Java 3D is thread-safe only in that it is permissible to make scene
graph modifications, including branch graph insertion and removal, from
any thread while Java 3D is running. It is also permissible to make
modifications to two different objects from different threads. For
example, you can have an interpolator behavior operating on one
transform group in your scene graph, while an AWT event behavior
modifies another transform group in parallel (all while Java 3D is
rendering the scene). It is not permissible to modify the same Java 3D
object from two different threads without externally synchronizing the
access.

>Hi all, I am a new user of Java3D, and I was wondering if Java3D was

>because we are using several behaviors and such.) We enabled the write
