Andreas Fabri a14cf913e9 WIP: In Lazy.h we now have a single macro for boost and c++11 thread 2015-09-11 14:54:11 +02:00
Andreas Fabri 220651bc88 Use CGAL_THREAD_LOCAL as thread_local only comes with VC201 2015-09-04 18:09:50 +02:00
Jane Tournois 4cf8655c00 move all the cdt.dual(v) code from Triangulation_2 to Mesh_2 
we do not change the API of Triangulation_2 for now
maybe later, and this version should be easy to keep backward compatible
 2015-05-19 08:54:33 +02:00
Jane Tournois 4cf43198e2 dual(v) returns an OutputIterator that collects rays and segments 
to do so, use the Dispatch_output_iterator

- Constrained Voronoi diagram is now a class that has a pointer to a CDT
as member. We don't need an extra CDT anymore
- update examples
- also update the CDT 2 demo to see Voronoi cells, that are only valid when the
triangulation is Delaunay (constrained or not)
 2014-10-07 15:03:41 +02:00
Jane Tournois 8d87ccf8c2 add a dual(vertex) function to DT2 and CDT2 
- in DT2, it returns the Voronoi cell as a Polygon_2
- in CDT2, it returns the - possibly clipped - "bounded Voronoi cell"
see Seidel1988 or http://hal.inria.fr/docs/00/54/68/79/PDF/centroidal-vd.pdf

also add an example that computes the full BVD

Andreas Fabri b307771892 bug fix for natural_neighbor_coordinates_2 using a small feature in the conflict zone functions of Delaunay_triangulation_2 2013-01-08 12:34:37 +01:00
Sébastien Loriot 59f9e8a778 add constructor from range for 2D Delaunay and Regular triangulation 2012-12-19 17:10:57 +01:00
Sébastien Loriot 6ff851e791 macro renaming 2012-11-02 08:44:08 +00:00
Sébastien Loriot 6da5e9e84d unrecursive version of propagating_flip and propagate_conflicts 
for CDT2 and DT2 using 100 recursive calls before switching to
a local stack in a function.
 2012-10-30 13:16:52 +00:00
Sébastien Loriot cd165546fc Remove all alternatives to propagating_flip to keep one that allow to use the call 
stack for at most 100 recursive calls and switch to a non-recursive function
that uses a local std::stack to emulate the call stack.

Benchmarks show the following results:

7 runs on 10,000,000 random in unit circle points

43.67074 : Old implementation
43.91474 : use stack for 100 first call then non-recursive with stack
44.07075 : use stack for 100 first call then non-recursive with vector
44.57079 : Local vector
45.0068 : Local stack
45.87886 : Local fixed size array
46.3829 : Local "home-made" small vector
53.41534 : Thread-local vector

Marc Glisse a758751485 Remove / comment out unused local typedefs. Fix one place where FT was used instead of RT (homogeneous coordinates, probably never compiled). 2012-07-28 06:21:06 +00:00
Sébastien Loriot 498c0a6e1e Make the insert-by-range function more permissive 
The condition is now to be convertible to the point type, pair<point,info>,...
This was the behavior before the insert-by-range-with-info methods were
introduced.

Laurent Rineau 8f59fd9592 Turn QPL into LGPLv3+ 2012-01-13 16:33:35 +00:00
Sébastien Loriot 59b50cc467 make static variable in remove thread_safe. 
I choose this solution since making the container global variable of
the class penalize classes that do not use remove functions.
The overhead introduced is small (less than 2-3% of the total remove time).

Sébastien Loriot 98ddbf9c7e merge packages Spatial_sorting, Triangulation_2 and Triangulation_3 from branch spatial_sorting-add_info-sloriot 2011-05-24 15:48:31 +00:00

protected by macro CGAL_TRIANGULATION_2_DONT_INSERT_RANGE_OF_POINTS_WITH_INFO
 2011-01-11 07:40:47 +00:00
Sébastien Loriot 5f674516b0 add precondition to dual functions to check that objects are from the triangulation. 2010-12-23 15:55:50 +00:00
Sébastien Loriot 5bde754940 remove warnings 2010-07-15 09:14:09 +00:00
Olivier Devillers 974a5380d0 restore the old removal procedure for removal in Delaunay triangulation 
if degree of removed point is > 7

The fast removal is still effective since the
specialized functions for degrees 3,4,5,6, and 7 are used.

Differences in benchmarks for high degrees between old and new was not
big anyway.

Andreas Fabri 4d5300f583 Finally use ptrdiff_t as return type for insert(beg, end) 2010-06-23 13:29:04 +00:00

Sébastien Loriot 52317dd49f add python script (replace_CGAL_NAMESPACE.py) to replace CGAL_BEGIN_NAMESPACE and CGAL_END_NAMESPACE 
by namespace CGAL { and } //namespace CGAL. in all .h and .cpp files
in a directory.
Apply it to all packages in the trunk
Remove macro definition from the config.h file.

This adds requirements to TriangulationTraits2 concept :
Less_x_2 and Less_y_2 predicates.

Also fixes a few bugs in RT2 (hidden points were sometimes forgotten
in degenerate dimensions.)
