ol-ext: Convex hull
The
ol.coordinate.convexHull()
function calculate a
convex hull
or convex envelope, ie. the smallest polygon that contains all points of a set.
It uses the
Andrew's Monotone Chain Algorithm
to complete the hull.
It can be used to display a polygon
around the points of a cluster
.
