Ritter's bounding sphere
In mathematics, given a non-empty set of objects of finite extension in $${\displaystyle d}$$-dimensional space, for example a set of points, a bounding sphere, enclosing sphere or enclosing ball for that set is an $${\displaystyle d}$$-dimensional solid sphere containing all of these objects. Used … See more Clustering Such spheres are useful in clustering, where groups of similar data points are classified together. In statistical analysis the scattering of data points within … See more There are exact and approximate algorithms for the solving bounding sphere problem. Linear programming Nimrod Megiddo studied the 1-center problem extensively and published on it at least five times in … See more • Bounding volume • Circumscribed sphere, circumscribed circle See more • Smallest Enclosing Circle Problem – describes several algorithms for enclosing a point set, including Megiddo's linear-time algorithm See more WebMay 23, 2011 · Basically, if I have a cube and calculate the radius with this approach, the sphere will leave the cube corners outside. Second approach: Divide each axis by 2 and that will give me the radius on each axis. Then I do this to take out the radius for the bounding sphere: r = SQRT (x*x + y*y + z*z) But this gives me a pretty large radius.
