- Remarks:
- In section 12.4.2 [JTS1.4 ] states: "The convex hull of a Geometry is the smallest convex Polygon that contains all the points in the Geometry. If the convex hull contains fewer than 3 points, a lower dimension Geometry is returned, specified as follows:
Points in Convex Hull | Geometry of Result |
0 | empty GeometryCollection |
1 | Point |
2 | LineString |
3 or more | Polygon |
JTS will return a Geometry with the minimal number of points needed to represent the convex hull. In particular, no more than two consecutive points will be collinear."
- Returns:
- An MgGeometry that represents the convex hull of the geometric entity.
