Westley,
Actually most users should only need to install Java 1.3 and Java 3D.
OpenGL and DirectX support should be pre-installed on MOST PCs (with the
notable exception of don't try to use DirectX on WinNT). Only very old
Win95 machines might not have OpenGL (and those machines probably can't
run a complex 3D scene anyway). Sun has indicated they'll provide a
signed jar in June so this process could be made *nearly* automatic.
You won't find a "Java 3D light" (not from Sun anyway), but some other
people have written 3D libraries in pure Java (naturally you are
restricting yourself to very simple scenes due to performance issues).
