CG_Scale3DAroundCenter — Scales a geometry in 3D space around a specified center point.
geometry CG_Scale3DAroundCenter(
geometry geom, float8 factorX, float8 factorY, float8 factorZ, float8 centerX, float8 centerY, float8 centerZ)
;
Scales the input geometry geom
by different factors along the X, Y, and Z axes, relative to a specified center point (centerX
, centerY
, centerZ
).
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.
