You can do No.1 or No.3
No.2 could work but is not a good idea speciall if there are other objects behind it.
then chaning the color to background color wont help
No.3 will work if u have the object(s) in your branch group u have to Detach the
BranchGroup and remove the objects then Attach the branchgroup back

Subject: [JAVA3D] making an object(s) "disappear"
Hi:
I'm sure this must be documented somewhere but I have not been able to
find the answer, especially with j3d.org down ...
I have several 3d objects in my canvas and I want to allow the user to
turn off display of any object(s) s/he chooses. I can see several ways of doing
this ...
1. Make each object a BranchGroup and detach it when requested by the
user
2. Change the color or the object to the background color so the user
will no longer "see" it
3. "Detach" the object from the BranchGroup.
Does anyone have any input on what is the proper or best method? If #3
is the answer, could someone point me to some docs on how to do this?
Thanks,
Mona
