Hello i am very greatfull for your input. If you can please explain how can i while running the program create new BranchGroups, change the transform groups in it.Because from what i have tried i have been unable to modify(transform group) them which i do so when i click the key board waking up a behavior class and trying to change the transform group. Currently i don,t know any thing about changing the branchgroups while running the application. If you have any books in digital form other than the help material on JavaSun pls mail them to me. Thanks a lot if it help i will mail you the code shortly.
