The answer is at http://cg.cs.tu-berlin.de/~ki/engines.html. There are
not only Java 3D engines, but engines for other platforms as well.
Direct link to Java engines page is
http://cg.cs.tu-berlin.de/~ki/3del_26203_hard_java.html.
There are some good engines, but all of them are ENORMOUSLY slow (for
realtime applications at least).
