Situate a TransformGroup inmediatly after branchgroup and the rest of the
scenegraph after it.
in this way:
BG
|
TG < must be the rotation desired
|
Rest
I hope that helps you

Subject: [JAVA3D] rotate canvas3D (part 3)

: I'd like to rotate the canvas3D at 90 degrees, so I tryed two things :

work, I don't know why and I think it is not the good way

> - use postSwap and postRender methods, it does not work too, so I hope
that someone can explain me why :
