CG_3DRotate — Rotates a geometry in 3D space around an axis vector.
geometry CG_3DRotate(
geometry geom, float8 angle, float8 ax, float8 ay, float8 az)
;
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
Cette méthode nécessite le backend SFCGAL.
Cette fonction prend en charge la 3D et ne supprime pas l'indice z.
