Name

ST_RotateZ — Rotates a geometry about the Z axis.

Synopsis

geometry ST_RotateZ(geometry geomA, float rotRadians);

Descrição

Rotates a geometry geomA - rotRadians about the Z axis.

[Note]

This is a synonym for ST_Rotate
[Note]

ST_RotateZ(geomA, rotRadians) is short-hand for SELECT ST_Affine(geomA, cos(rotRadians), -sin(rotRadians), 0, sin(rotRadians), cos(rotRadians), 0, 0, 0, 1, 0, 0, 0).

Melhorias: 2.0.0 suporte para superfícies poliédricas, triângulos e TIN introduzido.

Availability: 1.1.2. Name changed from RotateZ to ST_RotateZ in 1.2.2

[Note]

Anteriores a 1.3.4, essa função falha se usada com geometrias que contêm CURVAS. Isso é consertado em 1.3.4+

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

This method supports Circular Strings and Curves.

This function supports Polyhedral surfaces.

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

Exemplos

--Rotate a line 90 degrees along z-axis
SELECT ST_AsEWKT(ST_RotateZ(ST_GeomFromEWKT('LINESTRING(1 2 3, 1 1 1)'), pi()/2));

 --Rotate a curved circle around z-axis
SELECT ST_AsEWKT(ST_RotateZ(geom, pi()/2))
FROM (SELECT ST_LineToCurve(ST_Buffer(ST_GeomFromText('POINT(234 567)'), 3)) As geom) As foo;
