8.15. Affine Transformations

Name

ST_RotateX — Rotates a geometry about the X axis.

Synopsis

geometry +`*`+ST_RotateX*(`geometry `geomA, float rotRadians`)`;

Description

Rotates a geometry geomA - rotRadians about the X axis.

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

Enhanced: 2.0.0 support for Polyhedral surfaces, Triangles and TIN was introduced.

Availability: 1.1.2. Name changed from RotateX to ST_RotateX in 1.2.2

check This function supports Polyhedral surfaces.

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

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

Examples

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