Laurent Rineau 72e0a3e677 Fix warnings about signed/unsigned 
The code involved is about TBB.

Clement Jamin 078e89f55f Add the possibility to remove the far points 
The far points are added by the parallel version to reduce the contention
on the infinite vertex

Clement Jamin e07baefb17 Change the way we compute the exact circumcenter when needed 
In some rare cases, we need to switch to exact computation for the circumcenter.
Some code for this computation is now moved from RT3 to Refine_facets.
 2014-04-15 18:54:12 +02:00
Jane Tournois 88666391da introduce weighted_circumcenter() for RegularTriangulationCellBase_3 
weighted_circumcenter() replaces circumcenter() in the regular framework,
which is not a member of TriangulationCellBase_3 anymore.

Triangulation_cell_base_with_circumcenter_3 is deprecated and replaced by:
Delaunay_triangulation_cell_base_with_circumcenter_3
and
Regular_triangulation_cell_base_with_circumcenter_3.

Implement the changes in documentation, Triangulation_3 code and Mesh_3 code.

Clement Jamin fcdf906f06 Option to add temporary points on a far sphere before insertion 
Helps to reduce contention on the infinite vertex
But removing those points in the end takes time
so it's only worth it when points lie on a surface.

Clément Jamin dfbddff185 Bugfixes + some clean-up 2012-05-30 14:49:02 +00:00
Clément Jamin a0a92cdf64 The problem "A facet is not in conflict with its refinement point" (can occur in sequential version too) is now solved => we switch to exact computation (for the dual) when it happens. 
Note: don't try to #define CGAL_MESH_3_DO_NOT_LOCK_INFINITE_VERTEX, it doesn't work yet.

Clément Jamin 4fdf647428 "Re-tabulation" 2012-03-28 08:30:32 +00:00
Clément Jamin da923ba811 Forget about yesterday. There was a studid mutex making the whole thing nearly sequential. 
Anyway, now the refinement of the facets is parallel. The speedup is around 2-3 on a 12-core CPU. Can do better, but at least it shows it's not sequential.
The refinement of the cells is not parallel, yet.
One last thing: the program needs to be restarted between two refinements (should be fixed soon).
 2012-03-23 18:05:24 +00:00
Clément Jamin 4ccf8e0447 First working parallel version. It's not faster than the sequential one, but not slower neither (depends if you're optimistic or not). The good news is that we found all (?) the sections to protect or to make thread-local. 2012-03-22 17:07:03 +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.
