It is not important. While you won't be able to build full 
implementation of java3d without it, I still have to see even one 
program to use it. Idea behind compression was to have specialized GPU 
capable to understanding it directly, to conserve bus bandwidth. Sun has 
built one or two such cards and that's it - using compressed geometry 
without hardware acceleration is just going to be a slower than normal one.

As for the 'free' implementation of java3d, xith3d is probably a good 
place to start. It has most of java3d features implemented already, at 
least as far as desktop targets are concerned. For the vecmath, Kenji's 
version can be used. java3d-util package is available under free license 
from sun.

There is for sure certain amount of work to be done to allow xith3d to 
be used in place of java3d for LG - but it should be possible to manage.
