Class ST_ConstrainedDelaunay

java.lang.Object
org.h2gis.api.AbstractFunction
org.h2gis.api.DeterministicScalarFunction
org.h2gis.functions.spatial.mesh.ST_ConstrainedDelaunay
All Implemented Interfaces:
org.h2gis.api.Function, org.h2gis.api.ScalarFunction
public class ST_ConstrainedDelaunay extends org.h2gis.api.DeterministicScalarFunction
Returns polygons or lines that represent a Delaunay triangulation constructed from a geometry. Note that the triangulation computes the intersections between lines.
