org.h2gis.api.AbstractFunction
org.h2gis.api.DeterministicScalarFunction
org.h2gis.functions.spatial.create.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.

      public static org.locationtech.jts.geom.GeometryCollection extrudeGeometry(org.locationtech.jts.geom.Geometry geometry, double height) throws SQLException
      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

    • extrudeGeometry

      public static org.locationtech.jts.geom.Geometry extrudeGeometry(org.locationtech.jts.geom.Geometry geometry, double height, int flag) 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
