com.ardor3d.bounding.BoundingSphere
BoundingSphere defines a sphere that defines a container for a group of vertices of a particular piece of geometry. This sphere defines a radius and a center.

A typical usage is to allow the class define the center and radius by calling either containAABB or averagePoints. A call to computeFramePoint in turn calls containAABB.
