CG_Scale3D — Scales a geometry by separate factors along X, Y, and Z axes.
geometry CG_Scale3D(
geometry geom, float8 factorX, float8 factorY, float8 factorZ)
;
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
Diese Methode benötigt ein SFCGAL-Backend.
Diese Funktion unterstützt 3d und lässt den Z-Index nicht fallen.
