When manually building a triangulation, we might have inserted vertices but
not yet cells, and thus the dimension is 0 but point() should still work.
This is the case in tet_soup_to_c3t3 for example.

Added Mesh_3_regular_triangulation_3_wrapper
...
This wrapper around Regular_triangulation_3 adds undocumented, straightforward
functions which are required for Mesh_3 because of Periodic_3_mesh_3:
they are functions for which both (periodic and non-periodic) triangulations
have fundamentally different implementations, usually because Periodic_3_mesh_3
does not know the offset of a point and must brute-force check all
possibilities. To allow Periodic_3_mesh_3 to use Mesh_3's files,
each mesh triangulation implements its own version.

Adapted the call to spatial_sort() to handle weighted points
...
Downside: we copy points at each comparison, which is terrible! No noticeable
changes when profiling the construction of a triangulation.
We need this copy because of Lazy kernel: despite construct_point_3 having
const Point_3& construct_point_3_object()(const Point_3&)
the Lazy kernel can return some copies.
Other solutions that were not used:
-- Distinguish the Ouput type of Unary_function_to_property map depending on
the type of Kernel (ugly and not safe)
-- Use Weighted_point_mappers traits (but that blood will not be on my hands)
2017-06-28 10:14:35 +02:00
cd9a908393
Ensured that we call kernel functions with the correct (bare) point type
...
Note that if the type `Point` is already `Point_3`, Construct_point_3 does not
do anything (except in the lazy kernel, but in that case, the running time is
horrible anyway).

Deduce Triangulation_3's point type from the TDS
...
Since we have a distinc vertex_base for regular triangulations and that this
regular vertex base defines a type Point, it is redundant to get the Point
type from the Geom_traits.
This also allows to remove the Weighted_point_mapper trick, and pass more easily
custom point types.

Merge from Mesh_3-improvements-GF

+ some bugfixes (most of them are related to the parallel version)
This version works (sequential and parallel) as long as the following macros are NOT defined:
* CGAL_COMPACT_MESH_VERTEX_CELL
* CGAL_INTRUSIVE_LIST
* FORCE_STRUCTURAL_FILTERING

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.

Corrected a rare race condition.
...
The few bad facets that are created during the "cell refinement" step are treated immediately inside the thread which created them.

Finally, a fully parallel version of the refinement. Not very efficient, though, but the idea was to identify all data races and to protect it using locks, atomics, TLS... Needs some tests now, to check if we didn't miss any rare data race.

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).

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.
