CircumscribedBall[{p1,p2,…}]
gives a ball with minimal radius that encloses the points p1, p2, ….
Details
- CircumscribedBall is also known as minimal enclosing circle.
- CircumscribedBall gives the Ball of smallest measure (arc length, area, …) that contains all the points pi.

A 2D circumscribed ball from points:
pts = RandomReal[{-1, 1}, {50, 2}];ℛ = CircumscribedBall[pts]The region is the smallest ball that encloses the points:
Region[ℛ, Epilog -> {Black, Point[pts]}]A 3D circumscribed ball from points:

Points (1)
Create a 1D circumscribed ball from a set of points:
pts = RandomReal[{-1, 1}, {50, 1}];ℛ = CircumscribedBall[pts]pts = RandomReal[{-1, 1}, {50, 2}];ℛ = CircumscribedBall[pts]pts = RandomReal[{-1, 1}, {50, 3}];ℛ = CircumscribedBall[pts]Properties & Relations (3)
CircumscribedBall is the smallest Ball that encloses the points:
pts = {{0, 0}, {1, 0}, {2 / 3, 1 / 2}, {0, 1}};Graphics[{ GrayLevel[.5, .5], CircumscribedBall[pts], Red, Point[pts]}]Use InscribedBall to get a largest Ball that lies inside the convex hull of points:
pts = {{0, 0}, {1, 0}, {2 / 3, 1 / 2}, {0, 1}};Graphics[{GrayLevel[.5, .5], ConvexHullRegion[pts], Red, Point[pts], Blue, InscribedBall[pts]}]Use Circumsphere to get the Sphere that circumscribes the points:
pts = {{0, 0}, {1, 0}, {0, 1}};Graphics[{GrayLevel[.5, .5], Circumsphere[pts], Red, Point[pts]}]See Also
