Hi, in between I checked http://java3d.java.net/ - they still list Java 3D 1.5.2 as their current version. The Java 3D 1.6 link in your post refers to a 1.6 pre-release but I did not find much official stuff. Do you know what the state of Java 3D 1.6 is and if they have an official site to get more information?

Thanks,
Matthias
