Class BoundingBox

BoundingBox allows to transform objects (rotate and scale) and draws a cube around the object to visualize the possibility of user triggered transform manipulation. BoundingBox provides scale and rotation handles that can be used for far and near interaction manipulation of the object. It further provides a proximity effect for scale and rotation handles that alters scaling and material.
