Format

SDO_CS.MAKE_3D(
     geom2d      IN SDO_GEOMETRY, 
     height      IN NUMBER DEFAULT 0, 
     target_srid IN NUMBER DEFAULT NULL) RETURN SDO_GEOMETRY;

Description

Converts a two-dimensional geometry into a three-dimensional geometry.

Parameters

geom2d

Two-dimensional geometry object.

height

Height value to be used in the third dimension for all vertices in the returned geometry. If this parameter is null or not specified, a height of 0 (zero) is used for all vertices.

target_srid

The SRID of the target coordinate reference system. Must be null or a value in the SRID column of the SDO_COORD_REF_SYS table (described in SDO_COORD_REF_SYS Table).

Usage Notes

For information about using this function to simulate a cross-dimensionality transformation, see Cross-Dimensionality Transformations.

For information about three-dimensional coordinate reference system support, see Three-Dimensional Coordinate Reference System Support.

Examples

The following example converts the cola_a two-dimensional geometry to a three-dimensional geometry. (This example uses the definitions from the example in Example of Coordinate System Transformation.).

SELECT SDO_CS.MAKE_3D(c.shape, 10, 8307) FROM cola_markets_cs c
  WHERE c.name = 'cola_a';
