i did transformation to the viewer. i tried to combines translation, rotation and
scaling in one transformgroup so that i can feed this into the constuctor of the
Keyboard behavior (com.sun.*) . Any idea how to combine these into 1 transformation to
fit into 1 transformgroup so that i dont need to have separate transformgroup for
translation,rotation etc...
Thanks for the help..:-)
