Jane Tournois 535a50217f avoid iterating twice 2020-03-06 17:11:45 +01:00
Jane Tournois 593489a614 wip smoothing using FMLS 
reorganize code to have smaller functions,
use c++11 for loops on ranges,
constify variables...
 2020-02-28 16:51:00 +01:00
Jane Tournois ad6de49304 and const's and use range iterators in smoothing 
and remove outdated code
 2020-02-28 14:28:20 +01:00
Jane Tournois 1c6d251859 fix conversion warning 2020-02-28 13:45:06 +01:00
Jane Tournois a7b745a446 fix init_c3t3() and the collapse() step 
* the code of collapse() is made simpler because the C3t3 already embeds a lot
of topology information that we do not need to re-test

* init_c3t3() now fixes the dimension() of vertices because it was not always
properly set in the input c3t3

* add counters in the plugin to understand why some collapse of very short edges
fail

Jane Tournois baefa0d307 fix cout 2020-02-28 11:46:53 +01:00
Jane Tournois bb76c17ae5 use FMLS in smoothing, and revert to an older version 
fix compilation with c3t3

this version is buggy and produces nan, I don't know why yet so smoothing is
commented out
 2020-02-14 17:02:59 +01:00
Jane Tournois 2ef615d65d reset smoothing function to its initial version 
and make sure it compiles with C3t3 requirements and a regular triangulation
 2020-02-14 11:32:27 +01:00
Jane Tournois 628b800077 move back to helpers file the functions that are needed by smoothing 2020-02-14 11:31:46 +01:00
Jane Tournois b2686b35cc fix cout 2020-02-13 12:13:10 +01:00
Jane Tournois a7c2de7521 improve/fix collapse step 
the topology_test was too restrictive and now makes better use of the info
stored in the C3t3

this commit also moves collapse-specific code to the corresponding file
(instead of the general "helpers" header)
 2020-02-13 12:12:48 +01:00
Jane Tournois 7f8790332e fix iteration counting 2020-02-13 12:10:52 +01:00
Jane Tournois 8bacd01349 minor cout fix 2020-02-07 16:49:59 +01:00
Jane Tournois d0baa099d0 remove max_si computation, not needed anymore 
also fix the count of c3t3 simplices in init_c3t3
(protected by debug macro anyway)
 2020-02-07 16:49:35 +01:00
Jane Tournois 14b326bbe4 "far points" of Mesh_3 have dimension -1 
deal with those, and keep their dimension "invalid" to be able to detect them
 2020-02-07 15:39:31 +01:00
Jane Tournois 22e07a4a32 factor code 2020-02-07 12:16:28 +01:00

Jane Tournois 707cdae9ed use c++11 for loops 2020-02-07 10:02:38 +01:00
Jane Tournois d345c2fe51 flip_3_to_2 does not break surfaces anymore 
updating the outer hull of the set of modified cells is not enough,
"internal" facets should also be updated
 2020-02-06 17:41:03 +01:00
Jane Tournois 62c390c354 use c++11 for loops, add const when possible, and rename containers 2020-02-06 16:44:23 +01:00
Jane Tournois 83df2cea52 rename is_inside(edge) to is_internal(edge) 
for more readability
 2020-02-06 11:27:07 +01:00
Jane Tournois 9eb178247d remove is_convex(tr) that has become useless 2020-02-06 11:20:41 +01:00
Jane Tournois 74243bae58 fix is_inside(edge) 
by taking care also of facets that are in complex though incident
to the same subdomain on both sides
 2020-02-06 11:19:27 +01:00
Jane Tournois 575f8111c3 remove imaginary stuff, and use CGAL internal named parameters 2020-02-04 17:23:30 +01:00

Jane Tournois fea1bb946f collapse does not break surfaces anymore 2020-02-04 10:39:57 +01:00
Jane Tournois d59ef5021d fix split() step by fixing is_outside(edge) 
- go on removing stuff about imaginary vertices
- after this commit, split() is fixed and collapse() causes holes on the surface
 2020-02-03 16:50:05 +01:00
Jane Tournois 54df59efbb fix surface patch and subdomain indices during split 
all of them should be restored after split, which creates twice as many cells
and is likely to recycle old cells, with their outdated c3t3 indices
 2020-01-31 16:55:05 +01:00
Jane Tournois 2e5174f349 fix binary ofstream 2020-01-30 13:19:35 +01:00
Jane Tournois a791ea131e test the validity of the TDS only 
when the input is a c3t3, the internal triangulation can be Delaunay
or Regular
remeshing it breaks its validity "on purpose", do we should not test
triangulation validity
 2020-01-30 11:13:47 +01:00
Jane Tournois f53639ef83 use new API for named parameters 2020-01-28 17:50:14 +01:00
Jane Tournois d3db64f680 add binary dump 2020-01-28 15:50:57 +00:00
Jane Tournois bb0a407ed0 improve doc 2020-01-28 15:50:57 +00:00
Jane Tournois 69e64e5b0c add the ability to use a C3t3 directly in the remesher 
instead of extracting the triangulation first
 2020-01-28 15:50:57 +00:00
Jane Tournois c01952b98c use Triangulation_3 explicitly to make sure the base class is used 
before that, one could give a DT3 or a RT3 to the remeshing function.
Remeshing would then make the triangulation invalid with respect to the
Delaunay or Regular criterion, though the TDS would remain valid.

Now it is clear that we do not expect nor return anything but a valid T3.
 2020-01-28 15:50:57 +00:00
Jane Tournois b4a3dc181d add facet_is_constrained_map to constrain facets 2020-01-28 15:50:57 +00:00
Jane Tournois abe46686d8 move visitor to a private named parameter 
this way we can use the triangulation output by Mesh_3
in a straightforward manner, without converting it to a
Remeshing_triangulation_3

also make sure that it compiles with the Regular_triangulation
used in the Mesh_3 demo plugin

and fix a doc typo
 2020-01-28 15:50:56 +00:00
Jane Tournois e5dfe077b6 use MeshVertexBase_3 and MeshCellBase_3 
the code uses a C3t3 so let's use the actual vertex base and cell base needed
by C3t3, instead of copied simplified versions

Jane Tournois fb71408aed replace cell_base_with_info by a visitor 
the goal is to let a visitor deal with external cell info
it also simplifies the API
 2020-01-28 15:50:54 +00:00

Jane Tournois 5c0b40f591 remove imaginary cells from the complex once remeshing is done 2020-01-28 15:50:51 +00:00
Jane Tournois 0fb3a44d2e remeshing plugin should use Remeshing_triangulation 
using Mesh_triangulation_3 (which is an enriched Regular_triangulation_3)
compiles, but the calls of tr.is_valid() fail since the triangulation
is not regular anymore after remeshing

we reconvert it back to the demo c3t3 triangulation type anyhow, to be able
to display it, hoping that is_valid() will not be called later on
 2020-01-28 15:50:51 +00:00

- make it work with Regular_triangulation and its Weighted_points
- remove everything which was not needed about Surface_patch_index
(1 is in the complex, 0 is not, and is_in_complex(facet) tests
incident subdomains)
