 SFCGAL is a C++ wrapper library around [CGAL](http://www.cgal.org) with the aim of supporting ISO 19107:2013 and [OGC Simple Features Access 1.2](http://www.opengeospatial.org/standards/sfa) for 3D operations.
 
-SFCGAL provides standard compliant geometry types and operations. PostGIS uses the C API, to expose some SFCGAL's functions in spatial databases (cf. [PostGIS manual](https://postgis.net/docs/reference.html#reference_sfcgal)).
