SFCGAL C++ wrapper library around CGAL
This library support ISO 19107:2013, OGC Simple Features Access 1.2 for 3D operations.
It 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. Among supported geometry types are :
Supported operations include :
WKT reading and writing with exact rational number representation for coordinates
Intersection operations and predicates
Convex hull computation
Area and distance computation
Straight skeleton generations
