-08-03 11:29:12 +00:00
Sylvain Pion ea748e53d4 Add new constructor to Iso_rectangle_2(Point_2, Point_2, int). 
The additional dummy "int" specifies that the 2 points are
the lower-left and upper-right corner.  This is more efficient
when one knows they are already in this configuration.

Same thing for Iso_cuboid_3, and the functors.

Use them in Cartesian_converter and Homogeneous_converter.

Sylvain Pion 6ee4e656e7 Add determinant(Vector_2, Vector_2) 
Add determinant(Vector_3, Vector_3, Vector_3)
And corresponding functor.

Sylvain Pion cbd6fc9417 Move .transform() in the 3D user classes. 
Move some functions in the 3D user classes instead of the internal
 rep classes.
