List of convexHull() Examples

Examples of convexHull()

com.vividsolutions.jts.geom.Geometry.convexHull()
Computes the smallest convex Polygon that contains all the points in the Geometry. This obviously applies only to Geometry s which contain 3 or more points; the results for degenerate cases are specified as follows:

Number of Points in argument Geometry Geometry class of result

0 empty GeometryCollection

1 Point

2 LineString

3 or more Polygon

@return the minimum-area convex polygon containing this Geometry's points
com.vividsolutions.jts.geom.GeometryCollection.convexHull()
com.vividsolutions.jts.geom.LineString.convexHull()
com.vividsolutions.jts.geom.MultiPoint.convexHull()

Number of `Point`s in argument `Geometry`	`Geometry` class of result
0	empty `GeometryCollection`
1	`Point`
2	`LineString`
3 or more	`Polygon`
