that represents the convex hull of the input
geometry.
The returned geometry contains the minimal number of points needed to
represent the convex hull. In particular, no more than two consecutive
points will be collinear.Polygon
;
2 points, a LineString
;
1 point, a Point
;
0 points, an empty GeometryCollection
