| Boost.Geometry (aka Generic Geometry Library, GGL), part of collection of the |
| Boost C++ Libraries, defines concepts, primitives and algorithms for solving |
| geometry problems. |
| </p> |
| <p> |
| Boost.Geometry contains a dimension-agnostic, coordinate-system-agnostic and |
| scalable kernel, based on concepts, meta-functions and tag dispatching. On |
| top of that kernel, algorithms are built: area, length, perimeter, centroid, |
| convex hull, intersection (clipping), within (point in polygon), distance, |
| envelope (bounding box), simplify, transform, and much more. The library supports |
| high precision arithmetic numbers, such as <a href="http://www.ttmath.org/" target="_top">ttmath</a>. |
| </p> |
| <p> |
| Boost.Geometry contains instantiable geometry classes, but library users can |
| also use their own. Using registration macros or traits classes their geometries |
| can be adapted to fulfil Boost.Geometry concepts. |
| </p> |
| <p> |
| Boost.Geometry might be used in all domains where geometry plays a role: mapping |
| and GIS, game development, computer graphics and widgets, robotics, astronomy |
| and more. The core is designed to be as generic as possible and support those |
| domains. For now, the development has been mostly GIS-oriented. |
| </p> |
| <p> |
| The library follows existing conventions: |
| </p> |
| <div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "> |
| <li class="listitem"> |
| conventions from boost |
| </li> |
| <li class="listitem"> |
| conventions from the std library |
| </li> |
| <li class="listitem"> |
| conventions and names from one of the <a href="http://www.opengeospatial.org" target="_top">OGC</a> |
| standards on geometry and, more specificly, from the <a href="http://www.opengeospatial.org/standards/sfa" target="_top">OGC |
| Simple Feature Specification</a> |
| </li> |
| </ul></div> |
| <p> |
| The library was first released with Boost 1.47.0 and from that point on it |
| is officially part of the Boost C++ Libraries. |
| </p> |
| <p> |
| Latest stable version of the source code is included in the <a href="http://www.boost.org/users/download/" target="_top">Boost |
| packaged releases</a>. It can also be downloaded from the <a href="http://github.com/boostorg/boost" target="_top">Boost |
| GitHub repository</a> (master branch). |
| </p> |
| <p> |
| The library development upstream is available from the <a href="https://github.com/boostorg/geometry/tree/develop" target="_top">Boost.Geometry |
| (develop branch)</a>. |
| </p> |
| <p> |
| Note that the library <span class="bold"><strong>extensions</strong></span> are not distributed |
| in the official Boost releases, but only available in the <a href="https://github.com/boostorg/geometry/tree/develop" target="_top">Boost.Geometry |
| (develop branch)</a> and that they are subject to change. |
| </p> |
| <p> |
| Boost.Geometry was accepted by Boost at November 28, 2009 (<a href="http://permalink.gmane.org/gmane.comp.lib.boost.announce/246" target="_top">review |
| report</a>). |
| </p> |
| <p> |
| There is a Boost.Geometry <a href="http://lists.boost.org/mailman/listinfo.cgi/geometry" target="_top">mailing |
| list</a>. The mailing list and its messages are also accessible from <a href="http://boost-geometry.203548.n3.nabble.com/" target="_top">Nabble</a> as Boost Geometry. |
| Also on the <a href="http://lists.boost.org/mailman/listinfo.cgi/boost" target="_top">Boost |
| Developers list</a> and on the <a href="http://lists.boost.org/mailman/listinfo.cgi/boost-users" target="_top">Boost |
