I've been playing with anaglyphic stereo the last couple of days, mainly just to see what it's like, in doing so I've noticed a couple of issues which detract from it's enjoyment, I don't know much about this stuff so perhaps somebody who does might enlighten me.
1. For some reason, turning on Stereo at all seems to introduce SOME wire framing on some objects. For example, the UH1 doors, the walls of the hangar at SFO. Not everything is wireframed, and it doesn't matter what stereo method you choose, all seem to do it. 2. In anaglyphic mode, it's REALLY difficult to get correct alignment, the distance and separation values almost seem arbitrary (even taking measurements, I seem to need to fiddle with the sliders to a large degree). I wonder if there is not some units issue here. 3. When you do get the alignment right, it seems that you can get it right for a quite narrow "scene distance". For example, with the Cessna 150 I was using a few minutes ago, at SFO, I was able to get the alignment right for the cockpit area, looked great, yokes, throttle, buttons really popping out. But the runway markings, off into the distance, WAAAAY divergant, the centerline diverged further and further the more distant it got, not only not 3-d obviously but really quite rubbish. Similarly switching between cockpit and chase views, you can twiddle the sliders to make one or the other align, but not both. #1 I'd assume must be a bug somewhere in OSG? #2 I guess is probably just a matter of twiddling the sliders. #3 I don't know enough about the fundamentals here, is it correct for the two images to diverge further and further and further apart - the runway center line extending off into the distance for example? Would "perfect" anaglyphic glasses/monitor combination that don't "ghost" at all allow for such extreme divergence to "resolve" in your brain? Is it just a limitation of the technique that you can only really get one "scene distance" (whatever the correct term is) to align, and just have to accept that the further/closer in the scene you are looking than that distance the worse the alignment will be (and does this extend to other stereo methods, or just anaglyph)? Is there a bug in OSG/FlightGear which is making the divergence all screwy? ------------------------------------------------------------------------------ Nokia and AT&T present the 2010 Calling All Innovators-North America contest Create new apps & games for the Nokia N8 for consumers in U.S. and Canada $10 million total in prizes - $4M cash, 500 devices, nearly $6M in marketing Develop with Nokia Qt SDK, Web Runtime, or Java and Publish to Ovi Store http://p.sf.net/sfu/nokia-dev2dev _______________________________________________ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel
