Syntax
meshgeom ST_MeshGeomFromWKB(bytea wkb);
meshgeom ST_MeshGeomFromWKB(bytea wkb, int4 srid);Parameters
| Parameter | Description |
|---|---|
wkb | The meshgeom object in WKB representation. |
srid | The spatial reference identifier (SRID). |
Example
SELECT ST_AsEWKT(ST_MeshGeomFromWKB(ST_AsWKB('MESHGEOM(PATCH(INDEXSURFACE(VERTEX(0 0 2,0 10 3,10 10 1,10 0 1), INDEX((0,1,2),(1,2,3)))))'::meshgeom)));Output:
st_asewkt
