This topic describes the ST_AsGeometry function. This function constructs a geometry from an object of any type.
Syntax
geometry ST_AsGeometry(meshgeom geom);
geometry ST_AsGeometry(sfmesh sfmeshObject);Parameters
| Parameter | Description |
|---|---|
| geom | The meshgeom object. |
| sfmeshObject | The sfmesh object. |
Description
This function constructs a geometry from an object of any type. The type of the geometry is a collection type, which can be GeomCollection or MultiPolygon.
Examples
select ST_AsWKT(ST_AsGeometry(ST_MeshFromText('{"version" : 1, "root" : 0, "meshgeoms" : ["MESHGEOM(PATCH(INDEXSURFACE Z (VERTEX(0 0 2,0 10 3,10 10 1,10 0 1),INDEX((0,1,2),(1,2,3)))))"], "primitives" : [{"meshgeom" : 0}], "nodes" : [{"primitive" : 0}]}')));
