Class ST_Extrude

  • All Implemented Interfaces:
    org.h2gis.api.Function, org.h2gis.api.ScalarFunction

    public class ST_Extrude
    extends org.h2gis.api.DeterministicScalarFunction
    ST_Extrude takes a LINESTRING or POLYGON as input and extends it to a 3D representation, returning a geometry collection containing floor, ceiling and wall geometries. In the case of a LINESTRING, the floor and ceiling are LINESTRINGs; for a POLYGON, they are POLYGONs.

        Extrudes a POLYGON or a LINESTRING into a GEOMETRYCOLLECTION containing the floor (input geometry), walls and ceiling. Note : the NaN z value of the input geometry are replaced by a zero.
        Parameters:
        geometry - Input geometry
        height - Desired height
        Returns:
        Collection (floor, walls, ceiling)
        Throws:
        SQLException

        Extrudes a POLYGON or a LINESTRING into a GEOMETRYCOLLECTION containing the floor (input geometry), walls and ceiling. A flag of 1 extracts walls and a flag of 2 extracts the roof.
        Parameters:
        geometry - Input geometry
        height - Desired height
        flag - 1 (walls), 2 (roof)
        Returns:
        Walls or roof
        Throws:
        SQLException
