In a case like this, where you are over-riding a method
defined in ShadowTypeJ3D (the base class of the Shadow*TypeJ3D
hierarchy), you should implement it in all your Shadow*Type
classes. If you can put the real logic in a static method
in a single class, invoked from small methods in all the
others classes, that will save redundant coding.

Cheers,
Bill
