I was kinda wondering why those goggles that have a screen in each eye and project a 3D world for you haven't caught on yet, but that got me to thinking about an even more basic way of doing 3D stuff, one that's been around almost forever on a technological timescale: those red-blue 3D goggles. So the question is, is whatever they use to generate those images doable on a 60-times-per-second-ish-basis, or does that take a lot of calculations. My gut instinct tells me you could just render the scene twice from two slightly different perspectives, shade on blue, one red, and then overlay them both with 50% opacity. But that is based on no fact whatsoever, so I'd like to know how doable this would actually be. And more importantly, if it is doable, what would the OGRE team think of implementing it? Wouldn't it be cool to have an Open-Source graphics engine provide the first, (to my knowledge), truly 3D games? Ok, I'm rambling, I'll stop now. -Calder
