ConvexHull[{{x1,y1},{x2,y2},…}]
yields the planar convex hull of the points {{x1,y1},…}, represented as a list of point indices arranged in counterclockwise order.


ConvexHull
ConvexHull[{{x1,y1},{x2,y2},…}]
yields the planar convex hull of the points {{x1,y1},…}, represented as a list of point indices arranged in counterclockwise order.
Details and Options
- ConvexHull functionality is now available in the built-in Wolfram Language function ConvexHullMesh.
- To use ConvexHull, you first need to load the Computational Geometry Package using Needs["ComputationalGeometry`"].
- The following option can be given:
-
AllPoints True whether to include all distinct points - With the setting AllPoints->False, only the minimum set of points needed to define the hull is returned.
