FullConvexHull (h2gis-functions 2.2.0 API)

java.lang.Object
- org.h2gis.functions.spatial.mesh.FullConvexHull

```
public class FullConvexHull
extends Object
```
Computes the convex hull of a Geometry. The convex hull is the smallest convex Geometry that contains all the points in the input Geometry.
Uses the Graham Scan algorithm. For the workaround of Poly2Tri the convex hull must not be simplified

  - getConvexHull
```
public org.locationtech.jts.geom.Geometry getConvexHull()
```
    Returns a Geometry 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.
    
    Returns:
    
    if the convex hull contains 3 or more points, a Polygon; 2 points, a LineString; 1 point, a Point; 0 points, an empty GeometryCollection.
  - toCoordinateArray
```
protected org.locationtech.jts.geom.Coordinate[] toCoordinateArray(Stack stack)
```
    An alternative to Stack.toArray, which is not present in earlier versions of Java.
    
    Parameters:
    
    stack -
