Package org.h2gis.functions.spatial.mesh

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.
