Well, as for keeping only BranchGroup.detach()... that is not the only
place you can detach. As I mentioned, you can detach a child from its
parent using Group.removeChild(index). As for optimization, you can
only do this if the capability bit is set. (Personally, I'm doing my
detach before the scene is live anyway.) So this whole question is
really just about ease of use.
How about this, in addition to the existing Group.removeChild(index), we
have Group.removeChild(Node). Then, the Group parent could search its
list, find the node, and call .removeChild(index) on its own. Then, one
step further, Node.removeFromParent() would just call
parent.removeChild(this). Does this make sense?
It's not that I can't do the Node.getParent(), then
Node.getChild(index), and do the search myself. I just don't want
EVERYBODY to half to write the SAME piece of code, assuming of course
that I'm not the only one that would want it. But you know what happens
when you ASSume... ;)
And, of course, the function would throw an exception if the capability
bit was not set.

Chris and the list,
Probably by keeping detach() in only BranchGroup it is easier to
do
the optimizations when a scenegraph is compiled. That would be my
guess.

Rob and everyone else,
On a related note then... why is there only BranchGroup.detach() and not
a
general Node.detach()? It makes scenes much larger when you have many
shapes, each with it's own BranchGroup to allow the shapes to be
detachable!
It would be more convenient to be able to have TransformGroup.detach(),
Shape3D.detach(), etc.
Chris

J. Lee,
I made this mistake (and asked this question a few months back).
There is a detach() method in BranchGroup that works fine.
