Mael Rouxel-Labbé 4e33192074 Fixed get_offset_location's second version 2017-06-22 16:02:37 +02:00
Mael Rouxel-Labbé dc8e2a62d5 Minor P3T3 doc changes 2017-06-22 16:02:00 +02:00
Mael Rouxel-Labbé d9c3ec76ad Reworked dual(Cell_handle) and introduced canonical_dual(Cell_handle) 
-- canonical_dual() is what the old dual() function was: returns the
   representation of the dual of the cell handle that is in the domain
-- dual() returns the 'true' dual of the cell handle, which might be out of
   the canonical domain.

The point is that P3M3 must return the 'true' dual to have no issue with the
conflict assertions of Mesh_3, and not a canonicalized dual !

Mael Rouxel-Labbé a8336f39ec Minor misc changes 2017-06-22 15:52:43 +02:00
Mael Rouxel-Labbé 956b1f6fc0 Introduced robust_canonicalize_point() 
This is a way to handle points that are epsilon-close to the boundary yet still
outside. This might create numerical issue such that the point + any offset
does not fall into the domain (due to -epsilon + 1 ~= 1)

The numerical issue is detected when the offset is computed and we snap the
point to the domain.

This is done for P3M3 only (not P3T3: people should give proper input points!)

Mael Rouxel-Labbé fe14379106 P3M3 now use the new robust traits 2017-06-22 15:36:02 +02:00
Mael Rouxel-Labbé ea5a063db8 Added new traits class: Robust_peroidic_weighted_circumcenter_traits_3 
The purpose of that class is somewhat similar to Robust_weighed_circum...etc.:
it aims to provide robust circumcenter computations.

This is the parallel version that switches to exact if the circumcenter is
not in the (smallest) power sphere of the points.

The accuracy issue comes from the use of construct_point_3 with offsets.
Consequently, this class only overrides the versions with offsets.
The other robust class should be used for non-offset versions.

Mael Rouxel-Labbé 1518ef12f2 Removed Mesh_3/test/Mesh_3/test_backward_compatibility.cpp 
The concepts MeshFacetCriteria_3 and MeshCellCriteria_3 have been updated with
a breaking change on their operator() (the triangulation must be passed
as additional parameter).

Mael Rouxel-Labbé 4019425b24 Cleaned off periodic criteria in P3M3/doc 
Well, that's a very empty reference manual now...

Mael Rouxel-Labbé 4c636bbd1c Remove all criteria-related classes from P3M3 
They are now obsolete: we can simply use Mesh_3's
 2017-06-19 16:24:23 +02:00
Mael Rouxel-Labbé 65ef142bff P3M3 now uses Mesh_3 criteria 2017-06-19 16:00:38 +02:00
Mael Rouxel-Labbé 6bb260c954 Document Mesh_3 criteria change (see dd5cd9a) 2017-06-19 15:55:15 +02:00
Mael Rouxel-Labbé 1761ec3294 Mesh_3 criteria is_bad() now additionally takes the triangulation as parameter 
Instead of calling Criteria(element), one must now call Criteria(tr, element).

The idea is that the triangulation should be responsible of geometric data
while elements only handle connectivity (using ids for example).
This is already the case for Periodic_3_mesh_3 which must obtain
"true" geometric information through the (periodic) triangulation class's
methods.

These changes are transparent for Mesh_3 but allow Periodic_3_mesh_3 to use
Mesh_3's criteria.

Mael Rouxel-Labbé 56ead308d4 Added an example of Cartesian_converter specialization for Lazy_alpha_NT 
Needed due to the weird point type that Projection traits use
 2017-06-15 10:34:15 +02:00
Mael Rouxel-Labbé 8e6b834c90 Modified the way weird point types are handled when ExactAlphaComparisonTag=true 
Instead of requiring an implicit conversion, we require that Cartesian_converter
can convert from Traits::Point_23 to Exact_kernel::Point_23

Also it will not compile (static_assert) if this functor is not provided instead
of silently defaulting to ExactAlphaComparisingTag = false
 2017-06-15 10:34:15 +02:00
Mael Rouxel-Labbé 7da382a285 Added new class: Has_conversion 
Used to check whether a Kernel converter (either Cartesian_converter or
Homogeneous_converter) provides the necessary functor T1 operator()(T2)
