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 maxium values of the X, Y and Z extents.

box3d objects have a text representation which looks like BOX3D(1 2 3,5 6 5).
