Laurent Rineau 6579b41282 Fix a segfault in Mesh_3. 2008-06-12 15:37:06 +00:00
Laurent Rineau 5bc7e76e17 Add an assertion, that checks if a facet is in conflict with its refinement 
point. It MUST be (otherwise Surface_mesher enters an infinite loop).

If the assertion fails, its "what() string" is a set of debugging
informations.
 2008-06-10 14:06:24 +00:00
Laurent Rineau b5bad15aa7 Fix an old nasty bug: the clipping for segment with a sphere was incorrect! 2008-06-09 14:20:14 +00:00
Laurent Rineau 6990082221 - New macro CGAL_SURFACE_MESHER_DEBUG_IMPLICIT_ORACLE 
- More debug instructions in <CGAL/Surface_mesher/Implicit_surface_oracle_3.h>
 2008-06-09 13:33:37 +00:00
Laurent Rineau e6b1bb3ae2 Put some debugging code between #ifdef/#endif CGAL_SURFACE_MESHER_DEBUG_CRITERIA 2008-06-06 12:28:14 +00:00
Laurent Rineau ddfc10e8e0 Minor changes: 
- Add two const& 
  - Let before_insertion_impl in Surface_mesher_manifold and
    Surface_mesher_regular_edges pass its argument of type Facet to the same
    function in the base class.
 2008-06-06 12:22:22 +00:00
Laurent Rineau 3702d39202 New parameters, that show the superiority of Surface_mesher over 
VTK's marching cube.
 2008-05-29 13:45:47 +00:00
Laurent Rineau 271df19d73 - First version of a VTK vtkImageData to vtkPolyData filter: mesh an 
iso-value in a 3D image.
 2008-05-21 22:16:03 +00:00
Laurent Rineau 4ed2298896 Allow to construct a Gray_level_image_3 from an Image_3. 2008-05-21 22:11:03 +00:00
Laurent Rineau c79aacdc8c Fix the error "error: 'number_of_facets_on_surface' was not declared in 
this scope" in <CGAL/IO/Complex_2_in_triangulation_3_file_writer.h>.
 2008-05-21 16:08:27 +00:00
Laurent Rineau abf246366d - add constness to facets_begin()/facets_end() in c2t3, 
- add more VTK support: output a c2t3 to a vtkPolyData
- add a demo that shows the ability to display a c2t3 in a VTK viewer.
 2008-05-20 11:51:10 +00:00
Laurent Rineau 7002346ca2 Minor change: add a missing const&. 2008-05-12 20:45:09 +00:00
Laurent Rineau 63b39ef1be Quick fix for Mesh_3. is_in_volumes() only affects Mesh_3 2008-05-12 20:43:54 +00:00
Laurent Rineau cab2554766 Minor commit: add a few "const" or "const&". 2008-04-29 13:51:29 +00:00
Laurent Rineau f677dd435d - Commit 43053 was not really a fix for the "set_on_surface" problem. 
- Some piece of meta-programming was needed, actually.
  p.set_on_surface(...) is now called only if the type Point has a
  Set_on_surface nested type.
 2008-04-29 13:50:11 +00:00
Laurent Rineau 4e4f937188 - Tags in cells now use std::bitset instead of the home-made bitset. 
- New tag: is_bad (to reduce the number of calls to Double_map::erase)
 2008-04-29 08:57:30 +00:00
Laurent Rineau 38ebdc41f2 Fix the set_on_surface problem: the present of a tag is tested. 2008-04-29 08:53:50 +00:00
Laurent Rineau 1a55b0a8e3 - Add calls to CGAL::Profiler 
- No longer test the Gabriel criteria for facets.
 2008-04-28 13:02:10 +00:00
Laurent Rineau 6e2224ccf3 Moved to Mesh_2/include/CGAL/Meshes/. 2008-04-25 12:14:32 +00:00
Laurent Rineau 22629c62b3 New directory Mesh_2/include/CGAL/Meshes/ that aggregates several 
non documented files that are common to Mesh_2, Mesh_3 and Surface_mesher.
 2008-04-21 16:07:38 +00:00
Laurent Rineau 9fa4761d86 CGAL::Image_3 is no longer a class template. 
New parameter value_outside, with default = 0.f

That class should be removed in CGAL-3.4, as soon as a better oracle exists
for 3D images.
 2008-04-16 12:36:02 +00:00
Sylvain Pion 1b79e6c94d Use CGAL::midpoint() instead of redoing the computation. 2008-04-11 16:11:47 +00:00
Laurent Rineau 09a919365f Move most of Gray_level_image_3 to a new class <CGAL/Image_3.h>. 2008-04-08 08:59:13 +00:00
Laurent Rineau c6fa89e93c Do not export File_writer_OFF comments to OFF files. 2008-04-08 08:55:43 +00:00
Laurent Rineau 1dccc80b79 Fix the testsuite temporarily, before I break everything again. 2008-04-01 12:55:59 +00:00
Laurent Rineau 00ced538b1 Modifications of C2T3: 
- add a lot of comments arround the face status.
- use explicit variable names in union find, instead of 'i' and 'j'
- add a is_valid() function, that checks that the facets markers are the
  same from both sides, and that the real number of marked facets is
  conform to the cached number (used in the Slivers_exuder),
 2008-03-13 22:13:30 +00:00
Laurent Rineau b60a86e0c7 - Fix a missing header: <stack>) 
- Activate now by default the version of output_surface_facets_to_off()
  that orients the surface.
 2008-03-11 15:11:54 +00:00
Laurent Rineau 5075e30cc5 Fix the color association. 
Points are still indexed by int, but surfaces are now indexed
by a "const QTreeWidgetItem*"! :-)
 2008-02-05 23:44:08 +00:00
Laurent Rineau 16e98803c1 Can now use Surface_mesher with multi-domains. 
In the demo, one can define a list of iso-values.
 2008-02-05 14:46:17 +00:00
Laurent Rineau ba1ef9944b First step to a multi-label oracle: make Implicit_surface_oracle_3 do not 
depend on the type CGAL::Sign.
 2008-01-29 10:14:27 +00:00
Laurent Rineau eafc8f0d11 include/CGAL/ImageIO.h is now back in CGAL 2008-01-28 14:55:52 +00:00
Laurent Rineau d682c43451 Add two files needed by new features of revision r41873: they are model of 
a new concept of point, that stores:
  - the lowest dimension of all psc elements that contain it,
  - the index of the psc elements of lowest dimension that contains it.

Two files:
  include/CGAL/Point_with_psc_localisation.h
  include/CGAL/Weighted_point_with_psc_localisation.h
with bvious names: one is for Delaunay triangulations, and the other is for
regular triangulations.
 2008-01-28 14:13:52 +00:00
Laurent Rineau 83171e4fd8 Deprecated files, never used. They were commited in revision 41880 in order to be backuped in the svn repository. 2008-01-28 13:59:19 +00:00
Laurent Rineau 5c3567e15f Temporarily commit deprecated files. 
They are about to be removed (in revision 41881 actually).
That commit is only for those files to be stored on the subversion
repository (in the history).
 2008-01-28 13:58:16 +00:00
Laurent Rineau ef6d4c019d - edges and facets are now taggued with the index of the PSC element of 
lower dimension that contains them,
- the oracle sets tags in points as well,
- the edges default criteria can now enforce that an edge must have its two
  end points on the same curved edge,
- new facets criteria to enforce a facet to have its three vertices on the
  same surface patch.
- The surface is now pass by const reference to the oracle (that was one
  reason of the  poor performances of the polyhedral oracle!).

ALL THAT CODE WILL NEED A FULL REVIEW BEFORE CGAL-3.4.
 2008-01-28 09:38:18 +00:00
Laurent Rineau 8533dd1589 Change in Surface_mesher::Standard_criteria include/CGAL/Surface_mesher/Standard_criteria.h : 
If a criteria bound is 0, then the criteria is always fullfilled (instead of never fullfilled).
 2008-01-28 09:24:02 +00:00
Laurent Rineau 0b5e91875f Fix compilation with g++-4.3. 2008-01-28 08:57:07 +00:00
Laurent Rineau af1ada7aa1 Use object_cast instead of assign (see revision 40902, 40923, 41482 also). 2008-01-25 15:42:51 +00:00
Laurent Rineau e4e8a9e7d7 Use Triangulation_cell_base_with_circumcenter_3 in the default triangulation for Surface_mesher 2008-01-25 09:18:30 +00:00
Laurent Rineau 42f222c01c - Fix an old and minor bug (from revisions 38635+38306 in a branch, the bug 
was merged in trunk at revision 38638). The image data should be
  deallocated, now.
  Actually, that bug exists since the begin of Gray_level_image_3
  (CGAL-3.2). I thought I fixed it with revision 38306, but I failed to
  correctly fix it.

- Add the possibility to define the interior of the object by f(x)>0,
  instead of f(x)>0. That will be superseeded very soon.
 2008-01-24 13:25:16 +00:00
Laurent Rineau ece2b056d4 Fix compilation error, when CGAL_SURFACE_MESHER_DEBUG_INITIAL_POINTS is 
defined.
I forgot that change in revision 41482.
 2008-01-24 12:54:18 +00:00
Sylvain Pion 8ebd675cf9 Fix protect macro name, it was clashing with another file. 2008-01-14 21:31:05 +00:00
Laurent Rineau 4b2bc78fc4 - use object_cast instead of assign 
- add the typedef Intersection_point, to fix the testsuite.
 2008-01-09 10:35:49 +00:00
Laurent Rineau 9bbe7ad8fb - Use SurfaceMeshTraits::Intersection_point, as the point type embeded in 
the CGAL::Object that is returned by the mesh traits (aka the oracle).
- Use object_cast instead of assign, everywhere.
- Do not ask the oracle about degenerate dual segments.
- Remove more warnings about unused variables (when NDEBUG is defined).
