com.jme3.bounding.BoundingBox
public class BoundingBox
BoundingBox
defines an axis-aligned cube that defines a
container for a group of vertices of a particular piece of geometry. This box
defines a center and extents from that center along the x, y and z axis.
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
.
