Libraries SFCGAL applications
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 : Points LineStrings Polygons TriangulatedSurfaces PolyhedralSurfaces GeometryCollections Solids Supported operations include : WKT reading and writing with exact rational number representation for coordinates Intersection operations and predicates Convex hull computation Tessellation Extrusion Area and distance computation Minkovski sums Contour offsets Straight skeleton generations
