I think you can only remove a branchGroup, and not a transformGroup. You could do that
using either...
1) branchGroup.detach();
2) simpleUniverse.getLocale().removeBranchGraph(branchGroup)
Take note that 2) is only applicable when the branchGroup to be removed is the added
to the simpleUniverse. However, if the branchGroup contains a morph object then this
would generate an exception bug, which Sun is aware of and would fix it in the next
release.
If you really need to remove a transformGroup then simply attach it to a branchGroup
and remove the latter by using any of the above 2 methods.
Hope this helps.
