Hi Guys,

I am trying to add and remove Sphere objects to and from my universe
dynamically at runtime. However, each time I try to add a TransformGroup
child to the BranchGroup I get this error:

javax.media.j3d.RestrictedAccessException: Group: only a BranchGroup node
may be added

Can anyone please help me?

Thanks a billion in advance,
-Rouben

Just wrap each of your Spheres in a BranchGroup. They then can be
added and removed as wanted.

Have you already read the Java3D Tutorial, spanning 8 pdfs and resi-
ding on SUNs website?

Hi,

I think you can't transform a TransformGroup into a BranchGroup. But perhaps
you can add the spheres TransformGroup to another Branchgroup and than you
connect that one to the BranchGroup. Now you have a BranchGroup connected
as a child to a BranchGroup and it should be possible to add /detach it.

Cheers

Christian
