No. as long as you stay in the same universe all of our views will render the same
scene, which you have to define only once (in a future release you will be able to
scope parts of the scene to a specific view).
You build the graph e.g. like this:
VU - Locale - BG1 - Scenegraph
|____ BG2 - TG1 - VP1 - View1 - Canvas3d1
|____ BG3 - TG2 - VP2 - View2 - Canvas3d2
Us the Transformgroups TG1 and TG2 to set your "camera" to different positions. The
projection policy of View1 and View2 can be different.
Hope that helps.
