## Name

&&& — Gibt `TRUE` zurück, wenn A's n-D bounding box B's n-D bounding box schneidet.

## Synopsis

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

## Beschreibung

Der `&&&` Operator gibt `TRUE` zurück, wenn die n-D bounding box der Geometrie A die n-D bounding box der Geometrie B schneidet.

 Dieser Operand benützt jeden Index, der für die Geometrie zur Verfügung stellt.

## Beispiele: 3D LineStrings

```SELECT tbl1.column1, tbl2.column1, tbl1.column2 &&& tbl2.column2 AS overlaps_3d,
tbl1.column2 && tbl2.column2 AS overlaps_2d
FROM ( VALUES
(1, 'LINESTRING Z(0 0 1, 3 3 2)'::geometry),
(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
---------+---------+-------------+-------------
1 |       3 | t           | t
2 |       3 | f           | t
```

## Beispele: 3M LineStrings
