Refine_edges_for_refine_faces no longer exists. The conflicts zone of a point is calculated by using propagate_conflicts(), from the CDT. For that, Refine_edges uses a special Triangulation_mesher_level_traits_2. - Special_zone is now useless. - That's it: the bug is over!! - Mesh_level no wants a function get_triangulation_traits() that returns a reference to the Triangulation_mesher_level_traits. THAT BREAKS COMPATIBILTY with previous codes. - The special traits class Refine_edges_triangulation_mesher_level_traits_2 has a function to set the current edge. This function is used to pass the edge to it, so that get_conflicts_zone() can work. 18 October 2004 Laurent Rineau - Conforming_Delaunay_triangulation_maker_2 renamed to Triangulation_conformer_2. - Update of the documentation. Thanks to Michel Hoffman for his review of the specifications 17 October 2004 Laurent Rineau - Attempt to fix remaining bug: the list of faces modified by the insertion of a point on a segment is not the conflicts zone of the point. remove_constrained_edge() and insert_constraint() flip some faces. I have added a class Refine_edges_for_refine_faces that handles a special member special_zone (bad name) which is a set of faces. do_before_conflict() and do_after_insertion() deal with functions remove_constrained_edge() and insert_contraint() and fill the set special_zone. The visitor Refine_edges_visitor uses this set to remove those faces from bad_faces in after_insertion() (before the two sub-segments are added back by Refine_edges::do_after_insertion(). - However, this attempt fails! Seems that adding back the two subconstraints intersects some other constrained edges already in the triangulation. 12 October 2004 Laurent Rineau - Added parents and names to every layers, so that Qt releases the memory. - Added debugging functions in Delaunay_mesher_2, and new debugging layers and buttons tools into demo/Mesh_2/mesh_demo. These functions are not documented. - CGAL::Mesh_2::Refine_edges now has Tr::Edge has Element type. It decreases number of calls to Tr::is_edge(). - Removed debugging outputs to std::cerr. - The step by step demo now display the edge of the face that will be refined. - Modified Mesh_2::Clusters::get_cluster and Mesh_2::Clusters::update_clusters to fix a bug in debugging functions (can we call that a "meta-bug"?). - Added a function check_bad_faces() in Refine_faces. For the moment, it checks that no bad face has three collinear vertices. It is used in a CGAL_expensive_assertion. 6 October 2004 Laurent Rineau - Patch for gcc-3.4 29 September 2004 Laurent Rineau - New code - New layers in mesh_demo 30 August 2004 Laurent Rineau - New specifications. 17 August 2004 Laurent Rineau - Use namespace CGAL instead of CGAL_NAMESPACE_BEGIN/END. - Insertion in an edge now reinstert the two sub-constraints, instead of using insert with Locate_type==EDGE. - Boost iterators have changed. 09 August 2004 Andreas Fabri Removed semicolons after closing parenthesis of functions, as they make problems for SunProCC 22 July 2004 Laurent Rineau - patch a bug in Delaunay_mesh_2: virtual_insert_in_the_edge was forcing the insertion of a point on a EDGE. 4 July 2004 Andreas Fabri - In Delaunay_mesh_2: Removed const& on an object in a stack that gets popped before it gets used 1 July 2004 Laurent Rineau - Added Extras in Delaunay_mesh_2 too. 28 June 2004 Laurent Rineau - Move mark_facets functions from Delaunay_mesh_2 to Conforming_Delaunay_triangulation_2. - Added a sort of hooks, through a template parameter "Extras", in Conforming_Delaunay_triangulation_2. There is a default template argument that does nothing. These hooks help doing actions when points are inserted. Used in the package Mesh_3. 17 May 2004 Menelaos Karavelas - replaced Point by Point_2 in the demo in order to resolve clash with the Mac version of Qt 6 May 2000 Laurent Rineau - workaround for CC-5.xx, in include/CGAL/Delaunay_mesh_2.h 3 April 2004 Sylvain Pion - Regenerate demo/example makefiles to remove debug options, which makes PGCC pass.
