Ver 4.1 (25 August 1999) readded file CGAL/IO/triangulation_Window_stream.h for backward compatibility. Debugged the example "Triangulation with colored faces" of the manual. Add this example (colored_face.C) in examples/Triangulation. Ver 4.0 (18 August 1999) A new version of triangulation based on a new version of the triangulation data structure with a more coherent representation of degenerate 0-dimensional and 1-dimensional triangulations. From the user point of view this new version should mostly achieved backward compatibility. The main changes concern the iterators on the faces, edges and vertices of the triangulation. They now come with two flavours : the "Finite" iterators iterate only on finite features while the "All" iterators iterate on all (finite or infinite) features of the triangulation. Old iterator types and functions are still present for backward compatibility. Ver 3.25 (5 August 1999) Make a few modifications required by MIPSPRO 7.3 : added a few typedefs in derived class added using std in testsuite Ver 3.24 (9 July 1999) Make the test suite programs systematically tests Homogeneous and Cartesin points using default Euclidean traits class. Corrected the include files. Commented the test of duality which yields a compiler internal error with eg++. Ver 3.23 (6 July 1999) Change number types definition in testsuite to adapt to Gmpz or not Gmpz Ver 3.22 (2 July 1999) Change number types in testsuite to Leda integer and Quotient because Gmpz does not compile on visual C++. Change class Weighted_point_2 to Weight_Point Ver 3.21 (24 June 1999) Distance_2.h and Pointer.h cleaned by Sylvain Ver 3.20 (22 Juin 1999) Added systenatically the argument verbose and levels to is_valid() functions to avoid warning Rewrite the compare() member function of Distance_2 to use the kernel's predicate Suppress the name of unused argument in constructor of Distance_2 (to avoid) warning Ver 3.19 forgotten number, sorry Ver 3.18 (21 Juin 99) Separate into subdirectory predicates, the kernel-like predicates used in regular triangulations. Added a test for regular triangulation with homogeneous coordinates in the testsuite. Ver 3.17 (28 Mai 99) added Point as value_type of Triangulation to get a back_inserter Ver 3.16 (28 Mai 99) include .gif files in doc_tex for figures in html manual Ver 3.15 (21 Mai 99) add a makefile to examples Ver 3.14 (17 Mai 99) same as 3.13 Ver 3.13 (14 Mai 99) corrected a few typos in the doc Ver 3.12 (12 Mai 99) idem as 3.12 but without a few parasite files Ver 3.11 (12 Mai 99) corrected a few typos in the doc Ver 3.10 (12 Mai 99) cleaned some file : Triangulation_2.h Delaunay_triangulation_2.h added set_ascii to input/ouput tests (for MIPS compiler) suppress one of the creator of V2p_adaptor in testsuite (for MIPS compiler) Ver 3.9 (6 Mai 99) Fixed some bugs in Triangulation_euclidian_traits_xy_3.h Triangulation_euclidian_traits_xz_3.h Triangulation_euclidian_traits_yz_3.h Ver 3.8 (1 Mai 99) fixed some bugs related to MIPS CC after CGAL Meeting in Zurich Ver 3.7 (18 April 99) fixed a small bug related to g++ 2.8.1 (std:: versus CGAL_STD) Ver 3.6 (14 April 99) fixed a bug Make the testsuite run with g++ 2.8.1. However the problen of compare() is not quite settled. The test suite runs with g++ 2.8.1 because it uses either a special test_traits which does not use compare() or the euclidean traits with gmpz arithmetic. The examples do not run because they use euclidean traits with double and then the clash of compare() appears Ver 3.5 (9 April 99) namespaces introduced in examples and demos Ver 3.4 (8 april 99) reactiveated the short names for egcs compiler. No more problems with long names did not correct the bug with CGAL_triangulation_assertion (see previous) Ver 3.3 (31 March 99) Correced a few bugs related to preconditions Remains one bug with precondition in Constrained_triangulation_sweep ...Etc (had to comment a line CGAL_triangulation_assertion(false) in a subclass Remains a problem with longnames #define is not convenient with namespaces The bug in circumcenter has been fixed (a problem of number type) Ver 3.2 (27 March 99) A few bugs related to namespace corrected Class Triangulation_line_face_circulator is no longer a subclass of Triangulation It remains a bug to be fixed in circumcenter.... Ver 3.1 (March 99, the 11th) Fixed bugs related to namespaces Ver 3.0 (Feb 99) intoduction of namespaces and new header files Ver 2.10 (Janv. 99) Corrected a few details. Ver 2.9 (Jan 99) Corrected a few small details related to warning "unused variable ..." when compiling without preconditions ans warning "possibly uninitialised variable" when compiling with -O2 Ver 2.8 (Dec 98) Added #include CGAL/Triangulation_short_names_2.h to some files where it was missing to make it hidden from the user Fixed a bug related with default parameter and the previous move of function definitions. Ver 2.7 (Dec 98) Change the implementation of cw() and ccw(). Ver 2.6 (Dec 98) Change the names of some (dummy) template parameter in Constrained Triangulation to make test_suite compile with CC Put the definition of complicated function outside class definition to prevent them from being inlined. Ver 2.5 (Dec 98) Change template parameters because CC does not support typename in parameter type declaration. Changed cgal_test to suppress the test of test_constrained_triangulation_2.C which does not compile on CC Ver 2.4 (Nov 98) Added some test for constrained Triangulations Fixed a few bugs in the test suite. Ver 2.1 (Oct 98) Added some missing header files. Fixed a small bug in increment decrement operators of Line_face_circulator Added a demo for triangulations and Delaunay triangulations and examples. There is still no demo, nor examples, nor testsuite for constrained and regular triangulations (to come soon). The dual functions (asking for Voronoi dual) dont work with the terrain traits class (CGAL_Triangulation_euclidean_traits_xy_3) and the like. Ver 2.0 (Sep 1998) A new version of the triangulation package. The triangulation classes are now implemented along a three levels structure analog to the scheme used in the polyhedron package and in the planar map package. From the user point of view, the main changes reside in the following fact : the triangulation classes (CGAL_Triangulation_2, CGAL_Delaunay_triangulation_2, CGAL_Constrained_triangulation_2 etc.) are now templated with two parameters (a geometric traits class and triangulation data structure class). The test_suite concerns only the classes CGAL_Triangulation_2 and CGAL_Delaunay_triangulation_2. The other triangulation classes CGAL_Regular_triangulation_2 and CGAL_Constrained_triangulation_2 have not yet been thoroughly tested. Ver 1.23 (Jul 1998) - removed warning (count not used) in example/Triangulation/example.C - removed pointer chapter from the documentation - added include in triangulation_print_OFF.h - added examples to the documentation and to the demo subdirectory Ver 1.22 (Jul 1998) - examples/points: added compare to Euclidean_2, and fixed CGAL_orientationC2 - Eliminated some warnings in Triangulation_2.h(1968)::clear(), and Triangulation_face_iterator.h(150) - accelerated test suite by compacting into two files tst2.C and tst3.C Ver 1.21 (25 Jun 1998) - Updated documentation, include files were wrong - added typename in triangulation_print_OFF.h Ver 1.20 (23 Jun 1998) - changed CGAL_orientation(FT ...) to CGAL_orientationC2(FT ...) in euclidean_traits_*_3 [due to a change in C2 package] - changed ==(Point,Point) to traits().compare(Point,Point) This is due to the comparison of points not being the same as the == operator, e.g. for Euclidean_traits_3 (== checks x,y,z coordinates, but triangulation expects only x and y) - re-added copy constructor to CGAL_Pointer Ver 1.19 (19 Jun 1998) - added value_type to allow back_inserter(Triangulation &) - changed doc for bug in example files and added include directives - reformatted doc completely, so that it is nicer. Ver 1.18 (30 Apr 1998) - added demo/ to package (was not present as a mistake) Ver 1.17 (21 Apr 1998) - added #include in Triangulation_euclidean_traits_[xyz]*_3.h which made the test suite failed on tst27, tst37 and tst39 - add Delaunay::dual(Face), dual(edge) - corrected bug in Face::remove() - added types Line, Ray, Direction to traits classes - added copy constructor to CGAL_Pointer - moved back test/ExamplesTriangulation into examples/Triangulation - fixed examples so that they return 0 (and the test suite works) - added demo/ to package - added Inventor_stream.h into demos, so that points3D can compile - added two demos (voronoi and crust) Ver 1.16 (11 Mar 1998) - added handles in Triangulation_euclidean_traits_[xyz]*_3.h - changed #include's in Triangulation_euclidean_traits_[xyz]*_3.h - moved examples/Triangulation into test/ExamplesTriangulation - moved doc_tex/basic/* into doc_tex/basic/Triangulation (for Geert-Jan's scripts) - edited documentation Ver 1.15 (26 Feb 1998) - fixed the _xy euclidean traits classes and tst27, tst37 - removed the input in examples, so that they can be run in the testsuite Ver 1.14 (25 Feb 1998) - introduced separation between demo and examples - fixed the examples Ver 1.13 (17 Feb 1998) - added operator<<(..., Constrained_Triangulation ...) - added documentation in the new format (doc_tex/basic) - added documentation in html format (doc_html/basic/Triangulation) Ver 1.12 (12 Feb 1998) - modified CGAL_CFG_ flags - added typenames, CGAL_NULL_TEMPLATE_ARGS, and other compiler helps - added leda_color (for LEDA-3.6) - corrected a few bugs and fixed the test suite - straightened for g++ 2.8.0 - There still is a bug with Constrained_triangulation, we're working on it. For now, we release the code, the documentation, and the examples, but it is not yet in the test suite. Ver 1.11 (19 Dec 1997) - CGAL_Pointer<>::pointer() renamed to ptr() to avoid name clash with typedef T* CGAL_Bidirectional_circulator_base::pointer - Handles introduced in class Triangulation_2 - class Triangulation_2, Delaunay_triangulation_2 - traits classes Euclidean_traits_2, Euclidean_traits_xy_3, yz_3, and xz_3 CONTENTS: description.txt long_description.txt doc_ps/ contains all the documentation (postscript) triangulation.ps pointer.ps include/CGAL: contains the following files Constrained_triangulation_2.h Constrained_triangulation_face.h Constrained_triangulation_sweep.h Constrained_triangulation_traits_2.h Constrained_triangulation_vertex.h Triangulation_euclidean_traits_xy_3.h Triangulation_euclidean_traits_yz_3.h Triangulation_euclidean_traits_xz_3.h Pointer.h Delaunay_triangulation_2.h Distance_2.h Triangulation_2.h Triangulation_2_edge_iterator.h Triangulation_2_face_iterator.h Triangulation_2_vertex_iterator.h Triangulation_edge_circulator.h Triangulation_euclidean_traits_2.h Triangulation_face.h Triangulation_face_circulator.h Triangulation_vertex.h Triangulation_vertex_circulator.h triangulation_assertions.h Triangulation_euclidean_traits_3.h examples/Triangulation contains the following examples: points.C example.C demo/Triangulation contains the following examples: constraint.C demo.C lfc.C points3D.C test/Triangulation/ contains the test suite for the triangulation
