Name
&&&(gidx,gidx) — Returns TRUE if two n-D float precision bounding boxes (GIDX) intersect each other.
Synopsis
boolean &&&( gidx A , gidx B );
Descrizione
The &&& operator returns TRUE if two n-D bounding boxes A and B intersect each other, using float precision. This means that if A (or B) is a (double precision) box3d, it will be internally converted to a float precision 3D bounding box (GIDX)

This operator is intended to be used internally by BRIN indexes, more than by users. |
Availability: 2.3.0 support for Block Range INdexes (BRIN) was introduced. Requires PostgreSQL 9.5+.
Questo metodo supporta le Curve e le Circular String.
Questa funzione supporta le Polyhedral Surface.
Questa funzione supporta i Triangoli e le Triangulated Irregular Network Surfaces (TIN).
Questa funzione supporta il 3d e non distrugge gli z-index.
