C++ wrapper library around CGAL for PostGIS
SFCGAL is a C++ wrapper library around CGAL with the aim of supporting ISO 19107:2013 and OGC Simple Features Access 1.2 for 3D operations. SFCGAL provides standard compliant geometry types and operations, that can be accessed from its C or C++ APIs. PostGIS uses the C API, to expose some SFCGAL's functions in spatial databases (cf. PostGIS manual). Geometry coordinates have an exact rational number representation and can be either 2D or 3D.
