Name

CG_3DScale — Scales a geometry by separate factors along X, Y, and Z axes.

Synopsis

geometry CG_3DScale(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_3DScale('POINT(1 1 1)', 2, 3, 4));
-- Result: POINT(2 3 4)
