Hello All, I haven't been very active on the list lately but thought I'd chime in on this one.
1) There is no reason that you can not do stereo on a curved or angeled screen. If you can produce a single non-distorted image there's no reason you can't produce two. Now producing a non-distorted image on curved screens is a bit of a challenge but solutions are available. 2) OSG supports many different stereo formats type 'osgviewer --help-all' and look over the stereo options. Different technologies have different advantages and I'll let you read the literature to pick the ones that's best for your application. The only option that needs no specialized hardware is 'ANAGLYPHIC' where the stereo pairs are encoded in the color information and red/blue glasses are used. To use polarization you will need two (standard) projectors, polarizing filters, and a screen that maintains polarization. You are correct about the graphics access you are essentially rendering twice as many frames. If you are going to have more than two pairs of projectors you are going to need to look at synchronization across the screens so you don't get ripping.
