Boost.Geometry is a template C++ library, included in Boost. It contains geometry classes (such as point, linestring, polygon) and functions (such as distance, intersection, union). Boost.Geometry is Concept based and users can use their own models of e.g. point.
Boost.Geometry (aka Generic Geometry Library, GGL), part of collection of the Boost C++ Libraries, defines concepts, primitives and algorithms for solving geometry problems.
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 ttmath.
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 fulfill Boost.Geometry concepts.
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. Currently, the development has been mostly GIS-oriented.
