ST_Tesselate — Perform surface Tessellation of a polygon or polyhedralsurface and returns as a TIN or collection of TINS
geometry ST_Tesselate(
geometry geom)
;
ST_Tesselate is deprecated as of 3.5.0. Use CG_Tesselate instead. |
Takes as input a surface such a MULTI(POLYGON) or POLYHEDRALSURFACE and returns a TIN representation via the process of tessellation using triangles.
ST_TriangulatePolygon does similar to this function except that it returns a geometry collection of polygons instead of a TIN and also only works with 2D geometries. |
Disponibilità: 2.1.0
