That is correct. You have to be part of a live scene to call that method.
That is because there is no "root" by which to calculate the ultimate
destination of the points until it exists within the live scene.

Subject: Re: [JAVA3D] obj coordinates
Hi,
Thanks for your help, but I just can't find the
getLocalToVWorldTransform() class.
I tried to use the getLocalToVworld() class instead,
but it does not seems to work.
Here is my code:
...
objs= scene.getNamedObjects();
Set keys = objs.keySet();
Iterator ite = keys.iterator();
while (ite.hasNext()){
Shape3D node = (Shape3D) objs.get(ite.next());
if (node != null) {
node.setAppearance(appearance1);
}
Transform3D t3d3 = new Transform3D();
try{
node.getLocalToVworld(t3d3);
}
catch(RestrictedAccessException e)
{System.out.println(e);}
...
}
...
(I am trying to get the coordinates of several objects
loaded from a file)
When I run this code I have this exception:
javax.media.j3d.RestrictedAccessException: Node: local
to vworld transform is undefined for a node that is
not part of a live scene graph
How can I solve this problem and where can I find the
getLocalToVWorldTransform() class
Thanks in advance.
