Unfortunately as Java3D only sees our 2 cards (and not the outputs) we have to put both the right wall and floor Canvas3D on the same screen. This means we can't alter screen based stuff without screwing up one canvas or the other.
It gets even better 'cos the floor's a different size to the walls. Any thoughts how to fix that? At the moment I have a different ViewPlatform for each wall with a transform group above to alter the view, it sort of works but the floor (or right wall) doesn't quite match. I've a feeling this is an SGI problem 'cos our NT box with a two-headed NVidia card just works.
