Ingo,
Thanks for the test program. I've filed a bug report for further
investigation.
Bug Id: 4619121 - OrientedShape3D under a combination of SharedGroup and
Switch nodes fail to work.
John, are you encountering the similar bug as Ingo ? If not, please do
send us a test program. We need your help to have a stable j3d1.3 release.
thanks,
Chien Yang
Java 3D Team.
