Name
CG_Rotate3D — Rotates a geometry in 3D space around an axis vector.
Synopsis
geometry CG_Rotate3D(geometry geom, float8 angle, float8 ax, float8 ay, float8 az);
描述
Rotates the input geometry geom by angle radians around an axis defined by the vector (ax, ay, az) passing through the origin (0,0,0).
Availability: 3.6.0 - requires SFCGAL >= 2.0.0
该方法需要SFCGAL后端。
该函数支持 3d 并且不会丢失 z-index。
示例
SELECT ST_AsText(CG_Rotate3D('POINT(1 0 0)', pi()/2, 0, 0, 1));
-- Result: POINT(0 1 0)
