ST_3DIntersects — Tests if two geometries spatially intersect in 3D - only for points, linestrings, polygons, polyhedral surface (area).
boolean ST_3DIntersects(
geometry
geomA
,
geometry
geomB
)
;
Overlaps, Touches, Within all imply spatial intersection. If any of the aforementioned returns true, then the geometries also spatially intersect. Disjoint implies false for spatial intersection.
This function automatically includes a bounding box comparison that makes use of any spatial indexes that are available on the geometries. |
Changed: 3.0.0 SFCGAL backend removed, GEOS backend supports TINs.
Availability: 2.0.0
This function supports 3d and will not drop the z-index.
This function supports Polyhedral surfaces.
This function supports Triangles and Triangulated Irregular Network Surfaces (TIN).
This method implements the SQL/MM specification. SQL-MM IEC 13249-3: 5.1
