Mael Rouxel-Labbé a935682a82 (Re-)introduce Compact_simplicial_mesh_cell_base_3 
Formerly known as Simplicial_mesh_cell_base_3, this cell base
is more efficient in memory, but cannot inherit a base.

Mael Rouxel-Labbé 3ad1825359 Fix not being able to Rebind multiple time SMDS_3 / Tet Remesh Vb/Cb 
If you have the following construct:

  class V : public Vb;

  class V_base
  {
    struct Rebind --> V;
  }

then you cannot rebind twice. More vicious, if Vb
can rebind twice multiple times (e.g. it's a T3 Vb),
then it'll silently drop V in the stack, and rebind
only up to the rebound Vb!

Rebinding multiple times happens for example in
Triangulation_hierarchy_3 (Delaunay_triangulation_3
with Fast_locate).

Mael Rouxel-Labbé c0d0c0d01f Fix API of Remeshing_vertex_base_3: 
It needs only to document a traits and a vertex base, not expose
index types as these are relevant to the Simplicial_vertex_base_3
class, which is not the systematic base.

It is a model of RemeshingVertexBase_3, not MeshVertexBase_3

The base needs to be a model of SimplicialVertexBase_3, not
TriangulationCellBase_3

Use the proper Rebind mechanism like the other vertex/cell classes
 2023-07-19 22:42:21 +02:00
Mael Rouxel-Labbé 50fa1ee4de Various fixes for Remeshing_cell_base_3: 
- Restore its correct API (as in CGAL 5.5): two templates, a traits,
and a cell base.
- It is not a model of SimplicialMeshCellBase_3, but of RemeshingCellBase_3
- It should not hardcode an inheritance to Simplicial_cell_base_3,
but take it as a template paramter's default value.
- Use FT instead of hardcoding 'double'

Jane Tournois a90488fce5 fix init_c3t3 for internal C3t3 
the dimensions stored in vertices are made consistent by scanning
the triangulation/subdomains/patches/features/corners, in this order.
Dimensions are tagged like that : all have dimension 3,
- then surface vertices are overridden with dimension 2,
- feature vertices overridden with dimension 1,
- corner vertices overridden with dimension 0.

Mael Rouxel-Labbé 590ddf8015 Various fixes for pmaps: 
- Use `value_type` when the returned type is not a reference
- Enforce `reference = value_type` if the returned type is not
  a reference (to avoid `typename PM::reference r = get(m, k)`,
  which will take a ref to a temporary if the `reference`
  typedef is an actualy reference)
- Do not use `put_get_helper` if the property map is not a `lvalue`
  **mutable** property map: the `put()` is `map[k] = v`, which
  is broken if `operator[]` does not return a reference
- The concept `boost::lvalue_property_map_tag` requires `operator[](key)`,
  not a reference in `get(map, key)`. You can have a readable property map
  returning a reference through its `get(map, key)`, but if there is
  no `operator[]`, it's just a `boost::readable_property_map_tag`
- Some const correctness to avoid copying maps with state
  or heavy keys in `get(map, key)` / `put(map, key, value)`
- Base the category of a wrapping pmap on what it offers instead
  of just forwarding the base property map's category
- Tried to do something like mutable lvalue pmap:
  * `value_type& operator[](key&)`
  * `ref get(map, const key&)`
  * `put(map, const key&, const value_type&)`
  and non-mutable lvalue pmap:
  * `const value_type& operator[](const key&)`
  * `ref get(map, const key&)`
  but not everything fits properly...

it was causing stack overflow on some models
 2020-04-01 07:17:08 +02:00
Jane Tournois 3310ef054d disable smoothing on sharp edges for now 
reprojection does projection on incident patches successively,
and this tends to smooth the shape of complex polylines, though
this is not desired

it seems that 1d smoothing does not really improve the quality nor
complexity of the output mesh, so let's disable it for now

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

 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.
