Expand description

Delaunay Triangulation

\param p_cache a memory pointer returned by spatialite_alloc_connection() \param geom pointer to input Geometry object. \param tolerance optional snapping tolerance. \param only_edges if non-zero will return a MULTILINESTRING, otherwise it will return a MULTIPOLYGON containing triangular POLYGONs.

\return the pointer to newly created Geometry object: NULL on failure. \n NULL will be returned if any argument is invalid.

\sa gaiaDelaunatTriangulation, gaiaFreeGeomColl, gaiaVoronojDiagram, gaiaConcaveHull

\note you are responsible to destroy (before or after) any allocated Geometry, this including any Geometry returned by gaiaDelaunayTriangulation_r()\n reentrant and thread-safe.

\remark \b GEOS-TRUNK support required.
