This topic describes the ST_MeshFromText function. This function constructs an sfmesh object from the well-known text (WKT) representation of the sfmesh object.
Syntax
sfmesh ST_MeshFromText(text wkt);
sfmesh ST_MeshFromText(text wkt, int4 srid);Parameters
| Parameter | Description |
|---|---|
| wkt | The sfmesh object in WKT representation. |
| srid | The spatial reference identifier. |
Description
This function constructs an sfmesh object from the WKT representation of the sfmesh object.
Examples
SELECT ST_AsEWKT(ST_MeshFromText('{"version" : 1, "root" : 0, "meshgeoms" : ["MESHGEOM(PATCH(TRIANGLESTRIP(0 0,0 10,10 10,10 0)))"], "primitives" : [{"meshgeom" : 0}], "nodes" : [{"primitive" : 0}]}', 4490));
