Name
CG_GenerateFlatRoof — Generate a flat (box) roof from a footprint polygon.
Synopsis
geometry CG_GenerateFlatRoof(geometry geom, float8 height);
Beschreibung
Generate a flat (box-shaped) roof as a 3D PolyhedralSurface Z from a 2D footprint polygon. The roof height above the ground plane is given by height (default 3.0).
Availability: 3.7.0 - requires SFCGAL >= 2.3.0.
Diese Methode benötigt ein SFCGAL-Backend.
Diese Funktion unterstützt polyedrische Flächen.
Beispiele
SELECT ST_AsText(
CG_GenerateFlatRoof(
