Name
CG_Scale3D — Scales a geometry by separate factors along X, Y, and Z axes.
Synopsis
geometry CG_Scale3D(geometry geom, float8 factorX, float8 factorY, float8 factorZ);
Description
Scales the input geometry geom by different factors along the X, Y, and Z axes. The scaling is performed relative to the origin point (0,0,0).
Availability: 3.6.0 - requires SFCGAL >= 2.0.0
Cette méthode nécessite le backend SFCGAL.
Cette fonction prend en charge la 3D et ne supprime pas l'indice z.
Exemples
SELECT ST_AsText(CG_Scale3D('POINT(1 1 1)', 2, 3, 4));
-- Result: POINT(2 3 4)
