You can't really run Java3D in an "emulation" mode. That would really
mean that Java3D would have to include software-only versions of all the
3D calls it makes. You CAN put DirectX in emulation mode, and on Linux
you can use Mesa instead of OpenGL for emulation, but you can't run
Java3D on Macs. Period. It has not been done for Macs because Macs do
not have Java 2 support (yet). When they do (Mac OS X), Java3D will
have to been written to use the OpenGL on Macs.
In conclusion, Java3D does not support lightweight functionality at all,
and thus cannot "run on any system".
