ST_DelaunayTriangles (Python)

Computes the Delaunay Triangles of the vertices of the input geometry. SQL reference: ST_DelaunayTriangles

Signature

from sedona.spark.sql.st_functions import ST_DelaunayTriangles

ST_DelaunayTriangles(
    geometry: ColumnOrName,
    tolerance: Optional[Union[ColumnOrName, float]] = None,
    flag: Optional[Union[ColumnOrName, int]] = None,
) -> Column

Parameters

ColumnOrName

required

Input geometry

Optional[Union[ColumnOrName, float]]

default:"None"

Distance within which input vertices are snapped together before triangulating. Default is 0.

Optional[Union[ColumnOrName, int]]

default:"None"

Selects the output type: 0 (default) for a GeometryCollection of triangular Polygons, or 1 for a MultiLineString of the triangulation’s edges.

Returns

ColumnOrName

Delaunay triangles of the input geometry
