box3d — The type representing a 3-dimensional bounding box.
box3d is a PostGIS spatial data type used to represent
the three-dimensional bounding box enclosing a geometry or collection of geometries.
For example, the ST_3DExtent aggregate function returns a box3d object.
The representation contains the values xmin, ymin, zmin, xmax, ymax, zmax.
These are the minimum and maximum values of the X, Y and Z extents.
box3d objects have a text representation which looks like BOX3D(1 2 3,5 6 5).
This table lists the automatic and explicit casts allowed for this data type:
| Cast To | Behavior |
