pts = RandomReal[{-1, 1}, {50, 2}];ℛ = CircumscribedBall[pts]Region[ℛ, Epilog -> {Black, Point[pts]}]pts = RandomReal[{-1, 1}, {50, 3}];ℛ = CircumscribedBall[pts]Show[{Region[Style[Point[pts], Black]], Region[Style[ℛ, Opacity[.5]]]}]范围 (1)
点 (1)
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]属性和关系 (3)
CircumscribedBall 是包围所有点的最小的 Ball：
pts = {{0, 0}, {1, 0}, {2 / 3, 1 / 2}, {0, 1}};Graphics[{ GrayLevel[.5, .5], CircumscribedBall[pts], Red, Point[pts]}]用 InscribedBall 获取位于点的凸包内的最大的 Ball：
pts = {{0, 0}, {1, 0}, {2 / 3, 1 / 2}, {0, 1}};Graphics[{GrayLevel[.5, .5], ConvexHullRegion[pts], Red, Point[pts], Blue, InscribedBall[pts]}]用 Circumsphere 获取包围这些点的 Sphere：
pts = {{0, 0}, {1, 0}, {0, 1}};Graphics[{GrayLevel[.5, .5], Circumsphere[pts], Red, Point[pts]}]
