|
Mariette's suggestions/comments
|
|
- modified testing accordingly
|
|
- added insertion methods and constructors in the DelaunayGraph_2 concept;
|
|
The Triangulation_hierarchy_2 class is no longer a model of the concept: it
|
|
lacks a constructor that takes an iterator range.
|
|
- added generator iterator in testsuites; generator iterator may need some
|
|
more work. Open question: should sites be renamed to generators?
|
|
|
|
4 October 2005: Menelaos Karavelas
|
|
- renamed namespace Voronoi_diagram_2_namespace to VoronoiDiagram_2

|
|
diagram features
|
|
|
|
3 August 2005: Menelaos Karavelas
|
|
- the demo now shows the conflict region for a site. The code is kind
|
|
of ugly and should be modified; the color of the site should be
|
|
different from the color of the conflict region. the conflict region
|
|
is not yet done for the Apollonius diagram
|
|
|
|
30 July 2005: Menelaos Karavelas
|
|
- removed duplicate typedef in Virtual_Voronoi_diagram_base_2 class;
|
|
g++ version 4.x.x was complaining.
|
|
|

|
adaptor, that are used for drawing to Qt_widget
|
|
- code:
|
|
* removed the Voronoi_edge_2 and Voronoi_vertex_2 classes from the

|
* added first attempt for implementation of identity Voronoi traits
|
|
- testing: removed testing for Voronoi_edge_2 and Voronoi_vertex_2 concepts;

|
|
a method called simply dual().
|
|
- removed references to holes in both doc and code
|
|

|
|
|
|

|
|
- in VoronoiEdge_2: renamed north,south,west,east to up,down,left,right
|

respectively.
|
|
|
|
25 June 2005: Menelaos Karavelas
|
|
Manual:
|
|
- added user manual
|
|
- added bounded faces iterator, unbounded/bounded halfedges iterator
|
|
in VDA interface
|
|
- added more comments in examples
|
|
- modified VoronoiDiagram{Halfedge,Vertex,Face}_2 concepts; the concepts are
|
|
no longer refinements of the planar map or topological map corresponding
|
|
concepts, but rather stand alone; as a result I had to add all needed types
|
|
and methods.
|
|
- modified the VoronoiEdge_2 concept: the Point_2 is no longer required
|
|
- modified the VoronoiVertex_2 concept: the Point_2 is required to be the
|
|
Point_2 type of the geometric traits of the dual graph
|
|
Test:
|
|
- added singleton data set for regular triangulation
|
|
- collected various helper functions in single file
|
|
- added very thourough testing for the various concepts and the adaptor itself;
|
|
much of the code in print_report has been moved to the test_vda function.
|
|
- added testing of singleton data sets
|
|
- added copyright headers
|
|
- the Delaunay_graph_concept class now uses the dummy iterator in
|
|
include/CGAL/Voronoi_diagram_adaptor_2/Dummy_iterator.h
|
|
- added missing access methods in Delaunay_graph_concept
|
|
Examples:
|
|
- stylistic changes so that they look nice in the manual
|
|
Code:
|
|
- fixed bug in face degeneracy tester of the segment Voronoi diagram traits:
|
|
the tester was not handling correctly the case where we have a single
|
|
generator (i.e., when the dimension of the Delaunay graph was 0).
|
|
- added in Dummy_iterator: decrement operators,
|
|
const_pointer/const_reference types and corresponding operators,
|
|
operator<, access to default value
|
|
- circulators are now convertible to handles
|
|
- The base iterator in the halfedge iterator adaptor is no longer hardcoded;
|
|
also the edge iterator adaptor takes a true/false tag that helps adapting
|
|
how the value of the iterator is computed; all these are needed for fixes
|
|
in the various edge iterators and for the introduction of the
|
|
unbounded/bounded halfedge iterators
|
|
- added the class Accessor which is a friend of the Voronoi_diagram_adaptor_2
|
|
class; this class is meant to be used as a way to access private types or
|
|
data from the Voronoi_diagram_adaptor class.
|
|
- added testers for unbounded/bounded halfedges and bounded faces
|
|
- added code for bounded faces iterator, unbounded/bounded halfedges
|
|
iterator
|
|
- added support for Voronoi diagrams with a single generator
|
|
- fixed minor bugs in the adaptor class
|
|
|
|
21 June 2005: Menelaos Karavelas
|
|
- manual: added intro to the ref manual
|
|
- manual: added models to various concepts
|
|
- manual: changed names of some template paremeters
|
|
|
|
18 June 2005: Menelaos Karavelas
|
|
- fixed the point_location example w.r.t. the changes made on June 16;
|
|
the Locate_type classes is now used in the example as well.
|
|
- changed the spec for the face denegeracy tester: we do not require
|
|
any more operators that take iterators or circulators as arguments; since
|
|
iterators and circulators are convertible to handles, these operators are
|
|
not really required. In addition this should fix the bug with the VC 7.1
|
|
compiler.
|
|
- changed the code to reflect the change in the spec discussed above.
|
|
- introduced a Default_face_degeneracy_tester that always returns false; now
|
|
all Voronoi traits except that of the SVD use this default tester instead
|
|
of defining their own
|
|
- modified the cached and ref counted Voronoi traits to define the point
|
|
locator as well
|
|
- added concepts for locate types in the doc; added usage of locate types
|
|
in the various classes/concepts
|
|
- modified copyright headers in doc
|
|
- added the two examples in the doc
|
|
|
|
16 June 2005: Menelaos Karavelas
|
|
- added some more data sets for testing with regular triangulation's point
|
|
location
|
|
- added Locate_type classes
|
|
- the locate methods now return proper Locate_type classes instead of Object
|
|
|
|
12 June 2005: Menelaos Karavelas
|
|
- added point location functionality for Delaunay triangulations, Apollonius
|
|
graphs and segment Voronoi diagrams (in their traits).
|
|
- added point location functionality (and testing) in the Voronoi diagram
|
|
adaptor.
|
|
- added one more example that does point location.
|
|
- added support (and testing) for 1-dimensional Delaunay graphs.
|
|
- added some more test data sets for testing point location and support
|
|
for 1-dimensional Delaunay graphs
|
|
|
|
11 June 2005: Menelaos Karavelas
|
|
- added copyright headers in some files that did not have one
|
|
- changed institution in copyright headers
|
|
- added Connected_components.h which contains a generic algorithm for
|
|
computing the number of connected components of the Voronoi skeleton
|
|
|
|
4 June 2005: Menelaos Karavelas
|
|
- in Dummy_iterator and Circulator_from_halfedge_adaptor: operator*() and
|
|
operator->() that returned a const reference and const pointer have been
|
|
removed (in order to avoid warnings by icc/icpc/icl and cl compilers);
|
|
moreover, these operators are not really used.
|
|
- in *_Voronoi_traits_2 classes and in Voronoi_traits_concept class:
|
|
icc/icpc/icl and cl compilers have a problem with the declaration of
|
|
Voronoi_edge_base_2 as a friend when this declaration is done through the
|
|
parent class; created a CGAL config file and added the appropriate
|
|
#ifndef - #endif block that checks for this problem.
|
|
- fixed warning for unused variables when NDEBUG is defined
|
|
- fixed unused variable warning in Halfedge.h and vda_print_report.h
|
|
|
|
27 May 2005: Menelaos Karavelas
|
|
- changes in the doc:
|
|
* fixed some open issues in the various models of the Voronoi traits concept.
|
|
* added concepts for halfedges, vertices, faces of the Voronoi diagram.
|
|
* added concepts for Voronoi edges and vertices, seen as geometric objects.
|
|
* extended the VoronoiTraits_2 concept to incorporate geometric objects,
|
|
such as Voronoi vertices and edges.
|
|
* fixed Voronoi_diagram_adaptor_2 doc to make references to appropriate
|
|
concepts and also fixed return types of various iterators/circuclator (in
|
|
compliance with the arrangements'API).
|
|
- changes in the code:
|
|
* changed return type for Halfedge_around_vertex_circulator and
|
|
Ccb_halfedge_circulator to be Halfedge instead of Halfedge_handle.
|
|
* changed return type of Holes_iterator from Halfedge_handle to
|
|
Ccb_halfedge_circulator.
|
|
* added methods point() in Vertex and curve() in Halfedge; added the
|
|
corresponding support in the Voronoi traits classes and created the
|
|
appropriate base classes for representing Voronoi vertices and edges (seen
|
|
now as geometric objects).
|
|
* Voronoi_diagram_adaptor_2 class: removed predicate methods to simplify the
|
|
interface; these methods were simply shortcuts to other calls, accessible
|
|
publicly to the user.
|
|
* the Voronoi_diagram_adaptor_2 class now uses the cached testers by default;
|
|
however the interface is not very very clean since the edge_tester() and
|
|
face_tester() methods are still public.
|
|
* removed definition of Edge_hash_function in the
|
|
Cached_edge_degeneracy_tester since it was identical to that in
|
|
CGAL/edge_list.h; the definition in CGAL/edge_list.h is now used.
|
|
- changes in testsuite:
|
|
* updated Delaunay_graph_concept and Voronoi_traits_concept classes in order
|
|
to comply with the recent changes.
|
|
* the vda_*.C testsuites are now using the normal traits classes and not
|
|
the cached traits classes.
|
|
* updated the concept checking method in include/vda_test_concept.h to test
|
|
for recently added types
|
|
* updated vda_print_report.h w.r.t. changes referring to eliminated predicate
|
|
methods in Voronoi_diagram_adaptor_2; also added tests for the geometric
|
|
objects returned by Vertex and Halfedge (point() and curve() respectively.
|
|
- other changes:
|
|
* added example that computes the number of connected components of the
|
|
Voronoi skeleton.
|
|
|
|
24 May 2005: Menelaos Karavelas
|
|
- changed the return type of the circulators to be Halfedge instead of
|
|
Halfedge_handle.
|
|
- changed the return type of Holes_iterator from Halfedge_handle to
|
|
Ccb_halfedge_circulator.
|
|
|
|
22 May 2005: Menelaos Karavelas
|
|
- re-wrote the face degeneracy testers so that they do not need the edge
|
|
degeneracy tester as an argument. This simplifies both the code and the
|
|
concepts.
|
|
- fixed wrong names of types in the Voronoi_diagram_adaptor_2 class and
|
|
dependent classes
|
|
|
|
21 May 2005: Menelaos Karavelas
|
|
- renamed Degeneracy_testers.h Validity_testers.h
