For more information on lights, shadows, why Java 3D does not do them,
how you can do them; check out Chapter 6 of the Java 3D API Tutorial.
(see the bottom of this message).
If the application is to be the sun and a house, creating shadows is
not the way to go. You should consider Light Scoping (not bounds)
to control the influence of lights. This is also explained in
Chapter 6.
Bounds would be difficult, if not impossible to use because it
limits a light's influence based on geometric position. The
interior of the house (not lit) is likely to be positioned
close to the house exterior (lit) and therefore finding a
bounds that works is very hard.
Scoping allows you to limit the influence of lights based on
the scene graph.
good luck,
Dennis
