Introduction

In this tutorial we learn how to install SFCGAL on Fedora 34.

What is `SFCGAL`

SFCGAL is a C++ wrapper library around CGAL with the aim of supporting ISO 19107 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. SFCGAL 1.3.10 4.fc34 x86_64 1.7 M SFCGAL-1.3.10-4.fc34.src.rpm updates C++ wrapper library around CGAL for PostGIS https LGPLv2 SFCGAL is a C++ wrapper library around CGAL with the aim of supporting ISO 19107 SFCGAL provides standard compliant geometry types and operations, that can be accessed from its C or C++ APIs.
