ITopologicalOperator.ConvexHull Method

Constructs the convex hull of this geometry.

[Visual Basic .NET]
Public Function ConvexHull ( _
) As IGeometry
public IGeometry ConvexHull (
HRESULT ConvexHull(

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.


The ConvexHull of a geometry is the minimal bounding polygon such that all outer angles are convex. The ConvexHull of a point is the point itself.


ITopologicalOperator methods must be applied on high-level geometries only. High-Level geometries are point, multipoint, polyline and polygon. To use this method with low-level geometries such as segments (Line, Circular Arc, Elliptic Arc, B�zier Curve), paths or rings, they must be wrapped into high-level geometries types.

This method does not support GeometryBags. 

ConvexHull method does not deal with Z attribute now.
