Raw Blame History

10 March 2006: Menelaos Karavelas
- unqualified swap of <FT>
- removed workaround for g++ < 3
9 March 2006: Menelaos Karavelas
- changed default background color from yellow to black
- gave the example files some more meaningful names
- capitalized headings in user manual
- attempt to fix sunpro warnings
- "fixed" code when run with a number type that does not
support / and sqrt ("fixed" here means that the code still runs but
operations are no longer exact; the operations that are not exact
are only used for constructions, not for predicates); the issue
came up in the segment Delaunay graph package which uses the
Parabola_2 and Parabola_segment_2 from this package.
8 March 2006: Menelaos Karavelas
- demos now include CGAL/basic.h before testing for Qt; this is essential
due to the recent changes in install_cgal
- changed code in {Hyperbola,Parabola}_segment_2 to please VC8.
17 December 2005: Menelaos Karavelas
- fixed chapter names in doc
30 November 2005: Menelaos Karavelas
- added one more version of the orientation predicate, needed for
locating on edges of the Apollonius graph (addition in
code/predicates/traits and doc).
- fixed broken file inclusion: the error was due to the
renaming/rearranging of the segment Delaunay graph package.
21 November 2005: Menelaos Karavelas
- fixed problem with toolbars under linux. The toolbars stopped being
visible once the menus where added. This has now been fixed.
- added view menu; the user can now choose the background color among
three: white, black, yellow.
6 August 2005: Menelaos Karavelas
- fixed unreachable statement warnings produced by pgCC
- fixed bug in construction of bisector ray
- fixed bug in computation of conflicts: if the query site destroys
everything the edge list is empty, which was not handled correctly.
31 July 2005: Menelaos Karavelas
- fixed wrong assignments of signs to FT in compare_quadratic.h
30 July 2005: Menelaos Karavelas
- fixed "control reaches end of non-void function" warnings in g++ 4.0.0 of
MacOS X Tiger
- reverted MP_Float related change in test_ag_hierarchy_2.C
22 July 2005: Menelaos Karavelas
- fixed problems created with wrong insertion of copyright headers in demo
20 July 2005: Menelaos Karavelas
- added copyright headers in demo files
30 June 2005: Menelaos Karavelas
- added get_conflicts() methods (similar to those in regular and Delaunay
triangulations); need to update the doc and the testsuite also.
26 June 2005: Menelaos Karavelas
- doc: added Triangulation_data_structure type and tds() method; also added
that the Apollonius_graph_2 class is a model of the DelaunayGraph_2 concept.
- doc: added Vertex and Face types in the Apollonius_graph_2 class; fixed
some errors in the definition of the various iterators/circulators.
- AG2 class: almost all combinatorial types are now defined through Agds and
not the triangulation (except the Finite_*_iterator types).
21 June 2005: Menelaos Karavelas
- removed unused code related to homogeneous coordinates/representations
- changed code in traits to minimize function/method calls
- renamed some methods
15 June 2005: Menelaos Karavelas
- added layout widget in demo including a label; messages about the actions
taken are now printed on the label.
- added file menu in demo; used for file I/O.
- added about boxes in demo.
13 June 2005: Menelaos Karavelas
- changed messages/captions of the file toolbar of the demo program
4 June 2005: Menelaos Karavelas
- Apollonius_graph_2 and Apollonius_graph_hierarchy_2: added methods file_input
and file_output that read and write from and to a file. The data written
consists of the visible and hidden sites and the triangulation data
structure; in the case of the hierarchy, the entire hierarchy is encoded.
- Apollonius_graph_2 and Apollonius_graph_hierarchy_2: added operator>> and
operator<< that read and write from and to a stream; the methods file_input
and file_output are used to implement the two operators.
- modified the test suite to test the above mentioned I/O functionality.
- updated documentation to reflect the newly added I/O functionality.
1 June 2005: Menelaos Karavelas
- added types Arity and result_type in Construct_Apollonius_vertex_2.
- in Construct_Apollonius_*_2: the constructor object for the Apollonius
site or vertex is now taken from the geometric traits.
- fixed bug in visualization of primal Apollonius graph when the dual Voronoi
edge is degenerate (zero length).
29 May 2005: Menelaos Karavelas
- calls to mirror_vertex and mirror_index made through the faces are
now made through the TDS
21 May 2005: Menelaos Karavelas
- added tds() method that returns the triangulation data structure
19 May 2005: Menelaos Karavelas
- added the types Vertex, Face and Triangulation_data_structure in the
Apollonius_graph_2 class; these types should also appear in the doc of
the class
17 May 2005: Menelaos Karavelas
- changed maintainer's email
27 April 2005: Menelaos Karavelas
- fixed misprint sent by Anatoly.Zaretksy <anatoly.zaretsky@gmail.com>
in method: Object_2 dual(const Face_handle& f) of Apollonius_graph_2
7 March 2005: Menelaos Karavelas
- replaced calls to the vertex handle methods degree() and
incident_{edges,faces}() by calls to the corresponding TDS methods that
take the vertex as argument. This was done in compliance with the latest
changes in the design of the Triangulation_2 software.
- modified test suite to comply with the above change
- added access method in Apollonius_graph_2 that returns a const reference
to the TDS.
- added fix for a nasty warning on the PowerPC version of G++ 3.4
4 October 2004: Menelaos Karavelas
- removed "\ccInclude{iostream}" from Apollonius_site_2.tex in the reference
manual; it was causing the manual tools to post a warning
10 September 2004: Menelaos Karavelas
- test.h: fixed typo that was creating an error in Microsoft and
Intel compilers.
7 September 2004: Menelaos Karavelas
- Documentation & code: replaced Agds_2 by Tds_2
6 September 2004: Menelaos Karavelas
- moved {insert,remove}_degree_2 from Agds_2 to Tds_2; kept Agds_2
for backward compatibility
3 September 2004: Menelaos Karavelas
- added chapter author
- added 2004 as a copyright year in files that were modified in 2004
28 August 2004: Menelaos Karavelas
- Parabola_2.h: added hack in order to avoid nasty warning about
static variables that appears on Darwin with G++ 3.4
- moved join_vertices (which was unused) from AGDS2 to TDS2
4 August 2004: Menelaos Karavelas
- added image files in the PNG format for the PDF version of the manual
- fixed problem with hardcoded .eps extension in the manual files
24 June 2004: Menelaos Karavelas
- added fix for SGI compiler for the kernel wrapper
- fixed warning for testsuite when CGAL_NO_ASSERTIONS is defined.
5 June 2004: Menelaos Karavelas
- changed name of line argument in Parabola_2 constructor to avoid
warning of SunPro CC compiler
14 May 2004: Menelaos Karavelas <mkaravel@cse.nd.edu>
- warning of SunPro CC 5.30 for uninitialized variable in
Ag2_infinite_edge_test_C2.h
13 May 2004: Menelaos Karavelas <mkaravel@cse.nd.edu>
- replaced Vertex_handle(NULL) by Vertex_handle()
- replaced comparisons of vertex and face handles against NULL by
comparisons against {Vertex,Face}_handle()
- updated the makefile for the demo (removed the -g flag and old comments)
2 May 2004: Menelaos Karavelas <mkaravel@cse.nd.edu>
- bug fix for VC 7.1 in test suite
- bug fix for sun compiler in Apollonius_graph_2.h
28 April 2004: Menelaos Karavelas <mkaravel@cse.nd.edu>
- fixed bugs in test suite and examples, created by the changes of April 25th
26 April 2004: Menelaos Karavelas <mkaravel@cse.nd.edu>
- CC-5.30_SunOS-5.8 was complaining about the static constants of the
Parabola_2 and Hyperbola_ray_2 classes; these constants are now given
my static methods
25 April 2004: Menelaos Karavelas <mkaravel@cse.nd.edu>
- changes in the traits: moved the various functors from
predicates/Apollonius_graph_predicates_C2.h to separate files named
predicates/Ag2_*.h; the two traits classes have been appropriately modified
- the Apollonius_graph_face_base_2.h file no longer exists; changed the data
structures so that the requirement is now Triangulation_gace_base_2<Gt>;
this reduces the memory requirements
- the version before these (major) changes can be recovered using the tag
before_design_changes_April_2004
- the doc has been appropriately modified to reflect the changes in the
requirements of the face base class
- the doc for the Apollonius_graph_2 class has been modified to define
size_type; also the types that are typedefs from the data structure are now
defined as typedefs instead of nested types
13 April 2004 Menelaos Karavelas
- split the apollonius graph test suite into three separate parts;
this will hopefully decrease compilation time and memory requirements
for the compilation

Qt_widget.h is not used in these files.
1.60 (5 January 2004) [mk]
