Name

ST_RotateY — Rotates a geometry about the Y axis.

Synopsis

geometry ST_RotateY(geometry geomA, float rotRadians);

Descripción

Rotates a geometry geomA - rotRadians about the y axis.

[Note]

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

Availability: 1.1.2. Name changed from RotateY to ST_RotateY in 1.2.2

Mejorado: 2.0.0 se introdujo soporte para superficies poliédricas, Triangulos y TIN.

This function supports Polyhedral surfaces.

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

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

Ejemplos

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