Dear Developers, The formal review of the Boost.Polygon library by Lucanus Simonson starts today, August 24, 2009 and will finish September 2, 2009. I really hope to see your vote and your participation in the discussions on the Boost mailing lists! --------------------------------------------------- About the library: The boost polygon library provides algorithms focused on manipulating planar polygon geometry data. Specific algorithms provided are the polygon set operations (intersection, union, difference, disjoint-union) and related algorithms such as polygon connectivity graph extraction, offsetting and map-overlay. These so-called Boolean algorithms are of significant interest in GIS (Geospatial Information Systems), VLSI CAD as well al other fields of CAD, and many more application areas, and providing them is the primary focus of this library. The polygon library is not intended to cover all of computational geometry in its scope, and provides a set of capabilities for working with coordinates, points, intervals and rectangles that are needed to support implementing and interacting with polygon data structures and algorithms. Specifically, 3d and non-Cartesian/non-planar geometry is outside of the scope of the polygon library The design philosophy behind the polygon library was to create an API for invoking the library algorithms it provides on user geometry data types that is maximally intuitive, minimally error-prone and easy to integrate into pre-existing applications. C++-concepts based template meta-programming combined with generic operator overloading meets these design goals without sacrificing the runtime or memory efficiency of the underlying algorithms. This API makes the following code snippet that operates on non-library geometry types possible: void foo(list<CPolygon>& result, const list<CPolygon>& a, const list<CPolygon>& b, int deflateValue) { CBoundingBox domainExtent; using namespace boost::polygon::operators; boost::polygon::extents(domainExtent, a); result += (b & domainExtent) ^ (a - deflateValue); } The source is available at http://svn.boost.org/svn/boost/sandbox/gtl/boost/polygon/ And the documentation is at http://svn.boost.org/svn/boost/sandbox/gtl/doc/index.htm --------------------------------------------------- Please always state in your review, whether you think the library should be accepted as a Boost library! Additionally please consider giving feedback on the following general topics: - What is your evaluation of the design? - What is your evaluation of the implementation? - What is your evaluation of the documentation? - What is your evaluation of the potential usefulness of the library? - Did you try to use the library? With what compiler? Did you have any problems? - How much effort did you put into your evaluation? A glance? A quick reading? In-depth study? - Are you knowledgeable about the problem domain?
