\cgal, the {\em Computational Geometry Algorithms Library}, is written in
|
|
\CC\ and consists of three major parts.
|
|
|
|
The first part is the kernel, which consists of constant-size non-modifiable
|
|
geometric primitive objects and operations on these objects.
|
|
The objects are represented both as stand-alone classes that are
|
|
parameterized by a representation class, which specifies
|
|
the underlying number types used for calculations and as members of the
|
|
kernel classes, which allows for more flexibility and adaptability of the
|
|
kernel.
|
|
|
|
The second part is a collection of basic geometric data structures and
|
|
algorithms, which are parameterized by traits classes that define the
|
|
interface between the data structure or algorithm and the primitives they use.
|
|
In many cases, the kernel classes provided in \cgal\ can be used as traits
|
|
classes for these data structures and algorithms.
|
|
The collection of basic geometric algorithms and data structures
|
|
currently includes polygons, half-edge data structures, polyhedral surfaces,
|
|
topological maps, planar maps, arrangements of curves, triangulations,
|
|
convex hulls, alpha shapes, optimisation algorithms, dynamic
|
|
point sets for geometric queries, and multidimensional search trees.
|
|
|
|
The third part of the library consists of non-geometric support
|
|
facilities, such as support for number types, STL extensions for
|
|
\cgal, handles, circulators, protected access to internal
|
|
representations, geometric object generators, timers, I/O stream
|
|
operators and other stream support including PostScript, colors,
|
|
windows, and visualization tools GeoWin, Geomview and a Qt widget for
|
|
2D \cgal\ objects.
|
|
|
|
Additional documents accompanying the \cgal\ distribution are the
|
|
`Installation Guide' and `The Use of \stl\ and \stl\ Extensions in
|
|
\cgal', which gives a manual style introduction to \stl\ constructs
|
|
such as iterators and containers, as well an extension, called
|
|
circulator, used in many places in \cgal. We also recommend the
|
|
standard text book by Austern~\cite{cgal:a-gps-98} for the \stl\ and
|
|
its notion of \emph{concepts} and \emph{models}.
|
|
|
|
% and `Getting Started with \cgal'
|
|
% The third document gives an introduction in
|
|
% \cgal programming for the novice user.
