hi there,
i want to have I splitscreen for multiplayer issues, so far I see two ways to realize that in j3d:
use 2 instances of Canvas3D for onscreen rendering, but I guess this makes problems switching fastly between splitscreen and not…
use 1 onscreen Canvas(3D) and blit the images of two offscreen Canvas3Ds, but this sounds really slow…
other ideas ?

No.
IIRC, a View renders to one or more Canvas3D - and fills them. So my first guess is to have in fact 2 Canvas3D, maybe even tied together and maintained by Swing.
Not sure wether it can be done with SimpleUniverse, but at least it can be done without it. :-/
2.) The blitting method not necessarily has to be slow I think.
you may got me wrong,
IMHO the problem with two canvas3D for splitscreen is that I want to switch to single player modus at runtime so I need switching to 1 double-sized onscreen canvas and awt/swing component attchjing/detaching isn’t very fast…
I don’t assume the blitting itself to be slow. I thought about the offscreen rendering: I may be wrong, but is offscreen rendering fully hardware accelerated ?
1.) Is it not? Milliseconds? How often do you need to switch forth and back? Swing apps do it all the time…
2.) Yes, I assume offscreen rendering is as hardware accelerated as onscreen. I see no reason why it shouldn’t.
