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);
Descrizione
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
Questo metodo richiede il backend SFCGAL.
Questa funzione supporta il 3d e non distrugge gli z-index.
