Name

CG_3DScaleAroundCenter — Scales a geometry in 3D space around a specified center point.

Synopsis

geometry CG_3DScaleAroundCenter ( geometry geom , float8 factorX , float8 factorY , float8 factorZ , float8 centerX , float8 centerY , float8 centerZ ) ;

Description

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

This method needs SFCGAL backend.

This function supports 3d and will not drop the z-index.

Examples 

SELECT ST_AsText(CG_3DScaleAroundCenter('POINT(2 2 2)', 0.5, 0.5, 0.5, 1, 1, 1));
-- Result: POINT(1.5 1.5 1.5)
