7.10.1. Bounding Box Operators

Name

&&& — Returns TRUE if A’s n-D bounding box intersects B’s n-D bounding box.

Synopsis

+boolean +&&&( geometry A , geometry B );

Description

The &&& operator returns TRUE if the n-D bounding box of geometry A intersects the n-D bounding box of geometry B.

This operand will make use of any indexes that may be available on the geometries.

Availability: 2.0.0

check This method supports Circular Strings and Curves.

check This function supports Polyhedral surfaces.

check This function supports Triangles and Triangulated Irregular Network Surfaces (TIN).

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

Examples: 3D LineStrings

SELECT tbl1.column1, tbl2.column1, tbl1.column2 &&& tbl2.column2 AS overlaps_3d,
                        tbl1.column2 && tbl2.column2 AS overlaps_2d
FROM ( VALUES

    (2, 'LINESTRING Z(1 2 0, 0 5 -1)'::geometry)) AS tbl1,
( VALUES
    (3, 'LINESTRING Z(1 2 1, 4 6 1)'::geometry)) AS tbl2;

 column1 | column1 | overlaps_3d | overlaps_2d
